Chantilly addresses straddle the Fairfax and Loudoun county line, and the county a parcel sits in — not the postal town — decides who issues the permit and who supplies the water. On the Fairfax County side, permits come from Fairfax County Land Development Services through the PLUS portal and water comes from Fairfax Water. Sam & Sons Services is a licensed contractor based in Alexandria working across Northern Virginia in five trades. Call (703) 256-8080 and confirm your parcel before anything is scheduled.
Check which county your Chantilly address is in first
A Chantilly mailing address is not by itself proof of which county a property is in. Chantilly addresses straddle the Fairfax County / Loudoun County line, and it is the county — not the postal town — that determines the permit office, the water utility and the sewer authority. Confirm the county for your parcel before work is scheduled, because a permit filed with the wrong jurisdiction costs a week nobody planned for.
| If the parcel is in | Permits are issued by | Water and sewer |
|---|---|---|
| Fairfax County | Fairfax County Land Development Services, through the PLUS portal | Fairfax Water; public sewer run by Fairfax County DPWES |
| Loudoun County | Loudoun County Building and Development | Loudoun Water |
Permits for a Chantilly property in Fairfax County
On the Fairfax side there is no town office — Chantilly is a Census Designated Place in the unincorporated county. Residential building, electrical, plumbing and mechanical permits are separate applications, all made through the county's PLUS portal to Land Development Services, 703-222-0801.
We file each one under our Virginia contractor license, write the fee into the contract before the job begins, and hold the last portion of the contract until the county inspector has passed the work. A job touching two trades usually carries two permits and two inspections.
Water supply and hardness for Chantilly homes
A Fairfax County parcel here is supplied by Fairfax Water, which describes its water as moderately hard to hard — 5 to 10 grains per gallon, or 84 to 170 mg/l. That band of hardness is what scales heating elements, burner flues and tankless heat exchangers, and it is the reason flush intervals and anode condition decide whether a heater reaches its rated life. Below the heater, that hardness is also what jams a mixer cartridge: a handle gone stiff, or a spout still dripping after a washer change is the usual kitchen faucet repair or bathroom faucet repair call, and the fix is a cartridge rather than a new tap.
A parcel on the Loudoun side is supplied by Loudoun Water instead, so the Fairfax figures do not describe it. Either way, static pressure is gauged at the property on a plumbing visit — see water heater repair, water heater installation and water pressure, PRVs and shut-off valves.
Sewer, septic and drain problems around Chantilly
Public sewer on the Fairfax side is run by DPWES Wastewater Management, part of a countywide collection system of roughly 3,300 miles of pipe and 63 pumping stations. Countywide, about 24,000 Fairfax County homes use septic tanks instead of a sewer connection.
How much of the Chantilly area falls into that group is not something we will state as a blanket fact — it gets confirmed per property. If yours is on septic or a private well, the office is the Fairfax County Health Department's Division of Environmental Health, 703-246-2201, not Land Development Services. On public sewer, one slow fixture is a branch line and two at once is the main: begin at drain cleaning, escalate to sewer line repair, and treat a wet lower level as a sump pump question. A fixture that is slow by itself with everything else draining normally is not a line problem at all; it is the strainer or trap under a kitchen sink or the pop-up in a bathroom sink, cleared at the fixture.
What kind of property we work on around Chantilly
Countywide, Fairfax County counted 438,664 housing units as of January 1 2025 — 45.0% single-family detached, 24.1% single-family attached and 30.9% multifamily. That is the county mix, not a claim about any one neighborhood: what is actually installed at a Chantilly address is recorded by the estimator on site rather than assumed from the postcode.
Everyday plumbing follows from whatever is found there — toilet repair and installation, shower faucet and valve repair and pipe repair and leak detection are the calls that come in most, with emergency plumber covering the ones that cannot wait for morning. Behind those sit the routine jobs: a toilet that clogs or runs, a disposal that only hums, a dishwasher to be connected to supply, drain and circuit, and tub and shower repair when a diverter, spout or drain fails. A burst or frozen pipe is the one on this list that does count as an emergency; shut the main and call.

Handyman and remodeling jobs in Chantilly
Interior work is where most of the remodeling volume sits: kitchen remodeling, bathroom remodeling and the drywall and ceiling repair that follows any of it. Smaller handyman and home repair work is booked the same way and under the same license. That includes the door work no remodel gets around — interior and exterior door installation and fitting, pocket doors and barn doors, weatherstripping and draft sealing on an entry door that has shrunk from its frame — and bathroom regrouting and recaulking for a tiled bath that is sound apart from its joints.
Five trades across Chantilly and Northern Virginia
Sam & Sons Services LLC is based in Alexandria and has worked across Northern Virginia since 1999 under Virginia DPOR class A contractor license #2705070610. Plumbing, heating and cooling, electrical, handyman work and remodeling are all under one license, so a job crossing two trades keeps one contract and one warranty.
