Leaks lead to expensive repairs

Once moisture gets behind weakened seals, it can rot the wood trim around your openings, causing structural issues that demand costly fixes. In this rainy coastal zone, that damage often spreads quietly for months.

Flashing around windows and doors in this area prevents rot and seals out drafts that spike heating bills every winter. Tight seals keep heat inside where it belongs, providing immediate comfort even before the paint dries.

Prevent Water Damage

When flashing around windows and doors fails, water seeps behind the siding and rots the structure. A small leak can quickly lead to expensive exterior repairs. Paragon Exteriors stops this cycle with strong, durable flashing that seals every gap.

We begin by removing old, cracked sealant and installing new flashing that fits with your siding. This creates a barrier that directs water away, keeping your home dry and safe. For homes in the area, window and door flashing for Vancouver homes makes a big difference in avoiding damp problems and ensuring peace of mind.

Importance for North Vancouver

North Vancouver experiences heavy rain and wind that push moisture into every gap. Without good flashing, water can get behind the siding and around window frames, causing rot and mold on exterior walls.

Many homes here were built years ago with outdated or no flashing. In North Vancouver, upgrading to modern, well-installed flashing protects against the constant wet weather and keeps your home’s exterior in good shape for years.

Flashing Installation in North Vancouver

In North Vancouver, we start window flashing installation by removing old caulking and checking the rough opening for moisture damage. Next, we apply a one-piece sill pan with a sloped bottom, back dam, and end dams that direct water outward. Since rain often comes in heavy bursts, we use a continuous layer of flexible butyl flashing tape. This tape sticks well in damp conditions and seals the rough sill and bottom corners before the window is installed.

For side flashing, we ensure it is shingle-lapped under the house wrap. This setup allows moisture to flow down and out, preventing it from getting behind the weather barrier. A metal drip cap at the top fits under the cladding above and extends over the window frame with a slight outward angle. This detail works with the rainscreen cavity to drain any water that might get past the siding, which is important for North Vancouver’s frequent rain.

Where the window flange meets the siding, we use a high-performance exterior sealant joint. This joint allows for building movement while resisting wind-driven water. Proper tooling creates a uniform bead that bonds to both surfaces, providing a final defense against the wet and windy conditions in the region.

Drainage in Building Envelope

Flashing at windows and doors serves as the first line of defense in a layered drainage system. The main idea is clear: water should never be trapped behind the cladding. We shingle-lap each piece—sill pan under the window, side flashing under the house wrap, and head flashing over the frame—so any moisture is directed down and out. This keeps the wall dry. In North Vancouver, where coastal storms can force rain sideways, this overlapping method is crucial for pressure-equalized rain screen walls.

The sill flashing design includes a back dam that stops water from wicking inward, while end dams prevent lateral movement. The head flashing is angled to shed water and is installed behind the water-resistive barrier. This way, water flows onto the face of the siding, never behind it. This engineered drainage system works with the cavity behind the cladding, allowing the building envelope to handle moisture, even during the long wet weather common in North Vancouver.
