They came out and did a thorough inspection and estimate within one day of our initial call. The estimate was more than fair and we scheduled the job for a week later. The team showed up on time and ready to go on the promised date and spent the next few days crawling thru attic spaces in 104 degree weather without a complaint. After all the bats and blown in insulation was in place, the various holes in walls and ceilings patched they did a fantastic job of cleaning up. Two thumbs up. If I had more thumbs they'd get them.
