High performance commercial sash window renovations

Improving old commercial buildings is a delicate procedure that should only be tackled by seasoned specialists. We know better than most it can often be difficult to balance cost against the least intrusive way to improve the property’s appearance, especially if it’s a heritage building. So, you’ll be pleased to learn that when it comes to identifying, repairing, and replacing draughty commercial timber windows and doors, our knowledge and experience are unrivalled across the board. And in line with our customer promise, where possible, we will always suggest renovation over replacement.

With Ventrolla Commercial you can expect energy-efficient windows and doors that meet modern regulations fused with meticulous planning strategies, structured deadlines, detailed surveys, expert support with tenders, highly detailed specifications, and a real understanding of how project stakeholders work within the commercial world. Furthermore, if your commercial energy improvement measures require consent, e.g., listed buildings or properties located in conservation areas, we can take care of this too.

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

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

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.
