Finished Basements, Done Right

An unfinished basement is square footage you're already paying for — in your mortgage, your taxes, and your heating bill — without getting any use out of it. Finishing it is one of the highest-value projects a homeowner can take on: it adds real living space without an addition, and it makes the whole house work better for how your family actually lives.

We are local professionals who specialize in basement finishing and remodeling. That focus matters. Basements have their own rules: moisture management, egress requirements for bedrooms, ceiling-height realities in older homes, and the permit and inspection process your village requires. We handle all of it — design, permits, framing, electrical, plumbing, HVAC tie-in, insulation, drywall, flooring, trim, and paint — so you deal with one contractor and get one finished space.

If your basement is currently concrete walls and exposed joists, or a half-finished space from a previous owner that never got completed right, call (708) 665-4874 today.

Our Services

• Basement Finishing — Full conversion of unfinished basements into living space: framing, insulation, electrical, drywall, flooring, ceilings, and trim.
• Basement Remodeling — Reworking outdated or poorly finished basements: new layouts, updated finishes, better lighting, and modern living spaces.
• Basement Egress Windows — Code-compliant egress windows and window wells for basement bedrooms, installed to meet Illinois residential code requirements.
• Basement Bathroom Additions — Full and half baths roughed in and finished below grade, including ejector pump systems where gravity drainage isn't available.
• Waterproofing Before Finishing — A dry basement is the foundation of a finished one. We make sure yours is dry before a single sheet of drywall goes up.

Not sure where to start? That's what the free estimate is for. We'll walk your basement, talk through what you want the space to become, and give you an honest read on what's possible — and what it takes.

Why Homeowners Choose Baseline Basements

Basements are all we do. Not kitchens, not additions, not whole-house remodels. Basement finishing and remodeling — which means we've solved the moisture, ceiling-height, egress, and permit puzzles specific to below-grade living space many times over.

Dry first, finish second. The most expensive basement finish is the one you do twice. We verify your basement is dry — and fix it if it isn't, through our sister company Baseline Waterproofing — before finishing begins. Drywall over a water problem is just a future demolition project.

Code-compliant work, permitted and inspected. We pull the permits your village requires and build to the inspections your inspector expects: framing, electrical, plumbing, and final. No shortcuts that cause problems at resale.

One contractor, start to finish. Design, permits, and every trade under one roof. You don't coordinate electricians, plumbers, and drywall crews — we do.

Upfront, itemized pricing. Your free estimate includes a clear written scope: what's included, what it costs, and how long it takes. No vague allowances, no surprise change orders for work that should have been in the plan.

Clean, respectful crews. Floor protection upstairs, dust control, and a full cleanup when the job is done. We treat your home like our own.

Frequently Asked Questions

How much does basement finishing cost? Most full basement finishes in our area land between $30,000 and $60,000 depending on size, whether you're adding a bathroom, and the level of finishes — larger projects with bedrooms and full baths run higher. The only honest number comes from seeing your basement, which is why estimates are free. Read our cost guide for what drives the price.

How long does it take? A typical full basement finish takes four to eight weeks once permits are in hand. Bathroom additions, egress window excavation, and custom work add time. We'll give you a firm timeline with your written estimate.

Do I need a permit to finish my basement? In most of our service area, yes — and you want one. Permits trigger the inspections that verify electrical, plumbing, and framing are done safely, and unpermitted work causes real problems at resale. We handle the permit process for you.

My basement gets damp sometimes. Can I still finish it? Not until it's dry — finishing over moisture ruins drywall, flooring, and everything you paid for. Read why waterproofing comes first, then call us. We'll assess the moisture honestly before quoting any finishing work.
