We've seen every issue a loose or misaligned window can develop. Here are the problems our clients call us about most often.
A window that falls closed on its own or needs a prop to stay open usually means the balance spring or cord system has worn out. Continuing to force it can strain the track further. We replace the balance mechanism and confirm smooth operation across the full range.
A rattling sash points to play in the balance mechanism or worn track components that no longer hold the window steady. Left alone, the rattling accelerates wear on the remaining hardware. We diagnose and repair the specific cause rather than guessing at a fix.
A crank that spins freely without opening or closing the window usually means the gear teeth inside the operator arm have worn down. This is a common casement window issue that gets worse with continued use. We replace the operator arm to restore proper function.
A latch that no longer catches securely can let a window rattle or be pushed open with minimal effort. This is usually a worn catch mechanism or misaligned strike plate. We repair or replace the latch so it holds securely every time.
A drafty window that still appears fully closed often means the lock isn't pulling the sash tight against the frame. This affects both comfort and energy costs. We test the lock's actual holding strength and repair or replace it as needed.
A gap between the sash and frame usually points to worn hinges on casement windows or a balance mechanism issue on sliding styles. This lets in air and moisture over time. We assess the specific window type and correct the alignment at the source.
A lock that resists closing or doesn't fully engage is often caused by corrosion, paint buildup, or simple age. This leaves the window less secure than it appears. We clean, lubricate, or replace the lock mechanism depending on the cause.
A rattle that returns after a homeowner tightening attempt usually means the underlying component has actually worn out rather than simply loosened. Repeating the same fix rarely produces a different result. We identify and replace the failed part properly.
Older windows sometimes use hardware that is no longer manufactured, complicating a routine repair. We source compatible replacement parts or adapt modern components to fit, so the repair still resolves the issue without needing a full window replacement.
I assumed my bedroom window just needed new hardware but the technician found the balance spring had failed instead. Ontario Door & Window Pros fixed it in under an hour and the window has been solid since.
The crank on our kitchen window had been spinning without doing anything for months. Turned out to be worn gear teeth in the operator. Quick fix once they had the right part on the truck.
Our window hardware was older and the exact replacement part had to be ordered. The technician was upfront about the timeline and came back within a few days to finish the job properly.
I thought the window sash itself was the problem but it was actually just a worn latch not catching properly. Ontario Door & Window Pros explained the difference clearly and fixed it same day.
Had three windows with similar rattling issues. Booking them together saved money on the service call and the technician handled all three efficiently. Would definitely use them again.
I was ready to pay for a full hardware replacement but the technician said a simple latch adjustment would solve the problem. Appreciated not being upsold on something I didn't need.
