Basement Remodeling planned for how Elmhurst homeowners live.
In Elmhurst the basement question often comes down to a bedroom. Whether you’re in an older home near downtown or one of the newer teardown-rebuild houses, families want a legitimate guest room, in-law space, or teen suite below grade, and that word, legitimate, carries real requirements.
A below-grade room can only be called a bedroom if someone can get out of it in a fire. That means a code-compliant egress window and well, sized correctly, with a window that opens fully and a well someone can actually climb. We handle the cut into the foundation, the drainage at the bottom of the well so it doesn’t become a bathtub, and the inspection that makes the room count as one.
Skipping the egress to save a few dollars is the shortcut we see most, and it’s the one that turns up at resale and during permitting. We’d rather do the foundation cut properly once and hand you a room that’s a bedroom on paper as well as in use.
How ADS finishes a basement: moisture first, then framing, egress and permits, and what the written schedule commits us to.

Have a different question? Ask during your free estimate →-
How much does a typical kitchen or bathroom remodel cost?
Bathroom remodels in our area typically run $18,000–$45,000. Mid-range kitchens are usually $35,000–$80,000 — full custom kitchens can reach $120,000+. We give you a detailed estimate in writing after the in-home visit, so you see the numbers line by line before signing anything.
-
How long will my project take?
A bathroom is usually 3–5 weeks from demo to final walkthrough. A standard kitchen runs 6–8 weeks. Basement finishes are 5–8 weeks. We give you a written schedule before we start — and because we use our own in-house crew, we don't lose days waiting on a subcontractor to show up.
-
Do you handle the permits and inspections?
Yes — every time. We pull the permits, schedule the inspections, and meet with the inspectors. You don't deal with the village. We handle Buffalo Grove, Arlington Heights, Lombard, Glen Ellyn, Wheaton, and the rest of our service area.
-
Can we live in the house during the remodel?
Almost always, yes. We seal off the work zone with plastic, set up a temporary kitchen if we're remodeling yours, vacuum daily, and do a deep clean at the end. Most clients stay in the home for the full project — we plan the sequence around your daily life.
-
How do payments work?
A small deposit at signing, then progress payments tied to milestones (rough-in complete, drywall complete, final walkthrough). You never pre-pay for work that hasn't started. Final payment is only released after you sign off on the final walkthrough — not before.
