Serving Mequon Since 1981
Newer Homes Still Need Dry Basements
Much of Mequon was built from the 1970s on, with larger homes on bigger lots and plenty of finished lower levels. Newer construction usually means poured concrete walls, but even poured walls crack, and tie-rod holes and cracks can leak once the ground is saturated.
Mequon's heavy clay, low areas and stretches near the Milwaukee River keep the ground wet in spring. That puts steady pressure on basements and a lot of work on sump pumps.
We'll show you exactly where water is getting in and recommend the right repair for your home, from a single crack to a full drainage system.

Common Basement Problems in Mequon Homes
Poured walls crack as they cure, and tie-rod holes can leak in wet seasons.
Wet springs keep pumps running constantly, and they wear out.
Leaks behind drywall often go unnoticed until flooring or trim is damaged.

How We Help Mequon Homeowners
Wall LeaksLeaking Walls
Leaking cracks and tie-rods in Mequon's poured walls are usually sealed from inside with injection.
We fill the crack through the full thickness of the wall so water can't simply go around the patch.
We'll show you exactly where the water is getting through and explain why we're recommending one repair over another, so there are no surprises on your Mequon project.
Wall Leak RepairSump PumpsSump Pumps & Battery Backups
With wet springs and heavy clay, a dependable sump system matters. We install properly sized pumps and battery backups.
For very wet lots, a second pump adds capacity.
We test the system before we leave and walk you through how it works, so you know your Mequon basement is protected the next time a storm rolls through.

SeepageFloor & Wall Seepage
Seepage at the floor line in finished basements is handled with interior drain tile that relieves the pressure.
We open only a narrow strip along the walls and patch it when we're done.
Because the fix relieves the pressure instead of just sealing the surface, the water doesn't simply move to a new spot. Most Mequon homeowners notice the difference after the very next storm.

ExteriorExterior Waterproofing
For homes where you'd rather not open finished space, exterior waterproofing stops water before it reaches the wall.
We excavate, seal and add drainage, then restore the yard.
It's a bigger project than interior work, but for the right Mequon home it's the most complete protection you can get.

Mequon Questions
Mequon Basement FAQs
Can newer poured walls really leak?
Yes. Shrinkage cracks and tie-rod holes can leak once the soil is saturated.
Do you serve all of Mequon?
Yes, every part of the city.
Can you fix leaks without tearing up my finished basement?
Often. Crack injection is done from inside with minimal disruption, and exterior waterproofing avoids the inside entirely.
What are the metal pieces in my wall?
Tie-rods from the concrete forms. Their seals can fail and leak.
Do I need a battery backup?
For finished basements, we strongly recommend one.
