POOR AIR QUALITY

Humidity and condensation in a crawl space are 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 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.
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.
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.
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!
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.
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!
My encounters with TerraFirma have been great so far. During an initial "inspection"/quote for a few potential projects, they mentioned how their company had been born out of a desire to provide exceptional customer service where other companies in the field were not, and I feel it really shows. The information I was provided was well-explained and never felt like a sales pitch - simply information presented to allow me to make the decisions I needed to. It also came from someone who seemed like they had hands-on experience in the work, not just a representative in a uniform. I also received no "pestering" beyond this appointment, which I appreciated - I get that follow-up is a way that business try to hook new work, but the company I'd gotten a quote from two years prior still calls and emails me to this day, which gets annoying. That same company had also quoted me a price quite a bit higher for the same work, so despite someone commenting to me that TerraFirma was "the pricier option," their offer was a fantastic deal to me.I went ahead with scheduling the first project, crawlspace drainage and sump pump installation. The work was done well and cleanly, and communication throughout and after was great. I definitely plan to contact them again when I'm ready to tackle some higher-cost projects, and feel I don't need to bother with quotes from anyone else to know I'll be getting great work for a competitive price.
We called TerraFirma with a pretty significant problem. We had just purchased a home and were a bit misled on a couple of items. The basement and crawlspace were mold infested (which we did know). What we did not know was that at times of the year, there would be some standing water in the crawlspace. We also didn't know that the drain from the sump pump was actually underwater (adjacent lake), nor did we know the pool backflushed into that same line and actually would enter the crawlspace whenever that process occured. The crawlspace was unvented and unconditioned....the perfect storm of BAD! Our goal was to first remediate the mold and then resolve the issues that allowed the mold to grow in the first place. Enter Terra Firma. Tulane and Terra Firma stood head and shoulders above every other company I spoke with. It wasn't jus that they were going to fix it- we literally walked through every step and every product-I knew what I was buying before we started. The crew was professional, on time and did exactly what they said they would do and in the time frame promised. With Terra Firma, we waterproofed and encapsulated our crawlspace, we insulated the crawlspace, we installed new sub floor drainage with new sump pumps with battery backup to lower the water table under the house (that now drains above the high water line), we installed new structural floor posts where others had rotted, we installed a bypass for the pool overflow and we installed dehumidification and we are in the process of now conditioning the space. Terra Firma led the way and did an excellent job both on the communication and on the installation (at the price originally quoted!). I would highly recommend this firm for anyone with complex and challenging crawlspace issues. Great work and fantastic team from start to finish!Bruce McKee
Fernando and Eddie did a great job on our dual crawlspace project. Our floors are level, structure secure, and crawlspace is clean and pleasant - almost human livable! Wish we had done this sooner!
Marcus from Terrafirma came out to service the crawlspace waterproofing system arriving right at the scheduled time. He was very friendly, courteous and professional. I highly recommend.
