Exterior Waterproofing for Oconomowoc Lake homes

Oconomowoc Lake is a small village of large homes along the water. Many have big finished basements with walkouts that open toward the lake, and those lower levels are real living space: family rooms, guest suites, wine storage, home gyms. When water gets into a basement like that, it damages drywall, flooring and cabinetry fast. Owners here expect the fix to be done right and the crew to treat the property with care.

Walkout homes have a buried wall on the uphill side and an open wall facing the lake. The buried side takes the pressure from groundwater and runoff coming down the slope, while the lake keeps the water table high along the lower yard. Water that gets through the uphill wall usually shows up behind finished walls first, as a stain, a smell or swollen baseboard, long before anyone sees a puddle.

Exterior waterproofing is the best match for these homes because the work happens outside and the finished rooms stay intact. We dig to the footing, repair the wall, and seal it with a liquid waterproof membrane and dimple board. New weeping tile goes in with washed gravel, and we grade the backfill away from the house. Our crew protects landscaping, hardscape and the house, and cleans up daily. When the Village of Oconomowoc Lake requires a permit, we pull it.

What's Included

What exterior waterproofing in Oconomowoc Lake includes

For a finished lakefront basement in Oconomowoc Lake, our exterior waterproofing covers these four pieces from the outside:

Excavation to the footing

We dig along the leaking wall down to the footing so the whole face of the foundation can be cleaned, repaired and sealed.

Liquid waterproof membrane

Cracks get hydraulic cement, then the wall gets a thick elastomeric membrane that keeps water off the concrete.

Dimple board and weeping tile

Dimple board gives water a gap to drain down, and new perforated weeping tile at the footing carries it away.

Washed gravel and regrading

Washed gravel around the tile keeps it draining, then we backfill and grade the soil to slope away from the house.

What homeowners say about our crew

★★★★★

They replaced our drain tile, put in a sump pump, set steel beams, and sealed the basement walls - then redid the window wells and buried a downspout outside. The price was competitive and Nick, Luis and the crew explained everything as they went.

Questions, Answered

Oconomowoc Lake exterior waterproofing FAQs

That's the main reason to go exterior. We work from the yard side, so the finished rooms usually stay as they are. We'll confirm after the inspection.

It often is. Water through a buried wall shows up behind finishes before it reaches the floor. An inspection of the outside wall and grade tells us where it's coming from.

Very typical. The buried side takes the runoff and groundwater from the slope. That's usually the wall we dig, seal and drain.

We plan the dig around your hardscape and plantings before we start. Anything in the trench line is protected or set aside, and the site is cleaned up at the end of each day. Nick or Luis will walk it with you first.

It depends on the work. When the Village of Oconomowoc Lake requires a permit, we pull it. You won't have to manage it.

Yes, that's the right order. Sealing and draining the wall from outside before a remodel protects the new finishes. The lifetime warranty stays with the house.

We work that out on your lot during the inspection. The tile needs an outlet or a sump to send water to. We'll explain the plan in your written quote.

Exterior work happens outside, so that can often be arranged. We'll agree on access and keep you updated. You can walk the finished job with us when you're back.

It depends on how many walls need work. A single wall usually takes a few days, and larger homes take longer. The schedule will be in your written quote.

Yes. Our lifetime warranty transfers to the next owner. Buyers of lakefront homes tend to value that documentation.
