Why Castaic Homeowners Choose Barrett & Sons Construction
We’re not the biggest name in town and we don’t want to be. Tom Barrett founded this company in 1998, and his sons run the crews that work the neighborhoods around Castaic Lake, Hillgate, and Hasley Canyon. When you call, you talk to someone who knows what a Santa Ana wind event does to a roof edge off Lake Hughes Road, and who knows why retaining walls in the older hillside tracts start leaning after twenty years. Every price change arrives in writing before a single nail moves. Every eligible job has permits pulled and inspections signed. And every completed job carries our written 90-Day Done Right Promise: if it’s not right, one call brings Tom back to make it right.

Windows & Doors
Santa Ana winds rattling your Windows & Doors - Castaic off the I-5 corridor aren’t just noisy; they’re a sign your 25-year-old windows have lost their seal. We install Simonton and Ply Gem products sized correctly for Castaic’s hot, dry exposure.

Fence Installation
The sun and wind out here eat cheap fence posts in five years. We set posts below the hardpan line, use pressure-treated or steel, and build fences that stay straight when the fill settles.

Driveway & Pavers
Castiac’s hillside lots mean drainage and compaction are everything. We install Belgard and Techo-Bloc paver driveways with proper base depth so you don’t get shifting, sinking, or washout after the first winter rain.

Home Additions & ADU
Adding square footage on a hillside pad requires grading, retaining walls, and VHFHSZ-compliant exterior assemblies. We handle the whole package, permits through final inspection, with written change orders at every step.

Why Castaic’s Climate & Housing Affect Construction
Castaic sits at the northern fringe of the Santa Clarita Valley where 1990s and 2000s residential development pushed straight into fire-prone chaparral hillsides. That means nearly every remodel or addition here has to satisfy Los Angeles County’s Very High Fire Hazard Severity Zone standards: Class A roofing, ember-resistant vents, fire-resistant exterior assemblies. Those rules don’t follow you into the flatter parts of Valencia, but they’re a fact of life in Castaic. On top of that, the canyon-edge lots off Lake Hughes Road bring aggressive grading and retaining-wall demands. We regularly find diagonal cracking running from door and window corners on the downhill side of homes, the signature of differential settlement between the cut and fill portions of 1990s-era graded pads. The engineered fill keeps consolidating under the slab long after the original builder warranty is gone.
The climate shapes scheduling too. Summer highs out here routinely pass 105°F, and the I-5 corridor funnels Santa Ana winds hard each fall. We avoid high-heat concrete pours and high-wind framing days because those conditions genuinely compromise the work. A re-roof scheduled during a red flag warning is a re-roof that fails; we’d rather tell you to wait a week than gamble on your house.
Pricing for Construction in Castaic
Honest numbers matter because Castaic homeowners have been burned by national outfits that quote one price on the phone and present another at the door. Here’s what we tell people on the first call:
- Kitchen remodel: $45,000-$95,000 depending on footprint, cabinet line, and whether walls move
- Bathroom remodel: $22,000-$55,000 for a full gut and rebuild
- Roof replacement: $18,000-$38,000 for a Class A VHFHSZ-compliant assembly
- Windows & doors: $900-$1,800 per opening installed, brand and size dependent
- Fence installation: $35-$60 per linear foot installed
- Driveway pavers: $18-$30 per square foot with proper base and compaction
- Home addition / ADU: $275-$450 per square foot all-in with permits
Every estimate is free, line-itemed, and written. Every change order arrives on paper before work proceeds. The allowance that isn’t on paper is a surprise waiting for a date, and we don’t do surprises. Call (877) 610-1318 for an exact quote on your project.

FAQs About Construction in Castaic
Yes. Castaic falls within Los Angeles County’s Very High Fire Hazard Severity Zone, so any roof replacement must meet Class A assembly requirements including ember-resistant vents and appropriate underlayment. We pull the permit and make sure the inspection passes so your insurance stays valid too. Call (877) 610-1318 and we’ll walk you through what your house needs.
Most Castaic homes from the 1990s and 2000s were built on cut-and-fill pads, and the engineered fill continues to settle for decades. Diagonal cracking on the downhill side of the house is a classic sign of differential settlement between the cut and fill portions of the pad. It’s usually not structural doom, but it does need to be assessed before you renovate over it. We’ll tell you honestly what we see and what it means for your remodel budget.
On every eligible job, yes. The permit inspector works for you, not for us, and we like it that way. Anyone who says permits are optional in Castaic is either misinformed or cutting corners at your expense. Our permits are pulled and inspections signed before we call the job done.
Only if the scope changes, and only in writing. You’ll receive a written change order before any scope adjustment touches the job. No surprises at the end, no allowances that mysteriously evaporate. If we find something behind a wall we didn’t plan for, we show you, we discuss it, and we get your written approval before moving forward.
Depends on the job. A roof replacement is typically done in under two weeks. A full kitchen remodel runs six to ten weeks. We’ll give you a written schedule with your estimate and update you if wind events or 105°F days force us to adjust timing. Call (877) 610-1318 and we’ll give you a straight answer for your project’s size.

What Castaic 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."
