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.
