If you are renovating a home, building a home or just renovating a room….. before the drywall goes up…… TAKE PHOTOS of what is behind your walls! My framer told me to do this and I can’t even tell you what a lifesaver it has been! I’ve been have this musty smell come out of a few of the light switches and under the bar sink in the kitchen. By posting my question and the photo below on a DIY website, a plumber was able to help me pinpoint what was wrong without me having to tear out all the cabinets!
Now we will probably have to just cut a small hole. I’ve used these photos with electricians to find wiring and to check what the framing looked like behind a wall in order to raise a door up. It has saved a TON of headaches. Just wanted to pass the tip along!
