"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.

"Construction in today’s world, where finding a reliable contractor or roofer can be a challenge, has truly astounded me. I reached out to about five different roofers for quotes, but it was AV who stood out. His first step was to inspect the attic before even looking at the roof, which was incredibly impressive. While others simply provided quotes based on their assumptions, AV took the time to ensure every detail was addressed. He even noticed something as minor as the bathroom vent not being connected, explaining how it could impact the new roof. His attention to detail, quality of service, and fair pricing are truly commendable in an industry where such standards are rare. Thank you so much for exceeding our expectations!"

Insulation questions, answered by experts

The best type of insulation for your home will largely depend on your climate and the space in your home you are trying to insulate. Fiberglass, for instance, is excellent for cold climates as it has a high R-value and won’t settle much over time; spray foam works well for humid environments as it has excellent moisture-resistant properties.

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem. 

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that’s part of your living space. Fiberglass insulation is dangerous, and the installation process is hazardous. It is also harmful to the environment. When there are so many newer, healthier non-fiberglass alternatives in the market, the lower cost of fiberglass insulation simply doesn’t justify the harm and danger it poses.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.
