We are very pleased with the job that Mike & his crew did on stabilizing our fireplace.
Fixed the problem and cleaned up the site well.

Crew did very fine job stabilizing sinking corner part of my house thanks to Mike and his colleagues.

Bailey came out and gave us a quote on some crawlspace waterproofing. He was very knowledgeable, professional, and a pleasure to work with. He was insightful and gave several good recommendations, ultimately putting together a great quote for our work with a couple of different options. I would highly recommend giving these guys a call for your next project.

Excellent work on transforming crawl space. The experience with Terra Firma was outstanding from our first meeting with the technical specialist Andrew Fry through the completion of the project. The work crew was courteous and professional and did a fine job. Thank you Terra Firma!

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!

They did a very professional job.when there was a small problem a month later they returned and set it right at no additional charge. Punctual, Professional and Prompt.

Working with Walt is always a win. He has an incredible depth of knowledge when it comes to this industry but what really sets him apart is how well he communicates that knowledge to clients. He takes the time to break down complicated issues in a way that actually makes sense—no fluff, just straight-up useful info. My clients felt informed and confident thanks to him, and that’s invaluable. Highly recommend!

Polite, Prompt ,Professional…..that about sums it up.

Fernando and his crew did an amazing job. They were very mindful of cleaning up after themselves, and Fernando explained and demonstrated everything so I could understand.

Everyone at TerraFirma has been great. From the initial bid to finishing the job, they are a top notch company with top notch people.

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.

Very professional start to finish. Ours was a small project in Hood River and they gave me confidence all throughout and finished well.
Thank you

Jorge, Juan and Manuel did an amazing job. They were punctual, they completed the job in exactly the agreed time and left the job site clean. We couldn't ask for more.

They did great work!!

I was very happy with every aspect of the project. Communication, information and work ethic. Kevin and his crew were great!

My wife and I have an old house that needs work done in the foundation. So I called Terra Firma, and they sent Seth to look things over and help us come up with a plan. We enjoyed his visit and were very comfortable having him in our house. He gave us some great options, and he followed through on his word with a prompt quote and follow-up call. Although the time isn’t right for us, we definitely feel that we can trust them to do good work. Thank you Terra Firma!

The floor in our shop is nice and level that the door closes so nicely. before the door would not close at all. This is the second time that TerraFirma has helped us out of a sunken floor!

Giovanny and his team (Diego and Arturo) really did an amazing job! They explained carefully what they were going to do, answering all my questions. The quality of work was first-rate. When they were finished everything was cleaned up to the extent that you couldn’t even tell they were here.

Excellent team! Great attention to detail. Courteous, eager to please!

Very well knowledge on there job. Works quick and efficient. Kept the dust down in my front room.

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.

Contracted for sidewalk and patio leveling and Crack repair. Schylar being the person in charge. Very professional and provided excellent results with final product.

My Husband and I had to have a pretty big job done, the hard working people were always respectful of our home and did a great job.

Both Jorge and Juan who did the install are both wonderful. Even showing photo details before then afterwards and explaining everything in detail. You can’t even tell that they had to use the crawl space inside the house. Everything was covered and cleaned up beautifully. Thank you Jorge and Juan for all the hard work you both did.

Great job Thank all you guys TerraFirma👏 keep going

Jonathan Heredia, Brandon, Jonathan, Lucas and Kameron recently did work on our crawlspace and they did and outstanding job. Very professional! I would highly recommend them and TerraFirma for any crawlspace work.

They did a fantastic job on the entire effort. Thanks So Much

Fast response. Courteous, professional employees in all areas of the company. Clear explanations of what needs to be done to fix the problem.

Seriously….friendly, efficient, professional , will absolutely call them for any future work I may need!

Very professional and pleasant. The work was well done, looks great!!

The guys that came Jorge, Juan, Manuel, Luis, Wesley, Miguel to do the trenching and sump pump install were amazing. Very courteous and hard working. They went over and above to keep things clean and finished the job in a timely matter. Don the sales guy was great as well.

A fantastic company,staff and did excellent job on my house.

Travis and his crew did an excellent job. They were out here and started the day they said, and they finished the following week on the day they said. They kept me informed throughout the project as well as every morning they put down (new) protective plastic in the house where they had to go through and picked it up every night. They did one heck of a job and now I have no worries about water under my house. FYI, the electrical is completed and now all I can do is smile when I hear a Pump kick on. Thanks

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!

We reached out to a few local companies before deciding to go with TerraFirma for our basement waterproofing. Their solution was straightforward, well explained and competitively priced.

We had a sump pump installed along with a waterproof membrane and dry track along the walls. Their team found a way to put the sump pump under the stairs so it was accessible but out of the way.

I had a few concerns that I brought to their attention after the project was finished. They went above and beyond to make sure that everything was taken care of. I appreciate that they really stood by their work.

Since the waterproofing was finished we had torrential rain (that previously would have left standing water) and our basement remained bone dry. The peace of mind has definitely been worth it.

A great company to deal with

Very happy with the results. The actual workers were tops. Only negative was the planning with the utilities. NW naturals said gas should have been turned off during lift.

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!

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.

Robert and Elijah did an excellent job of jacking up my slab where very professional and it was spotless when they finished highly recommended
