Sewer & Drain Service in Denville, NJ

Denville's lakeside neighborhoods and the Rockaway River make sump pumps and basement flood prevention a year-round concern. FlowMaster Sewer Services provides 24/7 sewer and drain service throughout Denville, Morris County, and the surrounding communities of Parsippany, Rockaway and Boonton. Based minutes away in Cedar Grove, our fully-equipped trucks reach Denville quickly, and we never add a surcharge for nights, weekends, or holidays. Because many homes here were built in the mid-20th century, an era of clay and early cast-iron sewer lines that are now reaching the age where roots and cracks become common, local sewer problems here have a recognizable pattern, and we bring the equipment and experience to fix them right the first time.

⚠️ Developer note: these are sample testimonials. Connect the Google Business Profile review feed before launch.

Our basement started backing up at 11pm and FlowMaster had someone here within the hour. No crazy after-hours charge like the big companies wanted. Cleared the main line and showed us on camera what caused it.
Sample, Maria D. · Clifton, NJ
Had them camera the line before we bought our house. Found root intrusion the home inspector completely missed, saved us from a huge surprise. Professional and honest.
Sample, James R. · Montclair, NJ
Recurring kitchen drain clog that two other plumbers just snaked. FlowMaster hydro-jetted it and it's been perfect since. Wish I'd called them first.
Sample, Anthony P. · Wayne, NJ
