Buying a Glass and Glazing Business
Why Searchers Target Glass and Glazing
It is the smallest of the build and finish trades by establishment count: about seven thousand employer businesses, half of them under five employees, and average receipts near two and three quarter million dollars. The work is skilled, the material is expensive and slow to arrive, and the crews who hang a curtain wall are not interchangeable with general labor. That is a defensible position for a small company, and it is why the trade holds together against consolidation better than its size would suggest.
What the Market Pays
No sold-listing publisher prices glazing on its own. The band used here comes from sold listings in the building and construction class, 1.81x to 3.13x owner earnings with the middle at 2.43x. That class scope sentence does not name glass or glazing at all, so treating it as this trade's band is a judgment about which class the work resembles. An appraisal firm publishes a trade-specific 2.12x to 2.83x, which sits entirely inside the marketplace band and is narrower than it. That is the tell that it describes a typical business and not a distribution.
Half the Revenue Is Somebody Else's Contract
Fifty-one percent of this trade's receipts arrive as work subcontracted in from another contractor, the highest share of any of these trades. That means half the book is billed through a schedule of values, paid on a general contractor's cycle, and held behind retainage. It also means the payment terms in the top subcontracts are worth more scrutiny than the customer list. In some states a clause making the general contractor's own payment a precondition of paying the sub is void by statute, and in others it is enforceable and compounds with retainage.
What the Shop Fabricates Is a Regulated Product
Federal consumer product safety rules cover glass in doors, tub and shower enclosures and sliding patio doors, and they say plainly that fabricators are considered manufacturers of those products. A glazing shop that builds a shower enclosure is therefore a manufacturer with certification and labeling duties and product liability behind them. Residential shower and tub work is a large and quiet revenue line in this trade and it carries a tail that nobody prices at the table.
What to Verify in Diligence
Two of these are about getting paid and two are about what the shop built. All four are documents.
- Retainage receivable by job and by age, and the payment clause in the top five subcontracts
- The split between engineered curtain wall and stock storefront, by revenue and by gross margin
- Insulating glass unit certification for the products installed, and the seal warranty terms actually given
- Physical inventory of glass at closing, since material runs about forty percent of receipts
- Which state credentials the company holds, and whether the state still issues them
Financeability Notes
Materials at forty percent of receipts is the highest of these trades, so glass price and lead time hit margin directly and an accurate count at closing carries real weight. Half the revenue on somebody else's payment cycle makes the working capital line the credit question. Fifteen percent government work puts bonding into a trade whose median business is under seven employees. And the license answer moved recently. Florida repealed its glass and glazing specialty certification in May 2024, so a buyer there inherits no state credential because there is no longer one to inherit. California, Nevada and Virginia license the work, and none of those licenses transfers on a sale.

What It Costs to Replace the Owner
The multiples above are quoted on SDE, which adds the owner's pay back into earnings, so they hold only if you do the owner's job. Hire someone instead and the going rate for the role comes back out. For this trade that is usually the lead who runs the trade crews, paid a median of $79,920 a year nationally. Subtract it from SDE before applying any multiple, because at a 3x multiple that wage also takes about $239,760 off what the business is worth to you.
