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.

M & M has been my go-to HVAC company since 2021, when they helped us choose and install a new furnace along with a complete heating and air conditioning system. The entire process was easy, and the new system made our home much more comfortable. Since then, they’ve been the only company I recommend to friends and family whenever they need heating, cooling work. It’s hard to find a company that’s consistently reliable, but M & M has always delivered. Their team is always prompt, communicates well, and keeps me updated by text/email throughout appointments, which I really appreciate. It’s the little things like that, combined with the quality of their work, that make them stand out. If you’re looking for an honest, dependable HVAC company that genuinely takes care of its customers I highly recommend M & M.

Highly recommend M&M. I used them for both plumbing and electrical and experienced great customer service. The front desk was easy to work with for scheduling and payments. My plumbing technician David T. was excellent, communicating with me throughout the entire process and giving me the ability to weigh in on decisions that needed to be made. My electrical technician was Joey and he was fantastic. Extremely knowledgeable, easy to communicate with, and also continued to communicate throughout the entire job to make sure I was being included in decisions and able to give clarification when needed to make sure everything I needed done was being done. I could not recommend David and Joey highly enough!

I had a great experience with M and M! I really appreciate that they called ahead with their ETA as they were ahead of schedule! Joe was professional, friendly and very knowledgeable. He took the time to explain everything he found and answered all of my questions without making me feel pressured. I also loved that they included photos to support their recommendations and emailed a detailed report afterward with transparent pricing for any maintenance or repairs. It made it easy to understand the condition of my system and make informed decisions. Excellent communication, honest service and a very professional experience. I highly recommend M and M!

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.
