"I highly recommend Insulation Inc. They provided a timely and thorough quote for insulating my garage attic. Their team arrived on time and upon completion walked me through their work and provided pictures of areas I could not see. The crew cleaned up after completing the job. The Insulation Inc. crew was professional and delivered quality work."

"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!"

"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."

Insulation FAQs, answered by experts

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

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.

Insulating ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

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.
