48 years of experience

For more than 30 years, Houle Insulation Inc., a Minnesota based insulation contractor, has been re-insulating homes in Minnesota just like yours. A better insulated home is more energy efficient, comfortable and quiet. It will save you money on utility bills for years to come. And, by using less energy to heat and cool your home, you reduce the negative impacts on the environment caused by energy use. Houle Insulation Inc. specializes in re-insulating existing homes; sidewalls, attics, bypass sealing and blower door testing in the state of Minnesota. Blowing cellulose insulation into your walls and floors, and sealing attic bypasses can reduce high heating and cooling bills, ice dams and drafty rooms. Some other problems homeowners are faced with are frost, mold and water damage to ceilings. The discomforts of a poorly insulated home are often wrongly blamed on furnace and air conditioning problems when the actual cause is the insulation or installation of the insulation. You could save significantly on your heating and cooling bills by having attic bypasses sealed and insulating your walls and attic to adequate levels.

"These guys are the best. My 100-year old house never had much insulation in the attic and after a problem with ice dams in 2019 I decided to get the attic insulated. Houle was on the list of CenterPoint-approved contractors. They came when they said they would, did the work quickly, explained what they had done and cleaned up. They processed my rebate application for me too. My heating bills noticeably dropped last winter, and now that it is warm my house has stayed cooler longer. This summer, I had some water damage on a bedroom ceiling and wondered if the insulation work had somehow disconnected a pump for the AC unit in the attic. Houle sent techs out the same day to check. It turned out the pump had died on its own. The two techs took the time to do their own investigation of what the problem was, and did so cheerfully. Houle stands by their work and takes customer service seriously. I am impressed."

"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."

"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."
