Sewer Line Services

Protecting Your Property From the Ground Up

A damaged sewer line affects every drain in your house and can lead to sewage backups, foundation damage, and costly landscape repairs. Keston’s Plumbing provides comprehensive sewer line services throughout Alexandria, Arlington, Fairfax, and the DC Metro Area. With more than 10 years of experience, full licensing through the Virginia DPOR, and training in modern trenchless methods, we solve sewer problems with minimal disruption — and we charge by the job so you know exactly what the work will cost before we start.

Sewer Line Camera Inspection

Every sewer diagnosis we perform in Northern Virginia begins with a camera inspection. We feed a waterproof camera through your line to pinpoint the exact problem — whether it is root intrusion, a collapsed section, grease buildup, or an offset joint. Camera inspection ensures you only pay for the repair you actually need.

Sewer Line Repair

Not every sewer issue requires a full replacement. Cracks, minor root intrusion, and isolated damage can often be repaired without replacing the entire line. We present your options with honest, flat-rate pricing after the camera inspection confirms the scope of the problem. All repairs are backed by our 30-day warranty.

Sewer Line Replacement

When a line is too deteriorated for spot repair — due to widespread root damage, bellying, or collapse — full replacement is the most reliable path forward. We coordinate permits and inspections, work with cast iron, PVC, and ABS piping, and size every replacement to meet current Virginia plumbing code.

Trenchless Sewer Line Technology

Traditional sewer replacement meant digging a trench across your entire yard. Trenchless methods have changed that. We offer two proven approaches that save Alexandria homeowners time, money, and property damage.

Pipe Lining (Cured-in-Place Pipe)

A resin-coated liner is inserted into the damaged pipe, inflated, and cured to form a smooth, jointless new pipe inside the old one. This method works well for cracks, root intrusion at joints, and moderate corrosion. The seamless interior surface resists future root penetration.

Pipe Bursting

When a pipe is too damaged for lining, a bursting head is pulled through the old pipe, breaking it apart while pulling a new pipe into position behind it. This replaces the entire sewer line with only small access pits at each end — no open trench across your yard.

Both methods dramatically reduce disruption. In many cases, work is completed in a single day and your lawn and driveway remain largely untouched.

Root Removal

Tree roots are one of the most common causes of sewer line blockages in Northern Virginia. Roots enter through joints and small cracks, growing until they obstruct the line. We use mechanical cutting equipment to clear root masses and restore full flow. For recurring problems, pipe lining can seal the entry points roots exploit.

Sewer Cleanout Installation

A sewer cleanout lets plumbers reach your main line quickly for clearing blockages and inspections. Many older Alexandria homes lack one or have cleanouts that are buried. A properly located cleanout saves time and money on future service calls. We install cleanouts to current Virginia code.

Signs of Sewer Line Problems

Sewer damage often develops gradually. Recognizing these warning signs early can prevent a minor issue from becoming a major emergency.

Slow Drains Throughout the House

A single slow drain usually points to a localized clog. When multiple drains — sinks, tubs, and toilets — are all slow at the same time, the problem is likely in the main sewer line.

Sewage Smell Indoors or Outdoors

A persistent sewage odor inside your home or yard indicates a crack or break allowing gases to escape — both a health concern and a sign of structural damage.

Wet Spots or Unusually Green Patches in Your Yard

Soggy areas or patches of grass growing faster than the rest of your lawn may point to a sewer line leak saturating the surrounding soil.

Gurgling Sounds From Drains or Toilets

Gurgling noises when you flush a toilet or run water suggest air is trapped in the line, often due to a blockage or partial collapse.

If you notice any of these signs, do not wait. Early diagnosis with a camera inspection is far less expensive than emergency excavation after a full backup.
