Pick one and we will keep it short. Three taps and you are done.
We run calls seven days a week, and we answer the phone around the clock.
Last step. We will call you back to confirm the window.
An emergency deserves a person, not a web form sitting in an inbox. Call the shop and we pick up.
No heat, no water, an active leak, or a backed up main. These move to the front of the line, day or night, weekend or holiday.
Your request is in and somebody will call you back to confirm a window. Here is what we have:
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.

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.
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:
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.
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.
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.
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.
One call covers plumbing and HVAC. Talk to somebody who has been doing this for decades.
