Four Decades of Experience, Built on Trust
Founded in 1981, GHI-NYC began as a small family-run contracting company committed to honest work and dependable results. Over the decades, we’ve grown into a trusted name in New York City construction, serving clients throughout Manhattan, Brooklyn, Queens, the Bronx, Staten Island, and nearby Jersey City and Hoboken.
Our team combines traditional craftsmanship with modern techniques to ensure every project stands the test of time. We specialize in masonry, concrete, waterproofing, and structural repair, with an unwavering focus on safety, precision, and customer satisfaction.
At GHI-NYC, we measure success not by the number of projects completed, but by the relationships built and the trust earned within our community. Most of our work comes from word-of-mouth referrals — a reflection of our dedication to quality, reliability, and personal service.
We’re proud to continue serving our neighbors with the same commitment to excellence that has defined our company since day one.
