    We were really happy with the work that Stephen and his crew (Gage and Ben) from Terrafirma did for us, which included installing SmartPipe, a Smart Sump Pump, and a Vapor Barrier. We were expecting the job to take at least one full day, but it only took them 4 1/2 hours. They were professional, friendly, and courteous..and really hard workers. We were impressed!

    Customer Review

    By Carey
    Portland, OR

    I looked at several crawl space encasement companies at the Portland Home and Garden Show last year. I choose Terrafirma because of the extensive knowledge I got at the show. The crew that installed the encasement was excellent. Stephen, Ben and Gage were professional, efficient, and extremely capable. When a problem came up with the Smart Jacks, they were able to explain the problem and I invested in an upgrade with the confidence that it was a necessary investment and not just an up sell. The only problem I had was that the estimator did not evaluate my crawl space well enough to communicate my expectations to the crew. The crew and the production manager, Geoff, however, came back twice to get it right. There was no guilt trips or excuses. The production crew's dedication to customer service and Angie's courteous help over the phones made this experience the best I have ever had with any home contractor. My only advice is get under the house with the estimator and review his evaluation to make sure you are on the same page. Review those expectations with the crew before they start. Then be glad you hired Terrafirma if any problems arise, because they will get it right. Their customer satisfaction is that important to them.

    Customer Review

    By Deb G.
    Eugene, OR

    We've had Terra Firma of Roseburg do 3 different jobs for us, and all 3 times were delighted with their work. Prior to that, a different basement waterproofing company did some work that we were much less happy with. This time, Wesley Johnson's crew waterproofed one last room in our finished basement (we originally thought we could get away with not doing that room, until the torrential rains hit in December & January.) They put in the perimeter drain system, wall coverings, and the raised tile flooring. We're pretty picky campers, so when we were not satisfied with one aspect of the wall coverings, the crew took the effort to re-do it and figured out a way to make it work. It involved difficult contour lines around the basement ceiling, with exposed beams, everything out of square, etc. When they were done it looked perfect. They worked their tails off to 6:30 PM with an hour's commute back from Eugene to Roseburg. We're very happy with the final results. Jason came back the following Monday (concrete had to dry) to finish the flooring. On one part where their stock flooring transition pieces would not work due to height differences, he actually went to Home Depot and purchased a transition threshold that worked a lot better and looks great. He caulked all the gaps neatly (the previous company didn't caulk, just left big gaps around the edges). Overall we're very happy with Terra Firma of Roseburg, and are so glad we found them.
