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.

Bryon and Michael did a great job finishing up our hillside retaining walls, making them sturdy and looking finished. They cleaned up the job site and left us with a well-done project. Hope to work with this crew again as we continue with crawlspace waterproofing later!
We couldn’t be more thankful for Terra Firma and our experience with them! We bought our first home recently and our partially finished basement flooded repeatedly over the winter causing a lot of damage, stress and worry. We had a few quotes from other companies who didn’t seem entirely confident it was a fixable problem. From the moment Terra Firma came out to give us a consult they were timely, professional and took the care and time to explain all our options and how each of them could work to fix our problem. The crew worked for 3 days straight to dig through our slab, place in ground piping and set up our sump pump , fixing our flooding problem and they kept us informed the whole way. We felt very confident in their fix and the stress relief alone has been an amazing feeling. On top of that they took complete ownership over talking with the city about permitting issues and ensuring everything was up to code. We can’t recommend them enough! Thank you all!
My mother-in-law’s house was built in 1962 and has had basement water issues for more than 40 years. We’ve spent so much money trying to fix it over the years, but TerraFirma Foundation Systems completely transformed the situation—it feels like magic. Thank you to the team: Casey from sales and the crew members Antonio, Jessi, and Casey. The three musketeers worked efficiently and truly operated as a team. Thank you for bringing such an incredible change to my mother-in-law’s home! One suggestion for management: please focus on bringing happiness to your customers rather than worrying too much about potential lawsuits.
I had crawl space waterproofing performed under my home. It was a two day job. Timothy and his team of Jonathon, Jesse and Moi did a remarkable job and finished as advertised. This entails literally the removable of hundreds of pounds of deteriorated insulation (and other garbage left by the builder) and then encasing the whole area in plastic sheeting. A really dirty job in a VERY restricted work space. Yet, both nights at cessation of work, access from the outside of the home to the crawl space door was left without a hint of mud or residue from underneath the house. At the end of the project, Timothy explained the entire procedure and showed me photos. It looked like a skating rink - bright and white! At $14,000, the procedure is not cheap, but since our home was built on a subterranean spring, necessary. But after seeing all the effort by the workers and the amount of material drug in and out of that crawl space, I definitely got my money's worth. Kudos to Timothy and his team and I highly recommend TerraFirma.
Our house is over 100 years old and the basement was very humid. I had laid down a vapor barrier but it wasn't sealing out all the moisture from the walk-in crawlspace. So we decided to have our walk-in crawl space encapsulated by Terra Firma after getting quotes from 3 companies. I knew that we needed a pro to get all the weird angles done correctly. We chose TF because they were professional, communicative, and their quote was reasonable in comparison to the others. They got the job done and have stayed in contact afterwards to make sure everything was correct. As a homeowner, I appreciated how they listened to my issues and expectations while also giving me needed expertise about how to get the job done. After the encapsulation was finished, the difference was clear. Our home smells better and the air is nice and dry.
Thank you so much! You guys did a great job on the basement. It was not an easy task to remove the foam off the wall but they did it! Everything was left cleaned! Amazing workers! Special thanks to the crew men:Tim C., Johnathan H., and Jairo T.
Our basement waterproofing job was completed on schedule the crew was professional and easy to work with. When we have other foundation or concrete work to be done TerraFirma will be our first choice. Jonah was a good coordinator and everything went smoothly,
Jaden Torson advised me on the best solution for my crawlspace. He was willing to work on picking up and correcting the poor work a previous company had left. He understood the need for a correct, clean space in order for a kitchen rehab to happen. The company made great efforts to arrange schedules so my work could happen in an efficient, timely manner. All staff were very pleasant and professional. They did exactly what was promised and I highly recommend them. It is so relieving to have someone like Jaden who is trustworthy, practical and honest. I’m very pleased!
We had our crawl space waterproofed with a sump pump installed by TerraFirma. Our experience with this company was excellent. Sammy was our coordinator and kept us advised throughout the process in a very thorough and efficient way. Christian was the foreman in installation and Antonio and Jesse worked with him. They all were such hard working and super pleasant young men! They let us know what they were doing all the way through and cleaned up each day, leaving everything tidy. We are very satisfied with TerraFirma's work and recommend them highly!
We were very pleased with the results of waterproofing our basement. James Taylor (foreman) and his crew (Byron Butler and Jonathon Heredia) did a great job! The communications and explanations that James provided were excellent, and the job even got done earlier than expected.
Terrafirma waterproofed our basement. Ryan did a great job managing the job. Actual costs met estimate. Basement is dry since over a year - we are super happy.
Brought the TerraFirma folks in to waterproof the basement. Incredible job and service. Very professional crew (Antonio, Felipe, and Orion) who worked hard and explained every detail. The scope of the project changed slightly and the explanation was informative and made sense. Highly recommend.
