Waterproofing in Port Coquitlam
Air & Water Barriers · Deck & Balcony Membranes · Through-Wall Flashing
Nixon Exteriors provides waterproofing in Port Coquitlam, serving homeowners and property managers across Citadel Heights, Lincoln Park, Mary Hill, Oxford Heights and surrounding neighbourhoods. We install the membranes, barriers, and flashings that keep rain out of the wall — self-adhered and fluid-applied weather barriers, deck and balcony waterproofing, and through-wall flashing integrated with the cladding and openings. Port Coquitlam shares the Tri-Cities' high rainfall patterns — which is why the weather-resistive barrier, the flashing, and the deck membranes all have to be continuous and lapped correctly. Windows, doors, and cladding are handled by one accountable crew, with $5M liability coverage and WorkSafeBC compliance on every job.
Why Port Coquitlam Chooses Nixon Exteriors for Waterproofing
Windows, doors, and cladding handled by one accountable contractor — every layer of the wall detailed as a continuous system.
We deliver waterproofing on single-family homes, townhouses, condominiums throughout Port Coquitlam. Port Coquitlam's mix of established neighbourhoods and new developments creates demand for both replacement and new-construction window installations across every price point.
Port Coquitlam shares the Tri-Cities' high rainfall patterns. Windows and doors feature reinforced drainage and sealing systems for reliable wet-weather performance year after year. We specify the waterproofing detailing that handles those exact conditions.
Because Nixon installs the windows, flashing, and cladding, your Port Coquitlam project is detailed as one continuous, warrantied system — no gaps between trades.
How We Approach Waterproofing
Continuous Drainage Plane
Water always finds the path of least resistance. We build a continuous, lapped barrier so any moisture behind the cladding drains back out, not into the structure.
Detailed at the Weak Points
Leaks start at openings, decks, and penetrations. We focus on these transitions with sill pans, end dams, and counter-flashing done to spec.
Integrated with Cladding
Because Nixon installs the barrier, the rainscreen, and the cladding, the waterproofing is never compromised by a follow-on trade.
