Window Glass Replacement
A broken pane is the most over-treated problem in home repair: the glass failed, and the industry quotes the whole window. We replace the glass — single panes and insulated units — in the frame you already own.

You need new glass.
Somewhere along the way, American homeowners were taught that glass and window are the same word — so when a pane cracks, they search for window companies, and window companies sell them windows. Step back and the logic collapses. The frame is fine. The sash is fine. The locks, the balances, the trim, the paint — fine. One sheet of glass failed, and glass is a replaceable part, the way a windshield is a replaceable part of a car. Home window glass replacement is the exact service the situation calls for, and it's the service almost nobody in New Jersey leads with. We do.
The economics explain the silence. Glass window replacement — the honest, glass-only kind — is a modest ticket. A new window is a four-figure ticket per opening. Guess which one the industry built its sales process around. Our process runs the other direction: photo first, glass-only diagnosis the same day, and a written price that covers the pane, not the wall around it.
The routing decision: single pane or sealed unit
Every glass job starts with one question — what kind of glass is in the sash? Single-pane windows, standard in homes built before the 1980s and in most storm sash, hold one sheet bedded in glazing putty. Replacement is classic glazier's work: the broken glass comes out, the opening is cleaned and primed, new glass is cut to size, set, pointed, and puttied to a crisp sightline. Double-pane windows hold a sealed insulated glass unit — two sheets, a spacer, and a desiccant-filled edge seal, working as one factory-made part. When either sheet breaks (or the seal fails and the unit fogs), the whole sealed unit is replaced as a cartridge: measured exactly, custom-made, and set back into your existing sash. The deep dive on that part lives on our insulated glass unit page; if yours is cracked rather than cloudy, the double pane repair page walks through the decision.
Where glass-only service applies
- Broken or cracked panes — from impacts, thermal stress, or slammed sashes
- Fogged double panes — failed seals with condensation trapped inside
- Patio and French door glass — including large tempered units
- Basement, garage, and storm-sash panes — the small jobs most companies won't schedule
- Safety upgrades — tempered glass where current practice calls for it
The one thing we check before quoting glass: the condition of the wood holding it. Glass set into a rotted or failing sash won't stay sealed, so if we find soft wood we'll show you, price the sash repair honestly, and do both in one mobilization. That's the difference between a glass vendor and a window repair company.
The cost, framed honestly
Window glass replacement cost follows the glass: size, thickness, temper, and whether it's a single sheet or a manufactured sealed unit. Single panes are a low-hundreds repair. Sealed units cost more but remain a small fraction of the replacement window they save — in line with the 80%-less pattern across our services. There is no trip-fee ambush and no in-home sales pitch: the photo answer is free, the measurement visit is free, and the estimate shows glass-only against full replacement so the comparison is yours to make. Backed by our 5-year workmanship warranty, a fully insured crew, and a 5.0 Google rating.

What homeowners ask when
the ball comes through the window.
Can you really replace just the glass in my window?
In almost every case, yes. Glass is a serviceable part, held in the sash by glazing putty and stops on older windows or by a gasketed channel on modern ones. We remove the broken pane or the sealed unit, prepare the opening, and set new glass in place — the sash, frame, hardware, and trim never move. The exceptions are rare: a sash so deteriorated it can't hold glass safely, which is a sash repair conversation, not a reason to buy a window.
How much does window glass replacement cost?
It scales with the glass, not the window. A single pane is the least expensive — glass cut to size plus glazing labor, priced in the low hundreds. An insulated (double-pane) unit costs more because the sealed unit is custom-manufactured to your exact dimensions, but it still lands far below the four-figure cost of a replacement window for that opening — the roughly 80% savings that runs through all our work. Your estimate shows the glass-only price against the replacement price, in writing, free.
How long does glass replacement take?
Photo answer the same day; onsite measurement within 1–2 days. Single panes are quick — often repaired on the first working visit. Insulated units are ordered to size and installed on arrival, with the whole job typically complete within 1–2 weeks. If the window is shattered, we secure the opening so your home stays weathertight and safe while the glass is made.
Will the new glass match my other windows?
That's part of the measurement visit. We match thickness, tint, and — for insulated units — the spacer profile and coatings, so the repaired window reads identically to its neighbors. For older homes we can set glass in traditional putty with the same sightlines the sash was built for; see window reglazing for how that craft works.
The glass isn't broken, just foggy. Same service?
Same family, different page. Fog between panes means the sealed unit's edge seal failed and moisture got inside — the glass is intact but the unit is dead. The fix is still glass-only: the insulated unit swaps out while the window stays. The full explanation lives on our foggy window glass replacement page.
Every way glass fails —
and gets fixed.
