Our timber sash window renovation and repair service focuses firstly on window renovation and secondly on upgrading the performance of sash windows.
Existing wooden sash windows are treated to remove any rot and improve any operational issues.
The sash windows are then upgraded using our Perimeter Sealing System, which eliminates draughts and rattles.
In addition to sash windows we also work on casement windows and other timber windows and doors. Such diversification and decades of experience have made us unmatched at what we do.
For more than 30 years we have been working with listed buildings and properties within conservation areas, restoring sash windows, casement windows and doors .
Our projects range from small domestic houses to large commercial projects. However diverse the scale of our activities may be, Ventrolla’s principles never change - restoring your sash windows back to their original condition.
