Whether you’re updating a home you’ve lived in for years in Costa Mesa or recently purchased a property that needs work, every remodeling project starts with the same question: What’s the best way to make this home work for the way we live today?
Over the years, we’ve worked on everything from opening up compartmentalized floor plans in older Costa Mesa homes to building home additions, remodeling kitchens and bathrooms, constructing ADUs, and building custom homes from the ground up. No two projects are exactly alike. Some homes need structural changes before the design can come to life, while others simply need better planning to make the space more functional.
As a licensed, bonded, and insured design-build contractor, Kol & Co. manages the entire process, from design, budgeting, engineering, and permits to construction and the final walkthrough. Instead of coordinating multiple companies, you’ll work with one experienced home remodeling team focused on making the process as organized and straightforward as possible.
If you’re planning a home remodel or new construction project in Costa Mesa, we’d be happy to walk through your ideas, evaluate your property, and help you understand what’s possible before construction begins.
Every remodeling project starts with a different goal, but one thing we hear often is, “We love our home—we just need it to work better for our family.” Whether it’s an older home with an outdated layout or a growing family that needs more space, remodeling gives homeowners the opportunity to improve how their home looks, feels, and functions without moving.
Common reasons Costa Mesa homeowners choose to remodel include:
The kitchen is often the hardest-working room in the home. When the layout is inefficient, storage is limited, or the finishes feel outdated, even everyday tasks can become frustrating.
Our kitchen remodeling services in Costa Mesa may include:
Before recommending a new layout, we consider how you cook, where you store everyday items, how many people use the kitchen, and how the room connects to your dining and living areas.
We remodel primary bathrooms, guest bathrooms, powder rooms, and smaller hall bathrooms throughout Costa Mesa. Each project is planned around the available space, the condition of the existing plumbing, and the homeowner’s preferred style and level of finish.
Costa Mesa bathroom remodeling services may include:
A full home remodel allows you to improve the entire property through one coordinated plan. Instead of remodeling one room at a time and ending up with disconnected layouts or finishes, a whole-home renovation creates a consistent design throughout the house.
Full home remodeling may include:
An accessory dwelling unit can create flexible space for family, guests, a home office, or potential rental use. We help homeowners plan and build several types of ADUs.
Our ADU services in Costa Mesa may include:

Many remodeling and construction projects in Costa Mesa require permits, especially when the work involves structural changes, home additions, ADUs, new construction, or modifications to plumbing, electrical, or mechanical systems.

By addressing permitting early, we help keep your project compliant with local building codes and reduce delays during construction.
We discuss your goals, budget, lifestyle, and evaluate your property to develop the best approach for your remodel or new build.
We create a functional design, define the project scope, select materials, and establish a realistic budget before construction begins.

Ready to transform your home in Costa Mesa? Schedule your consultation today and let’s build a home that’s designed around the way you live today, and for years to come.
The first step is to schedule a consultation. We’ll visit your home, discuss your goals, budget, and timeline, evaluate the existing space, and recommend the best approach for your project. From there, we’ll guide you through design, budgeting, permits, and construction, so you have a clear plan before work begins.
The cost depends on the size of your home, the scope of work, structural changes, and the materials you choose. Kitchen remodels typically start around $40,000, bathroom remodels around $25,000, and full home remodels generally range from $200,000 to $500,000+.
The timeline depends on the size and scope of your project. As a general guide, bathroom remodels typically take 3–5 weeks, kitchen remodels 6–10 weeks, and full home remodels 4–8 months after planning and permits are complete. Projects involving home additions, structural changes, or custom features may take longer. During your consultation, we’ll provide a realistic timeline based on your specific project and keep you informed throughout construction.
Many remodeling projects require permits, especially if they involve structural changes, plumbing, electrical work, room additions, ADUs, or major renovations. We coordinate the permitting process and required inspections for our clients.
For many homeowners, yes. Completing multiple renovations together can reduce overall construction time, improve design consistency, and avoid repeated demolition or disruption.
Absolutely. As a design-build contractor in Costa Mesa, we handle everything — from design concepts and materials to construction and finishing — so you have one dedicated team managing the entire process.
