“Max was knowledgeable and honest about his work. We had a window crank that was loose and not properly working. Price was more than reasonable (I paid half of what the condo maintenance guys had quoted!!) And the patience of these guysssss!! Parking was horrendous in downtown toronto and he had to drive around for at least half an hour before parking. Thank you!!!”

“I am beyond grateful to the team at 24/7 Door and Window repair. My partner and I called them on Friday evening, frustrated as our casement window got stuck and the crank handle would NOT budge, leaving us unable to close our windows. I called 24/7 Door and Window repair upset and confused, and they were so supportive and kind. We had a window technician come to our place super quick (and we live in Durham region)! Our technician Alex was AMAZING. He was super efficient, knowledgeable, and generous. He came to our place, assessed the situation, and gave us a fair quote. We went ahead and booked his service — he fixed both our stuck casement windows within 20 minutes and even lubricated two other windows for free! Alex, we appreciate you so much!!!!”

“I’m the owner of a general contracting company. My clients needed a crank replacement for their large kitchen window. I must say I am quite impressed with the front office and the quick/efficient correspondence. I spoke with both Carol and Mary who made me feel confident that the scope of the job was understood. Scheduling was straightforward and simple. My technician Tal was polite, knowledgeable and completed the repair a lot faster than I expected. Honestly, 10/10 experience. I would recommend to any fellow general contractor or homeowner. (Photos show before and after)”

“Our window was stuck, could not open it for a year, had two technicians diagnose it but they could not fix it. Tal spent time on it and figured what the problem was and fixed it in 1-2hours. Repair wait time 1–2 hr”

“Buildnfix did a great job and were very professional fixing our window. Same day service for a broken latch on our window. Will definitely use their service again.”

“We hired this company to fix water leaking from the window frames in our new house whenever it rained. Manny gave us a very reasonable quote, and we were extremely satisfied with the quality of the work. The technician was very professional and clearly knew what he was doing, which gave us a lot of confidence throughout the process. The new caulking was done so neatly and professionally that it can’t even be compared to the previous work. Everything was finished cleanly and carefully, and we were so happy with the results that we even recommended the company to our neighbors.”

“I had a fantastic experience replacing a few cracked and foggy window Glasses. The service was incredibly speedy—from the initial measurements to manufacturing and the final installation, everything was successfully completed within just one week. The new glass looks crystal clear and the installation was flawless. Highly recommend their services!”

Our service
A crank that spins freely, a sash that will not stay up, a failed latch or a draft can often be repaired without replacing the whole window.
We check the window's movement, operator, hinges and alignment. A freely turning crank can point to worn gears or a disconnected mechanism; resistance can have several causes. An on-site assessment helps us identify the fault and decide whether a part repair is suitable.
Casement and awning windows fail at the operator gearbox or at the hinge track. We match the operator to your window make and handing, since these are not universal, and replace it with the sash supported so the hinge arms do not twist. Corroded hinge tracks are cleaned and lubricated or swapped out with the sash off.
A sash that drops or will not stay up may have worn balances, broken cords or another support fault. We inspect the system and match replacement parts to the sash type and weight. Older timber windows may need sash-cord and weight repairs instead.
We check sash alignment, the frame and the locking mechanism before recommending adjustments or replacement hardware. Any security upgrade must suit the window and preserve required emergency escape and safe operation.
We inspect sash seals, closing pressure and exterior joints to find where air or water is entering. Repairs may include matching weatherstripping, adjusting the sash or replacing failed perimeter caulking, depending on the source of the leak.
For broken glass, we assess temporary securing and measure for replacement. Moisture between sealed panes can indicate a failed glass unit. If the sash and frame are sound, replacing the glass unit may avoid replacing the whole window.
Hamilton's lower city holds some of the oldest housing stock in the region, with early-1900s brick homes and rowhouses still carrying original wood windows, while the upper city and mountain areas are mostly postwar and later builds. A working industrial core downtown also means ongoing storefront and commercial glass repairs.
We diagnose first and quote before starting. What drives the cost is which part failed and whether it is a stocked profile or a discontinued one we have to source, the glass size and coating if a unit is involved, upper-floor access, and after-hours attendance.

FAQ
Local answers first, then the ones that apply everywhere.
Yes, including Downtown Hamilton, Westdale, Locke Street, Corktown and the rest of the municipality. We also serve addresses near the boundary with Stoney Creek. Tell us your address when booking. Estimate visits are usually free; we confirm any visit fee in advance.
Yes. Call day or night for immediate emergency dispatch. We assess the damaged opening, remove hazardous glass and arrange appropriate temporary securing. Permanent replacement follows once the glass is measured and ready. We explain any access restrictions and the expected timing on site.
A hardware or glass-unit repair can cost less than a complete replacement when the frame is sound and suitable parts are available. We inspect the window and quote the practical options before you decide. Frame damage or several failed components may make replacement a better choice.
Moisture trapped between sealed panes can indicate a failed glass unit. We check whether the moisture is between the panes or on an accessible surface, then assess the glass, sash and frame. A replacement sealed unit may be all that is needed when the surrounding window is sound.
Usually. Operators, balances and latches vary by manufacturer, series and handing, so we identify the window from the sash label, the hardware casting or a close-up photo. Discontinued parts often have a current equivalent that fits the same footprint. When nothing matches, we say so up front rather than forcing a part that will bind.
