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 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 reached out to TerraFirma Foundation Systems to have them come look at my foundation. They were able to get me on the schedule within the week. Seth showed up on time for the appointment and got right to business. He walked me through what he was going to do and what he was looking for. He was very professional and polite. He even took his shoes off outside everytime he had to come in the house. Which is a big deal to me. When he finished the inspection we sat down and went over all my options. The whole experience was easy and I didn't feel taken. I would highly recommend Seth and TerraFirma.

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 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.

A few days after moving into our home we noted some serious issues with our outdoor drainage.Over the course of just 2 days of rain in the Pacific NW, water was flowing into the garage and crawl space rather than away from the house.We needed an evaluation and a plan asap. Based on reviews and services available, a quick call to TerraFirma was the answer.I had an appointment within a few days. We were very pleased when Seth arrived and explained that, by the end of today’s visit we would have a detailed plan including the cost. As we walked around the entire foundation and yard Seth was open to questions and explained details of what he was noticing. Seth was also taking note of other potential issue that could be avoided with some preventive DIY care.The extensive evaluation resulted in great news. Although we knew it was going to be an expensive project, due to the labor involved, Seth presented an optimal approach for a permanent solution at a fair price.We were very happy working with Seth and TerraFirma.Steve and ToniShelton,WA

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.

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!
