Window Repair in New Jersey
Broken glass, foggy panes, stuck sashes, dead balances, rotted sills — every window failure is a component failure, and every component can be fixed. That's our whole trade, at about 80% less than replacement.

Broken or cracked glass
A ball, a branch, a slammed sash. We replace the glass — not the window.
Window glass replacement →Fog or haze between panes
Condensation trapped inside a double pane means the seal failed. The glass unit swaps out.
Foggy glass replacement →Window won't stay open
A sash that slams shut or won't lift has a broken balance or spring — a hardware part, not a window problem.
Balance repair →Sash stuck, loose, or rattling
Racked corners, swollen rails, failed cords. The moving part of the window is rebuildable.
Sash repair →Soft or rotted wood
A spongy sill or crumbling frame corner is fungal decay — local, mappable, and repairable in place.
Rotten frame repair →Cracked, missing glazing putty
When the putty line fails, water reaches the wood. Reglazing seals the sash before rot starts.

Searching "window repair near me"
shouldn't end in a replacement pitch.
Try it and see what comes back: window replacement companies. That's not an accident — the industry earns on new units, so nearly every "window repair company" in New Jersey routes your service call into a sales appointment. The technician glances at a failed balance or a fogged pane, shakes his head, and the quote that lands on your kitchen counter is for new windows. We built RotGone on the opposite premise: a window is a system of parts — glass, sash, hardware, glazing, and the wood frame around them — and the honest response to one failed part is to repair that part.
The story we hear most often goes like this: a homeowner was told the entire window needed replacement — and we fixed the sash. One component, one visit, one small fraction of the replacement quote. Multiply that across the broken window repair calls, the foggy-glass calls, and the "it won't stay open" calls we take every week, and you have the reason our Google rating sits at 5.0: not marketing, just the repeated experience of paying for a repair after being quoted a replacement.
House window repair, by component
Glass. A cracked single pane is cut and set the traditional way, bedded in fresh glazing. A broken or foggy double pane means the sealed glass unit — the IGU — is replaced while the sash and frame stay put. Either way, glass replacement is a glass job, not a window job.
Sash. The moving part of the window racks loose at the corners, swells shut in humid summers, and drops when cords or balances fail. Sash repair rebuilds joints, planes binding edges, and re-hangs the sash so it glides and locks. Rot in a rail or stile is cut out and rebuilt — see wood window repair for the full craft.
Hardware. Locks, lifts, cranks, and the spring balances hidden in the jambs do the mechanical work of the window, and they wear out decades before the window does. We free, adjust, adapt, or source replacements — including for long-discontinued lines.
Wood. Soft sills, crumbling frame corners, peeling paint that never stays fixed — that's fungal decay, and it's the most needlessly replaced category of all. Our rotten frame repair and the wider wood rot repair practice rebuild decayed sections in place with conservation-grade epoxy and spliced-in matching wood.
Glazing. The putty line holding the glass is a wear item. Reglazing renews it before water gets behind the glass and starts the rot cycle — the cheapest window repair there is, and the one that prevents the most expensive.
What does window repair cost?
Honest answer: it depends on the component, but the range has a shape. Hardware and adjustment work sits at the bottom of the scale — typically a single-visit job priced in the low hundreds. Glass and sash repairs occupy the middle. Structural rot repair to a frame or sill is the most involved — yet even there, the bill is measured in hundreds, not thousands. Now hold that against the alternative: one quality replacement window runs well into four figures installed, and whole-house window replacement projects in our area start around $23,000. Across all categories, repair lands at roughly 80% less than replacing the unit — which is why every RotGone estimate prints both numbers side by side. You see the window repair cost and the replacement cost for the same opening, and the decision is yours, made with the math in front of you.
Broken window right now? Start with safety
A shattered pane is the one window problem that can't wait for a convenient week. If glass is broken out of the frame, clear the immediate area, leave the shards in the sash for us rather than pulling them, and send the photo — broken window repair calls get triaged first. On the assessment visit we secure the opening so the house is weathertight and lockable while replacement glass is cut or a sealed unit is manufactured. Nobody sleeps next to an open hole, and nothing about the emergency changes the economics: it's still a glass repair, not a window purchase.
One repair company, from Montclair to Westfield
"Near me" matters in this trade because windows fail by region: the pre-war double-hungs of Montclair, Glen Ridge, and Millburn fail at cords, putty, and sills; the 1960s–90s stock in Livingston, Wayne, and West Caldwell fails at balances and sealed glass; the larger homes of Summit, Chatham, and Westfield mix both. Working the same towns for 8+ years means we usually know what's wrong with your window before the truck leaves the shop — and the truck doesn't travel far, because the shop is in West Caldwell.
Same-week service, built into the process
Text a photo of the problem and you'll have an answer the same day — what failed, whether it's repairable, and a realistic range. Onsite assessment follows within 1–2 days. Most repairs finish within 1–2 weeks of approval, and single-component jobs are often done the same week you first called. Compare that with a replacement order: weeks of factory lead time, a demolition day, and interior patching after. We work Mon–Fri 8:00 AM – 6:00 PM, we're fully insured, and every repair carries our 5-year workmanship warranty.

The questions every homeowner asks
before the first call.
Do you handle house window repair, or only certain window types?
All of it — that's what makes this page the umbrella. Double-hung, casement, awning, slider, picture, bay, and basement windows; wood, vinyl, aluminum, and clad frames; modern brands and pre-war originals with no brand at all. Because we repair at the component level, the window type matters less than which part failed: glass, sash, hardware, or wood. If you're not sure what you have, text a photo to (973) 564-0958 and you'll have an answer the same day.
How fast can you repair a broken window?
Photo answer the same day, onsite assessment within 1–2 days, and nearly every repair completed within 1–2 weeks of approval — many the same week. Hardware and adjustment work is usually a single visit. Glass replacement waits only on the glass itself: single panes cut quickly, while insulated units are custom-ordered to size. If the opening is unsafe in the meantime, we secure it so your home is weathertight and locked while parts are on the way.
How much does window repair cost in NJ?
Almost always a fraction of replacement — the pattern across our work is roughly 80% less than swapping the unit. Hardware repairs sit at the low end, glass and sash work in the middle, and structural rot repair at the top — yet even that tops out far below the four-figure cost of a single installed replacement window, let alone the $23,000+ that whole-house projects run in our area. Every written estimate shows the repair number next to a realistic replacement number for the same opening, so you decide with both figures visible. The photo answer and the estimate are free.
Is it worth repairing an old window instead of replacing it?
Usually, yes — and the older the window, the stronger the case. Pre-war windows in towns like Montclair, Glen Ridge, and Summit were milled from dense old-growth wood and built to be serviced: every part comes out, and every part can be repaired or replicated. A repaired original with renewed glazing and weatherstripping performs far better than its reputation, keeps the proportions a replacement flattens, and carries our 5-year workmanship warranty just like new work. When a window genuinely is past saving, we say so in writing — replacement is our last resort, not our sales pitch.
What should I look for in a window repair company?
Three things. First, that repair is actually their trade — many "repair" listings are replacement salesmen who quote new windows at every visit. Second, insurance: RotGone is fully insured, with general liability and workers' compensation coverage. Third, a warranty in writing — ours is a 5-year workmanship warranty on every repair. Add a public track record (our Google rating stands at 5.0) and a process that starts with a free photo diagnosis rather than an in-home sales appointment, and you have the checklist we built this company against.
