Today, we continue to operate with the same core values we established in our humble beginnings: Quality, Honesty, Integrity, and Reliability. These core values encompass everything we do, and shape the way that we do it.

Allied Waterproofing, Inc. has evolved from its beginnings in 1990. We started our business with and continue to serve the Puget Sound area with surface water management installations. We also perform water and drain pipe location and inspection with our interior camera system. Structural repairs in basements and crawl spaces are also an important part of our service to the properties around King and Snohomish Counties. Typical repairs include foundation footings, support post replacement, and general foundation stabilization.

We strive to continually provide our customers with the personal attention they deserve, and pride ourselves on being prompt and reliable. Once we start on your project, we stay working on it until the job is finished and you are satisfied. The Allied Waterproofing crews have many years of experience in constructing drainage installations with the least amount of impact on your property and routine.

All of our work is guaranteed for an appropriate time period that depends on the scope of the project, so you can rest assured that you have made a solid investment in your home by choosing Allied Waterproofing and Drainage. We look forward to the opportunity to provide you with a quality drainage solution.
