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.

What our customers are saying

Thank you very much for an excellent job, by some of the nicest, most professional builders I have had working here for three decades.

Mrs Schecter, Kensington

Excellent service from the fitters. Extremely impressed with their tools and equipment to carry out the works. Certainly knew what they were doing. A welcome change

Mr & Mrs Kukk, Whitby

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.

Mary Sherwood

Hi Jarrod I refer to our recent telephone conversation and as agreed, attach hereto formal confirmation of my satisfaction with the works undertaken by your company.
