21st Century Machining Meets Traditionally Handcrafted Sightlines

Designed to eliminate draughts, rattles and dust ingress, the Ventrolla Perimeter Sealing System was awarded the prestigious Design Council Award (Engineering Components) in 1986. Using strips of low-friction Weatherfin polypropylene pile to seal the gaps, this patented system, along with our innovative sash removal system, are still core heritage renovation products 35 years on.

With workshops based in Harrogate, Henley-on-Thames, and Lockerbie, manufacturing our products in-house gives all parties involved complete control of the process from start to finish – from customisation to pricing and everything in between.

What our customers are saying

Ventrolla were able to beat all the other quotations that I received and answered queries quickly and informatively, making changes as required promptly and without fuss. I was kept informed throughout of lead times and manufacturing times. The real stars of the show were Rob and James who worked tirlessly and brilliantly as a team to repair sash boxes where required and install our new sashes. Thank you!

Stephen

Everybody I dealt with has been super friendly, informative, and helpful. I received emails with updates on what was happening, etc. It has been a great experience from start to finish.

I used Ventrolla to renovate my sash windows over to years ago. When two of them finally collapsed, including a bay window the size of three full sized Georgian windows they were my first contact. The office staff, surveyors and the three fitters that did an amazing job installing them in less than two days were all excellent. The quality of workmanship and the standard of installation were first class, and the new windows look amazing. I will definitely be using them again as more of my windows will need replacing over the next few years.

Alastair

This is the second property Ventrolla have restored my windows for me, and the this job was every bit as good as the first. 14 sash windows in a Grade II listed building installed/refurbed without a hitch in week. The team of 4 installers were lovely chaps, super efficient and tidy. All round another fabulous job done – thank you the Ventrolla Team
