Plumber in Woodbridge, VA

From a dripping faucet to a sewer main under your driveway, we handle the whole range. Family owned, Class A licensed, and answering the phone at two in the morning when the water will not stop.

Soldering a new copper water service line in an open trench

Most plumbing companies are comfortable up to a point. They will swap your water heater and snake a kitchen line, and then the job gets bigger and the answer becomes "you will need somebody else for that." We are usually who they send you to.

1 Stop Mechanical has been working on Northern Virginia plumbing for over forty years. That covers the small stuff you notice every day and the buried, expensive work most outfits will not touch: sewer laterals, water service lines, hydro-jetting a restaurant main that backs up every Friday night.

What We Handle

If it carries water, waste or gas in your home or building, it is on this list. Each of these has its own page with the detail:

Why People Call Us Second, Then Never Call Anyone Else

Two things separate a plumber who fixes it from one who keeps coming back. The first is diagnosis. A slow drain that returns every three months is not a drain problem, it is a slope problem, a root problem or a grease problem, and snaking it again just resets the clock. We would rather put a camera down the line once than sell you the same visit four times.

The second is scope. Because we run plumbing and heating and air under one roof, nothing gets handed off. When a water heater replacement turns into a gas line question or a venting question, it is the same crew and the same invoice.

Licensed, Bonded and Insured

1 Stop Mechanical holds Virginia Class A contractor license #2705131990. Class A is the top tier the state issues, with no ceiling on project value, and you can verify it yourself through Virginia DPOR. We carry full liability coverage and can send a certificate of insurance to any property manager or general contractor who needs one on file.

Straight Pricing, Before Anything Starts

We diagnose the actual problem, give you a firm number, and wait for you to say go. No hourly meter running while somebody decides what to do, and no discovering the price at the end. If there are two ways to solve it, a cheap one that buys you a year and a real one that buys you twenty, you get both numbers and you choose.

Serving Woodbridge and All of Northern Virginia

Home base is Woodbridge, so Prince William County is usually same-day. We run Fairfax, Loudoun, Arlington, Alexandria and the wider DMV daily. If you are on Prince William Water water and sewer, we work in your neighbourhood constantly.

Common Questions

Do you charge for a plumbing estimate?
We diagnose the problem and give you a firm price before any work starts, and you approve that number first. For a repair call there is a diagnostic visit; for a replacement quote like a water heater or a sewer line, the estimate is free.
Are you really available 24 hours?
Yes. Nights, weekends and holidays. A burst pipe or a backed up main does not wait for Monday, and a real person picks up rather than an answering service taking a message.
Do you work on houses as well as commercial buildings?
Both, every day. The same crew that jets a restaurant grease line will run a sewer lateral under a driveway in Lake Ridge. Homeowners get the entire service list.
Can you handle the permit and the county inspection?
Yes. Water service and sewer lateral replacements generally need a permit and an inspection, and we pull and schedule those as part of the job rather than leaving it to you.
