AfterRemodeling Company in Westmont, CA
Home remodeling in Westmont typically runs $9,000 – $130,000 depending on whether you’re updating a single bathroom or reconfiguring an entire post-war floor plan. We’re Penhallow Remodeling, and we handle the full scope for Westmont homeowners, from kitchen and bath updates to whole-home reconfigurations and garage conversions. Because Westmont sits under LA County jurisdiction rather than its own city government, every permit, inspection, and code review flows through the county’s Department of Public Works and Building & Safety, a process that moves on county timelines with county-specific requirements. Call us at (936) 259-2607 and we’ll walk you through what that means for your specific project before we ever pick up a tool.
Why Westmont Homes Are Different
Westmont’s housing stock was built fast and built similarly, nearly all of it wood-frame stucco construction from the late 1940s through the early 1960s. Seven decades later, that uniformity creates predictable patterns. The same flat-roof assemblies appear block after block. The same original electrical panels hover near capacity. And perhaps most consequentially for today’s homeowner, the same decades of informal additions, garage conversions, and covered-patio enclosures were constructed without county permits, because Westmont has no city code-enforcement department of its own.
That absence matters when you pull a permit for even modest work. LA County’s plan-check process routinely surfaces unpermitted structures that must be legalized retroactively, expanding scope and cost in ways that surprise homeowners and catch out-of-area contractors who’ve never navigated county-specific requirements. Meanwhile, Westmont’s inland location, roughly ten to fifteen degrees hotter on summer afternoons than coastal Hawthorne or El Segundo, accelerates thermal cycling in aging stucco and flat-roof assemblies. California’s Title 24 energy code pushes cool-roof compliance harder here than at the beach, and we size HVAC upgrades accordingly.
Our Main Westmont Services
Most Westmont homeowners who call us start with one of these three projects, each shaped by the local conditions above.
General Contractor in Westmont
As your general contractor, we coordinate every trade, permit, and inspection through LA County’s system, not a city portal. We’ve learned the county’s plan-check timelines and retroactive-legalization triggers the hard way, on actual Westmont jobs where unpermitted 1970s room additions surfaced mid-project. Our crew arrives in uniform, background-checked, and with a written price already in your hand. General Contractor in Westmont covers our full build-management approach.
Bathroom Remodeling in Westmont
Westmont’s original bathrooms are compact, often five-by-eight feet with galvanized supply lines and no exhaust ventilation. We strip to studs, update plumbing to copper or PEX, install proper exhaust fans vented to the exterior (not the attic, where we find mold half the time), and rebuild with moisture-resistant cement board substrate behind every tile surface. Bathroom Remodeling in Westmont details our process.
Kitchen Remodeling in Westmont
These post-war kitchens were designed for one cook, with 36-inch-high counters and 24-inch-deep cabinets that feel cramped by today’s standards. We reconfigure for open flow where structurally possible, run dedicated circuits for modern appliance loads, and specify cabinetry and countertops from recognized trade brands that carry their own warranties alongside our 365-Day Done Right Promise. Kitchen Remodeling in Westmont walks through typical layouts.

Home Remodeling in Westmont
Home remodeling in Westmont means working with LA County’s permitting authority from day one, not a city building department, and it means expecting the unexpected when county plan-check reveals decades-old unpermitted work in a home’s history. We research permit history before we bid, so you’re not blindsided by retroactive legalization costs after demo starts. Whether you’re updating a single room or reconfiguring your entire post-war floor plan, we give you a written price before any work begins and back every project with our 365-Day Done Right Promise. Home Remodeling explains our full-service approach.

Will unpermitted work in my Westmont home affect my remodel?
