Basement Finishing & Remodeling in Astoria, OR

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include:
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average Astoria contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.

Job Stories From Astoria, OR
Super Sump in Astoria, OR Basement

This homeowner already had a sump pump but realized that it was not working efficiently. She also wanted to make sure her basement was waterproofed because her house was for sale. Our inspector, Daniel noticed that there was water getting into the basement and suggested installing our patented Waterguard system and a Super Sump sump pump.

Once the homeowner agreed to our recommendations Tim and his team quickly went to work. They installed our patented Waterguard perimeter drain system which collects wall seepage and directs the water to the sump pump. Bree chose to have a Super Sump sump pump installed which has a built-in alarm system for when water levels rise too high. It smoothly and quietly pumps out up to 2,600 gallons of water per hour.

Now that our systems are in place, Bree is confident that her home will sell better and that the future homeowners will not have to worry about water issues.

We just bought the house and we have water coming from basement floor and walls in various areas. The basement is concrete/unfinished, aprox. 1000 sq ft and does have a Sump Pump installed. We would like an estimate for sealing / waterproofing or at least water mitigation.

An exterior French Drain has been recommended to us because of exterior drainage issues, but the basement in the house also shows evidence of some water presence, particularly in heavy storms. The basement floor is dirt covered with a vapor barrier.

I am buying a house in Astoria and it is slated to close around Christmas time and it has a leaky basement. I will put a lockbox on the house, but around that time it would be good to have the house looked at/quoted.
