Stop moisture damage for good

Window and door capping in this area is more than a cosmetic fix—it halts the moisture cycle that causes hidden decay. Left untreated, rot spreads behind the trim, compromising the framing that holds everything in place.

This project also ends the annual repainting cycle many homeowners dread. It seals out cold air, making a noticeable difference when damp winds pick up. The clean, low-profile finish complements modern siding choices.

Prevent Rot and Damage

Wood trim around windows and doors collects rain and damp air. When moisture gets in, it causes rot that spreads quickly and weakens the opening. Capping those frames with custom-bent aluminum stops this problem completely.

The aluminum is measured and bent on site to fit each window and door perfectly. It wraps the existing wood and creates a sloped surface that directs water away before it can soak in. This results in a maintenance-free exterior that looks clean and lasts for decades. For window and door capping in Vancouver, this method removes the need for repainting and repairs.

Importance for Burnaby Homes

Burnaby gets a lot of rain from October to April, and many homes still have original wood frames that were not made for that much moisture. Without capping, those frames swell, crack, and eventually rot, letting water get behind the siding.

The mix of older bungalows and newer homes in Burnaby means almost every property can gain from this. Even well-kept wood trim can fail in our wet climate over time. Capping gives every home a uniform, protected exterior that can handle the rain without constant care.

Capping Process in Burnaby

For homes in Burnaby, the capping process starts with measuring each window and door frame. We bend 24-gauge aluminum coil on a portable brake to create a sloped cap with a drip edge. This design helps water flow outward, away from the wood and siding.

We hide fasteners behind the cap or place them in the siding channel. This keeps screw heads from being exposed, which could lead to leaks. All corners and miters are sealed with a flexible, exterior-grade sealant that can handle Burnaby’s frequent rain and temperature changes.

The aluminum has a factory-applied PVDF coating. This coating resists fading, chalking, and corrosion from the coastal air. We match the color to the existing trim on site for a seamless look that lasts for many years.

Drainage and Moisture Control

In Burnaby’s wet climate, window and door capping serves as a secondary drainage layer over the wood trim. It works with the home’s weather-resistant barrier to direct any water that gets behind the siding outward.

The cap is installed with a slight slope to promote runoff and has a drip edge to break surface tension. At the top of each opening, metal flashing is tucked under the siding and over the cap to stop water from getting behind the assembly.

We seal fasteners to prevent moisture from entering, and the aluminum is designed to allow slight movement. This helps it adjust to thermal expansion, which prevents buckling and sealant failure during Burnaby’s temperature changes.
