“Truly a remarkable team of people at Window Works. Their professional approach from the point of sale with our clients to the after-sales service is second to none in Ottawa. We often tell our clients that Marvin products are ‘money well spent’ in today’s window market. After more than 20 years of working with Dave and his team, we can’t recall a single window install that did not leave smiling faces on our clients’ when all was complete.”
