What we build
One bathroom or a whole floor.
Permits, building management, trades and the finish work you'll look at every day — one contract, one team, one person to call.
Kitchens
The room everyone ends up in. New layouts, cabinetry, waterfall counters and tile layouts planned before the first cut.
Bathrooms
Walk-in showers, primary suites and powder rooms — waterproofed properly behind every tile, because that's the part you never see and always pay for.
Full interior renovations
Whole condos and homes, gutted or refreshed. We work within freight-elevator bookings, HOA rules and building-manager schedules every week.
Commercial interiors
Offices, medspas, retail and amenity floors — built around your opening date, your residents and your landlord's rulebook.
Construction management & estimating
Takeoffs, budgets, scopes of work and project management for owners, developers and contractors.
Payment options
Pay the way that works for you.
Cash, check, Zelle or credit card. Progress payments are laid out in your written proposal, with the final payment at completion.

Why Ethos
Our own crew, on every job.
We keep the trades that decide how a room looks and feels — carpentry, tile and paint — in-house. That means the same trusted crew and the same standard on every project, and one team accountable for the result.
Established in 2019, Ethos C.S., LLC is a licensed City of Chicago general contractor based in Morton Grove. Every job is run by Christos Kostopoulos, who spent 15 years managing projects for larger construction firms on multi-million-dollar work before founding Ethos. Ethos is Greek for character — and that's what we put into every job.
Our own crew
Carpentry, tile and painting done in-house, held to one standard.
Estimates you can read
Line-item pricing by scope, so you know what's included before work starts.
15 years of big-job experience
Your project manager comes from multi-million-dollar construction — and runs your job from walkthrough to punch list.
We stay in touch
Calls and texts answered, replies within one business day, and regular updates while the work is underway.
Clean, occupied-home sites

★★★★★“Christos and team completed a full renovation of my 2 bed/2 bath loft condo in the west loop in 6 weeks! They did a great job and made the project as stress free as possible for me. Highly recommend. Pricing was fair in my opinion. Will use Christos again for my next project.”
★★★★★“I worked with Ethos on two commercial office renovation projects and they were on time, on budget, and they are great at communicating the status of the project. We will definitely use them again!”
