Three generations. One family. Every job hand-checked by an owner.

For more than 50 years, Mario and Frank D’Alessandro have built a reputation as Long Island’s premier masonry specialists. From Nassau to Suffolk, we serve residential, commercial and industrial customers with quality craftsmanship at honest, competitive prices.

D’Alessandro & Son Contractors, Inc. is a masonry company that prides itself on professional customer service at every level. We want each client to receive nothing but the best — that’s why an owner is on every job, hands on every project.

Our work is client-oriented and referral-driven. It relies on quality installations, 5-star reviews and long-term relationships with the homeowners and businesses we build for.

Family owned. Fully licensed. Fully insured.

We install trusted industry brands including Cambridge, Techo-Bloc, Nicolock and Unilock — matched to your home, your budget and the way you actually use your outdoor space.
