"We got a couple of estimates to spray the cellar sills where the house meets the foundation. We chose Foamcoinc because of the knowledge of the person that came and gave us an estimate...I think his name was Dave. He had some good ideas on how to spray and seal under the bay windows, left samples of the foam with us, and some more information. I thought that was great so I could make a more informed decision. Not to mention the 'R' value of the foam he would use was much higher than the other company's and he price matched the other company's price in his estimate! They showed up about a half hour early, which was slightly inconvenient. Thank goodness my husband was home since I just got out of the shower when the doorbell rang. They came in and went right to work. They did everything they said they were going to do and a bit more than expected. The thickness of the spray insulation was thicker than they specified and they were neat and clean! A great experience! Try them out for yourself! I will be calling them for when I am ready to do the attic."

"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."

"We hired Mark and his team to install new spray foam insulation in our attic to meet the higher demands and code compliance required that you can not get with old style bat insulation. The spray foam sealed all of the leaks we had and made our home less drafty. They also put in new solar attic fans to keep the heat down so our HVAC did not have to work so hard. Great Job Koala!"

"The job was very well done. Gustavo and his crew were EXCELLENT. Dealing with the project Manager Taylor was EXCELLENT. One of a kind company. A unique feature that was used for installation was the inclusion of BOTH Sanford insulation and housewrap. I have not had another contractor offer me both of those. It’s always either one or the other. Home Genius is backed by the better business bureau and is a James Hardie certified installer for those looking for one."

"I purchased a multifamily house with 2 stories. The 2nd floor had 1 inch original hardwood from 1920 that laid on the floor joists so you could hear every footstep downstairs and my tenants almost moved out. I hired Cesar to take on a tedious and technical ceiling soundproofing technique for the apartment using RSCI rubber clips, hat channels, insulation, and making the 1st floor airtight. I was so impressed with how he was able to juggle handling my tenant for 2 weeks, compensating for delayed shipping by driving 3 hours to New York and picking up the materials himself to make sure we meet the deadline, redoing 1 entire room at his loss and not charging me for it because the original technique we tried did not work, and listening and working with me to make sure we didn't miss any details that would cause sound transfer (and this was impressive because I am very detail oriented). My tenants moved in and were very impressed by the finished looked of the new ceilings and crown molding. We saw a sound improvement of about 15 STC in both airborne and impact noise. It cut down sound transfer by 2/3 in the 1st floor apartment. I will be adding rubber underlayment upstairs underneath the new flooring to completely block out the rest of the impact noise that transfers from the floor above to the walls downstairs that support it! I'll be calling Cesar and his crew again."

Insulation questions, answered by experts

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.
