Window and Door Business Valuation in 2026: Real Multiples by Operator Type

Buy-side M&A across 76+ active capital partners · Home services M&A: windows, doors, exterior remodeling, roofing, HVAC · Updated June 24, 2026

Window and door business valuations vary sharply by channel: replacement-install operators selling direct to homeowners trade meaningfully higher than new-construction installers selling through builders. The 2026 range runs from 3x SDE for small founder-led shops to 8x EBITDA for documented replacement-focused operators, with PE platforms paying 7x-10x for $3M+ EBITDA businesses that show consistent set-rate, demo-to-close ratios, and a captive financing partner. The reason is structural: replacement business is a lead-gen and sales operation with predictable unit economics, while new-construction is a contract-bid business with thin margins and customer concentration in a handful of builders. This guide maps the channel split, decodes how PE buyers actually underwrite a window and door business valuation, walks through a worked example on a $1.5M EBITDA Florida Renewal by Andersen franchise, and identifies the pre-sale moves that produce the most multiple lift. A deeper read on football field valuation covers the same ground with the supporting data.

Methodology and data sources

This valuation guide follows CT Acquisitions’ 5-tier source hierarchy: T1 press releases for major sponsor and platform transactions (Apex Service Partners, Renovo Home Partners, Great Day Improvements), T2 SEC filings of public-company comparables (Cornerstone Building Brands historical filings before the 2022 Clayton Dubilier & Rice take-private; JELD-WEN Holding NYSE: JELD), T3 sponsor portfolio pages, T4 industry-research publishers (Peak Business Valuation, Axial, First Page Sage, Capstone Partners, BizBuySell, Window & Door magazine, Dodge Construction Network), and T5 M&A trade press. Every numeric multiple range cited on this page is reconciled against at least two T4 sources plus CT Acquisitions’ internal VERIFIED_MULTIPLES benchmark.

Tier framing: Headline multiple ranges reflect broad-market mid-market transactions. Premium PE-platform-tier multiples (where cited) reflect institutional-buyer underwriting on businesses that clear specific scale, replacement-mix, set-rate, and management-bench thresholds; they are not universally available and require platform-quality operator characteristics.

Verification window: All multiples and operator-tier figures verified June 2026 against the named T4 publishers’ most-recent reports plus CT’s active-engagement data. Multiples by tier are sensitive to credit-market conditions, replacement-mix, geography, and lead-gen efficiency; the cited ranges are starting points for transaction-specific valuation, not deal-specific quotes.

Window and door industry-data sources: Peak Business Valuation home-improvement contractor data, First Page Sage service-companies aggregate, Window & Door magazine’s Top 100 Dealers list (annual). Andersen Corporation is privately held by descendants of founder Hans Andersen and is the parent of Renewal by Andersen LLC; Pella Corporation is also privately held, employee-owned through its Pella Mutual Trust Company. Cornerstone Building Brands (parent of Ply Gem windows and Simonton) is owned by Clayton Dubilier & Rice after the May 2022 take-private at $24.65 per share. JELD-WEN Holding (NYSE: JELD) is the public-company comparable for door manufacturers. The CT VERIFIED_MULTIPLES window-and-door lock is 3.5x-6.5x EBITDA broad market for installers with 7x-10x reserved for replacement-led PE-platform candidates with documented funnel economics.

The short answer: typical window and door valuations in 2026

*PE-platform tier reflects publicly disclosed PE-backed home-improvement transactions; see Apex Service Partners’ Alpine Investors backing (April 2019), Renovo Home Partners formed by Audax Private Equity (October 2021), Great Day Improvements LLC owned by Littlejohn & Co. since November 2020. These multiples apply only to platform-quality operators (multi-market footprint, proven replacement funnel, professional management). On valuation specifically, our overview of private equity platforms by sector covers the cap-table behind these buyers.

The four window and door business models

Before any valuation analysis, identify which of these models describes your business. The valuation calculus is fundamentally different across them.

