The offer, in full
Most sump pump replacements are the same job: the pit is fine, the pipe is fine, the pump is dead. That job is $697, flat. Here is the whole of it, and here is the short list of things that are their own number.
A third or half horsepower cast iron pump, not the plastic unit we are pulling out. Those are what fail early doing a job cast iron should have.
The quiet type, on purpose. A standard valve slamming shut at three in the morning carries through the whole house, and a valve that stops closing is what kills the next pump.
The pipe from the pump up to where your discharge line already runs, where it needs replacing.
Out of your basement and onto the truck. You are not storing it in the garage for a year.
Five gallons into the pit, float up, pump on, water down, clean shutoff. It sounds trivial and it is the step that catches a float rubbing the pit wall.
A battery water alarm sitting on the floor beside the pit. If the pit ever wins, you hear about it upstairs instead of finding out through the carpet.
If the basin is collapsing, cracked or too small for a proper pump, it gets replaced. Most do not.
If the run to daylight is broken, buried under a flowerbed or frozen shut every January, that is its own job.
A second pump on a battery, for the outage that arrives with the storm. Worth its own conversation, and worth reading the Fairfax County part below first.
If the pump is living on an extension cord, it needs an outlet. We will tell you, and we will tell you what it costs.
Most basements need none of these. If yours does, you see that number in writing before anything comes apart, and you can say no and still have the pump for the price on this page.
If your home is in Fairfax County
A pump is electric, and the storm that fills your pit is the storm that takes the power out. That is the whole argument for a backup, and in Fairfax County you are not paying for all of it.
One visit, one crew. The new primary pump with everything on the list above, plus a second pump on a battery that keeps emptying the pit once the power is out.
| Pump and battery backup, installed | $3,200 |
|---|---|
| Of that, the backup the county counts | $2,503 |
| Fairfax County sends back half of it | −$1,251 |
| You are out | $1,949 |
The $697 pump is not on the county’s list, so it is not part of that refund. The backup is. You pay us in full first, then apply, and we itemise the backup on your invoice so the county has the line it asks for.

You qualify if
Your home is in Fairfax County.
That is the whole test. No income limit, no means test, no age or hardship requirement. Homeowners, renters, homeowner and condo associations and places of worship all count.
The only exceptions are commercial property, and addresses inside the Town of Vienna, the Town of Herndon or the City of Fairfax, which are separately incorporated. A Fairfax mailing address is not the same thing as the City of Fairfax, so check which one you are in before you rule yourself out.
Those are the county’s rules, not ours, and they are the ones who change them. Read the program page before you count on the money. We quote and invoice the same either way.

Before you book anything
A sump pump almost always tells you it is going, and it tells you weeks before it matters. Find yours below. Two of these you can fix yourself in ten minutes, and we would rather you did.
Unplug it. The float is the switch that rides up with the water, and it very often wedges against the pit wall or the discharge pipe. Free it and lift it by hand. If the pump runs, reposition the float. If it does not, the switch or the motor is finished.
The check valve. Water is draining back down into the pit through a valve that no longer closes, so the pump keeps re-pumping the same water until it works itself to death. Cheap part, and replacing it saves the pump.
During a two inch storm that is correct behavior. In a dry week it is a stuck float, a failed check valve, or groundwater that is genuinely that high, and the last one is worth looking at outside the house.
Thermal overload, or it is gone. Either way it is not going to save you during the next band of rain, and the next band is the one that finds out.
Look at where the discharge line leaves the house. A frozen outside end means the pump is running against a closed pipe until it burns up. There are freeze relief fittings for this.
Two minutes, no charge
Do this before you call anyone. It is the single most useful thing on this page.
If it passes, you are fine, and put a reminder in for March. If it fails on step two or three, that is the call. The long version is here, including what each symptom usually costs.
Why here, specifically
This is not a sales line. Three of these numbers are the county’s own.
Fairfax County publishes a homeowner’s guide to its marine clay soils and it is blunt: the clays shrink dry and swell wet, the swelling pressure can exceed the strength of a basement wall, and water percolates through them very slowly. Slowly means it sits against your foundation looking for the lowest point. That point is the pit in your floor.
Reagan National’s normal year is about 42 inches of rain. 2018 delivered 66. Fairfax County’s environmental office reported that by July 31 of 2025 the weather service had issued 16 flash flood warnings and 20 flood warnings for the county, beating the old record by ten, and said plainly that the same total now falls in shorter bursts.
That is the county soil and water district’s line, not ours, and it is the one homeowners should read twice. Gutters, grading and downspouts decide how much water your pump is asked to move. The pump is the last line, not the first.
Came out same day when our basement started taking water. Replaced the pump, tested it twice, and showed me what to listen for. No upsell, no drama.Sump pump
Honest about what needed doing and what did not. Told me my pit was fine and just the pump had gone. Half of what I was quoted elsewhere.Plumbing
They put in a quiet check valve because I mentioned the old one banged at night. Small thing, and I notice it every single time it runs now.Sump pump

