Remodeling Company in Westmont, CA
Home remodeling in Westmont usually means working inside a house built between the 1940s and 1970s, where original plumbing, wiring, and framing are all reaching the point of needing real attention. We’re Penhallow Remodeling, and we handle kitchen, bathroom, and whole-home remodels across Westmont under one promise: a written price before we start, and a 365-day written guarantee that says if it’s not done right, we come back and make it right. Call (213) 277-6578 for a free estimate on your project.
Why Westmont Homes Are Different
Westmont sits as an unincorporated pocket of Los Angeles County, surrounded by the City of Los Angeles but governed by county codes. That distinction shapes every permit, inspection, and plan check differently than a L.A. city project would. When we remodel a Westmont home, we’re working to Title 26 of the Los Angeles County Building Code, and county inspectors enforce local amendments on additions and ADUs more strictly than many homeowners expect. We pre-check plans against those county amendments before anything gets submitted.
The housing stock compounds the challenge. Most Westmont homes are single-family, mid-century wood-frame construction with stucco exteriors. The original galvanized plumbing is often at the end of its service life, the electrical panels are commonly 60-amp originals, and many foundations show the settling you’d expect from sixty-plus years of Southern California clay soil. A remodel on these houses is never just cosmetic. We account for repiping, rewiring, and structural reinforcement inside the written price, not as change orders after demo day.
Climate matters here too. Westmont gets hot, dry summers and occasional heavy winter rain. That means proper drainage grading, UV-stable exterior materials, and flashing details that hold up to thermal expansion. We’ve seen roof leaks and stucco cracks that trace back to inadequate drainage around the foundation, so we factor grading into the plan rather than patching the symptom.
Styles & brands we work with







Our Main Westmont Services
Most Westmont homeowners call us first about one of three things: a kitchen that no longer works, a bathroom that’s leaking or dated, or a larger whole-home project that needs a general contractor who will keep the county inspections moving. Here’s what each one looks like in Westmont.
General Contractor in Westmont
A general contractor in Westmont has to understand county permitting, aging mid-century framing, and the specific repair work these houses carry with them. We act as the single point of contact for your project, scheduling every trade in sequence, pulling county permits, and keeping the job site clean through the process. Because most Westmont homes were built before current seismic standards, we routinely coordinate shear-wall retrofits and foundation repairs alongside interior work. General Contractor in Westmont details how we run a full project from plan check to final inspection.

Bathroom Remodeling in Westmont
Bathroom remodels in Westmont often reveal galvanized supply lines and cast-iron drains that have been slowly failing behind the walls. We open the wall, show you exactly what’s there, and replace it with PEX and ABS before tile goes up so you don’t pay for a beautiful shower sitting on pipes that leak next year. The county also requires specific plumbing permits and inspections, which we handle from start to finish. Bathroom Remodeling in Westmont walks through pricing and timeline for a typical Westmont bath.

Kitchen Remodeling in Westmont
Westmont kitchens from the 1950s and 60s often have cut-up floor plans, original electrical that can’t support modern appliances, and cabinets built around appliances that no longer exist. We handle the full scope: layout, electrical, plumbing, cabinetry, counters, and the county inspections that come with it. Because these houses sit on clay soil, we also check slab flatness before cabinet installation and level the floors where needed. Kitchen Remodeling in Westmont gives you real numbers for a mid-century kitchen brought current.

Home Remodeling in Westmont

Whole-home remodeling in Westmont means updating a mid-century house to modern standards without gutting the character that made you buy it. The work usually involves a combination of kitchen and bath replacement, electrical and plumbing upgrades, new flooring, and often structural reinforcement for the county’s seismic requirements. Home Remodeling covers the full process from first walkthrough to final walk-through, always with a written price before any demo begins. Here in Westmont, we see the most demand for full home remodels when a family outgrows the original 900 to 1,200 square-foot footprint and needs the existing space to work harder.
