Siding
At A-1 Siding & Windows Niagara, we’ve been installing vinyl and aluminum siding across the Niagara Region and Hamilton area for over 25 years. Whether you’re replacing old, damaged siding or upgrading the look of your home entirely, we supply and install products from three of Ontario’s most trusted manufacturers — Gentek, Mitten, and Kaycan.
Properly installed siding does more than improve curb appeal. It protects your home’s structure from moisture, wind, and Ontario’s freeze-thaw cycles. When siding is installed without proper technique, water works its way behind the panels, insulation is compromised, and small problems become expensive repairs. Our experienced installers follow manufacturer guidelines on every job — no shortcuts.
We serve St. Catharines, Niagara Falls, Welland, Thorold, Grimsby, Fort Erie, Port Colborne, Niagara-on-the-Lake, Stoney Creek, and the greater Hamilton area. Call us at 905-662-5757 or 905-680-2833 for a free estimate.

Frequently Asked Questions
How long does vinyl siding last in Ontario? Quality vinyl siding installed properly typically lasts 20–40 years in Ontario’s climate. The key is proper installation — panels need to be hung with the right fastening technique to allow for expansion and contraction through our freeze-thaw cycles.
What’s the difference between vinyl and aluminum siding? Vinyl siding is lower maintenance, more affordable, and available in a wider range of colours and profiles. Aluminum siding is more durable against impact, holds paint well, and is a good choice for older homes that originally had aluminum. We install both and can help you choose based on your home and budget.
Do I need a permit for siding replacement in Niagara? In most cases, replacing existing siding on a residential home in the Niagara Region does not require a permit. However, requirements vary by municipality — we can advise you during your estimate.
How long does a siding installation take? Most residential siding jobs take 2–5 days depending on the size of the home, the condition of what’s underneath, and the material chosen. We’ll give you a clear timeline before any work begins.
Do you remove and dispose of old siding? Yes — we remove existing siding, inspect the sheathing underneath, and dispose of all old materials. If we find any moisture damage or rot during removal, we’ll let you know before proceeding.
