Old wood windows and doors in poor condition can be restored and brought up to better performance.
Here are some important considerations:
- Caulking may be used to fill gaps smaller than 1/4"
- Foam backer rods and caulking may be used to fill larger gaps
- Old doors are likely solid wood and may need to be tightened up at the joinery.
- Install weather stripping around frame openings and functional parts.
