"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."

"I recently had the pleasure of working with Koala Insulation of St. Paul for the installation of 4 inches of spray foam insulation in my garage attic, and I couldn't be more satisfied with the results. From the outset, Koala Insulation impressed me with their professionalism and expertise. Their team was punctual, arriving on time for the initial consultation and installation. They took the time to explain the benefits of spray foam insulation, including its superior air sealing properties and energy efficiency compared to traditional insulation materials. This thorough approach gave me confidence in my decision. On installation day, the crew was efficient and respectful of my home. They came fully prepared with all the necessary equipment, and I appreciated their attention to cleanliness. They took care to cover areas that needed protection, minimizing any mess during the installation process. The actual application of the spray foam was quick and straightforward, and the team worked collaboratively to ensure a high-quality finish. After the installation, the team provided useful guidance on maintaining the insulation and what to expect in terms of performance. They made themselves available for any follow-up questions, which shows their commitment to customer satisfaction even after the job was completed. I highly recommend Koala Insulation of St. Paul for anyone considering an insulation project, including upgrading or replacing your current fiberglass insulation. Their timely service, knowledgeable staff, and high-quality workmanship resulted in a seamless experience will undoubtedly improved my home's comfort and energy efficiency as we head into the cold season. If you're looking to enhance your insulation, look no further â Koala Insulation is a solid choice!"

"Professional and courteous. The folks on site took time to answer any question, wore masks and cleaned up well. They did great job painting the stucco after insulation and patching - house looks great. The insulation is already making huge difference in my 1911 house in Minneapolis- not sure the boiler will kick in till December."

"Ivan came out to replace our garage trim due to squirrel damage and did a fantastic job. He was timely, responsive, and easy to communicate with where I had questions. Very easy to work with Ivan. Squirrel crisis averted and garage looks very good - high quality job by Ivan. I also had Ivan look at an ice damn issue we have been having on a section of our home. Ivan assessed the insulation, showed me the issue with lack of insulation (there was only 3 inches) and the building standards, gave me a fair price on insulating, and a week later he has insulated this section of our home. I am confident this will take care of our ice damn issue. I also could not believe this was not caught when we bought our home and again had insulation checked by a company last year after paying $3000 in ice dam removal. We are very thankful for Ivan?s expertise. Ivan stands behind his work and will help if we have additional concerns. I will 110% leverage Ivan in the future at our home."

"John and his team did amazing work removing the old, insufficient insulation in the attic of my nearly 120 year old home and replacing it with a much higher R-value blow-in insulation. The difference in the look of the attic is phenomenal, and I am confident it will be good for the energy efficiency of our home as well. The entire project took around 8 hours and the team even cleaned up to the point where you could hardly tell any work was done. I found dealing with John and Spray Foam Insulation Systems to be a very pleasant experience. Very honest and forthright, while offering a very fair rate for the work. I highly recommend working with them."

"Ryan did our estimate, and was very efficient. Andrew and Evan did the insultation work and did a fantastic job! It was a large area to get prepped and then to insulate and they did a great job every step of the way! Our entire home is now at a R50+ insulation level, as opposed to the R25-30 and 0 values we had before. It will be interesting to see what sort of impact the newly insulated garage and 3 season porch has on the comfort level in the main house. The team did a great job for us and I would recommend them to anyone considering insulation!"

Insulation questions, answered by experts

Sometimes you may be able to leave the bags with your regular trash. However, that’s not always the case. Call your local waste management prior to starting the removal and ask about the proper ways to recycle or dispose of removed insulation. In many cases, your town or municipality has a designated dumpster for building waste.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

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.
