"We were very happy with the response and service. Frank & Sam came same-day to diagnose our problem. They diagnosed & cleared a clog in the drain line and cleaned our sump basin to remove the odor. Once the clog was cleared, they also ran the drain camera throughout the lines under the house to check the integrity of the pipes. They were professional, personable, and efficient. They cleaned up thoroughly after they were finished. We'd definitely hire them again."

"BFMD is the best sewer line cleaning service I have ever used. Several other contractors insisted that I needed a new sewer line and quoted very high prices. BFMD determined this was not necessary and was able to clear my line completely. Great job, great service, great professionalism, and great honesty."

"Supper job, this was a difficult job. I did not know what was wrong with the toilet clog, it flooded out two floors over 7000.00. I first called Roto Rooter the fix it for two days. We were referred to Monster Plumbing and he came fixed it and told me if I had any more problems to call him again. Two later again toilet clogged. He came out with a scope and found some type of wiring that the builders dropped in during our rebuild after a fire. Pulled it out and what a relief super job!!! He was very assertive that he would find the problem. GREAT JOB!!!"

"Sawma and his son came out in one hour on a holiday weekend and snaked our sewer main line for a very reasonable price. Sawma also figured out (in five minutes) what was causing our shower to leak after two other plumbers—including one from one of the big Maryland plumbing companies—charged us a ton of money but failed to solve the problem. He is a smart, honest, friendly plumber who makes a point of explaining what he's doing. I would definitely use BW Plumbing and Drain again."

Sewer Cleaning FAQs, answered by experts

You could be smelling sewer gas in your kitchen because of a dry P-trap, clogged vent pipe, or leaking plumbing seals. If you smell a rotten egg odor, check your sink’s P-trap and plumbing connections first. A clogged or damaged vent pipe can trap sewer gas and push it back into your kitchen through the plumbing pipes. Loose or deteriorated seals around drainpipes can also allow sewer gas to leak out. If you can’t find the source, call a local plumber for expert help.

Water leaking through your basement floor is a good sign of a clogged drain, but another sign of a clogged basement floor drain can include unpleasant odors coming from the drain. Also, hearing gurgling noises when water drains from the basement or having other plumbing fixtures (like toilets or other drains) backing up is a good indicator.

Cat pee has a strong ammonia-like smell, so if you smell cat pee but don’t have a cat or don’t suspect your cat has any accidents, there could be other issues at hand. Aside from pet urine, your house may smell like cat pee from leaking freon from an old fridge, mold, spilled cleaning supplies, or even outside odors from nearby farms.

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.

Outdoor plumbing issues are no less serious or urgent to fix than interior plumbing problems. These problems may require excavation and lawn repair due to the plumbing often being buried underground. The most common outside plumbing problems include:

  • Clogged landscape drainage: $200–$1,000

  • Clogged sewer lines: $60–$250 per linear foot

  • Corroded or rusted pipes: $1,500–$15,000+

  • Leaking drain lines: $200–$1,000

  • Leaking water mains: $300–$4,000+

  • Septic system failure: $600–$3,000+

  • Tree roots in pipes: $200–$1,000

  • Well pump failure: $350–$1,500
