My basement wall near Bohners Lake gets damp every spring even without a storm — is that normal?

Yes, and it’s one of the most common calls we get from the neighborhood. Bohners Lake sits inside a natural basin with a high water table, and many homes near the shoreline were built with the foundation closer to grade than modern construction allows. When the lake and surrounding groundwater rise with spring snowmelt, hydrostatic pressure pushes moisture through foundation walls, cove joints, and old block or stone construction even without a single drop of rain falling that week. This is different from storm-driven flooding, and it usually calls for a different fix — moisture mapping to confirm the seepage pattern, structural drying if the dampness has reached framing or finished space, and a conversation about exterior grading or a sump system if the problem repeats every year.

I have a seasonal cottage at Bohners Lake I only visit on weekends — what's my biggest water risk?

Burst pipes from freezing are the biggest risk for any home around the lake that sits empty for stretches at a time, especially cottages that started as summer-only structures and were later converted with plumbing added into unheated crawl spaces or exterior walls. A pipe can freeze and split on a Tuesday and run unnoticed until you arrive the following weekend, by which time water has soaked subfloor, insulation, and drywall throughout the home. We recommend a monitored temperature sensor or smart water shutoff for any part-time lake property, and if you do come home to standing water, call us immediately — the sooner we can start extraction and moisture mapping, the more of the structure we can dry in place instead of removing.

Does the Bohners Lake Sanitary District affect how backups happen in my neighborhood?

It can. Because Bohners Lake is served by a sanitary district rather than a large municipal sewer system, the infrastructure serving the lake’s homes has grown in stages over decades as cottages were added and converted, and heavy rain events can push more inflow and infiltration through aging lines than they were sized to handle. When that happens, homes at lower points in the system can see sewage back up through floor drains or fixtures — a Category 3 loss that requires contaminated material removal, disinfection with EPA-registered antimicrobials, and full structural drying, not just a wet vac and a fan. If you’ve had a backup before, it’s worth asking your sanitary district about known trouble spots in your section of the system.

How is water damage different in an older Bohners Lake cottage than a newer Burlington home?

Older cottages around the lake — many dating back to the resort era when Antony Bohner first opened the shoreline to vacationers — were built with different materials and different assumptions than a modern subdivision home. Plaster-and-lath walls, balloon framing, and additions layered onto the original structure over decades all change how water travels once it gets in, often wicking sideways through wall cavities instead of staying contained to one room. We adjust our drying approach for that: more attention to hidden cavities, careful demolition decisions that respect original materials where they can be dried in place, and closer moisture monitoring since these homes don’t always dry at the same rate as new construction.

Can ice damming really cause water damage on Bohners Lake cottage roofs?

Yes, and it’s a common winter call around the lake, particularly on older cottages with lower-pitched rooflines and attics that weren’t insulated to modern standards. Heat escaping from the living space warms the roof deck, melts snow, and that meltwater refreezes at the colder eaves, building a ridge of ice that backs water up under the shingles and into the attic or exterior walls. Once that water gets past the roofline, it can travel down into insulation, drywall, and even electrical fixtures before it’s noticed. We handle both the water extraction and structural drying after an ice dam event, and we can also point you toward the ventilation and insulation fixes that keep the same thing from happening again next winter.

Serving Bohners Lake — Burlington’s Own Lake Community

Bohners Lake takes its name from Antony Bohner, a French immigrant who opened a resort on the lake’s shore in the 1800s, drawing vacationers off the Fox River Valley Railroad line into what old Burlington Historical Society records call “Camp Lonesome.” What began as tent camps and rented cottages along the east and west shores grew into the year-round neighborhood that surrounds the lake today — cottages converted decade after decade, a resident association still watching over the water, and streets like Park Street and the roads around Oakwood Hills lined with homes that trace back to that original resort era. The lake itself sits inside the Town of Burlington, just south of the city, close enough that residents consider themselves Burlington locals even though Bohners Lake is its own census-designated place with its own Sanitary District managing wastewater for homes built close to the shoreline.

