Drain cleaning in Marshall.

The County’s plan describes Anderson Avenue as about twenty one-and-a-half story frame houses from the 1920s to the mid-1940s, and Salem Avenue as mostly cottages. Those homes usually have one bathroom upstairs or tucked behind the kitchen, so the kitchen sink, the tub and the toilet all feed a single vertical stack. When the stack runs slow, every fixture in the house tells you at once.

Past the old streets, a tenth of Marshall’s owner homes are townhouses, in enclaves around cul-de-sacs south of Main Street, with a few condos and small apartment buildings on top of that. If your neighbor’s tub is slow as well, the clog may sit where your lines join. We’ll clear what’s yours and tell you if the cable runs into shared pipe.

North of Main Street, west of Rectortown Road, the neighborhood is mostly 1970s through 1990s, and the ZIP’s biggest decade was the 1980s. In those houses the drains are plastic, and a laundry line packed with lint or a kitchen line with fat in it is what we usually find. The garage often has a floor drain too, and it fills first when the main run is partial.

The plan says that some of Marshall’s soils hold a seasonal water table 10 to 40 inches down and that side-street runoff is handled haphazardly. A basement floor drain here can back up in wet weather even when the pipe is fine, because the water has nowhere else to go. If yours only acts up after rain, say so, since that’s a different problem from a clog.
