Siding that resists moisture

The buckling and gaps you see are not just cosmetic. They allow moisture to get behind the boards, which can damage your home’s exterior structure over time. James Hardie siding is made to prevent this. Its fiber cement formula resists swelling, warping, and rot, even during wet seasons.

We replace the damaged material with HardiePlank lap siding or HardiePanel vertical siding. We seal every joint with proper flashing. This creates a stable, rain-shedding shell that keeps your home dry. For a closer look at how we do this, check out our approach to James Hardie siding in Vancouver.

Weather issues in Dunbar-Southlands

Dunbar-Southlands faces the same damp, Pacific air that affects the rest of Vancouver. Older wood siding in this area absorbs moisture, leading to peeling paint and soft spots you may already see.

Many homes here were built years ago with siding not designed for this climate. A modern, pre-finished Hardie installation sheds water and withstands the salty breezes from the Strait of Georgia. Learn more about the area we serve in Dunbar-Southlands.

Hardie Siding Installation

In Dunbar-Southlands, we start by taking off the old siding and checking the exterior sheathing for any moisture damage. Next, we put a weather-resistant barrier (WRB) over the sheathing, overlapping the seams like shingles to help shed water. To create a rain screen, we attach vertical furring strips over the WRB, leaving a gap for drainage and ventilation behind the Hardie siding.

For secure attachment, we use stainless steel ring-shank nails driven into the wall studs for each plank. The salt-laden air in the area makes these fasteners resistant to rust and helps them handle wind uplift. We set the nail heads flush and install HardiePlank laps with a 1/8-inch gap at butt joints, which we fill with color-matched, flexible sealant to allow for thermal movement.

Moisture Management

Behind every Hardie board in Dunbar-Southlands, the drainage plane is key to stopping moisture intrusion. We combine a WRB with self-adhered flashing at windows, doors, and transitions. This setup ensures that any water that gets behind the siding is directed down and out through a vented bottom drip cap. This keeps the wall dry even during long periods of rain.

The siding is fastened to handle wind loads common in exposed Vancouver neighborhoods. The use of ring-shank nails and a rainscreen gap helps reduce the risk of mold by allowing moisture to evaporate from both sides of the siding. This method helps prevent rot and extends the life of your home’s exterior.
