Drain Cleaning Service in Bethesda
A sink that drains slowly and a basement floor drain that backs up need different investigations. Tell the plumber which fixtures are affected, when the problem returns and whether another fixture makes the water rise. That helps distinguish a local trap or branch blockage from trouble farther down the building drain.
Many older Bethesda homes have been remodeled around plumbing that predates the latest kitchen or bathroom. A new fixture does not establish the condition of the drain behind it. We assess the accessible pipe and its material before choosing a cleaning method, rather than assuming every line can tolerate the same equipment.

A camera goes down the main line before recommending work. You see what we found.
Cabling or jetting chosen against the clog's composition — grease, hair and roots are not the same job.
Bio-Clean for maintenance — natural bacteria and enzymes, not something that attacks the pipe.
Worth Knowing
Mature trees and older sewer laterals are part of the local context recorded in Mallick's Bethesda service-area information. Roots are one possibility, not a diagnosis we make from a street name. Where recurring main-line symptoms call for it, camera inspection can help identify intrusion, damaged joints or a restriction that opening the drain alone will not resolve.
Access matters as much as the equipment. Let us know where the cleanout is, whether a previous plumber left inspection footage and whether the blockage has already been treated. Those details help plan the visit and avoid repeating an approach that has only provided temporary relief.
Response protocol
Cleaning restores a flow path through accumulated material. Inspection investigates what the line looks like, and repair addresses a physical defect. We explain which step the findings support. Hydro jetting is an option for suitable pipes and conditions; it is not a substitute for replacing a collapsed or disconnected section.
For a single clogged fixture, the first step may stay close to that fixture. For several slow drains or a recurring backup, the assessment reaches the shared line. You can read the full drain-cleaning and camera-inspection guides through the related-service links below without losing the Bethesda booking route.
Share the Bethesda service address, affected fixtures and the history of the issue. Tell the office about active leaks or backups and any access restrictions. Emergency requests must be made by phone so dispatch can respond to the situation.
The plumber checks the affected drain, accessible pipe and the pattern of the blockage. Cleaning, camera inspection and repair have different purposes. We explain the supported next step and confirm any authority or utility involvement if the work extends beyond routine clearing.
The team carries out the agreed service and checks the result. Ask what was found, what was done and what to watch for afterward. Keep any inspection findings and service details so a future visit can build on the actual history of the system.
Worth Knowing
Avoid adding chemical drain cleaner while a backup is being assessed, and tell the technician if a product has already been used. If wastewater is rising, stop using affected fixtures and keep people away from contaminated water. Call for urgent help rather than continuing to test the drain by running more water.
Mallick serves Bethesda from its Maryland operation. Call the office or use Schedule Service for planned drain work; emergency requests go through the phone line. Have the property address, affected fixtures and any prior cleaning or repair details ready so the team can understand the problem before the visit.

“Eric and Nick did a wonderful job.”
Very thorough and provided detailed explanation of what was needed to get our garbage disposal up and running.
Abbas and Koli were great technicians.
Quickly diagnosed the issue, thoroughly explained everything, and gave me a few options to move forward. I've had great experiences working with Mallick, highly recommend.
Abbas came to our house for an emergency repair on a Saturday.
He was courteous and kind, he didn’t rush, and he worked hard to fix our problem and thoroughly investigate. It was hard to find a plumber who could do this on a Saturday at the last minute, and we appreciated Mallick’s and Abbas’s willingness.
Abbas Rahimiari was exceptionally professional, looking at our two plumbing problems, describing the underlying issues, fixing one immediately and explaining options on the other. Courteous, clear and efficient. And knowledgeable.
I had a wonderful experience with Billy.
He was amazing and he was able to fix my issue with no concerns! 10/10! Thank you Billy.
Excellent service and support from William Clem and Malick Plumbing.
Had a pinhole leak in a water service line. Found and fixed the problem … thanks so much.
Roberto and Adelson were great to work with, efficient, and answered all questions. Top service and repair of water heater!
Fred and Luka were great!
They took the time to find the issue as well as helping me get opinions on future concerns as a new homeowner! Real experts and will work with them again!
Abbas and Koli were fantastic.
They quickly identified and resolved our issue, and did a check to ensure there were no other sleeping issues. They were a pleasure to work with, respectful, and kind.
I received great service from both Ikem and CJ today.
They quickly identified the leak and fixed the issue. They also did a great job replacing some valves that needed replacing. They were very experienced and efficient. I have used Mallick several times and have always been pleased with their service.
Abbas and Erick were professional, knowledgeable and kind.
They inspected and guided me to make safe choices with my range that had a gas leak.
Abbas and Bryan installed my new water heater.
There was a leak in my furnace and they fixed it also! The job was perfect. They had to install vents that were well done. They left no trace and the house was completely clean. The new water heater works like a charm. HIGHLY RECOMMEND this team and Mallick.
Kyle was so helpful in helping my husband and I fix the water pressure in our house. Kyle was very well versed and experienced, providing great options for future improvements to water filtering. I would highly recommend his services to anybody struggling with plumbing issues.

(301) 804-6759Someone picks up 24/7 — nights, weekends, and holidays included.
No. Roots, buildup, a damaged section and other restrictions can produce similar symptoms. The history of the backup and, when appropriate, camera inspection help distinguish them. Mature trees nearby are a reason to investigate, not proof that roots are in the pipe.
Yes. Tell us about previous renovations, repairs and any known pipe material. The plumber checks the accessible system and chooses an approach suited to its condition. Fragile or damaged pipe may need a repair plan rather than a more forceful cleaning attempt.
Clearing an existing drain and altering a sewer or plumbing installation are different scopes. If the findings call for permitted work, we confirm the requirements for the address and explain the inspection path before proceeding. Bethesda plumbing work on WSSC systems follows WSSC requirements.
