Broken commercial glass repair in Centennial, CO

Broken commercial glass usually needs to be replaced. A crack in annealed, tempered, or laminated glass cannot be brought back to its original strength, so the fix is a new lite plus repair of whatever the impact damaged around it: frame, gaskets, setting blocks, hardware. The first priority is making the opening safe and secure. The second is documenting the loss before the debris is gone. Element13 Facades is a commercial-only glazier serving Centennial and the Denver metro.
This page covers the broken-glass call specifically. It is one part of our wider glass repair service work.
Should I repair or replace broken commercial glass?
Replace it. Glass has no practical structural repair. A cracked lite can fail further with thermal movement, wind load, or a slammed door. Repair work applies to what surrounds the glass: gaskets, sealant, frame members, and door hardware.
Film can hold a cracked lite together for a short time, and security film can slow a break-in. Treat either as a temporary measure until the lite is replaced.
What causes commercial glass to break?
Knowing the cause matters because it decides whether the replacement will last. If the cause is still there, the new lite can break the same way.
Impact and vandalism
Thrown objects, vehicles, carts, and ladders cause most sudden breaks. Vandalism and attempted entry usually add frame and lock damage that is easy to miss from the sidewalk.
Thermal stress
Annealed glass breaks when the center heats while the edge stays cold. Shade from an overhang, a dark blind or film close to the glass, or a heating vent aimed at it can all set this up. Thermal cracks typically start at the edge and run in a curve.
Edge damage
A small chip from installation or from a prior service call can sit unnoticed for months, then crack under normal temperature swings. Tempered glass is especially unforgiving of edge damage.
Nickel sulfide inclusions
Rarely, fully tempered glass breaks spontaneously, with no impact. A nickel sulfide inclusion in the glass is the known cause. The break pattern often shows two small fragments shaped like butterfly wings at the origin. Other lites from the same production run may carry the same risk.
Hail and building movement
Hail breaks exposed glass and damages coatings and seals. Structural settlement or a racked frame can pinch a lite until it cracks without any visible impact.
What does a broken glass repair involve, step by step?
Every job differs, but commercial breakage work generally follows these stages. This describes the usual sequence in the trade, and the scope on a given building depends on site conditions.
- Arrival and make-safe. Loose and hanging glass comes out of the opening, and the area is cleared or barricaded. Shards in a frame pocket are a cut hazard for the next person who touches it.
- Board-up if the opening cannot be reglazed right away. Three-quarter-inch plywood is common. Polycarbonate keeps visibility when that matters for security or retail. Securing methods that avoid screwing into damaged framing, or furring on compromised framing, protect the frame for the final install.
- Photo documentation. Photos of the break, the frame, and the surrounding area support a claim and help identify the cause.
- Measure and identify the glass. Thickness, glass type, coatings, tint, spacer details on insulated units, and frame condition all get recorded. Matching a tinted or reflective lite to neighboring glass takes care, and slight variation between production runs is possible.
- Frame and hardware assessment. Pressure plates, glazing stops, gaskets, setting blocks, weeps, and sill flashing get checked for damage. On doors, closers, hinges, locks, pivots, and weatherstripping are checked along with alignment.
- Fabrication. Stock sizes can move quickly. Custom sizes, tempering, laminating, and insulated low-E units take longer.
- Permanent installation. New glass is set on proper setting blocks, secured with gaskets or sealant suited to the system, and the weep and drainage path is confirmed open.
How long does it take to replace broken storefront glass?
A stock-size, single-pane lite can sometimes be replaced within days of measuring. Custom, laminated, or insulated low-E glass takes longer, and custom frame finishes can add more. Board-up usually covers the gap in the meantime.
These factors set the timeline:
- Stock versus custom size. Standard sizes may be on hand or quick to cut. Odd sizes get fabricated.
- Glass type. Annealed is the quickest. Tempered adds a heat-treating step. Laminated with a PVB or SGP interlayer and insulated units with low-E coatings take longer still.
- Heat soaking. Where specified for tempered glass, it adds time to the fabrication stage.
- Frame finish. If a frame member needs replacing, anodized or Kynar finishes have to be matched or ordered.
- Access. Upper floors, lifts, and sidewalk or lane closures add scheduling steps.
We give a schedule once the glass type and frame condition are confirmed, and we flag lead-time risks early so you can plan around them.
How much does commercial glass replacement cost?
Price per panel depends on glass type and size, access, timing, and what the frame needs. We do not quote numbers without seeing the opening, because the spread between a small annealed lite and a large laminated insulated unit is wide.
The main cost drivers:
- Glass type, size, and thickness
- Coatings, tint, and insulated construction
- Lifts, scaffolding, or traffic control for access
- After-hours work and emergency response premiums
- Frame, gasket, and hardware repair found during the work
- Board-up before permanent glass goes in
If you are comparing quotes, confirm each one covers the same glass spec, frame repair, board-up, and disposal.
