With over 30 years' experience we offer sash window repair, casement window repair, slim double glazing, draught-proofing and full replacement windows.

By restoring your wooden sash or casement windows with Ventrolla, you can virtually eliminate draughts and rattles while working towards lowering your winter energy bills all at the same time.

Alternatively, sympathetic timber replacement double glazed sashes are also an option for period home owners. The benefit of replacing only the moving sashes with new slim double glazed alternatives means minimal disruption to the sash boxes themselves (and therefore your decoration) whilst resulting in a modern performing product and the energy benefits associated with that.

If the existing windows are beyond repair, or complete replacement is your preference, then bespoke new double glazed windows can also be manufactured and installed by the experts at Ventrolla, who can match your existing timber window profile, including the box frame, using traditional joinery methods.

Ventrolla offer a free no-obligation survey and quotation service and is a nationwide company with local craftsmen covering the whole of the UK – guaranteeing a team near you. Call free today on 0800 0277 454 or visit


Example of work

Timber Sash Window - BEFORE Renovation

Example of work

Often, windows we come across look beyond repair, however, with the right care and attention, a window looking this distressed can be brought back to life through renovation and draught-proofing, making it an attractive, more energy-efficient period window. This is a photo of a 'before' window we encountered in a project. See other images for the 'after' photo.
