Why It Happens

Why McHenry Basements Flood

The source decides the fix:

Up Through the Floor Drain

Sewer water pushing back from a blocked line or an overloaded system.

Through Walls and Floor Cracks

High groundwater around the foundation, common near the river and lakes.

Through Window Wells

Surface water from heavy rain or a yard that slopes toward the house.

From a Pipe or Appliance

A burst pipe or a failed water heater. Shut off the water and call.

Local Knowledge

Basement Flooding in McHenry

In July 2017, the Fox River flooded and the state declared McHenry County a disaster area. Homes along the river and the Chain O'Lakes took on water.

You Don't Have to Live on the River

Heavy rain raises groundwater and loads the sewers, so homes away from the river can still get basement water in wet seasons.

Sump Pumps Under Strain

When groundwater stays high for weeks, sump pumps run nonstop. A failed pump is one of the most common causes of basement flooding here.

Finished Basements

If your basement is finished, water damage adds up fast.

Layered Protection

A strong sump pump with a battery backup, a backflow valve and, for repeat sewer backups, an overhead sewer system.

Waterproofing

Basement Waterproofing

Waterproofing keeps groundwater out of the basement. Our part is the plumbing that does the work: sump pits, pumps, battery backups, discharge lines and the drain tile that carries water to the pit.

If water comes in where the wall meets the floor, the drain tile may be clogged or the pump can't keep up with McHenry's high groundwater. We check the system and tell you what will actually stop it. For water coming up through drains, see sewage backup service.

"I had water backing up in the basement on a Sunday. I called them and he came an hour later. John figured out the problem quickly-ejector pump, and what to do if it happens again. I did get an estimate for a new one if it needs replacing."

Basement Flooding Questions From McHenry Homeowners

Stay safe, stop the water if you can and call.

Keep away from water near outlets or appliances. If a pipe or appliance is leaking, shut off the main. If water is coming up through the floor drain, stop using water. Then call us.

Groundwater rises with the river, and sewers carry more water.

When the Fox River and the lakes are high, groundwater rises too and sewer systems carry more water. A strong sump system and backflow protection handle both.

Yes.

Yes. If your backflow valve is stuck, leaking or failed during a backup, we can repair or replace it.

If the pump can't keep up, yes. If it's sewer water, no.

If groundwater is coming in faster than your pump can remove it, a bigger pump or a second one helps. If water comes up through drains, you need backflow protection instead.

It depends on the source and the fix. You get a flat price first.

It depends on where the water comes from and what it takes to stop it. We give you a flat-rate price for each option before any work begins.
