    What Can Our Aluminum Siding Service Help You With?

    Whether you are building new, replacing worn siding, or upgrading an older exterior, we install aluminum siding correctly from substrate through to final trim.

    New Siding Installation

    We install aluminum siding on new builds, full replacements, and partial upgrades on existing homes. We check the wall sheathing and moisture barrier before any panel goes on, so the new system starts right and stays right.

    Aluminum Siding Replacement

    Widespread oxidation, multiple dented panels, or siding pulling away from trim are signs the system is past repair. We remove the existing siding, inspect the underlying wall, and install new aluminum to restore both appearance and protection.

    Horizontal and Vertical Profiles

    We install horizontal lap and vertical board configurations. Horizontal is standard on most GTA homes. Vertical works well on accent sections, garages, and contemporary styles.

    Window Capping and Exterior Trim

    Siding without properly finished trim leaves water entry points at every window, door, and corner. We install aluminum window capping and trim as part of every job for a clean, watertight finish.

    Why Choose Aluminum Siding for Your Toronto Home?

    Built for Canadian Weather

    Aluminum does not absorb moisture, rot, or crack from freeze-thaw cycling. It naturally forms a hard oxide layer that protects the metal from further corrosion - making it one of the most weather-resistant cladding choices available for GTA homes.

    Impact Resistant

    Higher-gauge aluminum offers improved resistance to hail and debris compared to lighter materials, though it can still dent under heavy impact.

    Paintable

    Aluminum can be repainted when the original finish chalks or you want a new colour. A fresh coat extends the system's life without a full replacement.

    100 Percent Recyclable

    When aluminum siding reaches the end of its life, every panel gets recycled. Nothing goes to the landfill.

    Coordinated with Soffit, Fascia, and Trim

    We install soffit, fascia, and trim alongside siding, so your full roofline and exterior finish can be matched in aluminum from one contractor.

    Signs Your Aluminum Siding Needs Replacing

    • Widespread chalking or oxidation: The factory finish has broken down and cleaning no longer helps
    • Multiple dented or misshapen panels: Cumulative impact damage compromising the seal at panel joints
    • Panels pulling away from trim or corner posts: Fastener failure or rot behind the cladding
    • Moisture staining on interior walls: Water is getting through the cladding into the wall cavity
    • Siding more than 30 to 40 years old: Older systems pre-date current moisture barrier standards

    Frequently Asked Questions About Aluminum Siding in Toronto

    How long does aluminum siding last in Toronto?

    Properly installed aluminum siding typically lasts 30 to 40 years in the GTA. Its resistance to moisture, insects, and freeze-thaw cycling gives it a longer life than vinyl in most conditions. The finish can be repainted to extend the system further without full replacement.

    Both are strong choices. Aluminum offers greater dent resistance, a longer service life, paintability, full recyclability and is non-combustible. Vinyl costs less upfront and never needs painting. We install both and can help you decide based on your home, budget, and priorities.
    Yes. With proper surface preparation, metal primer, and exterior acrylic, aluminum holds paint well. Repainting is a cost-effective way to refresh faded cladding without replacing the panels.
    A correctly installed system with a continuous moisture barrier reduces air infiltration, which is a primary source of heat loss in Toronto winters. Insulated backer board beneath the panels improves thermal performance further.

    Sometimes. If the existing surface is flat, sound, and free of moisture damage, we can install over it. We always inspect before recommending this approach – installing over a compromised substrate causes the same problems to repeat under the new panels.
