Our Process



The Ventrolla journey begins with a discussion with a member of our team and/or a detailed home or site design survey, to explore your ideas & devise a bespoke plan of action.



Once our team have finalised the plans, we will provide a comprehensive estimate for your works. Enquiry to estimate typically takes between 5 and 10 working days.



Ventrolla fuse traditional skills with modern technology. If you require new joinery, creating your unique product begins in our UK-based manufacturing facility, and takes between 6 and 10 weeks.



The utmost care is taken to deliver quality products and renovation works that exceed our customers’ expectations. Varying from area to area, Ventrolla lead times depend on how busy we are, and the work required. On average, our installation team will be on site between 6 to 18 weeks from the date your order is placed. We will advise guide installation dates when you place your order.



Our customers come back time and time again – when they move or if they’ve phased their works – all thanks to our exceptional customer service and after care. In the unlikely event that your Ventrolla products require expert attention, we’re always on hand.



Renowned for delivering outstanding quality, all our work comes with a minimum 5-year guarantee (subject to terms), for absolute peace of mind.

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
