Home services around Lake Como.
Cottage-era neighborhoods, year-round conversions and a shoreline split between sanitary-district sewer and private septic. We've serviced Como homes from East Troy for generations.
Does O'Leary service homes around Lake Como?
Yes. The Lake Como shoreline in the Town of Geneva is about 20 minutes from our East Troy shop, and we work on both sides of its infrastructure split: homes inside the Lake Como Sanitary District's sewer-and-water boundaries, and homes just outside them running on private wells and septic systems. Plumbing, heating, cooling, electrical and water treatment — one call covers all of it.

What Lake Como homes are working with
Lake Como is a 955-acre, shallow spring-and-seepage lake (max depth about 9 feet, per the Wisconsin DNR's water records) whose north and south shores filled in as resort-era cottage neighborhoods. The Lake Como Beach Property Owners' Association, founded in 1926, still maintains 1.3 miles of lakefront, beaches and piers on the north shore.
Much of that cottage stock has been converted to year-round living, one remodel at a time. That means 60-amp panels feeding modern loads, supply piping several generations old, and furnaces squeezed into crawlspaces that were never designed for them. We modernize these systems in the order that protects you fastest.
Utilities here are genuinely mixed: sewer and water inside the Lake Como Sanitary District boundaries, private wells and septic just outside them — the Town of Geneva has even commissioned DNR-funded sanitary surveys of south-shore septic systems. Knowing which side of that line your home sits on changes what your plumbing needs, and it's the first thing we confirm.
The systems work Lake Como homes actually need
Cottage conversions carrying modern loads
Seasonal cottages converted to year-round homes often still have original panels, piping and ductwork. We sequence panel, piping and heating upgrades so the house catches up safely.
Well-or-municipal uncertainty
Two houses on the same street can be on different water. We confirm your source, test private wells to state guidance, and size treatment to actual results.
Shallow-lake shoreline care
Como is shallow and weedy, and septic performance near the shore draws real scrutiny. Septic-safe fixtures, smart discharge routing and careful shoreline electrical protect the lake and your property.

Verified local infrastructure and programs
Sewer and water issues inside the Lake Como Sanitary District boundaries go through the district's administration office on Dell Place (per the Town of Geneva). Homes outside district boundaries typically run on private wells and septic.
For private wells, the Wisconsin DNR recommends testing for bacteria and nitrate every year and arsenic at least every five years. Walworth County Public Health sells certified test kits (bacteria, nitrate, arsenic, lead) at its Elkhorn office.

Lake Como questions we hear the most
How do I know if my Lake Como home is on municipal water or a private well?
It depends on whether you're inside the Lake Como Sanitary District boundaries — the district office on Dell Place can confirm, and so can we during a service visit by checking your meter, pressure tank and piping. If you're on a well, we'll recommend the state-guidance test schedule.
Our cottage was converted to year-round living decades ago. What should we upgrade first?
Safety first: the electrical panel if it's still 60-amp or fuse-based, then the water heater and any original galvanized supply lines. Heating comes next — a properly sized modern furnace or heat pump usually replaces an oversized retrofit unit.
Is my septic system a problem for the lake?
Aging or failing septic near a shallow lake like Como is exactly what the Town of Geneva's sanitary surveys were looking for. If your drain field is decades old, an inspection is cheap insurance — and we spec septic-safe fixtures and softener discharge on every job.
Can you run power to our pier on Lake Como?
Yes. Shoreline electrical gets code-required GFCI protection, and pier permits on Lake Como go through the LCBPOA for association land or the Town of Geneva's Lake Committee otherwise. We confirm the permit path before any trenching near the water.
How fast can you get to Lake Como in an emergency?
We're about 20 minutes away in East Troy and run 24/7 emergency service. No-heat calls in winter and active leaks jump the queue.
