Simon Dunster, Owner & Founder

“With over 20 years experience within the Window & Home Improvement Industry, I have witnessed, experienced and understand first hand, how this industry has acquired such a poor reputation and hence why “The Open Window Company” was founded. Our purpose and vision as a company is to demonstrate and offer an entirely different, transparent, easy & trustworthy method of improving your home through your “journey” with The Open Window Company.”

Simon Dunster, The Open Window Company

Simon and his team did a great job fitting some new timber windows for a Grade II property which many companies couldn’t offer. In contrast, Simon could not have been more helpful, sourced a really good product and gave us a great price. The fitting went very smoothly and they cleared up and took away the old windows. I would highly recommend The Open Window Company!
