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.



Fusing traditional skills with modern technology, 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 manufactured products and renovation works that exceed our customers’ expectations. Depending on the project, our installation team will be on site between weeks 10 to 16.



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 windows

Contemporary aluminium windows are much more efficient than old steel and aluminium windows thanks to the inclusion of innovative thermal break technology. Warp, fade, and rust resistant, tough aluminium window frames make ideal replacements in buildings located in harsh British coastal areas too. Combined with efficient double glazing, secondary glazing, or single 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 your or your client which includes energy improvement certificates for absolute peace of mind.

What is the best way to clean aluminium frames?

Once your aluminium windows 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, aluminium is one of the most low-maintenance window 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 windows looking their best for longer.

We were most impressed with the speed of your reply, the sympathy you had with the building’s integrity, the quality of your demo kit and the attention to detail in your quote. You are an excellent advocate for your company.
