"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."

"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."

"Atticare did a thorough evaluation of the home. Because the soffits were in disrepair, there was a pest issue. Atticare did a great job coordinating with the roofers. The old insulation was removed and the area was inspected for pests, cleaned and sanitized. They returned after the repair to make sure all was sealed, and installed the new insulation. They also helped lay down some plywood for some flooring in the space as an extra. Before doing their work, they laid down material to protect the floor and removed everything cleanly. They were efficient with their work and I was pleased with the job they did. The job was priced as quoted with no surprises. Marlon and Luis coordinated the job and were friendly, professional, and experienced."

Insulation questions, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.

Insulating a stone house is an expensive and involved process because it requires building a double-walled house. The walls don’t need to be the same thickness, but they both need to be thick enough to handle any structural demands and meet fire and safety standards. The insulation (usually foam or fiberglass) is then installed between the two stone walls.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.
