"This firm did a great job for me. They were very prompt did what they said they would do. Added insulation to the Attic to get up to R 49. They fixed a few baffles in the Attic as well. Cleaned up after themselves. The pricing was very competitive. No hassles or strong arm salesmen. I would strongly recommend them for blown in insulation work. Jason was very professional in his handling of this project."

"Tim and Jeff were very fastidious in setting up, cleaning, and making sure the house was in good order when they left . We also had an Aeroseal treatment which followed with James and Connor. It did take some time to set up after the vents were cleaned and blown out, but the application of this polymer to close gaps in lthe galvinized steel ducts was remarkable."

"They were very professional and thorough. They helped us solve multiple issues with mice in attic, poor ventilation and not enough insulation. They replaced the fiberglass insulation with cellulose, air sealed the attic and properly vented the attic. They answered all our questions to our satisfaction and explained the process for the project in detail. Highly recommend!"

Insulation questions, answered by experts

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.

DIY installation is not recommended, as professionals ensure even distribution, proper sealing, and compliance with building codes.
