Drain Problems We Clear Every Day

Common Drain Issues

From simple clogs to complex sewer line blockages, we've seen it all and fixed it all.

Slow or Clogged Kitchen Drains

Grease, food particles, and soap buildup are the most common culprits. We clear the blockage and help prevent future buildup.

Backed-Up Bathroom Drains

Hair, soap scum, and toothpaste create stubborn clogs in shower, tub, and sink drains that require professional clearing.

Toilet Clogs & Overflows

When a plunger won't cut it, our technicians use professional-grade augers and cameras to locate and clear deep trap and line blockages.

Main Line Blockages

When multiple drains back up at once, the problem is usually in your main sewer line. We diagnose and clear root intrusion, debris, and collapsed sections.

Recurring Clogs

Clogs that keep coming back often indicate root intrusion, bellied pipes, or buildup that needs hydro-jetting to fully resolve.

We had both our water heaters go out on the same day. M&M came out immediately to inspect situation and got us scheduled for earliest replacement. The team was professional, communicated well and updated me on the process. We went with the tankless heater and couldn’t be more pleased. I highly recommend them!

Jim, their master plumber, came out to look at the shower valve that needed replacement and write up a quote. He came across as knowledgeable and trustworthy and gave a much more reasonable estimate than other companies. He came on time and their company scheduling system worked well. Blake came out to do the shower valve replacement soon after and was also excellent. Glad to have a company that I can use again for any future issues.

There’s no experience quite like having your furnace call it quits during winter, but because of companies like M & M Heating, cooling, and plumbing this problem was examined, addressed, and fixed all in 24 hrs! From the first inspection and diagnosis with Cody to meeting Tanner and Matt the next day with my new furnace for installation, all the customer service was top notch! They were all calm and respectful and very informative. I would highly recommend this company to any in Noco!

Your Drain Cleaning Questions Answered

How quickly can you clear a clogged drain?

We offer same-day and emergency service for urgent drain issues. Most standard clogs are cleared within an hour of arrival. More complex main line issues or those requiring hydro-jetting may take longer, but we'll always give you a clear time estimate upfront.

Is there an extra charge for emergency or after-hours service?

No. M&M never charges extra for nights, weekends, or emergency calls. The price we quote is the price you pay, period.

What is hydro-jetting and do I need it?

Hydro-jetting uses high-pressure water to scour the inside of your pipes clean. It's ideal for recurring clogs, heavy grease or scale buildup, root intrusion, and as a preventive maintenance measure. Our technician will recommend it only when it's the right solution for your situation.

How can I prevent drain clogs?

Avoid pouring grease or oil down the drain, use drain screens to catch hair and food particles, run hot water after each use, and schedule annual professional drain cleaning — especially for older homes with mature tree roots near sewer lines.

Do you offer sewer camera inspections?

Yes. We use state-of-the-art sewer cameras to inspect your lines and identify problems like root intrusion, buildup, cracks, or collapsed pipes. This helps us recommend the most cost-effective solution and avoid unnecessary work.
