What Siding Repairs Do We Handle?

Most siding damage on Toronto homes is localized to specific sections. A few panels cracked by impact, a section pulling away from the trim, or caulking that has failed around windows. We fix the specific problem without touching the rest of the system.

Cracked and Broken Panel Replacement

Impact from hail, debris, or landscaping equipment cracks panels and breaks the seal between the cladding and the wall underneath. We remove the damaged panels, inspect the house wrap behind them for moisture damage, and install matching replacement sections.

Loose and Buckled Panel Repair

Panels that have pulled away from the wall or buckled visibly are usually the result of improper original installation that did not allow for thermal expansion, or fastener failure over time. We refasten loose sections with the correct hardware and re-nail or re-clip buckled panels to restore a flat, secure surface.

Aluminum Siding Dent Repair and Section Swap

Dented aluminum panels that have deformed beyond reshaping need to be replaced rather than patched. We source matching aluminum siding profile and color, remove the affected section, and integrate the replacement cleanly with the surrounding panels so the repair is not visible from the street, where possible.

Siding Repair Services Across Toronto & the GTA

A cracked or loose panel left through one Toronto winter allows moisture into the wall cavity. The repair cost today is a fraction of what water damage behind the siding costs to fix later.

Signs Your Siding Needs Repair

Cracked, broken, or punched-through panels: Impact damage that has broken the weatherproof surface and exposed the wall underneath
Visible gaps at corners, windows, or trim joints: Failed caulking or trim that has pulled away, leaving water entry points at the most vulnerable transitions
Panels pulling away from the wall or visibly loose: Fastener failure or thermal movement that was not allowed for in the original installation
Buckled or warped sections: Panels that have deformed and no longer lie flat against the wall, often caused by heat exposure or improper installation
Water staining on interior walls behind the siding: Water has already entered the wall cavity through a breach in the cladding or house wrap

 Trustindex verifies that the original source of the review is Google. The team arrived on time, did the repair work quickly and accurately, and gave great advice without trying to upsell services.

What I wasn’t happy about was Gary mocking a customer with a disability. If I wasn’t getting work done for elderly family members, I would have kicked the **** out of Gary.

Gary and his team were very professional and the quality of work is excellent. Everything was seamless from beginning to end. A clear quote was provided detailing scope of work, estimated time for initiation and completion of work. There were some out of scope issues that arose during the installation which Gary fixed without added cost. He even offered to install a new porch light aa ours was broken. Definitely went above and beyond. I’m certain this company will stand behind their product and installation for years to come.

 Trustindex verifies that the original source of the review is Google. Gary was recommended by a friend, and he did a great job putting new siding on our house. Very professional, reasonable price, and easy to work with.

He provided lots of options, answered all of my questions, and paid attention to the finer details, which shows he takes pride in his work. He even took some of the scrap that I had sitting around after some demolition I had done in preparation for Gary and team.

I would absolutely recommend Gary to anyone who needs siding or aluminum work.

 Trustindex verifies that the original source of the review is Google. We used Gary and his team to replace the original, 30-year-old eavestroughs on our home with a better, modern system. His quote was good, he showed up exactly when promised, and did a great job. We will use Century again if we need more work done.
Thanks Gary!

 Trustindex verifies that the original source of the review is Google. Gary was great to work with through the entire process. I reached out for a quote and Gary was quick turning that around and was really helpful in answering all my questions. When it came time to do the work, he walked me through the work he would be doing in detail. The new eavestroughs look amazing, they did such a great job! I'd happily hire Gary and team again.

 Trustindex verifies that the original source of the review is Homestars. Gary did an outstanding job repairing my eavestroughs, and I am completely happy with the results. His communication was fast and clear from the start, keeping me informed every step of the way and even fit me in earlier when he had an opening. He took the time to offer different options to fix the issue and helped me choose the best path forward. The quote was transparent with no hidden surprises, and the work itself was finished quickly and effectively. Most importantly, after a recent heavy rain, I can confirm there is no leaking at all. I strongly recommend Gary to anyone needing eavestrough repairs and would hire him again. Five stars.

 Trustindex verifies that the original source of the review is Homestars. Gary was extremely informative and patient when he dropped by for quote and that was one reason I went with them instead of the others we got a quote from. The job was done with precision and patience and Gary and his team were quite polite and helpful. They pointed out and helped resolve some of the other issues that weren't in the other contract either. Good service, good experience.

Frequently Asked Questions About Siding Repair in Toronto

Can damaged siding be repaired without replacing the whole exterior?

Yes, in some cases. When damage is isolated to specific panels, sections, or joints, targeted repair is the most cost-effective solution. Replacement makes more sense when damage is widespread, when matching replacement panels are no longer available, or when moisture has compromised the house wrap across a large area. We assess the full extent of damage before recommending either option.

Will repaired siding panels match the existing cladding?

For relatively recent installations, matching panels are usually available. For older systems, particularly older aluminum siding, an exact colour match may not be possible as manufacturers discontinue profiles and colours over time. We tell you before starting the repair whether a visual match is achievable, and give you the option to proceed or to consider a broader replacement.

How much does siding repair cost in Toronto?

Cost depends on the number of panels affected, the material, and the accessibility of the damaged area. Most localized repairs are significantly less expensive than a full re-clad. Century Aluminum provides free on-site and online estimates before any work begins.

What causes siding to crack or buckle in Toronto?

Cracking is most often caused by impact damage, UV degradation on older vinyl, or freeze damage on panels that have absorbed moisture. Buckling is almost always the result of improper installation that did not allow adequate clearance for thermal expansion. Aluminum and vinyl both expand and contract with temperature changes, and panels fastened too tightly have nowhere to go but outward.

Can siding repairs be done in winter in Toronto?

Minor repairs and panel replacement can be completed in winter as long as temperatures are above the minimum temperature for the specific product. We assess conditions before booking winter repair work.

Fix the Breach Before Water Gets Into Your Walls.

A cracked or loose panel is a small fix today and a much larger problem tomorrow. Call Century Aluminum or fill out our form and we’ll get back to you within one business day.
