Their estimator Ken agreed to meet us on a weekend, even though they usually don't work weekends, so that was a plus. He arrived on time and helped us understand the different options we had to insulate our 1,500 sf home. He was very helpful and friendly. The installers came 2 weeks later and did the job within 3-4 hour hours. They covered the entire interior walkway with plastic that they carefully taped to the walls. They installers were friendly and pleasant, given the hard work it is to work for hours in a cramped attic that is only 5' at the peak. They cut and installed the batts in between the rafters and into most ceiling gaps, but there were a few places especially around the far perimeter that they didn't fully cover with the insulation. They did cut square openings in the batts to properly expose the incandescent ceiling can lights. Although I can't tell for sure, but I think there are some can lights that they didn't expose, and just covered them with insulation because I think I felt a can light under some insulation when I later crawled on my belly in the attic. (I had to go up and reattach an A/V system cable in the attic that came lose during their installation. This was no fun but partly my fault for not properly securing it during my initial installation in the attic.) My hope is that the insulation is installed away from ALL can lights so there's no risk of a can light catching fire! Maybe I should have it inspected...? After they left, I unfortunately noticed 3 can lights that are now slightly pushed down from the ceiling, as if they were stepped on or crushed. The paint and drywall surrounding the can light cracked and you can almost see the adjacent rafter pushing thru the ceiling at one of the lights. It's only noticeable when looking up, but it wasn't there before the installation. There are worse things that could have happened, and in all fairness the installers did actually fix 3 or 4 can lights that were already drooping out of the ceiling, they reattached the clips in the attic to make these lights tight to the ceiling as intended. They get points for that so I'll consider it an even wash. So far the house does seem warmer during cold nights, and cooler during the day. I feel the money is worth it, and look forward to seeing how much cooler the house is this summertime.
