Balcony leaks ruining your exterior

Water from a failing balcony damages more than just siding. It seeps behind cladding and into wall assemblies, causing hidden rot that becomes costly over time.

A fitted membrane protects the structure from heavy rain, keeps the deck cooler in summer, and prevents freeze-thaw cycles that damage homes in this area.

Effective Balcony Drainage

When water sits on a balcony, it doesn’t stay there. It seeps into the deck and runs down, damaging the siding and trim below. A good balcony membrane in Vancouver stops this problem—it directs water away before it can cause harm.

Our installers take off the old surface and lay a seamless membrane that slopes to the drain. No seams mean no tiny holes for water to get through. This creates a balcony that sheds rain quickly and keeps the exterior dry and strong for years.

Moisture Issues in West Bay

Homes in West Bay sit on steep slopes and face sideways rain and ocean mist. A balcony that doesn’t drain well sends water straight into the siding below. Moisture and salt air speed up rot and staining in these areas.

Many properties here have multi-level decks and balconies with wood or stucco siding underneath. This setup needs a watertight membrane that can handle our wet winters and constant dampness. Our team knows the local building details and tackles the specific drainage issues these hillside homes face.

Balcony Membrane Installation

In West Bay’s steep areas, we start by removing the old surface to reveal the plywood base and check for rot. Next, we re-slope the deck using a tapered mortar bed or sloped sheathing to guide water to the drain. For this coastal climate, we use a strong PVC membrane that resists salt air and UV damage.

We heat-weld the seams to create a continuous surface that prevents leaks. The membrane goes up the wall and fits behind the siding’s weather-resistant barrier, ensuring that water hitting the wall drains onto the membrane. At the balcony edge, we add a metal drip edge to direct water away from the siding below.

Balcony Membrane Performance

A balcony membrane in West Bay must work as a main drainage layer, shedding water before it can reach the building. We slope the deck surface to ensure proper drainage, stopping water from pooling, which can damage the membrane. The membrane extends over the edge to create a barrier that prevents water from soaking back into the siding.

We use corrosion-resistant fasteners to hold the system in place against wind uplift and salty air. At the ledger board, we install continuous flashing that connects to the wall’s drainage layer, directing any moisture that gets behind the siding out and down. This layered method keeps the structural framing dry during heavy rain.
