Local Plumbing
Plumbing & Heating in St. James
RG Fort & Sons has worked out of St. James since Peter Fort founded the company in 2002. This is the hamlet we know best — the tight lots off Lake Avenue, the 1920s Colonials that back up toward Deepwells Farm, the newer construction north of Route 25A, and the stretch of Moriches Road where the water table climbs as you drop toward Stony Brook Harbor.
Being local matters more in plumbing than in almost any other trade. When a supply line lets go at 11pm, the useful question is not who has the nicest website — it is who can be at the curb in twenty minutes with a shutoff key and the right fitting on the truck. From our shop on Jefferson Avenue, most of St. James is inside that window.
Our service area covers all of the 11780 ZIP — the blocks around the St. James General Store, the neighborhoods bordering Deepwells Farm County Park, Head of the Harbor, Nissequogue, the Flowerfield side of Mills Pond Road, and everything down to the Nissequogue River.
Local Conditions
What We See in St. James Homes
Every town on the north shore fails in its own way. These are the four issues we run into most often in St. James.
Galvanized Supply Lines
A lot of the housing stock around the Lake Avenue historic district predates 1960, which means galvanized steel supply piping. It corrodes from the inside out, so the first symptom is usually pressure loss in an upstairs bathroom rather than a visible leak.
Cesspool and Sewer Transitions
Parts of the Lake Avenue corridor have been brought onto sewer while surrounding streets remain on cesspools. If your block changed over, the house lateral and the trap connection are where problems show up first, and the permitting is different for each.
Cast Iron Drain Stacks
Mid-century homes here commonly still have the original cast iron waste stack. Fifty-plus years of scale narrows the pipe until a single flush backs up a first-floor shower. We camera the line before quoting so you are not paying to guess.
Unheated Crawlspaces
North-facing crawlspaces and the slab additions people put on in the 70s and 80s freeze first. Most of our January emergency calls in St. James come from one of those two places.

Common Questions
Frequently Asked Questions
Do You Charge Extra for Emergency Calls in St. James?
We answer the phone 24 hours a day. Because St. James is our home base, after-hours calls inside 11780 do not carry the travel surcharge we would need to add for the far end of the county. You are told the rate before we dispatch — never after the work is done.
My St. James Home Is on a Cesspool. Can You Still Replace My Water Heater?
Yes. A water heater swap does not touch your waste system. Where the cesspool does matter is drain work and any fixture you are adding — Suffolk County has its own requirements for those, and we will tell you upfront whether your project needs a permit.
How Long Does a Water Heater Replacement Take?
A straight tank-for-tank swap is usually three to four hours from arrival to hot water. It runs longer if the existing unit is in a tight closet, if the flue needs reworking, or if we find the shutoff valve is seized — which on older St. James installs happens fairly often.
Can You Get to Head of the Harbor and Nissequogue?
Yes, both are minutes from the shop and we work in them constantly. The larger properties out there often have well pumps, booster systems, or long runs to outbuildings, and we service all of it.
Are You Licensed to Work in the Town of Smithtown?
We hold Master Plumber license 48986-MP and carry full liability and workers' compensation coverage. St. James falls under the Town of Smithtown for permitting, and we pull permits in our own name for any work that requires one.
