Ventrolla Ltd
Ventrolla is the UK's leading specialist in heritage window restoration, sash window restoration, timber window repair and listed building window conservation. For over 40 years, we have partnered with conservation officers, architects, surveyors, contractors and heritage property owners to restore, repair and upgrade original timber windows and doors while preserving the architectural significance of historic buildings.
Our conservation-first approach prioritises repair and sympathetic retrofit over replacement wherever possible, combining traditional joinery craftsmanship with award-winning innovation to improve thermal performance, reduce draughts and noise, and extend the lifespan of original timber windows. Since 1983, Ventrolla has restored, renovated or replaced more than one million windows across the UK, from listed cottages and country houses to schools, churches, public buildings, royal residences and nationally significant heritage assets.
Our proprietary Ventrolla Perimeter Sealing System (VPSS), recipient of the Design Council Award, together with our Sash Removal System (SRS), remains at the heart of our restoration methodology, delivering improved energy efficiency and operational performance while retaining historic fabric.
Working closely with architects and contractors from the earliest project stages, we provide comprehensive condition surveys, technical advice, specification support, CAD drawings, phased project planning and specialist heritage expertise for refurbishment, conservation and retrofit projects. Through Ventrolla Consult, our dedicated planning advisory service, we also support planning applications and listed building consent, helping project teams and property owners navigate heritage approvals with confidence.
With nationwide specialist workshops, master craftsmen trained through the Ventrolla Academy and a commitment to responsible sourcing and exceptional workmanship, Ventrolla is trusted to deliver technically robust, conservation-led solutions for some of the UK's most important historic buildings.
