Our Story

Read More

Northwest Waterproofing was the brainchild of Brad Dowers. As a third generation waterproofer, Brad knows waterproofing. When he set out on his own to make his mark in this industry his goal was simple: become the best specialty contractor in the Northwest in commercial and residential waterproofing. He has cultivated a strong sense of professionalism. NWWP places value on clear communication and guarantees the integrity of each finished waterproofing system.  NWWP provides a wide selection of services from a variety of manufacturers.

With over fifteen years of hands-on experience installing a wide variety of waterproofing systems, and in many cases repairing the failed waterproofing attempts of other contractors, Brad has gained an appreciation for the importance of following manufacturer’s application guidelines to the letter. It is far too costly to return to a completed project, especially if it is below grade, to make repairs. That is why every job we do we do the right way the first time; conservatively, not cutting corners or compromising on proper preparation and detailing. Once we get a contract in hand we don’t care what it takes to do the job right. We just do it. We stay focused on the critical objective of providing a watertight installation every time we walk onto a jobsite. Our technicians are trained to be meticulous, and to be proud of their work. Because you, the customer, depend on it.

Brad has been successful because he has developed his problem solving and troubleshooting skills and honed his waterproofing application methods. When new technology becomes available it is evaluated for its efficacy and affordability. This drive to always be improving applies to all phases of the construction process from estimating, bidding, project management to project closeout. That mindset embodies the values and integrity that Northwest Waterproofing lives by.

Northwest Waterproofing offers a comprehensive array of services in both Commercial and Residential construction, new and remedial. We proudly service the northwestern United States from Newport, Oregon to Bellevue, Washington - and all points in between.
