Window capping Edmonton replacement & repair

Over 70 years of experience installing window capping.

Your windows are generally the most vulnerable part of your home. The wood of your window casement regularly takes a pounding from wind, rain, and snow, and can sometimes rot because of seeping moisture. Constantly stripping down and repainting your windows can be extremely tedious work. In places like Edmonton and St. Albert, window capping is an essential part of weather-proofing your home.

How does window capping work?

Window capping involves the installation of a more durable material over top of the original window trim. The most common material used for window capping is painted aluminum, though vinyl-coated aluminum can be a good option as well. At A. Clark Roofing & Siding, our Edmonton contractors expertly cut and form the aluminum or vinyl sheeting to fit snugly over your window casing. The capping is then caulked to ensure a proper seal.

Window capping applications and benefits

The main purpose of capping a window is to make the window more weather resistant. The capping protects the original casing from the damaging effects of wind, rain, snow, and hail. Of particular importance is the fact that window capping can effectively keep out moisture, which is crucial for preventing wood rot and water leaks in your home. By sealing off any potential leaks and drafts, window capping can also help make your home more energy efficient.

Another common reason why homeowners choose window capping is to enhance their curb appeal. Old and worn window trim with peeling paint looks drab and will detract from your home’s exterior. Window capping can instantly update the look of your home while also reducing your future window maintenance, as it can go a lot longer than wooden casing before needing to be repainted.

Is capping a window a DIY project?

The benefits offered by window capping, though very appealing, are only guaranteed if the capping is installed correctly. Window capping needs to be installed in such a way that it prevents water from leaking through to the original wood window casing underneath. Any leak in the new capping could actually worsen wood rot. Quality workmanship will prevent leaks and create an outlet for moisture. At A. Clark Roofing & Siding, we also take care to first replace any damaged trim that would cause issues in the future. Capping a window is definitely a project best left to experienced Edmonton siding companies.
