After getting replacement windows for my house i saved the old windows thinking if several projects for them. The major problem is several of the sashes are painted with lead paint. No Martha Stewart you cant just paint over the wood. At least not in Massachusetts. So always take safety first. Do this on a drop cloth like an old shower curtain. Ware a dust mask. Wash your clothes separately not with the kids. Keep all kids away until after the clean up. Also we will be using razor blades and have the potential for sharp glass.
Sorry about the pictures there is no flash on my phone and the glass was transparent.
Your going to need
a razor both the double pointed (like in a box or dry wall cutter) and the straight edge both with holders
flat head screw drivers
soap & water
small pliers (needle nose work goodgreen scrubby
Step 1: Select the Window
Things to look for
no cracks in glass
no silicone holding window in
Step 2: Carefully Remove the Putty
The two things that you need to look for are
- Glazer points
- small bumps of putty stuck to the wood
Cut down. Take your time make several passes don't rush don't push against the glass. Make sure their are no bumps of putty that will hold in the glass. There should be a knife thick grove between the window and the wood. Watch out for points dulling the razor.
When i have broken the pains it was because of these bumps or hidden points.
Step 3: Remove the Points
Points come is several shapes see picture.
- Triangles - These can be removed with the screwdriver one point sticks into the wood the other two are parallel against the sides. Push up or down on one of the exposed points and rotate them out. Don't push against the glass. These are easy to remove
- Small diamonds (rhombus if you are in grade school) these are the hardest to remove wiggle them out bent them up with the screw driver and grab them with the pliers. i broke the most windows on the ones the were pushed in so only the very tip shows and i have missed them. Run the razor blade around the edge of the glass to find them.
- Large Y shape things with tabs that are used with the putty knife to push them in. Easy to remove.
- Also small nails
Step 4: Remove the Window
If all the putty is removed and all the points are out the the pane will just fall out. Don't push,Don't pushDon't pushDon't pushDon't pushDon't push, Go back to the edges with the knife, if stuck, the pane will loose if forced.
Step 5: Wash the Glass
After all the panes are out its time to clean them up a bit.
Lie them flat on a board that is very very flat (some of the glass might be curved be careful)
Using the straight razor scrape the extra putty off the window. Scrape along the window Don't push down!!!!!
Wash window with Hot Soapy water and green scrubby.
From there I rinsed the window in the tub with a large cup of ht water. Be careful the pain might have sharp edges should have been rounded at the glass shop. Never hold the glass by one edge an flip it, the glass cant support it weight if held like that try to hold two edges and rotate it to get both sides
