What basement finishing with ADS covers
Moisture work, framing, insulation, electrical and lighting, drywall, ceilings, flooring, doors and trim. Most of the basements we build include a bathroom, and some add a bedroom, an office or a wet bar. Our crew handles the plumbing too, including an ejector pump when the bathroom sits below the sewer line.
Moisture comes first
Spring thaw and heavy rain are when Chicago-area basements show water. Before any framing, we look for white mineral stains on the walls, cracks, a sump pump that runs constantly or has quit, and downspouts emptying right next to the foundation.
Water problems get corrected before a single wall goes up. Sometimes that means drain tile or a new sump pump, and we raise it at the estimate so it is part of the plan, not a surprise later.
How the job runs
Layout and permit. Rooms are planned around the furnace, water heater, sump, steel posts and ductwork. We pull the permit and schedule every inspection.
Moisture work and framing. Water issues are fixed, a vapor barrier goes on the slab and walls, then framing and insulation.
Egress. A room can only be a legal bedroom with an egress window. We cut the foundation, set the window and well, and waterproof them.
Rough-in and inspection. Wiring, plumbing and ducts are run and inspected before drywall. Where the ceiling is low, we keep ducts and lights between the joists wherever the layout allows, instead of dropping the whole ceiling.
Finish. Drywall, ceiling, flooring over the prepared slab, doors, trim, paint and fixtures. Final inspection, then a walkthrough with you and your 2-year written workmanship warranty.
Timeline, cost and the written schedule
Most basements take 5 to 8 weeks and cost $25,000 to $80,000. Before we start, you get a written schedule showing each phase and when the inspections fall. If a moisture fix or an inspection moves a date, we tell you right away, with the new date.
The price moves most with square footage, a bathroom (and whether it needs an ejector pump), egress windows, how much water work comes first, a wet bar, and how much ductwork has to be rerouted to protect ceiling height.
What to have ready
Clear out the basement, or tell us what has to stay so we can plan around it. Keep the furnace, water heater and electrical panel reachable. If the basement has ever taken on water, tell us when and where. That history shapes the plan.
Basements we have finished

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.
