What We Do

Every Plumbing Service a Dulles Home Needs, One Call Away

Thirteen services, one phone number. Pick the one that matches your problem — each page explains what the job involves, what it depends on, and the questions homeowners here ask us most.

Emergency Plumbing

Water where it should never be — a burst line at 2 a.m., a toilet that will not stop, sewage rising in a tub. We talk you through the shutoff on the phone, then come out and stop the damage at its source.

Flooded floor? Start here.

Emergency Pipe Repair

A split supply line behaves differently from a slow leak: it moves fast and soaks everything in its path. We isolate the broken section, cut out the failed pipe, and fit a proper repair instead of a clamp-and-hope patch.

Split pipe spraying? Read this.

Plumbing Repair

The everyday list — dripping faucets, toilets that run all night, tired shutoff valves, a shower that lost its pressure. We find the worn part, explain the fix in plain words, and repair it so it stays repaired.

Got a nagging repair list?

Water Leak Detection

A meter that spins with every tap off, a warm patch on the floor, a water bill that jumped for no reason. We track hidden leaks with listening gear and pressure testing, then pinpoint the spot before any wall comes open.

Bill jumped suddenly? Look here.

Sewer Line Repair

Slow drains everywhere at once, gurgling toilets, or a soggy patch over the sewer run usually mean the main line itself is hurt. We camera the line, show you the footage, and repair or replace only the section that failed.

Every drain slow at once?

Drain Cleaning

Kitchen grease, hair, soap build-up, and the odd toy car — household clogs have personalities. We clear the line, check how far the build-up runs, and tell you honestly whether a simple cleaning solved it or something deeper is going on.

One stubborn drain? Start here.

Water Line Repair & Installation

The line from the meter to your house does quiet, constant work. Low pressure at every tap, a wet stripe across the yard, or rusty water after a still weekend can all trace back to it. We repair damaged runs and install new lines sized for the home.

Pressure low everywhere?

Water Heater Repair

Rust-colored hot water, a pilot that keeps quitting, rumbling from the tank, or a puddle that keeps reappearing. Many heater faults are a single failed part. We test the components first and repair what is actually broken.

Hot water acting up?

Water Heater Replacement

When a tank is leaking from the body, badly corroded, or costing more to nurse along than it is worth, a planned swap beats a flooded utility room. We size the new unit to your household and haul the old one away.

Tank on its last legs?

Water Heater Installation

Building an addition, finishing a basement, or putting hot water somewhere it has never been? New installations need venting, supply runs, and placement planned from scratch — different work from swapping a dead unit, and we treat it that way.

Adding hot water somewhere new?

Tankless Water Heaters

Endless hot water and a smaller footprint, with homework attached: gas line sizing, venting runs, and yearly descaling in our mineral-heavy water. We install tankless systems and maintain the ones already on corridor walls.

Curious about going tankless?

Bathroom Plumbing

Toilets, tubs, showers, vanities, and the pipes hiding behind all of them. From a rocking toilet that is quietly rotting the floor to a full fixture refresh during a remodel, bathroom work is where small leaks do the most expensive damage.

Bathroom due for attention?

Kitchen Plumbing

Sink traps, disposals, dishwasher hookups, fridge lines, and the gas or water lines behind a remodel. Kitchen plumbing works hard every single day, and most kitchen floods start with a fitting nobody has looked at in years.

Kitchen project or problem?

Not sure which service fits what you are seeing? Describe the symptom instead — a noise, a stain, a smell, a bill that jumped. Call (855) 913-0016 and we will sort out the next step with you.

Diagnosis First

We Find the Real Cause Before Anyone Picks Up a Wrench Near Me

Plumbing symptoms lie. A slow drain in the kitchen can be a grease plug ten feet in — or the first whisper of a sewer line problem forty feet out. A stain on a first-floor ceiling in a Lowes Island townhome might come from the tub above, the toilet beside it, or a supply line two rooms away that only leaks under pressure. Guessing wrong costs you drywall, money, and a second visit.

So every job here starts with narrowing it down. We ask what changed and when. We check the meter against fixtures to separate supply leaks from drain problems. We use listening equipment and moisture readings on suspect walls, and a camera in drain and sewer lines so the diagnosis rests on footage, not hunches. In the corridor’s 1980s housing stock we also check pipe material early, because gray polybutylene changes both the urgency and the right fix.

Then we lay out what we found in plain language: what is broken, what it is doing to the house, what the repair options are, and which one we would choose in our own home and why. If the honest answer is “watch it for a month,” that is what you will hear. A clear diagnosis is the whole reason the repair that follows actually lasts.

