Engineered internal framing enhances durability and ensures long-term structural integrity.

Secure Hardware

Glass Options for Comfort & Clarity
Glass performance plays a major role in how your patio doors feel throughout the year. Advanced insulated units help control temperature transfer, reduce interior condensation, and maintain clear sightlines without sacrificing natural light.
- Low-E glass coatings designed to reduce unwanted heat transfer
- Argon gas–filled insulated units for improved thermal performance
- Warm-edge spacer systems that help reduce condensation at the glass edge

Built-In Mini Blinds
Prefer privacy and light control without extra curtains? Patio doors with built-in mini blinds keep everything sealed between the glass for a clean, modern look and simplified maintenance.
Because the blinds are enclosed inside the insulated glass unit, they stay protected from dust, pets, and everyday wear — helping maintain clarity and smooth operation over time.
- Blinds sealed between glass for a streamlined appearance
- No dusting or wiping like traditional surface-mounted blinds
- Simple light and privacy control with smooth adjustment


Custom Colour Options
Your patio door should complement the rest of your home — not stand out for the wrong reasons. Today’s premium vinyl finishes offer clean, modern colour options designed to coordinate with siding, trim, brick, and stone.
Factory-applied finishes are engineered for durability, helping resist fading, peeling, and surface wear over time. That means your patio door maintains its colour depth and clean appearance season after season.
From classic whites and neutral tones to deeper exterior-inspired shades, there are options to match both traditional and contemporary homes. We’ll walk you through available selections during your estimate so you can choose a finish that fits your style confidently.
Custom colour matching may be available upon request, depending on product line and finish specifications.

Grille Options
Grilles add architectural detail while maintaining energy efficiency. Internal grille systems stay sealed between glass panes, keeping maintenance low and preserving smooth sliding performance.
Choose from multiple layout patterns to match traditional or modern home styles, creating a cohesive exterior look.
- Internal grilles for a clean, protected finish
- Multiple pattern configurations available
- Durable colour-matched finishes

Professional Installation You Can Trust
Even the best patio door depends on proper installation. A clean-looking unit can still underperform if the opening isn’t prepared correctly or the system isn’t sealed and aligned with care. Our team focuses on precision, insulation, and finishing details so your patio door operates smoothly and stays comfortable through real Niagara seasons.
We install patio doors with a “do it once, do it right” approach — measuring accurately, setting the frame square, and sealing the perimeter properly to help reduce drafts, sticking, and water issues.
- Accurate on-site measurements before ordering to ensure the right configuration and fit
- Clean removal of the existing door system with careful protection of interior finishes
- Solid frame setting (level, plumb, and square) for smooth sliding and long-term reliability
- Proper insulation and sealing around the opening to help reduce drafts and heat loss
- Careful finishing for a clean, professional look around trim and transitions
If you’re comparing contractors, the difference usually shows up in the first winter — when the door stays smooth, the seals stay tight, and the opening looks as clean as the day it was installed.
