Fast, Reliable General Contractor Across Mission Viejo
If you own a home in Mission Viejo built between the late 1960s and early 1980s, you already know the trade-off: great bones, mature landscaping, and floor plans that need updating. Most homeowners searching for a General Contractor in Mission Viejo are planning a kitchen remodel, a bathroom overhaul, a room addition, or an ADU – and the biggest question isn’t whether the project is possible. It’s whether the contractor knows what’s hiding behind the drywall. We do. San Bernardino Contractors has opened enough walls in 92690, 92691, and 92692 to know exactly what a Mission Viejo tract home reveals when the demo starts. Call (855) 473-5620 to schedule your free estimate, and we’ll walk the project with you before any work begins.
Why San Bernardino Contractors Is Mission Viejo’s Preferred General Contractor Company
Mission Viejo isn’t like neighboring newer cities. Homes off La Paz Road, Alicia Parkway, and Marguerite Parkway were built under a different electrical code, with different drainage assumptions, and under HOA covenants that still carry weight today. That’s not a problem if your contractor plans for it. It’s a nightmare if they don’t. Our team pre-inspects for aluminum branch wiring, undersized panels, cast-iron drain lines, and the slope-related drainage issues common on Mission Viejo’s curvilinear lots. We write allowances into the contract before we start, so when a permit triggers a panel upgrade or a framing repair, the cost range is already on the table.
San Bernardino Contractors has built a reputation in Mission Viejo by doing the unglamorous work first: checking what’s in the walls before quoting what goes on top of them. That approach means fewer change-order surprises and fewer disputes after tile is set. Reviews from Mission Viejo customers consistently mention the same things: written change orders, clear communication, and a crew that shows up when they say they will. Led by Ruben Castillo, our team treats every remodel as if we’re working on a neighbor’s home, because in Mission Viejo, that’s often exactly the case.
Styles & brands we work with







General Contractor Services in Mission Viejo
General Contractor Services in Mission Viejo mean something specific here. It’s rarely new construction. It’s taking a 1972 tract home with original floor plans, aluminum wiring in some phases, and a kitchen closed off from the living space, and turning it into a home that works for 2026. A typical kitchen remodel in Mission Viejo runs $14,000 to $45,000, depending on whether you’re keeping the existing footprint or moving walls. A bathroom remodel lands between $9,000 and $28,000. We handle every phase: demolition, framing, electrical, plumbing, tile, cabinetry, and finish work, all under one contract.
Kitchen and Bath Remodels
Most Mission Viejo kitchens we open have good bones but outdated layouts. Removing a load-bearing wall to create an open concept means installing a properly sized beam and header, and that means an engineer’s letter and a city permit. We handle the structural work, the permit package, and the cabinet and countertop installation. You pick the finish level – builder-grade or Cambria quartz. We build to the plan.

Additions and ADUs
Adding square footage in Mission Viejo usually triggers HOA architectural review if you live in a covenant-controlled tract. We prepare the plans, submit the paperwork, and coordinate with the association so you’re not stuck chasing signatures. A home addition in Mission Viejo typically runs $45,000 to $130,000, while ADU construction ranges from $90,000 to $220,000 depending on size and whether you go site-built or prefab.

