"Replaced our old sump pump and solved a big problem."
—Scott C. | Colorado HomeownerAli was very helpful and professional. He replaced our old sump pump and solved a big problem. He went over and above to address the discharge pipe outside our house.
A sump pump sits in a pit at the lowest point of your basement or crawlspace and pumps out water before it can flood your home. For Denver-area homes, that matters during:
Sudden summer thunderstorms and hail-driven downpours Spring snowmelt running off the foothills Rising groundwater and a high water table after wet stretches Rapid runoff on properties with poor grading or drainageWithout a working sump pump (or with one that fails during a storm), that water ends up in your basement — damaging flooring, drywall, belongings, and anything stored below grade, and creating conditions for mold. A dependable pump, ideally paired with a battery backup, is your first line of defense. If yours is more than 7–10 years old or you've never tested it, it's worth having checked before the next big storm.
A first-time installation usually costs more, since it may require plumbing modifications, an electrical upgrade, and excavation for the reservoir (sump pit). Replacing an existing pump is typically simpler and less expensive.
Sump pumps come in two types: submersible and pedestal. Submersible pumps sit inside the reservoir, handle water exposure, and are quieter, less clog-prone, and more space-efficient — which makes them more expensive to install. Pedestal pumps cost less but sit above the pit.
A pump's power depends on its motor. More horsepower costs more, but the right size depends on your home — our plumber can tell you whether you need a higher-powered pump.
Sump pumps typically connect to a home's electrical system, which means they may not function during a power outage. To ensure protection against water damage even without power, you can opt for a backup battery addition to your sump pump. This extra feature will increase your installation costs.
Many do. Homes with finished basements, below-grade living space, a high water table, or poor exterior drainage benefit most. Denver's sudden summer storms, hail-driven downpours, and spring snowmelt can push water toward and into a basement, and a sump pump removes it before it floods. Not every home needs one, but where basement flooding is a risk, it's strong protection.
A sump pump sits in a pit (the sump) at the lowest point of your basement or crawlspace. As water collects in the pit, a float switch turns the pump on, and it pumps the water out through a discharge pipe away from your home's foundation. When the water level drops, the pump shuts off automatically.
Watch for strange noises (grinding, rattling, or constant humming), the pump running constantly or cycling on and off rapidly, visible rust or corrosion, vibration, a pump that's more than 7–10 years old, or water in the pit that isn't being pumped out. Any of these means it's worth having it inspected before a storm tests it.
Test it a few times a year, and again before spring storm season. The simple test: slowly pour a bucket of water into the pit and confirm the pump turns on, pumps the water out, and shuts off on its own. If it doesn't, call a licensed plumber.
Yes. Basic maintenance includes testing it, clearing debris from the pit, checking the discharge pipe for clogs or freezing, and confirming the backup battery (if you have one) holds a charge. Regular upkeep helps your pump last and keeps it ready when you need it.
Most sump pumps last about 7 to 10 years, depending on how often they run and how well they're maintained. If yours is in that range or older, it's smart to plan a replacement before it fails during a storm.
