Sump Pump Repair
& Installation
Expert sump pump installation, repair, and maintenance to keep your basement dry and your home protected. Same-day service from your trusted Colorado plumbing team.
Protect Your Home from Basement Flooding
A working sump pump is your home's first line of defense against basement flooding, water damage, and mold growth. Colorado's heavy spring rains, rapid snowmelt, and high water tables can overwhelm a home without proper protection — and a failed sump pump can mean thousands of dollars in damage.
For nearly 30 years, M&M Heating, Cooling, Plumbing & Electrical has helped Longmont and Front Range homeowners stay dry with expert sump pump installation, repair, and maintenance. Whether you need a new system, a battery backup, or a quick repair, we'll get it done right the first time.
Common Sump Pump Issues
From pump failures to backup power problems, we've seen it all and fixed it all.
Sump Pump Failure
A pump that won't turn on when water rises is the most common — and most costly — issue. We diagnose and repair or replace failed pumps quickly to protect your home.
Strange Noises
Grinding, rattling, or humming sounds often indicate a damaged impeller, worn bearings, or debris in the pit. Early diagnosis prevents complete pump failure.
Pump Running Constantly
A sump pump that cycles nonstop may have a stuck float switch, an undersized pump, or a check valve problem. Continuous running burns out motors and drives up energy costs.
No Power or Battery Backup
Power outages during storms are exactly when you need your pump most. We install battery backup systems so your sump pump keeps working when the power goes out.
Improper Installation
An incorrectly sized or poorly installed sump pump can't keep up with water flow, leading to flooding. We evaluate and correct faulty installations to give you reliable protection.

Your Sump Pump Questions Answered
How long does a sump pump last?
Most sump pumps last between 7 and 10 years with proper maintenance. Factors like usage frequency, water volume, and whether the pump has a battery backup can all affect its lifespan. If your pump is approaching 10 years old, we recommend having it inspected to catch potential problems before they lead to flooding.
Do I need a battery backup for my sump pump?
We strongly recommend a battery backup for every sump pump system. Power outages often occur during severe storms — exactly when your pump needs to be running. A battery backup ensures your pump continues operating even when the power goes out, providing crucial protection when you need it most.
What are the signs my sump pump is failing?
Watch for these warning signs: unusual noises (grinding, rattling, or humming), the pump running constantly or cycling too frequently, visible rust or corrosion, water in the basement despite the pump running, or the pump failing to turn on when the pit fills. If you notice any of these, call us for an inspection before a small problem becomes a big one.
How often should I have my sump pump serviced?
We recommend having your sump pump professionally inspected at least once a year, ideally in the spring before Colorado's heavy rain and snowmelt season. Annual maintenance includes testing the pump, checking the float switch, inspecting the discharge line, and verifying the battery backup — all of which help extend the life of your system and prevent unexpected failures.
How much does sump pump installation or repair cost?
The cost depends on the type of pump, whether you need a new installation or a repair, and whether you'd like a battery backup system. We provide upfront pricing before any work begins — no hidden fees, no surprises. Give us a call or schedule a free inspection and we'll provide an honest quote tailored to your home's needs.