1. Replacement install (direct-to-homeowner)

The premium model. Homeowner-funded replacement of existing windows and doors, sold through in-home consultations, marketed via paid digital, direct mail, home shows, and canvassing. Average ticket: $12,000 to $35,000 per project, with $1,200 to $2,500 installed cost per opening per Window & Door magazine 2025 Top 100 Dealers reporting. Gross margins: 38% to 52%. Customer acquisition cost: $150 to $450 per qualified lead, scaling to $1,500 to $3,500 per closed sale at 70% set rate and 35% demo-to-close. Valuations 5x to 10x EBITDA depending on scale, set-rate, and financing capture.

2. New-construction installer (builder channel)

Installation for production homebuilders and custom-home contractors. Volume-based, bid-driven, recurring through builder relationships but not through end customers. Gross margins compressed to 18% to 28% because builders extract price concessions on large-unit-count orders. Customer concentration high: top three builders often represent 60% to 85% of revenue. Valuations 3x to 4.5x SDE because builder contracts do not transfer cleanly and key-person relationships dominate. Cyclical with housing-starts data (US Census Bureau monthly housing starts and permits release).

3. Commercial and multifamily glazing

Commercial storefront, curtainwall, and multifamily window installation. Project-based, $50K to $5M per project, AAMA certification often required, IRC compliance and energy-code compliance (IECC 2021 or local equivalent) standard. Gross margins: 22% to 32%. Long sales cycles, contract retention, and bonding requirements separate this from residential work. Valuations 4x to 6x EBITDA. Different buyer pool: commercial construction strategics, not residential PE platforms.

4. Specialty and storm protection

Impact-rated windows and doors (Florida HVHZ Miami-Dade NOA certified, coastal markets per ASCE 7-22 wind-load tables), hurricane shutters, custom architectural doors (mahogany, steel, specialty glass), and historic-replication windows. Higher gross margins (40% to 55%) due to product differentiation and limited competition. Florida market specifically benefits from post-2002 IRC and Florida Building Code 8th Edition (2023) impact requirements. Valuations 5x to 8x depending on certification depth and recurring repair revenue.

Most window and door businesses are dominantly one of these models with secondary exposure to a second. A business that is 80% replacement install with 20% builder work is valued primarily as a replacement business. Flip the mix and the valuation calculus flips with it.

Where the real value lives: replacement install

Replacement install is the only sub-category where window and door operators routinely command 7x to 10x EBITDA multiples. Understanding why matters:

• Homeowner-funded demand is recession-resistant. Replacement is driven by failure (seal failure, frame rot, hurricane damage), energy-bill pain, and curb-appeal upgrades, not by housing starts. The Joint Center for Housing Studies of Harvard University’s Leading Indicator of Remodeling Activity (LIRA) projects steady residential remodeling spending through 2026.
• Unit economics are knowable. Lead cost, set rate, demo-to-close, average ticket, gross margin per opening: every step is measurable. PE buyers can underwrite the funnel and forecast revenue with high confidence.
• Customer acquisition is repeatable. Paid digital, direct mail, canvassing, home shows, retail kiosks (Home Depot, Costco partnerships) all produce leads at known cost. Replacement marketing is an industrial process.
• Financing partners amplify ticket size. GreenSky (acquired by Sixth Street Partners in March 2024), Synchrony Home Improvement, and Service Finance Company (owned by Truist since the BB&T acquisition closed) all provide consumer financing that lifts average ticket 20% to 35% versus cash-only.
• Manufacturer rebates compound margin. Renewal by Andersen, Pella, Andersen 400 series, Marvin, Provia, ProVia, and Therma-Tru all offer dealer rebate programs tied to volume tiers. Top-tier dealers earn 4% to 8% back on cost.

If you are primarily a new-construction operator considering a sale, the highest-ROI 2 to 4 year investment is building a direct-to-homeowner replacement book. It is slow and requires marketing and sales capability the builder channel does not develop, but produces durable multiple expansion.

