Foundation Repair

Your home sends clear warning signs when its foundation is failing. Cracked or buckling walls, uneven floors, and stuck windows and doors are telling you that your foundation has been damaged. Let TerraFirma help you maintain your property value.

Basement Waterproofing Icon

BASEMENT WATERPROOFING

Clogged footing drains, hydrostatic pressure, soil settlement, and a cracking foundation are all common causes of water damage in the basement. Let TerraFirma help restore your peace of mind with our optional monitoring system designed to make sure your system is performing and maintained.

 Crawl Space Repair Icon

CRAWL SPACE REPAIR

Your crawl space can play host to a number of problems that affect the value of your home and your quality of life, from mold and pests to wood rot to poor air quality and more. Let TerraFirma ease your worries with our optional 24/7 monitoring system for peace of mind.

Concrete Repair Icon

CONCRETE REPAIR

Cracked, uneven concrete around your home not only detracts from your home’s curb appeal and value, but it can also pose dangerous tripping hazards. Let TerraFirma help improve the safety of your property.

 Earthquake Retrofitting Icon

EARTHQUAKE RETROFITTING

Many older homes in the Pacific Northwest have failing foundations that can buckle in an instant, and even minor seismic events can cause your home’s foundation to shift. Let TerraFirma help you ensure the safety of your home.

I could not be more impressed with how informative, respectful, and honest Bailey was with my parents. He took a very stressful and emotional time, and eased their fears and took the time to really explain and educate them on the best option for their property. I am so grateful!

This company is the gold standard for those interested in maintaining the health of their home. I tell you, ‘My home will never be the same’: The garage is level; We are earthquake proof; And, the will no longer be mold or mildew in my crawl space.
The best part was, not just the satisfying outcome of the work done, but meeting & working with Walter. He talked to me so that I understood why parts of my home were on a downhill slope to disrepair. He drew illustrations so I could visualize each point he made: He was upfront & honest in his assessment of my 1972 home built in clay. If Terra Firma is the gold standard- Walter sure is the diamond. Get your free evaluation today & don’t forget to ask for Walt.

Bailey, was a real professional. He explained everything so that even a 15yr old would understand.
I'd hire him in a minute.

We had a great experience with TerraFirma. The crew that waterproofed our basement were Aris, Manuel, and Cristian, and they were super pro and cleaned up everyday after work. This crew was just great, they were friendly and worked hard every day. Give these guys a raise!

Quinten, the service technician, did an amazing job of servicing the pumps and the dehumidifier, he thoroughly inspected the encapsulation system as well.
He is very knowledgeable about the whole system and answered my questions.
He gave some options for 'shipshape' warning system as well as 'Aspen Air 'purifier' both of which I intend to move forward with.
Your company is fortunate to have hired this quality of personnel.
I am equally satisfied with the original encapsulation crew.

Seriously, if you want a company that's honest and reliable, this is it. They deliver on their promises, no doubt. Trey, the estimator, was super professional, punctual, and a pleasure to deal with right from the start. And Sammy in the office was a lifesaver with all the paperwork and scheduling.

Then there's Goevany, Diego, and Artura – those guys worked their butts off, barely even taking a lunch break in that crazy heat. I can't say enough good things about them; they were awesome, knew their stuff, were total pros, worked hard, and left the place spotless every day.

I'm definitely hiring Terrafirm again and recommending them to everyone.

These guys were all wonderful. Extremely hard workers. No mess left behind and there was a mess, but not in my house. It was all over the guys. But they also cleaned up good! Great work and cleaned everything up beautifully. Don't know where they were out of. Think it was Tigard.

Quinten was awesome. We weren't home when he showed up. I though we would have to reschedule but Quinten waited and was very pleasant about our delay. He made sure everything was working and explained the system to us. Thank you Quinten for coming out today and sorry again that we were late. Will recommend always to friends and Family.
