About us

Go Beyond with McQuillan Companies

It takes vision, ambition and innovation to look at an empty field and see a quarry. That’s exactly what John McQuillan did when he discovered limestone on his farm on the outskirts of 19th-century Belfast. Our story starts in quarrying, but we’ve embraced new opportunities in civil engineering, demolition, hazardous and non-hazardous waste management, outdoor cleaning and environmental testing. Adopting emerging technologies. Adapting to the changing needs of our customers, industries and communities. Leading positive change for more than a century.

We are driven by a passion for progress and technical excellence, with our skilled team leading the way in using advanced technology to succeed in everything we do. Guided by that spirit of innovation, our commitment to quality and the family values instilled in our business since the 1880s, we’re harnessing the power of our diverse services to secure a sustainable future.
