"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!"
