Moisture damage to your trim

Without capping, moisture from the coastal air seeps into wood trim, causing it to swell and rot. This damage can weaken the frame and lead to expensive repairs.

Capping also seals gaps around frames, reducing drafts that increase heating costs in winter. It provides a clean edge that endures years of harsh weather without peeling or fading.

Protect Your Trim from Moisture

Window and door frames face harsh coastal weather long before siding shows wear. Water seeps into wood, paint blisters, and joints start to rot from the outside. Paragon covers these vulnerable surfaces with aluminum that sheds moisture on contact. This stops damage without needing to replace the entire frame.

The fix wraps each piece of exterior trim in a custom-bent jacket. It is cut and folded on site to match your home’s exact profiles. Homeowners get a low-maintenance barrier that never needs painting and won’t swell, crack, or peel. For homeowners in Metro Vancouver, window and door capping in Vancouver provides a tight, weatherproof seal for both flat stock and multi-step colonial profiles.

Why It Matters in Semiahmoo

The breeze off Boundary Bay and Semiahmoo Bay brings salt and dampness that settles into exterior woodwork. South-facing trim on homes near the water faces extra exposure, with morning dew, afternoon sun, and evening fog all in one day. Capping keeps that moisture out where it matters most.

Many homes here were built from the 1970s to the 1990s, with cedar trim that has weathered years of coastal cycles. Adding aluminum armor extends the life of those original frames and keeps curb appeal strong in neighborhoods where well-kept exteriors are common. Our crews know the Semiahmoo streets well and arrive with the right coil stock to match local trim styles.

Capping for Semiahmoo Homes

Our teams bend each capping piece on site using portable brakes to fit your Semiahmoo home’s trim profiles. We use aluminum coil that is .024 inches thick or more, with a factory-applied PVDF coating. This coating is designed to resist salt spray and damp air from Boundary Bay, preventing pitting or fading. The metal is cut, folded, and hemmed to quickly shed water, with no exposed fasteners that could cause corrosion.

Many homes in Semiahmoo have multi-step colonial or flat stock casing. The aluminum wraps tightly around every contour, including sill projections and shadowlines, leaving no edges where moisture could gather. We seal lap joints with a flexible polyurethane sealant that stays effective during cool, damp seasons, ensuring the shell remains weathertight.

Durability in Semiahmoo

When we cap trim, we see it as a secondary drainage layer that protects the original wood from getting wet. Behind the aluminum, any moisture can still dry into the wall cavity because we keep the existing flashing and housewrap details intact, preventing humidity from being trapped against the frame. In Semiahmoo’s coastal climate, head flashing and sill drip edges are crucial to direct rain away from the siding and foundation.

We use corrosion-resistant fasteners that anchor into the building’s structural framing, not just thin trim nails, to keep the metal secure in strong winds from the bay. We also prevent contact between aluminum and other metals like copper or treated lumber to avoid galvanic corrosion. We design slotted holes at longer spans to absorb thermal movement, so sunny afternoons followed by fog won’t cause unsightly buckling.

Capping Bylaws in Surrey

In Semiahmoo, the City of Surrey’s Noise Control By-law No. 7044 limits construction noise from window and door capping to 7:00 a.m. to 10:00 p.m., Monday through Saturday. Hired trades like Paragon Exteriors cannot perform for-profit capping work on Sundays unless a special noise extension permit is obtained from the City of Surrey.

If window and door capping work in Semiahmoo needs to happen outside these hours, the contractor must apply for and get a Noise Extension Bylaw Permit from the City of Surrey before starting. This permit allows for schedule flexibility while ensuring compliance with the law.

Surrey’s property use bylaws state that tradespeople may only perform capping work between 7:00 a.m. and 10:00 p.m., Monday through Saturday, including statutory holidays. Homeowners can do their own capping work on Sundays, but they cannot hire Paragon Exteriors or other contractors for Sunday work without following the extension permit rules.

Serving Semiahmoo Schools

A local school in Semiahmoo had problems with moisture getting in through their old window and door trim. We capped every window and door on their campus in phases. We worked around their daily schedule so students and staff were not disturbed. When we finished, the openings were sealed against dampness, and their maintenance staff no longer had to deal with peeling trim and soft spots.
