On New Years day we took a little drive to Home Depot to look at some insulation. I had done some research online and was prepared to get everything from Lowe's, but as luck would have it, we stopped into the Depot first.
By the way, the impact of the insulation on the garage overall was immediate. I could feel the temperature difference as well as the sound difference right away.
Next - attic insulation, the closet door, and sheet rock!
Speaking of sheet rock. We have sold a few items on a local garage sale group on FB. A nice guy came out and bought our old grill and his buddy, a painter came by with a truck to haul it away. As we were talking the painter gave us the name of a local guy who does sheet rock work. I'm pretty comfortable that we can do the installation of the sheet rock ourselves, but I absolutely hate taping and floating, so I'm going to get an estimate to have a pro do it for us. I promise you, no amount of watching YouTube videos can overcome experience. A crappy tape & float will be noticeable on the walls forever, so to me, it is worth paying for a good job. But, we aren't there yet.
