Construction Services in Rancho Santa Margarita, CA
If you own a home in Rancho Santa Margarita, you already know the drill: the house is 20 to 35 years old, it sits up against the Santa Ana Mountains, and the next remodel or reroof means dealing with both SAMLARC and California’s Wildland Urban Interface code. Barrett & Sons Construction handles that paperwork and the work itself. Tom Barrett and his sons run the crews, every permit gets pulled, and you’ll get a written change order before any scope change touches your job. Call (877) 610-1318 and a live person answers, day or night.

Why Rancho Santa Margarita Homeowners Choose Barrett & Sons Construction
Most of our Rancho Santa Margarita work comes from referrals in Tijeras Creek and Trabuco Canyon Highlands. The reason isn’t complicated. Tom Barrett publishes his name, his address, and his license number. You can look it up before you sign anything. The crew members on your property carry the Barrett & Sons name, and they’re background-checked and uniformed on every visit. When a homeowner asks us to come back under the 90-Day Done Right Promise, one call brings Tom back, not a phone tree.
A live person answers the phone 24 hours a day, seven days a week. That matters in a community like Rancho Santa Margarita, where homeowners have been burned by national outfits that quote one price and show up with another. We don’t work that way. Scope in writing, allowances in writing, change orders in writing. It’s all there on the contract.
We’re not a franchise dispatching strangers. Tom’s sons run the crews. If you see a Barrett & Sons truck on Antonio Parkway or Santa Margarita Parkway, the person driving it probably lives within twenty minutes of you.
Construction Services We Offer in Rancho Santa Margarita
Kitchen Remodeling
We’ve remodeled dozens of kitchens in the original tract homes here, many of which still have the builder’s oak cabinets and laminate counters from the early 1990s. KraftMaid and Cambria are in our standard material lineups, and every allowance is written into the contract before demo day. Learn more about our Kitchen Remodeling in Rancho Santa Margarita.

Bathroom Remodeling
Original builder bathrooms in Rancho Santa Margarita often hide water damage behind fiberglass tub surrounds we can’t see until demolition starts. Schluter waterproofing under tile is standard on our bathroom remodels, and the permit inspector signs off before the walls close up. Learn more about our Bathroom Remodeling in Rancho Santa Margarita.

Roofing
Roofs on 1990s and early-2000s tract homes here are hitting replacement age, and because most of RSM sits in a CalFire High or Very High Fire Hazard Severity Zone, that means Class A roofing material and ember-resistant vents. We install GAF systems and pull the WUI compliance into the permit application from the start. Learn more about our Roofing in Rancho Santa Margarita.

Windows & Doors
Many original windows in Rancho Santa Margarita are single-pane dual-glazed units that fog between the panes and leak conditioned air. Andersen and Marvin are options we carry, and HOA architectural review in SAMLARC communities often requires specific frame colors and trim profiles before installation. Learn more about our Windows & Doors in Rancho Santa Margarita.

Fence Installation
Hillside lots in Rancho Santa Margarita make fence lines trickier than in flatland Orange County. Expansive clay soil shifts posts, and viewshed rules in some SAMLARC tracts limit fence height and material. We handle the HOA paperwork and build fences that stay plumb through the seasonal ground movement.

Driveway & Pavers
Santa Ana winds and sun beat on concrete flatwork year-round. Belgard and Techo-Bloc pavers hold up better than poured slabs on RSM’s cut-and-fill lots, where drainage has to be graded correctly or water pools against the foundation. Every paver job includes a written base-prep spec before we dig.

Home Additions & ADU
Single-story tract homes in Rancho Santa Margarita often have decent side-yard space for an ADU, but the WUI fire code and SAMLARC’s architectural board both weigh in. We’ve taken additions through dual approval before, and we don’t tell homeowners permits are optional. The permit inspector works for you, not for me. That’s why I like him.

Why Rancho Santa Margarita’s Climate & Housing Affect Construction
Rancho Santa Margarita was built between roughly 1987 and 2005, which means the housing stock is now at the age where roofing, windows, decking, and original stucco all fail around the same time. We see the same original builder components across dozens of nearly identical floor plans: Masonite siding on some 1990s models, single-pane windows, composition shingle roofs. When one house on a Rancho Santa Margarita street needs Rancho Santa Margarita Roofing, the neighbors usually do within a year or two.
Then there’s the wind. RSM sits at the canyon mouth where seasonal Santa Ana winds funnel through each fall. That accelerates stucco cracking, weathers exterior finishes, and shortens roof fastener life. And because most parcels are in a CalFire-designated High or Very High Fire Hazard Severity Zone, any exterior construction triggers WUI compliance requirements. A simple reroof can require ember-resistant vent retrofits and ignition-resistant eave work that a contractor in Mission Viejo’s flatland tracts never has to budget for. If your contractor doesn’t know the FHSZ designation for your parcel, the first surprise comes at the permit counter.

FAQs About Construction in Rancho Santa Margarita
If your home sits within SAMLARC-managed community, most exterior changes do require architectural review board approval before permits are issued. That includes new windows with visible frame changes, reroofs with a different material or color, fence replacements, and any addition or ADU. We prepare and submit the architectural review package with your permit application, so you’re not stuck chasing paperwork alone.
Kitchen Remodeling in Rancho Santa Margarita typically runs between $38,000 and $85,000 depending on cabinet line, counter material, and whether you’re reconfiguring the original 1990s layout. KraftMaid cabinets and Cambria counters cost more than builder-grade replacements, and moving plumbing or electrical adds to the total. Call (877) 610-1318 for a free line-item estimate.
If your property sits in a CalFire High or Very High Fire Hazard Severity Zone, which covers most of Rancho Santa Margarita, exterior work like reroofing, siding replacement, or an ADU will trigger WUI compliance requirements. That means ignition-resistant materials, ember-resistant vents, and possibly eave retrofits. A contractor unfamiliar with the local FHSZ map will miss these line items and surprise you later. We build them into the first estimate.
A live person answers 24/7. Not a voicemail box, not an out-of-state call center. If Tom or his sons are on a Rancho Santa Margarita job, someone still picks up the phone. That’s part of how we operate.
Yes, on every eligible job. Permits pulled and inspections signed. The last contractor most of our Rancho Santa Margarita customers used told them permits were optional. They’re not optional, and the inspector works for you anyway. Call (877) 610-1318 if you want a straight answer before you sign anything.

What Rancho Santa Margarita Customers Say
"The bathroom was finished on the day he said at the start, which nobody had led me to believe was possible."
- Loretta Vanterpool"His sons run the crews and they were in our house for four months. Not once did I feel I had to be home to keep an eye on things."
- Camila Fuentes"Beautiful work and honest pricing throughout. The project ran about three weeks past the estimate waiting on the cabinets, which was the supplier rather than him, though the delay was still real."
- Genevieve Ashcombe
