"Had huge foundation problems at a project of mine on the waterfront. We used terrafirma to both waterproof the entire basement AND lift the foundation. 10/10 would recommend. extremely communicative, very knowledgeable, and even brought a crew in from Oregon to help us stay on schedule. Oscar and jorge got the job done extremely quickly and Seth was fantastic as my project manager. "

"4.5 stars overall for removal of concrete slab/stairs and pouring of new 10' long, 4 foot deep foundation wall. Result was excellent. Crew was considerate and trustworthy. It was expensive for me, but cheaper than the other bids I got. Communication was not great over email. There were a number of times I wasn’t replied to at all or got a partial response. I let them know and they said they’ll work on that. I recommend communicating via text instead which worked much better."

"Outstanding work and value. Andy was quick to respond and came out the next day to assess what we needed to do to improve the drainage in our crawlspace. The home is built on a sloped lot. Andy suggested a full perimeter drain install around the foundation. The work also included complete replacement of the vapor barrier. All work was performed efficiently and Andy backed it up with a lifetime warranty. I couldn't be happier with the end result and would highly recommend Andy and his crew."

"Excellent company! These guys did a great job of installing insulation in my attic as well as the removal of old insulation. Also, the clean-up job after the job was great too. The technicians were knowledgeable and friendly. No issue in recommending."

"The workers were on time. Very efficient. They did a blower door test and found the air leaks and insulated these areas. Blew installation above the garage, cleaned out the crawl space and put new installation there and basement. Found a water leak from my toilet,Thank goodness. Covered everything in the basement and swept and cleaned up after. I would recommend them!"

"Initially we had an inspection/estimate done, the inspector showed up exactly on time, quickly went under the hose, photographed the major issues, and showed me everything (I had been under there many times and he found things I never saw). The estimate was exactly what I expected (my neighbor hired them last year for a similar sized house) and the work would take 2 days due to the size of our house. We were scheduled for the next week.The actual work went extremely well, they showed up on time (with a 2 hour commute for them), started right away, the first day they created a corridor of plastic and cardboard/plastic to enclose their access to the outside (this was removed at the end of the day), so odor and debris wouldn't enter the house, they then completely cleaned out all vapor barrier, insulation and other debris, sealed all holes, ducts (with mastic), insulated uninsulated water pipes and ducts. This took about 6 hours, with 3 men. The 2nd day they put the corridor back up, installed all the insulation completed a bit more sealing and laid the vapor barrier. This took about 10 hours. The insulation was actually more tightly and completely hung than the original builder did. The vapor barrier was taped together into one continuous sheet, the original was just wide slightly overlapping strips. Upon completion I was invited down to inspect. All debris was bagged and at the end of each day was removed. Overall the work was very well done, very professional, the crew were courteous, responsive and very experienced. I would highly recommend these folks to others."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Olympia, WA

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
