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.

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 foundation support posts to distribute the weight of your 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. The heavy-duty threaded rods of these crawl space support posts 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

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 demonstrated exceptional attention to detail and expertise when inspecting the house foundation, ensuring everything was up to code and structurally sound. He addressed the issues I was concerned about and was very honest on his findings.

I hired TerraFirma to do a seismic retrofit on my house. The entire experience was outstanding! They showed up exactly when they said they would. The job was completed in the expected time and they cleaned up after themselves.
I feel like the cost of the project was more than reasonable for the peace of mind l now have, knowing l have done what l can to protect my home in the event of an earthquake.
I would recommend them to anyone who is looking for a professional company to work on their foundation.

Brian Comunale was incredibly thorough in his inspection and assessment of my compromised foundation. He took pictures of all the damage and explained the issues and possible solutions. He went above and beyond. Truly phenomenal communication and customer service. I highly recommend his services.

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.

Great work. I had huge foundation issues on a large waterfront project. Terra firma waterproofed my basement and lifted the house on hydolic piers to level it out. They saved my project. Seth was a fantastic project manager and Oscar and Jorge completed the job extremely well. 10/10 would recommend for any foundation issues.

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.

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.

Terra Firma did a good job shoring up my foundation - they arrived promptly, were good about communicating what was going on. Geovany was a great foreman for the project, with Diego as the main worker, and Sammy kept everything moving from the office. I would recommend them for further work!
