Celebrating 40 Years In Business

Celebrations are taking place at Reliant Windows in Oldbury as the team raises a glass to their 40th successful year in business.

In 1982 John Allen started the business, and today he is still managing director working alongside his son Nick. The business has grown and prospered thanks to the fantastic reputation it has among its customers – both domestic and commercial.

The company specialises in windows, doors and conservatories and says the key to their success has been their customers. Nick, who is marketing director at the company, says: “We are based close to the Black Country and Birmingham border, and this area has been great to us. Reliant Windows is still here, despite getting through some tough times. This includes the Covid pandemic, which affected us both personally and as a business.

Supporting The Local Area

Tiled Roof

“We are proud of the West Midlands area and so want to support the people that make it a great place to be. This includes Jonny Cole, who is a successful local comedian, singer and songwriter, and we have known him for several years. He is very positive about the Black Country and just the kind of person we want to get behind, and so we sponsor his breakfast show.”
