Named Forbes' Top Ranked Plumbing Company of 2024!
Coal Mountain is a community in north Forsyth County, Georgia — one of the recognized named localities in the county that sits further north along the GA-400 corridor toward Dawsonville and the Lake Lanier shoreline. The area has seen steady residential growth as Forsyth County’s population has expanded, with a mix of newer subdivision development and older established properties on larger lots. Benjamin Franklin Plumbing® of Alpharetta serves Coal Mountain as part of our Forsyth County territory, bringing the same licensed, background-checked technicians and flat-rate pricing that serve our Alpharetta and Cumming customers.
Coal Mountain homes span a range of construction vintages. Older properties on larger parcels along established Forsyth County roads may have plumbing systems with multiple generations of partial replacement, and in some cases older well-to-municipal conversion service lines that are worth assessing. Newer subdivision homes built in the 2000s and 2010s are entering the stage where water heaters installed during original construction are reaching the end of their expected service life.
Water heaters in Coal Mountain homes are often a deferred maintenance item. The 10-to-12-year expected service life means many homes in the area are on second or even third generation units. Annual flushing to remove sediment from the tank floor extends service life and resolves the popping and rumbling sounds that indicate buildup on the heating element. For tankless units, annual descaling is manufacturer-required maintenance that should not be skipped. We are a Navien NSS certified installer and offer a 10-year parts and labor warranty on Navien tankless installations.
Water service lines on larger Coal Mountain properties — particularly older parcels that were formerly served by private wells — can be a source of slow, undetected leaks that show up first as unexplained water bill increases or wet patches in the yard. The private service line from the county meter to the home is the homeowner’s responsibility, and long rural service lines have more exposure to soil movement and more potential failure points than typical suburban lines. Directional boring allows us to replace the line underground without open trenching, minimizing disruption to driveways and established landscaping.
Drain cleaning is a routine service throughout Coal Mountain, particularly in older properties with cast iron or clay drain lines that have accumulated grease, scale, or root intrusion over decades. Camera inspection of the main drain line is the most accurate diagnostic tool before any drain repair or replacement is recommended.
The Forsyth County water supply from Lake Lanier is relatively soft, meaning hard water scale is not the dominant plumbing concern here. Water service line condition is worth attention for older properties, particularly those that were formerly on well water and transitioned to county service. The private service line from the meter to the home is the homeowner’s responsibility, and lines that are decades old on larger rural-to-suburban lots can develop leaks that are difficult to detect before they produce visible yard saturation.

All very nice people! They got me in the next day for a consultation and after giving the green light to fix my issues, the plumber was scheduled to come out same day. Benjamin was the consultant and he couldn’t have been nicer and explained everything to me. Especially for not being from here, but from Texas, I didn’t know a lot about how things are done differently bc of true winters. Vince and his partner did a Fantastic job rerouting my water line

Yes. Coal Mountain is within our Forsyth County service area and we dispatch from our Alpharetta location. We are fully licensed and insured in Forsyth County and can handle all residential plumbing work including permits and inspections. Call (678) 833-2754 for same-day service in most cases.
Yes — the private water service line from the county meter to your home is one of the first things worth assessing after a well-to-county transition. Older properties sometimes have the original well supply line repurposed as the service line, which may not be rated for continuous municipal water pressure. The meter box location and the line material, depth, and condition are all worth verifying. We can inspect the line visually and pressure-test the system to confirm everything is performing as it should.
Coal Mountain receives water from the Forsyth County Department of Water and Sewer, which draws primarily from Lake Lanier. The water is relatively soft and safe to drink. The most relevant treatment options are a point-of-use reverse osmosis system for drinking water — which removes disinfection byproducts and the trace PFAS compounds detected in Forsyth County’s 2024 water quality data at levels below EPA limits — and a whole-home carbon filter for taste and chlorine concerns. We are a Brita PRO authorized dealer and install and service both types of systems.
