"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"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."

Insulation FAQs, answered by experts

Yes, covering exposed wires is necessary for several important reasons. Exposed electrical wires pose significant risks, such as electrical shocks, fires, short circuits, and potential damage to your home’s electrical system. By properly insulating and protecting the wires, you can minimize the potential for accidents, prevent electrical fires, and ensure your electrical system stays intact. 

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

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.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.
