Patio Door Styles We Sell
ALDA Windows and Doors is a factory-direct dealer and installer of patio doors across the GTA – we do not manufacture doors ourselves, so pricing reflects factory cost, not a manufacturer markup, while warranty coverage stays the same as buying direct.
- Sliding patio doors – the most common choice, space-saving since the panel glides instead of swinging, available in 2-panel and 3-panel configurations.
- French patio doors – hinged, swing-open panels for a traditional look and a wider fully-open passage, popular for formal dining rooms and garden entries.
- Folding (multi-slide) patio doors – stack open to create a full-width opening between indoor and outdoor living space, ideal for entertaining.
Energy Efficiency and Security
Every patio door we install is ENERGY STAR rated, with multi-point locking hardware and reinforced glass options for added home security. Popular upgrades include laminated security glass and anti-lift tracks. For a deeper look at hardening an existing patio door, see our guide on Patio Door Security Upgrades for GTA Homeowners.
What to Expect During Patio Door Installation
A standard patio door installation typically takes about 5 to 6 hours on installation day, with lead time on the door itself usually 1 to 2 weeks for standard sizes, longer for custom widths or finishes. For general tips on getting your home ready before the crew arrives, see How to Prepare for Your New Window Installation – the same prep applies to a patio door installation.
Patio Door FAQs
What’s the difference between sliding and French patio doors?
Sliding doors glide horizontally and take up no swing space, making them ideal for tighter patios or furniture placement. French doors swing open like a traditional door and give you a wider, unobstructed opening when both panels are open.
Are patio doors as secure as a front door?
A properly installed patio door with multi-point locking hardware and reinforced glass is very secure. We also offer add-on security upgrades – see our patio door security guide linked above for specific options.
Do patio doors qualify for Ontario rebates?
ENERGY STAR-rated patio doors, which is every model we sell, can qualify for current Ontario rebate programs. Ask your estimator to confirm eligibility for your selected door.
What warranty comes with a patio door?
Warranty ranges from 25 years to a lifetime warranty depending on the manufacturer and product line selected.
