I meant where the wires used to come in. The electrician installed a new meter years ago. The box where the old one was now has birds nesting in it, which is nice. When you get new plumbing, a new garden hose faucet, or even new telephone wires, you should check to be sure the wires and pipes are sealed with plastic goo. Then check the old holes as well. Also check for cracked or missing grout. - Jed
