Basement Finishing in Somers, NY

Westchester Basement Finishing Service Serving Somers

Family rooms, home gyms, offices and guest spaces for Somers lower levels, from colonials in Lincolndale and Granite Springs to Heritage Hills condominiums, permitted through the Town of Somers and run by one Guardian project manager.

Two Kinds of Somers Basements

Detached homes

Colonials and contemporaries from the 1970s onward, many with walkout or partly exposed basements on sloped, wooded lots. Most are on private wells and septic, which shapes what the basement can include.

Heritage Hills condominiums

Lower levels in Heritage Hills units come with an extra layer: the condominium association’s alteration rules and approvals, in addition to the Town’s permit.

Water, Rock and Reservoirs

Somers sits in the Croton watershed, surrounded by reservoirs such as Amawalk, Muscoot and Croton Falls, with streams and wetlands running through many neighborhoods. Combined with ledge rock near the surface on many lots, that means groundwater often finds the foundation in a wet spring.

We look for water history before we design anything: efflorescence on the walls, stains at the base, a sump that runs constantly. Then we fix the cause. Regrading or drainage work outside the house can involve watershed and wetland rules, so we check those before any digging.

Somers Basement Finishing FAQs

Who issues basement permits in Somers?

The Town of Somers Building Department. Permit applications are reviewed by appointment, and a finished basement is handled as an alteration. We prepare the floor plan and application and book the review.

I live in Heritage Hills. Can I finish my lower level?

Possibly. Heritage Hills is a condominium community, so in addition to the Town’s permit, your condominium association’s rules and approval for interior alterations apply. Ask management for their alteration requirements first; we work within them.

We're on septic. Can the basement include a bedroom?

Septic systems are sized by bedroom count, so a new bedroom on a septic system typically needs Westchester County Department of Health review. A family room, office or gym usually does not raise that issue.

How do you keep a Somers basement dry?

We start outside: gutters, downspout extensions and grading toward the house. Inside, we seal cracks, check or add a sump pump, insulate the walls with moisture-tolerant foam, and use a dehumidifier. We don’t put fiberglass against concrete.

Do Westchester basements need special insulation?

Westchester County falls in climate zone 4A under the NY energy code, and finished basement walls have to meet its insulation requirements. We build to code, and the inspector checks the work before drywall goes up.
