Fast, Reliable Bathroom Remodeling Across Westmont
A full bathroom remodel in Westmont typically costs $9,000 to $28,000, and most jobs take two to five weeks once permits clear and materials land. If you live in the 90047 ZIP and you’re planning a walk-in shower, a tub-to-shower conversion, or a full gut, call Barrett & Sons Construction at (877) 610-1318. We know how LA County Public Works permitting works in Westmont, which is a different animal from City of LA plan check, and we’ll tell you the truth about what your older bungalow is likely to hide before you sign anything.
Why Barrett & Sons Construction Is Westmont’s Preferred Bathroom Remodeling Company
Tom Barrett founded this company in 1998, and his sons still run the crews that work in Westmont. That means the name on the contract is the name on the truck, and the person answering the phone lives the same way you do: one wrong change order away from a conversation at the hardware store they’d rather not have. Our Bathroom Remodeling team pulls permits through LA County Public Works on every eligible Westmont job, and when the County inspector walks your property, we want him to see exactly what was approved on paper.
Westmont homeowners between 50 and 70 have told us the same story for almost three decades: a national outfit quoted one number on the phone, then found “unforeseen conditions” once the wall came down and handed over a bill that looked nothing like the estimate. We do it differently. Every allowance is written into the contract before demolition starts, and every price change arrives as a written change order before work proceeds. That’s not a promise Tom makes in a sales pitch. It’s printed on every contract we sign.
Response time to Westmont matters because when your only bathroom is gutted, three extra weeks is a disaster. Our crews work Westmont jobs on schedules built around your household, and Tom has been known to drive twenty minutes from the metro office to walk a job the same day a homeowner calls with a concern. We carry the brands you can look up: Simonton and Ply Gem in windows and doors that often accompany a bathroom-to-suite remodel, and PGT where impact-rated glazing is called for. You won’t find mystery materials off a van on our jobs.
Our Bathroom Remodeling Services in Westmont
We don’t take a bathroom down to studs and then ask you what you wanted. Before any work starts on a Westmont remodel, we walk the existing space, check what’s behind the walls where we can, and write the scope in plain English with real allowances. These are the services Westmont homeowners call us for most.
Walk-In Showers & Shower Remodeling
Westmont’s postwar bungalows were built when a 5-foot tub was the standard, and that tub now eats half the room while nobody in the house takes baths anymore. A walk-in shower remodel in Westmont typically runs $4,500 to $12,000 depending on tile, glass, and what we find behind the wall. The big variables here are waterproofing failure and subfloor condition, both of which we cover below under pricing.

Tub-to-Shower Conversion
For the smaller bathrooms in Westmont duplexes and postwar stucco homes, a tub-to-shower conversion is often the single best move: it opens up floor space, removes a trip hazard for older household members, and costs less than a full gut. In Westmont, conversions run $3,500 to $10,000. The job usually includes pulling the old tub, replacing the drain and trap, waterproofing, and installing a curb or curbless shower pan plus surround and glass.

Vanities, Tile & Fixtures
Sometimes the bones of a bathroom are fine and the problem is a vanity that’s falling apart, tile that’s lost its grout, and fixtures from the Nixon administration. A vanity install in Westmont runs $800 to $3,000 including plumbing adjustments and disposal. Tile work depends on square footage and material: we bring actual samples from local suppliers to your door, not a catalog page. And every fixture we install comes with a written warranty from the manufacturer, so when a cartridge fails in year three, you know who answers the phone.

Small Bathroom Remodels
Westmont’s half-bath and guest-bath situations are common in the small-lot duplex stock across the 90047 ZIP. These run $5,000 to $12,000 and almost always include an upgrade to the existing lighting circuit, which is a County inspection item that catches off-guard contractors. We plan for it in the bid, which is why our small bathroom remodels don’t stall at rough-in waiting for an electrician to be found.

