We've seen every issue a door knob or handle can develop. Here are the problems our clients call us about most often.
A wobbling knob usually means the mounting screws have backed out or the internal spindle has worn down. Left alone, the looseness worsens and can eventually cause the knob to fall off entirely. We diagnose whether the fix is tightening or component replacement.
A grinding or scraping sound typically points to worn internal components rubbing against each other inside the mechanism. Ignoring it accelerates wear and often leads to complete failure. We identify the worn part and repair or replace it as needed.
A door that fails to latch even when the knob turns normally usually has a misaligned or worn latch mechanism. This leaves the door insecure even when it appears closed. We repair or adjust the latch assembly to restore reliable closure.
A lever that stays down instead of returning to level usually has a worn or broken internal return spring. This makes the handle look and feel broken even if the latch still works. We replace the spring or the full lever assembly as needed.
Resistance when turning a key usually indicates cylinder wear or internal misalignment inside the lock. This can worsen until the key stops turning entirely. We service or replace the lock cylinder to restore smooth operation.
An intermittently failing lock usually points to a bolt mechanism or cylinder issue that isn't consistent enough to notice right away. This is a security risk since the lock may fail exactly when needed. We test the full lock cycle repeatedly to catch and fix the issue.
A knob that has come off the door usually means the spindle or mounting screws have failed entirely after prolonged wear. This leaves the door unsecured until it's fixed. We reassemble or replace the hardware and restore full function.
A handle that catches or resists during turning often has debris, corrosion, or misalignment inside the mechanism. Continued forcing can damage the hardware further. We clean, lubricate, or replace components to restore smooth movement.
Older or inconsistent hardware across a home can look mismatched and may lack modern security features. This is often a cosmetic and functional concern at once. We help select and install replacement hardware that fits the existing bore pattern cleanly.
I had tightened our front door knob probably five times over the past year and it always came loose again within weeks. Ontario Door & Window Pros found the actual problem was a worn spindle and replaced it. Rock solid ever since.
Our deadbolt was working most of the time but occasionally wouldn't fully engage. The technician diagnosed it as a cylinder issue and fixed it same visit. Glad we called before it failed on us at the wrong moment.
The knob itself was fixed quickly but they had to order a specific spindle for our older hardware, which added a day. Once the part arrived the fix was quick and everything works perfectly now.
Our lever handle had been drooping for months and I assumed that was just how it was going to be. Ontario Door & Window Pros replaced a worn spring and now it snaps back like new. Should have called sooner.
We had a loose bedroom knob, a sticky bathroom lock, and a grinding closet handle. Ontario Door & Window Pros handled all three in under two hours and explained what was wrong with each one.
I assumed we needed a whole new handle set but the technician said tightening and a new spring would solve it. Saved us money and everything works great. Appreciated not being upsold on something we didn't need.
