Hidden damage from old windows

Swollen wood cracks paint and caulking, allowing moisture to seep behind the siding. This dampness leads to rot in the sheathing and framing, weakening the wall. It only worsens through another winter.

Choosing new windows offers more than a dry sill. Modern double-pane units reduce street noise from high-rises and retain heat when the coastal chill sets in.

Preventing Water Damage

Old window frames lose their seal, allowing rain to seep in and swell the wood sills. This constant wetting leads to rot, and you can see the damage grow with every storm. Proper window installation in Vancouver stops this problem by fitting new units tightly so moisture can’t get in.

A flush-mounted replacement window, sealed with high-quality caulk, sheds rain before it can reach the sill. The exterior trim stays dry and strong, even during back-to-back storms. It’s that easy.

Challenges of West End Climate

West End’s streets are filled with older low-rise buildings that face the Pacific directly. When wind-driven rain hits those west-facing walls, leaky windows become a serious issue. In West End, damp sills are common, and they won’t improve on their own.

The mix of concrete towers and wood-frame buildings creates unique challenges. Salt air from English Bay quickly corrodes metal frames, and constant humidity keeps wood damp. A tight, fully sealed window is the only long-term solution.

Flush-Fin Frame Installation

In West End, we usually install windows with vinyl or fiberglass frames. These materials resist damage from the salty air of English Bay. Unlike aluminum, they won’t pit or oxidize over time. The frames have multi-chambered designs that reduce heat transfer.

We secure new windows into the rough opening using a flush-fin mounting style instead of the old nail-on flange. The exterior trim piece completely covers the gap, and we seal it with a continuous bead of high-quality polyurethane sealant. This setup helps water flow away without depending on the old wooden sill for protection.

For glazing, we typically use double-pane insulated units with a warm-edge spacer. This design helps resist condensation in the humid climate. Low-E coatings on the outer pane reflect heat without darkening the glass, which is important for homes in tree-shaded, north-facing areas.

Ensuring Effective Drainage

Every window in a West End building must work with the drainage system. The back of the mounting fin has a sloped sill pan that directs any water outward onto the weather-resistant barrier below. We do not rely on just a single bead of caulk to stop water.

Head flashing above the window frame is placed under the existing building paper. This setup prevents water from getting behind the top flange. This layered approach is especially important on west-facing walls where rain can be driven by the wind. The window unit itself acts as an extra barrier behind this primary drainage layer.

We place fasteners mainly near the corners and mullion points to resist movement from the steady onshore breeze. We use screws with a wide washer head through pre-punched slots, which compress the outer seal without bending the frame. This keeps the air barrier intact from the sheathing to the exterior trim.
