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.
"Todd is amazing. He came to give me an estimate and found the leaky window in my basement that was causing cold air to be the problem for my kitchen sink/plumbing. He suggested I caulk myself and was so pleasant. It was totally free and they did not need to do anything. I offered to pay him for his time and expertise, he said NO. So great to have a company like this. Believe me, if I ever need some real work done, they are the people I would hire!!"

"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."

SERVICES ALL AREAS. OFFERS UP FRONT DIAGNOSTICS IN PLACE OF ESTIMATES.
"The chimney was installed improperly. They put it through my roof instead of out the side of my home. When we have heavy rain, water comes down my chimney and floods my basement. I have complained about this since it started happening. Two years ago they sent out two guys who claimed that the water was coming from not having gutters. So they had a company install gutters. Wrong...only two downspouts in the back of my home only. None in the front, so they overflow when it rains. I told them that the gutters did not solve the problem of my basement flooding ..they told me that they will not fix the situation. Dan Roberts actually hung up on me. I contacted my representative, and he told me to report them, which I will be doing. This has been going on since 2012. Also, they are extremely condescending and disrespectful, as are their vendors. I also talked to the company who installed the furnace and now they are not returning my calls. Centraire is the heating company that installed the furnace. Sustainable Resources gets government money, but should not be in operation."

FAQs for spray foam insulation projects in Lakeville, MN
Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
