What a Northern Virginia plumber gets called for
- Water is escaping and will not stop
- Shut the main, then call. See pipe repair and leak detection, or emergency plumber after hours.
- Nothing drains, or several fixtures back up together
- One slow fixture is a branch line; two or more at once is the main. Start with drain cleaning, then sewer line repair if the blockage keeps returning.
- There is no hot water
- Control valves, elements, thermostats and tankless fault codes are diagnosed on site, never over the phone. Begin at water heater repair.
- A fixture drips, weeps or will not shut off
- Cartridges, seats, seals and shut-off valves wear out. Faucets, sinks, toilets and showers each have their own page in the lists below.
- The water pressure is wrong, or valves are failing all over the house
- That is one pressure problem wearing the whole system out. See water pressure, PRVs and shut-off valves.
Water heater plumbing services
Water heaters are the equipment we are called to most in this trade, and a heater that fails early usually failed because of something else in the plumbing — a missing thermal expansion tank, a spent pressure reducing valve, or copper joined to steel with no dielectric separation.
- Water heater repair
- Gas, electric, power vent and tankless units diagnosed on site — pilot assemblies, control valves, elements, thermostats, fault codes and sediment.
- Water heater installation and replacement
- Permitted work everywhere we serve: drain pan and pan drain, strapped expansion tank, isolation valves, correct venting and clearance, bonding restored across cut copper.
Drain, sewer and toilet plumbing repairs
| Service | What it covers |
|---|---|
| Drain cleaning | Mechanical cabling of the affected line, then a drain treatment for what the cable leaves on the pipe wall. |
| Sewer line repair and cleaning | Main-line blockages, root intrusion, bellied and broken laterals, and the excavation a failed line needs. |
| Clogged toilet repair | Cabled from the bowl first. A cable that jams past the fixture means the drain line, not the toilet. |
| Toilet repair and installation | Flappers, flush and fill valves, rocking bowls, failed wax seals and rotted closet flanges. |
| Garbage disposal repair | Jammed and seized units, leaking housings, and replacements set on a proper trap arm. |
| Sump pump repair and installation | Pumps that will not start or stop, undersized pits, float travel, check valves and discharge lines. |
Faucet, sink, shower and fixture plumbing
| Page | Typical fault |
|---|---|
| Faucet repair and replacement | Worn cartridges and stems, failed seats and seals, corroded shut-offs underneath. |
| Kitchen faucet repair | Drips at the base are body seals; weak flow is the aerator or spray head. |
| Bathroom faucet repair | A drip is a cartridge; water inside the vanity is the body leaking internally. |
| Outdoor faucet replacement | Stem drips, a weeping vacuum breaker, or a hose bib split over winter. |
| Shower faucet and valve repair | A dripping shower is nearly always the cartridge in the in-wall valve body. |
| Shower leak repair | Water escaping through the pan, the valve wall, the tile joints or the drain. |
| Shower and bathtub repair | Tubs holding water, failed waste-and-overflow assemblies, diverters and worn trim. |
| Sink repair and installation | Drain assemblies, tailpieces, traps, supply lines and the branch behind the wall. |
| Kitchen sink repair | Grease-loaded branches with no cleanout, split baskets, leaking disposal connections. |
| Bathroom sink repair | Hair and soap in the P-trap, failed pop-ups, supply valves seized open. |
| Dishwasher installation | A working shut-off, a braided supply that reaches, a high loop, a drain that will not siphon. |
Pipe, valve, water line and gas line plumbing
- Pipe repair and leak detection
- Hidden leaks found by elimination: fixtures and valves tested, the meter photographed and re-read after a hold period, then the wall opened where the evidence points.
- Burst and frozen pipe repair
- Stop the water, then correct why the pipe froze. Exterior walls, crawl spaces and unheated garages are where these happen.
- Water service line replacement
- The buried line from the meter or well into the house, replaced only once it is proven to be losing water.
- Water pressure, PRVs and shut-off valves
- Static pressure gauged on every plumbing call. A failed PRV is why a house suddenly leaks in several places at once.
- Gas line installation and repair
- Permitted work: hard-piped from the meter, sleeved through floors and walls, shut-off brought out where it can be reached, pressure tested for inspection.
Emergency and commercial plumbing in Northern Virginia
The phone is answered 24 hours a day, every day. A plumbing emergency is anything actively damaging the building or making it unsafe to occupy — a burst supply line, a sewage back-up, a heater flooding a finished basement, or the smell of gas. Emergency plumber covers how after-hours calls are triaged and what to shut off first.
Commercial work runs by other rules: the building cannot be shut down at will, the caller is rarely the owner, and the schedule bends around trading hours. Commercial plumbing covers restaurants, offices, retail units and multi-tenant buildings.
Plumbing permits, Virginia code and final inspection
Repairs generally need no permit. Water heater replacements, gas line work, water service line replacements and most re-piping do, in every jurisdiction we work in.
- We pull and process the permit ourselves — not handed back to the homeowner, with the fees written into the contract before the job starts.
- Work is performed to the Virginia building code. That phrase is on the great majority of contracts in our record, and it dictates the expansion tank, the pan drain, the sediment trap, the vent pitch, the bonding and the isolation valves.
- The final payment waits for the inspection. On permitted plumbing work the last portion of the contract is held until the county inspector passes the job.
- Labor carries a one-year warranty. Drain cleaning and drain repair are excluded.
Why one licensed company beats juggling separate trades
Plumbing rarely stays plumbing. Open a wall for a shower valve and there is drywall and tile to put back. Replace a water heater and the copper has to be re-bonded to the grounding system. Move a kitchen sink and the branch line, the wiring and the cabinetry move with it.
Sam & Sons holds Virginia DPOR class A contractor license #2705070610 and works in five trades with its own people. The company that pulls your plumbing permit also handles heating and cooling, electrical work, handyman and home repair and remodeling — one contract, one warranty, one number. We have worked here since 1999, mostly on single-family homes, with condos, townhouses and commercial buildings alongside them. Towns are listed on service areas.
How plumbing work is priced, and why not by phone
We do not quote plumbing prices by phone or publish them. Two houses with the same symptom become different jobs once access, pipe material, water pressure and whatever the last installer left behind are taken into account. An estimator comes to the property and puts a written price in front of you before anything begins.
