This page covers broken shop windows, glass entry doors and office glass. Bob Vila says the large fixed panes in a storefront window run $500 to $3,000 (national, retrieved 2026-10-24). Ask whether the glass is in stock or must be ordered. Custom sealed units are typically a one-to-three-week order for homes (EngineerFix, retrieved 2026-10-24), and no storefront lead time is published in the sources used here. None of these figures is a Madison quote, so get a written one.

What storefront and commercial glass repair covers
This page covers storefront window repair and commercial window replacement in four groups of work.
- Shop windows. Large front panes in a retail storefront, from a single cracked pane to a shattered one.
- Glass entry doors. Cracked or broken door glass, and doors that slam, drag or will not latch.
- Office windows. Windows in office suites and upper floors, including sealed double-pane units.
- Interior glass. Glass partition repair and office glass repair for partitions and other glass inside the building.
Emergency response for businesses: what the sources cover
Whether it was a break-in, a thrown object or a failed pane: before you send the form or call a glass company, photograph the damage and tell your insurer. Ask whether board-up, cleanup and a temporary cover are listed on the quote. No source we read covers securing the storefront until glass arrives, so ask the company what it does and what it charges, and get board-up prices and methods in writing.
- Ask the glass company what to do about any cracked upper pane, and what it charges.
- If a break-in is possible, file a police report. Triple-I advises one for theft, burglary or vandalism (Triple-I, homeowners claim guidance, retrieved 2026-10-24). A business should ask its own insurer what applies.
- Take photos and short video of the damage, the floor, and anything that was taken or hit, before you clean up.
- Protect the property from further damage. Triple-I's homeowners guidance tells policyholders to take reasonable steps to protect the property from further damage and to keep receipts.
- Notify your insurer or agent right away. Wisconsin's insurance regulator says not to throw out damaged property without the adjuster's agreement and to keep every repair receipt (OCI, storm guidance, retrieved 2026-10-24). Then send the quote form on this page or call to get a quote from a glass company.
Our page on emergency window repair and board-up covers the same steps for homes.
Storefront door repair: glass, closers, hinges and locks
When you send the form or call, say what the door does: slams, swings slowly, drags, will not latch or lock, rattles, or has a crack in the glass. Ask the company what the repair involves after it looks at the door on site, and get it in writing.
Door repair: what to tell the company and how customers get in
Madison averages 51.8 inches of snow a year (1991-2020 normals, Wisconsin State Climatology Office), so ask how soon a failed door can be made safe and usable. Tell the company what the door does and when it started. Ask whether one door can stay usable while the other is repaired, and settle that when you book. No sourced closer, pivot or hinge pricing was found, so ask the company to price each part separately on the quote.
Madison permits and review for storefront glass
Madison's rules do not give a simple yes or no for storefront glass, so check before you order.
- Windows, frames and doors. The City of Madison permit chart answers Yes to "Windows & Frames - replace," handled by Building Inspection, and Yes to "Door - replacement" (City of Madison, retrieved 2026-10-24).
- Glass-only and storefront work. The same chart has no row for glass-only replacement or storefront glazing. Contact Zoning staff with those questions. The chart does not say a glass-only swap is exempt.
- Commercial repairs. The city's non-residential Repairs & Replacements page lists windows and frames and doors under Building Permits. Its only dollar figure is "for general repairs over $500, contact Building Inspection." That page states no exemption, so ask Building Inspection before you start.
- Signs and street graphics. The chart says signs and street graphics need a permit through Zoning. Ask Zoning staff whether new lettering on your glass counts before you order it.
- Landmarks and historic districts. The Landmarks Commission reviews changes to the exterior appearance of a designated landmark or a building in a local historic district. A property is covered if its zoning carries a suffix such as HIS-L, HIS-UH or H. Check your parcel's zoning before ordering glass or a new door.
Replacing glass vs replacing damaged aluminum framing
Ask whether the quote covers the glass only or also the framing, stops, gaskets and door hardware. A quote should say whether the frame was inspected and what the price assumes. Settle in writing what happens to the price if frame damage shows once the old glass is out, and who approves it.
Process: send the form or call, on-site assessment, quote, scheduling around business hours
- Send the form or call. Say what broke, where it is and whether the opening is secure.
- On-site assessment. Ask the company to check and measure the glass, frame, hardware and access.
- Written quote. Get a commercial glass quote in writing. See the checklist below.
- Order or stock. Ask whether the glass is in stock or must be ordered, and for the date.
- Scheduling around business hours. Ask whether work can be set outside business hours and whether that changes the price.
