Sump Pump Repair in Longmont: Keep Your Basement Dry

A large share of Longmont houses have basements, finished or not, and many of them have a sump pit that collects groundwater from the drain tile around the foundation. Spring snowmelt and heavy summer storms raise that water quickly. If the pump fails at the wrong moment, the first sign is usually wet carpet.

Warning Signs Your Sump Pump Needs Attention

• The pump runs constantly, or cycles on and off every few seconds
• It hums but water level in the pit doesn't drop
• Loud grinding, rattling or clanking while it runs
• Water standing in the pit above the float with the pump silent
• Rust, a bad smell or visible damage on the pump or discharge pipe
• Damp spots along basement walls after a storm

What We Repair and Install

• Float switches: a stuck or tangled float is one of the most common failures and one of the simplest fixes.
• Check valves: a failed check valve lets water fall back into the pit, so the pump works twice as hard.
• Discharge lines: we clear blockages and reroute lines that freeze or dump water back against the foundation.
• Pump replacement: submersible and pedestal pumps matched to the inflow we measure at your pit.
• Battery backup pumps: a second pump that keeps running when a storm knocks the power out.

Sump Pits, Radon Systems and Discharge Rules

Radon is common across the Colorado Front Range, and many radon mitigation systems draw from a sealed sump pit. When we service a pump in one of those pits we reseal the lid so the radon system keeps working. Sump water should discharge to the yard, away from the foundation, not into a floor drain or laundry sink that empties into the sanitary sewer.

Winter Care

Discharge pipes that run across the lawn can freeze solid in a Longmont cold snap, which leaves the pump pushing against ice. A freeze-resistant discharge fitting near the house lets water escape even when the outside line is blocked. If your basement has already flooded, see our emergency plumbing service.
