TerraFirma Reviews and Ratings

Check out reviews and comments from our past customers.

Our experience with TerraFirma was great from beginning to end. They were very fast, efficient, clean and courteous. We had the crawlspace encapsulated and our whole house smells and feel better. No more mold and bowed floorboards. And they were cheaper than the competitors.


One of the most professional and courteous businesses I have worked with in many years. The level of communication from them was outstanding from beginning to end and very much appreciated. It's a rarity to see a business today with the customer service values we used to see long ago!

McMinville, OR

Overall very professional, customer oriented, clear in explanations of what is needed. Both salesperson and crew were very pleasant and easy to communicate with.

I wanted to take a moment to let you know what a fabulous crew you sent to our home. We had crawl space trenching and sump pump installation done at our house on August 5-6. Wesley and his crew of three guys did the work.

I was very impressive by the crew. They were very professional, polite, and pleasant to have around. The work they did was difficult, as our house has rock under it in some places. Regardless, they did a thorough job, hammering through the rock in several locations. Wesley suggested a pump discharge location that was visually much better than the one I had in mind, even though it required extra work and pipe.

Finally the clean-up the crew did was very thorough. They wiped down door handles, swept, and cleaned up every stray rock. One crew member even asked if I could use any extra rock in my landscaping and filled in one area beautifully.

You never know what you are going to get when you have work done at your home. I am very glad that we chose TerraFirma and will definitely recommend you, should anyone I know need your services.

Everyone we dealt with from Ryan to Dana and Kieth in scheduling then the crew that came and performed the work was very professional and well informed to the job at hand.

Carson, WA 98610

The crew was awesome! I stopped to talk with them, and they walked me around and showed me what was going on. The crew impressed me! The lead was there the first day but not the second. The guys that came over the second day - it was a seamless transition! They were there, did the job and left. I didn't get a chance to thank them to that extent to let them know that they did such a good job, I was impressed! They did great!

Issaquah, WA

The sales rep was super professional, courteous, punctual, and knowledgeable. His advice was very practical. I could tell his main concern was doing what was best for our needs, not simply doing what he could to make a sale. We feel very comfortable with his recommendations and look forward to working with them in the future. I highly recommend this company!

Bellevue, WA

Fantastic! The people you sent were very pleasant, just got the job done, very nice, and they got to it! I couldn't have asked for a better crew!

I appreciated receiving the booklets on foundations and crawl space. They made me very confident that TERRAFIRMA was the best company to meet my crawl space needs.

Stephen is always on time, calls an hour or so before to give us a closer idea of arrival time. Knowledgeable to explain techniques, options we may have a close approximate costs of needed professional repair required to improve our devastation and prevent further/repeat problems. Feel welcome to let us visit with possible clients and share answers to the questions.
