Fast, Reliable General Contractor Across Costa Mesa
Finding a General Contractor who understands Costa Mesa’s split personality is harder than most homeowners expect. The 92627 side is a warren of 1950s and 60s tract homes where every wall hides a surprise, and the 92626 side carries its own commercial and multifamily demands. We work both sides of the 55 every week, and we know what permits, inspections, and plan-check paths apply where. If you’re planning a remodel, addition, or full renovation in Costa Mesa, call (833) 382-8544 and we’ll walk the project with you before you commit to anything.
Why Gold Star Contractors Is Costa Mesa’s Preferred General Contractor Company
Homeowners in Costa Mesa hire us because we already know what their block throws at a contractor. We have pulled permits through Costa Mesa’s Building Division on Eastside tear-downs, Westside duplex remodels, and Mesa Verde ranch expansions. The city’s residential parking overlay is real, and our crews arrive with a staging plan before a single board comes off the truck. That matters when a narrow street off 19th Street can get a job red-tagged mid-permit for blocking the wrong driveway.
Noel Carranza runs our Costa Mesa projects with a simple rule: inspect first, price second, and never let a surprise become an argument. Clients on the Eastside and Westside consistently tell us the same thing: the written line-item quote we gave them at the start matched the final invoice because the allowances were realistic, not lowballed. That reputation is built one permit sign-off and one passed inspection at a time.
Styles & brands we work with







Construction Company in Costa Mesa
As a Construction Company in Costa Mesa, we handle the full build, from foundation to finish, on residential additions, garage conversions, and new structures. Costa Mesa’s mix of 1950s small-lot homes and 1970s Mesa Verde ranches means structural work almost always involves working around existing conditions rather than starting clean. A typical home addition in Costa Mesa runs $45,000 – $130,000 depending on square footage, foundation work, and the level of finish you select.
Additions and Structural Work
On a 1950s Eastside tract home off 19th Street, our crew opened a kitchen wall for an addition tie-in and found cloth-wrapped wiring and undersized 2×4 framing that a previous remodel had notched badly. That discovery changed the scope: the permit triggered a full electrical rough-in upgrade and a load-bearing header replacement. We priced the change order in writing before touching it, and the inspection sign-off cleared the way for new KraftMaid cabinets and a Cambria countertop.
Garage Conversions
Costa Mesa’s alley-facing garages on the Eastside create framing and access challenges most contractors never see in newer Inland Empire tracts. We engineer the floor, insulation, and egress to current code rather than just drywalling over the old slab. Garage conversions in Costa Mesa typically run $30,000 – $80,000.
Remodeling Contractor in Costa Mesa
As a Remodeling Contractor in Costa Mesa, we operate inside walls that are 60 to 70 years old, and we plan for what that means before we swing a hammer. A kitchen remodel in Costa Mesa runs $14,000 – $45,000; a bathroom remodel runs $9,000 – $28,000. Those ranges assume we may need to replace galvanized supply lines, add GFCI protection, and reframe openings that original tract builders cut to the bare minimum.
Kitchen Remodels
We specify cabinetry from KraftMaid and Wellborn, and countertops from Cambria, Caesarstone, or Silestone, so you are choosing materials with real installation standards attached. The Costa Mesa building stock we work in rarely has square walls, so our cabinet install includes shimming, scribing, and adjustment that a flat-rate crew from out of town will skip. You see the difference in drawer alignment and countertop seams.
Bathroom Remodels
Original Costa Mesa bathrooms are tight, often 5×8 with a cast iron tub and a single vanity. When we open those walls, we routinely find corroded galvanized pipe and rot at the shower valve. We spec fixtures from Kohler, Grohe, and Moen, and we waterproof with Schluter systems so the tile work survives salt air and daily steam.
Trusted Brands We Service in Costa Mesa
Costa Mesa homeowners care about materials, and we carry the local inventory and install expertise to match. We install Therma-Tru entry doors on Eastside remodels where the original 1950s slab door has warped in coastal air. We work with ViewLux window systems on Mesa Verde homes replacing failed aluminum sliders, and we use Barrette and Master Halco fencing products on Westside lot-line replacements. When you choose a brand from our portfolio, we stock the trim, hardware, and flashing locally so a Costa Mesa job does not stall waiting on parts.

AfterCommon General Contractor Problems We See in Costa Mesa Homes
- Outdated wiring behind original drywall. 1950s and 60s tract homes on the Eastside and Westside still have cloth-wrapped or two-wire circuits. Opening a wall for a remodel triggers a code upgrade, and we write that allowance into the contract up front so it is not a surprise.
- Undersized framing and notched joists. Original Costa Mesa tract framing was built to bare minimums, and decades of remodels have left notched joists and compromised headers. We inspect the framing path before we quote so the structural fix is part of the plan, not a change order after demo.
- Coastal moisture damage at fascia and window trim. Salt air off the Pacific accelerates dry rot at fascia boards, window trim, and door thresholds in Costa Mesa more than inland cities. We check exterior penetrations during every interior remodel because water follows the path of least resistance.
- Parking overlay staging problems. Costa Mesa’s residential parking overlay means a dumpster or concrete truck placed on the street without an encroachment permit can get your job red-tagged. We file the permit and include the staging site on the job plan before any delivery lands on your block.
