Serving Bayside Since 1981
Wooded Lots and Wet Ground
Bayside sits at the northern edge of the North Shore, stretching into Ozaukee County. Many homes were built from the 1950s through the 1970s on generous wooded lots, and a lot of them sit near ravines or slopes that funnel water toward the house.
Those mid-century foundations are often poured or block walls with drainage systems that are now 50 or more years old. When that drainage starts to fail, the first signs are usually damp spots, seepage at the floor line and a sump pump that just can't keep up.
We'll trace where the water is coming from, inside and out, and recommend the fix that fits your home and your lot.

What We See in Bayside
Common Basement Problems in Bayside Homes

Wet lots keep sump pumps running hard, and older pumps wear out without warning.

Aging drainage lets groundwater push up through the floor-wall joint.

Shrinkage and soil pressure leave cracks that can leak in heavy rain.

How We Help Bayside Homeowners
Sump PumpsSump Pumps & Battery Backups
In Bayside, a dependable sump pump is essential. We install pumps sized for how much water your lot actually handles, with sealed pits and check valves.
A battery backup keeps the water moving during power outages, when you need it most.
We test the system before we leave and walk you through how it works, so you know your Bayside basement is protected the next time a storm rolls through.

SeepageFloor & Wall Seepage
Seepage along the base of the walls means pressure is building under the floor. New interior drain tile relieves it and carries the water to your sump.
It's installed from inside, so your wooded yard stays untouched.
Because the fix relieves the pressure instead of just sealing the surface, the water doesn't simply move to a new spot. Most Bayside homeowners notice the difference after the very next storm.
Seepage Solutions
CracksFoundation Crack Repair
Cracks in mid-century poured walls are common. Leaking cracks are sealed from inside with injection.
If a crack is getting wider, we'll check the wall for movement.
Every crack repair starts with measuring and documenting what we see, so you'll know whether it's a one-time fix or part of a bigger issue in your Bayside home.

ExteriorExterior Waterproofing
When water is coming through several walls, exterior waterproofing stops it at the source.
We excavate, seal the wall, add drainage and restore the area.
It's a bigger project than interior work, but for the right Bayside home it's the most complete protection you can get.

Bayside Questions
Bayside Basement FAQs
Why does my sump pump run so much?
Wet, sloped lots send a lot of groundwater to the pit. Constant running in dry weather may mean a stuck float or small pit.
Do you serve the Ozaukee County side of Bayside?
Yes. We serve all of Bayside.
Is interior drain tile right for my home?
For most seepage, yes. It relieves pressure under the floor without disturbing your yard.
How long do sump pumps last?
It depends on how often they run. Old or noisy pumps should be replaced before they fail.
Can you seal a leaking crack from inside?
Yes. Leaking cracks in poured walls are usually injected from inside.
