McAllister Group
About Us

McAllister Bros was established in 1971 and has remained a family run business for over 45 years. Started in Newry by the McAllister Brothers, the next generation of the family now direct the company. Core values such as reliability, trustworthiness, and being there to support the customer when needed most, remain at the centre of our strategy. In addition to this, the McAllister Group are early adopters of new equipment and techniques. We constantly maintain our position at the forefront of the technology curve. This allows us to solve problems ranging from the common up to the most challenging.

We are one of the leading providers of trenchless or No-Dig services in the UK and Ireland. We developed our maintenance and repair services to ensure minimal disruption to the area when we work. Aside from the standard tools of the trade, we have invested heavily in the latest trenchless technology with a vast range of specialised equipment. This enables us to perform tasks such as UV CIPP lining both faster, and on longer lengths of pipeline. A passion for excellence, an instinct to innovate and a desire to increase our knowledge and expertise. These are the motivating factors behind our constant improvement to the services we offer.