Should I call my insurance before a glass company?
Call your carrier early, but do not leave the building open while you wait. Many property policies expect you to take reasonable steps to protect the property, and board-up costs may be reimbursable as mitigation expense. Check your policy and speak with your broker or carrier.
A few practical points:
- Photograph the damage before cleanup.
- Keep invoices for make-safe and board-up work.
- Check whether a wind and hail deductible applies, since it can differ from the standard deductible.
- Compare the deductible to the cost of the repair. A small break may cost less than the deductible.
- Ask whether the carrier needs to approve the glass contractor or accepts direct invoicing.
We do not determine coverage. We can supply documentation and itemized scope to support your claim.
Who pays for broken glass in a leased space?
The lease decides. Many commercial leases put interior glass and storefront glass on the tenant, and structure and building envelope on the landlord, but the wording varies a lot. Read the maintenance, repair, and insurance clauses, and check whether the landlord carries glass coverage.
Property managers can save time by confirming responsibility before work is authorized, and by telling the glazier who the approving party is. Disputes over who owns the loss are a common reason a broken opening stays boarded for weeks.
Can I stay open during the repair?
Usually yes, with planning. Broken glass work can often be phased so one opening is closed at a time, with barriers or temporary protection keeping customers and staff clear.
Options that keep operations running include:
- Doing the work after hours, early mornings, or during slow periods
- Using a polycarbonate board-up when visibility or daylight matters
- Scheduling around deliveries and peak traffic
- Giving tenants notice of the work window and any entrance changes
- For healthcare spaces, discussing privacy and dust or debris control before the work begins
Entrance doors need special care. If the broken lite is in the main entry, a secondary entrance may need to be designated for the duration.
What should the replacement glass be?
Match the original unless there is a reason to change it, and check the code. Safety glazing under IBC Chapter 24 and the CPSC 16 CFR 1201 and ANSI Z97.1 standards generally applies in hazardous locations such as doors and glass near doors. ADA entrance requirements affect door hardware and clearances, which matters if the door needs adjustment during the repair.
Breakage is also a good moment to reconsider specs:
- Laminated glass holds together when cracked and resists forced entry better than monolithic glass.
- Tempered glass is stronger than annealed and breaks into small pieces.
- Insulated low-E units carry U-factor and SHGC ratings. IECC and ASHRAE 90.1 may govern the spec, depending on the scope of work.
- Security options include laminated security glass, anti-shatter film, and impact-resistant glazing for locations with repeat break-ins.
How long do commercial insulated glass units last?
There is no single number. Service life depends on the quality of the primary seal, secondary seal, spacer type, orientation, and thermal exposure. Seal failure, desiccant saturation, solar pumping, and thermal cycling all shorten it.
Signs of failure include fogging between panes, mineral deposits, and bowing or distortion. Gas loss is not visible, but it reduces performance. Manufacturer glass warranties and IGU seal warranties typically cover seal failure but exclude thermal breakage and impact. Read the terms. If a unit has failed rather than broken, see our IGU replacement page.
When is broken glass really a frame or leak problem?
Sometimes the broken lite is the symptom. A lite that keeps cracking at the same corner may point to a racked frame, a shifted mullion, or pressure on the glass from building movement. Water stains below a recent break can mean the problem was never the glass alone.
A good diagnosis looks at the framing as well as the lite. Failed gaskets, perimeter silicone, blocked weeps, and loose pressure plates can all let water in or put stress on glass. Where water is involved, glass leak repair addresses the cause. For framing and door work around the opening, see our storefront glass repair service.

Frequently Asked Questions
No, not structurally. Glass cannot be restored once cracked. Film or temporary measures can hold it together briefly, and the lite should be replaced. Frame, gasket, and hardware damage around the glass can usually be repaired.
Common causes are edge damage, thermal stress, building movement, and, rarely, a nickel sulfide inclusion in the glass. Inspecting the break pattern and the frame helps identify the cause so the replacement does not fail the same way.
It depends on the cause. If the break came from impact, the neighbors are typically fine. If it came from nickel sulfide or a frame problem, adjacent glass may share the risk and deserves an inspection.
A close match is usually possible, but production runs can vary slightly. Bring this up early, especially on elevations where the new lite will sit next to old ones.
The lease controls it. Many leases assign storefront glass to the tenant, but wording varies, and the landlord's or tenant's insurance may apply. Confirm responsibility and the approving party before authorizing work.

When Glass Door Problems Can't Wait Contact Element13
Your building's glass front entrance doors handle hundreds of entries daily. When they fail, have cracked glass, broken closers, or hardware that won't engage, it's not just inconvenient, it's a security risk. Property managers and general contractors know that entrance problems reflect poorly on the entire building and create liability concerns.