Construction Company in Mission Viejo
As a full-scope Construction Company serving Mission Viejo, we’re often brought in after another contractor has already made a mess, or after a homeowner has been told something isn’t possible. Our answer is usually different. We recently opened up a kitchen in a 1972 tract home off La Paz and found aluminum branch wiring and a 100-amp panel that couldn’t support the new induction range. Our electrician re-wired the affected circuits with copper and upgraded the panel to 200 amps, and we priced the added work as a written change order before proceeding. The project passed final inspection sign-off without delays, and the homeowner now has a safe, code-compliant kitchen.
Roof replacement in Mission Viejo runs $8,000 to $20,000, and given Santa Ana wind events and the HOA’s fire-resistance expectations, most homeowners opt for GAF or CertainTeed architectural shingles. We’re a General Contractor that handles the roof, the windows, the siding, and the interior in one contract, so you’re not coordinating four crews.
Whole-Home Scope
From the roof down to the pavers, one contractor handles every phase. On a recent Mission Viejo project, we replaced a CertainTeed roof, swapped original aluminum windows for dual-pane units, and re-plumbed a cast-iron drain stack that had been weeping into the subfloor for years. The homeowner didn’t have to call a roofer, a window company, and a plumber separately. We owned the timeline.
Exterior and Hardscape
Mission Viejo’s sloped lots mean drainage and grading aren’t optional. We install pavers, retaining walls, and proper site drainage so winter rains don’t run toward the foundation. Paver patios in Mission Viejo typically run $3,500 to $11,000, and we build them with grades that actually work.
Trusted Brands We Service in Mission Viejo
You pick the brand, we handle the build. We’re authorized to work with 50+ product lines across every trade category, so you’re not stuck with whatever a subcontractor happens to have in the truck. For Mission Viejo remodels, we frequently install Grohe and Sterling fixtures in bathrooms, GAF and CertainTeed roofing on exteriors, and Cambria or Silestone quartz on counters. Because we stock common replacement parts and trim pieces locally for Mission Viejo customers, mid-project changes don’t stall the job for two weeks. If a valve body needs a different finish or a shingle color needs to match an HOA palette, we can usually source it same week. One contractor, every phase, with material accountability that shows up on the punch list.

AfterCommon General Contractor Problems We See in Mission Viejo Homes
We’ve worked enough Mission Viejo homes to know what goes wrong when a contractor isn’t prepared. Here’s what we find, and what we do about it:
- Aluminum branch wiring and undersized panels: In the older tracts off La Paz and Alicia, original aluminum branch wiring is common. When walls open for a remodel, current code often requires re-wiring affected circuits and upgrading the panel before final inspection. We check for this before quoting, not after.
- Cast-iron drains and failed waterproofing: The original cast-iron drain lines under Mission Viejo slabs have a lifespan, and many of them have reached it. If we open a bathroom or kitchen floor and find corroded pipe or water-damaged subfloor, we price the replacement as a written change order before proceeding. No surprises, no finger-pointing.
- HOA architectural review delays: Mission Viejo’s covenant-controlled neighborhoods require design approval before exterior work begins. We know the forms, the submittal process, and what typically gets flagged for paint color, roofing material, or fence height. We handle the paperwork.
- Sloped-lot grading and drainage: The curvilinear street layout that makes Mission Viejo feel so distinctive also creates drainage challenges. When we’re building an addition or hardscape, we check the lot’s existing grade and include proper drainage in the bid. We don’t wait for the first winter rain to find out where the water goes.

FAQs About General Contractor in Mission Viejo
Expect a panel and circuit upgrade to be part of the scope. In the older Mission Viejo tracts, opening walls for a kitchen or bath remodel usually triggers a requirement to re-wire affected circuits with copper and bring the panel up to 200 amps. We check for aluminum wiring before we quote, and we build the upgrade cost into the contract allowance so you see it coming. Call (855) 473-5620 if you want us to inspect your home first.
We price the fix as a written change order, and we don’t proceed until you’ve approved it in writing. Our pre-bid inspection usually catches most issues – water-damaged subfloor, corroded cast-iron drain lines, termite damage – before we start. If something shows up mid-demo that we couldn’t have seen, you get a photo, a specific scope item, and a price. No blank checks. No guessing. Call (855) 473-5620 for a pre-bid inspection on your Mission Viejo home.
Yes, especially in Mission Viejo tract homes built in the 1960s and 70s. When a permit is pulled, the inspector applies current code to the work being done. If the panel is undersized for the new load, if the branch wiring is aluminum, if the framing doesn’t meet current shear requirements, those items go on the correction list. That’s why we write code-upgrade allowances into our Mission Viejo contracts up front. Call (855) 473-5620 to have us walk your project before you commit.
A kitchen remodel in Mission Viejo typically runs $14,000 to $45,000 depending on the finish level, whether you’re moving walls, and whether your home needs an electrical upgrade or drain replacement.

Custom layouts with Cambria or Silestone quartz, Grohe fixtures, and carpentry work land at the upper end. We’ll give you a written line-item breakdown before you sign.
