Quick answers
- Call now: gas smell (utility/911 first), uncontrolled water, sewage in living space, burning smell / hot breaker, no heat below freezing, CO alarm.
- Morning OK: slow tank weep (shut cold supply), no hot water without leak, one clogged fixture with a second bath, most AC outs unless vulnerable household + mid-80s indoors.
- Don’t pay emergency rates for: dripping faucet, running toilet, one-fixture low pressure, old-but-working heater.
- We answer 24/7; if we can’t roll tonight you get priority first-truck morning placement — and we’ll tell you if it can wait at the normal rate.
When to use this guide
Use this when deciding whether to pay an after-hours premium or sleep until morning — for plumbing, and for related HVAC/electrical safety flags.
Call someone right now
Gas smell — leave, call the gas utility emergency line or 911; don’t flip switches; plumber comes after the utility makes it safe. Uncontrolled water — shut the main; if the valve is seized or missing, that’s a 2 am call. Sewage into multiple fixtures (or your only toilet won’t clear) — stop all water use and call. Burning smell / hot breaker — shut the breaker (or main) and call; smoke/flame → 911. No heat below freezing — pipes are at risk. CO alarm — out of the house, 911, then HVAC.
Urgent, but next-morning is fine
Tank weeping from the bottom — close the cold shutoff on top, towels under it, first morning slot. No hot water / no water with no leak — morning territory. One clogged drain or toilet with a second bath available. AC out in summer — first available slot unless infants/elderly/medical and indoor temps past mid-80s. Furnace short-cycling, new AC noise, or rumbling water heater — schedule promptly (days, not hours). One dead outlet, no burn smell — reset breaker/GFCI once; if it trips again, leave off and book.
Can wait — keep your money
Dripping faucet, running toilet (close its supply), low pressure at one fixture, a heater that’s merely older than you’d like, odd thermostat, breaker that tripped once and stayed reset. Book a normal appointment.
What calling us after hours actually gets you
Live 24/7 answering. After-hours dispatch: $150 VA / $250 DC-MD. Daytime: $75 VA (waived with repair) / $150 DC-MD. We don’t always have a full overnight crew — if we can’t get there tonight, you get priority next-morning placement ahead of booked appointments. If what you describe is safe to wait, we’ll say so and book the normal rate.
Failure modes to avoid
Leaving water on “to see if it stops”
Minutes of flow destroy finishes. Find the main shutoff before you ever need this page.
Paying an emergency premium for a running toilet
Close the supply valve and book morning. We’ll tell you on the phone if that’s the right call.

FAQs
What are your after-hours fees?
$150 in Virginia and $250 in DC and Maryland. Daytime diagnostic is $75 in Virginia (waived with repair) and $150 in DC/MD.
Should I call for a slow water heater leak?
Shut the cold supply on the tank, contain the water, and take the first morning slot unless it’s dumping freely.
Where’s my main shutoff?
Usually where the water line enters — basement wall, crawl, garage, or near the meter. Every adult should know it before winter.
