5 Signs You Need A Plumber
- Gurgling noises – If while you’re using one plumbing appliance you hear a gurgle from another, then call in one of our plumber specialists pronto. What’s happening is that the air in your plumbing system isn’t ventilating, building pressure, and coming out of your toilet because it has nowhere else to go.
- Slow drains – If all of your drains are slow at the same time, then your main sewer line is most likely the culprit. If you have just one slow drain then you just need a good drain cleaning.
- Drip… drip… drip. – If you’re on a water meter, then call in an Plumber pronto as you’re literally throwing money down the drain. Even if you’re not on a meter, give us a call as a faucet that won’t stop dripping can be very annoying.
- Toilet won’t stop – If your chain is unhooked or obstructing your flapper’s seal, then simply re hook the chain or move it out of the way of the seal. If it’s not one of these quick fixes then call in a professional as there are a few different things it could be.
- Low water pressure – If you’re able to unscrew the faucet’s aerator and get at a clog yourself, then feel free. But do not try to unclog your fixture through the exposed end.
Plumbing Emergencies Northern Virginia Homeowners Should Never Wait On
Northern Virginia homes have their own plumbing quirks, and when something goes wrong, waiting it out usually means more damage and a bigger bill later. With older properties in Arlington and Alexandria, heavy clay soil in Fairfax, and freeze-prone crawl spaces in Loudoun and Prince William, certain problems just don’t give you much time before they turn into an emergency. If any of these show up in your home, it’s time to bring in a plumber right away.
Burst or Frozen Pipes
Cold snaps hit Northern Virginia hard, especially in older homes with exposed pipes in garages, crawl spaces, or additions. Once a pipe freezes or bursts, water spreads fast and can ruin drywall, flooring, and insulation.
Sewer Backups or Gurgling Fixtures
Tree roots are a big problem across NoVA—mature oaks and maples put real pressure on sewer lines in neighborhoods like Vienna, Falls Church, and Springfield. If you hear gurgling or see sewage backing up, that line may already be blocked or broken.
No Hot Water or a Failing Water Heater
Tank and tankless heaters work overtime in Northern Virginia’s mixed climate. Sediment buildup from hard water—common across Fairfax and Loudoun—can push a failing heater over the edge. If the unit’s leaking, hissing, or producing rusty water, shut it down and call.
Sump Pump Failure in Heavy Rain
Basements are common in NoVA, and many sit below the water table, especially in areas closer to the Potomac. When storms hit, a failed sump pump can flood a basement in minutes. Any grinding noise, cycling issues, or non-response deserves immediate attention.
Major Leaks or Rapid Water Pressure Drops
Older copper plumbing in Arlington, Alexandria, and older parts of Fairfax can develop pinhole leaks from age and water chemistry. If water pressure drops suddenly or you notice a fast leak, the issue may be behind a wall or under the slab.
Gas Smells or Gas Line Issues
Many Northern Virginia homes run gas water heaters, boilers, and ranges. Any gas smell is an emergency—leave the area, ventilate if safe, and get help immediately.
These issues move fast in Northern Virginia homes because of the climate, the soil, and the way the local housing stock was built over the years. When something feels off, don’t let it sit—getting help early keeps damage down and keeps your home safe.

Plumbing FAQs Nova Homeowners Ask
Do you provide plumbing service throughout Northern Virginia? Yes. Our plumbers serve the entire Northern VA region, including Fairfax, Arlington, Alexandria, Loudoun, Prince William, and all surrounding communities. Homeowners across Northern Virginia can expect fast response times and fully equipped technicians.
What plumbing issues are most common in Northern Virginia homes? Aging copper pipes, tree-root intrusion, hard water scale, sump pump failures, low water pressure, frozen pipes, and water heater breakdowns are some of the most frequent problems due to the area’s older housing stock, seasonal weather swings, and soil conditions.
Do you offer emergency plumbing repairs? Yes. Emergency service is available for burst pipes, sewer backups, major leaks, clogged drains, and water heater failures. Northern Virginia homeowners receive priority scheduling for urgent situations.
Can you repair or replace my water heater? Yes. We service all brands and models, including gas, electric, and tankless water heaters. Same-day repair or replacement is available in most cases, depending on the type of unit and parts required.
Do you provide drain cleaning and sewer line services? Yes. We offer professional drain clearing, hydro jetting, sewer camera inspections, sewer line repairs, and main line replacements. Tree-root growth and pipe settling are common issues in many Northern VA neighborhoods.
How do I know if my home needs repiping? Signs include rusty or discolored water, low pressure, recurring leaks, or older copper and galvanized pipes. Many Northern Virginia homes built before the 1990s develop pipe degradation over time. A repipe consultation can determine whether a full or partial replacement is needed.
Do you install and repair sump pumps? Yes. Sump pump installation, replacement, and troubleshooting are available for homes at risk of basement moisture or flooding—especially common in areas with high groundwater or heavy seasonal rain.
Can you improve my home’s water quality? Yes. We install whole-home water filtration systems, water softeners, and point-of-use filters for drinking water. Hard water is common in Northern VA, so filtration helps extend appliance life and improve water taste.
Do you help with kitchen and bathroom plumbing upgrades? Yes. We install faucets, sinks, showers, toilets, disposals, and handle plumbing rough-ins for remodels. Whether upgrading an older home or adding new fixtures, all work is done to code.
Do you offer clear pricing before work begins? Yes. Northern Virginia homeowners always receive upfront, transparent pricing with no hidden fees. Recommendations are based on what the home actually needs, not upselling.
