Expert Plumbing for Your Remodel

Plumbing is the backbone of any kitchen or bathroom remodel. Whether you're moving a sink, adding a second bathroom, or gutting the whole space, getting the plumbing right from the start saves you time, money, and headaches down the road. Poorly planned plumbing can delay your project, fail inspections, and lead to costly rework.

M&M Heating, Cooling, Plumbing & Electrical coordinates directly with your general contractor to keep your remodel on schedule. We handle all rough-in and finish plumbing, pull the necessary permits, and ensure every connection meets current building codes. For nearly 30 years, Front Range homeowners and contractors have counted on us to deliver quality plumbing work that passes inspection the first time.

The M&M Family
From Planning to Final Inspection

Our 4-Step Process

Professional remodel plumbing, done right from start to finish.

1

Consultation & Planning

We visit your home to assess the existing plumbing, review your remodel plans, and discuss layout options. Our plumber coordinates with your contractor or designer to identify the best approach for supply lines, drains, and venting.

2

Design & Estimate

Based on the consultation, we provide a detailed, written estimate covering all rough-in and finish work. We identify any permits required, flag potential code issues, and map out a timeline that fits your project schedule.

3

Professional Installation

Our licensed plumbers complete the rough-in plumbing — supply lines, drain lines, and vent stacks — before drywall goes up. Once walls are closed, we return for finish work: fixture installation, connections, and final testing.

4

Final Inspection

We pressure-test every connection, check for leaks, and verify proper drainage. We coordinate with the local building inspector to ensure your plumbing passes code review, and we don't leave until you're completely satisfied.

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 Remodeling Plumbing Questions Answered

Do you work with my general contractor?

Absolutely. We coordinate directly with your general contractor, designer, or builder to stay aligned on the project timeline. We schedule our rough-in and finish work around other trades so there are no delays. Clear, proactive communication is a core part of how we operate on remodel projects.

Do you handle plumbing permits?

Yes. We pull all required plumbing permits for your remodel and schedule the necessary inspections with the local building department. Permit requirements vary by municipality, but our team knows the codes for Longmont, Erie, Frederick, and every community we serve. You can rest assured your project will be done to code.

How long does remodel plumbing take?

Timelines depend on the scope of your project. A straightforward bathroom remodel with no pipe relocation might require one day for rough-in and another for finish work. A full kitchen remodel with relocated plumbing, or a basement finish with new drain lines, typically takes two to four days spread across the phases of construction. We'll provide a clear timeline during your consultation.

Can you relocate pipes for a new layout?

Yes. Pipe rerouting and relocation is one of the most common parts of remodel plumbing. Whether you're moving a kitchen sink to an island, shifting a shower to the opposite wall, or adding plumbing to a room that didn't have it before, we reroute supply lines, drain lines, and vent stacks to match your new floor plan while maintaining proper flow and code compliance.

What is the difference between rough-in and finish plumbing?

Rough-in plumbing is the first phase — it happens before drywall goes up. This includes running supply lines, drain pipes, and vent stacks inside walls, floors, and ceilings. It must pass a pressure test and building inspection before walls are closed. Finish plumbing is the final phase — it happens after painting and flooring are complete. This includes installing faucets, toilets, showerheads, sinks, and connecting appliances like dishwashers and disposals.
