Basement Finishing & Remodeling in Portland, 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 Portland 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.

Leaking in daylight basement at foundation - when it rain heavily
Vicinity of N Amherst St. in Portland
I'd love a quote to seismic retrofit the house. Thanks!
Vicinity of SE Pardee St in Portland
Have a approx 20x10 crawlspace in a basement I would like pricing to encapsulate
Vicinity of in Portland
We don't think our house is bolted to the foundation. We are planning some remodel, and the contractor has given a price for this, but we think it may be higher than it should be.
Vicinity of in Portland
We have discovered a strange damp spot in the middle of our basement - doesn't seem to be connected to any pipes... may be water seeping in from the ground after heavy rain? It's starting to warp a piece of base board on an interior wall. Would appreciate it if someone could come take a look at it and see what the problem might be. Thanks!
Vicinity of North Ida Avenue in Portland
Hi there! I wanted to inquire about drainage solutions for my yard in the St Johns area of North Portland. We've noticed moisture in our basement (no puddles or big leaks, just humidity and condensation on concrete walls) and would love to find the right solution to help with drainage along the exterior of our home to prevent it from becoming a larger issue. Curious to learn more about french drains, and if your team does sloping and grading. Please reach out via email or phone at your earliest convenience.

I want to schedule routine maintenance on our sump pump.

Water seepage into basement. After heavy rain there appears to be water under the basement laminate flooring. It has not pooled to the point of being visible on top of the flooring, but the boards are warping and there is a 'squish' sound when you press on some boards.
Vicinity of in Portland
We have had a moderate amount of dampness in our partial basement for years. Recently, we have seen a small puddle of water in one area and we wonder if it was connected to our recent heavy rains. We would like to have the crawlspace checked for dampness as well.

Vicinity of NW Village Heights Drive in Portland
We have a 10'x10' crawlspace the needs to be checked out. It will need new insulation and check for mildew, rodents, etc. Will likely need a vapor barrier put down, but may already have some visqueen in place. Thanks!
