Although there are lots of companies that offer the restoration services for box sash windows, you can actually do the process on your own, and here’s a step by step guide to help you through:
Get the Sash Out
The first thing that you need to do is to remove the sash out of the window. Simply pry-off the stops and then pull the lower sash first then slowly remove the cords as well as some of the chains on both sides until everything will eventually be taken out.
Clean the Joints
Before you start with the box sash window restoration, you have to clean the window joints entirely. Use a rotary tool to grind any of the rotten wood and all other areas that have loose and open sash joints.
Prime the Sash
Apply epoxy afterwards in order to restore the window joints. Wait for one more day until such time that the epoxy is fully cured and start to hand sand the window sash using any type of sand paper. Wipe up the dust after you are done and seal the wood with any oil-based primer.
Lay the Glass
The next step is to lay the glass part. Roll the window in a long rope in between your hands and then slowly press it towards the groove right around the window pane. Press the pane evenly towards the compound.
Re-hang the Sash
The next step on your box sash window restoration project is to re-hang the old sash. Make sure to clean the hardware well before you re-attach it. Slowly reattach the cords and the chains to the upper sash windows and then re-install the beads and replace them with new ones. Finally, hook the cords or the chain on the lower sash and then place both stops back on the jamb in order to secure the restored window sash in place.
Now that you have restored back your box sash window, the next thing that you must focus on is the type of door to pair it with. The timber doors would look good beside the sash window so consider this for your home renovation project.
