Almost all of my plumbing runs from my utility room, through the garage and up into my home. Last year we had our pipes freeze but luckily caught it in time before anything bursts. Directly above my garage is my kitchen which is always cold and the floor freezing.
So my question is can I pull down the Sheetrock and spray spray foam over the pipes? There's nothing there now.
Had a small leak so I cut open the Sheetrock to take a look and saw there was absolutely nothing there. I could see light shining down from every place a pipe went through the first floor.