- Installation and cleanup. Ask that the quote say whether it includes removal of the old glass and cleanup.
How long do large or tempered panes take?
The only lead-time figures stored are for residential custom sealed units, not storefront panes. EngineerFix says typically one to three weeks, and a Minnesota home inspector's blog reports about two weeks after on-site measurements (retrieved 2026-10-24). Confirm the date for your glass and whether a temporary cover stays on until it arrives.
Storefront glass repair cost
Storefront glass replacement cost and commercial glass repair cost depend on the quote. The sources below are national and mostly cover homes, so they set expectations, not a budget.
| Item | Range | Source and date |
|---|---|---|
| Large fixed panes in a storefront window (national) | $500 to $3,000 | Bob Vila, Window Glass Replacement Cost, retrieved 2026-10-24 |
| Storefront glass, material only (labor extra) | $500 to $3,000 | Fixr, Window Glass Replacement Cost, updated August 29, 2025, retrieved 2026-10-23 |
| Storefront glass, per square foot | About $5; tempered up to $25 | Bob Vila, retrieved 2026-10-24 |
| Tempered replacement, general window figure | $180 to $700 | Bob Vila, retrieved 2026-10-24 |
| Laminated replacement, general window figure | $275 to $625 | Bob Vila, retrieved 2026-10-24 |
| Glazier labor rate | About $50 to $75 per hour | Bob Vila, retrieved 2026-10-24 |
Fixr's figure is material only, so labor is extra. Per square foot, a 4 by 6 foot pane is 24 square feet, so the glass alone runs roughly $120 at $5 to $600 at $25, before labor, framing and delivery. That is arithmetic on Bob Vila's rates, not a quote.
Cost factors: pane size, glass type, framing, after-hours labor
- Pane size. Bob Vila prices storefront glass per square foot, so a larger pane costs more.
- Glass type. Tempered storefront glass runs up to $25 a square foot against about $5 for storefront glass (Bob Vila).
- Framing and hardware. Ask the company to price frame repair, gaskets and door hardware separately from the pane.
- Labor and hours. Glaziers charge about $50 to $75 an hour (Bob Vila). Work outside normal hours is a price to confirm.
Our window glass replacement page has national home-window prices that show how glass type changes cost.
Insurance for business glass
Should a business contact its insurer before calling a glass company?
Yes, notify your insurer early. The Wisconsin Office of the Commissioner of Insurance says to notify your agent or insurer right away, photograph the damage, not throw out damaged property without the adjuster's agreement, and keep all receipts for repairs or replacement (OCI, After a Storm Hits, retrieved 2026-10-24). Triple-I adds that you should ask how long you have to file and check your deductible (Triple-I, homeowners guidance, retrieved 2026-10-24). The OCI and Triple-I pages are storm and homeowner guidance, so a business should ask its own insurer what applies. Read your policy for the glass deductible. This page cannot say what your policy covers. For contractor offers after damage, OCI advises checking complaints with the state consumer protection hotline and not signing under pressure.
How to compare commercial glass quotes
Check what each quote leaves out. Each one should state:
- The glass type, thickness and number of panes.
- Whether the frame was inspected, and what happens if frame damage turns up.
- Who orders the glass and when it is expected.
- Whether the price includes removal of the old glass, cleanup and a temporary cover.
- Whether work outside normal hours costs more.
- Which services the price covers: panes, door glass, closers, locks or framing.
- Whether the permit or Zoning check above is the company's task or yours.
Ask for a certificate of insurance rather than taking the company's word for it.
Commercial glass types: tempered safety glass, laminated, insulated units, security film
Tempered, laminated and insulated glass may all appear on a storefront quote, and each does a different job.
| Glass type | What the sources say | Where it fits |
|---|---|---|
| Tempered | Gatsby Glass says it shatters into small, blunt pieces. Glass Doctor says it is strengthened glass widely used as safety glass. | High-traffic areas (Gatsby Glass) |
| Laminated | Gatsby Glass says it holds together when broken and adds security and sound insulation. Glass Doctor describes two layers bonded around a plastic interlayer. | Where you want the pane to hold together when broken, or less noise |
| Insulated glass unit | Gatsby Glass says double or triple glazed units insulate better and cut noise. The U.S. Department of Energy says the gap is filled with a gas such as argon or krypton and kept apart by spacers. | Where you want better insulation or less noise (Gatsby Glass) |
| Low-E coated | Glass Doctor says the transparent coating reflects sunlight to cut solar heat gain. | Where you want less solar heat gain (Glass Doctor) |
| Annealed | Glass Doctor says it breaks into large, sharp shards and is not suitable as safety glass. | Not suitable as safety glass, per Glass Doctor |
These are company and agency descriptions, not a spec for your building. Have the company write down the type, thickness, coating and gas fill it quotes for each pane.
