A successful home remodel starts long before demolition. Every home has its own challenges, whether it’s an outdated floor plan, aging plumbing, older electrical systems, or structural changes needed to create a more functional layout. Taking the time to identify those details early is what keeps projects on schedule and helps homeowners avoid costly surprises later.
As a licensed, insured, and bonded design-build contractor with more than 15 years of experience, we help Orange County homeowners plan, design, and remodel with confidence—from the first walkthrough to the final inspection.
Most full home remodeling projects typically range from $200,000 to $500,000+, depending on your home's size, the extent of structural changes, material selections, and the number of rooms being renovated. Every project is different, which is why we recommend an in-home consultation before discussing an accurate budget.
Most projects take 4 to 8 months once construction begins. The overall timeline also includes planning, design, engineering, and permits, which are completed before construction starts to help the project run more efficiently.
In most cases, yes. Permits are generally required when your project includes structural changes, electrical or plumbing work, HVAC modifications, or changes to the layout. As part of our design-build process, we coordinate permits and inspections whenever they're required.
It depends on the scope of work. For smaller renovations, many homeowners stay in their home. For larger whole-home remodels involving multiple rooms, utilities, or major structural work, temporary housing is often the more practical option.
A full house remodel can include kitchen and bathroom remodeling, flooring, lighting, cabinetry, interior painting, windows and doors, plumbing and electrical upgrades, structural modifications, open-concept layouts, and other improvements based on your goals and the existing condition of your home.
With a design-build approach, one team manages your project from planning and design through permits and construction. This helps improve communication, streamline decision-making, and keep your project moving with fewer surprises along the way.
Many Orange County homeowners start by thinking about remodeling one room. But after living in the home for years—or purchasing an older property—they realize the challenges go beyond the kitchen or bathroom.
If you’re experiencing several of the issues below, it may be more practical and cost-effective to plan a full home remodel rather than tackling separate projects over time.
You may be ready for a whole home renovation if you:
A full home remodel allows every space to be planned together—not one room at a time. The result is a home with a cohesive design, a more functional layout, and a smoother construction process than completing multiple renovations over several years. It’s also an opportunity to identify potential structural, plumbing, or electrical issues early, before they become costly surprises during construction.
When every room has been updated at different times, the home often feels disconnected. Remodeling the entire interior at once creates a more cohesive space where every room flows naturally into the next.
This may include:
One of the biggest reasons homeowners choose a full remodel isn’t because they need more square footage—it’s because they want to use the space they already have more efficiently.
We’ve helped homeowners turn separate kitchens and dining rooms into open gathering spaces, create larger primary suites, add walk-in pantries, and improve traffic flow without changing the home’s footprint.
Depending on your goals, this may include:
Many Orange County homes were built decades ago. Once walls are open, it often makes sense to update aging systems instead of covering them back up and dealing with them a few years later.
Depending on your home, we may recommend:
Not every home needs every upgrade. During the planning stage, we’ll help you understand what’s worth replacing now and what can reasonably wait.
The kitchen and bathrooms are usually where homeowners see the biggest improvement in daily life. Rather than designing these rooms separately, we plan them as part of the entire home so everything—from materials to finishes—works together.
Kitchen improvements may include:
Bathroom improvements may include:
Small details make a big difference in how a home feels. Consistent flooring, lighting, and finishes throughout the home help create a space that feels intentionally designed instead of remodeled one room at a time.
Common updates include:
Some homeowners choose to complete exterior improvements at the same time, especially if they’re planning to stay in the home for years.
Depending on your project, this may include:
A whole home remodel involves hundreds of decisions before construction even begins. In our experience, the projects that go the smoothest are the ones that spend the most time in planning.
Before work starts, we’ll walk through your home, discuss your goals, identify anything that could affect the layout or budget, and determine whether engineering or permits will be required. From there, we coordinate the drawings, approvals, scheduling, and construction so you have one team managing the project from beginning to end.
The cost of a full home remodel in Orange County, CA can vary widely because every home and renovation project is different. In many cases, homeowners invest around $200,000 to $500,000, depending on the size of the home, the complexity of the renovation, and the level of materials and customization. Most full home remodeling projects also take about 4 to 8 months to complete once construction begins.
Here are some of the main factors that can affect your renovation cost:

For smaller or phased remodels, yes, but for full house remodels, we typically recommend relocating temporarily for comfort and safety.
A full renovation involves extensive work on utilities, flooring, and finishes, which can make living conditions challenging. If you prefer to stay, we can discuss phased scheduling or partial isolation of work zones to maintain livable areas where possible.
The most expensive parts of a full home remodel typically involve kitchens, bathrooms, and structural changes.
Kitchen remodels are often the costliest because of cabinetry, countertops, plumbing, and high-end appliances, especially in design-forward homes. Bathrooms follow closely due to tile work, plumbing, and custom fixtures.
If you’re reconfiguring walls, adding beams, or updating major systems like electrical and HVAC, those structural components also add to your investment.
At Kol & Co., we help you prioritize your budget wisely, balancing beauty, function, and long-term value so every dollar enhances your home’s design and livability.
