"Prodent Homes did an excellent job with our attic remediation. They removed the old insulation, sanitized and re-insulated the entire attic. The owner David was easy to communicate. The crew lead Jose was very experienced and communicated well. The job was done professionally. We are happy with the results and will use them again if we have another insulation job."

"Founders Insulation has been the best company I've worked with for this type of project. Brian and his team were professional, efficient, and reasonably priced—especially compared to other quotes I received. I could already notice a difference in my house after the installation was complete. I strongly recommend them to anyone looking to insulate their home or business. You will not be disaapointed. Brian is very kind and easy to work with. I will use their painting and drywall services in the future for my home. Thank you so much for the great work."

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."
Owens Corning ProPink R-49 Blown-In Insulation. Our most popular product
These vents help your attic circulate air. With attics reaching over 120 degrees in the summer these are very important. They prevent mold and increase the lifetime of your insulation. Most other contractors miss installing these.
Look at the difference! Our foam is fire-rated which allows us to air seal around penetrations that contractors never could before.
Most homes have penetrations all over there attic. Imagine trying to blow up a balloon with a bunch of holes. It will never fill up. Now imagine trying to blow up your house with air conditioning and heating with a bunch of holes in the attic. It will never fill up.
Recessed can lights are notorious for leaking air. Recessed can light covers help with air-sealing your living space and prevent fires.

"I selected this company because they are a member of my energy provider's energy saving program network. The customer service was top notch and the insulation installation team was top rate. There was a problem with the aeroseal team assigned to seal any holes in the air vents. The aeroseal solution leaked throughout the house, even into drawers, closets, on clothes, everywhere. It took over a month to clean up. Throughout this process, the owners remained in contact and assisted as best they knew how. The cleanup was stressful, but in the end, all worked out and I have noticed an improvement in energy savings. Thanks!"

Insulation questions, answered by experts

Water heater blanket prices range from $20 to $40 on average, though you typically won’t need to spend more than $30 for all the tools and materials required for installation—which include the blanket itself, heavy-duty scissors, and electrical tape. Blankets with higher R-values will also be slightly higher in price.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

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.

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.
