Customers say: Quick response

"Jeff Alligood is a very personable and laid back guy and came out to estimate the job the day after I called the company. He spent considerable time in the attic, basement, outside the house and was enthusiastic about answering questions and offering options. He sent an estimate the next day. After doing some research about insulation and venting I called Jeff and asked if he could take another look at the house. He was happy to do so, answered some  new questions and sent a revised estimate. Jeff and his team arrived right on time the day of the job and went right to work. There was a problem with the vents I had ordered and Jeff went off to the local Home Depot, purchased new vents (which turned out to be a much better option for this job) and installed them in good time. Meanwhile, his crew sealed openings in the attic floor, installed baffles, blew in fiberglass insulation to an R55 level and capped the attic access cover. The crew cleaned everything up and they were done by mid-afternoon. All in all a nice company to deal 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."

"RetroFoam of Michigan deserves more than five stars. The representative who gave me an estimate was prompt and professional. The office staff who called to tell me installers were ahead of schedule was kind and courteous as I answered during a busy day at work. The crew who came to insulate my garage was extraordinary. They made sure my garage was left clean. They even mopped the garage floor before they left! The crew leader explained the process of insulating with foam and exactly how the holes in my walls would be patched before the team left. I am an educator of 30 years and a licensed builder. I've remodeled and flipped homes and have rental units. I'm used to swinging a hammer alongside others. This company is made up of hard-working people who charge a fair price and do exceptional work. I have advice for those that run the company - take care of your installation crews! They are exceptional! If you've read this far and are interested in having your house/garage insulated give them a call now. You will be happy you did. Now...I'm looking forward to enjoying a warm man-cave garage on cold nights!"

"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."

"Great experience from start to finish! The team was professional, friendly, and did an excellent job replacing our old blown-in insulation. They were thorough, clean, and made the whole process easy. We’re already noticing a difference in the house. Highly recommend!"

Insulation questions, answered by experts

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

Yes, guiding choices between open-cell and closed-cell foams based on needs.

Cellular shades, also known as honeycomb shades, are the most energy-efficient and insulating window treatments. Their honeycomb structure is made of soft fabric that forms layered cell pockets. These pockets trap air, creating a thermal barrier that reduces heat loss in the winter and blocks heat gain in the summer. For even greater insulation, consider double- or triple-cell varieties. Side-tracked cellular shades, which seal the edges of the window frame, can further minimize air leaks and maximize energy efficiency.

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.
