I've seen videos where people put an additional piece of plexiglass at the rear of the window opening, attach a plastic edge to the plexiglass and attach with "pivot screws" and it creates an additional air-space and is removable for cleaning. 

And I notice part of the ceiling was damaged, my husband went up to check and to our surprise, there was a bundle of cash wrapped in plastic!

Its a hard plastic/rubber type coating they put inside your existing pipes insead of replacing them.

If you are that worried about it rap yourself in plastic and stay home.

Most of the time it's cheaper to dig and replace with plastic.2.

I have also had a large number of calls or texts like do you have a covered casserole dish, tin foil, plastic saran wrap, virgin olive oil, a colander, etc.  

Who knows what happened here8-Fridge seal on double door completely gone including plastic product that holds the seal. ( guess when owner buys seconds, there is a pretty good reason why no one wanted it).9-Mold in back of one bathroom into closet walls and very active 12 inches by 3 feet.10-Glass everywhere in back yard. lots of broken windows, guess why no screens!

My dad had a tipple bypass surgery around Christmas and it was touch and go for a bit. 

So maybe I can just put some plastic between them and call it a day, but my fear is that in the future the copper could leak, which could result in thousands of dollars in damage depending on when it's finally noticed.

Those plastic covers are pretty simple to open even with a lock on them.Plus they are low voltage.Why does it have a locked cover on it?
