How to Value a Custom Cabinet Maker in 2026

Custom cabinet shops are one of the toughest small businesses to value — not because the math is complicated, but because no two shops look alike. One $3M revenue cabinet maker is a lifestyle business for a craftsman with three employees. Another is a 25-person production shop running two shifts on a Biesse Rover and pumping out kitchens for tract builders. Same revenue, completely different valuations.

I've worked on a dozen cabinet shop transactions over the years, and here's what the data actually shows about how these businesses get priced — and what owners can do to move their multiple.

The SDE Multiple Range

Custom cabinet makers trade in the 2.0-4.0x SDE range, with the median falling around 2.75x. That's lower than most construction trades for a reason: cabinet shops are capital-intensive, carry real inventory risk, depend heavily on a handful of builder relationships, and often live or die with the owner's design sense.

Where you fall in the range depends on four things: work mix (commercial vs residential), operational sophistication, designer/builder relationships, and how much of the business runs without the owner. A $350K SDE residential cabinet shop with one designer and no systems sells at 2.0-2.5x. A $700K SDE shop with a production manager, CNC workflow, and 40% commercial millwork revenue can push 3.5-4.0x.

Shops above roughly $1.5M EBITDA with commercial millwork focus occasionally attract strategic buyers and trade at 4.5-6.0x EBITDA. These are rare — most cabinet transactions are SMB-to-SMB deals.

Residential vs Commercial: The Margin Story

The residential custom kitchen market is the stereotype, but commercial millwork — bank branches, medical offices, retail buildouts, hospitality — is where the better businesses quietly operate. Commercial work carries higher margins (25-35% gross) and comes through GCs who pay on AIA draw schedules rather than homeowners who want to negotiate every change.

Residential custom shops average 18-26% gross margins, have longer sales cycles (design iterations, showroom time, homeowner indecision), and face serious competition from semi-custom brands like KraftMaid, Omega, and Medallion distributed through kitchen and bath dealers. These shops typically sell at 2.0-3.0x SDE.

Commercial millwork shops doing bank buildouts, dental office casework, retail fixtures, and hospitality work sell at 3.0-4.0x SDE, sometimes higher. The work is repeatable, the customers (GCs) rebid you annually, and margin discipline is stronger because you're quoting off documented drawings rather than negotiating with a homeowner.

A shop doing 70% commercial, 30% residential is the sweet spot most buyers want. All-commercial carries customer concentration risk through the GC channel, and all-residential is too dependent on the owner's personal design reputation.

Equipment: CNC Changes the Math

Cabinet shops run on equipment, and the gap between a CNC-equipped shop and a traditional hand-tool shop is enormous in buyer perception. A modern cabinet shop investment looks like:

• CNC router. A Biesse Rover, SCM Morbidelli, or Thermwood 3-axis runs $85K-$250K used, $180K-$500K new.
• Edge bander. IDM, Homag, or SCM Olimpic — $45K-$150K.
• Panel saw. Altendorf or SCM sliding table saw — $25K-$75K.
• Drilling/boring. Vitap or Biesse Skipper for line boring — $30K-$120K.
• Spray booth and finishing line. $40K-$200K depending on automation.
• Dust collection and compressed air. $25K-$75K for a properly scoped system.

A well-equipped custom shop sits on $400K-$1.5M in equipment replacement value. Buyers care less about the raw equipment number and more about what it signals: is this shop running on modern workflows (CabinetVision, Mozaik, or Microvellum driving the CNC), or is it a traditional bench-build operation where every project is a custom engineering exercise?

The software integration matters more than sellers realize. A shop running CabinetVision into a Biesse CNC with automated nesting and optimized cut lists is worth meaningfully more per dollar of SDE than a shop doing the same revenue with hand-drawn cut lists. It tells the buyer the process is transferable.

Designer and Builder Relationships

This is where residential cabinet shops get valued — or don't. If you work with a handful of high-end custom home builders, interior designers, and kitchen and bath dealers who feed you consistent work, that referral network is an asset. But it's also fragile.

The hard question buyers ask: "How many of these designer relationships transfer when the owner leaves?" If you're the one sitting in the showroom pitching layouts and working with the homeowner, the answer is often "half of them, maybe." That uncertainty is why residential cabinet shops trade at the low end of the range and why earn-outs are common.

The shops that do best have a project manager or lead designer who isn't the owner, written referral agreements with builder partners, and a documented history of repeat work from the top 10-15 accounts.

Actionable tip: Two years before sale, start transitioning client relationships to a designer employee. Introduce them into the conversations. Have them sit in on design meetings. Buyers will verify during diligence that the relationships aren't exclusively yours.

Shop Space and Lease Terms

Cabinet shops need space — usually 8,000-25,000 square feetof clear-span industrial with 16-20 foot ceilings, 3-phase power, loading dock access, and adequate dust collection infrastructure. That kind of space isn't cheap or easy to find in most metro markets anymore, especially as industrial real estate has tightened.

If you own the building, decide early whether it's part of the deal or a separate lease to the buyer. Most cabinet shop transactions structure the real estate as a separate lease at market rent (typically $8-15/sq ft NNN depending on market). That's cleaner for both sides and lets you hold the real estate as a retirement asset.

If you rent, the lease is a deal-critical document. Fewer than 5 years remaining with no renewal options will kill SBA financing and cost you 0.5x SDE or more. Lock in a 10-year lease with two 5-year options before going to market.

What Kills Cabinet Shop Value

Owner as lead designer AND estimator AND production manager. The most common cabinet shop structure, and the most damaging to valuation. Expect buyers to structure earn-outs of 30-50% of the price and discount the upfront multiple accordingly.

Inventory that can't be counted. Raw material (plywood, hardwood, hardware) and work-in-process are real balance sheet items. A shop with $400K in uncounted, disorganized inventory looks like a diligence problem. Cycle-count and reconcile before listing.

Thin margins masked by owner comp. If your SDE is $500K but the actual operating EBITDA (after replacing your labor at market rate) is $150K, sophisticated buyers will see it and price off EBITDA, not SDE.

Missing or weak safety record. Cabinet shops have real injury exposure (table saws, jointers, forklifts, finishing chemicals). An EMR above 1.0 and any OSHA history around wood dust or combustible dust compliance will come up in diligence.

Maximizing Value Before Sale

• Shift mix toward commercial millwork. Even 20-30% commercial revenue lifts the multiple meaningfully.
• Implement or upgrade your CNC workflow. CabinetVision or Microvellum driving a modern CNC is a multiple-enhancing story.
• Develop a designer who isn't you. This is the single biggest move in residential shops.
• Clean up the shop floor. Buyers judge operational sophistication by what they see when they walk in. 5S matters.
• Document processes. Written SOPs for estimating, cut lists, assembly, and installation make the business feel transferable.
• Lock in the lease. 10 years with options, before listing.

The Bottom Line

Custom cabinet shops are tough businesses, and the valuation reflects it. But the spread between a 2.0x SDE sale and a 4.0x SDE sale is enormous — on a $600K SDE shop, that's $1.2M. The shops that get the top of the range have professionalized their operations, diversified into commercial millwork, developed design talent beyond the owner, and invested in modern CNC workflows. Start building those things now if you're thinking about an exit in the next few years.
