I'm doing a lot of overdue/deferred maintenance on an older 'modern' home - built in 1942 - which has a lot of interesting "modern" features (for example, plastic bathroom tiles). Right now I'm focused on the windows which are nice wood-framed double-hung manufactured (I think) units. By "manufactured" they appear to be factory hung rather than site-cut jambs and stops into which sashes are placed.
They are, by and large, in OK condition - but need a fair amount of glass replaced and lots of painting and glazing. Even then, they will be only single pane glass. I'm tempted to simply purchase replacement sash kits with thermally insulated glass. Right now, however, I'm trying to figure out how to remove the sashes non-destructively. I've taken apart double-hung sash windows before - just remove the stops!
The stops appear to be solid pieces, that I may have to remove the entire casing to pull off. I really don't want to have to remove entire window units.
I feel like I've seen window sashes like this at flea markets, yard sales, etc. (so people do seem to remove them intact). The real identifying characteristics are:
- the levers which operate the friction "counter weights" in the jambs (these do not have cords, weights or vertical springs). To operate the sashes, you put your fingers in the cutouts on the bottom of the sash, depress the levers with your thumb - this releases the pressure used to maintain a friction stop in the jambs - and the sash can be raised and lowered.
- the different jamb depths - the jambs on the left hand side (as viewed from "inside" the window) are deeper than the jambs on the left hand side. The stop on the left hand side appears to be a separate strip of wood, while the right hand side stop appears to be cut/shaped from the same piece of wood as the jamb itself - it's all one milled piece. I've taken a couple of close up shots from the bottom of the window that try to show this.
I'm starting to feel that there is either some (much easier) trick for removing these - from the front or something - or that I might as well cut them out.
My goal is to be able to strip the old lead paint from the sashes outdoors, remove the mullions, use a router to cut deeper glass beds and install thermal double-pane glass. The only point of this is to maintain originality a little. I don't want to removing the casings and I'd like to remove as little trim, inside or out, as possible. I have had replacement sashes before and really liked them (noise, insulation), but if these old ones are "real keepers" then I can work with them (add sealing bead gasket to the stiles, top, bottom and meeting rails, and thermal glass.
I'd love any ideas or input! I need to do at least 20 windows this summer, so I've got to get cracking!!! Pictures below:
