About Tarnwick
Leak detection in Petersburg begins with a phone number before it begins with a probe. Utility Billing, at (804) 733-2349, can confirm who owns the line to your house, and the City's Department of Public Utilities repairs City water meters, meter leaks included. Past that, the buildings decide the visit. They run from Old Towne's brick rows of the late 1700s to Walnut Hill's ranch houses of the 1960s, so the year the house went up comes first, and the meter with every fixture off says whether water is moving at all.
Locating is the whole visit. A typical house comes in at an estimated $150 to $400, set out in a written quote before anyone comes out, and any repair that follows is a separate quote from whichever plumber you pick. The marked spot and the evidence behind it are yours either way.
What we do

What is checked, and in what order
What we take on
The related lanes, with a range against every one.
All servicesWater Line Leak Detection in Petersburg
Water line leak detection in Petersburg starts with a question we do not answer for you: who owns the buried run to your house? Utility Billing at (804) 733-2349 can confirm the owner of your line before anything is priced.
Basement Leak Detection in Petersburg
Not every Petersburg house has a basement, so basement leak detection in Petersburg starts with what yours actually is: a full basement, a partial one, or a crawl space, which a technician checks as well.
Wall Leak Detection in Petersburg
Census-derived estimates put about one Petersburg home in six before 1940, and walls of that age hold plaster, brick and pipe added in stages.
Emergency Leak Detection in Petersburg
Emergency leak detection in Petersburg begins on the phone with the main shutoff and one question: is the water on your property or in the street? A break or valve problem on the street main is for the City's crews, and reporting it costs nothing.
Costs
Most houses land between an estimated $150 and $400 for detection. Where one lands depends on how many systems have to be ruled out and how hard the pipe is to reach, which is why the questions on the phone come first.

The route
A free quote by phone, and a written quote before any visit.
Call and describe what you see
Where the water shows, when it started, and what the meter does with every fixture off. That usually rules out a source or two before anyone drives over.
Get the figure in writing
The estimated range becomes a written quote for the visit, with any after-hours charge said up front. Nothing starts until you agree to it.
We isolate, then listen
Hot side against cold, house against buried line, one section of plumbing against the next. Then the equipment that isolation points to: pressure, acoustic, thermal, moisture or tracer gas.
You keep the finding
The spot marked, how it was found, what the pipe is made of and what the repair is likely to involve, in writing, for any licensed plumber you like.
Before you choose
A finding is only as good as the reasoning behind it, and these bring the reasoning out.
What is the estimated range, and what moves it?
Both halves. Detection sits at an estimated $150 to $400 for a typical house; a figure outside that should arrive with its reason.
Did they ask what the meter did?
Whether it turns with every fixture off is the first fact in this trade, and asking takes one sentence.
Is the repair quoted apart from the locating?
It should be. A combined number hides which of two different jobs you are paying for.
Will you tell me if there is nothing to find?
The meter often answers that before anybody arrives, and a business that says so on the phone is advising against its own short-term interest.
A small leak shows on the bill long before it shows on the wall, and the meter shows it before either.
Where we work
Petersburg and seven of its neighborhoods, each with its own page because the age of the buildings changes the first useful step.
Questions

Something not covered here?
Put it to us by phone. Plain answers, an estimated range and nothing to sign.
Call (804) 985-3290Start at the meter: every fixture off, then watch the low-flow indicator, the small dial or triangle that moves on the slightest flow. If it moves, close the main valve at the house and watch again to learn which side of that valve the water is on. Past that, the equipment takes over: a pressure test, listening and thermal imaging.
Four signs repay a closer look: a bill that jumped without a change in use, the sound of running water with every fixture off, a patch of floor, wall or yard that stays damp or warm in dry weather, and pressure that sags when two fixtures run. Any one is a reason to read the meter; two together are a reason to call.
For a typical house, an estimated $150 to $400, set out in a written quote before the visit and separate from any repair. Where it lands depends on how much has to be ruled out and how hard the pipe is to reach: a line under a driveway or a finished floor can run toward an estimated $300 to $800, and you hear that on the phone. No verified Petersburg average exists, so none is printed here.
Often because the reading or the meter is the problem and not a pipe. Compare the number on the bill with the register on your meter first. If they differ, or the meter itself is leaking, that is for the City: its Department of Public Utilities repairs City water meters, meter leaks included, and Utility Billing at (804) 733-2349 is the office to call. If the numbers match, turn every fixture off and watch the low-flow indicator; movement means water is leaving the pipes somewhere, and a toilet that keeps refilling is the usual indoor suspect.
Confirm it with the City before you spend anything, because we do not state the rule for you. What is documented is that the City's Department of Public Utilities repairs City water meters, including meter leaks, and Utility Billing at (804) 733-2349 can confirm who owns the line to your house. What we can do independently is show which stretch the water is escaping from, so that conversation is about a located leak and not a guess.
