SBA loans for glass and glazing contractors

What the figures show for glaziers

Glass and glazing contractors (NAICS 238150) took 326 SBA 7(a) loans from FY2024 through June 2026, worth $197,148,700, from 110 lenders. The figures describe a trade with a large-loan tail. The 90th percentile loan was $1,609,500, and 58 loans, 17.8% of the total, were $1 million or more, in a trade whose median loan supported five jobs. Many of those large loans are company purchases, whose median was $960,000.

Two credits under one code

The same NAICS code holds a commercial glazier installing storefronts and curtain wall on a subcontract to a general contractor, and a residential business replacing windows and installing shower doors and mirrors for homeowners. A lender underwrites them differently, and a file that does not make clear which it is gets read cautiously as both.

Franchise systems in this trade sell residential and service glass: shower doors, mirrors, window and glass repair. That places the 14.4% franchise share mainly in the residential half. The commercial half is where the bonding, retainage and WIP questions below apply, and where most large credits are likely to sit.

Retainage, pay applications and the WIP schedule

Commercial glazing is cash-hungry. Aluminum framing and fabricated glass are ordered and paid for long before they are installed, and the general contractor pays monthly against pay applications, holding back retainage until the project, or sometimes the whole building, is finished. A glazier on the last trade into a building can wait a long time for its retainage.

Lenders read that cycle through three documents. The AR aging, with retainage shown separately, because retainage is typically ineligible for a borrowing base and receivables more than 90 days past invoice usually are too. The work-in-progress schedule, which compares each job's billings with its costs and shows whether the company is overbilled, which is borrowing from its customers, or underbilled, which may be hiding a losing job. And the backlog, signed work not yet started, which tells a lender whether next year's revenue already exists.

A glazier that cannot produce a current WIP schedule will struggle with any lender that writes contractor credit.

A term loan does not solve a working-capital gap that grows with every new job. A line of credit sized to receivables and, for particular jobs, contract financing usually fit better. See lines of credit for contractors and what lenders look for in an AR aging.

Bonding and the loan

Much commercial glazing, public work especially, requires the glazier to provide performance and payment bonds. A surety sets a glazier's bonding capacity from its working capital, net worth and the owners' personal indemnity. That links the bond and the loan: an SBA loan that draws down working capital, or puts goodwill on the balance sheet after a purchase, can shrink the capacity that lets the company bid work. A careful borrower talks to its surety before it signs the loan, not after.

Lenders ask about bonding for the opposite reason. A bonded contractor has already been underwritten by a surety, which is some comfort. But a surety that pays a claim on a failed job steps into the contractor's rights on that job, including money the lender may have counted on. Lenders therefore want to know the bonded backlog, any claims history, and the terms of the indemnity agreement.

Buying a glazing company

Buyers took 57 loans, 17.5% of the industry's total and well above the 10.4% national share, at a median of $960,000 and 9.5%, nearly four times the industry's median loan. Established commercial glaziers are bought by competitors expanding into a new market, by their own project managers, and by searchers who see a trade with steady commercial demand. Loans above $350,000 fall in SBA's lowest variable rate-cap band, the base rate plus 3%.

• The estimator and project managers. A glazier's margin is won or lost in the estimate. Lenders ask who prices the work after closing, and whether they are staying.
• Bonding capacity. Whether the surety will bond the company under its new owner, and on what indemnity. A glazier that cannot bond after closing cannot bid much of its old work.
• Backlog and jobs in progress. Who bears the loss on a job that turns out badly after closing, and how retainage earned before closing is split.
• GC concentration. A company that does most of its work for two or three general contractors depends on relationships that may belong to the seller. See customer concentration in an acquisition.

SBA's change-of-ownership rules apply: an equity injection of at least 10% of total project costs, a seller note counting toward up to half of it only on full standby for the life of the loan, and no earnout, which matters when a seller wants to be paid on backlog that has not been built. The seller may consult for up to 12 months, or up to 24 months under SOP 50 10 8.1 from 1 October 2026. From 1 October 2026, a change of ownership must show debt service coverage of 1.25x on historical results, financial due diligence is required on every one, and a quality of earnings report on acquisitions of $3 million or more excluding real estate. See how SBA 7(a) finances an acquisition and earnouts and acquisition debt.

Start-ups, franchises and equipment

Start-ups took 16.9% of loans. On the commercial side the founder is commonly a project manager or estimator leaving a larger glazier. A lender lends on that person's record: the jobs run, the contractors who will give them work, and a realistic view of how long before a surety will bond a new company. SBA requires an equity injection of at least 10% of total project costs for a start-up. Franchise start-ups in the residential half are lent on the brand's record and the franchisee's own finances.

Glass trucks, cranes and lifts, and shop fabrication equipment can be financed on their own; 7(a) terms run up to 10 years for equipment, or 15 if its useful life supports it. SBA 504 financed 30 projects at a median of $555,000, mostly owned shops and fabrication space, where the company must occupy at least 51% of an existing building. See equipment financing vs SBA 7(a).

Preparing a glazing contractor's file

SBA's list is the base: business tax returns for 2–3 years, a P&L and balance sheet with a year-to-date P&L through last month-end, a debt schedule with copies of notes being refinanced, and personal tax returns and a personal financial statement for each owner of 20% or more. For a commercial glazier add:

• A current WIP schedule and the last year-end WIP
• An AR aging by customer, with retainage shown separately
• A backlog list: contract value, work remaining and customer
• A letter from the surety confirming bonding capacity
• An equipment list with any liens
• For a purchase, the seller's latest full year of figures and the letter of intent
