"This could not have gone any smoother. Despite having to re-schedule the original, 1st quoting appointment, Darren was here the very next day. I had a quote by the end of that 2nd day/appointment, was scheduled the next day for the following Monday and the 2-person team was in and out within 90 minutes. My kids didn't even wake up(granted, they could sleep thru the emergency siren!) but wow. My attic/crawl space is now fully insulated! All this while we are adjusting to our new normal of social distancing and heightened sanitary measures. I would use AFI again and would recommend them based on this experience."

"Prevailing came in to insulate my basement and attic. The workers were professional and worked the entire time they were here (which seems like a low standard, but I've had situations where 4 people come to work and 2 stand around talking for most of it from other companies). More importantly, they explained what they were doing as they did it, and cleaned up after themselves before they left! Scheduling the service was quick and easy since they were able to use our Alliant Energy quote to avoid a second home assessment, and they came in under budget. Very satisfied - plan to have them back to blow insulation in the exterior walls before winter."

"Jeff Smith is based at the Waterloo office. He was very good at customer service & responded to my emails in a reasonable time given this is probably a busy time of the year (November) for them. I am having additional blow in insulation behind a knee wall & in the attic to bring me up to code. The work has not been completed yet. I am waiting for an energy audit. That is why I can only rate the company as a 3."

"The team was on time and very friendly. They explained what they were going to do and got right to work. They laid out materials to cover our belongings in the bedroom as well as the carpet. After they had installed the insulation they patched the holes really well. I won't have to do any extra work! They even vacuumed after they were done which was really appreciated and a sign they care about the quality of the work they complete. I will hire them again in the future to complete more insulation of our attached garage. I would also recommend them to friends and family!"

"A+ Comfort Insulation LLC were quick to respond, provide an estimate and complete the job requested. They did Blow-in insulation, and we are very happy with the results."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"CGM Insulation did great job installing insulation for me. Juan has lots of experience and knowledge. He knew exactly where to install to get the most efficiency. He really knows what he is doing."

"Had a water leaking through my roof from Ice dams and damage on whole wall on the west side of my living room.  They had to replace all dry wall, insulation and match the half of my ceiling to the other half that was not damaged.  Also replace a huge 1960 window with 3 new energy  windows.   Great work you would never know that the half of the room had been redone match all the paint and knock down on the ceiling to a tee.  Very knowledgeable, professional and kept me updated on all the process that was going on."
