Personal, attentive service

At Diamond our focus has always been around giving our customers the very best personal service backed with the highest quality market leading products.

Our aim is to treat every customer how we would like to be treated. We’re happy when you’re happy, so we always go above and beyond to keep you that way. 

The local recommended company

At Diamond, we are the local company that cares, which is why we are now doing work for second and third generations of families from our very first customers over 25 years ago.

We understand that replacing your windows or installing a conservatory or kitchen is a major investment and you can have confidence that you will be choosing a local company that gets recommended by your colleagues, neighbours, friends or family members.  

In fact, around 90% of all our installations are due to recommendations from our happy customers.
