I highly recommend Keller! The windows which I had replaced in my home are wonderful and I was very pleased with working with Keller. John Keller was very professional and honest in his recommendations for my windows as well as giving me a fair price for quality windows and workmanship. This is the only company to go with for window and door installation!

Expert Window Hardware Repair in O'Fallon, MO
Window hardware repair in O'Fallon covers the moving parts that keep your windows working safely every day. Keller Window & Door LLC fixes broken locks, worn sash balances, stripped crank operators, damaged hinges, and bent or corroded tracks. When hardware fails, windows stick, rattle, or refuse to latch. That creates security gaps and lets conditioned air escape. O'Fallon sits in a region with hot, humid summers and cold winters. That seasonal swing puts real stress on metal and plastic hardware year after year. Homes across the area show common wear patterns: locks that no longer catch, sashes that drop on their own, and cranks that spin without moving the sash. We inspect the full hardware assembly before recommending any part. If a component can be adjusted, we adjust it. If it needs replacing, we source the correct part for your window type. Call Keller Window & Door LLC to schedule a hardware inspection for your O'Fallon home.

FAQ
Window Hardware Repair FAQ
Common questions about window hardware repair in O'Fallon, MO.
Yes, most hardware issues in O'Fallon homes can be fixed by replacing or adjusting the specific component that has failed. A full window replacement is rarely needed when only the lock, balance, or operator is worn.
We repair locks, sash balances, crank operators, hinges, tracks, and tilt latches on most residential window types in O'Fallon. If a part is no longer available, we can advise on the best path forward.
A window that drops closed on its own almost always has a worn or broken sash balance. Keller Window & Door can inspect and replace the balance so your O'Fallon window holds its position safely.
Yes, a misaligned lock is a common hardware issue we see in O'Fallon homes and is usually corrected by adjusting the keeper or replacing the lock assembly. We check the full latch mechanism to make sure it closes and locks securely.
We inspect both the hardware and the frame during every service visit in O'Fallon to identify the actual source of the problem. If the frame has shifted or warped, we will let you know before any hardware work begins.
Yes, we work on hardware for casement, double-hung, sliding, and awning windows throughout O'Fallon. Each window style uses different components, and we carry parts suited to the most common types found in local homes.
