Everyday Window and Door Repair Concerns We Handle

We've seen every issue windows and doors can develop, together and on their own. Here are the problems our clients call us about most often.

🔒

Door Won't Latch or Lock Properly

This usually means the strike plate or latch mechanism has shifted out of alignment with the door. Leaving it unresolved is a real security risk, since the door may not be fully secured even when closed. We realign the strike plate or replace the latch hardware so the door locks properly again.

🖼️

Window Will Not Open or Close Fully

Swollen wood, worn hardware, or a shifted frame are the most common causes of a window that binds partway through its motion. Forcing it can damage the track or crack the frame further. We diagnose the exact cause and adjust the hardware or frame to restore smooth operation.

💨

Drafty Windows and Doors Raising Energy Bills

Worn or missing weatherstripping is the most common cause of drafts around both windows and doors. Left unaddressed, this keeps driving up heating and cooling costs every month. We replace weatherstripping and reseal gaps so the opening seals properly again.

🚪

Sagging Door That Drags on the Floor

A door that has started dragging along the floor usually points to worn hinges that can no longer support its weight evenly. Left alone, the hinges wear further and can eventually damage the door frame. We tighten, adjust, or replace the hinges so the door hangs level again.

🌫️

Foggy or Fogged-Up Window Glass

A cloudy appearance between glass panes usually means the insulated glass unit's seal has failed, letting moisture get trapped inside. This reduces both visibility and energy efficiency. We assess whether the seal can be repaired or whether the glass unit needs replacement.

🔊

Squeaky or Noisy Door Hinges

Dry or worn hinge pins are almost always behind a squeaky door. Left ignored, the friction can eventually wear the hinge to the point of failure. We lubricate, clean, or replace the hinge hardware so the door operates quietly again.

🏢

Storefront Window Frame Cracked or Shifted

Commercial storefront glazing can shift or crack under pressure changes, settling, or impact, and the repair requires different tools than residential window work. Left unaddressed, this can lead to further glass damage or security issues for a business. We assess and repair commercial-grade framing and sealant systems.

🏠

Multiple Windows and Doors Sticking at Once

When several openings across a home start sticking around the same time, this often points to foundation movement rather than individual hardware failures on each one. Ignoring the pattern can let a structural issue go unaddressed. We assess the whole property rather than treating each opening in isolation.

🔧

Broken or Missing Window and Door Hardware

Cranks, handles, hinges, and locks wear out or break over years of daily use, and mismatched replacement parts often fit poorly or fail again quickly. We source hardware matched to the specific window or door type so repairs hold long term.

What Our Customers Say

Rachel M.

One visit fixed three problems

I called about a sticking door, and the technician from Ontario Door & Window Pros noticed two windows nearby had the same early wear. He fixed all three in one visit instead of me having to call back later. Really efficient.

Tom H.

Fast response for a security issue

Our back door lock stopped catching properly and I called worried about security. Ontario Door & Window Pros had someone out the same afternoon and fixed the strike plate alignment. Great response time.

Beatriz C.

Good work, took a little longer than quoted

The repair on our sliding door and two windows went well, though it took about 30 minutes longer than the initial estimate because more weatherstripping needed replacing than expected. The technician explained the extra time clearly.

Greg P.

Storefront glass repaired properly

We manage a small retail space and had a storefront window with a failed seal letting in drafts. The technician clearly knew commercial glazing, unlike a previous company we tried. Fixed correctly the first time.

Samantha L.

Draft gone after weatherstripping replacement

Our whole house felt drafty and I assumed we needed new windows entirely. Turned out most of it was worn weatherstripping across several openings. Ontario Door & Window Pros replaced it all in one visit and the difference was immediate.

Nathan W.

Honest about what actually needed fixing

I expected to be told our old windows needed full replacement. The technician assessed everything and said repair would hold for at least a few more years. Appreciated not being upsold on something we didn't need yet.
