Plumbing Services in Northern Westchester & Putnam County

Stainless steel double-basin kitchen sink with new faucet

Homes and businesses across northern Westchester and Putnam County count on steady water pressure, working drains, and heat that doesn’t quit in February. When something goes wrong, you need a plumber this area has relied on for generations, not a stranger’s van and a guess. DeGasperi & Son has been that plumber since 1980, our shop sits on Bucks Hollow Road in Mahopac, and we still answer the phone ourselves.

We handle the small stuff — a dripping faucet, a running toilet — and the big stuff, like a burst pipe flooding a basement. Our team is licensed, insured, and second-generation trained, which means the person diagnosing your water heater has likely seen the exact same model fail a hundred times before. Free estimates come standard.

What We Handle

Fixtures — faucet installation, toilet repair and replacement, garbage disposals, and full fixture work on tubs, showers, sinks, and hardware.

Water systems — tank and tankless water heater installation and repair, water line repair, filtration for hard water and sediment, well pump repair and replacement, and sump pump installation to keep basements dry through spring runoff.

Pipe work — leak detection and pipe repair, plus the two calls nobody wants to make: burst pipe repair and frozen pipe repair, both common here once temperatures drop and old insulation can’t keep up. A stain on a ceiling can mean a dozen different things, and finding the actual source without tearing the whole wall apart takes practice.

Commercial — routine maintenance and urgent repairs for local businesses, including backflow testing and prevention, scheduled around your operating hours where we can.

What to Expect When You Call

Call and you’ll reach our office directly. We ask a few questions — where’s the leak, how old is the fixture, is water actively running — so we bring the right parts the first time. You get a free estimate before any work starts, so you know the scope going in rather than after. And we clean up after ourselves: drop cloths, shoe covers, and hauling away old fixtures are part of the job, not an upsell. If something isn’t right after we leave, you call us back.

A lot of our current customers first phoned us when a parent or grandparent owned the house. That kind of repeat business doesn’t happen by accident — it comes from 45-plus years of knowing how homes here are built and what tends to go wrong in them, from well systems on the back roads to older copper in the village centers.

Plumbing Across Northern Westchester

Our shop is a short drive from the county line, which puts Somers, Yorktown Heights, Shrub Oak, and Croton Falls within easy reach.

No two of these towns share a housing profile. Yorktown Heights and Shrub Oak mix mid-century ranches with newer developments and older farmhouses off the main roads. Croton Falls skews rural, with larger lots and older housing that’s been added to over the years. Somers sits in between, suburban growth over a still-rural backbone. You’ll also find municipal-water subdivisions a few miles from properties still on private wells, so we handle both, often in the same week. In the older neighborhoods, aging clay pipe and tree root intrusion show up far more than they would in new construction.

Plumbing Across Putnam County

Putnam County is small towns, back roads, and homes built decades apart, which means the plumbing behind the walls varies just as much. A large share of properties, especially in the more rural stretches, run on private wells and septic instead of municipal service. Pressure tanks lose their charge, pumps fail on weekends, septic lines back up. That’s routine work for us, not a specialty add-on.

The lakes bring their own quirks. Seasonal homes need lines checked before reopening, higher water tables near the shoreline strain sump systems, and older cottages converted to year-round use often still carry pipe that was never meant to run through a New York winter. Inland, there are plenty of farmhouses with galvanized steel corroding from the inside.

Towns We Serve

Mahopac is home base — the shop is on Bucks Hollow Road and most of our calls come from town. From there our trucks run across the county line into Somers, Yorktown Heights, Shrub Oak, and Croton Falls, along with the wider northern Westchester and Putnam County area. If you’re not sure whether your street falls inside that range, call and we’ll tell you before you schedule anything.

If it’s a slow drain, drain cleaning is the faster fix; if it’s the boiler, our heating services team handles that.

Frequently Asked Questions

Are your plumbers licensed and insured?
Every plumber on our team is licensed and insured, and we’ve operated that way since 1980. You can ask to see credentials before any work begins.

Do you work on homes with well water and septic systems?
Yes. The rural edges of northern Westchester, and a large portion of Putnam County, run on private wells and septic rather than municipal service.

Do you handle commercial plumbing, or just homes?
Both, including backflow testing and prevention for local businesses.

Which towns do you actually serve?
Mahopac is home base. We also serve Somers, Yorktown Heights, Shrub Oak, and Croton Falls, along with the wider northern Westchester and Putnam County area.
