The investment
How much does a basement remodel cost in Winnetka?

These ranges are for early planning across Cook County.

You receive a written fixed-price proposal before construction begins.
The time to build

Winnetka specifics
What makes basement remodeling in Winnetka different
West Winnetka backs onto the Skokie River ravines, and east Winnetka sits near the lake, so drainage and moisture shape every basement plan. Waterproofing, sump and egress are solved before finishes are chosen.
How it works
What happens after you request an estimate
Four clear steps from first visit to final walkthrough, with one team the whole way.
01
Consultation and home assessment
We visit your home, see how the rooms work today, check the structure and mechanicals, and set an initial budget range.
02
Design and material selections
Layout, cabinetry, tile and fixtures designed to suit your home's architecture, with renderings before anything is ordered.
03
Fixed-price proposal and permits
You approve a written fixed-price proposal. We file permits with the Village of Winnetka and confirm material lead times.
04
Construction and final walkthrough
A dedicated project manager runs the trades and inspections through to your final walkthrough.

Basement remodeling in Winnetka: common questions
How much does a basement remodel cost in Winnetka?
Basic finishes run $45K–$80K, full remodels $80K–$160K, and suite buildouts $160K–$280K+.
How long does a basement remodel take?
Construction takes 8–16 weeks. From design to final walkthrough, plan on 12–24 weeks.
Do you waterproof before finishing?
Yes. Drainage, vapor barriers and moisture-safe materials are part of the design, before framing starts.
Do you handle permits in Winnetka?
Yes. We file with Village of Winnetka Community Development, handle Landmark Preservation Commission review when it applies, and schedule every inspection.
Can you add a full bathroom in the basement?
Usually, yes. If the drains sit below the sewer line, we add an ejector pump so the bathroom works like any other.

The transformation of our kitchen was amazing! The team was skilled and attentive to our needs. Highly recommend! Thank you for such great work!
Love our new kitchen! It was a huge project, but everything came together so well. The team was professional, and we couldn't be happier!!!!
The team did a great job with our kitchen remodel. They really helped us visualize the changes and delivered exactly what we wanted.
Delta did an amazing job on both of our bathrooms. The contractor was very knowledgeable and professional. I will definitely use them for all my remodeling projects in the future.
Excellent work, careful clean-up and easy to work with!
What a difference! Our kitchen feels brand new, and the design is perfect for our needs. Highly recommend!
I can not say enough positive things about the experience working with Kasia and Sebastian. They are top notch! Knowledgeable , professional, hard working, honest and fairly priced. I would recommend them to anyone looking to get a job done. Also, I should mention they are timely and when they say they will be there, they really mean it. Our kitchen turned out beautiful and I am thrilled with the quality as well.
Rebuild of chimney from the roof line up. From all that I can tell / inspect, they have done an excellent quality job, complete with new concrete topper. Yes, I recommend Delta Remodeling for masonry / Tuck-pointing work. Rick.
Delta helped us gut and restore our dated master bathroom. They were extremely helpful in rolling with the various changes that we had to make along the way and being patient as we took a break to figure out some last minute changes to our design. If there was one thing they could have done better, it would be forcing us to be more organized so we wouldn't have had to take a break when things didn't go as planned. If you're looking for flexibility and a make anything work attitude, Delta is the company for your project.
Our home renovation was a great experience. The team and dedication craftsmanship resulted in a new beautiful and functional new space.
Filip is a fantastic project manager, the team showed up on time did really good work, would definitely recommend them.
