The install team kept me informed the entire time, cleaned up after themselves, and left my house as clean as it was when they first came in. And to top it off, the foam looks great, and is performing just how they said it would."

I do all kinds of insulation for your home, from batt insulation to spray insulation, we have more than 10 years of experience offering 100 percent effective quality, we also do driwall if you need a complete service, we insulate your house completely and cover it with drywall.

"I hired Ramon and his team to do my attic insulation. He was flexible with scheduling over two days as we needed to replace ductwork for our HVAC in the attic. His prices were WAY better than anyone in Northern Virginia. He was able to come out in two days to remove all the old and dirty insulation that was thirty years old. The attic was cleaned and air gaps sealed. He came back promptly when we were for the insulation installation. Not only did they do a great job at sealing but they did a great job at spraying 18 inches of R49 Fiberglass. They were professional, timely, and cleaned up after themselves. They went above and beyond my expectations. I am so happy and would gladly recommend these guys for anyone. Five stars!!!"

Insulation questions, answered by experts

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.

Freeze-proof faucets can still benefit from insulation, and they will need covers if you live somewhere with extremely cold winter temperatures. These faucets work with a design that keeps excess water in the pipes inside the home to minimize the risk of freezing, plus a downward slope for any water flowing through the pipes to keep moving. But keeping a cover on all faucets, even freeze-proof fixtures, is the best way to avoid frozen and burst pipes.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.
