Traditional
wooden box sash windows
Traditional, wooden box
sash windows that are double glazed with a full set of weather seals and a high quality outdoor paint system offer all the
same environmental benefits as replacement upvc windows and are just as durable.
There are many companies
that offer sash window restoration services. When getting and comparing quotes, you should pay attention to the detail. A
rapid, cheap service that adds some weather seals and re-balances windows is not, in my own opinion, a window restoration,
rather a short-term fix that can be a false economy.
In my opinion, the two
things that really provide longevity in box sash windows are hardwood construction and a high-end paint system. These, combined
with a full system of weather seals, double glazed units and proper re-balancing, will produce a draft-free window that retains
heat and lasts for many years.
Restoration
My own sash window restoration work always includes:
- Sash, box and sill being stripped back to wood (as this is the only way to identify the state
of the timber and construction)
- Filling where appropriate using a high quality, two part, resin-based filler
- Replacement parts where necessary and checking and fixing of all joints
- A highly resilient, four-coat exterior paint system
- A complete system of weather seals which are incorporated at the top, bottom, sides and meeting
rails of the window
- Replacement sash cords, pulley wheels and re-balancing
Replacement
In addition, where I replace a sash, box or sill, my work always includes:
- Hardwood construction using European oak and traditional joinery methods
- Replication of all existing window detail
Double
glazing
I can double glaze existing sash windows as well as newly constructed ones. This is done using:
