Testimonials for TerraFirma Foundation Systems

The call center and the System Design Specialist, Adam, were excellent. The concrete leveling product was a lot more effective and much cheaper than I thought especially in comparison to the alternative of having things ripped up and replaced. Given a proposal at the time of inspection made it easy for me to make a decision. I signed on the day of inspection. Everyone did a great job and good luck.

TerraFirma was able to schedule everything to my convenience. from the appointment to installation, we were never pressed for time and felt like we were going out of our way to be available. They made sure to be available for us. They are Portland's household name for foundations. We turned our rather large sized basement into a bonus room for guests, the kids, etc. It is what I would consider a daylight basement and we are so excited that we now get to take advantage of this large space. It nearly doubled our square footage.

This is one of our rental properties that we needed to have treated. Eventually we would like to have it completely finished so we can rent it for more and make it livable for more people, but for now we have decided to take care of the waterproofing part. We had a drain system installed around the perimeter of the basement slab. This track collected water, directed to a sump pump and removed. Perfect! Jason put together a very simple design. Since we wanted to get the project completed as soon as possible, we asked our final questions and signed on the day of inspection. Anyone who knows they have a problem that needs to be fixed there really is no other company in town that will give you better service and products in town. Thanks for the quick turn around guys.

Finally a basement area that we can use and enjoy rather than just for storage reasons. Ryan and TerraFirma had everything we were looking for in a total basement finish. Ryan had a very complete and comprehensive description of what I needed to get done to transform my basement into what I had envisioned. There were many different options we could choose from regarding walls and floors. Also, they went the extra mile to order windows, which is a service you guys typically don't do. Thank you for going the extra mile and making sure I was completely satisfied!

Deryl was excellent! did a comprehensive job, explained the issues through descriptions, photos and videos. Overall a very complete and professional analysis of the problem and comprehensive recommendation for the solution at a reasonable cost. The service that we got from the call center was excellent, Deryl was nothing short of that and nor was the installation crew. We never felt like we were left in the dark about the next steps in the process. TerraFirma was very on top of things and we really appreciated being in the loop. Many times in the past the project would start and finish before we had any chance to ask questions. Availability and courtesy means everything to me when it comes to a contractor, and Deryl did exactly that.

On a scale of 1-10, my experience with TerraFirma has been a 10. For larger expenses or home projects, I always take my time to shop around to make sure I am getting the best deal and the highest quality of work for my dollar. Waterproofing my basement was no different. TerraFirma was the first of 4 bids. What I found after discussing the different options was that TerraFirma's proposal was middle of the pack price wise, but by far at the top as far as completeness and total basement waterproofing. I'm very glad with my decision to use TerraFirma's expertise. The entire company from front to back was professional and took great care of me, my time/money and the project. You have a great team at TerraFirma and needless to say I was very impressed with the projects outcome.

I had TerraFirma out to my house for a free inspection. Deryl was professional and informative. He gave me all the information that I needed to make a confident decision. Thank you everyone at TerraFirma for helping me out.

TerraFirma came to our home and helped waterproof and finish our basement. The customer service in the call center and by the System Design Specialist were excellent. Everyone showed up on time and was prepared for the task. After receiving multiple bids we believed that TerraFirma's was going to give us the most efficient solution so we went with them and we are glad we did. They did an excellent job from start to finish.

I was thrilled with the job that was done! Very satisfied and the systems specialist did a great job presenting the scope of work. TerraFirma was accommodating and worked with me to overcome obstacles such as where the sump water would drain.

Gage did a very good job of explaining things clearly when we had questions. The whole crew operated in a very professional manner. Jason also made himself available to us at all times (even on his vacation). I would definitely recommend your company to friends and family.

Every fall, like clockwork, we are going to get a large amount of standing water in our basement. It has gotten to the point that we don't go down there or keep anything in there because we know it will get ruined. What we had TerraFirma do was a total basement finish. They put in drains, a sump pump system, finished looking walls. The whole nine yards. The area is livable and we ended up making the space a bonus room. Jason was prompt to our appointment and made sure that all our questions were answered. He went over an objective checklist to make sure that all of our needs were being addressed in his solution. Jason was friendly and professional. He was the reason we went with TerraFirma.
