Construction Services in Westminster, CA
If you own a home in Westminster, construction pricing here doesn’t work the way it does in Irvine or Newport. Our crews are in Westminster every week, and we answer the phone at (877) 610-1318. You’ll reach a live person, not a voicemail box, and Tom Barrett’s name, address, and license number are published for anyone to verify before signing a contract.
Most Westminster homeowners who call us have already been through it once: a national company quoted a number on the phone, then handed them a different bill at the door. That doesn’t happen with Barrett & Sons. Every scope, every allowance, every price change arrives as a written change order before work happens. An allowance that isn’t on paper is a surprise waiting for a date.

Why Westminster Homeowners Choose Barrett & Sons Construction
We’ve been owner-operated since 1998. Tom Barrett’s sons run the crews, and background-checked, uniformed crew members carry the Barrett & Sons name on every visit. You won’t get a franchise dispatching strangers to your door. You’ll get the same faces showing up each day until the job is finished, and if something isn’t done right, one call brings Tom back. That’s the 90-Day Done Right Promise, written on every contract, not buried in fine print.
Homeowners along Bolsa Chica Road and in the neighborhoods near Westminster Boulevard call us for the same reason the folks in the tracts off Edwards Street do: the permit inspector works for you, not for us. That’s why we like him. Permits get pulled and inspections get signed on every eligible job, because the last contractor most of our customers used told them permits were optional. We don’t play that game.
Westminster homeowners looking at kitchen remodels, bathroom remodels, roofing, windows and doors, fence installation, driveway and pavers, or home additions and ADUs can find exactly one phone number to call. Ours. And we answer it.
Construction Services We Offer in Westminster
Kitchen Remodeling
Kitchen Remodeling - Westminster starts with a written scope, written allowances, and a fixed price. You’ll pick from brands like KraftMaid and Cambria, and you’ll know what every cabinet box, countertop slab, and fixture costs before we order it.
Learn more about our Kitchen Remodeling in Westminster.

Bathroom Remodeling
Westminster’s slab-on-grade ranch homes need careful plumbing planning when Bathroom Remodeling - Westminster moves or expands. We handle the concrete cutting, re-piping, and waterproofing the same crew from tear-out to tile.

Roofing
The marine layer that hangs over Westminster for half the year means moss, moisture, and early roof wear in ways inland cities never see, which is why our Roofing in Westminster addresses these conditions specifically. We install GAF and CertainTeed systems with written warranties, and we pull permits on every tear-off. Roof work means heights and tear-off hazards, so we handle it with full safety gear and trained crews; if you suspect a problem, don’t climb up there yourself. Call us to inspect it instead.

Windows & Doors
We install Windows & Doors in Westminster using Simonton, Ply Gem, PGT, and CGI products with framing corrections where older tract homes have settled. A new window that doesn’t address the surrounding framing won’t seal, won’t operate, and won’t last.
Learn more about our home window and door services.

Fence Installation
Most of our Westminster fence estimates start with the property line and the neighbor conversation. We build wood and vinyl fences on concrete footings that handle Westminster’s flat, occasionally saturated soils without heaving.
Learn more about our home fence installation options.

Driveway & Pavers
Westminster’s flat alluvial ground compacts differently than the hillside terrain in other Orange County cities. We test, compact, and grade before the first paver goes down, using Belgard and Techo-Bloc products with edge restraints rated for vehicle loads.
Learn more about our home driveway and paver services.

Home Additions & ADU
Westminster’s single-story ranch homes, most built between the 1950s and mid-1970s, are increasingly being expanded for multigenerational households. We scope second-story pop-ups, room additions, and ADUs with complete permit packages and structural engineering.

Why Westminster’s Climate & Housing Affect Construction
Westminster sits roughly 7 to 10 miles from the Pacific on the Santa Ana River coastal plain. That means a persistent marine layer that pushes morning moisture deep into the workday. Concrete poured in Westminster cures on a different schedule than concrete poured in Yorba Linda. We plan exterior finishes around that marine layer, and we test flat alluvial soils before any ground-up slab pour, because the compaction characteristics here are different from what contractors encounter in the inland cities. A driveway or ADU slab that fails a compaction test is a five-figure fix later, so we test before we pour.
The city’s housing stock also drives a remodel pattern you won’t see at the same scale in nearby Huntington Beach or Fountain Valley. Westminster’s tract ranch homes are being expanded and reconfigured, not torn down, as multigenerational Vietnamese-American families add rooms, lift roofs, and build ADUs to keep parents and grandparents under one roof. That means the jobs we bid in Westminster often involve structural work, seismic upgrades, and permit scopes that a simple remodel elsewhere wouldn’t trigger.
Pricing for Construction in Westminster
Here’s what we tell Westminster homeowners, straight: a small bathroom remodel might run $18,000 to $30,000. A full kitchen with mid-range cabinets and stone counters usually lands between $35,000 and $60,000. A standard re-roof on a 1,200-square-foot ranch sits around $9,000 to $15,000. Room additions and ADUs start around $200 per square foot and go up based on structural requirements and finish level. Every number assumes permits are pulled and inspections are signed, because our prices include both.
We offer $40 off any repair over $200, a free second opinion on any written estimate, and no trip charge inside the county. Seniors and veterans receive a permanent 10% discount.

FAQs About Construction in Westminster
A kitchen remodel in Westminster typically runs $35,000 to $60,000 for a full renovation with mid-range cabinets and stone counters.

Yes. We pull permits and schedule inspections on every eligible job in Westminster. The permit inspector works for you, not for us, and that’s exactly why we like having the city involved. It protects your investment and keeps the work legal.
No, not unless you change the scope. Every price change arrives as a written change order before a single nail moves. If the allowance wasn’t put on paper at the start, we won’t spring it on you at the end. That’s the whole point of writing everything down.
Yes, weekly. Westminster’s 1950s and 1960s concrete-slab ranch homes are exactly the kind of homes we remodel most. We understand the framing, the plumbing layouts, and the soil conditions in 92683, 92684, and 92685, and we plan for them from the first estimate.
Most room additions and ADU projects in Westminster take three to six months from permit approval to final inspection. The timeline depends on structural engineering, city plan check, and finish selections. Call (877) 610-1318 for a realistic timeline on your specific project, and we’ll walk you through it. Estimates are free.

What Westminster Customers Say
"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"Full kitchen down to the studs. He found the previous owner had done the wiring himself and it was genuinely dangerous, showed me, and put it right properly rather than boxing it back in."
- Augustus Nwachukwu"He pulled every permit and had every inspection signed off. The last contractor we used told us permits were optional and I have been paying for that ever since."
- Redmond Cavanaugh
