"We had insulation installed a week earlier by Koala. During the insulation, Jasper (insulator) suggested another area that we might consider installing blown-in insulation. We agreed and the second job was performed on Friday, the 24th. Jasper and Richard were on time, the insulation project was well done and they left the area very clean. Would use them again."

"We called Mister Insulation and Jeff came out in a day or so. We explained that we purchased new windows and doors and had insulation blowen into the walls but the house was still not warm. He took pictures in the attic and used a thermal camera to show where we were losing heat also we had mold. He removed the mold and replaced the insulation . He and his crew were very professional. We would recommend them ."

"Ducts were sealed quite dramatically from the graph they provided. I am not seeing much savings on heating as I expected."

Insulation questions, answered by experts

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

Although spray foam insulation typically has a higher price point than traditional insulation, the benefits often justify the investment. It offers superior sealing properties, which can lead to significant energy bill savings. Spray foam also provides excellent moisture resistance and soundproofing. Other advantages include improved indoor air quality by minimizing allergens, a long lifespan of 80 to 100 years, added structural strength to the home, and a straightforward installation process.

The time required for insulation installation can range from a few hours to a few days, with most projects taking 1-3 days to complete. The final duration depends on the project's size and complexity, the area size, and the type of insulation being installed.

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.
