What a Long Grove basement remodel involves
Basement Remodeling in Long Grove is priced after an in-home visit. Cost and timeline depend on scope and finish level.
Mechanicals
HVAC, ductwork, and plumbing routing in a Colonial Long Grove home are mapped before framing, since ceiling height is usually the binding constraint.
Use planning
Family room, guest suite, theater, wet bar, or gym: deciding the split is the first design problem, not the last.
Permits
Village of Long Grove Building Department, 3110 Old McHenry Road, Long Grove, IL 60047 (847-634-9440). Office hours Monday through Friday, 8 a.m. to 4:30 p.m. Projects on properties with private well or septic also require Lake County Health Department review. We submit, schedule inspections, and close out the project.
When to remodel
Signs your Long Grove basement remodel is ready
The lower level is storage for a large home
Estate homes in Long Grove often have between 1,200 and 2,500 square feet of lower-level space currently used for storage, mechanicals, and laundry. Finishing it as a media room, wine cellar, or in-law suite changes how the whole estate functions.
You want a guest or in-law suite below grade
An estate basement bedroom, full bathroom, and small kitchenette can host extended family or multigenerational living without adding above-grade footprint.
You want a dedicated entertainment level
Estate-scale media rooms, wet bars, wine cellars, and home theaters work best on the lower level, where acoustic, lighting, and mechanical planning can be isolated from the main living floors.
A previous finish is dated or carries moisture
If the lower level was finished one or two renovation cycles ago, the typical problems are dated finishes, low ceilings, poor lighting, and lingering moisture. Each of those is resolved by reworking ceiling height, drainage, and lighting at the framing stage.

Local difference
Why Long Grove kitchen and bathroom remodeling is different
Long Grove remodels are usually about bringing larger custom homes up to date without flattening their character. Compared with denser suburbs, the challenge is proportion, connection between rooms, and finish continuity across a broader footprint.
FAQ
Basement Remodeling in Long Grove: common questions
How long does a basement remodel take in Long Grove?
Most Long Grove basement projects run ten to twenty weeks depending on scope. Adding a bathroom, kitchenette, or media room with structural work extends the timeline. The schedule is locked at the end of design.
Do you handle waterproofing as part of a Long Grove basement remodel?
Yes. In Long Grove lower levels, waterproofing, drainage, vapor barriers, and moisture-appropriate material selection are scoped as part of the design. A finished basement that skips moisture work fails eventually, so we treat it as a foundational decision rather than an add-on.
Do you handle permits for basement work in Long Grove?
Yes. Village of Long Grove Building Department, 3110 Old McHenry Road, Long Grove, IL 60047 (847-634-9440). Office hours Monday through Friday, 8 a.m. to 4:30 p.m. Projects on properties with private well or septic also require Lake County Health Department review. Egress windows, electrical service upgrades, and bathroom additions require permits and inspections. We manage every submission and inspection.
Can you add a full bathroom to a Long Grove basement?
Yes, in most Long Grove homes. Plumbing routing depends on the existing waste line elevation and may require an ejector pump. We confirm feasibility during the design phase before the bathroom is locked into the floor plan.
