Complete Residential Plumbing Services in Woodbridge

We handle every plumbing issue a homeowner can face. Not just the easy stuff. From routine faucet swaps to full sewer line replacements, our licensed plumbers have the training and equipment to do the job right the first time.

Drain Cleaning and Clog Removal

Slow drains are more than an annoyance. Left alone, they turn into full blockages and sewage backups. We use professional snaking equipment and hydro-jetting to clear even the toughest clogs. Kitchen grease buildup, bathroom hair clogs, tree root intrusions in your main line. We’ve seen it all in Woodbridge homes, especially the 1970s and 1980s builds common in Dale City and Lake Ridge.

Water Heater Repair and Installation

No hot water? We diagnose and repair all major brands of tank and tankless water heaters. When repair doesn’t make sense anymore, we’ll give you honest advice on replacement options and handle the full installation. We size the unit correctly for your household so you’re not paying to heat water you’ll never use.

Sewer Line Services

Your sewer line is the most critical pipe in your home, and you probably never think about it until something goes wrong. We offer full sewer pipe repair and replacement, trenchless sewer pipe lining, camera inspections, and sewer line cleaning. If your yard smells like sewage or multiple drains are backing up at the same time, call us immediately.

Leak Detection and Pipe Repair

Hidden leaks waste water, drive up your utility bill, and cause structural damage. We use electronic leak detection equipment to pinpoint problems without tearing your walls apart. Whether it’s a slab leak, a pinhole leak in copper pipe, or a burst pipe emergency, we locate and fix it fast.

Our leak detection services save Woodbridge homeowners thousands in potential water damage.

Fixture Repair and Installation

Dripping faucets, running toilets, wobbly fixtures. These small problems add up. A single running toilet can waste over 200 gallons of water per day. We handle all faucet repairs, faucet installations, toilet repairs, and complete bathroom and kitchen fixture upgrades.

Sump Pump Services

Woodbridge sits in an area with a high water table and clay-heavy soil. That combination means many homes need a reliable sump pump to keep basements dry. We provide sump pump installation, sump pump repair, and battery backup systems so you’re protected even during power outages.

Gas Line Services

Gas leaks are serious. If you smell rotten eggs near your water heater, stove, or gas fireplace, don’t wait. We’re licensed gas fitters who handle gas line repair, new gas line installation, and gas appliance hookups safely and to code.

Water Treatment

Woodbridge water can be hard on your pipes, fixtures, and appliances. We install water softeners and filtration systems that extend the life of your plumbing and improve the water your family drinks and bathes in.

Garbage Disposal Services

A jammed or broken garbage disposal is one of the most common calls we get, especially around the holidays. We repair and replace all brands, and we’ll make sure it’s wired and plumbed correctly. Check out our garbage disposal repair page for more details.

Signs You Need a Plumber

Some plumbing problems are obvious. Others sneak up on you. Here’s when to pick up the phone:

• Water pressure has dropped noticeably
• Your water bill spiked without explanation
• You hear gurgling sounds from drains or toilets
• There’s a persistent sewage or musty smell
• Water stains on ceilings or walls
• Your water heater is over 10 years old and making noise
• Multiple fixtures are draining slowly at the same time
• You see wet spots in your yard that don’t dry up

If any of that sounds familiar, call us at (703) 491-6542 before a small issue becomes a big one.

Serving Every Neighborhood in Woodbridge

We’ve been in trucks driving these roads for over two decades. We know the plumbing quirks of every neighborhood:

• Lake Ridge: Mature trees mean root intrusions in sewer lines are extremely common. Many homes here have original cast iron or clay pipes that are reaching the end of their lifespan.

• Belmont Bay and Occoquan: Waterfront and near-waterfront properties face unique drainage and water table challenges.
• Marumsco and Westridge: A mix of slab and crawl space homes, each with different access requirements for plumbing work.
• Montclair and Dumfries: Newer construction mixed with established neighborhoods. We work on all of it.
• Potomac Mills area: Both residential and commercial plumbing needs in one of the busiest corridors in Prince William County.
