"We had a small job to remove/replace insulation that may have been soiled in our attic from a squirrel that got up there years ago. It was mentioned in our home inspection. After going up to take a look, Sean explained he didn’t see any soiled insulation but there was a small area that had been moved away from the corner and it was effectively empty. It was really too small a job though to warrant them coming out to blow stuff in so he recommended just taking a leaf blower up there to redistribute it evenly. Brilliant idea! He also graciously took a look at our crawl space and identified some areas we should address but ones we could do on our own. He was great to talk to and very helpful and reasonable. So nice in these days of everyone trying to upsell everything. If and when we need insulation work, we’ll be calling Dr. Energy Saver! Thanks so much, Sean Becker!"

"I hired Timberland to remove old existing blown-in insulation and replace with new insulation to R49. They were fast and effective and had the whole job completed within 4 hours. Would hire again."

Insulation FAQs, answered by experts

The ideal temperature for your garage in the winter is between 40 and 68 degrees Fahrenheit. Maintaining a minimum temperature of at least 40 to 50 degrees is crucial to prevent pipes, liquids, and other items from freezing. Low temperatures can also drain your car battery, so keeping the garage stable is vital for your vehicle. While the lower end of the range protects your belongings, the higher end is based on your personal preference for a comfortable space. If you struggle to keep the temperature from dropping below 40 degrees, consider installing a garage heater.

The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.

If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.