How window and door buyers calculate the number

1. Normalize the EBITDA. Adjust for owner compensation, related-party rent on yard or showroom, personal expenses, and franchise royalty timing. Renewal by Andersen royalties (typically 5% to 7% of revenue per franchise disclosure documents) must be modeled forward.
2. Decompose the revenue. Split by channel (replacement install, new-construction, commercial, specialty) and within replacement, by product mix (windows, entry doors, patio doors, sliders).
3. Analyze the funnel. Lead source attribution, lead cost by channel, set rate, demo-to-close ratio, average ticket, gross margin per opening. This is the single most intensive part of replacement diligence.
4. Model forward cash flow. Project forward revenue with explicit lead-cost inflation, set-rate sustainability, and competitive market assumptions.
5. Compare to comparables. Adjust for geography, climate, franchise affiliation, financing partner relationships, and labor model.
6. Apply the concluding multiple.

The six factors that move window and door multiples

1. Replacement vs new-construction mix

The single largest valuation driver. A replacement-led business at 80%+ direct-to-homeowner revenue with documented funnel economics trades at 6x to 8x EBITDA. A primarily new-construction operator trades at 3x to 4.5x SDE. This is a 2-to-3 turn differential, worth $2M to $4M on a $1M EBITDA business. Buyers will trace every revenue dollar to its origin channel during diligence.

2. Set-rate and demo-to-close discipline

Within replacement install, funnel discipline matters:

• Premium funnel: set rate 72%+, demo-to-close 38%+, average ticket $18,000+, financing attach 55%+, lead cost under $300 qualified.
• Strong funnel: set rate 65% to 72%, demo-to-close 32% to 38%, average ticket $14,000 to $18,000, financing attach 40% to 55%.
• Average funnel: set rate 58% to 65%, demo-to-close 26% to 32%, average ticket $11,000 to $14,000, financing attach 25% to 40%.
• Weak funnel: set rate under 58%, demo-to-close under 26%, average ticket under $11,000, financing attach under 25%.

Buyers will rebuild this analysis in diligence using the operator’s CRM data (typically MarketSharp, ImproveIt 360, or Salesforce). Detailed, accurate funnel reporting is non-negotiable for platform-grade pricing.

3. Franchise affiliation and territory rights

The franchise question is the most misunderstood lever in window and door valuation. Four primary franchise structures exist:

• Renewal by Andersen (Andersen Corp subsidiary): exclusive territory, product exclusivity on Fibrex composite frames, royalty 5% to 7% of revenue plus marketing co-op contribution. Territory transfer subject to Andersen Corp approval; the parent has right of first refusal in most franchise agreements. Trades 5x to 7x EBITDA for single-territory operators; multi-territory operators can clear higher with Andersen Corp consent.
• Pella ProDealer: non-exclusive dealer network owned by Pella Corporation (employee-owned through Pella Mutual Trust Company). No royalty in the franchise sense; revenue model is product margin and rebate. More flexible at exit because no franchise transfer fee applies.
• Window World franchise: 200+ franchise locations across the US per Window World corporate site. Franchise fee plus ongoing royalty (per franchise disclosure documents, typically 3% to 5%). Multi-unit franchisees command higher multiples due to documented systems.
• Independent dealer: no franchise constraints, full proceeds at exit, but no territory protection and no national brand. Independents with strong local brand and funnel discipline often outperform franchised competitors on net proceeds because royalty load disappears at exit.

4. Lead-gen economics and channel diversification

Lead cost discipline separates platform-grade operators from cash-flow-stressed independents:

• Paid digital (Google, Meta): $150 to $450 per qualified lead in 2026, with national averages above $300 per the Local Search Association 2025 home-improvement vertical report.
• Direct mail: $80 to $250 per qualified lead, depending on geography and creative.
• Home shows and events: $200 to $400 per qualified lead at scale.
• Retail partnerships (Home Depot, Costco, Lowe’s): revenue-share rather than lead-cost model, with retailer keeping 12% to 22% of project revenue.
• Canvassing: $100 to $250 per qualified lead in dense suburban markets.