Door glass and the federal safety glazing rule
The federal safety glazing standard, 16 CFR 1201, covers glazing in doors, storm and combination doors, shower and bathtub doors and enclosures, and patio-type sliding glass doors (eCFR). It exempts items such as wired glass in fire-rated assemblies and door openings a 3-inch sphere cannot pass. Under section 1201.2, a door with any glazing piece over 9 square feet is Category II, and a door where no piece is over 9 square feet is Category I. For a large glass entry door, ask the company which category your door's glass falls in. This is a federal product standard, separate from the building permit questions above.
Security film
Gatsby Glass says laminated glass holds together when broken and adds security. For a film applied to existing glass, ask for the paperwork behind any rating claim before you pay.
Seal failure and energy loss in commercial windows
An insulating glass unit is two or three panes held apart by spacers and hermetically sealed around the edge (Efficient Windows Collaborative glossary). A desiccant absorbs moisture inside the sealed space, and argon or krypton fills the gap to cut heat transfer.
Signs of a failed seal
StructureTech says a seal fails when the gas leaks out and humid air replaces it. Early on the window looks normal because the desiccant holds moisture for a while. Later, a quick outdoor temperature change can leave a small, temporary patch of condensation between the panes. Repeated evaporation leaves a thin mineral layer that makes the glass look permanently dirty. Fog between the panes on an office or storefront window is the sign to send the form or call, and our foggy window repair page covers it for homes.
Replace the unit, the sash or the whole window?
The same inspector lists three options: replace the whole window, replace only the sash, or replace only the insulated glass unit. He puts home sealed units at $300 to $700 for most windows and at least $250 for a small one, rising with size, spacer type and tempered glass (StructureTech, 2026 update, retrieved 2026-10-24). That is a Minnesota home figure, not a commercial one. He says most manufacturers give a 20-year warranty on the glass unit that does not cover labor, and that a covered seal usually means a replacement sash after you give the window's serial numbers.
How much energy does a failed seal cost?
The inspector calls a failed seal mostly cosmetic and says it does not by itself cause high energy bills. This is one opinion, not an energy figure for a commercial unit. DOE names the gas fill, spacers and low-E coating as what make a double or triple unit insulate.
Storefront glass repair FAQ
How much does storefront glass repair cost?
Bob Vila says the large fixed panes in a storefront window run $500 to $3,000 and labor $50 to $75 an hour (national). Fixr's $500 to $3,000 for storefront glass is material only (updated 2025-08-29). Get a written quote that lists what it includes.
Do I need a permit to replace storefront glass in Madison?
The city chart lists replacing windows and frames, handled by Building Inspection, and door replacement as permit items. It has no glass-only or storefront row and sends those questions to Zoning staff, so ask before you start.
Is a repair under $500 exempt from a permit?
The city's non-residential repairs page says to contact Building Inspection for general repairs over $500 and states no exemption. Ask Building Inspection whether your job needs a permit.
Does a Madison historic district change a storefront glass job?
It can. The Landmarks Commission reviews exterior changes on landmarks and in local historic districts. Check the parcel's zoning for a suffix such as HIS-L, HIS-UH or H.
Do I need a permit for a sign or lettering on my storefront?
The city chart says signs and street graphics need a permit through Zoning. It does not say whether lettering on glass counts, so ask Zoning staff before you order it.
Should a business contact its insurance before calling for storefront glass repair?
Yes, notify the insurer early. Wisconsin's insurance regulator says to notify right away, photograph the damage, keep damaged property until the adjuster agrees and keep every repair receipt.
Which glass is used where on a storefront?
Tempered suits high-traffic areas, laminated holds together when broken, and insulated units add insulation and noise reduction (Gatsby Glass). Annealed is not safety glass (Glass Doctor).
What does a 4 by 6 foot storefront pane cost in glass alone?
That pane is 24 square feet, so roughly $120 at $5 a square foot to $600 at $25 for tempered, before labor, framing and delivery. This is arithmetic on Bob Vila's rates.
What do Category I and Category II mean for a glass door?
Under 16 CFR 1201.2, a door with any glazing piece over 9 square feet is Category II. A door with no piece over 9 square feet is Category I.
Can a fogged office window be fixed without replacing the whole window?
A Minnesota inspector lists replacing only the sealed unit as one option, with most home units at $300 to $700. One inspector says a manufacturer warranty on the glass unit usually excludes labor.
