Plumbing and Electrical Covers – Plumbing covers are frequently plumbing clean outs around the exterior of the home. These are usually concealed with a dome shaped cover. Any missing covers can allow water to penetrate and leak behind the siding and should be replaced. The electrical outlets around the exterior of the home should have newer rain covers that allow protection while the outlets are being used. Plumbing and electrical covers are important safety items and can usually be installed quickly and economically.
