Sliding patio doors: FAQ
How much does patio door replacement cost in Kitchener?
Sliding patio door replacement in Kitchener typically costs $1,800 to $3,500 installed, depending on size, material, and glass package. Larger multi-panel doors cost more. We give you a firm written quote after measuring.
Sliding patio door or French door — which is better?
Sliding patio doors save space because they glide instead of swinging, making them ideal for tight decks and patios. French doors swing open for a wider, more traditional look. If you want the classic swing, see our entry & French doors page.
Are patio doors energy-efficient?
Yes. Modern sliding patio doors use insulated frames, multiple weatherstripping seals, and Energy Star® glass to stop drafts. Replacing an old, leaky patio door is one of the fastest ways to cut a draft in a KW home.
How long does patio door installation take?
Most sliding patio doors are replaced in a single day. We remove the old door, install and seal the new one, and clean up before we leave.
