What does KCK Construction & Remodeling do?
KCK Construction & Remodeling is a family-owned, licensed design-build general contractor based in Concord, CA. We design and build kitchen and bathroom remodels, whole-home renovations, home additions, ADUs, custom homes and commercial projects, with one team handling design, permits and construction from the first meeting to the final walkthrough.

What does design-build mean for my project?
Design-build means one company handles your design, plans, permits and construction. You work with one team and one point of contact instead of hiring a designer, a drafter and a builder separately, which keeps the budget, the schedule and the decisions in one place.
Can I see my project before I approve the estimate?
Yes. Our in-house design team creates realistic 3D renders of your space for every client, so you see the layout, finishes and materials before you approve the estimate. We adjust the design until it feels right, then build the estimate from the approved design.
Do you handle permits and engineering?
Yes. We prepare permit-ready plans and blueprints for your city and manage plan check, corrections and inspections. When a project needs structural or civil engineering, it is provided through our licensed engineering partners and coordinated by our team.
How do I get started?
Request a complimentary consultation online or call (510) 978-3259. We visit your home, take measurements and talk through your goals and budget. From there we design your project in 3D and prepare a detailed, itemized estimate.
How much does a remodel, addition or ADU with KCK cost?
Every project is priced individually because size, design, materials and permits vary from home to home, so KCK does not publish set prices. Schedule a consultation and we will review your goals, visit the site and prepare a detailed, itemized estimate. Call (510) 978-3259 or email Office@kckconstructionr.com to schedule your consultation.
