Get matched with top foundation drain installation pros in Algona, WA

"Drain Pro Plumbing Inc guys were awesome throughout the whole process. Would Recommend."

"Excellent work, all around! The crew was hardworking, and the work performed has stood the test of time. Three years ago, Wu Construction expertly installed a full crawl space perimeter footing drain, brought in drainage gravel, and installed a 1/3 hp sump pump. Also installed a 6 mil black vapor barrier, checked and sealed alle entry points to prevent rodent entry, re-installed all loose inulation and replaced heat duct insulation. The crawl space has remained bone dry, and we've had no further issues with moisture or rodents."

"They were prompt, efficient, kept to the time limit so the cost was very reasonable. They did the best they could to clear the drain even though it was a tough one."

"Excellent! Chad did an extensive evaluation of our foundation and put together a comprehensive plan. He is very professional and knowledgeable. All my interactions with TerraFirma were positive and I highly recommend them."

"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."

"Fixed my foundation. Thank you"

"I have a 1906 cottage in N Seattle, with an old porous foundation. Water came into the basement for the first time in 20 years. Another contractor bid the job at $12,000 after 3 site visits and almost a month. Andy came out to the house the same day I talked to him, and estimated the same job at half that price. He followed up with questions, asked about making another visit, came out again and saw that the drainpipe was disconnected at the top of the area being flooded. 75% of the roof's water was pooling against the house. He found a ladder and fixed it and isn't charging me a dime. So, no French drain, no Delta drain, no foundation treatment, no 50' of trenching, no $$$. Andy was timely, reliable, did what he said, and knows his stuff. He was a great communicator, and I feel so so lucky to have found him."

"The estimate provided a clean and competitive estimate. After property owner decided to hire the company, job is scheduled to start a few days later. This is very impressive in consideration of busy season in the summer. The plumbers took a few days to work thoroughly on all items to bring all the plumbing to code. The owner has personally waited for county inspectors twice at the job site. The county inspector commented the job was performed very professionally. Love to refer Knockout Plumbing to friends."

"We hired Rome for concrete slab pouring and gazebo assembly and installation, and he delivered exceptional work that went far beyond our expectation. Front the start, his communication was incredibly fast, often responding within minutes and he maintained that same high level of responsiveness throughout the project. He arrived exactly on time was highly respectful of our property and made sure to clean up thoroughly before leaving. We couldn't be happier with the results. See attached pictures"

"They did a great job on my concrete installation project!"
