"This was our first time using Apollo Insulation and Geremy and Dennis did an excellent job removing our old (rodent droppings and urine) insulation. They disinfected and repaired any damage caused by the rodents. New insulation was blown in and we couldnâ t be happier. From the initial inspection and quote Geremy was on top of keeping us informed on what would be done to complete the job. Apollo Insulation cleaned up behind them inside and outside leaving our home with no mess. The price was very reasonable and we were very pleased and satisfied with the quality of the work. I highly recommend Apollo Insulation for any of your insulation needs. Very hardworking and professional service company. Bill and Anne G Wayne, Maine"

"Andrew and his crew did great work on a tough job at a competitive rate. They installed batts of RockWool in our attic over a couple of hot summer days, carrying big bags of it up our front stairway without scuffing the walls and then getting it through the small trap door in our second floor bathroom into the attic and laying it tightly in overlapping, crisscrossed layers from there. We have an older home and the joist bays are all irregular, requiring careful trimming and fitting of the batts in the ceiling plane. Prompt service, too. I am very appreciative of their work."

Insulation questions, answered by experts

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.

Unfortunately, pipes can freeze when exposed to prolonged freezing temperatures, whether or not you have installed insulation covers. Insulation covers, however, are still an excellent idea as they can reduce the chance of your pipe freezing by keeping the pipes closer to the temperature of the water inside the pipe.

Traditional clapboard siding, particularly with panels made from wood, is not a significant insulator on its own. However, you can keep your home cooler in summer and warmer with "insulated clapboard siding," which is a type of vinyl clapboard siding with a built-in foam insulation. Consult a local siding contractor to determine whether insulated siding is right for your home.

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.

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.
