Description of Work: Last year, I had all new dual-pane windows & glass doors installed on my house. However, I still was getting PG&E bills that were higher than had expected. It made me think there was probably an attic insulation problem. I knew of no HVAC folks, nor did the people I asked at work. Luckily, Angie's List had a "Big Deal" posted for Superior Insulation. It was a good price, so I signed up for it. | |I had also checked into the business on the internet. Home Advisor website also had good comments about Superior Insulation. | |Aaron (owner) contacted me via e-mail and, (at my request), by cell phone. wee arranged a date/time to meet for the Big Deal inspection. He came to my house and did the inspection which included a couple photos of the pre-installation attic. | |He let me know our house had only approx. 2.5 inches of cellulose installation w/some old pink insulation. We were about a FOOT short of what we needed! We had an R8 rating and should have had an R38; he goes by the PG&E standards which he said are the toughest. (We should have had an attic inspection prior to buying the house.) | |We set up an appointment for the following Saturday morning for 8:00 a.m. for attic insulation install. Aaron and his helper, Peter, arrived around 7:45 a.m. to begin setting up the truck & pre-install items. They invited me to ask questions any time throughout, and after, the process. They told me it would take approx. (2) hours for the install of about 1,800 square feet of blow-in insulation; that it would be around 14" thick by the end of the install. | |They put blue tarps on the house flooring as a protective measure and they had some soft orange cones where they'd cut off part of one side. They placed them against the corners of the wall (the corners that jut out). The cones were another protective measure to prevent any marking of the walls or wall paint (think electrical cords & insulation hoses). Aaron suited up and worked the attic side of things while Peter manned the truck and the filling of the blow-machine (don't know the correct term). | |During the install, I saw the "bales" of insulation with the manufacturer's label. It was exactly what Aaron had told me they would install ("JM Climate Pro" - blow-in fiberglass insulation). It doesn't settle or get flat; it's fire-resistant, acoustic, formaldehyde-free, and it supposed to last for 100 years. They installed 16 bags; what I call "bales". (In case you're wondering as I had, JM stands for Johns Manville.) | |Aaron put batting near the air vents to prevent clogging (from the blow-in insulation). He also put open-cell foam (gasket) near the entry-point up into our attic to prevent any "hopping" of the entry-lid whenever one turns on the HVAC system. He put about a foot of batted insulation on the attic-side of the entry lid. | |Also, he installed extra insulation over the bedrooms (most of ours are on the NW & SW side of the house; the hottest areas of our house). | |I'd told Aaron about an odd noise when the HVAC was on; an annoying squealing. He let me know it was probably a "whirlwind" vent. During the insulation install, Aaron saw one of the whirlwinds was off-kilter, so he tightened it up. Now I don't hear that racket anymore. | |Aaron also checked the ventilation system to verify it was functioning properly and made sure it was clean. I had been concerned especially about the dryer vent as it is an old house with a peculiarly slim laundry vent which does not blow out of a side-wall from the laundry room to the exterior of the house. Rather, it blows up & out the a vent in the roof. | |Aaron also placed a type of pre-fabricated, soft, almost "rubbery", cushioned outlet insulation on the inside of all the wall outlets where the inside-wall-outlets were facing the exterior of the house. He informed me one loses 11% of energy from any such un-insulated outlets. | |Peter cleaned up after the project. He rolled the tarps inward to prevent any debris falling onto the carpet. He vacuumed the flooring after the tarps were removed. Peter used one of those garden-type blowers to blow any bits of insulation from the outside areas into a pile and cleaned that up. They let me take a look into the back of the truck to see what the equipment looks like. | |At the end of the install, Aaron gave me a receipt from Superior Insulation along with a "JM Climate Pro Fiber Glass Blowing Wool" Certificate showing the R-Value, thickness, coverage area & numbers of bags used. | |Aaron and Peter were punctual, polite, patient with their explanations & honest. If I ever have a problem with this insulation, (which I don't expect), I know I can count on Superior Insulation. The job took just around (2) hours as they'd initially said. I paid with a check and didn't think to ask what other, if any, forms of payment the business might accept. | |Aaron took photos with markers throughout the installation process. That evening, he sent me somewhere around (30) pictures. (I'd only expected a couple of shots.) | |I highly recommend this company. | |
