Get matched with top basement waterproofing pros in Willernie, MN

"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."

"This company is amazing. I would highly recommend them for anyone seeking to evaluate their own home or to look into future home purchases. I have a 100 year old home with several challenging drainage areas, that are hard to address. I really appreciate the way they thought through the problem holisitically and helped me to come up with a a reasonable plan. They also helped me to avoid some advice by a Basement Repair firm that would have not been helpful."

"I appreciated the accurate estimate for the work as well as the advice on preventing it from happening again. The crew arrived on time and raised the walkway section so it’s level now. They also caulked between the driveway and garage slabs."

"Sandau Construction recently completed a window replacement project at my home. They were one of five contractors that I had out to evaluate my project and bid the job. The sales presentation was low pressure, comfortable and offered adequate time for question and answer. The company’s subsequent follow-up to the various questions and issues that I had was prompt, direct and informative. They never tried to “sell” me anything and focused solely on my desires and priorities. Their overall project pricing was competitive overall, versus the other contractors who visited. Pricing was clear and upfront and included no promotional games or gimmicks. With any major home improvement, one doesn’t want to overpay just to ensure quality. The Sandau Price to Quality dynamic was right where it needed to be. Given the high home improvement demand that has been experienced during the pandemic, along with supply chain issues, there was a very lengthy delay from the project down payment to the actual commencement of the job. Once underway, the project installation proceeded quickly. Installers were skilled, agreeable and proceeded in an efficient manner. The final results exceeded expectations. As window replacement is a major investment and expense for any homeowner, getting that all important comfort level from the contractor you’ve chosen is critical. I felt good with my initial selection and was also rewarded at the project’s conclusion. I highly recommend the company to anyone who is interested in a high quality experience in sales, service and product offering. Thanks both to Graham in Sales and to Stephen my Project Manager. Well done."
