Window Capping
Professional window capping (aluminum cladding) in Toronto & GTA. Maintenance-free finish that protects trim and eliminates painting forever.
About Our Window Capping Service
Window capping wraps the exterior wood trim around your windows with durable aluminum cladding. Like door capping, it creates a maintenance-free, weather-resistant finish that eliminates painting and prevents rot.
We custom-bend aluminum on-site to precisely fit each window's trim profile. Corners are mitered and sealed for a clean, professional appearance. The result lasts decades without fading or peeling.
Window capping is especially valuable for hard-to-reach windows where painting is difficult or dangerous. Many homeowners do all windows at once for consistent appearance.
Match Your Siding
If you're planning siding replacement in the next few years, consider matching your window capping colour to the new siding. Or cap now in a neutral colour (white, brown) that works with most siding options.

Frequently Asked Questions
Common questions about window capping services.
QHow much does window capping cost?
Pricing depends on window size and quantity. Contact us for a free quote — we'll measure all your windows and provide detailed pricing.
QCan you cap vinyl or aluminum-clad windows?
We typically cap wood trim, not the window frames themselves. If your windows are already vinyl or aluminum-clad, they may not need capping.
QDoes capping improve energy efficiency?
Indirectly. By sealing gaps in trim, capping can reduce air infiltration. But the primary benefits are maintenance reduction and weather protection.
QCan I cap windows myself?
It's possible, but achieving professional results requires experience with aluminum bending and fitting. DIY attempts often look amateur.
