What We Build

However you want to use the space.

Most basements combine a few of these. We help you plan the layout that fits your family and your budget.

Family & living space

The most requested finish. A comfortable second living room for movie nights, hosting, and everyday family time.

Guest or in-law suite

Add a legal bedroom with proper egress, so you have real space for guests, teens, or family staying long term.

Full or half bathroom

Adding a bath downstairs makes the space genuinely livable and adds serious resale value.

Wet bar & kitchenette

A bar, sink, and beverage fridge turn a basement into the place everyone actually wants to be.

Home theater

Wired for sound and built for dark, a basement is the best room in the house for a real theater.

Gym, office & play space

Flexible square footage for a home gym, a quiet office, or a dedicated space for the kids.

The Process

How a basement finish works

Design & permits

We plan the layout, finalize scope, and pull the permits your village requires before any work starts.

Framing, electrical & plumbing

Walls go up, then rough electrical and plumbing, coordinated around inspections.

Insulation & drywall

Proper insulation and moisture-appropriate materials, then drywall, tape, and a clean finish.

Flooring, trim & finishes

Flooring, trim, paint, doors, and fixtures. We clean up daily and finish the punch list with you.

We pull the permits, coordinate the inspections, and keep the site clean. You get one point of contact from start to finish.

Investment

What does finishing a basement cost?

Cost depends on square footage, layout, and whether you are adding a bathroom or wet bar. Most finished basements fall in a predictable per-square-foot range, and we give you an honest number up front.

Every project is quoted after we see the space. Call (815) 949-4711 and we will walk you through it.

Common Questions

Basement finishing FAQ

How much does it cost to finish a basement?
Most finished basements in our area land between $35 and $75 per square foot, depending on layout, whether you are adding a bathroom, and the finishes you choose. Bathrooms, wet bars, and egress windows are the biggest cost drivers. We give you an honest number up front, with no surprise change orders.
Do I need a permit to finish my basement?
Yes. Finishing a basement is structural, electrical, and plumbing work, and your village will require permits and inspections. We handle the permit process and coordinate inspections so the work is done legally and documented for resale.
How long does a basement remodel take?
A typical full basement finish runs 6 to 10 weeks from demo to final walkthrough, depending on scope and how quickly permits and inspections move. Smaller projects go faster. We give you a realistic schedule before we start.
What about moisture and water?
We address it before anything gets covered. That means checking grading and drainage, sealing where needed, and using moisture-appropriate materials on floors and walls. Finishing over an active water problem is the fastest way to ruin a basement, so we deal with it first.
Can I add a bedroom down there?
Yes, as long as it meets code. A legal basement bedroom needs proper egress, usually an egress window or door, plus the right ceiling height and smoke detection. We will tell you honestly whether your basement can support it.
Will finishing my basement add value to my home?
It is consistently one of the better returns in residential remodeling, because you are adding usable square footage without changing the footprint of the house. Adding a bathroom typically improves that return further.
