"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 "

"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!! "

Lewis Insulation Inc
Lewis Insulation Inc
Owner operated. Also services Sherburne & Stern counties & portions of Chisago county. Also serves Northern MN. Award winning. Additional email - [email protected]. Additional contact name - Nancy Lewis.
"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."
