What Our Customers Say

★★★★★

FirstClass truly earned that name. They replaced our roof after storm damage with impeccable workmanship and left the property spotless. Professional from the first call to the final walkthrough — couldn't ask for more.

James Bellamy

Washington, NJ

★★★★★

I had a roof leak two other companies couldn't find. FirstClass located it within an hour using their moisture scanning and had it sealed that afternoon. Transparent, skilled, and completely honest. They've got my business permanently.

Karen O'Sullivan

Hackettstown, NJ

★★★★★

Used FirstClass for our commercial property in Phillipsburg. Their written warranty, clear communication, and quality of execution were all outstanding. On time, on budget, and zero disruption to our operations. Highly recommended.
