The $49 visit is waived when you go ahead with the repair. Pulling a pump just to look at it is $1,300 to $2,000, so we test the tank, the switch and the pump’s wire from the house first.
Replacing a pump needs no health department well permit in Virginia. We don’t drill or deepen wells; if yours needs that, we’ll tell you who to call.

What’s different in Sterling
Most of Sterling gets its water from Loudoun Water, which draws it from the Potomac River and, when it needs to, Goose Creek. Wells are the exception here, but they haven’t gone away. County well records still list 486 active household wells within three miles of the middle of Sterling, mostly in pockets the water mains passed by. If your house is one of them, the pump in the yard is doing the job a whole utility does for your neighbors.
Those wells have some age on them. More than half of the county’s records near Sterling date from before 1980, and the 1960s alone account for more of them than the 2000s and 2010s put together, by our count. Out around Waterford it runs the other way, with most wells going in after 1990. An old well can easily outlast two or three pumps, so the first thing we ask in Sterling is what’s been replaced and when.
They also run shallower. The median recorded depth near Sterling is 280 feet, against 350 for the county as a whole, though fewer than half of the records list a depth at all. Less depth means less pipe and wire to pull, and that helps the price. It says nothing about the condition of what’s down there, which on a well this old is the bigger question.
In September 2026 a Sterling homeowner came back from vacation to no water and a breaker that kept tripping. The pump had been down the well for more than 26 years. When we went to pull it, the threads on the pitless adapter, the fitting where the buried water line meets the well casing, were gone, and the pump wouldn’t come up. We came back and replaced the pitless adapter along with a new 3/4 horsepower pump, new 1 inch drop pipe and new wire.

|---|---|---|---|---|
| Sterling | 1979 | single-family houses, about 5 in 10 | electricity, about 5 in 10 | The well’s depth and what’s been replaced before. |
| Lowes Island | 1996 | single-family houses, about 6 in 10 | gas, about 7 in 10 | The tank first, then the pump’s age and wire. |
| Cascades | 1996 | townhouses, about 4 in 10 | gas, about 8 in 10 | The tank first, then the pump’s age and wire. |
| Sugarland Run | 1983 | single-family houses, about 6 in 10 | gas, about 5 in 10 | The tank first, then the pump’s age and wire. |
| Dulles Town Center | 1998 | condo and apartment buildings, about 5 in 10 | gas, about 9 in 10 | The tank first, then the pump’s age and wire. |
| Arcola | 2017 | townhouses, about 5 in 10 | gas, about 8 in 10 | The pressure tank and switch, often the originals. |
| Oak Grove | 2005 | townhouses, about 8 in 10 | gas, about 9 in 10 | The pressure tank and switch, often the originals. |

When to call
On an older Sterling well, the parts around the pump age right along with it: the pitless adapter, the wire splice, the drop pipe. Any of them can let go on the way up, and in Sterling they have. Ask what each would cost before the pull, so you’re not deciding in the driveway with the water off.
A pump that starts every few seconds usually means the pressure tank lost its air cushion. Every start wears the motor, so it’s worth a call this week, not next month.
Check the well pump’s breaker first. If it tripped once, reset it once. If it trips again, leave it off: the pump, its wire or the switch needs testing.
When the power goes out
The Virginia Department of Health puts it simply: if your home is on a well, the pump won’t work when the power is out. Here’s what to do before, during and after.
When a big storm is coming, fill a few jugs and the bathtub. Once the pump stops, all you have is what’s left in the pressure tank, and toilets need water to flush.
Many well pumps run on 240 volts. Franklin Electric’s installation manual says a transfer switch must be used any time a generator backs up a well pump, and VDH says to have the hookup made by a licensed electrician.
Franklin’s minimum for a 1 horsepower two-wire pump is a 6 kW generator, and 4 kW for a 1 horsepower three-wire pump. Not sure which yours is? The control box on the wall in the basement means three-wire.
Give the pump a minute to refill the tank. No water? Look at the well pump’s breaker. A surge can also take out the pressure switch or the control box, which we can test from the house.
VDH says to treat a well that was under floodwater as contaminated, and not to run the pump until its wiring is dry. Then shock chlorinate the well and test the water one to two weeks later.
Virginia Cooperative Extension recommends shock chlorinating after any repair to a well system, then a bacteria test one to two weeks later. A well’s water is the owner’s to look after: the EPA doesn’t regulate private wells.
Power back and still no water? Check the breaker, then call us. We’ll test the switch, the control box and the pump from the house before anything comes out of the well.
Who keeps the well records

Choosing who works on it
Questions to ask anybody who quotes you, us included.
Ask it straight out. On a well that’s sat untouched for decades, an old fitting or pipe giving way during the pull is a real chance. A good answer covers what it costs, how long you’d be without water, and whether they carry the parts.
Pulling a pump is the expensive part of the job. Ask whether they check the tank’s air charge, the pressure switch and the pump’s amp draw and wire from the house first, so you don’t pay to pull a pump that was fine.
Ask for the part that failed and its price, written down, before the pump comes up. If the price can change once the pump is out, ask what would change it, like worn wire or a bad pitless adapter.

Questions
Usually somewhat. The $2,781 to $4,000 row assumes the pipe and wire you already have, and less depth means less of both if they need replacing. On older wells the price moves on what we find, though. In September 2026 a worn pitless adapter turned one Sterling pump swap into a two-visit job.
Yes. VCE Loudoun runs a household water testing program with a $70 kit; the next sign-up is the 2027 waitlist. On a well surrounded by houses on public water, it’s easy to forget yours is the one nobody else is testing for you.
A new submersible pump on your existing pipe and wire runs $2,781 to $4,000 installed, and with new wire and drop pipe it’s $4,900 to $6,500. A pressure tank alone is $2,200 to $2,950 and a pressure switch is $450 to $609. You get the number in writing before we pull anything.
Not a well permit. Virginia’s private well rules say replacing a pump, or a well cap or seal with an equivalent one, isn’t a well alteration. Building, deepening or abandoning a well does need a health department construction permit.
