Ashderg Contracts is a family-run business with a rich history dating back to its establishment in 1991 by Garth Armstrong. Initially focusing on contracts with the Road Service, they undertook patch reinstatements in Belfast for eight years before moving to the Newtownabbey section, where they held the contract for 28 years. More recently, Ashderg has secured a 5-year patching contract with both Newtownabbey and Antrim Councils.
In addition to their Road Service contracts, Ashderg has subcontracted work from Graham Construction, contributing to significant projects such as The West Link, The Shore Road to Carrickfergus, and the Toome to Magherafelt bypass. They have also diversified their portfolio to include private driveways and commercial works, showcasing their versatility. In the summer of 2023, the business passed to Richard and Robert Armstrong, who bring over 30 years of collective experience, specializing in large private driveways and road works.
With the new generation at the helm, Ashderg Contracts continues its legacy of excellence and commitment to quality workmanship in both public and private sector projects.
