How much is a dock and door business worth?

Short answer: commercial dock and door companies are priced on earnings, and the earnings buyers trust most are the ones under planned maintenance agreements with warehouses and plants — not last year's emergency calls. No verified trade-specific realized multiple exists for this niche in the data below, so this page builds from category data and says so plainly. See the Dock & Door page, then run your numbers in the valuation calculator.

The number

BizBuySell's trailing-five-year realized data has no separate dock and door category — this trade is too niche for its published tables, and any page quoting you a precise dock-and-door multiple from that source is making it up. Category data it is. Size moves the multiple more than almost anything. The IBBA Market Pulse survey (Q2 2026) puts realized pricing at 2.0x SDE for deals under $500K, 2.8x SDE at $500K-$1M, 3.1x SDE at $1M-$2M, 4.8x EBITDA at $2-5M, and 5.8x EBITDA at $5-50M. Same trade, same margins — a bigger, less owner-dependent business simply gets a different multiple.

For an anchor, public companies in Business & Consumer Services trade at 14.26x EBITDA — Damodaran Online, January 2026. No public company is a pure dock-and-door servicer; national facility-service platforms are the closest anchor, and they are labeled a proxy here. That is not your price. It is the opportunity-cost anchor a buyer measures your shop against: money parked in large, liquid companies earns that multiple, so a small, illiquid one has to be cheaper per dollar of earnings.

Worked example — shown math, assumptions labeled:

• Revenue: $2,400,000
• SDE margin: 20% — an assumption; parts-heavy commercial service carries real inventory and on-call labor costs
• SDE: $2,400,000 x 20% = $480,000
• Multiple: 3.1x SDE — IBBA tier for a $1M-$2M deal (Q2 2026)
• Indicated value: $480,000 x 3.1 = $1,488,000, before debt and before subtracting any customer who is about to be re-bid

How buyers actually value a dock and door business

This is a commercial trade, and buyers read it like one. The core asset is the installed base under agreement: every dock leveler, vehicle restraint, overhead door, and seal at every facility you inspect on a schedule. A planned maintenance agreement with a distribution center is recurring revenue with a purchase order behind it — buyers pay for that. Pure break-fix revenue, however profitable last year, is priced as a hope: the phone rings when something fails, and the facility manager who calls you can call anyone. Buyers then map account structure: multi-site logistics and food-production customers are worth a premium, but one DC at 30% of revenue is concentration with a forklift. They read your parts economics — planned work carries ordered parts at markup; emergency work carries truck stock, overtime, and price fights. And they check the safety file hard: your techs work around trailers, forklifts, and stored energy, so EMR, OSHA history, and lockout training records are valuation documents here, not HR paperwork. National platforms (the DuraServ model) buy exactly this: agreements, installed base, and documented safety.

What raises the price — and what kills it

Raises it:

• Maintenance agreements covering a counted installed base — doors, levelers, and restraints per site, in a system
• Multi-site accounts where one contract covers five facilities, none of them dominant
• Inspection programs that generate their own repair pipeline — deficiencies found, quoted, and closed
• 24/7 emergency coverage run by a rotation, not by your cell phone
• A safety record you can hand over: EMR, training logs, incident history, clean

Kills it:

• Break-fix only: no agreements, revenue that restarts at zero every January
• One warehouse or one 3PL above a quarter of revenue, up for re-bid next year
• Your name is the relationship at every facility — the plant engineer calls you, not the company
• Parts inventory nobody has counted since the last decade
• Safety incidents explained verbally instead of documented and corrected

Move your number

Convert inspections into agreements. Every facility you touch for emergency work is a maintenance-agreement prospect; moving even a fifth of break-fix revenue under agreement changes what a buyer sees — contracted, inspectable, renewable. The renewal reminders, inspection scheduling, and quote follow-up run on systems the ClaroPro team sets up for commercial service shops. Clean up commercial collections. Net-45 drift is silent margin loss; deposits on special-order doors and levelers, card and ACH options priced right, and progress billing on installs are the Finix payments team's territory. Build the installed-base register. A database of every asset you service — site, model, age, condition, last inspection — is both your sales pipeline and your buyer's diligence file; a Nova engineering team builds that when spreadsheets buckle. Run the result through the calculator, prefilled for dock and door.

Educational framework, math shown, not an appraisal — a real price is set by a real buyer on a specific day. The honesty here is not legal cover; it is owner protection. It keeps you from overpaying for a competitor whose agreements expire in March, from underselling your own installed base, and from signing a deal where the concentration risk was yours to see. We are on the side of the business owner, and showing the category label instead of inventing a trade multiple is what that looks like.
