Window & Door Repair Company
The crank spins but the sash won’t open. The lock won’t latch. The slider sticks or jumps the track. Most of the time that is window hardware repair — not a new window.
WindowServ repairs and replaces operators, locks, rollers, hinges and handles across New Jersey. Send a photo of the problem. We tell you what part failed and what it takes to fix it.
Name, phone, ZIP, and a photo of the window. We reply the same day.

If any of these sound familiar, the fix is usually the mechanism — not the whole unit. That is the point of window hardware repair near me: restore the sash you already have.
Looking for all window repair services — glass, rot, balances, and hardware — start at window repair.
Casement window repair almost always starts at the operator. Gears wear flat. Arms bend. The splined stud that holds the crank handle rounds off. People force a frozen sash in winter and finish the job the ice started.
We do window crank repair the way a shop does it: identify the operator style, match the arm length and gear set, and replace what failed. Sometimes that is only the crank handle. Often it is a full casement window operator replacement. Awning windows use the same family of operators — same diagnosis, different mounting.
This is the call we get most for casement window crank repair. The handle turns because the gear teeth or the splined stud are gone — the arm never gets the torque. We replace the worn piece, not the whole window, and test open/close before we leave.
Need window crank repair near me for a brand that no longer sells parts? Send a clear photo of the operator and the handle. We source a compatible unit or adapt a modern operator that fits the sash weight.
Casement and awning operators look simple from the room. Inside, the gear set and arm decide whether the sash moves at all.
Window lock repair is about two jobs at once: keeping the sash shut and pulling it into the weatherstrip. A lock that won’t latch leaves a gap. Cold air comes in. The sash rattles in wind.
We repair and replace casement multipoint locks and cam handles, double-hung sash locks, and sliding-window latches and keepers. Window latch repair is usually a worn cam, a bent keeper, or a sash that no longer lines up with the strike — we correct the part and the alignment so the lock seats cleanly.
This is not locksmith work. We don’t rekey cylinders or open locked doors. We fix the window mechanism so the sash closes and latches the way it was built to. If you need window lock repair near me after a failed DIY handle swap, bring the old part or a photo — brand and year matter.
Sliding window repair is almost always rollers, track, or both. The sash should roll, not grind. When plastic wheels flat-spot or bearings seize, you feel every inch of travel — and the sash starts to drop and scrape the frame.
Worn or broken rollers make the sash drag, squeak, and jump. Sliding window roller replacement restores smooth travel when the track itself is still true. We match roller diameter, axle style, and housing so the sash sits level again.

Dirt, bends, and cracked vinyl rails stop even good rollers. Sliding window track repair often starts with cleaning and straightening. If the rail is cracked or crushed, we replace the damaged section instead of forcing the sash.

We diagnose rollers versus track on the visit. Many jobs need both: new rollers and a cleaned or repaired rail. You get one scope, not a guess from a parts catalog.
Book help →Casement friction hinges and stay arms hold the sash in place as it swings. When they wear, the sash sags, catches the frame, and won’t close square. Window hinge repair — or window hinge replacement when the arm is bent — brings the sash back into the plane of the frame.
Loose or broken handles are window handle repair in the simplest sense: new grip, new set screw, or a full handle matched to the operator stud. If hinge screws spin freely because the wood under them is soft, that is no longer hardware — the sash needs wood rot repair before new screws will hold.
Almost always we replace the failed part — window hardware replacement — and leave the frame alone. A full window only makes sense when the sash or frame itself is rotten or bent out of square.
| Problem | Usually fixed by | When the whole window needs work |
|---|---|---|
| Crank spins | New handle or operator | Sash rails are broken or the frame is twisted |
| Window won’t lock | Lock, latch, or keeper | Sash no longer sits in the opening |
| Slider sticks | Rollers and/or track cleaning | Frame is crushed or bowed |
| Sash sags | Hinges / stay arms | Wood around hinge screws is rotten |
| Drafts when closed | Lock plus weatherstripping | Sash is warped and won’t seal |
| Screws won’t hold | Wood rot repair first | If rot is through the sash — sash replacement |
If a double-hung or single-hung sash drops when you let go, that is a balance — not a crank, lock, or roller. We keep that work on its own page so you get the right parts and the right process. See window balance replacement and repair.
We repair hardware on casement, awning, sliding, double-hung, and single-hung windows — including casement window repair near me jobs where the brand label is gone. Don’t know the make? Send a photo of the operator, lock, or roller. We’ll match the part.
Brand names show compatibility. WindowServ is independent and is not affiliated with or endorsed by these manufacturers.
You can buy a crank or roller online. Fitting the right one is the hard part.
We won’t walk you through screw counts or DIY steps here. If you already tried a kit and the sash still won’t move, send the photo — we’ll finish the repair.
You send a picture or describe the symptom. We narrow the part before the visit.
We confirm the failed hardware, check alignment, and quote the fix before work starts.
We fit the matched operator, lock, roller, hinge, or handle. Same-visit installs when the part is on the truck.
Open, close, latch, and weatherstrip contact — we don’t leave until the sash works.
Every opening is different, so we quote from the photo and confirm on site. These are the factors that move the number:
Real jobs on New Jersey homes — operators, hinges, and mechanisms restored so the original sash stays in place.
If the frame is sound, we fix the hardware and leave the unit you paid for in the wall.
Operators, locks, rollers, and hinges are consumable. The sash and trim are not.

In the large majority of cases, just the glass. The frame and sash are structural; the glass is a consumable part that sits inside them. Unless the wood is rotted through or the frame has shifted out of square, replacing the pane restores the window completely — for roughly 80% less than a full replacement.
Look for a small etched stamp — usually called a bug — in one corner of the pane. It names the manufacturer and the safety standard. If the glass is already shattered, the break pattern tells us: tempered glass crumbles into small blunt pebbles, ordinary annealed glass breaks into long sharp shards. Our technician checks either way before quoting.
Single pane glass goes in within a week. A double pane insulated unit takes one to two weeks, because the unit is manufactured to the exact size of your opening and then shipped. Your estimate comes back the same day you send a photo.
Clear the loose glass wearing heavy gloves and wrap it before disposal. Cover the opening from the inside with something rigid — plywood or heavy cardboard backed by a board — and tape the perimeter. Plastic sheeting on its own keeps rain out but nothing else. Tell us if the opening is at ground level or street-facing and we'll prioritise the visit.
Usually, yes. We match thickness, tint, coating and — where it exists — the obscure or patterned texture. On very old houses the original wavy glass can't be reproduced exactly; in those cases we'll show you the closest available option and let you decide before anything is ordered.
Yes. Door glass is almost always tempered by code, and the units are heavier than window glass, so it's a two-person job. See patio door glass replacement for that specifically.
We repair it before the new glass goes in. Putting a new pane into a rotted or out-of-square sash guarantees you'll be calling someone again within a season. If the damage is extensive we'll quote the repair separately so you can see exactly what you're paying for.
Yes — storefronts, offices and multi-unit buildings across northern New Jersey. Commercial work has its own code requirements and access constraints, so it's quoted separately. See our windows services or broken glass replacement.
