Pick one and we will keep it short. Three taps and you are done.
We run calls seven days a week, and we answer the phone around the clock.
Last step. We will call you back to confirm the window.
An emergency deserves a person, not a web form sitting in an inbox. Call the shop and we pick up.
No heat, no water, an active leak, or a backed up main. These move to the front of the line, day or night, weekend or holiday.
Your request is in and somebody will call you back to confirm a window. Here is what we have:
59% of the roughly 7,598 homes in Chantilly went up in the 1980s and 1990s, and only two of the 26 areas we cover sit deeper inside that window. The 1980s alone built 44% of the place.
Our shop is in Woodbridge, about thirty-five minutes out. Chantilly is one of the few towns where a residential van and a commercial truck leave for the same place on the same morning. Greenbriar and the streets around it are eighties and nineties housing, while the Sully Road corridor and Westfields are offices, flex buildings and restaurant kitchens, which run on a different clock.
Polybutylene went into American houses from 1978 until roughly 1995. The 1980s account for 44% of homes in Chantilly, more than any other decade, and the 1990s carry most of the rest of that 59%. So the first question we ask at a Chantilly address is what colour the pipe is at your water heater.
A build era is not a material, and we will not pretend it is. Plenty of these houses went in with copper. Others have been repiped since. Nobody reads the pipe off an address, us included. The share just buys you a reason to walk downstairs and look. What each material does as it ages is the long version.
Chlorine in treated water does the damage, working on the inner wall of the pipe and harder still on the acetal fittings at every joint. Cracking starts microscopic and spreads where nobody can see it, then a fitting opens under full line pressure. Galvanized warns you for years by going weak. Copper stains a joist first. Polybutylene gives you a ceiling on a Tuesday afternoon.
Polybutylene also went underground as a water service line, usually blue and sometimes black. Same chemistry, same ending, except the water surfaces in the lawn instead of the ceiling. If pressure dropped across the whole house rather than at one fixture, or the meter turns with everything shut off, that is a service line conversation and often a leak detection job first.
Replacing it takes a plumbing permit. Fairfax County's Appendix Q schedule, effective July 1, 2026, lists Water Service, new or replacement or repair, at $77.70, and sets a base permit minimum of $141.75. The schedule does not say how those two combine, so anyone handing you a confident permit total has invented it. There is also a 10% technology surcharge per transaction, and sewer work on private property carries the same $77.70 line plus a state permit if the trench reaches VDOT right of way. Inspections run through the county's PLUS system, next business day on a request filed before 11:59 p.m.
23% of Chantilly has gone up since 2000, 14% of it in the 2000s alone. Those houses have young buried pipe and little wrong behind the walls. What they have is equipment finishing a first life cycle: builder-grade water heaters at around ten years, first-generation HVAC past twelve. If somebody tries to sell you a repipe on a 2006 house, ask what they found. Expect an answer about CPVC going brittle rather than a percentage.
At the other end, only 9% of homes here predate 1970, so the deep old-pipe work we do daily in a place like Annandale is the exception in Chantilly. Where it turns up it is cast iron drains finishing their service life and the occasional pre-1972 lateral, which we camera before quoting.
Fairfax Water describes its supply in its own FAQ as "moderately hard to hard (5 - 10 grains per gallon, or 84 - 170 mg/l)". Treat that as a range rather than a constant, because 2025 monthly lab results fell outside it both ways. At that level you get scale on the bottom of a tank and fewer years out of it than the sticker suggested. A softener here is a comfort and equipment-life decision rather than a necessity, and flushing the water heater yearly buys more than people expect.
Kitchens along the corridors are a real part of what we do here, and grease is the recurring subject. Fairfax County Code Chapter 67.1 requires grease interceptors cleaned as needed, meaning often enough that the line never backs up, and cleaning records kept three years and available for county review on request. That second half catches owners out. We jet kitchen mains after close and leave the paper trail behind. Commercial plumbing and mechanical has the rest.
Backflow is the other rule that catches owners here. In Fairfax County the annual test has to be done by a tester who is both DPOR-certified as a Backflow Prevention Device Worker and listed on the county's Authorized Vendor List. Two requirements, not one. Call with the address and we will tell you straight whether that test is ours to perform. More on backflow.
Housing this age is rarely on its original system. It got replaced once, often by whoever quoted lowest the week the old one died, and the finding we make most is equipment sized for a different house than the one it sits in. Oversized short-cycles and never pulls the humidity down. Undersized runs flat out in August and still loses the upstairs. A bigger condenser on the same ductwork solves neither, and a heat pump that disappoints in a cold snap is usually wrong on airflow rather than on the box outside.
Rooftop units fail on filters nobody changed and condensate nobody traced, which is the whole argument for a maintenance schedule on commercial equipment. And where an R-22 condenser is still running, house or building, each summer top-up is money you do not get back. We say so before selling the refrigerant.
One call covers plumbing and HVAC. Talk to somebody who has been doing this for decades.
