Waterproofing in New Westminster
Air & Water Barriers · Deck & Balcony Membranes · Through-Wall Flashing
Nixon Exteriors provides waterproofing in New Westminster, serving homeowners and property managers across Queensborough, Uptown, Downtown, Sapperton 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. New Westminster's location along the Fraser River means higher humidity levels — 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 New Westminster 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 heritage homes, character homes, queensborough townhouses throughout New Westminster. As the oldest city in Western Canada, New Westminster has many heritage homes that require specialized window replacement to maintain architectural character while improving efficiency.
New Westminster's location along the Fraser River means higher humidity levels. Products must include advanced moisture management systems to protect your home from river-valley dampness. We specify the waterproofing detailing that handles those exact conditions.
Because Nixon installs the windows, flashing, and cladding, your New Westminster 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.
