Jason has been here for the third year in a row and has done an excellent job on my crawl space. This time because of the ice out over four days in December 2023, he said it would be a good idea to replace the battery. I went ahead and did it just to be safe. I am glad there are people who can go down in that crawl space and check everything once a year. He eve manages the wolf spiders.
I had Bailey come out to do an estimate for crawlspace encapsulation and some drainage work in the basement. Bailey spent 2 hours at the house and on the phone with me in total (not counting the work he did on his own), doing a very thorough work up of the house and patiently explaining what my options were, and what might be better for my renovation contractor to do. I really appreciated Bailey's willingness to think through different options - some that didn't include work for his company - and teach me about crawlspaces!
The crew at the Vancouver, TerraFirma did a great job!! Jacob Iltis did a great job presenting several options to resolve the crawl space issues, the main focus was on a bouncy floor and we opted to install a new beam with screw jacks. Jorge Valencia and his crew, Juan and Manuel did a great job installing the beam and screw jacks. They communicated exactly what was going to happen and when. They put flooring protection down and did a nice job at cleaning up at the end. I highly recommend TerraFirma and the crew of Jorge, Juan and Manuel to get the job done. TerraFirma will be my first call if I have anymore issues.
I had a positive experience with vapor barrier application to my basement walls, a draining system install that wraps around the basement walls, installation of a sump pump, foundation crack repair, sealing/ vapor barrier install in a crawlspace.
Both crew's were on time. The crawlspace crew put down plastic from the front door to the crawlspace entrance in a bedroom. Work was completed on time, our closet doors reattached and the areas they worked in or went through left clean and tidy. The sidewalk crew completed their work in a day and even patched a crack we had forgotten to mention to the estimator. If TerraFirma also did crawlspace insulation, that would have been great, but I had to find another company for the insulation.
We had a complete encapsulation of our crawl space and sump pump and humidifier system installed. The young men who did the work were very professional. Antonio was the project manager and he was fantastic. Answered questions, explained the process, and made sure we were ok with what they were doing. They showed up at the time designated and called if they would be late. Communication was very good. Shout out to his helpers, Daniel, Jesse, and Kameron. At the end of the project they cleaned up the workspace and made sure things were left like it was before project. Thanks guys.
Travis and the crew did an excellent job with our crawlspace project. They were always on time even though they were coming from Roseburg to Bend, and great with giving updates as they went. We love our new crawlspace now and grateful for cleaner air, better temperature regulation in the home as well as the added benefit of extra storage. Thanks TerraFirma!
I had TerraFirma foundations repair my crawl space issues, the 3 men that came out to do the job were very professional and cautious. Jorge, Juan B, and Manual J, did an exceptional job and Jorge explained everything that they were doing and showed me lots of pictures during the process. After the job was finished they made sure everything was cleaned and put back together. Than I received a call from the project manager Jonah, to make sure everything went well and he made sure I was happy with the job. I recommend TerraFirma to everyone!!!!!
I didnt even hire these guys. Im a plumber who came through to fix a repair they found after they redid a crawl space, and they did such a good job i had to come leave a review. Cleanest and most comfortable belly crawl ive ever experienced. The white barrier they use is padded enough i didnt even need my knee pads, and it looks a thousand times better than black visqueen. They even left a little tote under a leak they found so it wasnt wet for me or their new work when i came to fix it. 10/10
We have done two projects with Terra Firma in 2022. One project required using brackets underground to move our chimney back up against the house. The other project was crawlspace encapsulation. For both projects we have been extremely happy with the communications, customer service, pricing and great work staff on site and in the office. Very glad to work with Terra Firma and their people!
I got Fernando, Chris and Jorge to do the install of the encapsulation of my crawl space and they were very professional and fast for the job size.
So we had Jorge, Juan, and Brad do an encapsulation of our basement crawl space and they did an amazing job. The area they had to literally crawl around in to complete the work was incredibly tight yet they completed their work without complaint and with style. It looks great! The work these guys had to do was tough, give these men a raise! They earned it!
