Adding Breakaway panels that allow water to flow through could be another way.  

We've got to do some interior renovations to accommodate for the loss of the garage (moving the laundry, hot water heater, electrical panel indoors and building in some storage inside), and they came in at a very reasonable price.Glad to be of help.

List of upgrades includes but not limited to:New natural gas heating system complete with new panel heaters and thermostats throughout the building. ($25k)New domestic plumbing throughout ($4k)Wiring upgrades including new meters and service entrance to accommodate new W/D hook-ups in all units ($15k)Installed 2nd driveway, 20' x 37' ($3500)24 new windows ($7200)Gutted and replaced kitchens and baths in 3 out of the 4 units.Refinished all hardwood floors, painted all units, fixed repaired trim, and all interior and exterior cosmetics.4 new sets of appliancesBEFORE                                                                                                               AFTER

They got an appraisal (think 1950s house never been updated, rear garage corner rotted apart, roof was 40+ years old and crumbled off in the wind, soffits and some wall rot, original boiler, outdated panel... a mess).

Read up on outdated and recalled electrical panel identification, some of the old panels are uninsurable.

He thinks it may have somehow gotten into a utility chaser (about 12"x12" hole behind the tub in the bathroom that, last we knew, was covered with a panel) and disappeared into the walls.

This time they mis-cut my refrigerator panels which caused an over month long delay in finishing my kitchen.  

There should be an electrical panel nearby inside the house.

check electrical panel and see if you have fuses or is it upgradedDepending on age of property: Galavanized pipes?

I'm worried it may be a negative for most buyers.Basement:I'm fixing missing panels and holes in the wall, that part is easy for me.
