Crawl Space Condensation, in BEAVERTON

Had Seth Cunningham out this week for an estimate in Thurston County. We appreciated how thorough he was during the inspection and in creating the proposal. Seth was prompt, easy to work with and very professional! Unfortunately, full encapsulation of our crawl space was a little out of our budget as new homeowners, but if you are looking for any foundation or crawl space work done on your house we would definitely recommend having TerraFirma out to look at your place! I got the impression they are a top-of-the-line company that would take care of the homeowners they do business with. I would absolutely recommend them to friends and family... Also plan to call them out if I have any concrete or foundation issues in the future.

Great; competitive price, installation went great, friendly and responsive staff in person and office. They made a drainage system for our crawl space with a sump pump.

Mark Johansen was very thorough in inspecting our sump pump, VaporLoc and performing a general inspection of our crawl space, providing pictures of every concern. He then made repairs to all of the areas discovered and went above and beyond in service!

Bailey did a fantastic job inspecting my crawl space and designing a solution that fit my needs. I really appreciated his thorough evaluation, detailed explanations, and professionalism. I will keep TerraFirma in mind for future projects.

I purchased two waterproofing systems from them a few years back. After the rain the past couple days its time to leave a glowing review. They did an interior drain in my basement and a separate drain tile system in my crawlspace. Both systems have been working flawlessly for 3 or 4 years now with zero water intrusion into my basement that I totally renovated after their install. They've also come out every year as promised for servicing. Thankful for connecting with them. After hearing the river of water enter into the pump and it go off every minute or so for nearly 12 hours yesterday, they deserve 5 stars. I would recommend them to anyone.

Elijah did a fantastic job breaking down everything going on in my crawlspace and providing the estimates to get the repairs.

I was very happy with the work that was done on my crawl space fixing drainage problems and putting a sump pump in. They also put in metal plates around the crawlspace exterior walls. The young men were very nice and they kept me informed. They were also very careful to keep my inside floor clean. (The only entrance to the crawl space was inside my house.) My neighbor also used them when her floor had some problems. I am happy to recommend them.

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.

We're very happy with the TerraFirma experience. They were easy to contact, on schedule, on budget, friendly, professional and approachable. They are the best team we've encountered out of all the contractors we've worked with to repair and improve our home. From the initial consult with Ryan, to the steady project management of Sammie, to Tim's installation crew, they were a seamless team. I have serious health problems and it's easy for me to become overwhelmed with tasks or fail to remember important dates and activities, but Sammie was so gracious and helpful that I didn't feel anxious for a moment. When the team came to overhaul the crawl space and install the sump pump, I was prepared for pet drama, but the team were like ghosts. Even my stupidly anxious rescue dog was calm because it was so quiet. Tim was super helpful with all of my questions during the installation, and when the project started to fall behind he added another man to his team the next day, rather than risk going over the 2 days of work Ryan had estimated. Tim, Chris, Jonathan and Jairo were like extremely polite ninjas that just quietly disappeared beneath my house. When we did interact they were easy to talk to and were able to answer all of my questions. I will absolutely recommend TerraFirma to my family and friends. They do great work and made the whole process much easier than I could have hoped for.

We had our crawl space waterproofed with a sump pump installed by TerraFirma. Our experience with this company was excellent. Sammy was our coordinator and kept us advised throughout the process in a very thorough and efficient way. Christian was the foreman in installation and Antonio and Jesse worked with him. They all were such hard working and super pleasant young men! They let us know what they were doing all the way through and cleaned up each day, leaving everything tidy. We are very satisfied with TerraFirma's work and recommend them highly!

***Please note -- I updated my review from 1 to 5 stars. Terra Firma took the initiative to reach out and assess any next steps needed to correct the problem. Trust is 100% restored knowing that if problems come up they will take any action needed to follow up. I will also say that the work they originally did was actually to code, and we agreed that the moisture problems arose due to the nonstandard setup of my dehumidifier, NOT because of errors in Terra Firma's work. Thank you Terra Firma.*** Unfortunately, I have to drop a negative review in the interest of warning other folks that their work has gone downhill. I previously had an excellent experience with Terra Firma for management of a water problem in my crawlspace. I hired them without question again for my current property for management of moisture issues, and I didn't check their work upon completion as thoroughly as I should have. Unfortunately, about 1 - 2 months after completion of work, I discovered a large mushroom growing out of one of the structural posts in my crawl/basement. On closer inspection, I noticed that the dehumidifier water discharge line they installed was dumping less than a foot away from my foundation, corresponding to the exact spot the mushroom was growing. Moisture was the exact problem they were supposed to fix, but now they have created a severe structural problem secondary to moisture with the dehumidifier line dumping large quantities of water right next to my foundation. In other words, they created the exact issue they were purporting to fix by collecting the moisture and depositing it into my foundation. Once fruiting bodies are growing out of wood, this is an indicator that the wood is severely compromised and the fungus network has grown extensively. I now have a very expensive and serious problem to fix. I called to let them know about the problem, not sure if I will hear back from the coordinator/ the team who did the work. I am not sure if I would trust them to fix the issue after the damage they have caused, but I would accept financial remediation. If they take steps to make things right, I would update my review. I would not hire Terra Firma again for any crawlspace work, be it structural or moisture related because of the big problem they have caused. Again, just would like to warn others.

Just had clean out of old duct work and old insulation, etc. plus encapsulation of my crawl space. The crew worked really hard and professionally throughout the 5 day process and the foreman kept me informed along the wife. Have worked with Terra Firma on several occasions: pier placement and jacks for house, french drain in crawl space, and replacement of sump pump, etc - alll involved from the estimators, the office personnel, and work crews have been excellent throughout.
