POOR AIR QUALITY

Humidity and condensation in a crawl space is a recipe for disaster. Excess moisture leads to mold growth, wood rot, and foul odors, causing issues for your home’s health, air quality, and value.

After removing any organic materials, making sure your waterproofing system is working correctly, and installing vent covers, you should still consider other airborne hazards that fortunately can be prevented with the use of a dehumidifier.

From Roseburg to Eugene, Portland to Seattle, our Foundation Repair work speaks for itself

We hiredTerraFirma to waterproof and redo our crawlspace. We live on a hill which means the crawlspace is on a hill, I am sure it wasn't the easiest place to navigate to get the work done. Heather was the projects coordinator and kept us informed of every step of the project, which we really appreciated. Fernando, was the foreman, and his work crew Felipe, Jorge D., and Jose H. were exceptional workers. This was a three-day project and they were always punctual, very polite, and worked extremely hard getting the project done. Everyone did an outstanding job, and we would recommend the workers and TerraFirma to anyone. Extremely pleased with the workmanship and the project was done on time. The McIntyre's in Oregon City
Mr. Stanford did a thorough inspection of our crawlspace and gave us the honest opinion that very little needed to be addressed. He was very professional and clearly very experienced. This was after a competitor came out and tried to convince us we needed an $18,000 encapsulation.
Had Seth Cunningham out this week for an estimate in Thurston County. We appreciated how thorough he was during the inspection and in creating the proposal.Seth was prompt, easy to work with and very professional! Unfortunately, full encapsulation of our crawl space was a little out of our budget as new homeowners, but if you are looking for any foundation or crawl space work done on your house we would definitely recommend having TerraFirma out to look at your place! I got the impression they are a top-of-the-line company that would take care of the homeowners they do business with. I would absolutely recommend them to friends and family... Also plan to call them out if I have any concrete or foundation issues in the future.
Our 50's ranch sits on solid sandstone, and we've always had ground water running underneath and puddling, making the house damp and keeping us chasing mold and mildew. We figured there wasn't much we could do. But last spring during heavy rains, the old positive flow drain at the bottom of our large crawlspace collapsed and allowed three feet of water to accumulate, destroying the water heater and missing the suspended furnace by a half an inch. We stuck a temporary sump pump down there but it ran constantly and we were afraid to go away even for a few days. A brief power outage would have us biting our nails wondering if the crawlspace would fill up again. Finally we called TerraFirma. The house has a weird layout with odd additions here and there, but they came up with a plan to capture as much ground water as possible and route it to a three-way backup sump pump system. The team arrived and in one day had the drains and sump pit dug (out of solid sandstone, yet!) and the pump system installed. The crew was fast, polite and efficient. They even pointed out a plumbing leak I didn't know about that wasn't helping the situation at all! Now, for the first time in thirteen years, the crawlspace is dry--really dry, no more puddles, no more mold, the house is so much more pleasant, and we don't have to worry about going away or power outs. And if and when we decide to sell the house, we can assure potential buyers that they won't have to worry about dampness or flooding. The service plan is transferrable, which is even better. We were very impressed with TerraFirma and would recommend them for hard-to-solve water issues.Update September 2020: Went to refi the house and the TerraFirma treatment was a big plus for us!
Terra Firma does annual maintenance on our crawlspace drainage system. This year, Marcus did an especially thorough job, spent extra time inspecting and cleaning all the vital parts of our system. Highly recommended.
I had a positive experience with vapor barrier application to my basement walls, a draining system install that wraps around the basement walls, installation of a sump pump, foundation crack repair, sealing/ vapor barrier install in a crawlspace.
TerraFirma recently completed our crawlspace encapsulation.Project went exactly as laid out. No surprises. I've been down there twice since completed and never in prior 12 years. A shout out to Sammy (Project Manager), Tim Cranley (Foreman), Spencer Hunt, Felipe Jimenez, Jorge Diaz and Robert Carmona for all their time, efforts, professionalism, attitudes, etc.. It was a job well done and the staff was great. TerraFirma also did our settling front porch at a rental property in Olympia, WA. Raised it approximately six inches. That also went just as planned.Thanks for that, too.
I was referred to John from Terra Firma when I was looking to have our foundation inspected. John was very friendly and knowledgable and came out to our house to measure and inspect everything. In the end he was able to put our mind at ease and did a great job of explaining different scenarios and what he was looking for.John even inspected the crawlspace while he was out and provided great feedback there as well. Overall we got a lot of good information and never felt as though we were being pushed into unnecessary services.I will certainly be reaching out to Terra Firma for any future needs!
We had mold issues under our house. TF was chosen to encapsulate the crawlspace, remove insulation and put in a dehumidifier. The job was difficult due to more dirt removal required than anticipated. The field team was excellent. They worked extremely hard, were neat and very friendly. They did a terrific job in a difficult situation. TF gave us a date for the work and arrived as planned and stayed on the job until completed. They dealt with us honestly and with integrity. Very satisfied with the solution, the results and the process of working with TF.
We had Tyler from TerraFirma come out to bid fixing a standing water issue in our crawlspace. He was thorough (crawled the entire crawlspace), knowledgeable and responsive to questions. As a real estate agent having access to good contractors is vital, and his professionalism has placed TerraFirma solidly on our short list.
