Drain Cleaning Service in Gaithersburg
Commercial drain cleaning in Gaithersburg
Commercial drain lines carry far more, and far worse, than residential ones. A restaurant or food-preparation business puts grease, food solids and volume through the same pipework all day, and clogs build at several points along the line rather than at one.
Mallick handles commercial drain cleaning in Gaithersburg for jobs of any size — restaurants, food service, multi-tenant buildings and industrial units.
Schedule Drain Cleaning Service
Tell us what you need — we’ll be in touch fast.
Line, Not Symptom
The whole line cleared, not the one point that restored flow.
Before, Not During
Scheduled intervals for food service, so it happens before service rather than during.
Commercial drains slowing during service? Residue is why it comes back.
Call (301) 804-6759Worth Knowing
Why diagnosis comes first
Chemical cleaners and plungers may not address the cause of a commercial blockage. We assess the line and choose an appropriate method.
Residue is why the clog comes back. The channel opens, the business carries on, and the same line blocks again in a fortnight — except now it is during service rather than before it.
Project control
How a commercial drain call runs
Not all clogs are the same and they should not be treated the same. A shower or washroom drain is usually hair; a kitchen line is food waste and grease; a floor drain in a production area is something else again.
So the method is matched to the blockage. Hydro jetting fires high-pressure water down the line and scours the wall, which is what heavy grease actually needs. Mechanical drain openers use rotating heads where a solid obstruction has to be cut. Using the wrong one is how a line gets cleared twice.
What is affected
We establish which fixtures and operations are affected before planning the response.
Blockage identified
The blockage identified before the method is chosen — grease, solids and hair each need a different tool.
Cleared along the line
Jetted or mechanically cleared along the line rather than at one point, since commercial clogs build in several.
Put on a cycle
A maintenance interval proposed where the property warrants it, so the next one is scheduled rather than urgent.
Worth Knowing
For food service this is maintenance, not repair
For food service, drain cleaning is not a repair, it is a maintenance interval — the line will need attention on a predictable cycle because of what goes through it every day.
Scheduled cleaning addresses recurring buildup and creates opportunities to inspect the grease trap and line.

“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.

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.
Chrissie Schenkel · Gaithersburg, MD 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.

Andrea Huerta · Gaithersburg, MD 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.

Why not just use a chemical drain cleaner?
They take a generic approach to a specific blockage and leave residue in the line. The channel opens, the business carries on, and the same drain blocks again within weeks — usually during service rather than before it.
What is the difference between jetting and mechanical cleaning?
Hydro jetting uses high-pressure water to scour the pipe wall, which is what heavy grease and scale need. Mechanical drain openers use rotating heads to cut through a solid obstruction. We choose based on what is actually in the line, because the wrong method means clearing it twice.
Should I schedule preventative drain cleaning or camera inspections?
Preventative cleaning and camera inspections can be useful for businesses with recurring clogs, heavy kitchen use or an uncertain drain-line history. Cleaning addresses buildup; a camera inspection helps show the condition of the line and potential causes of repeat problems. We can recommend an interval based on your building, use and inspection findings, then schedule the work around business hours where possible.
Can clogs build in more than one place?
Yes. Commercial clogs frequently build at several points along a line rather than at one, which is part of why a single-point clearance does not hold. We clear the line rather than the symptom.
