Gas Line Services in Northern Westchester & Putnam County
Gas line work isn’t a project for a general handyman or a weekend DIY attempt. It starts with proper licensing, pressure testing, and a crew that treats every connection like it matters — because it does. DeGasperi & Son has been running gas lines, connecting appliances, and troubleshooting leaks across northern Westchester and Putnam County since 1980.
Natural gas and propane both carry real risk when installed or repaired incorrectly. Our technicians hold the specialized licensing gas work requires, follow local and state code on every job, and never cut corners on pressure testing before a line goes live.
Installation
New gas lines for additions, renovated kitchens, finished basements, and standalone appliances, run from the meter or propane tank to the point of use, sized correctly and pressure-tested before anything connects. Kitchens are the most common: upgrading from electric to gas cooking, or moving a range during a remodel, means a properly sized line, an accessible shutoff, and clearances that meet code before we close a wall.
Beyond the stove we connect dryers, fireplaces, generators, and pool heaters, matching each hookup to the manufacturer’s specs. Standby generators have become a frequent request given storm outages here, and a correctly sized line paired with proper venting is worth having a licensed plumber do rather than treating as an afterthought. We also handle boiler and furnace supply lines — often part of a larger heating project — water heater connections, and outdoor lines to grills, fire pits, patio heaters, and outdoor kitchens, with proper burial depth and leak testing before you fire anything up. Where there’s no gas main, we install and service propane systems to the same standards.
Repair, Detection, and Inspection
Gas line repair calls usually start with a rotten-egg smell, a hissing sound near a fitting, or a dead spot in the yard above a buried line. We locate the problem, repair or replace the affected section, and pressure test before leaving. Corroded fittings, damaged buried lines, and old flex connectors are the usual culprits.
Leaks don’t always announce themselves — older buried lines can develop slow leaks that show up as dead vegetation or an unexplained jump in gas usage. We use electronic detection to trace the exact source rather than guessing and replacing parts. A gas safety inspection covers your meter, shutoff valves, visible piping, and appliance connections, checking for corrosion, improper fittings, and code violations. Worth doing when buying an older home or adding an appliance.
If you smell gas, leave the area and call your gas utility or 911 first. They can be on site faster than any plumber, and shutting down a live leak is their job. Once that’s handled, we can take care of the repair.
Gas Work Across Northern Westchester
Our work here covers Somers, Yorktown Heights, Shrub Oak, and Croton Falls, plus the surrounding hamlets.
Conversions drive a significant share of it. Gas infrastructure has expanded into more streets across northern Westchester in recent years, and homeowners on those streets are increasingly switching for lower maintenance, cleaner-burning equipment, and no oil deliveries or tank inspections to manage. A conversion is more than swapping the boiler: it means running a new line from the meter or street connection to the mechanical room, sizing it for the appliance load, and coordinating with the utility for the meter set and inspection. We manage that from initial line run through final connection and testing. Along the Route 6/202 corridor we also handle commercial work — kitchen equipment connections, heating system lines, and higher-capacity service installations with the additional code requirements those carry.
Gas Work Across Putnam County
Gas infrastructure looks different depending on which town you’re standing in. Some neighborhoods have had natural gas for years; the more rural stretches run entirely on oil or propane. Being based centrally in Mahopac means we move between both situations in the same week.
Oil-to-gas conversion is the single biggest driver of gas calls we get here. As mains extend further into the county, homeowners with aging oil boilers see the chance to switch — lower long-term maintenance, no more tank deliveries, often better efficiency. The process runs from confirming main access at the property line through interior piping, decommissioning the old oil equipment, and a pressure test before the utility sets the meter. Where no main is nearby, propane remains the standard alternative, following the same code requirements just with a supplier-filled tank. Permit and inspection processes also vary by town, so we file directly with the relevant building department for each job.
Towns We Serve
Gas and propane work takes us through Mahopac and out across northern Westchester to Somers, Yorktown Heights, Shrub Oak, and Croton Falls, along with the wider Putnam County area. How far the mains reach changes street by street out here, so the town pages cover what’s actually available where you are.

Frequently Asked Questions
Is it safe to smell a small amount of gas near my stove?
No amount of gas odor should be ignored. Turn off the appliance if it’s safe, ventilate the area, and call right away.
Do I need a permit for a new gas line?
In most cases, yes. Requirements vary by municipality, and we file with the relevant building department as part of the installation.
How long does an oil-to-gas conversion take?
It depends on the distance from the street connection and on utility scheduling for the meter set, but the plumbing portion is usually done within a few days once gas service is available.
What if there’s no gas main near my property?
Propane is the standard alternative across the rural parts of this region, following the same code requirements as natural gas for line sizing, shutoffs, and testing.
What should I do if I think I have a gas leak?
Leave the area, avoid switches or open flames, and call from a safe distance. If the odor is strong or you hear hissing, contact your gas utility as well.
