Get matched with top basement waterproofing pros in Champlin, MN

"The patio extension looks nice and was completed quickly for a good price. My only complaint is that with the wet weather the day before they left behind some significant ruts in the lawn. I'll have to rototill and re-seed those areas later this summer."

"Beware: Overbilling, bait-and-switch, and Miscommunication I hired Groundworks (Saint Paul, MN) in June 2025 for a combined structural support and waterproofing project at my home. The project was advertised as a complete solution to address foundation wall deterioration and structural support. What happened: The contract and engineered plans explicitly called for cast-in-place (CIP) footings for each I-beam and a vapor barrier. I paid for these as part of the $70,000 project. After the work was completed, I discovered the CIP footings, vapor barrier, and other items were not installed, despite being billed and included in the plans. The installed I-beam system does not support the weight of the house, only lateral wall movement. This was not explained during the sales process. When I asked for clarification, I was told ?site conditions vary from the plans,? but no specific conditions were identified. Revised as-built plans were submitted instead after I raised concerns "

"This job was completed efficiently and professionally. A design specialist came to test and measure every detail for the project. The crew arrived with everything needed for the job. They worked very hard to install Waterguard in the concrete floors inside around the foundation to the sump pump basket. They also installed Geo-lock anchors to support a block wall that was bowed. This company has 36 years in business and provides excellent results and professional customer relations. Call Amer. Wtrwrks for a free estimate. You will not be disappointed. A wise investment of $11,270."

"Project was completed very efficiently and cleanup was complete. Marc and Brandon were outstanding. I would recommend them and the company to anyone needing this type of work done. Very satisfied."

"Safe Basements have been a complete joy to work with, the customer service was professonal and friendly. The assesser was honest, no up selling or down selling. They finished the project 2 weeks after booking. The workmen were effiecent, made sure to cover everything so nothing got covered with dust, they even swept! It got done in exactly the time required and the basement has never looked better. If you need basement work, I couldn't recommend anyone higher."

"Great costumer service! They were honest when giving us a consultation."

"Before you hire any Water Control company hire a plumber to make sure you really need drain tile. After we hired this company we still had seeping water issues. After they were called twice they finally told us we had a leaking pipe. In addition, an employee stole a cellphone and a FITBIT watch from our home and damaged our egress window. They fixed the egress window. The owner was not very pleasant, made us feel like we were not telling the truth. My husband literally spent hours changing passwords and canceling credit cards since the cellphone contained sensitive information. A few days later through Google find my device we pinned the cellphone at this business location, we called the police and had to take time away from our work to retrieve our phone. We never retreived our FITBIT watch. It was a nightmare! The company apologized but the damage was done!! The job itself was OK.. Apologies are not good enough after the hell we went through!! Watch who enters your property!! "

"They completed it in 2 days and I havent had an issue since the basement was waterproofed. However, they did forget to plan the initial inspection prior to the work as part of the permit. The city I live in ended up reaching out near the end of the permit date and I didnt know about it until then. I reached out to the project manager for my project at Acculevel about it and they did handle that issue promptly."

"The project eventually got finished. Might have been a little more complicated to get started on as it required the city and contractor to communicate seeing as it was a city renovation program. Things I?d like to go better is cleanup and mitigation of dust. It was limited to whatever steps I took. The pump has to be reset 1 to 2!times through a span of 60 days or so. Not sure if that?s normal and to be honest I haven?t yet reached out or looked into this on my side. Aside from that Mr Brown was easy to talk to and respectful as was his workers. When the work finally started to was down quickly. There were parts that could have gone better but it could have gone worse. I won?t say I wouldn?t recommend them at the same time I think there?s something?s that could definitely improve upon. And to add it did pass City of Plymouth inspection and their requirements for the program. I?ll have a better idea of how this works out in the future."

"Lewis Insulation came out for work on my home for ice dam issues. Lewis Insulation was to air seal our attic and add insulation. We decided to move forward. Lewis Insulation allegedly performed the work, but unfortunately the ice dam issues persisted. In short, we flushed thousands down the drain by going with Lewis Insulation. Xcel energy performed a home energy audit for us after Lewis Insulation performed the work. The Xcel home energy audit revealed that air sealing was missed during the air sealing process. After confronting Lewis Insulation, the team claimed some of these areas were inaccessible. This includes our furnace flue, which gives off a ton of heat in the winter. For those who may not be aware, this is egregious because of how much heat comes off that pipe. At no point did Lewis Insulation inform me that they were unable to air seal specific areas, including the flue. Lastly, they failed to insulate our basement rim joists properly. In short, we paid to have the team air seal our home and help with ice dams. They failed to eliminate the ice dams, and Xcel suggested we get our home air sealed again. I cannot recommend this company to anyone."
