"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

"Atticare did a thorough evaluation of the home. Because the soffits were in disrepair, there was a pest issue. Atticare did a great job coordinating with the roofers. The old insulation was removed and the area was inspected for pests, cleaned and sanitized. They returned after the repair to make sure all was sealed, and installed the new insulation. They also helped lay down some plywood for some flooring in the space as an extra. Before doing their work, they laid down material to protect the floor and removed everything cleanly. They were efficient with their work and I was pleased with the job they did. The job was priced as quoted with no surprises. Marlon and Luis coordinated the job and were friendly, professional, and experienced."

Insulation questions, answered by experts

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

Spray foam is a highly effective insulative material that can dramatically reduce your energy bills and create a more comfortable living space. It does have a couple of drawbacks, however. First and foremost, spray foam insulation is much more expensive than fiberglass batt insulation. In addition, spray foam insulation is a dangerous chemical material; this is a project that is best left to pros for proper and safe installation.
