Window Hardware Repair
Window hardware repair fixes a crank that spins, a lock that won’t catch or a sash that won’t stay up — part failures, not window failures. We replace the part and get the window working and secure again.

Signs You Need Window Hardware Repair
Crank & Operator Repair
The crank mechanism on casement and awning windows. When the gears strip, the handle spins freely, feels stiff, or grinds — and the window won't open or close. We replace the operator and restore smooth cranking.
Balancer Repair
The spring balance that holds a single- or double-hung sash open. When it wears out, the window drops shut or is hard to lift. We replace worn balances — usually in pairs — so the sash glides and holds again.
Latch Repair
Tilt latches, sweep latches, and cam latches that no longer hold, align, or release. We repair or replace the latch and its keeper so the window closes tight and — on tilt-in windows — tilts and locks back into place correctly.
Lock Repair
Locks that won't engage, won't line up, or have broken. We repair or replace the lock and keeper and realign them so the window secures firmly — a comfort issue and a security one.
Which Part Failed?
Match the symptom to the part — these are the ones that wear out:
- Sash lock — pulls the two sashes together at the meeting rail.
- Tilt latches — let the lower sash tilt in for cleaning; brittle plastic ones snap in the cold.
- Balance — hidden in the side channel; holds the sash up.
- Pivot shoe — connects the balance to the sash at the bottom of the channel.
- Crank operator — the gearbox and handle that open a casement; stripped gears are the usual failure.
- Hinges & tracks — let the casement swing; worn hinges make it sag and drag.
- Multi-point lock — pulls the casement tight against the weatherstripping.
Every part shown is replaceable on its own — the window stays.
Each part is replaced on its own; a photo of it (and any label on the frame) lets us order the right one.
- Photograph the part (and any label on the window frame) so we can identify it.
Four Window Hardware Problems We Fix Every Week
A window can be in perfect shape — solid frame, clear glass, sound wood — and still be useless because one small piece of hardware has worn out. The good news is that hardware is meant to be replaced.
Cranks, operators, balances, latches, locks, hinges, and keepers are all serviceable parts. When one fails, the fix is to repair or replace that component — not the window.
That keeps a hardware repair among the most affordable window services there is, and it applies across every window type: casements with crank operators, double- and single-hung windows with balances, and every window that latches and locks.
Below are the four hardware problems we handle most often. If your window's issue isn't listed, it's almost certainly still a hardware fix — call and describe what it's doing.
Most window hardware repair comes down to a handful of parts: window cranks and operators, window locks and keepers, window latches, tilt latches and balances.
We source and install replacement window parts, identify brand-specific parts from a photo, and source proven equivalents for discontinued window parts — so "they don't make that part anymore" rarely means you need a new window.

How We Repair Window Cranks, Locks & Latches
Identify the part
We match the brand, model and part — from a photo in many cases — including discontinued hardware.
Source the right fit
We use the original part where it exists, and proven aftermarket or universal equivalents where it doesn't.
Replace & adjust
The part is installed and adjusted so the window cranks, locks or balances smoothly.
Test it
We open, close and lock the window several times before we leave. If we installed it wrong, we come back and fix it.
Jobs that need a professional
- Spring balances under tension — they can snap back and cause injury.
- Casement operators on upper floors — the sash can swing free once disconnected.
- Hardware where the wood around the screws has rotted — it needs wood repair first.
- Locks that won't line up because the frame has shifted — the frame needs re-squaring.
Window Hardware by Window Type
Double-hung and single-hung: sash locks that no longer line up, tilt latches that snap in the cold, and the pivot shoes and balances inside the jambs (see balance & sash cord repair).
Casement and awning: crank operators with stripped gears, bent operator arms, worn hinges and multi-point locks that no longer pull the sash tight.
Sliding windows: latches that won't catch and rollers that have worn flat, so the sash drags in the track. For sliding patio doors, see patio door repair.
Whatever the window, the part that failed is replaced on its own — including equivalent parts for discontinued brands.
Window Hardware Repair Cost
Minimum service visit: $150 — several small repairs in the same visit are covered by it.

Repair vs. a new window, per window
The most common reason homeowners get talked into replacing a good window is being told the original hardware is discontinued. It's rarely true that nothing can be done. Many parts have direct aftermarket equivalents, universal replacements can be adapted to fit, and some original hardware can be repaired rather than replaced altogether.
We work with hardware on older and discontinued windows throughout older homes in northern Illinois, matching function and — where it matters — appearance.
Because hardware is a small, self-contained part, replacing it is one of the least expensive window repairs there is, and almost always a tiny fraction of what a whole new window would cost. We give you an estimate after identifying the right part, so you know the price before any work begins.
What wears out in northern Illinois windows
Casement cranks and balances installed in the 1990s–2000s building boom across Lake in the Hills, Algonquin and Huntley are now 20 to 30 years old — beyond the 15 to 25 years most cranks and balances last. Winter cold stiffens grease and makes cranks strip under force, which is why so many fail on the first cold morning of the year.
Warranty on Hardware Installation
Parts we don't make (cranks, balances, locks) carry only their supplier's warranty. Leaks from roofs, flashing or siding aren't window defects. Full warranty terms Read our reviews
Who does the work
- Our own technicians — no subcontractors.
- About 10 years in the trade, on every kind of window and door.
- The same people who give the estimate come back to do the work.
Make the repair last
- Clean and lubricate crank gears and tracks with dry silicone spray once a year.
- Tighten loose screws on latches, keepers and crank handles.
- Never force a stiff crank in cold weather — let the room warm up first.

What Customers Say
"I'm very satisfied with the work done and highly recommend Local Window Service Inc. We had numerous problems with our windows from faulty clips to window fogging and they were able to fix everything at an extremely reasonable price. I thought we were going to need new windows but after the repairs, they look brand new!"
"Great quality, fair and transparent pricing, and the work was quickly done.
We had a crank window in our nursery that wouldn’t shut properly and would slam open and closed when it was windy out (not ideal for a sleeping baby, especially in the winter)
Within an hour after calling, Igor came out to look it over and give us a quote. He ordered the part and came on our schedule once it arrived. He wore a mask inside (which was greatly appreciated) and was able to fix the window in less than 15 minutes.
Would highly recommend Local Window Service and would definitely use again in the future."
"Igor responded within a day and fixed our broken quickly when it was freezing outside! He was very nice and professional. He’ll be my first call if he needs window repairs again!"
