Why Larchmont Homeowners Choose GCMM for Basement Renovation
The biggest mistake homeowners make with basement renovations is finishing over moisture problems. At GCMM, every Larchmont basement project starts with a thorough moisture assessment. We check for water infiltration, condensation, and humidity levels before recommending the right waterproofing, insulation, and vapor barrier strategy for your specific conditions.
Once moisture is controlled, we build your basement to the same standard as the rest of your home — proper framing, electrical to code, insulated walls, smooth drywall, quality flooring, recessed lighting, and paint. The result is a comfortable, dry, finished basement that adds real living space and value to your Larchmont home.

How much does a basement renovation cost in Larchmont, NY?
Basement renovation costs in Larchmont typically range from $25,000 to $70,000+ depending on square footage, complexity, bathroom addition, and finish level.

How long does a basement renovation take?

Do I need a permit to finish my basement in Larchmont?
Yes. Westchester County requires permits for basement finishing work that includes electrical, plumbing, framing, or creating habitable space. Egress requirements (emergency exit windows) must also be met for bedrooms. GCMM handles all permitting and inspections.
How do you handle moisture in basements?
Every GCMM basement project starts with a moisture assessment. Depending on conditions, we may install interior drainage systems, sump pumps, vapor barriers, rigid foam insulation (which acts as both insulation and vapor retarder), and dehumidification systems. We address the moisture first, then finish.
Can I add a bathroom to my basement?
Yes. We install full and half-bathrooms in basements using either traditional gravity plumbing (if the drain is accessible) or up-flush/macerating systems. We coordinate licensed plumbing and handle all tile, vanity, and fixture installation.
What about radon in Larchmont basements?
Radon is a legitimate concern in Westchester County basements. We recommend radon testing before finishing your basement. If levels are elevated, we can incorporate a radon mitigation system into the renovation design.
Are you licensed and insured?
