Serving Fontana's Lakefront, Bluffs and Wooded Neighborhoods
Fontana-on-Geneva Lake is a village at the west end of Geneva Lake in Walworth County. Its homes range from lakefront estates and historic cottages to houses tucked into the wooded hillsides and bluffs above the water.
Building on Fontana's slopes means foundations work as retaining walls. Uphill walls hold back soil and the water that runs down through it, lakefront homes face high groundwater and older cottages may sit on stone or block foundations never designed for year-round use.
We bring crews from Hales Corners to Fontana and plan every job around the realities of building on a bluff. You'll get a clear written proposal before anything starts.

Foundation & Basement Services in Fontana, WI
Fontana Foundation Crack Repair
Fontana's sloped lots put uneven loads on foundations. Cracks often form on uphill walls and where wall heights change. Older cottages crack along mortar joints, and newer homes show vertical shrinkage cracks.
We look for horizontal cracks on uphill walls, cracks at height transitions and any crack bringing in water.
We study each crack in the context of the slope it sits on, checking for movement and moisture, and explain whether it needs sealing, reinforcement or a change in how water reaches the wall.
- Uphill wall cracks
- Height-transition cracks
- Older cottage foundations
- Leaking cracks
Bowing Basement Walls in Fontana
A Fontana home built into a bluff has a basement that holds back the hillside. The soil on that uphill side stays wet after storms and freezes hard in winter, and that combined pressure is what pushes walls inward.
Bowing on these lots usually starts on the uphill wall with a long horizontal crack. As it progresses, the wall leans in at the top and blocks near the corners begin to step out of line.
We measure the movement and recommend steel bracing for walls that can be held in place, or excavation, straightening and exterior waterproofing when access on the bluff allows it.
- Bluff-side pressure
- Clay and frost
- Shifted blocks
- Bracing or straightening
Settling Foundation Repair in Fontana
Fill on the downhill side of Fontana's sloped lots can settle over time, and older cottages may have additions on shallow footings.
Watch for floors sloping downhill, sticking doors, diagonal cracks and porches or decks pulling away.
We pinpoint whether the problem is fill, runoff under the house or a shallow footing, and recommend a repair that holds the house steady on its slope.
- Downhill fill
- Cottage additions
- Floors sloping downhill
- Separating porches

Wet Basement Repair in Fontana, WI
In Fontana, water comes from two directions: runoff down the bluffs and groundwater near the lake.
On Fontana's bluffs, water usually shows up on the uphill side first, at the base of the buried wall or across a walkout floor. Near the shoreline, it can rise from below. Watch for damp carpet, white residue and musty air.
We determine whether the water is coming down the hill, up from the lake or through clogged drainage, and recommend the matching fix: surface drainage and swales, an interior drainage system with sump or exterior waterproofing on the uphill wall.
- Bluff runoff
- Lake groundwater
- Damp walkout floors
- Efflorescence
Leaking Basement Walls in Fontana
Uphill basement walls in Fontana take the brunt of storm runoff. Water builds in the soil behind them and finds its way through shrinkage cracks, form-tie holes and the hollow cores of block.
Look for dampness that appears a day after rain, rust-colored marks below small round holes, bubbling paint and white mineral crust on the uphill wall.
Isolated cracks in poured walls are usually injected. Block walls and walls that are wet along their full length typically need interior drainage or exterior waterproofing to stay dry.
- Uphill leaks
- Streaks below cracks
- Mineral deposits
- Uphill waterproofing
Floor & Wall Seepage in Fontana
Runoff that soaks into Fontana's slopes can travel under the house and collect beneath the slab, then rise through the joint at the edge of the floor during thaw.
Walkout owners often first notice a darker strip of concrete along the buried wall or water spreading toward the patio door after snowmelt.
We install perforated drain pipe along the footing on the uphill side and beyond, carrying the water to a sump before it reaches the floor.
- Snowmelt seepage
- Damp buried-wall strip
- Water across walkouts
- Interior drain tile
Drain Tile Systems for Fontana Homes
Many Fontana homes drain footing tile to outlets on the downhill side, and those outlets can clog with roots and silt. Older cottages may have no drainage at all.
When those outlets fail, water backs up against the uphill wall and leaks return after every significant storm.
We clear, repair or replace the drain lines and outlets, or connect the system to a sump when a gravity outlet isn't practical.
- Clogged downhill outlets
- Cottages without drainage
- Repeat storm leaks
- Sized for your lot
Sump Pump Installation in Fontana
Many Fontana homes are seasonal, and a sump pump failure while no one's there can mean serious water damage.
If your pump is older, cycling constantly or has never been tested, it's worth checking before you leave for the season.
We install pumps matched to your home's water and add a battery backup that switches on automatically, with alarm options for owners who are away.
- Seasonal-home protection
- Storm outages
- Aging pumps
- Battery backup
Egress Window Installation in Fontana
A lower-level bedroom in a Fontana home needs an egress window large enough for emergency escape, and on a bluff it can add a beautiful view of the lake.
Wells on the uphill side need drainage tied in so they don't fill during storms, and the opening must be cut and supported properly.
We size and place the window, cut the opening and install the well and drainage in one project. Egress work typically requires a permit from the Village of Fontana, and we'll help with it.
- Bedroom egress
- Light and views
- Drained wells
- Village permits
Questions From Fontana Homeowners
FAQs: Foundation Repair in Fontana, WI
Do you serve lakefront and hillside homes in Fontana?
Yes. We serve homes throughout Fontana-on-Geneva Lake, from the shoreline to the bluffs.
Why does my uphill wall crack or leak?
It holds back the hillside and the water in it. Drainage and reinforcement usually address both the leaks and the cracks.
Can you reach a steep, wooded lot with equipment?
Often, yes. We evaluate access first and plan around slopes, trees, retaining walls and landscaping.
How do I keep a seasonal home's basement dry?
A sump pump sized for the house, a battery backup and an alarm give you three layers of protection while you're away.
Can an older cottage foundation be repaired?
Yes. We repair and waterproof the older stone and block foundations found in cottages around the west end of the lake.
Is a backup sump pump worth it in Fontana?
For bluff and lakefront homes, especially seasonal ones, it's one of the best upgrades you can make.
What happens if my drain outlet clogs?
Water backs up behind the foundation and comes in at the uphill wall or through the floor. Clearing or rebuilding the outlet usually stops it.
Who handles permits in Fontana?
The Village of Fontana generally requires a permit for structural repairs and egress openings. We'll confirm with you before work begins.
