Moisture damage hides behind your siding

Swollen, cracked boards allow water to seep behind the cladding, where it rots the sheathing. By the time you see soft spots or peeling paint, the damage is often extensive. Addressing it early keeps the job manageable.

Siding replacement here enhances curb appeal and boosts resale value. Modern materials like fibre cement and insulated vinyl provide better thermal resistance than older options. This project offers multiple benefits for your home.

Prevent Moisture Damage

When rain gets behind cracked siding, it rots the sheathing and invites mould. A full siding replacement is the only way to restore a dry, stable exterior. For siding replacement in Vancouver, we use the right materials and installation to keep moisture out for decades.

We remove every damaged board, check the wall beneath, and install a new layer of weather-resistant siding. With tight seams and optional rainscreen, your home stays dry even in heavy rain. This solution adds value and improves curb appeal.

Challenges of Thornhill's Weather

Thornhill gets a lot of rain from October through April. In Thornhill, that constant moisture is tough on siding, especially older wood or composite boards that weren’t installed with modern sealing methods.

Many homes here were built in the 1980s and 1990s, when builder-grade siding was common. Now, those materials need replacement. A properly installed new exterior protects your home from the weather.

Moisture-Resistant Siding

In Thornhill, we use siding products like fiber-cement, engineered polymer, and thick-gauge vinyl. These materials resist moisture absorption and swelling. We avoid traditional wood because it can rot in this damp climate. Our dimensionally stable boards have factory-finished coatings that resist warping from constant rain.

We start installation with a weather-resistant barrier over the sheathing. Then, we create a rainscreen gap using vertical strapping or a drainage mat. Siding boards are attached with corrosion-resistant nails and are lapped to direct water downward and away from the wall. J-channel and trims around windows and doors help to flash water out instead of letting it in.

Structural Performance for Homes

A siding system on a Thornhill home needs to act as a drained and ventilated rainscreen. The outer cladding deflects most rain, while a secondary drainage plane behind it captures any water that gets through. This cavity is vented at the top and bottom, allowing air to move, which speeds up drying and equalizes pressure. This reduces the suction that can pull water in during wind-driven storms.

Flashing details are important at horizontal trim boards, windows, and deck ledgers. Head flashings with drip edges direct water over the siding below. Base flashings at the bottom of walls guide moisture out through weep holes. Proper lapping of weather-resistant barrier layers ensures water drains down and out, never behind the barrier.

We also consider local wind exposure when attaching siding. Fasteners must go deep into the structural framing, not just the sheathing. Nails are placed at the top of each board’s nailing flange, so the head is covered by the next board. This protects it from moisture and improves the wall assembly’s resistance to high winds in the Fraser Valley.

Thornhill Permit Requirements

For siding replacement in Thornhill, construction noise is only allowed Monday to Saturday between 7:00 a.m. and 9:00 p.m. according to the City of Maple Ridge’s Noise Control Bylaw No. 5122-1994. No work is allowed on Sundays or statutory holidays. If your siding project needs to happen outside these hours, you must apply for a temporary construction noise exemption permit from the City of Maple Ridge. You cannot start any after-hours work until you get this approval, which is not guaranteed.

Homeowners must check their property’s zoning, setbacks, and height limits using the City’s Ridgeview mapping application before starting any siding replacement. This step makes sure your project follows the City’s zoning bylaw and related rules.

If siding replacement work in Thornhill must occur outside the standard permitted construction hours, the contractor or owner must apply to the City of Maple Ridge for a temporary construction noise exemption permit. No work outside the allowable days and times may proceed until the exemption is approved, and approval is not guaranteed.

Our Community Commitment

Imagine a local school in Thornhill where years of rain had damaged the exterior siding on several buildings. The siding was warped and allowed moisture to enter the walls. We replaced the siding one building at a time, working around their academic calendar. Each day, we secured the site so classes could continue without interruption. After we installed the new, tightly sealed siding, the school no longer had moisture problems, and the whole campus looked new for the community that depends on it.
