"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."

"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

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.

Bubble wrap is better for moving since it can be cut to size, whereas dish foam comes in precut sheets that are harder to manipulate. However, if you’re packing items like dishes, wine glasses, picture frames, or mirrors, dish foam will protect them better. Ensure you measure your box beforehand so you know what size dish foam to purchase. 

How to dispose of insulation depends on a few factors, including the condition of the material. While you can simply bag up and throw away many kinds of insulation, some municipalities offer recycling, so it's worth checking with yours. If there are contaminants such as asbestos in your insulation, abatement and specialized disposal are often necessary.
