Ventrolla banishes the draughts, rattles and heat loss associated with sash windows in the past. With over 30 years' experience, Ventrolla are the Sash window repair, draught proofing and double glazed sash window experts. 

Ventrolla has addressed the old disadvantages of traditional sash and casement windows that meant compromising on comfort and the cost of heating.

Today we help customers preserve the features, not only to preserve a building’s aesthetic appeal, but also to add to a property’s value and saleability.

Over 25 years we have established a national network of skilled craftsmen.  Through them we can offer our customers a unique and guaranteed sash and casement window renovation service that can avoid the need for unnecessary and costly replacement.

We have renovated sash windows in hugely diverse buildings from one end of the country to the other.  Ventrolla were brought in as part of a prestigious project to renovate and upgrade the sash windows of the French Embassy and the Institut Francais in London.

At the other end of the scale we were approached to renovate seven timber sliding sash windows at a Grade II listed Georgian farmhouse in the Welsh village of Molleston.
