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!!"

Owner operated. Also services Sherburne & Stern counties & portions of Chisago county. Also serves Northern MN. Award winning. Additional email - info@lewisinsulation.com. 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."

R-value measures how well insulation resists heat flow, which directly affects your home's energy efficiency. The higher the R-value, the better the insulation. By calculating the R-value needed for your specific climate and home design, you can choose the right insulation materials and thickness to keep your home comfortable and reduce heating and cooling costs.
You don't need to remove your old insulation before adding new insulation, as long as it's in good condition. Adding new insulation over existing materials can improve your home's energy efficiency. For example, you can install blown-in insulation around fiberglass batts or place rigid insulation over existing layers to enhance the overall R-value. However, if your current insulation is wet, moldy, or damaged, you should remove it to avoid health risks and maintain optimal performance.
Installing insulation typically takes five to twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the type of material and your home's layout. If you need to remove old insulation, have a larger home, or hard-to-reach areas, the project may take longer.
The International Association of Certified Home Inspectors has said foam board insulation can last up to 100 years if properly installed. Some insulation materials can suffer from water damage or start to sag over many years, thus reducing their insulating ability. Foam boards shouldn't suffer from sagging but have the potential to get damaged. Any broken pieces of foam board can reduce its insulating effectiveness.
