When you’re thinking about remodeling your basement here in Middletown, NJ, it’s not just about drywall and flooring, it’s about making space for what really matters. Whether it’s movie nights, a guest suite, or a teen hangout, the right contractor makes it happen.

Around here, we know how quickly the seasons shift, from those humid summer days at Poricy Park to blustery afternoons along the Navesink River. That means your basement needs to work hard all year, dry, comfortable, and functional, no matter what’s going on outside.

Choosing a basement remodeling contractor in Middletown isn’t just about price, it’s about trust, communication, and care. In our close-knit town, reputation matters. Let’s see who’s truly worth your time (and basement).

1. Renewal Solutions: Your Local Basement Remodeling Experts

At Renewal Solutions, basement remodeling isn’t a sideline, it’s what we do best. We’re a local team with deep roots in Monmouth County, and we’ve seen what basements in Middletown really go through. Our damp springs, muggy summers, and the occasional Nor’easter don’t do you any favors if your basement isn’t properly sealed and finished.

Our focus is simple: a dry, safe, and durable basement. No shortcuts, no one-size-fits-all.Our process starts with a walk-through and full moisture assessment, followed by a custom design tailored to how you actually plan to use the space. No pressure. No gimmicks. Just a team that listens.

And what we build? It’s made to last. We use mold-resistant materials, waterproof flooring, and energy-efficient insulation that helps keep those Jersey energy bills in check. Need egress windows for a legal bedroom or just want to keep the basement cozy without that “cold concrete cave” feeling? We’ve got you covered.

We also stand behind our work with a clear, reliable workmanship warranty. No surprises. No “oops, we missed that.” If something’s off, we fix it, because that’s what we’d want if it were our own home.

We’ve helped families from Chapel Hill to River Plaza turn forgotten basements into the best room in the house. Whether it’s a playroom, home office, guest suite, or something else entirely, we’re here to help you make the most of what you already own.

Got ideas? We’d love to hear ’em. Give us a call at (732) 788-4737 or contact us here to start the conversation. Let’s turn your basement into a space you’ll actually use.

Tom and his crew turned my dark basement into a living space and we were even able to add a full 3 piece bathroom. They were fast and finished in 3 weeks for a 4 week scheduled job. They were cool with last minute changes and mad no fuss at all which made me appreciate them more. Great team and will hire for future work.
