Zen windows replaced a window in our bathroom. From the first visit for a quotation to the final completion of the work everyone we dealt with was professional, helpful and a pleasure to deal with.

We recently used Zen Windows in Bristol to replace our old, broken wooden sash windows, and the entire experience from start to finish was outstanding. A fantastic local company with a brilliant team.

I had high hopes of Zen Window, an established and local family run business, having been recommended them by a friend. But they more than exceeded my expectations. Massive thanks from a delighted customer!
