"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."

"I have only glowing things to say about our experience using Home Genius Exteriors. From the thorough initial estimate and comprehensive inspection of the worksite and what the job would entail to the final bit of blown-in insulation, our multi-team project was completed to our satisfaction in a timely and professional manner. In the course of four days, we had a new roof, new trim, new gutters, and new insulation. Each part of the project required a different team. Each crew finished their task within the projected timeframe. Home Genius coordinated everything, including ordering and delivering the materials and arranging for the delivery and removal of the dumpster. Thanks to our Project Coordinator Ivan, every step in the process went smoothly. He arranged for workers to be at our home on consecutive days: we did not have any time in between steps waiting for availability of the next team. Ivan kept us informed of progress at every step of the way."

"I highly recommend this company for any type of insulation work. The salesman gave a very thorough presentation on all the available options for me, along with a rough estimate at the end of the meeting. I went with the option of removing & installing new rolled insulation (R30). The crew arrived on the scheduled installation date and got right to work. Sealed off everything properly, removed the old insulation, cleaned & cleared out the space, and then installed the new insulation. It was all completed in about 4 hours. I was very impressed."

Insulation FAQs, answered by experts

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Garden blankets and frost cloths are the best things to use to protect trees and plants from frost. They are made from polypropylene fabric, which is lightweight, breathable, and dries fast. If you can’t get garden blankets or frost cloths before the freeze, you should use lightweight blankets, sheets, or towels.

Yes, spray foam insulation can be applied to your ductwork and effectively insulate your ducts. Blanket insulation is the easiest insulation product to DIY since it is easy to wrap around ducts. However, spray foam insulation can also benefit your HVAC system if applied to air ducts.

Opting for insulated ducts can lead to significant long-term savings on your energy bills and contribute to a more efficient HVAC system. The precise amount you can save depends on various factors, including your climate, usage patterns, and the insulation's quality. However, on average, insulated ducts can result in savings of up to 20% on your annual heating and cooling costs, according to ENERGY STAR®.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.