Buyers reward channel diversification. Operators with 60%+ of leads from a single source (typically paid digital) carry concentration risk and trade at a 0.5x to 1x discount versus operators with 4 to 6 active channels at meaningful volume.

5. Financing partner attach rate

Consumer financing is the single most overlooked margin lever. The major players:

• GreenSky (Sixth Street Partners portfolio since March 2024): historically the dominant home-improvement financing platform; 12-month no-interest promo programs are the funnel standard.
• Synchrony Home Improvement (NYSE: SYF): deep-subprime and prime offerings, strong revolving program.
• Service Finance Company (Truist subsidiary): installment loans with strong contractor portal and quick approvals.
• EnerBank USA (now Regions Bank Home Improvement Financing after 2021 acquisition): long-tenured contractor financing brand.

Operators with 50%+ financing attach run 2 to 4 percentage points higher gross margin (financed projects skew larger ticket and reduce price-sensitivity in the close) and trade 0.5x to 1x higher than cash-only operators.

6. Technology and operational systems

• Premium: MarketSharp, ImproveIt 360, or Salesforce with 2+ years of clean funnel data. Documented installer protocols, route optimization, post-install warranty system, NPS tracking.
• Standard: basic CRM with appointment-set tracking but limited funnel reporting.
• Discount: spreadsheets and verbal-handoff sales process. Post-close technology implementation costs $150K to $400K and takes 9 to 18 months.

Other factors buyers evaluate

Installer crew composition and W-2 vs subcontractor mix

W-2 installers carry higher labor cost but better quality control and lower IRS reclassification risk (relevant since the 2024 DOL final rule on independent contractor classification, effective March 11, 2024). Subcontractor models are common but carry compliance risk. Buyers value documented installer training and dedicated W-2 install crews on premium products.

Warranty and callback exposure

Installation warranty (typically 2 to 10 years labor) plus product warranty pass-through (manufacturer-backed). Callback rate above 6% of installs signals quality issues; buyers will normalize warranty reserves and may require an escrow or holdback.

AAMA, NFRC, and energy-code compliance

American Architectural Manufacturers Association (AAMA) certification, National Fenestration Rating Council (NFRC) labeling, and IECC 2021 energy-code compliance. ENERGY STAR Most Efficient 2025 certification carries marketing weight in eco-conscious markets. Documentation of code compliance and licensing per state requirements is expected diligence.

State licensing and bonding

State contractor license requirements vary (Florida CILB, California CSLB, Texas TDLR, etc.). Surety bonding for projects above state thresholds. Buyers review license status and disciplinary history.

Real estate and showroom operations

Many replacement operators run a showroom (typically 2,000 to 8,000 sqft) plus warehouse for product staging. Owned versus leased; long-term lease arrangements often serve both seller and buyer well. Showroom traffic as a lead source is meaningful in suburban markets.

Geographic footprint and territory protection

For franchised operators, territory boundaries matter at exit. For independents, market density and brand recognition matter. Single-market focus with deep penetration is preferred for sub-$3M EBITDA operators; multi-market footprint becomes platform-grade above $3M EBITDA.

Worked example: $1.5M EBITDA Florida window replacement RBA franchise

Business profile:

• $11M revenue, $1.5M reported EBITDA (13.6% margin)
• Mix: 88% replacement windows and patio doors, 8% entry door replacement, 4% storm protection upsell
• Renewal by Andersen franchise covering greater Tampa Bay metro, 6.5% royalty plus 2% marketing co-op
• Funnel: 72% set rate, 36% demo-to-close, $17,200 average ticket, 58% financing attach (GreenSky and Synchrony)
• 4,400 qualified leads in trailing 12 months at blended $285 cost per qualified lead
• 3 in-home sales reps plus founder; founder still runs 25% of demos
• 22 W-2 installers across 11 install crews; year-round work (Florida)
• MarketSharp CRM with 3 years clean funnel data
• Showroom in Tampa (4,200 sqft) on 5-year lease with 5-year option
• Florida HVHZ Miami-Dade NOA certified product line; impact-rated installs are 18% of mix at premium gross margin
• Owner comp $220K, replacement GM $165K. Personal expenses $35K. One-time RBA conversion costs from prior brand $40K.

