Most Detroit houses were built before 1950, and their drains show it. Bungalows in Rosedale Park, brick colonials in Boston-Edison, and two-flats in Southwest Detroit usually have cast iron drain stacks and branch lines. After 70 years or more, the inside of that pipe isn't smooth anymore. Rust scale and tuberculation create a rough, narrowed surface that grabs kitchen grease, hair, and soap residue. A drain that "only clogs once in a while" in a newer house clogs every few months here because the pipe itself is helping the clog form.
Your kitchen line takes the worst of it. Cooking grease goes down warm, cools inside the cast iron branch, and hardens in layers. A cable snake punches a hole through that buildup and restores flow for a few weeks. Our HydroScrub® jetting scours the grease and scale off the full pipe wall, which is why it's our go-to for kitchen lines that keep coming back. Before we jet an older line, we run a video camera inspection to confirm the pipe can handle the pressure.
Detroit's water adds to the problem. The city draws from Lake Huron and the Detroit River, and the water is moderately hard. Calcium and magnesium leave scale on faucet aerators, and the same minerals settle inside your drain lines over time. Scale by itself rarely causes a full blockage. It narrows the pipe and gives grease something to stick to.
Basement floor drains deserve their own mention. Detroit runs a combined sewer system, so stormwater and household wastewater share many of the same pipes under the street. During a heavy summer storm, that system surcharges, and a basement floor drain becomes the lowest exit point in your house. A floor drain that's already partly blocked with sediment or laundry lint makes a backup worse. Keeping that drain clear and confirming it flows freely before storm season is a simple step most homeowners skip.
Access is the last piece. Many older Detroit homes lack an exterior clean-out, so a plumber has to pull a toilet or work through a basement floor drain to reach the main line. We fix that by installing a sewer clean-out, so every future Detroit drain cleaning visit is faster and less disruptive. Our plumbers work across the city and neighboring communities like River Rouge, Dearborn, and Hamtramck every day, and they know which houses on which blocks tend to have which pipes.
