Easy access to Ventrolla products & services

It can't be denied that specification is an essential part of successful construction project design. A poorly written specification can literally make or break period renovation projects, whereas a well written specification can enhance project delivery and save your client money too.

Allowing you to clearly define your projects intent, costings, dimensions, performance, and construction, Ventrolla product specifications are available on
NBS Plus and RIBA Product Selector.

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!


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.


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
