"There was a problem initially with the radiant barrier installation - the first crew of two were installing 30" wide rolls lengthwise along the roof end to end  instead of from ridge to eave as the manufacturer recommends and made a couple of other minor mistakes which were easily corrected. After talking to the manufacturer, the sales rep offered to take out what had been installed and re-install according to spec or continue as already done with sealing of all seams and a discount on the job. Done this way, the foil would not have the insulation properties per spec but would provide the radiant barrier I desired. I chose the letter option and the barrier work was continued by another crew on the 2nd day. On the 3rd day the crew finished up with the barrier then blew in the installation.

With the exception of the initial problem, the work was done neatly and professionally by courteous workmen who cleaned up completely after the job was done.

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...

"Bob the owner helped me through the whole process from having the audit done on my home and did the insulation work as well. His crew was also polite and hard working, they got the job done when they said they would and I’m so pleased with the results ! My home is the same temperature on every level and my energy bill is lower then it’s ever been. Thank you Bob and your team I will definitely be referring you to my friends and family."

"i scheduled an appointment to get 3 missing shingles replaced. i saw the $149 deal that included a full roof inspection, replacement of up to 5 shingles, attic inspection and a few other maintenance tasks along with a $250 credit for future use. i really only needed the shingles replaced but i'm glad i purchased this deal. Howard (one of their head techs) arrived right on time for the scheduled appointment. first thing he inspected was my attic. he found a few issues and described them fully to me along with showing me pictures. he noticed one of my air ducts was not connected, which meant i was heating and cooling my attic for who knows how long and also meant my bedroom was not getting the right air supply either. to save me time in having to hire an HVAC specialist, Howard asked me for a roll of duct tape and was able to reconnect the dislodged air duct. he then spotted a leak in the roof about the size of a quarter that was dripping through the insulation. he also saw water marks in another location but wasn't quite sure how it got there. after he inspected the attic, he hopped up on the roof. he replaced the 3 missing shingles (didn't match my current shingle color but no big deal). he also found where the leak was coming from. apparently there was a bullet casing stuck in the roof which was causing the leak! after his work was complete, he gave me a full description of what he saw and a few recommendations. he answered any questions that i had. Overall, Howard seemed like he had a lot of experience and was honest. total time of the work took about 2 hrs 15 minutes from start to finish. i would use them again in the future for any roofing needs. he told me they do other work like windows and siding. my only negative was that my appointment date was about 1 month from when i called to schedule it. i'm guessing it's because they are busy and booked up but it was obvious after the quality of service that was provided. also, the pictures he took were supposed to be sent to me. it's been about 5 days now since service and i have not received them yet."

"They pointed out areas of air loss that needed to be covered or blocked and advised  more attic insulation which service they will provide. Their price offer seems reasonable.  I'm still crunching numbers.

"I have an old house and new addition that was not insulated properly and a sun room that needed insulation. Dan was extremely knowledgeable on what needed to be done and his team did outstanding and professional work I highly recommend them! I wish I would have hired him first!"

"We have the BGE Home protection program, so we have them come out in Fall to do a check-up on the heating system, and in the Spring to check-up on the A/C. They are always prompt, pleasant and professional. In the past we have had them repair the system and we area always happy with their work. The protection plan is well worth it - we had a water heater die and it was great that we could call BGE and have the problem fixed without having to pay thousands of dollars.

"My home was very drafty.  During the consultation I was told that by insulating my heating and AC bills could be reduced by 40%.  This past winter was not cold enough to compare, but in the summer my air ran constantly and my bills were not reduced even 20%.  My interior walls have nail pops everywhere.
