Renovate and upgrade the performance of the sash windows.
Treat the existing wooden sash window to remove any rot and improve any operational issues and then upgrade using modern materials to eliminate draughts and rattles. Basically make as new.
To note that the flat is on the first floor of a terraced house.
in total there are 4 windows that need to be repaired. See details below: Width x Height
132cm x 185cm x 2 windows
152cm x 109cm x 1 window
118cm x 182cm x 1 window
