TotalSeal Windows & Doors
We’ve built our business around a simple idea: when the same company that manufactures your windows also installs them, you get better results. Our 60,000-square-foot facility produces up to 150 windows daily using fully automated German equipment from Pro-Line. Every window leaving our production floor gets installed by our own trained teams — no subcontractors, no miscommunication, no surprises.
We serve detached homes, townhouses, semi-detached properties, and condos throughout Southern Ontario. Whether you’re replacing a single kitchen window or outfitting an entire home, our process stays the same: measure precisely, build to spec, install properly.
Manufacturing
Our automated production line turns raw materials into finished windows with minimal human error. When you place an order, our system breaks it into individual components — frames, sashes, glass units, hardware — and routes each piece to specialized machinery. Fusion-welded corners, multi-chamber frames, and precision cuts happen without shortcuts.
We source materials from proven suppliers. Glass comes from Cardinal Glass. Hardware includes Roto multi-point locking systems and Truth operating mechanisms. Vision Extrusions supplies our extruded profiles, while Aluplast provides uPVC profile systems for specific applications.
Energy Efficiency
Toronto winters test every building component. Our windows answer with 5-7 chamber vinyl frames, triple glazing options, and Low-E 272/366 coatings that reflect heat back into your home. Argon and krypton gas fills improve thermal efficiency by roughly 25-30%. Warm-edge hybrid spacers cut heat loss at glass edges and reduce condensation risk by about 25% compared to standard aluminum spacers.
The Modern Slim Flat Profile gives you ultra-thin frames and maximum glass area without sacrificing structural integrity. Our TotalSeal Lock System uses 2-3 adjustable lock points with reinforced strike plates, creating airtight seals while boosting security. Handles come in customizable finishes to match your interior style.
For those chasing the best thermal numbers, triple-glazed casement windows hit U-factors around 1.0-1.3 W/m²K — well below the 1.6-1.9 W/m²K range of typical double glazing.
Adding the optional interior i89 coating can reduce heat loss by another 10-15%. These specifications help many of our windows meet ENERGY STAR® certification standards for Canadian climate zones.
Windows & Doors Installations
A great window poorly installed performs like a mediocre window. Our crews follow a defined workflow: remove old units, prep rough openings, set new windows level and plumb, seal all gaps, and verify operation before cleanup. Every installation gets checked for airtightness and water resistance.
We work with all property types:
Detached homes usually offer straightforward access.
Sometimes need coordination with neighbours or specil staging
Present their own challenges, which we're handled hundreds of times
