Century Aluminum installs window capping for Toronto homeowners dealing with peeling, rotting, or moisture-exposed wood trim. Aluminum capping provides a permanent, maintenance-free solution that eliminates repainting and protects the frame year-round. Serving Toronto, Mississauga, Oakville & the GTA. Free estimates available.
Window capping is custom-fabricated aluminum, cut and formed on-site to wrap the exterior wood trim around each window—head, sill, and jambs—sealing it from weather permanently.
We cap the full exterior trim around standard residential windows with custom-formed aluminum. Each piece is measured and bent on-site to match the exact profile of the existing trim, with mitered corners and sealed joints so no wood is left exposed to moisture. Available in a wide range of colours to match or coordinate with your siding and fascia.
Bay windows, arched windows, and other non-standard profiles require more precise fabrication. We measure and form capping pieces to fit the specific angles and curves of your window frame so the finished installation is clean and flush regardless of the window shape.
Most homeowners cap all windows at once for a consistent, finished appearance across the full exterior. We assess every window, note any underlying wood damage before installation, and complete the full house in a single visit where access allows.
Where existing capping has pulled away, failed at the joins, or was originally installed poorly, we remove the old material, inspect the wood underneath for rot or moisture damage, address any structural issues, and install new custom-fitted capping that seals correctly and lasts.
Family-owned, 15+ years installing aluminum capping on window frames, door frames, and exterior trim across Toronto, Mississauga, Oakville, and the GTA. Every piece is custom-fabricated on-site – no stock profiles cut to approximate fit. Every installation is backed by our 3-year service warranty.
Window capping only works if it is fitted and sealed correctly. We fabricate every piece on-site to eliminate gaps, exposed edges, and early failure points.
Painted wood window trim lasts a few seasons in Toronto before peeling and absorbing moisture. Aluminum capping ends that permanently and protects the wood underneath for decades.
Every capping piece is measured and hand-formed on-site to fit your exact window trim dimensions – not cut from stock and forced to fit. Corners are mitered cleanly, joints are sealed, and no wood is left exposed. Colour-matched to your exterior so the finished installation looks integrated, not added on.

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.Posted on 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!Posted on 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.Posted on Google![]()

We were very happy with Gary and his team at Century Aluminum as they replaced our downspouts and eavestroughs complete with leaf guard protection. Gary kept his appointments and his word. The work was completed as promised and the site was kept tidy and thoroughly cleaned up after the work was completed. His team was courteous and professional. We strongly recommend Century Aluminum.Posted on 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.Posted on Homestars![]()

We had an excellent experience with Gary from Century Aluminum. A smallish job needed to be done redirecting a downspout. Gary explained options, including cost effectiveness, and booked that job relatively quickly between their larger commitments.Posted on Google![]()

Very pleased with the professionalism, workmanship, and responsiveness of Gary and his team. They completed the work exactly as requested and quoted, and I would bring them back for another job in a heartbeat. They corrected the pitch of my eavestroughs using new material and strategically repositioned the downspouts to address a longstanding drainage problem. I now feel much more confident that my property is better protected from future water issues.Posted on Google![]()

I needed a downspout replaced. I contacted Century Aluminum and got a response within 24 hours. Gary and staff were professional and in contact with me through the process. Got the work done within a week! I will be calling them again and recommending them for future jobs.Posted on Google![]()

I recently had Century Aluminum come out to reinstall a fallen fascia panel and seal the window capping on the sides of my home. From start to finish, the experience was excellent. They were prompt in responding to my inquiry and came in at a fair price. What really stood out was their honesty — they used the existing materials rather than pushing unnecessary replacements, which I genuinely appreciated. It's refreshing to deal with a company that puts the customer's best interests first rather than upselling at every opportunity. The team was friendly and professional throughout, and the work was done well. I'd have no hesitation recommending Century Aluminum to anyone in the Toronto area looking for reliable, customer-focused exterior work.Posted on 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.Posted on Homestars![]()