Something feels off but you cannot name it? That is exactly what a diagnostic visit is for. Call (855) 913-0016 and we will sort out the next step with you.

Local Conditions

Plumbing in the Corridor Has Its Own Personality

The Dulles and Sterling corridor is not generic suburbia, and its plumbing problems are not generic either. Three local facts shape most of the work we do.

Townhomes, shared walls, and hidden shutoffs

From CountrySide to the stacked condos near Dulles Town Center, a huge share of corridor housing shares walls, floors, and sometimes pipe runs with the unit next door. Shutoff valves hide in utility closets, behind water heaters, or inside access panels previous owners painted over. We know where builders in each era tended to put them, and we work carefully around HOA rules when a building-wide shutoff is needed.

Loudoun Water runs hard

Loudoun Water supplies this area, drawing largely on Potomac River water. Hardness here lands in the moderately hard to hard band — roughly 80 to 170 milligrams per liter. That mineral load crusts faucet aerators, dulls shower doors, and settles as sediment in water heater tanks, where it cooks onto elements and shortens their working life. Annual heater flushing is not a sales line in this county; it is basic upkeep.

Pipe eras stack up street by street

Sterling Park’s original 1960s ranch and split-level homes are pushing sixty years of service from their plumbing. The 1970s and 1980s waves — Sugarland Run, older Sterling neighborhoods, early townhome communities — sit squarely in the polybutylene years. The 1990s and 2000s subdivisions around Cascades and Potomac Falls brought copper and early PEX, and Arcola’s newer builds use modern materials throughout. Knowing which era your street belongs to tells us what to look for before we ever open a wall.

24/7 Emergency Line

When Water Is Moving and It Shouldn’t Be, Minutes Count

Burst lines, overflowing toilets, sewage backing up, a heater dumping its tank across the utility room — these do not keep office hours, and neither do we. The phone is answered around the clock. We will get the water stopped first, talk you through it step by step, and then come deal with the cause.

  • Active leaks and burst pipes
  • Sewage backups
  • Overflowing fixtures
  • Failed water heaters
  • Total loss of water

Who We Are

A Small Local Outfit That Answers Its Own Phone

Dulles-Plumber exists for one pocket of Loudoun County: the Dulles and Sterling corridor, from Potomac Falls down through Arcola. We are not a regional chain routing calls through a distant call center, and this is not a satellite page for a company based three counties away. The people who answer the phone know that Sterling Park means 1960s construction, that a Cascades address probably means a 1990s tank nearing retirement age, and that a townhome off Route 7 likely hides its shutoff behind the water heater.

Our working rules are simple. Diagnose before quoting. Explain options in words a tired homeowner can follow at midnight. Do the repair we would accept in our own house. Leave the work area cleaner than the problem left it. Plenty of our calls come from neighbors of people we have already helped, and we would like to keep it that way — it is the cheapest advertising there is, and the hardest to earn.

New to the corridor, or just new to us? One call and you will know how we work. Call (855) 913-0016 and we will sort out the next step with you.

For Homes

House Calls Across Every Housing Era in the Corridor

Residential work is our bread and butter: the Sterling Park split-level with galvanized remnants and a tired main valve, the Sugarland Run townhome with polybutylene quietly aging behind the walls, the Potomac Falls colonial whose tank heater has started rumbling, the brand-new Arcola build where the builder-grade disposal gave up in year two. Each era fails in its own way, and we stock the truck for all of them.

Homeowners call us for repairs that need doing once and doing right, for leak hunts that protect floors and ceilings, and for planned upgrades — a heater swapped before it floods, a repiping job scheduled on your terms instead of a burst pipe’s. We protect floors, wear shoe covers in finished spaces, and walk you through what we did before we leave.

For Businesses

Commercial Plumbing for Corridor Shops, Offices & Restaurants

The corridor’s commercial strips — the restaurants and retail around Dulles Town Center, offices along the Route 28 corridor, gyms, salons, and medical suites tucked into Sterling shopping centers — run plumbing that works far harder than any house. A backed-up restroom or a dead water heater is not an inconvenience for a business; it is a closed door and a health-code conversation.

We handle commercial repairs, fixture work, drain problems, and water heater service for local businesses, and we schedule planned work around your hours where we can. When something fails mid-service, call — a flooded restroom at lunch hour is exactly the kind of problem our emergency line exists for. Property managers running corridor townhome rentals also lean on us for tenant calls, because we document findings clearly enough to close the loop with owners.

Common Problems

What Corridor Homeowners Actually Call About

The bill that makes no sense

A Loudoun Water bill jumps forty percent with no new baby, no guests, no pool. Nine times out of ten it is a running toilet, a leaking flapper, or a hidden supply leak — and our leak detection visit settles which one it is.

