From rough framing to the final coat of paint — every trade, every detail, handled by Alta's certified crews.
Framing & Layout Planning
We design and frame your basement floor plan — bedrooms, offices, media rooms, or open concepts — built to local code with pressure-treated lumber where required.
Insulation & Moisture Control
Proper insulation is critical in Illinois basements. We install closed-cell spray foam or rigid board insulation with vapor barriers to prevent moisture intrusion and future mold problems.
Drywall & Ceiling Systems
From standard flat ceilings to drop ceiling grids for mechanical access, our drywall installation delivers smooth, paint-ready walls every time.
Electrical & Lighting
Our licensed electricians add circuits, recessed lighting, outlets, and data ports — all permitted and inspected. Related: lighting installation and panel upgrades if needed.
Flooring Installation
We install moisture-resistant luxury vinyl plank, engineered hardwood, carpet, and tile — chosen for basement-specific performance in the Chicagoland climate.
Basement Bathroom Add-Ons
Add a half-bath or full bathroom to maximize your basement's value. We handle plumbing rough-ins, bathroom remodeling, and ejector pump installation for below-grade drains.

Basement Finishing FAQs
Straight answers to what homeowners ask most before starting a basement finishing project.
Basement finishing costs in the Chicago suburbs typically range from $25–$60 per square foot depending on the scope, finishes, and whether plumbing is added. A 1,000 sq ft unfinished basement might cost $30,000–$60,000 for a full remodel with electrical, drywall, flooring, and a bathroom rough-in. Alta provides free, itemized written estimates so you know exactly what you're getting. Request your free estimate here.
Yes. In virtually every DuPage County and Cook County municipality, finishing a basement requires building, electrical, and plumbing permits. As a licensed general contractor, Alta Property Services pulls all required permits on your behalf and schedules all inspections. This protects your home's value and ensures the work meets code — critical when you eventually sell.
Most basement finishing projects in the Chicago suburbs take 6–12 weeks from permit approval to final walkthrough, depending on size and complexity. Adding a bathroom, egress window, or extensive electrical work can extend the timeline. Alta coordinates all trades in-house, which significantly reduces delays compared to hiring multiple subcontractors separately.

We also coordinate directly with your insurance company if the damage was covered under your homeowner's policy.
