Window & Door Repair Company
The sash won’t open. Cold air sneaks past the lock. The glass is cracked, fogged, or the frame is soft. Most of the time that is a window repair job — not a full replacement.
WindowServ fixes residential windows across New Jersey: stuck hardware, drafts, failed seals, broken glass, and rotted wood. Send a photo. We tell you what can stay and what has to change.
Name, phone, ZIP, and a photo of the window. We reply the same day.

If the frame and sash are still sound, we repair the failed part and leave the window you already own in the wall. That is usually faster, cleaner, and far less expensive than tearing out a working unit because one seal, pane, or lock failed. On New Jersey houses from the 1980s–2000s — and older wood stock — the profile and trim are hard to match with a stock replacement, so full replacement stays the backup plan, not the opening pitch.
These are the calls we get most for home openings that still deserve a fix. Each one has a symptom, a likely cause, and a clear repair path.
The sash binds, the crank spins without moving the window, or the lock will not latch. That is usually window lock repair or worn operators — not a new window. When the sash itself is damaged, we look at window sash repair next.

Cold air at the lock, rain staining the sill, or condensation along the stop usually points to window seal repair. We replace failed weatherstripping and glazing seals, repair leaking window edges at the sash line, and stop repeat window leak repair callbacks when the frame is still true. Window seal repairs are often the difference between a drafty room and a window that still has years left.
Haze or moisture between the panes means the insulated glass unit seal failed — air and vapor enter the space that should stay dry. You cannot wipe that fog away from the living room side, and temporary “defogging” does not restore the seal. We replace the sealed unit and keep the sash when the frame is sound. See broken glass replacement when the glass itself is cracked or shattered.
Soft sills, peeling paint that hides wet wood, or a corner that crumbles under a screwdriver need window frame repair before new glass or hardware will hold. We cut out rot, sister sound stock, and refinish when a section can be saved. When the frame is gone, window frame replacement is the honest call — not another patch. Deep wood damage is covered on our wood rot repair page.
If you need to fix a broken window after impact, a stress crack, or a failed pane, clear loose shards safely and cover the opening. Broken window repair on a home almost always means replacing the glass in the sash, checking the frame, and resealing the perimeter — not ordering a whole new unit. We handle repairing a broken window on site when the sash is sound: single panes, broken window replacement of insulated units when the IGU failed, and work to fix a cracked window before drafts and water follow. For glass types and photo estimates, use our broken glass replacement hub.
Glass out, frame sound — the usual path for broken home window repair on residential openings.
This page is the hub for window repair services. Pick the card that matches your failure and open the focused page for that job.
Split rails, failed joints, or a sash that no longer squares in the frame. We repair when wood and joints allow; otherwise we build or fit a replacement sash.
Window sash replacement →Cranks that spin, locks that won't latch, sliders that stick. We repair and replace window hardware so you keep the window you have.
Window hardware repair →Rotted sills, jambs, and sash corners. Cut out the bad wood, rebuild the section, and protect the repair so glass and hardware have a solid seat.
Wood rot repair →Single pane, insulated units, tempered and specialty glass. Frame stays; only the glass changes when the sash is sound.
Broken glass replacement →Fog between panes means the IGU seal failed. We replace the sealed unit rather than clearing moisture that will return.
Double-pane seal repair →Double-hung sash that will not stay open, or that drops hard, usually needs balances or springs — not a new window.
Window balance repair →Older wood windows worth keeping: careful repair, glazing, and hardware so the house keeps its original openings.
Window restoration →We work on double-hung, casement, sliding, awning, and basement openings in wood, vinyl, and aluminum. Vinyl window repair is usually hardware, rollers, or sealed glass. Wood window repair often adds glazing and rot work. Casement window repair almost always starts at the operator. Awning window repair and basement window repair follow the same rule: fix the failed part when the frame still holds.
