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.

We had Christian from Benjamin Franklin Plumbing service come out to fix a leak in our home. He was patient, explained the procedure thoroughly, on time, and cleaned up the mess. We were pleased with his work.

Love the updates! Everything works perfectly!. The family is so thankful for the new complete water pipes lines, the new waterless tank, the toilet tank repair and most of all the new tub and tiles! The sink doesn’t backup anymore and the water taste so so much better! The metal taste is gone! The toilets don’t flush themselves anymore and the rattling of the pipes doesn’t exist anymore! Their master plumber is awesome; he’s worth every penny spent and more! Gerald, Ryan and team did beyond our family expectations! 5 stars

José was very knowledgeable. He verified that the low flow problem with my old faucet was due to the faucet and not in the house plumbing before installing the new faucet that we had bought a couple of days earlier. My wife and I preferred the design of the new faucet, and José eliminated our worry that the new faucet might not fix the low flow problem. The new faucet is leak free and works great.

Christian our house to diagnose an issue. The water department called and said we were losing 1 gallon per minute of water, continuous use. Christian Came twice with one service charge. He discovered That we had two toilets that were each causing continuous usage. Together, the two toilets were equaling A loss of 1 gallon a minute! For a fair price He fixed both toilets And eliminated the issue. He was polite, caring, honest and prompt!

Johnathan has been outstanding so far as still have final phase to go. He grasped concept of what we wanted and helped bring it into reality. Johnathan has communicated well and made sure we understood each step as work has progressed. Also kudos to Zach and Tony for their hard work in getting it done! In a follow up review Johnathan met to check on work done so we could move on to Step 2. Details were discussed, and we are moving to the next phase. Thanks to Johnathan for continuing to work with us and guide our project successfully. Very satisfied to date.

Benjamin Franklin Plumbing of Savannah Metro recently completed the plumbing work for our bathroom remodel, and we were very pleased with the results. They re-piped the bathroom efficiently, kept us informed throughout the process, and delivered quality workmanship. The team was professional, respectful of our home, and made the entire process stress-free. We would gladly recommend them to anyone looking for reliable plumbing services.
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.
