Rob, James and Tyler Window Fitting

Rob, James, and Tyler were absolutely professional and kind throughout the entire window fitting process. They paid great attention to every single detail, ensuring that everything was done to the highest standard. They also kept me well-informed at every stage of the job, explaining what they were doing and why. On top of that, their efficiency was impressive, the work was completed much faster than I expected without compromising quality. I highly recommend them to anyone looking for skilled and reliable fitters

Arched Secondary Glazing

Lucas, Jakob and Noah installed some secondary glazing into two arched sash windows in Bristol. The shape of each window was tricky for the surrounding trim, but they did a very neat, professional and tidy job. Great to deal with and the windows look excellent. Thank you.

Mark Hucks

I thorough recommend Ventrolla in Bristol

Despite wet weather Rob, Ty and James were efficient, tidy and thorough. I can't thank them enough for replacing the rotten wood of my old windows. I thoroughly recommend Ventrolla.

Mary Mortimer

Excellent and professional service

Excellent and professional service. I used Ventrolla to repair my bay window and the finish and quality was fantastic. The Installers were on time throughout my installation and consistently went the extra mile – assisting me with queries and giving me advice on elements outside of their original remit.

The A team

Wow, what can I say about Ventrolla. I researched long and hard before taking the plunge and I’m absolutely blown away by the results. We dealt with Paul in Bristol who understood what I wanted from the start. Communication was fantastic throughout. Rob, James and Tyler just finished our two week installation, their work ethic, attention to detail and end result was to the highest standard. They were are a pleasure to meet. I was reassured I had the A team and I really did. Thank you all so much.

Replacement sash windows in Georgian Farmhouse

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.

Our surveyors understand Bristol’s conservation areas inside out, and work closely with homeowners, architects and contractors to ensure every restoration meets both heritage and performance expectations.

Sash Window Restoration and Joinery from Our Bristol Workshop

Our Bristol workshop has been running since 2022, led by a team of six – three bench joiners, two finishers, and a carpentry and joinery assistant. Many of our sash window restoration and replacement sash window projects are manufactured locally in our Bristol workshop, allowing us to replicate historic detailing with exceptional accuracy.

Every window is built start to finish by the same joiner, then moved to glazing and finishing, with traditional mortise-and-tenon construction throughout.

We use premium hardwood like Accoya to ensure quality and durability, No finger-jointing. No duplex or stick-on bars. Through bars only, in line with historic practice – the way these windows were originally made, and the way they should still be made today.

About Bristol's architecture

Bristol’s windows tell the story of the city – Refined Georgian sashes in Clifton, larger Victorian panes and bay windows in Totterdown and Bedminster, metal-framed multi-pane glazing along the harbourside. Three centuries of window architecture – and yet, the issues are universal: draughts, rattles, dust ingress, sticking sashes, failed putty, and timber softened by decades of Bristol weather.

Our award-winning Perimeter Sealing System (VPSS™), bespoke joinery and like-for-like glazing deliver a window that looks untouched and performs to modern thermal and acoustic standards.
