Gas Line Services in Mahopac, NY

Wall-hung boiler installed with copper hydronic piping and expansion tank

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 tracking down leaks in Mahopac since 1980, out of our shop on Bucks Hollow Road.

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 skip pressure testing before a line goes live.

Gas in Mahopac Specifically

The town isn’t uniform. Some neighborhoods have had natural gas service for years; properties further out, on the wooded lots and back roads, run on propane or still on oil. We move between all three situations regularly — a conversion in one part of town, a propane tank-to-appliance install in another.

Oil-to-gas conversion is the single biggest driver of gas calls we get here. As mains have extended further, homeowners with aging oil boilers see the chance to switch: lower long-term maintenance, no more tank deliveries, often better efficiency. The job starts with confirming main access at the property line, then interior piping, decommissioning the old oil equipment, and a pressure test before the utility sets the meter.

Where there’s no main nearby, propane is the standard alternative. Tank placement, interior line sizing, and appliance connections follow the same code requirements as natural gas — just a supplier-filled tank instead of a utility meter.

What We Install and Repair

New gas line installation for additions, renovated kitchens, and finished basements. Kitchen lines for range conversions and relocations. Appliance hookups for dryers, fireplaces, pool heaters, and standby generators — the latter increasingly common here given storm outages. Gas stove and oven installation. Boiler and furnace supply lines, usually alongside a heating job. Water heater connections. Outdoor lines for grills, fire pits, patio heaters, and outdoor kitchens, buried to proper depth with accessible shutoffs. Propane systems. Commercial gas work for local businesses.

On the repair side: gas line repair, electronic leak detection, gas safety inspections, and pressure testing.

If You Suspect a Leak

If you smell gas, hear hissing, or have any reason to suspect a leak, 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.

A leak doesn’t always announce itself with a smell, either. Older buried lines can develop slow leaks that show up as a dead patch of grass in the yard or an unexplained jump in gas usage. We use electronic detection to isolate the exact point of failure before opening a wall or excavating.

Permits and Inspections

Permit and inspection processes vary by municipality. We file directly with the relevant building department for each job and schedule inspections accordingly, so the work is documented and up to code rather than a problem for the next homeowner.

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 us right away.

Do I need a permit for a new gas line in Mahopac?
In most cases, yes. We handle the permit and inspection process as part of the installation.

Can you convert my Mahopac home from oil heat to gas?
Yes, it’s one of our most requested projects. We handle the new line from the meter, the appliance swap, and decommissioning the old oil equipment.

What if there’s no gas main near my property?
Propane is the standard alternative on the outer parts of town, and it follows the same code requirements as natural gas for line sizing, shutoffs, and testing.

Can you run a line to an outdoor grill or fire pit?
Yes. Buried or above-ground outdoor lines to grills, fire pits, patio heaters, and outdoor kitchens, with proper burial depth, shutoff access, and leak testing before you fire anything up.
