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.

Balcony Membrane Permit Requirements

Balcony membrane work on a home is likely treated as construction noise. Noisy work must follow the District of West Vancouver Noise Control Bylaw No. 4404, 2005’s limits and permitted hours. Exterior work on a balcony membrane may need a building permit review. It must also comply with the District of West Vancouver Building Bylaw No. 5340, 2025 and the Building Code requirements for the work being done. Any changes to the exterior of a building, including balcony-related finishes, need Planning Approval in West Vancouver. This can affect balcony membrane replacement if the work changes the exterior look or related finishes.

Balcony Membrane Projects

We worked on a multi-building school in West Bay that had old balcony membranes. These membranes were causing water to pool and seep into the exterior walls, which could lead to serious moisture damage. To fix this, we replaced the membranes in phases while classes were still in session. We worked closely with their facilities staff to plan around arrival and recess times, ensuring that work zones were safe and sealed off. The result is a drier, safer environment where staff do not have to worry about hidden moisture damage.
