Mission & Values

Blacklough is dedicated to delivering construction solutions that stand the test of time. Our mission is to build not just structures, but lasting relationships with our clients, partners, and communities. We strive for excellence in every project, ensuring safety, quality, and sustainability are at the forefront of everything we do.

Founded in 2000 in Dublin, Ireland, by Gerard Walsh and expanded into Boston by Gavin Walsh in 2019, Blacklough Construction is the premier provider of new build and remodeling services in Greater Boston and the South Shore.

Gavin began his journey in the craft in 2004, starting as an FAS (Foras Áiseanna Saothair) Apprentice Carpenter. In 2006, while still in his apprenticeship, he became a Foreman on several large jobs in Dublin. In 2008, he finished his apprenticeship and moved on to Project Management. In 2010, he became a director at Blacklough and continues in this role today.

In 2011, Gavin brought his skills to Boston, working as a carpenter. He became a foreman for Haycon in 2014 and then a Project Manager in 2017 for KCM.

In 2019, Gavin continued the Blacklough name by establishing Blacklough Construction Inc. in Boston, Massachusetts.

In 2022, Blacklough opened their office at 551 Dorchester Ave in Andrew Square, making consultations and sample viewing convenient for anyone in the market for Blacklough’s services.

With experience on over 50 projects in Boston, Gavin brings deep knowledge of his craft, a vast network of professional relationships in Boston, and a passion for achieving the vision of his clients.
