About us

Our Story

Mainstream Granite Ltd was formed in 2014 with the objective of filling a niche in the wholesale Natural Stone market place. We hand select and hold in stock an extensive range of opulent natural stones; Marble, Granites & Quartzites. Each one unique, with incredible patterns and stunning colours as created by nature.

We have since incorporated Quartz to our product range and we are proud to be the exclusive UK Distributor for Diresco Quartz. Plus with our new M-Quartz collection we have an extensive selection of Carrara, Callacatta and Mirror Quartz available.

With more than 25 years of experience in the industry we have great attention for detail and a passion for providing the best customer service to our clients.

Over the years we have grown! Moved to larger, tailor made premises and expanded our product range.

2022 saw us become the sole UK Distributor for Diresco Quartz. We are so impressed with the quality of this Quartz which boasts many unique characteristics! Diresco Quartz features revolutionary BIO-UV Technology which results in a Lower Carbon Footprint Quartz, suitable for Indoor & Outdoor use.

In 2023 we introduced our in-house M-Quartz collection. M-Quartz is a beautiful range of Breton made, High Quality Carraras, Calacattas & Mirror Quartz. M-Quartz is perfect for large scale development projects as well as individual installations.
