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.

Encapsulation and consistent maintenance don’t just protect against crawl space moisture problems—they also retain a stable temperature in this area, improving indoor air quality and reducing allergens. Over time, this can prevent costly repairs caused by worsening structural problems or degradation. Additionally, a well-encapsulated crawl space boosts your home’s resale value; ultimately, it is a wise investment for homeowners intending to stay or sell. So have Terra Firma fix your crawl space problems today to start reaping the benefits.

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

We had a fantastic experience with TerraFirma Foundation Systems! Their team quickly and accurately diagnosed our foundation issue and clearly explained multiple repair options, which helped us feel informed and confident in our decision.

Once work began, they oversaw everything from start to finish with professionalism and great communication. The crew working in our crawl space was hardworking and efficient — they did a great job installing a French drain and sump pump, and left the area clean and well-organized.

We really appreciated how smoothly the whole process went. Highly recommend TerraFirma to anyone needing foundation or drainage work!
Sam was able to provide an excellent inspection and honest report of my crawlspace waterproofing needs. Didn’t feel rushed or pressured. Was able to educate me to better understand the issues and risks. Thank you so much Sam
So we had Jorge, Juan, and Brad do an encapsulation of our basement crawl space and they did an amazing job. The area they had to literally crawl around in to complete the work was incredibly tight yet they completed their work without complaint and with style. It looks great! The work these guys had to do was tough, give these men a raise! They earned it!
Travis and his crew were absolutely outstanding. They were very friendly, clean and neat during the process. They informed us of a leak that we had no idea about. Saving us costly damage, we truly appreciate it.
I had to go in the crawlspace since they completed the job. Absolutely amazing! Prior to them completing the job, whenever I had to go under, I was 50% sure something was going to jump out and kill me. Now, I feel I can easily camp out there with confidence.
Thanks guys, Amazing!! Money well spent.
Wish you all the best, for all your hard work.
Elijah did a fantastic job breaking down everything going on in my crawlspace and providing the estimates to get the repairs.
The Terra Firma team of Luis Juarez, Jose V., and Jorge D. were very dedicated and thorough in the crawl space encapsulation project at our home. They worked long hours to get the project done well and on time- as promised.
I had Bailey come out to do an estimate for crawlspace encapsulation and some drainage work in the basement. Bailey spent 2 hours at the house and on the phone with me in total (not counting the work he did on his own), doing a very thorough work up of the house and patiently explaining what my options were, and what might be better for my renovation contractor to do. I really appreciated Bailey's willingness to think through different options - some that didn't include work for his company - and teach me about crawlspaces!
Inspector Elijah was on time when he said he was going to be there was very prompt and personable. I feel like did a very thorough inspection of my crawlspace.
I don’t usually do reviews but in this case people should know this is a first class company. Great communications and no selling you on something you don’t need. John was very professional, he spent time with us expanding what issues he did find, measured the level of the floors, inspected under the house and checked wall and foundation cracks. He also placed a blanket down to collect any dirt from entering and exiting the crawl space inside the house. I highly recommend John from the Eugene office and TerraFirma.
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.
