"I got several estimates from several providers. The pricing seemed just ok with those other providers but something seemed off. Good Life came in and made sure that I was getting the correct amount of insulation (where the other service providers had under estimated) and helped me to get into a loan through the utility company for the cost of the insulation. Good life is a qualifying contractor for this and it saved me a lot of out of pocket expense. They came in and did what they had to do. They were professional and made sure the work was done well."

"Very professional company. From the initial contact, inspection and quote by Brian, to prompt scheduling follow-up by Jessen and arrival of the team, everything went seamlessly. Would definitely recommend this company. Jabari and Anthony did a great job insulating the rim joists, adding wall and pipe insulation under the sink on an outside wall and caulking a leaky window - no more breezes. Definitely feel a difference in the house now. The added attic hatch cover makes the heat stay below, where it belongs. Really appreciated the use of PPE when they were working with mineral wool. Very satisfied customer here."

"Ecofoam insulated my attic with closed-cell spray foam and the results came out great. The space feels completely sealed and much more comfortable already. Sevi and the team were very professional, easy to work with, and kept me updated throughout the whole process. I would highly recommend EcoFoam for anyone looking for quality insulation work."

Insulation FAQs, answered by experts

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.

If the outside temperature drops below 20 degrees Fahrenheit, it will take around six hours for your pipes to freeze—and they might even burst. That’s why keeping your mobile home’s temperature around 50 to 60 degrees Fahrenheit is necessary, even if you’re leaving it vacant for the winter. In addition, having ample skirting around the mobile home's underbelly will help keep pipes insulated during the winter. 

For your safety, you should always wear a mask when cutting batts of fiberglass insulation. We also recommend wearing eye protection, safety gloves, and long sleeves to protect your skin. Properly suiting up helps you avoid several fiberglass issues, such as cuts from the tiny shards of glass and inhaling small bits of fiberglass.

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.

The cost to rent an insulation vacuum ranges between $250 and $350 per day. The price will increase if you choose to rent for additional days, but you may get a discounted daily rate if you rent it for a whole week, which could cost up to $1,000. Once you've removed the insulation and are ready to replace it, the cost to rent a blown-in insulation machine ranges between $100 and $500.
