Call (936) 259-2607

We serve all of Westmont, from the neighborhoods along Vermont Avenue to the streets near the Westmont/Athens boundary. Our background-checked, uniformed technicians know what’s behind these walls because we’ve opened enough of them to know exactly what to expect. That local knowledge changes how we bid, how we schedule, and how we protect you from the surprises other contractors find too late.

Why Penhallow Remodeling Is Westmont’s Preferred General Contractor Company

Westmont homeowners have been burned before. They’ve had contractors disappear after demo day, prices that ballooned mid-project, and repairs that failed weeks later. That’s why our approach feels different the first time you call: a real person picks up, we give you a written price before any work begins, and every job carries the 365-Day Done Right Promise in writing. If something fails inside that guarantee period, we come back and fix it at no charge. No service call fee, no re-inspection fee, no argument.

Trevor Nash runs our Westmont operations, and he’s the person who reviews every written quote before it reaches you. Our Westmont customers regularly tell us the same three things: the price didn’t move, the crew showed up in the window we gave, and the job site was cleaner when we left than when we arrived. That’s the Kingswell standard we’ve operated under since 2004, and it applies to every Kitchen Remodeling in Westmont, bath, and whole-home remodel we take on.

When you schedule with us, you know exactly who’s walking into your home. Uniformed, background-checked technicians on every job. A clean, protected work area. And a project lead who explains what “substrate” means the same way they explain what the county plan-check flagged. No jargon left unexplained, no pressure, no false urgency.

Remodeling Contractor in Westmont

Remodeling Contractor work in Westmont is rarely just cosmetic. The homes here, most built between the late 1940s and early 1960s, hide aluminum branch wiring, undersized headers, and failed waterproofing behind stucco walls that look perfectly fine from the street. A Westmont remodel typically costs $14,000 – $45,000 for a kitchen or $9,000 – $28,000 for a bathroom, but those numbers move based on what we find when the walls come open. That’s why we start with an inspection and build written allowances into the contract, so you know what a potential change order could cost before we ever swing a hammer.

What We Inspect First

Before we bid any Westmont remodel, we walk the entire house, not just the room you want done. We look for unpermitted garage conversions, enclosed patios that became living space, and any sign of past electrical or plumbing work that never got a county sign-off. That walkthrough informs every number in your written quote.

Written Allowances for What We Can’t See

We can’t see inside your walls until we open them. What we can do is write allowances into the contract that reflect what Westmont homes reliably contain: aluminum wiring that needs replacement, framing that needs reinforcement, and waterproofing that failed years ago. That way, if we find it, you already know the range. Nothing changes without your written approval.

Licensed General Contractor in Westmont

Licensed General Contractor work in Westmont means navigating LA County’s Department of Public Works and Building & Safety, not a municipal building department. Westmont is unincorporated, so every permit, plan-check comment, and final inspection runs through the county system. That’s a meaningfully different process than neighboring Inglewood or Hawthorne, and contractors who don’t understand the difference lose weeks to county-specific plan-check comments they never saw coming. We know the county process because we work within it every week, and we sequence our inspections to match the draw schedule so your project clears on the first sign-off.

Permit History Research Before the Bid

The first step for any General Contractor bidding a Westmont job is pulling the county permit history on the property. This catches unpermitted additions, conversions, and enclosures before they become a surprise during plan-check. We do this research on every project, and it’s built into our process, not billed as a separate line item.

County Plan-Check Sequencing

LA County’s plan-check timeline runs slower than most incorporated cities, and the comments come back with county-specific code references. We read the plans ourselves, respond to comments in writing, and schedule our inspections to match your payment draws. That keeps the job moving and the punch list short.

Trusted Brands We Service in Westmont

We spec materials from brands that support their own work with warranties, so the products behind our guarantee are as solid as the promise itself. On Westmont kitchens we regularly install KraftMaid and Wellborn cabinetry with Cambria or Silestone countertops, and in bathrooms you’ll find Kohler and Moen fixtures. The same goes for whole-home and addition work: James Hardie siding, Therma-Tru doors, and Belgard pavers for patios and walkways. We stock the common replacement parts locally, which means faster turnaround on punch-list items and less waiting when a fixture fails inside the warranty window. Our relationships with these manufacturers also mean we can pull product specs quickly when LA County plan-check wants documentation.

Common General Contractor Problems We See in Westmont Homes

• Unpermitted garage conversions and patio enclosures. Westmont has no city code-enforcement department of its own, and county enforcement has historically been lighter here than in adjacent incorporated cities. That means a significant share of local homes carry decades-old unpermitted work that surfaces the moment a county permit is pulled.
• Aluminum branch wiring from the original build. Most Westmont homes were built between the late 1940s and early 1960s, when aluminum wiring was common. It’s a known fire hazard and a county flag once walls are opened, which means a modest remodel can trigger a whole-home rewire upgrade if it wasn’t anticipated in the bid.
• Failed flat-roof waterproofing and thermal cycling damage. Westmont sits far enough inland that summer afternoons run 10 – 15°F hotter than Hawthorne or El Segundo. That heat accelerates expansion and contraction in aging stucco and flat-roof assemblies, and we find cracked, failed waterproofing on a majority of the older homes we open up.
• Undersized headers and load-bearing walls that were removed decades ago. Post-WWII framing standards were different, and years of informal modifications have left some Westmont homes structurally compromised in ways a visual walkthrough won’t catch. We document what we find, price the correction, and get your written sign-off before touching the structure.
