We're a family-owned plumbing company built on honest work, fair pricing, and showing up when we say we will. No franchises, no call centers — just local technicians who know Maryland's pipes.
Dave Kowalski started Maryland Sewer & Drain Pros in 2009 with one truck and a simple idea: do the job right, charge a fair price, and answer the phone. Word spread fast.
Today we run a team of eight licensed technicians serving eight Maryland counties. We've grown entirely through referrals — no paid ads, no gimmicks. Every job we take is a chance to earn the next one.
We're not the biggest company in the state. We're the one your neighbor calls when the big guys let them down.
We give you a two-hour arrival window and call 30 minutes before we arrive. No all-day waits.
We diagnose before we quote. No upselling, no unnecessary work — just the repair that solves the problem.
We lay down drop cloths, wear boot covers indoors, and leave the work area cleaner than we found it.
All labor is backed by a 12-month workmanship warranty. If it fails, we come back — no charge.
Dave founded Maryland Sewer & Drain Pros in 2009 after 10 years working for a regional utility. He holds a Maryland Master Plumber license and personally oversees every major job.
Marcus has been with the company since 2013. He specializes in hydro jetting and camera inspection, and has cleared some of the most stubborn commercial blockages in the region.
Priya keeps the schedule running and makes sure every customer gets a follow-up call after service. She joined in 2017 and has streamlined response times by 40%.
