Basement Finishing
Westchester NY
Done Right.
That unfinished basement is the biggest untapped square footage in your home. J&J Remodeling turns it into a family room, home theater, gym, or guest suite built to last, without the shortcuts that lead to mold and water problems down the road.
Stop Storing Boxes in
Your Most Valuable Room
Most Westchester homes have a basement that is doing nothing but holding old furniture and holiday decorations. That is often 800 to 1,500 square feet of usable space sitting completely idle, while the rest of the house feels cramped. A finished basement is the most cost-effective way to add real living space to an older Westchester home without touching the roofline or the foundation footprint.
J&J Remodeling finishes basements the right way, starting with moisture control and proper framing before a single sheet of drywall goes up. We build family rooms, home theaters, playrooms, home gyms, guest suites, and basement bathrooms for homeowners across Westchester County who want their basement to finally pull its weight.
We work in the older housing stock found throughout Scarsdale, White Plains, Yonkers, New Rochelle, Bronxville, and the surrounding towns. Fieldstone foundations, low ceiling heights, and older sump systems are common here, and we know how to plan around every one of them.
“A finished basement does not just add square footage. It gives your family a room to actually use every single week.”

Basements Finished So
They Stay Finished
A basement is the one room in your home built partially below grade, which means moisture is always the real risk. Finish a basement without solving the moisture problem first and you are just building a beautiful room that will fail within a few years. That is not a mistake we make.
J&J Remodeling has finished basements across Westchester County in homes ranging from 1920s fieldstone foundations to newer construction. We know how to spot a moisture problem before we frame over it, how to size a sump system correctly, and how to keep ceiling height usable in older homes with lower joists.
Moisture Assessed First
Every basement project starts with a real assessment of drainage, grading, and existing moisture before we plan a single wall.
Code-Compliant Egress
Any basement bedroom gets a properly sized, code-compliant egress window, planned and permitted correctly the first time.
Smart Ceiling Planning
We route ductwork, plumbing, and electrical to preserve as much headroom as possible in basements with lower ceiling heights.
Clean, Respectful Worksites
Dust containment and daily cleanup keep the rest of your home livable while we work below it.

How much does it cost to finish a basement in Westchester NY?
Basement finishing in Westchester County typically runs $30,000 to $50,000 for a straightforward family room with standard finishes, $55,000 to $80,000 for a basement with a home theater, wet bar, or added bathroom, and $85,000 or more for a full basement suite with multiple rooms and high end finishes. Cost depends on square footage, moisture conditions, ceiling height, and whether a bathroom or egress window is being added. J&J Remodeling provides a free written estimate after assessing your specific basement.
How long does it take to finish a basement?
A standard basement finish with framing, drywall, flooring, and lighting typically takes 4 to 6 weeks. Adding a bathroom, wet bar, or egress window extends the timeline to 7 to 10 weeks. Larger or more complex basement suites can take 10 to 14 weeks depending on scope. We provide a firm schedule before demolition and framing begin.
Do I need a permit to finish my basement in Westchester County?
Yes. Nearly every Westchester municipality requires a building permit to finish a basement because of the electrical, framing, and often plumbing work involved, and an egress window is required by code if you are adding a bedroom. J&J Remodeling handles every permit application and inspection on your behalf.
How do you deal with moisture and water issues before finishing?
Before framing begins, we assess your basement for moisture sources, grading issues, and existing cracks. Depending on what we find, we may recommend interior drainage, a sump pump, a vapor barrier, or exterior grading corrections. Finishing over an unresolved moisture problem is the single biggest mistake homeowners make, and we will not skip this step.
Can you add a bathroom to my basement?
In most cases, yes. It depends on your home’s existing plumbing layout and whether gravity drainage is possible or an ejector pump system is needed. During your free consultation we evaluate your basement’s plumbing access and give you a clear answer along with pricing before any work begins.
Is J&J Remodeling licensed for basement finishing in New York?
Yes. J&J Remodeling is fully licensed and insured in New York State. Every basement project in Westchester County is backed by general liability insurance and workers compensation coverage, and we handle all required permits and inspections directly with your local municipality.
Westchester Homeowners
Love Their Finished Basements
Real reviews from Westchester County homeowners who trusted J&J Remodeling with their basement.
“Our basement was pure dead space for years. J&J turned it into a family room and playroom the kids use every single day. They caught a moisture issue early and fixed it before it became a bigger problem. Could not be happier.”
“We added a home theater and half bath to our basement. The team handled every permit and the finished space looks better than the rest of the house. On time, on budget, and genuinely great people to work with.”
“Our old fieldstone foundation basement had some tricky ceiling height issues. J&J planned around it beautifully and we ended up with a home gym and office we actually use every day. Highly recommend.”
