Paragon

Beyond surface damage

Those soft spots can lead to bigger issues. Moisture inside the wood spreads, causing more damage to your home’s exterior. What starts small can quickly escalate into structural problems.

Flaking paint and cracked caulking signal potential rot. We repair these areas precisely to prevent water from seeping into the wood. A solid, sealed exterior is essential for lasting protection.

Eliminate Wood Rot

Soft, spongy trim means moisture has damaged your home’s exterior. If you ignore it, rot spreads to siding, window frames, and structural supports. Our Wood Rot Repair service finds the source, removes the decay, and replaces it with materials that resist rot.

We use pressure-treated lumber, fiber-cement trim, and marine-grade sealants that handle Metro Vancouver’s rainy climate. Your exterior stays watertight, looks clean, and lasts for years.

Service Area: Queens Park

We repair wood rot in Queens Park, where cracked siding and peeling paint let pests and moisture in. Our wood rot repair service fixes your home’s exterior and keeps wildlife out.

Our rot-resistant materials and careful sealing keep your Queens Park home dry and secure through rainy seasons.

Repair Materials and Techniques

We often use fiber-cement trim, cellular PVC boards, and pressure-treated lumber for repairs. These materials resist decay well. Pressure-treated wood has copper-based preservatives that stop fungal growth. Fiber-cement and PVC are rot-proof. For areas with high moisture, we sometimes use marine-grade plywood for soffit repairs.

First, we cut out the decayed wood until we reach solid wood. Then, we treat the area with a borate preservative to stop hidden spores. We attach new materials with stainless steel screws to avoid rust. All cut ends and field cuts are sealed with primer or end-grain preservative before installation. We also use polyurethane sealant at joints to prevent moisture from entering.

Structural Integration and Drainage

Every repair must connect to the existing weather barrier. We install flashing in a shingle-lap style so water drains outward at horizontal transitions. Head flashings help divert water away from window and door trim. This setup keeps the drainage plane behind the cladding and stops water from wicking into the wall assembly.

We drive fasteners into the structural framing, not just the sheathing, to handle wind loads and resist pull-out. Where trim meets siding, we leave a small gap for any moisture to dry. Our goal is to create a continuous water-shedding surface that allows the building envelope to dry to the outside.

Bylaw Requirements for Repairs

In the City of North Vancouver, fixing significant wood rot on the outside of a building with more than two units usually needs a building permit under the Construction Regulation Bylaw No. 7390. Minor, isolated repairs may be exempt at the inspections manager’s discretion. If your multi-unit home needs large-scale siding or trim replacement, make sure to plan for a permit.

If your home is in the Ottawa Gardens Heritage Conservation Area in North Vancouver, wood rot repairs that change or replace siding, windows, or architectural features usually require a Heritage Alteration Permit. Routine maintenance that doesn’t change these elements is exempt. Check with the city before starting any repair that goes beyond simple patching.

In Burnaby, noise from repair work is limited to weekdays from 7 a.m. to 8 p.m., Saturdays from 9 a.m. to 8 p.m., and is not allowed on Sundays or holidays. Continuous noise must stay below 85 dBA at a distance of 15.2 metres from the source. This bylaw affects when your contractor can use power tools for wood rot repair, so scheduling may need to fit these hours.

Repair Projects Overview

A local school campus needed help because moisture had caused rot in window frames, fascia, and trim. This raised worries about water getting inside and damaging the structure. The crew planned the work around the school year, making sure the site was safe for students and staff each day. They took out all the damaged wood and replaced it with rot-resistant materials. They also added proper flashing to stop future issues. The result was a dry, stable exterior that reduced the risk of more damage and let maintenance staff do their main jobs.
