Chenequa essentials
Three local facts set the plan for a larger Chenequa remodel before any finish is chosen: the house treats its own wastewater, the village requires a permit once work passes $2,000, and changes seen from outside can bring Plan Commission review.
Budget
$12k–$80k+
Per room, from a guest bath refresh to a full lake-house kitchen. Several rooms together become one written figure after the walkthrough.
Septic first
County review
With no public sewer anywhere in the village, Waukesha County evaluates the private system before a remodeling permit is issued.
Village review
Inside vs outside
Interior-only work skips the Plan Commission. Changing a window’s size or style needs a permit and can add a monthly meeting to the schedule.
Lake house rooms
In Chenequa a larger remodel often links rooms built in different decades: an original lakeside core, a postwar wing, a newer kitchen. T And J plans them as one project with one crew and one finish plan, and the biggest rooms have their own service pages.

Kitchen
The kitchen usually anchors a Chenequa remodel, because every new sink and dishwasher drains to the septic system and draws from the well. Cabinets, stone and layout are planned around those runs, and a temporary kitchen is set up before demolition.
Scope
Refresh to full rebuild
Water
Well supply, septic drain
Range
$17k to $80k+

Bathroom
Period baths in older lake houses keep their proportions while the wet walls are rebuilt with a membrane behind the tile. With several baths in the house, one is always left working.
Scope
Guest bath to primary suite
Wet walls
Membraned, water tested
Range
$12k to $45k+

Lower level
Lower levels near the water are checked for moisture before anything is promised, then finished as family rooms, guest bedrooms with egress or a bath. A new bedroom on a septic property widens the county review, so it is decided early.
Scope
Rec room to guest suite
Code
Egress, 7 ft ceiling, alarms
Range
$20k to $60k+

Layout
Older Chenequa houses often keep a closed kitchen, a separate dining room and a back hall that turns away from the water. T And J checks whether the wall between them carries load, has an engineer size any beam, and reroutes what runs inside it before the opening is widened.
Walls
Opened, moved or removed
Structure
Engineered beam, inspected
Result
Rooms that flow together

Finish work
Once rough inspections pass and concealed insulation has been checked, floors, doors, casing and lighting go in across every room in scope. Matching new trim to original profiles in an older lake house is planned at the quote stage, not improvised.
Flooring
Hardwood, LVP, porcelain
Carpentry
Casing, doors, built-ins
Lighting
Recessed, pendant, dimmable

Well to septic
Every house here runs on its own well and septic, so plumbing updates start at the pressure tank and end at the line out to the tank. Older panels, galvanized supply and heating that no longer suits the plan are replaced while walls are open, and when a remodel passes half the assessed value, village code encourages moving the electric service underground.

Materials
Older Chenequa homes were often built in stages, so floors and trim change from wing to wing. A multi-room remodel is the chance to pick one floor, one casing profile and one lighting plan and carry them through every room in the project.
Oak or maple, site-finished to match older floors or prefinished.
Waterproof plank for the lake entry, mudroom and kitchen in one run.
Hard-wearing floors for baths, laundry and back entries.
Casing, base and doors matched room to room, including older profiles.
Dimmable layouts planned per room on the updated circuits.
Kitchen, vanity and bar counters chosen from one slab family.
Mudroom lockers for lake gear, media walls and pantry storage.
A single color plan, with washable finish on busy walls.

Housing eras
Census estimates for Chenequa cover only about 284 homes, nearly all detached, with a median build year near 1973, so the shares carry wide margins. About 34 percent went up between 1970 and 1999, 28 percent between 1940 and 1969, 19 percent before 1940 and 19 percent since 2000. Each era leads to a different remodel.

The biggest group at about 34 percent. Wooded parcels, a kitchen closed off from the family room, and baths that have rarely been touched since the house was built.

About 28 percent of homes. Postwar ranches and lake cottages with small rooms, a load-bearing wall between kitchen and dining, and panels sized before modern kitchens.

