Why it matters

A building project is a big deal

Your property needs work, and it has to be done well. Hiring a builder should not feel like a gamble.

I'm paying for work that doesn't turn out the way I wanted.
I'm chasing a contractor who doesn't call back.
My project drags on and stays unfinished.
I don't know who to trust with my building.

Pick the wrong contractor and you can lose money and time on a building that still isn't right.

Our story

Building you can count on

If you own a home or business on Staten Island, a building project is a big job. You want it built or fixed up right, on time, by people you can trust. Too many contractors are hard to trust and hard to reach, and that leaves you worried about losing money or being let down.

Mammoth Construction is a family owned business. The team has worked on over 100 projects, including award winning ones, and won the Chairman's Award in 2018 for the Angiuli/Gentile Building. Our projects have also won awards from the Chamber of Commerce of Staten Island.

Getting started is simple. Call (718) 984-3666 on a weekday between 8:00 am and 4:00 pm, book a time to talk, and then book your project with the team. You end up with a finished building you are proud of and a builder you can call again.
