Advanced Insulation and Environmental Services is a veteran owned, full service insulation and environmental services contractor for commercial and residential clients with over 30 years experience in the home improvement industry. We are one of very few insulation contractors that are 100% focused on our core competency; creating healthy and energy efficient homes and businesses. We don't do roofing, window installation, HVAC or various construction projects on the side. We use only the highest quality materials available and are an ICAA (insulate.org) registered contractor. We don't believe in high-pressure sales tactics. In fact, we don't even believe in Sales Reps. Every visit to your home and cost estimate will come from a uniformed company owner. We also guarantee that we will have a company owner on-site for every project during the entire time that our team is at your home or business and we never outsource projects to sub-contractors.
"We have an old 1930’s house that was very poorly sealed and insulated. We had the Advanced Insulation team come in to vacuum out the old attic insulation, air seal, and blow new insulation in to code (R60). They were able to increase the air tightness of our home by nearly 25%. We have an ecobee smart thermostat which has allowed us to compare performance before and after the install. Our furnace now runs 15-20min/hr vs >40min/hr on average before, and the heat distribution in the house is noticeably more stable (typical cold and warm spots are less extreme) Kory was very prompt in all communication, and delivered as promised and on schedule!

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!!"

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas.
Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.
Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered.
Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.
Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency.
If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.
Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed.
Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.
Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer.
Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