Roughly 19 percent, including rebuilds of older lake homes. Layouts usually work, so kitchens and baths are updated in place and walls stay where they are.

About 19 percent, many of them former summer houses on Pine and Beaver Lake. Plaster and original woodwork are protected, and old wiring is replaced while walls are open.

Every main room reworked in one program, often with new wiring, well-side plumbing, floors and trim, phased so the household can keep living in the house.
Chenequa permits
The village sets a dollar line: remodeling estimated at $2,000 or more needs a building permit, while painting or carpeting counts as maintenance. Electrical, plumbing and HVAC permits go on the same consolidated village form.
The Village of Chenequa issues the permits and contracts inspection to Lake Country Inspections, whose inspector works by appointment. Because no home here is on public sewer, Waukesha County runs a Preliminary Site Evaluation of the septic system before the permit, and more bedrooms can mean a soil test and a tank capacity check. Interior remodeling skips the Plan Commission; new window sizes or styles need a permit and can go before it, with filings due the 15th of the prior month. Inspections come at rough carpentry, plumbing, electrical and heating, and again once concealed insulation is in. Starting early brings a double permit fee. A permit stays valid 24 months, and the inspector issues a certificate of occupancy when work is complete. T And J files each step.

Village hours
A Chenequa remodel runs on two calendars. The county septic review and village permits come first; after that, any part of the job that happens outdoors, from deliveries to dumpster swaps, keeps to village hours of 7:00 to 6:00 on weekdays and 9:00 to 3:00 on Saturdays.

Nearby
The crew drives out from 985 Georges Avenue in Brookfield to the lake villages of western Waukesha County. Around Chenequa, sewer service, permit offices and housing ages change from one municipality to the next, so each town’s page covers its own rules.
WIS 83 carries the crew north between Pine Lake and Beaver Lake toward Merton, and south to Hartland, where a different municipality issues the permits.
Nashotah, Okauchee, Oconomowoc, Delafield and Wales, where lake houses and older cottages raise many of the same layout and lower-level questions.
Sussex, Lannon, Pewaukee, Waukesha and Brookfield, closer to the Georges Avenue shop the crew leaves from.

Questions
Questions about your own Chenequa house: (262) 352-9525.
Mostly the order of approvals. Waukesha County evaluates your private sewage system before any village building permit for remodeling is issued, confirming the system works and meets setbacks. Adding bedrooms can bring a soil test and a tank capacity check. Inside, every relocated sink or shower has to reach the drain line to the septic, and new fixtures draw from the well pressure tank.
Usually not. Chenequa code lets the building inspector clear an application that covers only interior or minor exterior remodeling without Plan Commission or Village Board review. Window changes in size or style are handled differently, so T And J confirms the route before dates are set.
Yes, within limits. Village code allows outdoor construction activity, including the outdoor parts of an indoor job such as deliveries and dumpster swaps, from 7:00 to 6:00 on weekdays and 9:00 to 3:00 on Saturdays. Nothing happens on Sundays or holidays.
Often, yes. Many older Chenequa houses keep a closed kitchen and a formal dining room. After confirming whether the wall carries load, T And J has an engineer size the beam, reroutes pipes, wiring or ducts inside it, and the village inspector checks the framing.
Either works. Doing rooms together shares demolition, permits and finish matching, which lowers the cost per room. A Chenequa building permit is good for 24 months, so a staged plan is scheduled around that term, and John sets out which rooms go in each stage.
A bathroom refresh starts near $12,000, a kitchen runs from about $17,000 to past $80,000, and a basement finish starts around $20,000. Several rooms or a whole house are priced as one fixed figure once John has walked the house.
Most Chenequa households stay, since these houses usually have several bathrooms and room to spread out. T And J sets a written sequence showing which rooms are closed and when, and keeps a working bath and a temporary kitchen available.
The T And J in-house crew does the work, and Teli and John Karampetsos quote and oversee each project. Electrical and plumbing permits are held by licensed trades, as Wisconsin requires.
