Floor Joist & Sagging Floor Support Systems

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.

SmartJack®

THE SMARTJACK SYSTEM stabilizes crawl space beams and floor joists. It’s the ideal solution to lift the floors above the crawl space toward their original elevation and reduce floor “bounce” caused by weakened floor joists or excessive spans. The SmartJack system addresses weak foundation soils by creating a solid base of engineered fill to distribute the weight of the home. Galvanized steel columns are cut to length, set on a cast aluminum footing and secured to existing girders or supplemental beams with adjustable top brackets. Heavy-duty threaded rods allow for adjustment and can even lift sagging and sloping floors.

  • Provides a permanent solution to undersized beams, rotting, shifting and settling wooden posts
  • Installed by attached steel support beams to your floor joists and a sturdy base at the floor. Once all posts are installed, they are adjusted to raise your floors to a level position.
  • Installs in limited-access areas and its the only crawl space support jack that addresses problem soils
  • Compatible with crawl space encapsulation systems, making it a good choice for homeowners wishing to eliminate moisture problems and improve home energy efficiency

I had TerraFirma foundations repair my crawl space issues, the 3 men that came out to do the job were very professional and cautious. Jorge, Juan B, and Manual J, did an exceptional job and Jorge explained everything that they were doing and showed me lots of pictures during the process. After the job was finished they made sure everything was cleaned and put back together. Than I received a call from the project manager Jonah, to make sure everything went well and he made sure I was happy with the job. I recommend TerraFirma to everyone!!!!!

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.

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.

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!

I love TerraFirma. We had a new foundation with a sump pump and dehumidifier four years ago. First, it is so great having a dry basement! Each year, TerraFirma sends someone to check the sump pump and the dehumidifier. Jeff did the inspection last year and this year. He showed me what he was doing, documented with pictures, answered my questions and showed up on time! This has been my experience with every interaction I have had from the beginning of the project to the follow-up.Here is a picture of the new foundational wall and my workout area.

This was truly an awesome experience, from the time Will arrived to do the estimate, to completion of the job a little more than a week later. Will gave us great insight as to the foundation and build of our home. We were having issues with a back patio and front steps that were added to the property post build and had sunk quite a bitt.All the folks we dealt with at TerraFirm were friendly, informative, helpful and kind. From our initial contact with Hillary to schedule appointments, to our very informative meeting with Will for the appraisal and estimate, and a very special shout-out to Schylar and Jonny, for a very cool learning experience during installation. We pestered them with questions the entire time they were here and they graciously and willingly answered them all! great crew, awesome job and a joy to spend time with.Thank you all for a great experience!!!Michele

Austin was an amazing technician. The scheduling was easy, he was punctual, and the communication was professional. He crawled the entire crawlspace like a champion and even found a little plumbing leak for us. The estimate was provided on site, and I would highly recommend them for encapsulation and other foundation work.

I recently purchased a home that I knew had water encroachment in the basement. Terra Firma came and presented what can be done and I knew it had to be done. Tieran and his crew came in and did exactly what was explained to me. They answered all my questions and I feel very confident it will be a dry basement going forward. I highly recommend this company for any work that needs to be done to foundation, water issues, crawl space etc. Fantastic company!

Our experience with TerraFirma was exceptional from the very beginning. From lifting and leveling our front sidewalk; to stabilizing our garage foundation the experience was positive and the teams so efficient. Sammy our project manager was always available for questions and information. Thank you! Oscar C., Jorge J. And Diego you rock.

I got a bid done by TerraFirma today. After speaking with Seth today. He answered my hundreds of questions and cured and worries I had about foundation issue. He broke it down and explained the whole process from start to finish how to remedy my foundation problems. I like the fact that they were punctual. They were right on time at the scheduled appointment and wasted no time trying to figure out a solution for my problem. The prices He gave to me were really fair and the depth of knowledge was very useful. I feel very confident that TerraFirma should be able to fix my settling / cracked foundation problems.

We have a number of options for repairing and stabilizing crumbling walls. Walls showing cracks can be stabilized with braces custom fit and secured tightly to the walls in question. For walls in really bad shape, our EverBrace Wall Replacement system is a permanent solution.
