A selection of completed sash window restoration projects in the South East of England

Sandhurst Royal Military Academy

After the existing windows, dating back to 1862, were given their marching orders due to their poor condition, the timber renovation specialists were drafted in to upgrade the ageing sashes.

As part of a £7.5 million refurbishment across two years, the Grade II listed building, used by the Army Medical Directorate, presented 450 sash windows in dire need of  complete renovation and upgrade due to many years of exposure to the elements.

Coleherne Court

Window specialist, Ventrolla, has recently commenced work on the historic Coleherne Court in earls court, south west London, which was once home to Diana, Princess of Wales.

Ventrolla was appointed the project by Coleherne Court Maintenance Fund following a recommendation and, to date, around 20 apartments have had their wooden sash windows and French doors restored by the company.

The 213 luxury apartments at Coleherne Court span three blocks and are set in an acre of landscaped gardens.

Brixton Homeowner

Ventrolla, the sash window renovation specialists, were called in to help when a homeowner’s original sash windows were damaged in a fire.

The front bay window was part-damaged, with two of the bay windows just needing a general overhaul, and the third needing full replacement. 

Ventrolla renovated to two remaining windows and carefully replicated them to create a new third window in keeping with the rest of the bay.