Straight answers
Yes, for a standard replacement in a working pit, which is most of them. That covers the pump, the quiet check valve, the PVC, the haul away, the bucket test and the water alarm. The four things listed above are quoted separately and you see those numbers in writing before anyone touches anything.
Age plus behavior. Zoeller, who make a lot of the pumps in this area, put service life at seven to ten years. If yours is past seven, runs often, and the basement is finished, replace it on your schedule instead of the storm’s. That is the entire argument.
Please do, and it takes two minutes. Pour five gallons into the pit. The float should rise, the pump should start within a few seconds, the water should drop fast, and it should shut off cleanly without running dry. Then listen for water rushing back into the pit, which means the check valve. Do this in March and again in August.
It is the thing that matters when the power goes out with the storm, which is when it goes out. The pump and a backup installed together are $3,200. If your home is in Fairfax County, the county reimburses half the $2,503 backup portion, about $1,251, so you end up out about $1,949. The pump itself is not on the county’s approved list, so do not expect half of the whole bundle back.
No. There is no means test. It is open to Fairfax County homeowners, renters, homeowner and condo associations and places of worship. What it excludes is commercial property and anything inside the Town of Vienna, the Town of Herndon or the City of Fairfax. Two things catch people out: the work has to be finished and paid for before you apply, and it is first come, first served, so when the county’s money runs out you go on a waitlist. Those are the county’s rules and they can change them, so read their page before you count on it.
All of Northern Virginia. Fairfax, Loudoun, Prince William and Arlington counties, and the cities inside them. We are based on Lafayette Center Drive in Chantilly.
Call and we will tell you honestly. After a heavy rain the board fills up, so the answer in a dry week and the answer the morning after two inches of rain are different answers.
Good through October 31, 2026
A pump replaced on a Tuesday is a plumber and an invoice. A pump replaced during the storm is a plumber, an invoice, a restoration company and whatever was on the floor.
The offer. $697 covers a standard sump pump replacement in an existing, sound pit: a new cast iron primary pump, a new quiet check valve, new PVC to your existing discharge line where needed, removal of the old pump, a bucket test, and a battery water alarm at no charge. One per home. Say the offer when you book.
What is not in it. A new or deeper pit, repair or re-routing of the discharge line outside the house, a battery backup system, and any electrical work including a dedicated circuit. If your basement needs one of those, you get that price in writing before the work starts and you are free to decline it and take the replacement on its own.
The pump and backup together. $3,200 installed covers the replacement above plus a battery backup system. Fairfax County’s Flood Mitigation Assistance Program reimburses 50 percent of the battery backup portion, $2,503 of that price, which is about $1,251 back and about $1,949 net. The reimbursement is the county’s, not ours. It is first come, first served, the work must be paid for in full before you apply, and we cannot promise the county will pay you. The $697 pump is not an approved practice and is not reimbursed.
The rest. Residential only. Cannot be combined with other offers or discounts. Offer ends October 31, 2026. Fairfax County’s Flood Mitigation Assistance Program is the county’s program, not ours, and eligibility, funding and the Vienna and Herndon exclusions are theirs to set.