EBITDA normalization:

• Reported EBITDA: $1.5M
• Owner compensation adjustment: +$55K
• Personal expenses: +$35K
• One-time costs: +$40K
• Normalized EBITDA: $1.63M

Multiple assessment:

• Starting benchmark for replacement-led RBA franchise, documented funnel: 6.5x
• +0.4x for premium funnel metrics (72% set, 36% close, 58% financing attach)
• +0.2x for Florida year-round market and impact-rated product mix
• +0.2x for MarketSharp 3-year data history
• −0.4x for founder still running 25% of demos
• −0.2x for single-territory franchise (Andersen Corp transfer approval required)
• Concluding multiple: 6.7x

Indicative valuation: $1.63M × 6.7x = $10.92M

18-month improvement path:

• Transition founder out of demo seat, hire 4th sales rep and elevate top performer to sales manager: multiple to 7.1x. Outcome: $11.57M.
• Push financing attach from 58% to 68% via Service Finance addition: average ticket lift to $18,500, EBITDA to $1.74M. Outcome: $12.35M.
• Add second territory (Sarasota) via Andersen Corp consent: multiple to 7.5x on combined $2.2M EBITDA. Outcome: $16.5M.
• Combined: plausible multiple 7.6x on $2.4M EBITDA. Outcome: $18.24M.

$7.3M delta over 18 months of preparation, more than the original valuation.

How to increase your window and door business value before selling

Highest ROI

• Build replacement mix above 75%. If below 50% replacement, hire a dedicated direct-to-homeowner marketing manager 18+ months before sale. Target paid digital, direct mail, and home-show channels with disciplined attribution.
• Lift set rate to 70%+ and demo-to-close to 35%+. Hire a dedicated appointment-setter team. Train sales reps on the consultative one-call-close methodology common in the replacement vertical (Sandler, Sales Edge, or proprietary).
• Push financing attach above 55%. Add a second financing partner if you only have one. Train sales reps on financing as a value-stacking tool, not a discount.
• Transition founder out of the sales seat. Buyers heavily discount founder-dependent revenue. Promote a top sales rep to sales manager 12 to 18 months before sale.
• Hire a non-selling GM. 18 to 24 months runway. A documented org chart with non-owner ops, install, and sales leadership clears the path to platform-grade pricing.

Medium ROI

• Implement MarketSharp or ImproveIt 360 if not on a vertical-specific CRM.
• Diversify lead channels: target 4 to 6 active sources with no single channel above 40% of leads.
• Document installer training program and W-2 conversion plan if running heavy subcontractor model.
• Build out storm-protection or specialty-door upsell capability to lift average ticket.
• Pursue manufacturer rebate tier upgrades (top-tier Andersen 400, Marvin, Pella) by consolidating purchasing.

Lower ROI

• Website redesign.
• Social media engagement.
• Vehicle wrap refresh.

