"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

Upgrading insulation offers several benefits, including improved energy efficiency, which leads to lower heating and cooling costs. It also enhances indoor comfort by regulating temperature and can provide noise reduction. Additionally, better insulation has a reduced environmental impact and can increase your home's value and overall livability.

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

Yes, crawl space insulation is worth it if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home. Though you’ll pay more to install insulation initially, the savings you get from installing insulation can help offset those initial costs over time.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.
