Plumber in Falmouth, VA
Ajax Plumbing is a father-and-son shop out of Front Royal. We run the length of Route 17 down to Falmouth for water heaters, drains, sewer lines and leaks. We pick up the phone, we show up, and we tell you straight.
Falmouth sits right where the Rappahannock starts to widen, on the Stafford County side of the river just north of Fredericksburg. It is one of the oldest settled spots in the region, and that age shows up in the pipes. We work the whole stretch, from the historic core near Route 1 out to the newer subdivisions off Warrenton Road, plus Stafford and Aquia Harbour up the road.
An old river town with old river-town pipes
From our shop at 266 Grove Farm Road in Front Royal, Falmouth is roughly an hour southeast. We take 522 down to I-66, drop onto Route 17 through Marshall and Bealeton, and follow it into Falmouth where it ties into Route 1 along the Rappahannock. It is a run we make often, because the housing stock down here gives plumbers plenty to do.
Falmouth is one of the earliest colonial settlements in Virginia, and the village core reflects that. You have homes near Cambridge Street and the old mill district that have been added onto across generations, which means a single house can hide galvanized steel from one era, copper from another, and a stretch of CPVC a previous owner ran himself. When something fails, the failure is rarely just one fitting. We trace the whole line, find the actual weak point, and tell you whether you are looking at a spot repair or a section of repipe. No guessing, no upsell on parts you do not need.

Move out toward Warrenton Road and the Falmouth side of Route 17, and the picture flips. Those neighborhoods went up in waves through the development boom, full of stick-built homes on slab and crawlspace with PEX and PVC throughout. The materials are newer, but the problems are real: builder-grade water heaters reaching the end of their warranty all at once, hose-bibs that split the first hard freeze, and main drains packed with grease and wipes because the original installs were never sized for how a busy family actually uses them.

Water down here is mostly municipal, served through Stafford County out of the Rappahannock supply, and that water carries enough mineral content to scale up a tank water heater faster than people expect. On the higher ground away from the county lines, you still run into private wells and the iron and sediment that come with them, which chew through fixtures, foul aerators, and shorten the life of any heater that is not flushed. We work both sides. We flush tanks, descale tankless units, and set up filtration when the water itself is the problem.
Falmouth winters split lines, every year
The Rappahannock corridor gets real cold snaps, and Falmouth’s mix of crawlspace homes and exposed exterior plumbing makes frozen and burst lines a yearly event here. A pipe in an uninsulated crawlspace or a hose-bib on a north wall is the first thing to go when the temperature drops into the teens. We run frozen-line calls all winter, and we knock 10% off frozen water-line repairs because nobody plans for a burst pipe in January. If you catch a line that froze but has not split yet, call before it thaws. That is the cheap fix. After it bursts is the expensive one.
We are backflow certified, which matters for the Falmouth homes with irrigation systems, well-and-municipal crossover, or any setup the county wants tested. We are also certified on most major water-heater brands, so whether you have a builder-grade tank from a Warrenton Road subdivision or a tankless unit in a renovated historic home, we can service it instead of telling you to replace it.
Residential plumbing repair in FalmouthResidential and commercial, every line in the house
Water heaters
Tank and tankless, repair and replacement. Falmouth’s hard municipal water scales tanks fast, so we flush, descale and swap units across every major brand.
Drains and hydro jetting
Slow kitchen lines, backed-up mains. We snake what a snake can fix and hydro jet the grease and root packs that a cable cannot touch.
Sewer line repair and camera
Older Falmouth laterals near the river take on roots and bellies. We run a camera, find the break, and fix the actual spot instead of digging the whole yard.
Leak detection and repiping
Mixed-vintage pipes hide leaks behind walls and under slabs. We locate them, then repair the section or repipe the run, your call once you see the truth.
Fixtures and gas lines
Faucets, toilets, valves, and gas line work for ranges, dryers and heaters. Clean installs that pass and hold.
Remodels and rough-ins
Kitchen and bath remodels in both the historic core and the newer Stafford subdivisions. We rough it in right the first time.

Straight answers
How fast can you get to Falmouth from Front Royal?
We are about an hour out, down 66 and Route 17. For scheduled work we set a window and keep it. For a true emergency, like a burst line or a sewer back-up into the house, we are a 24/7 shop and we move as fast as the road lets us. Call 540-671-5417 and tell us what is happening so we bring the right gear.
My Falmouth water heater is leaking. Repair or replace?
Depends on where it is leaking. A bad valve, element or fitting is a repair. Rust at the bottom of the tank means the tank is done and you are replacing it. We are certified on most major brands, so we will tell you honestly which one you are facing instead of selling you a new unit you do not need yet.
Do you do sewer camera work on older Falmouth homes?
Yes. The older laterals near the river core take on roots and develop bellies over the decades. We run a camera down the line, see exactly what is going on, and show you. Then we fix the spot that is failing rather than guessing or trenching the whole yard.
A pipe froze this winter. What now?
If it froze but has not split, call before it thaws so we can address it cheap. If it already burst, shut your main off and call us right away. We run frozen-line repairs all season and take 10% off frozen water-line work, because a January burst is nobody’s plan.
Do you handle commercial plumbing in Falmouth?
We do both. Residential service across the historic core and the newer subdivisions, plus commercial work for shops and small operations along Route 1 and Warrenton Road. Backflow certified for the testing the county requires.
Is the quote really free?
Yes. We come out, look at the actual problem, and give you a real number with no obligation. You can also start the conversation through our contact page if that is easier. See past jobs on our gallery.
