And Fast Window Glazing Tips?

I have a lot of windows that the glazing has fallen out of. I know you can buy glazing compound or window caulk for repair. I want to know if there are any tips or quick fixes to accomplish this? All the windows of the house need attention and I am hoping to find a fast way to get it done.

if these are wood windows with the old style glazing, the quickest way is to hire some one to do it for you :D, seriously though you will find that it really can be done rather quickly and don't be discouraged after doing the first window or two. as you go along your speed will pick up with each window and by the time you are done you will feel like a pro. just make sure that you press it in good as you run your knife over it.

There are glazing knive available. They are like a 1" putty knife with a bend in the blade. After you get all the old glazing out and clean and prime the surface you can work the glazing into a large bead a bit longer than the pane you are glazing. Then press it into the window and work it in with the glazing knife. The knife helps you get a good looking angle on the glazing. Some people add a substance called "whiting",available at paint stores. The best tip I can give is that you should really do a good job on your prep. Glazing is really a pain in the neck and you don't want to redo it for a long time.

Do it right!

I would suggest hiring a handy man to do your windows if you don't want to. But, whatever you choose to do, you should worry about doing it right rather than doing it quickly. Because, if you do it quickly, windows still in the sashes, and without getting rid of all the old glazing, then it will look shabby, and will not last. However, if you do it correctly, you likely won't have to do it again anytime soon. And I'm talking 20, 30, maybe even 50 years!

So, what are the steps?

1. Remove window from sash.
2. Dig out all old glazing. It will likely be dried and cracking (any that's left, and I'm sure some is still left, always is). Couple tricks here. First, sometimes you can soften old glazing compound with boiled linseed oil if there isn't paint over it (which there should be) or if there are only small areas of glazing left. You can also soften it using a heat gun, but be careful as the heat can break the windows. If you choose to use the heat gun, cover the glass with think aluminum foil and keep the heat gun pointed at the glazing only.
3. Dig out the old glazing points (old ones usually are diamon shaped)
4. Carefully remove glass
5. Clean rabit where glass is inserted, getting down to the original wood. Spend some time here and make sure it is cleaned out well.
6. Use boiled linseed oil and coat the wood where the window is inserted and let it set for 24 hours. This keeps the glazing compound from drying out by preventing the wood from sucking out the oils in the glazing compound. You could instead paint the wood with a primer and then skip the boiled linseed oil, but truthfully I find the old fashioned method works better.
7. Put small amount of glazing compound around the rabit. Once you put the window back in, there should be between 1/32" and 1/16" of glazing between window and wood.
8. Put in new glazing points to hold glass in.
9. Now add glazing all around window and use putty knife to smooth it and make a nice bevel all around.
10. Let glazing compound skim over (dry) for the time recommended on the glazing compound. The ones I work with usually need 7-10 days in normal humidity and temps to skim over.
11. IMPORTANT! Paint glazing with a good primer, let dry, and then follow up with 2 coats of topcoat. I usually take this opportunity to refinish the outside of the window, so I prime the window and glazing, then repaint. And make sure you paint the glazing and onto the glass. What this does is it keeps the glazing from drying out, which causes the failure in the first place.
12. Use a good razor to clean the paint off of the glass, but don't clean the paint all the way to the putty. Leave about 1/16" strip of paint on the glass next to the glazing all the way around. This will keep air from drying the glazing and will keep water out as well.
13. Put the windows back in.

This seems very involved and it IS very involved. I usually try to do 4 windows at a time and I have each window out for about 2 weeks. But the results are great, and after that, if you maintain them (keep them painted and keep them clean), you likely will never need to do it again. Take the summer to do it and enjoy.

Also, this is a good time to make repairs to the windows. If the glazing is in as bad of shape as you indicate, there is probably a little rot, and possibly lose mortises that need to be taken care of.

Good luck.

mgrubb cover very well the way I learned to do glazing, and if you do it right you should only have to do it once.

I'm in the process of rehabbing all my wood double-hung sashes, and my sashes don't come out. I question the value of removing all the glass - the glazing on the interior side of the glass doesn't take nearly the abuse the outside surface does.

Buy a glazing tool - a putty knife on one end, angled at the other end to shape glazing at proper angle.

Practice some - you may have to do your initial line several times until you get the hang of it - it's a little easier than caulking a bathtub, but not alot!

Be careful of the glass - I've broken several panes by being too diligent about getting every last bit of old glazing and debris out of the track. Going to the hardware store for new glass takes a chunk out of your work time... Also, if you do have to replace a pane, measure all four sides. Not all windows are square, at least the old ones we're rehabbing!

Good luck - finishing your first window is cause for great satisfaction, and possibly a party...

Re: And Fast Window Glazing Tips?

You can skip almost all of these steps by refusing to use the typical glazing that comes in the can. I gave that stuff up years ago. It is difficult to apply, it takes too long to apply and it takes too long to dry in order to paint it. I use the glazing compound that comes in a typical caulk tube. After you clean out the old glazing well, no need to prime. You can glaze your sash in 90% less time then typical glazing and quickly smooth it out with a glazing knife dipped in a bucket of soapy water. It drys in one day so you can paint it - not 10 to 14 days like typical glazing from a can. It also holds up well. I am now at 340 sashes and counting down to my 420th when I will be done.

Don't "skip steps". Doing my reglazing too & I found the Sarco type "M" putty to be the best!

You DO want putty under the glass. I have an old butter knife & take some glaze, knead it a little like dough & just slice off little bits & wipe it in the track, and again & so on...til the entire rabbet bed has a nice (not too) thin layer of putty.

Place your clean glass in the bed & this is my little trick... take a soft cloth & a palm sander. Lay the sander on the cloth & turn it on & run it around the edges a couple times. DO NOT PRESS! The weight & vibration of the sander will seat the glass in the bed of putty. Quicker & safe than trying to press it in.

The only other thing I'd add to Chris27 & mgrubb is the spots where your points were might likely be under the glass a bit. I never try to find the exact holes. I take my ginsu steak knife :D and carefully push it into the place I want my points. Get a curved needle nosed plier & you can push it into place.

You're gonna love how they look when you're done!

I went from this:

To this, on my first try. So can you. Patience is your friend.
