How can I tell when to replace putty on my windows??

Answer 1

When pieces fall out, or the glass rattles-small cracks can be painted over.

If the putty is REAL old, it may be hard to remove-

Answer 2

If when you pick at it with a fingernail, big pieces come out, or there are obvious signs of leakage, it is time to replace it. But if you have puttied windows, it is worth considering replacing the entire window -- you want double-paned glass for insulation, and the old wooden frames may have deteriorated.

Answer 3

When you poke at the putty with a putty knife and it is hard and breaks or if the window panes rattle or seem loose. Putty eventually hardens and shrinks away from the pane.

Answer 4

when it cracks and starts to fall out. Clean with putty knife or if you are into cool tools get a MultiMaster you will finish the job before others get their tools ready. Good Luck

Answer 5

I would check it after so many months every year. If it starts cracking or peeling I would consider replacing it. If it starts leaking rain into the house replace it.

Answer 6

Just look for cracks or other voids. This will indicate the possibility for air or water to enter the home.

Answer 7

if the glass rattles,it is not sealed.tap on the sash,while tapping place a finger on each pane one at a time,if rattle stops when you touch one ,it is loose...there will be more than one loose pane per sash,recaulk and paint,
