• Every business has a real local address and published local roots. Its owner type shows only once a public record confirms it.
• Each profile links the dated public records we checked it against, and licensed trades need a current Virginia license.
• The order is editorial and never for sale. Paid Featured businesses are labeled and sit in a box above the list without moving anyone.
• Source-checked means we matched the profile against the dated public records in its Sources list. Owner-confirmed means the owner also confirmed the facts with us.

Ownership is the thing most plumber lists leave out, so each card here carries an owner label once a public record confirms it. Every company listed here is based in Mechanicsville. Herman Allen dates to 1954; its About page says Mr. Allen sold it in 2014 to Bantam's Plumbing Company, a 2021 trade profile says Bantam's runs it as a separate, wholly owned subsidiary, and the state license is held in Bantam's name at Herman Allen's Mongo Way address.

USA Drain Service on Old Church Road calls itself veteran-owned and operated. ANP Plumbing and Gas on Holly Road and Commonwealth Plumbing Systems on Mechanicsville Turnpike are single-office companies, but no public record we found names their current owners yet, so their cards show no owner label until one does. LSC Plumbing works from a home base in Mechanicsville with its license filed in Hanover County; its site says "Locally owned and operated", but no source we found names the owner.

One name you'll see in local plumbing ads isn't on this page: Blazer Heating, Air & Plumbing on Pole Green Road. Richmond BizSense reported that Southern Home Services, a Florida company majority-backed by the private equity firm Gryphon Investors, bought Blazer in May 2026 and kept its name. This directory lists independently owned local businesses, not chains, franchises or companies owned by outside investors, so since the sale Blazer isn't here.^{[1][2][3][4][5][6][7][8][9][10]}

We can't give you a fair local range yet, and we won't make one up. None of the plumbers listed here publishes a trip fee, a diagnostic fee or an hourly rate on its site, and we checked each one. National price tables exist, but they aren't Hanover prices, so we leave them out.

What moves the bill is easier to pin down. Ask about four things on the phone: whether there's a trip or diagnostic charge and whether it comes off the repair; whether the job is priced flat or by the hour; whether an after-hours rate applies (USA Drain, for one, says its emergency rate starts after 5 PM on weekdays and covers weekends); and whether a permit and inspection are part of the quote.

Parts are the other swing. A gas water heater swap needs the gas line reconnected by someone licensed for gas, and on a well or septic home the fix may run past the house. Get the quote in writing, with parts and labor separate, before work starts.^[5][11]

Most say they answer around the clock. Herman Allen's site says it offers 24-hour service. ANP's site says 24-hour emergency service is available. USA Drain advertises 24/7 emergency response, with the higher rate after 5 PM and on weekends. LSC Plumbing's site says it is open 24 hours a day, every day. Commonwealth Plumbing Systems doesn't advertise after-hours service, so it fits planned work better than a burst pipe at night.

Before you need any of them, find your main water shutoff. Turning it off stops a leak from getting worse while you wait.^{[1][5][6][8][12]}

Not every Mechanicsville house is on county water. Hanover County water and sewer reach part of the county; other neighborhoods rely on private wells and septic tanks. It changes who you call. To find out whether county lines run near your house, call Hanover Public Utilities at 804-365-6019, and know that any water or sewer construction on your lot needs a plumbing permit.

On county water, Public Utilities requires a vacuum breaker on each outdoor spigot and a backflow preventer on an irrigation system, tested every year by a licensed backflow tester. On septic, the county's advice is to have the tank pumped every 5 years.

Hooking an older neighborhood up to public lines is a big job. Inside the county's Suburban Service Area, owners can extend water and sewer at their own expense, and a neighborhood can petition for a service district with 80% of owners in favor. The county's own estimate is $35,000 to $45,000 per property for sewer and $20,000 to $30,000 for water, assessed over up to 20 years.^[13][14][15]

Hanover enforces the Virginia building code, which requires a permit before work on a home's water supply, drains or vents, and on fuel lines. Swapping a faucet or toilet without changing the pipes behind it is exempt. In an emergency, the plumber can start the repair and file the permit application by the end of the first working day after.

Water heaters are the common question. A gas or oil water heater isn't covered by the replacement exemption, so it needs a permit. The code doesn't settle a like-for-like electric swap, so call Hanover Building Inspections at 804-365-6040 before the job. Whoever pulls the permit hands the county a copy of their Virginia contractor license, which is one more reason to hire a licensed plumber.^[16][17]

Search the company on the License Lookup run by DPOR, Virginia's Department of Professional and Occupational Regulation. The record should be active and show the Plumbing (PLB) specialty, and show Gas Fitting (GFC) if the job touches a gas line or a gas water heater. Virginia ties each specialty to a master tradesman: PLB to a master plumber and GFC to a master gas fitter. Every plumber listed here holds PLB; our cards show each license number, class and specialties as we read them.^[11][18][19]

Virginia requires a Board for Contractors license with the Plumbing (PLB) specialty, backed by a master plumber, for plumbing contracting over $1,000.^{[11][16][17][18][19][20][21][22][23][24][25]}

• Is it the same job? Line the three quotes up by scope: the same parts, the same fixes, the same cleanup. A lower price that leaves something out isn't lower.^[11]
• Is it in writing, with changes in writing too? DPOR, the state board that licenses contractors, advises against relying on a verbal agreement. Any change to the job should be written down and signed by both of you.^[11]
• Who pulls the permit? Virginia's building code requires a permit for many jobs, including any gas or oil appliance swap. The quote should say who files it and whether the fee is included.^[16][17]
• What's the payment schedule? A deposit and payments tied to finished work protect you. DPOR says not to pay for the whole job up front.^[11]

• No license number, or the wrong specialty. Work over $1,000 needs a Virginia contractor license that matches the trade: Plumbing (PLB), and Gas Fitting (GFC) for gas. Hire someone unlicensed and you also lose access to the state's Recovery Fund.^[11][21][23]
• The whole price up front. DPOR and the BBB both warn against paying for the entire job before it's done.^[11][25]
• Cash only. DPOR's advice is to never pay in cash. A check or card leaves a record if something goes wrong.^[11]
• A deal that expires today. Pressure to decide on the spot is a warning sign the BBB names. A fair price will still be there tomorrow.^[25]
• A door-knocker who skips your 3-day right to cancel. If a seller shows up uninvited and you sign at home, Virginia gives you until midnight of the third business day to cancel in writing. This doesn't cover a company you called out yourself.^[24]
• Asks you to sign over an insurance check. The BBB says not to. Pay the contractor for finished work instead.^[25]
