Very efficient and professional!

We called TerraFirma with a pretty significant problem. We had just purchased a home and were a bit misled on a couple of items. The basement and crawlspace were mold infested (which we did know). What we did not know was that at times of the year, there would be some standing water in the crawlspace. We also didn't know that the drain from the sump pump was actually underwater (adjacent lake), nor did we know the pool backflushed into that same line and actually would enter the crawlspace whenever that process occured. The crawlspace was unvented and unconditioned....the perfect storm of BAD! Our goal was to first remediate the mold and then resolve the issues that allowed the mold to grow in the first place. Enter Terra Firma. Tulane and Terra Firma stood head and shoulders above every other company I spoke with. It wasn't jus that they were going to fix it- we literally walked through every step and every product-I knew what I was buying before we started. The crew was professional, on time and did exactly what they said they would do and in the time frame promised. With Terra Firma, we waterproofed and encapsulated our crawlspace, we insulated the crawlspace, we installed new sub floor drainage with new sump pumps with battery backup to lower the water table under the house (that now drains above the high water line), we installed new structural floor posts where others had rotted, we installed a bypass for the pool overflow and we installed dehumidification and we are in the process of now conditioning the space. Terra Firma led the way and did an excellent job both on the communication and on the installation (at the price originally quoted!). I would highly recommend this firm for anyone with complex and challenging crawlspace issues. Great work and fantastic team from start to finish!

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.

Great service from all involved; from the appraiser, the office and crew. Thanks especially to Dennis and Travis.

Terrafirma is an outstanding company.
They know what they're doing.
I highly recommend them.

We have had thoroughly excellent service from TerraFirma since October, 2017, for a variety of issues involving flooding and foundations. TerraFirma seems to us completely competent and reliable. We would recommend this company to one and all.

Terra Firma Foundations did an excellent job encapsulating my Vancouver home’s crawl space: is now now clean, well-insulated, rodent-free and moisture-free. The crew was absolutely OUTSTANDING: Jorge Valencia plus Juan and Manuel. They worked in very cramped space with many obstacles (ductwork) to maneuver around, and they were skilled, efficient and a pleasure to work with. Five stars for the company and the crew. .

We are impressed with the knowledge and thorough and professional assessment of our home’s issue. Seth Cunningham was great at communicating information and providing answers to our concerns.

We had Riley Andal at our house to consult on a settling foundation. Riley was courteous, professional and knowledgeable. With no pressure, Riley followed up over the next few days while we explored our options. When I would reach out for clarification of industry terms and procedures, he responded quickly with good answers. He never down talked the competition, only positive promotion of his company. If you request a quote from TerraFirma in the greater Tacoma/Auburn area, I hope you get Riley as your consultant.