Every drain in the house slows down together

One slow drain is a clog; all of them together is a main-line story — roots, scale, or a damaged section. That is sewer line territory, and a camera inspection separates a cleaning job from a repair job.

Gray pipes in an eighties house

Buyers and owners across Sterling keep discovering gray plastic supply pipe stamped PB2110. It is the known troublemaker of its era. We inspect it honestly — some of it is still sound, some is living on borrowed time — and plan replacements before failures pick the timing.

The January burst

Cold snaps find the exposed line in the garage ceiling, the crawl space vent left open, the hose bib nobody drained. Winter freeze breaks are the corridor’s most predictable emergency, and a fall walk-through of exposed runs prevents most of them.

Recognize your house in any of that? Tell us the symptom and we will tell you the likely story behind it. Call (855) 913-0016 and we will sort out the next step with you.

Repair or Replace

The Honest Math on Fixing It Versus Swapping It

Almost every plumbing decision in an aging corridor home comes down to this question, and the answer depends on three things: the age of what is failing, how many times it has failed before, and what a failure would damage if it happened at the worst moment. A seven-year-old water heater with a dead element is a repair. A fifteen-year-old tank with rust at the seams is a flood waiting for a date — replacement is the cheaper conversation.

Pipes argue the same way. One polybutylene fitting letting go in an accessible basement is a spot repair and a warning. The third leak in two years, in walls this time, is the house telling you the system is done, and a planned repipe costs less — in money and in drywall — than leak number four. We will always price both paths when both are real, and we will tell you which one we would pick. What we will not do is sell a replacement to fix a fifteen-dollar part, or patch a system that is plainly at the end of its life.

Leaks

Hidden Leaks: The Quietest Expensive Problem in Loudoun Homes

A leak you can see is annoying. A leak you cannot see is a slow renovation of your subfloor, your framing, and your indoor air. In corridor townhomes it gets sneakier still: water travels along joists and pipe runs, so the stain on your ceiling may sit six feet from the fitting that is actually dripping, and in a shared-wall unit the source may not even be in your home.

The tells are consistent — a meter that creeps with everything off, a water bill climbing in steps, paint bubbling low on a wall, flooring that feels soft near a tub, a faint musty note that cleaning never quite removes. Our leak detection process pairs acoustic listening with pressure testing and moisture mapping to put a finger on the exact spot, so the repair opens the smallest possible hole. In slab and basement Sterling Park homes, that precision is the difference between a patch and a demolition project.

Suspect a hidden leak? The meter test takes two minutes — call and we will walk you through it. Call (855) 913-0016 and we will sort out the next step with you.

Drains & Sewers

From Kitchen Grease to Root-Cracked Mains: The Drain Story

Household drains fail in layers. Inside the house, it is the usual suspects: cooking grease cooling in the kitchen line, hair and soap in the shower trap, scale narrowing old pipe. A good drain cleaning clears that layer completely, and we check the full run so you know if the clog was a one-off or a habit the pipe is forming.

Outside the foundation, the story changes. Older Sterling sewer laterals pass under mature trees whose roots hunt moisture at every joint; Broad Run’s low, wet ground keeps soil around those pipes saturated; and decades of scale can narrow a line until one holiday dinner overwhelms it. When drains across the whole house slow together, gurgle, or back up at the lowest fixture, the problem has moved to the sewer line — and the right next step is a camera, not a bigger auger.

Water Heaters

Hot Water in a Hard-Water County: Tanks, Tankless & Timing

Loudoun’s mineral-heavy water is tough on water heaters. Sediment settles in tanks, bakes into a rumbling crust, insulates the water from the burner, and forces longer, hotter cycles that wear out elements, anodes, and eventually the tank itself. A heater that would cruise for fifteen years in soft water often tires years earlier here — unless it gets flushed annually and its anode rod checked before it is spent.

When a heater does act up, the path splits three ways. A failed element, thermostat, or valve on a sound tank is a repair. A corroded or leaking tank is a replacement, sized to how the household actually uses hot water. And households adding a bathroom, finishing a basement, or tired of rationing showers should look at tankless — provided the gas line and venting support it, and provided someone explains the yearly descaling our water demands. We handle all three paths and will tell you honestly which one your house is on.

Why Us

What Sets Dulles-Plumber Apart

  • Corridor-only focus. We work one pocket of Loudoun County, so we know its builders, its pipe eras, its HOA quirks, and where its shutoffs hide.
  • Diagnosis before demolition. Cameras, listening gear, and pressure tests first — walls come open only when we can point at the reason.
  • Plain-language options. You get the repair path and the replacement path with honest trade-offs, never a single take-it-or-leave-it number.
  • A real person answers. Day or night, the call reaches someone who can talk you through a shutoff, not a voicemail tree.
  • Townhome fluency. Shared walls, stacked plumbing, and association rules are our daily bread, not an edge case.
  • We leave it clean. Floors protected, work area wiped down, old parts hauled away. The only sign we visited should be plumbing that works.

