While we build

How we protect your home while we work.

Floors and pathways covered

Protective board and runners go down before the first tool comes in, from the entry to the work zone.

Dust stays in the work zone

Plastic containment walls and sealed vents keep the rest of the house livable during demo and sanding.

The same crew, every day

One in-house team from demo to final walkthrough. You learn our names, no rotating subcontractors in your home.

Clean end to every day

Tools stored, site swept, walkways clear. You should never dread coming home during a remodel.

Licensed and insured on every job

Full licensing and insurance certificates shown before work starts, not after you ask twice.

Nothing is done until you agree it is

A final walkthrough together, punch list closed out, and a 2-Year Workmanship Warranty in writing.

    Send the form or call (224) 284-4533. A real person from the crew - not a call center - gets back to you within one business day.

  2. Free in-home visit

    We walk the space together, take measurements and talk through what you actually want. No fees, no pressure, no obligation.

  3. Written estimate in 48 hours

    A detailed, itemized estimate in writing within 48 hours of the visit - so you can compare it line by line against any other bid.

    No follow-up hammering, no expiring discounts. When you are ready, the same in-house crew that quoted it builds it - backed by a 2-year workmanship warranty.

Before you ask

Five questions every basement client asks first.

Plain answers — the kind we'd give a neighbor over coffee, not the ones written for a brochure.

  • How much does finishing a basement cost in the Chicago suburbs?

    An open finished space — framed, insulated and finished — typically runs $25,000–$45,000. A full living level with a bathroom and smart storage is $45,000–$80,000, our most common basement project. Premium lower levels with a theater, guest suite or wet bar run $80,000–$150,000+. Itemized written estimate within 48 hours of the free visit.

  • How long does a basement remodel take?

    Most basements take 5–8 weeks from first framing to final walkthrough, with a written schedule up front. The work zone is downstairs and sealed off, so daily life upstairs barely changes.

  • What about moisture? Our basement gets damp.

    Moisture is handled before anything else: we test, seal and correct drainage issues before a single stud goes up. A finished basement is only as good as what's behind the drywall — that's the part we never rush.

  • Do we need permits or egress windows?

    We pull all permits and schedule the inspections. If you want a legal bedroom downstairs, code requires an egress window — we cut, frame and waterproof those ourselves as part of the project.

  • Can you add a bathroom down there?

    Yes — a full bathroom is part of most basement projects we build. We handle the plumbing rough-ins, ejector pit if needed, and ventilation, all to code and all by our own crew.
