Serving Northern Virginia Homeowners Since 1936: Three Generations Strong

Plumbing systems rarely announce themselves until something goes wrong. Pipes and fixtures in Fairfax homes face real stress year-round: shifting soil, fluctuating water pressure, and decades of temperature swings. Northern Virginia housing spans several construction eras, and many homes in neighborhoods like Burke, Annandale, and Dunn Loring Woods have infrastructure that has outlived its original service life.

Long's Corporation has served Northern Virginia homeowners since 1936. As a third-generation, women-owned plumbing company with an A+ BBB rating, we provide same-day residential plumbing service with transparent pricing. Our licensed master plumbers are actively involved in day-to-day work, and we offer free estimates, financing options, and Spanish-speaking support to make every visit as accessible as possible for Fairfax County homeowners.

Our residential plumbing services include:

Why Small Leaks Become Expensive Problems

A slow drip under a sink or a slightly elevated water bill is easy to dismiss, but these are usually symptoms, not isolated events. A single drip per second wastes more than 3,000 gallons of water per year, and the secondary damage it causes to framing and insulation can cost more to fix than the original plumbing repair.

A pinhole leak in a copper pipe is often a sign of corrosion along the entire line. When water migrates behind walls, it doesn’t stay put. Moisture trapped in a wall cavity creates the conditions mold needs to establish within 24 to 48 hours. The result can include mold growth, wood rot, and structural damage that can dwarf the cost of the original repair. In older Fairfax County homes, several small leaks appearing at once usually means a water line is nearing the end of its service life.

We use modern leak detection methods to locate the source without unnecessary demolition. We’ve been finding and fixing hidden leaks in Fairfax County homes since 1936, including in homes with finished basements where moisture behind walls can go unnoticed for months. If the cost of repairs is a concern, financing options are available.

What Sewer Lines in Northern Virginia Are Up Against

Clay and cast-iron sewer lines are common in Fairfax County homes built before the 1980s, and both materials become more vulnerable with age. Clay is brittle and porous; cast iron develops internal buildup that narrows pipe diameter over time. Tree roots make things worse. Oaks, silver maples, and willows, all common throughout Fairfax County yards, are among the most aggressive species for working their way into pipe joints and causing blockages. Settling soil adds another complication, creating low points called “bellies” where waste collects instead of flowing freely.

These problems are frequently misdiagnosed as routine clogs until a camera inspection shows what’s actually going on. We start every sewer service with a camera inspection so you can see the condition of your pipes firsthand rather than taking our word for it. Video documentation gives you the full picture before any repair decision is made. As a Virginia DPOR-licensed plumbing contractor, we handle residential sewer and water line work to code, and we present our findings with no pressure attached.

Piping & Repiping for Fairfax County Homes

The right call on a plumbing repair depends on what’s actually behind the wall. That answer changes considerably depending on when a home was built. Homes from before the 1950s may have galvanized steel supply lines whose zinc coating has broken down from the inside out, causing rust buildup, reduced flow, and discolored water. Copper lines installed through the 1990s can develop pinhole corrosion in acidic soil conditions. When multiple pinholes appear in the same system over a short period, a full repipe is often the more cost-effective path than a series of individual repairs.

We evaluate the whole system rather than just the presenting symptom. That’s how we determine whether a spot repair or a full repipe is the better long-term value. Our decades working in Northern Virginia homes of every construction era mean we can often anticipate what materials are behind a wall before we open it, which can lead to fewer surprises and more accurate recommendations. When a full repipe is the right answer, we use PEX tubing: it resists corrosion, handles freeze conditions better than rigid pipe, and can be routed through finished walls with minimal disruption.