Common mistakes that destroy window and door valuations

• Set rate and demo-to-close not tracked in CRM. Verbal-handoff sales process with no funnel reporting forces buyers to underwrite blind. Multiple compression of 1 to 2 turns is standard.
• Subcontractor-heavy install model with no W-2 conversion plan. Post-2024 DOL rule changes raised the bar for proper classification. Buyers will model reclassification cost into the bid.
• Builder-channel concentration above 60% without a replacement build plan. Limits multiple ceiling severely. Builder relationships do not transfer cleanly at exit.
• Single lead channel above 60% of qualified leads. Concentration risk: a single Google Ads account change or direct-mail vendor failure can wipe out the funnel.
• Founder running 30%+ of demos at close. Post-close revenue continuity is at risk. Buyers will require earn-out or escrow.
• Renewal by Andersen franchise without territory expansion path. Single-territory franchises cap valuation. Andersen Corp transfer approval is a known risk that needs to be addressed pre-LOI.
• Warranty callbacks above 6% of installs. Quality issues force warranty reserve adjustments and may trigger holdback or escrow.
• Cash-collected revenue not booked on invoice date. Tax-return-only financials force buyers to discount EBITDA for unverifiable cash. Clean accrual-basis books with monthly close are non-negotiable for replacement businesses above $5M revenue.

Window and Door Business Valuation Multiples

Window and door business valuation multiples typically run 3x to 4.5x SDE for owner-operated installers leaning on new-construction or builder work and 4x to 8x EBITDA for replacement-led installers selling direct to homeowners. The single biggest driver is channel mix: a company built on direct-to-homeowner replacement install trades far higher than one reliant on builder contracts. PE-platform-grade replacement businesses with documented funnel economics and consumer financing capture clear 7x to 10x EBITDA at $3M+ EBITDA scale.

The factors that move a window and door valuation most are replacement mix, set-rate and demo-to-close discipline, consumer financing attach rate, lead-channel diversification, and franchise or independent positioning. Converting builder-channel revenue to direct-to-homeowner replacement is the most reliable way to lift the multiple.

Frequently asked questions about window and door business valuation

What is the average window and door business multiple in 2026?

Across all transactions, simple average is 4.5x to 6x EBITDA. Replacement-led operators with documented funnel trade at 6x to 8x. New-construction installers trade at 3x to 4.5x SDE. PE-platform-grade replacement businesses at $3M+ EBITDA clear 7x to 10x. The channel mix and funnel discipline matter more than the headline revenue.

Is a Renewal by Andersen franchise worth more or less than an independent?

Both clear strong multiples when run well. RBA franchises trade 5x to 7x EBITDA for single-territory operators, with multi-territory operators clearing higher with Andersen Corp consent. Independents with similar funnel metrics often clear higher net proceeds because the 5% to 7% royalty load disappears at exit. The franchise question reduces to: does Andersen Corp’s brand, lead-gen support, and product exclusivity generate enough lift to outweigh the royalty drag? For most operators in the first 5 years, yes. For mature operators with strong local brand recognition, the math gets closer.

How much does replacement mix really add to my valuation?

A lot. Shifting from 30% replacement to 80% replacement can expand the multiple from 4.5x to 7x, producing a 55%+ increase in valuation at constant EBITDA. This is the single most impactful pre-sale improvement available to most window and door operators.

Do I add back owner salary to EBITDA?

Partially. Normalize to a market-rate replacement cost. For a $1.5M EBITDA window and door business, the add-back is typically $55K to $90K on owner compensation, plus add-backs for personal expenses and related-party transactions. If the founder is still running 25%+ of in-home demos, expect buyers to discount the add-back because the sales role is not fully replaceable.

Should I add a second financing partner before selling?

If you only have one financing partner and attach rate is below 50%, yes. Adding a second partner (typically GreenSky plus Synchrony, or Service Finance plus EnerBank-now-Regions) lifts attach rate by 8 to 15 percentage points, which lifts average ticket and gross margin. The EBITDA lift typically pays for the integration cost within 6 months.

How do buyers evaluate my funnel metrics?

They rebuild the funnel from raw CRM data. Lead source by channel, set rate, demo-to-close, average ticket, gross margin per opening, financing attach rate, callback rate. Aggregate metrics are calculated and compared to industry benchmarks (Window & Door magazine Top 100 Dealers reporting; Apex Service Partners, Renovo Home Partners, Great Day Improvements portfolio reporting where public). Clean MarketSharp or ImproveIt 360 data is non-negotiable for platform-grade pricing.

