"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!"

"Thermal Guardians insulation performed insulation services in an exterior crawl space below my home that was letting cold air into the house. The area was difficult to access, but they more than rose to the challenge and completed the work effectively. I will definitely use their services again."

We removed the old fiberglass insulation & blew-in our TruSoft cellulose insulation.  Also looking at this picture we can see Nate our crew leaders showing off why we use TruSoft insulation, notice the lack of dust!
AC handler and attic not properly insulated.  Attic was not air sealed and needs to be air sealed before we can insulate the attic.
Horrible insulation around this trunk.  We will replace or rewrap with mastic tape.
We see dirt in the insulation and when we pull back the fiberglass insulation we can see the attic was not air sealed.
Attic is not air sealed and has exposed fiberglass insulation.  Exposed fiberglass insulation does next to nothing to insulate.

Insulation FAQs, answered by experts

Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors. While homes in mild climates won't gain as much benefit from having an insulated basement as those in cold climates, the effects are still noticeable on your energy bill.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures.
