    What Does Our Door Capping Service Include?

    Door capping is custom-fabricated aluminum sheeting cut, bent, and fitted to wrap the full exterior of your door frame – sealing the wood underneath from weather exposure permanently.

    Entry Door Frame Capping

    We cap the full exterior wood frame around entry doors with custom-fitted aluminum, protecting the head, jambs, and sill from moisture infiltration, UV fading, and the need for seasonal repainting. Every piece is measured and hand-formed on-site for a precise fit with no gaps at the joins.

    Garage Door Frame Capping

    Garage door frames take more weather exposure than any other door on the home. We wrap the full frame perimeter with heavy aluminum capping in a colour matched to your garage door and exterior finish, eliminating wood rot and paint maintenance in one installation.

    Side and Back Door Capping

    Secondary doors are often overlooked until the frame is visibly deteriorated. We cap side entry and back door frames using the same custom-fabricated aluminum as our primary door work, with colour options to coordinate with your full exterior.

    Recapping and Frame Repair

    Where existing capping has failed, pulled away, or was originally installed poorly, we remove the old material, inspect the wood underneath for rot, address any structural damage, and install new custom-fitted capping that seals correctly.

    Door Capping in Toronto, Mississauga & the GTA

    A rotting door frame left untreated spreads to the surrounding wall framing. Aluminum capping stops the damage permanently and ends the cycle of repainting for good.

    Why Choose Century Aluminum for Door Capping?

    We fabricate every capping piece on-site to the exact dimensions of your door frame – no standard stock pieces cut to fit. The result is clean, flush joins with no exposed wood edges where water can penetrate. Colour-matched to your exterior so the capping looks like part of the original finish, not an afterthought.

    Custom-fabricated on-site for a precise fit at every join

    Wide colour range to match garage door, siding, and trim

    Full frame coverage including head, jambs, and sill

    Signs Your Door Frame Needs Capping

    • Peeling or flaking paint on the door frame: The wood surface has absorbed moisture and the protective coating has failed.
    • Soft or spongy wood at the frame edges: Rot has started and the structural integrity of the frame is compromised.
    • Visible gaps between the frame and surrounding cladding: Water is entering behind the frame and saturating the wall framing underneath.
    • Annual repainting that never seems to last: The wood is cycling through moisture absorption and drying too fast for paint to bond and hold

    I've hired Century Aluminum twice, to replace eavestroughs and to install de-icing cables. Gary is great to work with, very thoughtful and professional. I have an unusual roof configuration and he helped me figure out a gutter solution to redirect water from a problem area. The quality of their work is excellent and the pricing is reasonable, too. I would definitely recommend Century Aluminum and I'm sure I'll have them back for future exterior projects.

    Gary and his crew did an excellent job replacing the gutters and downspouts on my house, and everything during the whole process was conducted professionally and honestly. Gary was also very responsive and answered all questions I had before, during, and after the work was completed. Very much appreciated, thank you!

    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.

    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.

    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.

    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 Door Capping in Toronto

    What is door capping and how does it work?

    Door capping is custom-cut and formed aluminum sheeting that wraps the exterior wooden frame of a door, covering it completely. It seals the wood from moisture, UV exposure, and temperature cycling that cause paint to peel and wood to rot. Once installed, the aluminum requires no painting and protects the frame indefinitely.

    Properly installed aluminum door capping lasts decades. Aluminum does not rust, and the factory powder-coat finish resists UV fading and road salt. It will outlast any paint applied directly to wood in a Toronto climate. The wood underneath is protected from further deterioration for the life of the capping.

    If rot is minor and structural integrity is intact, capping can be installed after the affected surface is treated. If rot has penetrated deeply into the frame or spread to the surrounding wall framing, the rotted material needs to be removed and the frame repaired before capping goes on. We inspect and report on the condition of the wood before installing anything.

    Yes. We carry a wide range of aluminum colours and can match or closely coordinate with your garage door, siding, fascia, and trim. Colour selection happens before fabrication so the finished installation integrates with your exterior rather than standing out from it.
