What type of basement remodeling are you looking for?
Tell us what you have in mind — your matched pros will handle it:
Family / rec room
Living space, home theater, gym, or play area.
Add a bedroom
Guest suite with an egress window for code and safety.
Add a bathroom
Plumbing rough-in, full bath, or wet bar.
Full build-out
Wet bar, kitchenette, or a separate in-law / rental unit.
Waterproofing
Sump systems and moisture control to keep it dry.
Three things Chicago homeowners need to know.
1
Water comes first
Clay soil and old foundations make waterproofing and a good sump system must-haves, not extras.
2
Watch the ceiling height
Vintage Chicago basements can be low; a pro confirms you meet code before you plan.
3
Egress + permits
Any bedroom needs an egress window and a permit. It's about safety, not red tape.
The process
What to expect from a basement remodel in Chicago
Timeline
Waterproofing first, finishes last
A basement project starts with moisture control and waterproofing, then framing, insulation, electrical, drywall, flooring, and finishes — plus an egress window and permit if you're adding a bedroom. Most finished basements take 4–8 weeks.
Value
More livable space for the money
Finishing a basement is one of the best ways to add livable square footage for the money, and a dry, finished lower level — especially with a bathroom or rental unit — adds real value.
