25 years of showing up for you, and now there's a new truck in the fleet 💚

This year Celtic Building Supplies turns 25. We're celebrating the way we know best: getting more materials to more jobsites, faster.

Our newest truck is already rolling express deliveries across NYC, Long Island, NJ and CT, loaded with safety, protection, masonry, lumber, drywall and tools.

When service matters, build with Celtic.

Celtic is proud to be a sponsor of Galbally Gaelic 4 Mothers & Others.

The club was selected as the only team from Co. Tyrone to compete at the New York Ladies Festival of Football, held at Rockland GAA on Saturday 10th October 2026. For a group of mothers and women balancing work, family and training, earning that spot is a serious achievement.

In our 25th year, supporting the GAA community here in New York is something we’re very proud of. Congratulations to the whole squad on flying the flag for Tyrone.
