Get matched with top sump pump or interior foundation drains installers in Granite Falls, WA

"Water had always been a problem for my crawlspace, especially during raining and snowing season. Asking around, installing a French drain and a sump pump appeared to be the solution. I searched around and picked Insulation Co. Estimation without inspection seemed weird at first, but it made totally sense since the foundation layout is all there in the files. Jo had always been responsive, detailed and nice whenever I had questions. Scheduling was easy and Rafael and the team did a great and efficient job onsite. 2 months after the installation, we noticed that there was still standing water and they came back to install more pipes and gravels. We really appreciate the effort."

"They did a great job, we had some sewer replacement work done and a tankless installed. We love the tankless and haven’t had a single issue with our sewer since. It was so worth it, and they were quick and efficient!"

"Tyler, Danny, & Juan were friendly, professional, and very efficient. They cleared out all the old insulation and rodent leavings under our house Friday in 4-5 hours. Monday they installed insulation, thick white plastic and sealed up the crawl space with a de humidifier and were done by 3:30pm"

"Installation went great. Very clean and professional and excellent customer service"

"Friendly and knowledgeable staff, but expensive $600 for less than an hour of work to replace a tub drain."

"Had a great experience with WA Evergreen Insulation from start to end. Rob came to my house, quoted me an insulation install, made absolutely sure that they would not cover any existing knob and tube with insulation and prevent a fire. The crew showed up and completed the job in one day. Once they got started it was clear they knew exactly what they were doing - and they managed to shimmy into the extremely small attic access and cleaned up my rat jerky in the crawlspace! I'm very happy with this job and with this company!"

"Great! Also gave good suggestion to help water drain better."

"on-time, great communication, excellent installs, great end result."

"Don't hire anyone else. If you're looking for a company run by someone who understands what customer service looks like, call Perma-Dry. 4 years ago we worked with Perma-Dry to install an internal basement footing drain system - they were prompt, responsive, and did a great job. We've had zero issues. We recently discovered an issue with an old external drainage system (not installed by Perma-Dry) which backed up during a thunderstorm. When I discovered the issue, I called Ryan (owner) to get some help; he showed up at 9am on a Saturday (his day off) and spent 5 hours with me troubleshooting the issue and coming up with a temporary fix until he could get a crew out to install a permanent fix. He not only was a huge help, but his attitude was incredible - he was actually having fun working on his day off. In the 12 years I've owned my house, I've worked with dozens of contractors and never had an experience like that. True customer service is a lost art, Ryan and his team have shown us twice that they understand how to take care of customers and care enough to do the right thing."
