BasementS WATERPROOFED, HOMEOWNERS HAPPY

We take pride in our years of experience making homes dry, safe, and stable. From Ashland to Corvallis, Beaverton to Olympia, our Basement Waterproofing clients have given us great feedback.

These folks are WORTH the call and having them out! Seth, specifically, was amazing at scope, plan and presentation. He was so knowledge and really took into account all of the needs of the house structurally and visually. He was extremely professional in house and on the phone. Nothing was over sold or up sold, and every concern I had was listened to and taken into account. Every detail was in the bid neatly and nothing was out of place. If you've got a basement or crawlspace project, this is as professional as it gets. I will DEFINITELY be keeping this company in mind for future projects and for friends and family. Call. Ask for Seth. He's got you.
The Crew was great to work with, Region Supervisor did a great job, The lady on the phone was knowledgeable on the job process and has great communication style. The job turned out just has they described, we had our crawl space waterproof.
Thanks to TerraFirma for the 3 young men Jorge, Juan and Manuel who encapsulated our basement. Always on time, working a full day and at the end of it all doing a wonderful job. Our basement has never looked or smelled better.
Thanks Michael
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.

Seth from TerraFirma came out to my house to inspect my basement, which is starting to show signs of water encroachment. I had no idea what to do. He did a thorough inspection of the interior and exterior of the house, and then we talked. He walked me through several options to address the issue, explaining in a way I could understand, and being very receptive and responsive to my questions. He was very professional and courteous. Seth promptly sent me the quotes for the three options we had for the basement, and made sure to be tidy as he headed out!

Even before this, the person who talked with me on the phone to take my info, and later to confirm the visit, was helpful and courteous.

It's rare to have a such a positive experience with a contractor (just sayin'), but this was it. I am not sure when we'll be making these changes to my basement, but when we do, it'll be with TerraFirma -- and it'll be with Seth. Everything about this company is green flags!
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.

I had a consultation with Riley for some water damage in my basement. He was courteous (took his shoes off before coming in the house), informing and on time. It seems like this team has great communication and I will use them in the future should the need arise! My issue was a smaller drainage problem and door framing issue that needs to be addressed by a different specialty.
With a water floored basement, we contacted Terra Firma to locate the water source which they did in no time. They explained, in detail, what would be done to fix the problem and went to work. They were respectful of our furnishings covering to protect them from limited dust. They were professional and the project was completed on time. We are very satisfied with the end result, quality of workmanship, and price. We would recommend them for foundation work of any type.
