Fast, Reliable General Contractor Across Costa Mesa
Costa Mesa homeowners call us when they’re done juggling three different subs for one remodel, or when a kitchen wall opened up to reveal something that wasn’t on the original permit. We run a full-service General Contractor operation out of Fontana, sending crews into Costa Mesa weekly for everything from kitchen overhauls to whole-home additions on 92626 tract lots. Call (855) 473-5620 and you’ll get Ruben Castillo on the line, not a call center, and we’ll schedule a free estimate for your project.
You get one contract, one schedule, and one person accountable for every trade on site.
Why San Bernardino Contractors Is Costa Mesa’s Preferred General Contractor Company
We’ve worked enough jobs in the 92626 and 92627 ZIP codes to know the difference between them matters. A kitchen remodel in Mesa Verde means something very different from a kitchen remodel on a Westside bungalow, and we bid accordingly. Homeowners in Costa Mesa keep bringing us back because we quote honestly the first time and write change orders in writing, with the specific brand and line item called out, before any wall comes down.
Our crews know Costa Mesa’s permit office rhythms and the HOA architectural review timelines in the newer master-planned pockets. We show up when we say we’ll show up, and the person you meet at the estimate is the person who answers your calls until the final inspection passes.
Ruben Castillo has built this company around the idea that a general contractor should be able to speak fluently about GAF shingles and Kohler fixtures in the same conversation. That’s why Costa Mesa customers hire us for projects that span from roof to pavers.
Styles & brands we work with







Licensed General Contractor in Costa Mesa
A Licensed General Contractor in Costa Mesa is the only professional you should trust to pull permits, manage trade sequencing, and own the liability on a residential remodel or addition. The city requires permits for plumbing, electrical, structural, and any second-story work, and an unlicensed handyman puts you at risk of code violations, voided insurance, and resale problems down the line. On a 1970s tract home in 92626, that often means addressing hidden aluminum wiring or polybutylene plumbing before finish work starts.
For Costa Mesa homeowners in the 92626 tract neighborhoods, a typical kitchen remodel runs $14,000 – $45,000, while a bathroom remodel lands between $9,000 – $28,000. A home addition on one of these small infill lots starts around $45,000 and can reach $130,000 depending on whether you’re going up or out.
Permit and Inspection Management
We pull every permit ourselves and coordinate each inspection with Costa Mesa’s building department. You won’t stand in line at City Hall or chase down inspectors. Every change order gets documented in writing, and we file the paper trail that keeps your builder warranty intact where it applies.
Aluminum Wiring and Polybutylene Remediation
Opening a wall on a 1960s-70s tract home often reveals wiring and plumbing that was code at the time but isn’t now. We scope for it before demo starts, then quote the fix separately so it doesn’t ambush you mid-project.
Residential General Contractor in Costa Mesa
A Residential General Contractor in Costa Mesa handles the entire scope of single-family work: kitchens, baths, whole-home remodels, second-story additions, and garage conversions. If you live in a 1960s-70s tract home in 92626 or an older beach bungalow in 92627, the right contractor is the one who knows what’s behind your particular walls before the first hammer swing. We manage the full timeline, from initial design review to final inspection.
Cabinet installation on its own runs $4,000 – $13,000 in Costa Mesa, while countertop installation falls between $2,000 – $6,500. If you’re doing both as part of a full kitchen remodel, you’re looking at the $14,000 – $45,000 range with everything scoped, permitted, and sequenced.
Whole-Home Scope Management
One of the least talked-about frustrations with remodeling is the subcontractor shuffle: the tile guy’s schedule doesn’t line up with the cabinet installer, and you’re the one making phone calls. We carry the schedule. Every trade reports to us, and you get one point of contact through rough-in, finish, and punch list.
ADU and Garage Conversion Feasibility
We assess lot constraints, alley access, and setback requirements specific to Costa Mesa’s tight parcels before recommending whether to build up, out, or convert existing square footage. You’ll know whether an ADU or garage conversion makes sense on your lot before you spend money on design work.
Common General Contractor Problems We See in Costa Mesa Homes
- Aluminum branch wiring hidden behind original drywall. In 92626 tract homes, original aluminum wiring spliced to copper is a fire hazard we find constantly. Rewiring adds cost but must be done with permits, or the builder warranty and your insurance are at risk.
- Polybutylene plumbing ready to fail. Many late-60s and 70s homes in Costa Mesa still have polybutylene supply lines that can burst. We recommend replacing them whenever walls are open for a kitchen or bath remodel.
- Unpermitted enclosed porches and garage conversions. The Westside’s older bungalows often hide rooms that were never legalized. We handle the permit legalization process so you don’t inherit a title issue when you sell.
- HOA design review delays. Newer master-planned communities in Costa Mesa require architectural committee sign-off before installing a fence, paver driveway, or patio. We build that timeline into the schedule from day one so your project doesn’t stall mid-demo.

FAQs About General Contractor in Costa Mesa
The short answer: use a licensed contractor who pulls permits and documents every change in writing. Builder warranties typically stay intact if the work is permitted, inspected, and done by a licensed professional. What voids them is unpermitted work or an unlicensed handyman cutting into structural or electrical systems. We handle the permit paperwork and keep a paper trail so your warranty stays valid. Call (855) 473-5620 to talk through your specific home and warranty terms.
Kitchen remodels are number one, typically $14,000 – $45,000, followed by bathroom remodels at $9,000 – $28,000. After that, homeowners replace original aluminum wiring and polybutylene plumbing once walls are open, since it’s more cost-effective to do it then than later. Countertop upgrades to Cambria or Silestone run $2,000 – $6,500. Call (855) 473-5620 for a free estimate on your specific project.
Yes, most master-planned communities in Costa Mesa require HOA architectural review before hardscape work. The timeline varies by association, typically two to eight weeks. We handle the submittal and manage your project schedule around the review so you’re not left with a torn-up driveway waiting on a stamp. Call (855) 473-5620 and we’ll tell you what your specific HOA requires.
Expect hidden wiring and plumbing issues. Most 1970s tract homes in 92626 have original aluminum branch wiring and polybutylene supply lines. A wall inspection before demo catches these, and we quote remediation separately so you’re not surprised mid-project. The finish work, KraftMaid cabinets and Cambria countertops included, proceeds after the electrical and plumbing are code-compliant. Call (855) 473-5620 to schedule a walkthrough.
Hire someone who pulls permits as standard practice, not as an upcharge. Costa Mesa’s building department requires permits for structural, plumbing, and electrical work on additions, and inspections happen at multiple stages. We manage every submittal and inspection date, and we won’t start work without the permit in hand. Call (855) 473-5620 to discuss your addition and the specific permits it will need.
