"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."

"In the attic, we had wooden slats that covered the floor so they had to go under the floorboards. Although we were told by the salesman that there would always be a person on the other side of the wall to check for problems, the second guy was not watching and they blew a hole in the ceiling of the bedroom ( see pictures). They assured us that they would fix the hole, spackle it and repaint the ceiling. They did spackle the hole but only painted the area that they fixed - not the whole ceiling. And they did a lousy spackling job. We had to get someone else to smooth out the spackle and repaint the ceiling. We could have pushed to get them to fix the ceiling but it was late on the last day and we wanted the job done. As for the gel on the outside, the truck broke down due to the heat of the day and it took 3 days to finish the rest of the job including fixing the ceiling and the inside walls. Although the salesperson, did a first investigation of the house and said it could all be done from the outside, the workers found that one bedroom was covered in concrete so they had to drill from the inside of one of the bedrooms leaving many holes to be spackled. This time it was not so bad and we were able to sand and repaint that bedroom. But the workers could have done a better job of cleanup of the sparkle. It was all over the baseboard and the rug and we had to use rags to clean it up. We realize that things happen. And maybe we were too hopeful based on the salesman's pitch. But we would rather have had the salesperson tell us the truth about the possibility of drilling holes in the inside of the house even though he did a thorough inspection. All in all, we are hoping that insulating our house will save us a lot of money in heating costs. The manager was very accommodating, we saved some money by paying with a check vs a credit card. The workers were very nice and the lead person was very knowledgeable. Any renovation is stressful. We would probably recommend them because now we know what to expect. This company was recommended to us by a number of people. We have no doubt that the product itself is excellent. For that reason, we expected it all to go smoothly. It did not. Everything that could go wrong, basically did. It all got fixed but ... We did not plan for a hole in the ceiling, the truck breaking down and go into the shop to fix the problem with the gel overheating and not coming out of the hose fast enough, the concrete in one of the bedrooms that meant that all the holes had to be drilled on the inside of the bedroom and we had to repaint. So for those reasons, we are giving them a rating of fair. We hope your experience will be a lot better than ours !!"

Same quality and company, NEW NAME!!!! Yep we've upgraded our branding to better reflect out company goals. As always, quality products are essential for success, but without certified and trained technicians installing everything to the exact specifications for greatest success, your home wouldn't get the best results. That's why we do things right - every time. Our excellent products come with extended/lifetime warranties INCLUDED - there will never be an upcharge for a warranty. The adage "you get what you pay for" is 100% true for Insulation Geniuses. We'd rather explain the investment up front rather than trying to explain quality for the next 20 years...

"Due to below freezing temperatures this winter, I had a pipe in my garage burst (the pipe was garage facing, not behind the walls). While I was thankfully home when this occurred and shutoff the water within 10-15 minutes, portions of my drywall got soaked, leading to cosmetic damage. However, I wasn't sure if a longer term consequence of major structural damage or mold would occur. After inspecting the drywall, Larry saw no indication of mold or major structural damage (3 months after the incident), and gave me a few suggestions on how to fix the cosmetic damage by making a quick Home Depot run. Larry could easily have quoted me to gut and replace an entire wall's worth of drywall, but instead, walked me through a fairly inexpensive DIY fix and told me to give him a ring back if anything changed over the summer. I would absolutely recommend Doyle Drywall."

"It's been a few years and I couldn't be happier with my new roof. We had a little bit of a hiccup during the job - it took about a day and a half and went into the evening hours, when the salesperson had assured me they would be leaving by 6 PM. But a foreman came to discuss it with us and we worked it out. All of the wood underneath had to be replaced and the crew was able to get it done. It's very beautiful and hadn't had any issues."

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"Great! The technician assured me my system was in great condition. He checked the coolant, inspected all parts and gave suggestions of how to get the air to come out a little better through our old vents. He was honest, knowledgeable and polite. Very happy with their service."

"Everything went beautifully.  Scheduled it promptly, arrived on time and took care to protect the rest of the house. The team was thorough and polite. I was impressed with the quality and look forward to the next project. Most importantly, the wife was thrilled. We never thought the rooms could be improved we were just hoping a fresh coat of paint would make them look better, but the repair work was incredible, they  like new walls again. I am now considering my next project and look forward to Joseph and the team working their magic once more. For a project i was going to complete myself, I am so happy I decided to have it done correctly and professionally. Really top notch work.

"I have a contract with them.  It took them quite a few times, but I think they finally fixed the problem that I had with my heating unit.  Everybody was polite and caring.  It took 5 or 6 visits for them to figure out what the problem was.  I think and hope so the issue is resolved.  My overall experience was very good.  The quality was okay."

Insulation questions, answered by experts

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

Insulation prevents heat transfer, which keeps your home cool in summer and warm in winter. Regulating the temperature in your home is not only more comfortable for you, but will lower your heating and cooling bills—it’s a win-win. Make sure to determine the correct amount of insulation to ensure it is enough for your home and climate.

The most insulative type of insulation for behind drywall is spray foam insulation, but this is the most expensive insulation available. The most common insulation—sometimes considered the best for the value you get for the money—is fiberglass roll or fiberglass batt insulation, which is significantly more affordable but also far less insulative. The best kind of insulation for your house will also vary based on the climate in your area, your budget, and more. A professional insulation company can help you decide which type is best for your home.

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.

The cost to install a radiant barrier ranges from $700 to $2,800, depending on the size of your roof and the type you choose. Most people pay an average of $1,700 to install a radiant barrier. Foil options, both single- and double-sided, cost between $0.10 and $0.90 per square foot, while spray-on options start at $0.60 and go all the way up to $1 per square foot—which can add up quickly.
