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."

Insulation questions, answered by experts

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

If you have blown-in insulation, using an insulation vacuum will quickly and easily suck up all the insulation. Many come with built-in HEPA filters for added safety. While some people suggest breaking up large batts and feeding them into the vacuum, this can expose you to more fiberglass fibers. With batts and rolls, carefully removing them and placing them into garbage bags is a better process.

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

In most cases, the building code in your location will determine the minimum amount, in R-value, required for your home's walls, attic, and other spaces. For attics, the minimum R-value amounts start at R30 in the south, R38 in mild climate locations, and R49 in northern states and cold western areas.
