    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.

    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

    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.
