What Causes Clogged Sinks and Drains?

Clogged sinks and drains are the most common service calls we receive, so you’re not alone. Drain clogs happen for many reasons and stoppages can occur anywhere, from the easily-accessible piping under sinks to further down the main drain lines.

How Do I Know if I Have a Drain Clog or a Main Line Stoppage?

If you notice water backing up in the lower drains in your home like your tub and shower drains, then you have a main-line stoppage. Main line stoppages are different than a simple drain clog because they occur in the horizontal sewer pipe that runs underneath your home. If you are experiencing water backing up in your home, visit our Sewer Stoppage & Repair page.

What Causes Drain Clogs in the Kitchen?

In the kitchen, food waste is the major culprit in clogged sinks. Sudden clogs often can be fixed by clearing the P-trap under the sink, but food particles and grease can also build up further along the line. This sludge can slow and finally clog kitchen sinks.

What Causes Drain Clogs in the Bathroom?

In bathrooms, hair and soap residue cause slow draining tubs and showers which, over time, can clog completely. And toilets are prone to a number of stoppages along the lines.

Often, drain clogs may cause backups that can result in water damage to the floors and walls of your home.  After the clog is resolved, the John Moore Home Renovation and Remodeling team can assist with any additional home repairs that may be needed, such as drywall / sheetrock repair or replacement and painting.

  • I was looking for Dave Smith and Brandon Jones in here and I do not see their names. They both worked very hard and I was impressed by their team work.It was efficient until Brandon had an emergency and left Dave to do a two man job alone for the rest of the 2nd day. Dave was really committed to getting the the bathroom up and running for me each night before they left. I was pleased with their kindness in answering questions that I had while they were doing the work. I would call them again though I hope I don't need to.

  • Had a clogged drain line in my upstairs bathroom. Called John Moore Services and made an appointment for the next day. Edwin G. was the Field Technician to come out to my home. I explained to him the problem and then he explained the options to me. I told him to go with the best option. Drain line was unclogged. He was very professional and very knowledgeable. He explained what he was going to do and also took pictures of the repairs once he was done. Overall it was a great experience and I have to give Edwin G. and the John Moore Services a 5-Star for a job well done. Couldn't ask for anything better, and will be using them in the future. Thank you Edwin G./John Moore Services.
