More than just glass, support for your property

Owyn Northwood Glazing focuses on performance-led, energy-efficient glazing solutions in line with modern building standards. From Low-E and triple glazing upgrades to misted unit replacements and draught repairs, I help homeowners improve insulation, reduce heat loss, and boost property value without unnecessary full replacements. I also specialise in sash and heritage window repairs, patio door glazing, mirrors, splashbacks, and practical installations like cat flaps. With a strong “repair over replace” approach, many issues can be fixed cost-effectively, saving time and money. Whether it’s a period property or a modern home, I deliver honest advice, clear quotes, and flexible working hours to minimise disruption. As a local specialist, I focus on long-lasting results, fair pricing, and building trusted relationships with every customer.

Owyn did a fabulous job for us - repairing/adjusting a double glazed door so that it can be closed and opened easily again, replacing our misted window panel and replacing an entire window. He is very knowledgeable, friendly and kept us informed the way through - we highly recommend him!
