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!!"

"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."

Your radiant barrier can last up to 80 years or more with minimal maintenance and care. Factors like the quality of the materials you choose and proper installation affect its actual lifespan. Hiring a radiant barrier professional ensures that it's installed correctly to prevent exposure to moisture and other elements, which will help extend its effectiveness.
Installing a radiant barrier in your home offers several benefits that improve energy efficiency and can lower your electricity bills. Mainly, it reduces cooling costs by reflecting heat away from your home, helping to maintain lower indoor temperatures. In the winter, it can help keep warm air from escaping. This reduces the stress on your HVAC system, potentially extending its lifespan and reducing energy consumption.
Additionally, a radiant barrier can protect roofing materials and structural components from extreme temperatures. Pairing your radiant barrier with other insulation systems will provide even more benefits.
A professional installation of a radiant barrier takes one to two days, while a DIY project, due to its complexity, extends the process into several days. The installation duration depends on the size of the attic and the chosen method. For larger homes, experts complete the work in two to three days. Laying foil over existing insulation is a faster procedure that maintains high performance, ensuring the barrier operates efficiently.
A radiant barrier must be installed over existing insulation rather than directly underneath it, ensuring that an effective air gap is created for optimal heat reflection. An adequate air space on at least one side permits the reflective surface to work at peak efficiency, reflecting heat away from the home and preventing moisture issues. This placement method enhances insulation performance and maintains structural integrity by reducing heat transfer and condensation risks, ultimately preserving the quality of both the barrier and insulation.