Trusted Brands We Service in Westmont
We install and service materials from brands you can actually read about: Simonton windows, Ply Gem product lines, and PGT impact-rated glazing on projects where Westmont’s sun and heat demand it. Because we’re doing bathroom-to-suite remodels across View Park-Windsor Hills, West Athens, and Inglewood too, we keep our Westmont crews stocked with the trim, clips, and hardware these systems need, so a missing shower glass clip doesn’t mean a two-week stall. If you know the brand you want, say so; if you don’t, we’ll show you named options with real prices, not “upgraded materials” with no name attached.
Common Bathroom Remodeling Problems We See in Westmont Homes
If we could hand a Westmont homeowner one piece of paper before they ever sign a bathroom remodel contract, it would be this list. Every one of these is real, and every one changes the price.
- Code-triggered upgrades eat the budget. Open a wall in a 1950s Westmont bungalow and you’ll often find corroded galvanized supply lines or wiring that no inspector will sign off on. When the permit rides through LA County Public Works, the inspector can require an electrical rough-in upgrade or a plumbing repipe before we close the wall. Our contract includes a written allowance for exactly this, so the change order gets approved on-site, not sprung on you later.
- Unpermitted prior work surfaces at rough-in. A garage conversion or an added bathroom that was never approved by the County forces a compliance review when the permit is pulled. Crews who don’t know unincorporated plan check get stuck in a queue unfamiliar to them; we know the forms, the setback tables, and the inspector’s expectations in Westmont before the job ever starts.
- Slab heave cracks the subfloor. Expansive clay soil under Westmont’s postwar slab foundations moves seasonally: it dries and contracts through the long rainless summers, then re-saturates in winter. By the time you renovate a bathroom, the tile may have been hiding cracks and the toilet flange may no longer sit level. If the subfloor has moved, we address it in the written scope, not after demolition.
- Bathrooms out of service longer than promised. In small Westmont homes, especially duplexes with one bath, a remodel that drags six extra weeks is a crisis. We sequence the work so the bathroom is out of service for the shortest possible window, and we’ll tell you during the estimate exactly when water returns to the room and when you can shower.

FAQs - Bathroom Remodeling in Westmont
No. Westmont is an unincorporated community governed by Los Angeles County, so bathroom remodel permits, inspections, and code enforcement run through the LA County Department of Public Works, not LADBS. Any bathroom remodel that changes plumbing, electrical, or structural elements requires a County permit, and we pull it for you on every eligible job. The inspector works for you, not for us, which is exactly why we like him there.
If a previous owner added a bath, converted a garage, or moved plumbing without County approval, that unpermitted work becomes visible during a permitted remodel, and LA County can require a compliance review before inspections sign off. In a Westmont remodel, we find this often: the small R-2 lots and the age of the housing stock made unpermitted rear-unit conversions extremely common. When it happens, the project lands in the unincorporated plan check queue, not the City’s, and we handle the forms, setbacks, and inspection workflow so your project doesn’t stall for weeks. Call (877) 610-1318 and we’ll talk through what your permit history looks like and what it means for your remodel.
Because older Westmont homes hide code violations and deteriorated materials that no one can see until the wall is open: corroded galvanized pipes, damaged framing, or wiring that fails a County inspection. The difference is in how the contractor handles the discovery. Our contract includes written allowances for code-triggered upgrades, and any change arrives as a written change order approved by you before work proceeds. The price shouldn’t surprise you; the condition of your 1950s plumbing might, but the bill won’t.
Yes, they can. Westmont sits on expansive clay soil that contracts during the long dry summers and swells when winter rains come, which causes slab movement in postwar foundations. By the time we open a bathroom floor, we often find cracked tile, uneven subfloor, or a toilet flange that’s no longer seated. If the slab has moved, it affects the tile and plumbing rough-in, and we’ll show you what we found before we ask for a change order.
Draws follow the work, never the calendar. You pay for what’s been completed, not on a schedule that front-loads the contractor. Inspections happen at the same points every LA County job requires: rough-in for plumbing and electrical, then a final after we finish tile, fixtures, and trim. We’re on-site for every inspection, and the County inspector signs off in the same portal where the permit was pulled. Then we walk the finished room with you before we call the job done. If you have questions about a specific project in the 90047 ZIP, call (877) 610-1318 and ask for a free estimate.
Bathroom remodeling in Westmont means dealing with LA County Public Works, 70-year-old framing, expansive clay soil, and the very real possibility that a previous owner did work they never told anyone about. We’ve handled every one of those on this side of the 110, and we handle them with a contract that puts every allowance in writing and every price change on paper before it happens. Tom Barrett’s name, address, and license number are published and verifiable. Call (877) 610-1318 to schedule your free estimate, and if you have a written bid from anyone else, bring it: we’ll give you a free second opinion and tell you honestly where you stand.
