“Holdens Supaseal are our one and only supplier of double glazed units and have provided our business with this product for a number of years.

When initially choosing them as our supplier we went to the premises to meet them and to ensure that the company we were dealing with had the same high values and ethics that our own company believe in.

Their headquarters are extremely well run and efficient and they produce high quality units with excellent technical support. All the staff are very friendly and always willing to help. They are a solid reliable supplier and without doubt experts in their field.”

Having now been a customer for 5 years, we find all at Holdens very friendly and easy to get on with. Service is exceptional; if there’s a problem – it is solved.”
