Sewer Camera Inspection in Washington, DC

Good reasons to scope a line

• You are buying a house, especially an older rowhouse or detached home
• The main has backed up more than once
• A basement floor drain takes in water during heavy storms
• A plumber recommends hydro jetting, a liner or a full replacement
• You smell sewer gas and cannot find a source indoors
• A large tree sits near the route of the lateral

What the recording shows

The camera head usually carries lights and a sonde, a small transmitter that lets the plumber locate the head from the surface and mark the spot and depth of any defect. A good report notes the distance from the access point to each problem. Common findings include root intrusion at joints, cracked or broken pipe, offset joints, rust scale in cast iron, bellies where waste sits, and grease buildup.

Why older DC homes get scoped

The city's median home was built in 1957, and neighborhoods such as Capitol Hill, Mount Pleasant and Georgetown have far older houses. Many can still have clay or cast iron laterals that are hard to judge from inside the house. A buyer who skips the camera finds out about a failing lateral after closing. Since about a third of the District is on a combined sewer system, a lateral with a partial blockage also tends to show its weakness during summer storms.

Access matters

The easiest way in is a cleanout, often in the basement or near the front of the house. Without one, a plumber may go in through a toilet flange or a roof vent, which takes longer. If the line is packed with debris, it may need to be cleared first so the camera can see.

Reading the result

What affects cost

Price depends on access, line length, whether cleaning is needed first, and whether you want a recorded copy and locate marks. Always ask for the video file so another plumber can review it.