That closeness to the water is baked into the neighborhood’s plumbing. Bohners Lake covers about 135 surface acres with a muck-and-sand bottom and a maximum depth of 30 feet, which means the water table around the lake sits high nearly everywhere, and homes near the shoreline manage groundwater pressure against their foundations every spring. Add the shared septic infrastructure that many older lake cottages still rely on, decades of additions and remodels stacked onto homes never built with modern plumbing in mind, and a mix of full-time residents and weekend owners who aren’t always around when a pipe fails, and you get a lake community with more than its share of water-related emergencies.

We handle:

Basement and crawl space seepage from high groundwater near the shoreline
Sump pump failure in homes along Park Street and the lake’s east and west shores
Septic and sanitary district backups affecting lakefront properties
Storm and wind damage from lake-effect weather crossing the open water
Ice damming on older cottage roofs during Wisconsin winters
Burst pipes in seasonal or weekend homes left unheated
Basement flooding after spring snowmelt and heavy rain events
Mold growth in crawl spaces with limited ventilation near the water
Water damage from aging plumbing in homes converted from seasonal to year-round use
Storm sewer and drainage backups on low-lying streets near the lake

How We Reach Bohners Lake Fast from Our Burlington Base

Bohners Lake sits close enough to our Industrial Drive facility that we’re often on scene before the caller has finished explaining what’s happening. From our shop we head south on Pine Street or pick up the Burlington Bypass — the four-lane stretch of Highway 11/36/83 that routes around the south side of the city — and take it to the Highway 11 interchange near the south edge of town. From there it’s a short run down Park Street, the main road tracing the lake’s east shore, to reach homes along the water. For the west shore and the streets around Oakwood Hills, we cut through on the connecting roads off Park Street rather than circling the entire lake, which keeps the drive under ten minutes from dispatch in most conditions.

Because Bohners Lake falls inside the Town of Burlington, we’re not crossing county lines or fighting through another municipality’s traffic patterns to get there — it’s essentially our backyard. That matters for a lake community where the emergency call often comes from a weekend cottage owner checking on a property after a storm, or a full-time resident who just watched a sump pump quit during a downpour. A five- to ten-minute arrival window means the difference between drying out a wet crawl space and pulling out saturated subfloor after water has had all day to travel through a home built close to grade.

What Drives Water Damage and Mold Risk at Bohners Lake

Bohners Lake’s risk profile is a function of sitting inside a natural basin barely above the water line. At roughly 846 feet of elevation and covering about 2.3 square miles including the lake itself, the community has almost no room between typical foundation depth and the groundwater table, particularly for homes built along the original resort-era shoreline where lots are narrow and close to the water. That high water table means many basements here experience hydrostatic pressure pushing against foundation walls every spring, whether or not the lake itself has risen — seepage through cove joints and old stone or block foundations is common even in years without heavy flooding.

The lake’s muck-and-sand bottom composition also plays a role in how quickly the surrounding water table responds to rain. Unlike a lake with a hard, rocky bottom, Bohners Lake’s soft substrate holds water in the surrounding soil longer after storms, which keeps crawl spaces and basements damp for days after a heavy rain event even when there’s no visible flooding. That extended dampness is exactly the condition that lets mold establish itself in floor joists, subfloor, and insulation before anyone notices a problem.

Winter adds its own risk. Many homes around Bohners Lake started as seasonal cottages built for summer use and were later converted for year-round living, which means plumbing runs were often added into crawl spaces, exterior walls, and additions that weren’t part of the original insulated structure. A hard freeze finds those weak points fast, especially in homes where owners are away for a few days at a time. Ice damming is a related winter hazard on the older, lower-pitched cottage roofs that ring the lake, where heat loss from an under-insulated attic melts snow that refreezes at the eaves and backs water up under the shingles.

Because Bohners Lake relies on a Sanitary District rather than a single large municipal sewer system, aging infrastructure serving decades of added homes can also be a factor in backups during periods of heavy rain, when inflow and infiltration push more water through the system than it was built to handle — a dynamic property owners here should factor into how they plan for wet-weather risk.
