As well as honouring all our 10 year guarantee’s, we service the work of our 30,000 plus customers going back 35 years. It’s a boast that few of our competitors can match.

The relationship we enjoy with our old customers is something that Opus are also proud of. We have served generations of families and friends since we started trading in 1976 and through the years we have got to know many extended families and friends. They are so important to us and it’s what makes Opus the company they are today, providing us with more than 70% of our business. Thank you to our repeat customers.
