Drew was the lead on this project and I thought he is a great asset to the company and crew leader.

I felt that Nate Schattenkerk and his team did a great job the 3 days they were at my house, working very hard with highly professional skills and attitudes.

Chad & Gage performed in a very efficient and professional manner. Answered all my questions, explained the process to my understanding and got right to the job. Even though my job was very small, I felt they were treating me as they would a very large customer. My hats off to both of them. I may be able to refer them to some of my neighbors who are experiencing similar problems to mine.

After initially talking to Chris about the dimpled barrier that directs water to the sump pump that was installed, I thought that it would fit more closely to the ground. It sticks up in spots and does not hug the ground as I thought. I talked to Drew about this and he said it would be OK. They removed the existing vapor barrier from where the dimpled material was installed saying that it takes the place of the old visqueen.

I'm very glad I went with TerraFirma. My crawl space is up to date and I can now sleep knowing that there won't be any water in my crawl space again!

I was so impressed with everyone I met and consulted with from the start through the completion of this challenging project. Thank you so much for your great attention; I felt confident that my house was in excellent hands!

Has been difficult getting final documentation of the project. Project close out seems incomplete. Quality of project documentation is not up to the standard of the sales documentation. A complete O&M manual and warranty documentation with as-built drawings should be included.

We had a nasty crawl space that had been bothering me for a long time. at first, I was really apprehensive about encapsulation. not only was it somewhat expensive, it is not very common. Everyone I mentioned it to thought I was crazy. in the end, I think it is well worth it. now we have a clean space that I can crawl in without a respirator or mask. There will never be another animal under our house again. Thank you Terrafirma. Great job.

Sincerely,

Russ Johnson

I am the maintenance supervisor for the association where the work was done. The home owner was very pleased with the work. Future foundation issues will be done by your company.