Want to judge for yourself? One service call tells you more than any list like this. Call (855) 913-0016 and we will sort out the next step with you.

How It Works

From First Ring to Final Walkthrough, Near Me and No Fuss

Step 1 — The call. Describe what you are seeing. If water is actively escaping, we start with shutoff guidance before anything else is discussed.

Step 2 — The diagnosis. On site we test, listen, scope, or open exactly what is needed to identify the cause — and we show you what we find.

Step 3 — The options. You hear the repair and replacement paths in plain terms, with what each one does and does not solve.

Step 4 — The work. The agreed job gets done carefully, with the area protected and your household’s routine respected — including HOA access rules in townhome communities.

Step 5 — The walkthrough. We test everything under pressure, show you the result, note anything worth watching, and leave the space clean.

Prevention & Costs

Cheap Habits That Prevent Corridor Call-Outs — and What Drives a Bill

Most corridor emergencies are preventable with unglamorous habits. Flush the water heater once a year to beat Loudoun sediment. Know your main shutoff and turn it twice a year so it still moves when you need it. Drain hose bibs before the first hard freeze and insulate any line crossing a garage ceiling or crawl space. Keep grease out of the kitchen drain — wipe pans into the trash. And if your home has polybutylene, schedule an inspection on your terms rather than meeting it during a flood.

As for cost: honest pricing depends on what the diagnosis finds. The factors that move a bill are access (a valve in the open versus a pipe behind tile), pipe material and condition, how much of a system is affected, whether the work is planned or a midnight emergency, and any permit or HOA coordination a townhome job needs. We explain which factors apply to your job before work begins, so the number you approve is the number you pay. No invented price lists, no pressure — just the work your house actually needs.

Planning a job and want the factors priced out for your home? Call and we will walk the list with you. Call (855) 913-0016 and we will sort out the next step with you.

Questions

Dulles Plumbing Questions, Answered Plainly

Call (855) 913-0016 — we answer around the clock, every day of the year. On the call we will first talk you through shutting the water off, because stopping the flow matters more in the first five minutes than anything else. Then we arrange the visit that fits the situation, whether that is an emergency call-out or the first slot of the morning for something contained.

That pattern usually means water is escaping somewhere hidden — a toilet flapper leaking silently, a supply line weeping inside a wall, or the main line leaking between the meter and the house. A quick test: turn everything off and watch your meter. If the dial still moves, water is going somewhere. Our leak detection visit finds the spot before we open anything up.

It is worth a look. Homes built between the late 1970s and the mid-1990s across Sterling Park, Sugarland Run, and the older Cascades streets were often plumbed with polybutylene — gray plastic pipe that breaks down from the inside when exposed to chlorinated water. It does not fail on a schedule, but when it goes it tends to go suddenly. An inspection tells you what you actually have, and replacement can be planned instead of endured.

That is mineral scale from Loudoun Water. The supply here runs moderately hard to hard — roughly 80 to 170 milligrams per liter — so calcium settles on fixtures, inside aerators, and at the bottom of water heaters. It is not a health concern, but it shortens the life of heater elements and cartridge faucets. Flushing the water heater once a year and wiping fixtures with vinegar keeps it in check.

Close the main shutoff — in most corridor townhomes it sits in the utility room or basement near the water heater; in many Sterling Park houses it is in the basement or crawl space by the front wall. Then open a low tap to drain pressure, move anything water can ruin, and keep clear of standing water near outlets or appliances. Leave the rest to us.

Constantly — townhomes and stacked condos make up a big share of the Dulles corridor. Shared walls change the job: a leak in your unit can show up as a stain in your neighbor's, and shutoffs are sometimes inside your unit even when the pipe serves both. We coordinate access, check HOA requirements for water shutoffs, and document what we find so you have something clear to hand your association or neighbor.

Often, yes — but it is a conversion, not a swap. Tankless units need a correctly sized gas line or serious electrical capacity, new venting, and a condensate path. We measure all of that on the visit, tell you plainly if your house is a good candidate, and quote the whole job including the descaling routine our hard water makes necessary.

It can be. Around Broad Run and the low ground near it, saturated soil and high groundwater put pressure on older sewer joints, and roots take advantage of any gap. Gurgling after storms is an early warning worth a camera look — catching a root intrusion or a cracked joint early is far cheaper than a backup into the house.
