Sump pump repair in Mundelein, IL when the basement floods
A sump pump sits in a pit and moves groundwater away from the foundation. When it fails during a storm or thaw, water can reach the floor in minutes. Failures include a stuck float, a burned motor, a clogged intake, a failed check valve or a power outage.
Our 24/7 line sends a licensed plumber who restores pumping first, then tests the system and discusses a backup. We install new pumps, battery backups and discharge lines.
If water is rising in the basement
Do not step into standing water if outlets, the furnace or the electrical panel may be wet. Switch off power at the breaker only if you can reach it dry. Check that the pump is plugged in and the breaker has not tripped. Pour a bucket of water into the pit to see if it starts. Call the 24/7 line if it does not.
Common sump pump problems
- A pump that hums but does not pump, often a seized motor or a clogged impeller.
- A float stuck against the pit wall so the pump never turns on.
- A pump that runs constantly because the check valve has failed or the pit is undersized.
- A discharge line that is frozen, disconnected or draining next to the foundation.
- A power outage during the storm, with no backup in place.

Why Lake County basements get wet
Lake County has areas of high groundwater, and neighborhoods near Diamond Lake and Countryside Lake sit close to water bodies. Spring thaw and heavy rain raise the water table and send water toward foundation walls. A pump with a battery backup is practical here, because storms and outages often happen together.
If your pump is working but the basement still seeps, the problem may be at the walls or floor, which our basement waterproofing page covers. Pumps tied to a floor drain should be checked along with drain cleaning.

What affects sump pump pricing
The unit and the pit define the cost, and we quote before starting.
- Pump type. Primary and backup pumps differ widely.
- Pit condition. A cracked pit may need replacement.
- Discharge piping. Longer or buried lines add work.
- Electrical. A dedicated outlet or GFCI may be needed.
- Hour. Emergency dispatch is priced separately.
Water backup coverage is typically a separate endorsement on a homeowners policy. Check yours.

The discharge line and winter
A pump can run perfectly and still fail if the discharge line is frozen, kinked or sending water back toward the house. In winter, keep the outlet clear of snow and ice and make sure the line slopes away from the foundation. A buried line that drains downhill avoids freezing.
Standards for sump systems
Sump piping and check valves follow the Illinois Plumbing Code, the state standard (Title 77, Part 890 of the Illinois Administrative Code) and the pump maker's instructions. Where the discharge goes is a local drainage question, so ask the Mundelein building office at 847-949-3283 before changing it.
What to do before we arrive at a flooded basement
Safety comes first when the pump has failed.
- Do not enter standing water if outlets or the panel are wet.
- Switch off basement power from a dry location.
- Unplug the pump only if the floor around the outlet is dry.
- Move belongings off the floor and open the pit lid to see whether the float is stuck.
- Call (847) 281-8626 and tell us the water depth.
Sump pump questions
Yes. The 24/7 line sends a licensed plumber when a pump fails and water is rising.
Test it a few times a year and before storm season by pouring water into the pit.
If your basement has flooded or you have finished space below grade, a backup is worth considering.
Away from the foundation and in line with local rules. Ask Mundelein Public Works at 847-949-3270.
It can happen in wet weather, but constant running in dry weather points to a stuck float or a failed check valve.
Plumbers can install a pit and pump. If the cause is a foundation crack, a waterproofing contractor may also be needed.