Brand-compatible parts when the mark is still readable — including Marvin window repair on older units, plus Andersen, Pella, Milgard, Jeld-Wen, Simonton, PGT, Ply Gem, Weather Shield, and Silverline. We are an independent shop, not a dealer for any manufacturer.
If the frame and sash are structurally sound, window repair and replacement are not equal options — repair almost always wins on cost, mess, and how the house looks afterward. Replacement makes sense when rot is structural, the opening is out of square beyond correction, or repeated failures mean the unit is at end of life. For those jobs see window replacement.
| Factor | Window Repair | Full Window Replacement |
|---|---|---|
| Cost | Parts and labor for the failed component | Full unit, trim, and often exterior finish work |
| Time on site | Usually hours, not days | Longer — demo, set, seal, and finish |
| Mess | Localized to the opening | Demo dust, trim removal, exterior touch-up |
| What stays | Original frame, sash profile, and interior trim | New unit; profiles and trim often change |
| When it makes sense | Sound frame; failed glass, seal, hardware, or limited rot | Structural failure, chronic leaks, or openings past repair |
Window repair cost depends on the failure, not a single catalog price. Window repair price moves with glass type, brand-specific hardware, access, and how many openings share one visit. Broken window repair cost and the cost to fix broken window are driven by pane size and safety glazing. Leaking window repair cost rises when rot or out-of-square frames have to be corrected first.
Four clear steps so you know the scope before we start cutting or ordering parts. Most residential visits stay on site; when a sash has to leave for shop work, we say so up front and schedule the return install.
You send pictures of the opening and the failed part. We name the likely repair and what we need to confirm on site.
We check the frame, sash, and operation. If the job changed from the photo, we say so before work begins.
Parts fitted, glass set, seals replaced, or wood rebuilt — then operation and latch tested with you present when possible.
Opening cleaned, debris removed, and a plain-language summary of what was done and what to watch for.
Real residential jobs — sash, wood frame, and multi-pane openings restored so the house keeps its original windows.
Shattered panes and a failed sash — rebuilt and reglazed so the opening stays original.
Soft wood and broken glass cut out — frame rebuilt for a lasting repair instead of a full window swap.
Failed insulated glass and mist between panes — sealed unit replaced so the window looks clear again without a full frame swap.
Homeowners call us when they want the opening fixed — not a sales visit for a whole new window. Four reasons people stay with WindowServ after the first job.
We are a window repair company first. If the frame is sound, we fix the failure and leave the unit in place.
Photo review first, then on-site confirmation. If replacement is the only sane option, we say so and explain why.
Glass, seals, and hardware are consumable. Keeping original frames protects the look of older houses after house window repair.
Glass, wood, and hardware on the same visit when the job needs it — one window repair contractor for the full opening, not a handoff chain.

It depends on the failure: hardware, glass, seals, or wood each use different parts and time. Access, brand-specific pieces, and how many openings share one visit also move the number. We quote from your photo and confirm on site — we do not publish a single catalog price.
If the frame and sash are structurally sound, repair is almost always the better first step. Replacement makes sense when rot is structural, the opening is badly out of square, or the unit fails repeatedly. We say so plainly when repair would only postpone the real job.
The fog between panes means the insulated unit seal failed. You cannot permanently clear that moisture from the room side. We replace the sealed glass unit and keep the sash when the wood or vinyl is still sound.
Timing depends on glass type. Many single-pane jobs finish within a week after measure. Insulated units are built to size, so fabrication and shipping set a longer timeline. Your photo estimate comes back the same day with a realistic schedule.
Yes. A sash that will not open or latch is usually hardware — operators, locks, rollers, or hinges — covered on our window hardware repair page. A double-hung that will not stay open is often a balance or spring issue; tell us in the photo notes and we diagnose on site.
Yes. Soft sills and jambs get cut back and rebuilt when enough sound wood remains. Extensive rot is scoped on our wood rot repair page. If the frame cannot carry glass or hardware safely, we recommend replacement instead of another patch.