Is W-2 vs subcontractor labor a valuation issue?

Yes, especially after the March 11, 2024 DOL final rule on independent contractor classification. W-2 install crews carry higher labor cost but lower reclassification risk and better quality control. Subcontractor-heavy models with no W-2 conversion plan trade 0.5x to 1x lower because buyers model future reclassification cost into the bid.

How long does it take to sell a window and door business?

90 to 150 days from LOI to close for a well-prepared replacement-led business. Preparation runway is 6 to 24 months depending on starting position. Funnel data cleanup and founder transition can extend timelines. Franchise transfer approval (RBA, Window World) adds 30 to 60 days.

How much will I pay in taxes on the sale?

Federal long-term capital gains plus 3.8% NIIT on goodwill portion. State taxes vary. Structural planning can reduce effective rate. See our complete selling playbook.

What is the best time of year to sell a window and door business?

Most replacement operators prefer to close after Q2 or Q3, when trailing 12 months reflects the spring and summer selling peak. Buyers prefer to have a clean trailing 12 months that includes a full home-show season and a recent peak summer. LOI timing typically aligns with late summer or fall; close in winter or early spring.

What is the typical multiple for a window and door business?

2026 multiples range from 3x SDE for new-construction installers to 8x EBITDA general market for replacement-led operators, with PE-platform-quality multi-market players reaching 7x to 10x (deal-specific support required). Most transactions fall between 4.5x and 7x. Replacement-led operators command 6x to 8x; new-construction-led operators trade at 3x to 4.5x SDE.

How is a window and door business valued?

Revenue decomposition by channel (replacement, new-construction, commercial, specialty), funnel rebuild from CRM data (set rate, demo-to-close, average ticket, financing attach), franchise affiliation review, installer model assessment (W-2 vs subcontractor), and AAMA, NFRC, IECC, and state-licensing compliance check.

What is the most valuable type of window and door business?

Direct-to-homeowner replacement install with documented funnel: set rate above 70%, demo-to-close above 35%, average ticket above $15,000, financing attach above 50%, lead-channel diversification across 4+ sources, and non-selling founder with established sales-management bench. This segment trades at 7x to 10x for quality operators at $3M+ EBITDA.

How much is a window and door business with $1.5M EBITDA worth?

Replacement-led franchise (RBA, Pella ProDealer) with documented funnel: $9M to $12M. Mixed replacement and new-construction independent: $6M to $9M. New-construction-led at this size is unusual; typically valued on SDE at 3x to 4.5x.

Do Renewal by Andersen franchises hold their value at exit?

Yes when properly transferred. Andersen Corp retains right of first refusal in most RBA franchise agreements and must approve any territory transfer. The process adds 30 to 60 days to closing. Multi-territory RBA operators with Andersen Corp relationships in place clear higher than single-territory operators because the parent prefers consolidation among proven franchisees.

Is replacement install or new-construction more valuable?

Replacement install. Direct-to-homeowner revenue is recession-resistant, higher gross margin, and not dependent on builder relationships that do not transfer. New-construction is bid-based, builder-concentrated, and cyclical with housing starts. The valuation differential is 2 to 4 turns of EBITDA in most markets.

How do I increase my window and door business value before selling?

Build replacement mix above 75%, lift set rate to 70%+ and demo-to-close to 35%+, push consumer financing attach above 55%, diversify lead channels across 4 to 6 sources, hire a non-selling GM and sales manager 12 to 24 months before sale, and document funnel metrics in MarketSharp or ImproveIt 360 for at least 24 months pre-LOI.

How does consumer financing affect window and door valuation?

Materially. Operators with 50%+ financing attach run 2 to 4 percentage points higher gross margin and lift average ticket 20% to 35% versus cash-only. Adding GreenSky, Synchrony, Service Finance, or Regions (formerly EnerBank) as a secondary financing partner is one of the highest-ROI pre-sale moves available.
