Crawl Space Support Posts

When floors in the home start to sag, this may not be a foundation issue but a possible problem in the crawl space underneath. Homeowners in Oregon and Washington are very familiar with the damage our wet, damp, and expanding soils do to our homes. If left unchecked, these conditions can lead to wood rot, mold growth, and pest infestations, further weakening the structural integrity of the crawl space. Poor ventilation and trapped moisture exacerbate these issues, creating an unhealthy environment that can impact indoor air quality. Proactively addressing these problems with crawl space support posts not only protects your home but also ensures a safer, more comfortable living space.

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

We had concerns about the foundation and flooring of the home due to water and moisture in the crawl space. Walt, out of the Roseburg office was very responsive and timely with accurate information for our situation. Ultimately, we decided on crawl space encapsulation. The bid was easy to read and laid out a comprehensive work plan for our home. They were also able to meet our scheduling needs for the timeline of our project.
Bailey Mercer-system design specialist made a visit to my home to provide an estimate for foundation work. He was professional, well-mannered and easy to talk to. Assessment was thorough with all my questions being clearly answered. Great experience overall!
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!
Had an awesome experience from start to finish. I initially worked with Tulane Seville whom helped me tremendously. Very friendly, professional, thorough & kind. He made the whole process go smoothly.

Also Robert marciniak who did the foundation job was great! Hard working, pleasant & explained all the steps to my tenants & I. He even completed the job a day earlier than anticipated. Overall I’m so happy with Terra Firma & their employees. Thank you.
We had Riley Andal at our house to consult on a settling foundation. Riley was courteous, professional and knowledgeable. With no pressure, Riley followed up over the next few days while we explored our options. When I would reach out for clarification of industry terms and procedures, he responded quickly with good answers. He never down talked the competition, only positive promotion of his company. If you request a quote from TerraFirma in the greater Tacoma/Auburn area, I hope you get Riley as your consultant.
Gave me a really reasonable solution to our foundation issue. Great communicators. Easy to work with.
Seth came over and had a look at my foundation to give me a quote on some work. I was incredibly impressed by how thorough he was with his inspection of my property and the knowledge he had to help me assess the condition of my foundation. Would highly recommend
The process of stabilizing my foundation was done quickly and professionally. Permits and reports were provided upon completion. They were a pleasure to work with. The site visits were scheduled in advance and they were always there when scheduled. The final work was completed when scheduled and the site was cleaned up with minimal disturbance. If I had a question, they were always quick to explain the process. A pleasure to work with.
Hey Folks, So just over a year ago we were having some issues at the house, I wrote to all of you on how wonderful TerraFirma was to us and I am here to tell you... THEY DID IT AGAIN! I starting noticing some movement in the driveway and inside the garage again. Called up Bree in the office and asked to have someone come take a peek. Edwin came out, what an awesome dude! Edwin spent a short time at the house remeasuring a couple things to compare back at the office with measurements from a few months ago, We heard from Bree that the measurements were still within reason. I let Bree know, something is not sitting well with me and I really would like to chat with the Mgr. So I received a call from Tulane, Again SUPER DUDE! Tulane assured me with my husband present that I am not being in any sorts a pain, I have concerns and he and Sam, who came out in 2024 will come to the house.

Well they came, they saw, Oh Boy! I was not wrong, they were here 2.5 hrs and again, the house has had some movement and we need some more work to stabilize. We have some additional C.Y.A's to add to this round, as our neighborhood and home has lots of sand in the soil so we are going to be looking into getting a GEO Engineer out to see what is causing the movement.

I give all the back info, because I want you all to know, if you feel something is not right CALL and have your home looked at. TerraFirma is NOT redoing what they already did, this is all new issues, not their fault at all... Tulane and Sam are amazing, they took the time to explain and give us all options. The info they share through experience and knowledge is beyond me and it is so appreciated.

If you have any foundation, sinking driveways, walkways, stairs, cracking in your walls, around windows, doors.... Call these guys!
I hands down don't always do reviews but I do for these guys because they deserve to have their names out there so you know they are TAKING CARE of their customers the whole way through! 10/10 and then some.... THANK YOU!
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.
