Over 100 years ago, John McQuillan began quarrying limestone at Colinwell, so named because of the large natural spring well which rises at the site on the slopes of Colin Mountain.

Since then our Company has progressed from being a quarrying and aggregate processing company to being a walling product manufacturer.

Today, Colinwell Architectural Masonry and Facing Brick can be seen used on many buildings throughout Ireland and further afield.

We the fourth generation of the McQuillan family to operate our business from Colinwell, take pride in the knowledge that we are building our business on a tradition of quality, innovation and flexibility to meet challenging market demands.
