An Overview of a Wood Window Restoration
Remove existing window ( whether it is one sash or multiple sashes)
Inspect the sashes for damage and joint integrity, then secure them so they remain square as they travel to the shop
Remove all existing hardware, noting if it is original and/or if it can be restored.
Fully inspect the sill, jambs ( channels) and stops for damage and repair as is necessary
Secure the window opening from weather and intruders. If sunlight is needed in the space, plexiglass can be used rather than 3/4 inch plywood
Back at the shop, Remove the glass, noting any rough edges, cracks or damage
Strip the sashes and stops down to their original wood
All joints are treated with an antifungal solution
Repair sashes and stops as necessary
This can include replacing any wood, that can not be restored, with similar wood from your home’s ‘general’ age. ( We have reclaimed wood as far back as 1873 )
Joints that are loose or failing, are either rebuilt( see above) or restored using Abatron 2 part wood hardener and epoxy. It is also very common to strengthen the sash joints with a wood dowel or a sash pin. It is not uncommon for a sash to be clamped and squared.
Apply Linseed oil to the glass rebate, to condition it for glazing ( putty) and apply linseed oil on the top of the top sash, the bottom of the bottom sash and the sides of both sashes.
Two coats of Oil primer with light sanding between application
Reattach meeting rail weather stripping where appropriate
Re-install glass and putty to a finished state
Apply one ‘Top Coat’ preferably Acrylic or Oil
Clean and lubricate all hardware where possible
Install new ropes or chain to the sash weights.
Reattach sashes
Install sash stops and adjust for ease of operation
Clean the glass and touch up any marks from installation
