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.

Energy Efficiency

High performance aluminium sliding doors

Contemporary aluminium sliders are much more efficient than old steel and aluminium doors thanks to the inclusion of innovative thermal break technology. Contrary to popular belief, modern sliding doors are just as secure and efficient as any other door, retaining optimum amounts of heat and keeping burglars out for decades to come. Warp, fade, and rust-resistant, tough aluminium sliding doors make ideal replacements in buildings located in harsh British coastal areas too. Combined with efficient double glazing or secondary glazing, you can combat rising fuel bills and improve energy efficiency across the board with a high-performance Ventrolla installation.

Once we receive your final payment, our handy ‘Care Pack’ will be sent to you or your client which includes energy improvement certificates for absolute peace of mind.

How do you clean aluminium doors?

Once your aluminium doors are installed, they need very little maintenance to prolong their lifespan. Requiring a quick wipe over with a soft cloth and a mild soapy solution every few months and carefully removing any debris from the track, aluminium is one of the most low-maintenance door materials around.

Once we receive your final payment, our ‘Care Pack’ will be sent to you or your client which includes handy Maintenance Instructions to keep new aluminium doors looking their best for longer.

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

Frequently Asked Questions

Are aluminium sliding doors thermally efficient?

Modern aluminium doors from Ventrolla feature cutting-edge thermal break technology. Designed to notably reduce heat loss and condensation, unlike old steel and aluminium doors, our robust multi-chambered aluminium frames will not contract or expand in extreme temperatures either.


Incredibly thermally efficient and strong, depending on the glazing specified, our aluminium bifold doors can achieve A+ energy ratings with non-insulated, super-insulated & Passive House compliant frames available.

I live in a listed building / conservation area / AONB - can you work on my property?

Quite simply, yes, we can! We have completed lots of work over the years on listed properties and those within conservation areas and Areas Of Outstanding Natural Beauty (AONB). Working closely with local conservation and planning officers, English Heritage, Historic England, Historic Scotland, and Cadw, you can trust in Ventrolla to reinstate and sustain unique architectural features whilst simultaneously heightening historical value too.

Do you offer an installation guarantee?

Yes, our work is guaranteed for 5 years.

Is there a minimum order value?

No there isn’t for our full renovation, draught-proofing, or bespoke new joinery service. However, we can’t usually help with smaller works than this (e.g., broken sash cords, cracked glazing, etc.) unless they form part of a larger renovation project.

How long will the work take to complete?

Varying from area to area, Ventrolla lead times depend on how busy we are, and the specific renovation work required. On average, our lead times range from 6-14 weeks from the date the order is placed. Your Surveyor will be able to advise you further on current lead times, and our operations team will be able to confirm exact timescales once you place your order.


PLEASE NOTE: In these unprecedented times, coupled with the latest COVID measures, please be aware that our lead times could be longer than originally specified. Should there be any impact on your installation date, please rest assured we will keep you updated throughout the process.
