Plumber in Reston, VA

Reston is a planned community founded in 1964 by Robert E. Simon, laid out around village centers, lakes and wooded paths. Lake Anne Plaza was its first village center, and Reston Town Center later became its downtown. Housing ranges from 1960s and 1970s cluster townhomes to single-family homes, garden condos and newer high-rises near the Silver Line. We serve Reston with the same leak detection and repair approach we use across McLean.

Why plumbing in Reston is different

Reston's cluster design means many homes share walls, and many clusters have shared rules for exteriors. A leak in one townhome can show up next door, and finding the true source settles who needs to repair what. Many townhomes and some single-family homes are slab-on-grade or have water heaters in first-floor closets, so leaks show through floors rather than in a basement.

Much of Reston was built in the 1970s, 1980s and early 1990s. Homes from that era may have polybutylene supply pipe. Original water heaters, shutoff valves and supply hoses are often at the end of their life.

Common plumbing problems in Reston

Tips for Reston homeowners

• Know your shutoffs. Townhomes often have the main valve in a utility closet or under the stairs.
• Add a drain pan under closet water heaters on upper floors.
• Replace old supply hoses to washers, sinks and toilets with braided lines.
• Check for polybutylene if your home was built from the late 1970s to the mid-1990s.
• Read your cluster rules before changing anything on the exterior.

Water and permits in Reston

Fairfax Water supplies drinking water across much of western Fairfax County, including Reston. Fairfax County requires a residential plumbing permit for new or replaced plumbing equipment and fixtures, such as a repipe or water heater swap. We tell you what your project needs before we start.

High-rises and condos near Reston Town Center

Reston's newer mid-rise and high-rise buildings around Reston Town Center and the Metro stations bring condo-style plumbing problems. Units are stacked, so a toilet seal or shower pan leak can show up one floor down. Water heaters often sit in small closets without floor drains. If water appears on your ceiling, tell building management and the unit owner above, then shut off water to your own unit if the leak could be yours. We can test your fixtures and lines to show where the water is coming from.

Many Reston homes also sit near the lakes, ponds and stream valleys that give the community its character. Lower levels close to these areas see more groundwater after storms, so a working sump pump and a clear floor drain matter as much as the pipes themselves.

Reston plumbing questions

Do you cover all of Reston?

Yes. We serve ZIP codes 20190, 20191 and 20194, including Lake Anne, Hunters Woods, South Lakes, North Point, Reston Town Center and the neighborhoods near the Wiehle-Reston East and Reston Town Center Metro stations.

My townhome shares a wall. How do you find whose leak it is?

We test your unit's lines with the water shut off at your valve and check the shared wall with moisture and thermal tools. That shows whether the leak is yours or coming from next door.

Do Reston homes have polybutylene pipe?

Some do. Polybutylene was used in many homes built from the late 1970s to the mid-1990s, and much of Reston was built in that era. Look for gray plastic supply pipe.

Can I make plumbing changes without cluster approval?

Interior plumbing repairs usually do not need association approval, but exterior changes may. Check your cluster or Reston Association rules for anything outside, such as new hose bibs or vents.

Who supplies water in Reston?

Fairfax Water supplies most of the area. The line into your house from the street lateral is the homeowner's responsibility, which in a townhome cluster may be shared; check your association documents.
