If you own a home in Westmont, you’ve probably dealt with the county’s permitting process at some point, or inherited a house with work that never went through it. That’s the reality of an unincorporated community where permits run through LA County Public Works, not LADBS. We’re Barrett & Sons Construction, and we work in Westmont every week, so we know which forms your ADU needs, which inspector covers 90047, and why your stucco bungalow’s slab moves the way it does. If you have a question about a remodel, a roof, or an addition, call (877) 610-1318 and a live person picks up.

Why Westmont Homeowners Choose Barrett & Sons Construction
Tom Barrett started this company in 1998 and his sons run the crews. When you hire us, the name on the truck is the name on the contract, and the man who signs it lives twenty minutes from your street. Homeowners in the blocks around Normandie Avenue and Century Boulevard have called us after a national company quoted one number on the phone and showed up with another. That doesn’t happen here. Every change order goes in writing before a nail moves, and the 90-Day Done Right Promise is written on every contract: if something’s not right, one call brings Tom back.
We’ve worked on homes near the Westmont Recreation Center and throughout the smaller side streets off West 95th and West 108th. The reviews from Westmont homeowners mention two things consistently: the crew shows up when we say they will, and the permit inspector leaves with a signature instead of a headache. Tom publishes his name, his address, and his license number. Look them up before you sign anything. Then call (877) 610-1318 and ask for him directly.
Construction Services We Offer in Westmont
Kitchen Remodeling
Most Westmont kitchens sit in homes built between 1948 and 1962, which means small footprints, load-bearing walls where you don’t expect them, and plumbing that hasn’t moved in sixty years. Our Kitchen Remodeling - Westmont team designs around what’s there. We design around what’s there and carry KraftMaid and Cambria so you know exactly what’s going in.
Learn more about our Kitchen Remodeling in Westmont.
Bathroom Remodeling
Bathroom Remodeling - Westmont projects often involve tight spaces and cast-iron waste lines under the slab that are still original. We’ve done enough of them to price the work honestly before we open the floor, not after.

Roofing
Westmont’s flat-roof and low-slope homes bake through the South LA summers. Our Westmont Roofing crews install GAF and CertainTeed systems rated for that heat, and we pull the County permit before the first shingle comes off.

Windows & Doors
Original single-pane Windows & Doors in Westmont are common on stucco homes, and they leak air all year. We install Andersen and Marvin, and we size replacements to the County’s egress codes so the inspection passes the first time.
Fence Installation
Small lots mean shared property lines and neighbors close enough to hear your plans before you make them. We confirm lot lines, handle the notice, and set posts deep enough for the clay soil’s seasonal heave.
Driveway & Pavers
The expansive clay under Westmont cracks concrete driveways in predictable patterns each winter. We pull and re-pour with proper base prep, and we install Belgard and Techo-Bloc pavers for homeowners who want something that flexes instead of fractures.
Home Additions & ADU
Westmont’s R-2 lots often have unpermitted rear units, and legalizing or rebuilding one under California’s ADU rules means the project lands in LA County’s unincorporated plan check queue. We know that queue. We file the right forms the first time.
Neighborhoods We Serve in Westmont
Our crews work throughout 90047 on a regular basis. We’re already familiar with the streets, the setbacks, and the inspectors who cover them, which saves you time when the project starts.
- The blocks around Westmont Recreation Center
- The residential streets off West 108th Boulevard
- The homes near the 105 Freeway and Normandie Avenue
- The small-lot bungalow rows south of Century Boulevard
- The duplex and triplex streets off Vermont Avenue
For most Westmont jobs, we can have Tom or one of his sons at your door to walk the property within a few days of your call. Bigger projects may take a little longer to schedule, but the plant visit itself is free, and so is the written estimate.
Why Westmont’s Climate & Housing Affect Construction
Westmont sits in the South LA basin on expansive clay soil, and that one fact shapes more construction decisions here than any design magazine ever will. The clay swells when winter rains soak it and shrinks through the long dry summer, which is why slab foundations in 90047 develop hairline cracks and why driveway concrete shifts over time. A remodel that doesn’t account for that movement will fail at the joints within a few seasons. We see it on bungalows near the 105 Freeway and on the duplexes off Vermont, where original slabs from the 1950s are still doing exactly what clay soil makes them do.
The housing stock compounds it. Most Westmont homes are wood-frame stucco built between the late 1940s and early 1960s, and plenty of them carry unpermitted additions or garage conversions from decades past. The moment you pull a County permit for a kitchen remodel or an ADU legalization, LA County’s plan check starts looking at everything connected to it, including work that was never signed off. A contractor who doesn’t know that will get your project stuck for months. We expect it on day one and plan the scope around it.

FAQs About Construction in Westmont
Most kitchen remodels in Westmont run between $38,000 and $75,000 with Barrett & Sons, depending on whether you’re keeping the existing footprint or moving walls. The final price is locked in as a written line-item scope before work begins. Call (877) 610-1318 for an exact quote on your home, estimates are free.
Yes, and because Westmont is unincorporated, your ADU permit comes from LA County Department of Public Works, not LADBS. If you’re legalizing an existing unpermitted rear unit, the plan check will review the entire property. We handle the County forms and the inspection scheduling from first filing to final sign-off. Call (877) 610-1318 and tell us what’s on your lot, we’ll walk you through what the County will look at.
The price changes only if the scope changes, and a scope change gets a written change order before any additional work happens. You see the number in writing, you approve it in writing, then we proceed. There are no surprise invoices at the end. That’s the way Tom has run Barrett & Sons since 1998.
Westmont sits on expansive clay soil that shrinks during the dry summer and swells when winter rain re-saturates it, and the slab foundations poured in the 1950s move with that cycle. It’s a site condition specific to this part of the basin, and it affects driveway flatwork and foundation work alike. We account for it in every estimate. Call (877) 610-1318 for a free assessment of your foundation or driveway.
Most Westmont bathroom remodels take two to four weeks depending on waterproofing scope and whether we’re replacing the cast-iron waste line under the slab. Since permits run through LA County, inspection scheduling can add a few days at each stage, and we build that into the timeline from the start. Call (877) 610-1318 for a schedule based on your specific project.

"Every change to the price came as a written change order before the work happened, not as a surprise on the final bill. I did not know contractors still did that."

- Rosalie Pemberton"Came back a year later to sort a door that had dropped as the frame settled. No charge and no argument about whether it was covered."
