Expert Door Hardware Repair in O'Fallon, MO

Door hardware repair covers the components that keep your doors working every day. That includes hinges, latches, locksets, strike plates, door closers, and handles on entry, interior, and patio doors. When hardware fails, doors stick, swing loose, or stop latching. That creates security gaps and daily frustration. In O'Fallon, the region's wide temperature swings between humid summers and freezing winters put real stress on metal hardware. Repeated expansion and contraction can loosen screws, wear hinge pins, and cause strike plates to shift out of alignment. Older homes and newer builds alike run into these issues. Keller Window & Door LLC inspects the full door system, not just the broken part. We identify what caused the failure, correct the fit, and replace hardware that has worn past the point of adjustment. If your door is dragging, rattling, or not latching cleanly, contact us to schedule a repair visit in O'Fallon.

Door Hardware Repair FAQ

Common questions about door hardware repair in O'Fallon, MO.

Yes, we repair hardware on interior, exterior, and patio doors throughout O'Fallon. This includes hinges, locksets, latches, strike plates, handles, and door closers.

A misaligned strike plate is the most common cause of that problem in O'Fallon homes. The latch bolt and strike plate opening are no longer lined up, which we correct by adjusting or repositioning the plate.

Hardware that is loose, worn, or misaligned can often be repaired without full replacement. We inspect the condition of each component and recommend replacement only when the part is too damaged to hold a proper adjustment.

Yes, O'Fallon's freeze-thaw cycles cause metal hardware to expand and contract, which loosens screws and shifts alignment over time. Catching these issues early prevents bigger problems with the door frame or locking mechanism.

Yes, Keller Window & Door LLC services door hardware on both residential and commercial properties in O'Fallon. We work on entry doors, interior passage doors, and doors with commercial-grade closers or locksets.

A self-swinging door is usually caused by hinges that are out of plumb or a door that is no longer hung level. We adjust the hinge position or replace worn hinge hardware to correct the swing.

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!

It was a pleasure working with John and his crew. They were helpful and did an excellent job with installation. I would use them again and recommend to anyone in need of a new patio door or other items they sell. Brenda Wilson

I love my new windows! What makes them even better is that the whole experience with Keller was very positive! I wish all contractors worked like John does. He was quick to reply for an estimate. His price was very fair. He came to install the windows when he said he would and he did what he said he would. (He actually did a little extra.😊)John and his crew were respectful, efficient, friendly. They protected my floors. They cleaned up after themselves. And they didn’t try to charge me extra for unforeseen issues. They wanted me to be happy and I AM. VERY. My new Andersen Windows are gorgeous and I would definitely recommend Keller Window and Door to my friends!!

John Keller and his team did an AMAZING job installing our new Anderson windows on our Sun porch! They were professional, friendly & courteous. John is extremely knowledgeable and knew exactly the right windows needed to match our historic neighborhood’s guidelines. John was wonderful to work with. I highly recommend Keller Window and Door!
