Professional, Well-Trained Technicians
Every technician is WSSC-licensed, certified by the Washington Suburban Sanitary Commission that runs water and sewer service across Montgomery and Prince George's County. We're proud members of the Plumbing-Heating-Cooling Contractors Association (PHCC), the Water Quality Association (WQA), Quality Service Contractors (QSC), and we're Maryland's only TOTO Factory-Trained Plumbing Company.
Background Checked, Verified on Arrival
Every technician is background checked before they ever step foot in your home. You'll get a photo of the team member on their way, and they'll arrive in a clearly marked, lettered Mallick vehicle, so you know exactly who's at your door before you open it. The person doing the work is a Mallick employee, not a subcontractor, and we walk you through your options before any work begins.
Emergency Service Available 24/7
Plumbing problems don't wait for business hours, so neither do we. Whether it's the middle of the night or a weekend, a real person answers the phone and a technician is on the way. No answering service, no waiting until Monday. We're here for you.
Warranties on Installations & Repairs
We offer a one-year warranty on installations and a 30-day warranty on repairs, in writing. Members receive extended warranty coverage as part of their membership.
Financing & Special Offers
Plumbing problems don't always work on a planned schedule, which is why we provide payment plans through GreenSky to arrange the service homeowners need.
