Why Elmstead Remodeling Is Westmont’s Preferred General Contractor Company

Westmont homeowners know their unincorporated status changes everything about how a job gets built. We’ve walked enough County permit paths to know which inspector handles raised-foundation seismic retrofits and how far in advance to schedule the “expose and inspect” review when previous owners left unpermitted work behind. Our General Contractor team doesn’t split time guessing between Inglewood’s city office and Hawthorne’s – we plan for County timelines from the first site visit.
Our phones are answered by a live person 24/7, not a voicemail box, not a bot, not a next-business-day callback. That matters when you’re trying to coordinate a County inspection window that just shifted. Graham Stein and our crew bring background-checked, uniformed technicians to every Westmont job – shoe covers and drop cloths included, never charged extra. We leave a photo of the clean-up before we go. And every project carries our 365-Day Done Right Promise: if it’s not done right after completion, we make it right.
Styles & brands we work with







Licensed General Contractor in Westmont
Licensed General Contractor work in Westmont means navigating LA County’s unincorporated permitting system, where every plan check, revision, and inspection flows through the Department of Public Works instead of any city building department. A typical kitchen remodel in Westmont runs $14,000 – $45,000, a small kitchen update $9,000 – $20,000, and whole-home remodels scale from there depending on how much of the original 1940s – 1960s wood-frame structure we’re opening up. Bathroom remodels generally fall between $9,000 – $28,000, with small baths starting at $5,000 – $12,000.
We see a lot of Westmont homes where the original cripple-wall foundation needs bolting and shear-wall retrofit before we can legally tie new work to the structure. That’s not optional. County inspectors will flag it. We scope for it upfront so the written price you get before any work starts already accounts for the structural prep, not as a surprise after demo.
County Permitting and Inspection Coordination
LA County’s inspection lead times run longer than Inglewood’s or Hawthorne’s city-scheduled pools. We build that buffer into every Westmont timeline. Our crew submits County-specific forms from day one, tracks the plan check queue, and schedules the rough and final inspections with the buffer already built in. No guessing. No “we’ll see when they call us back.”
Exposing and Legalizing Previous Work
Because Westmont has operated without city oversight for generations, unpermitted additions, garage conversions, and electrical upgrades are everywhere. County code requires us to expose and inspect that previous work before new permitted work can proceed. We price for the possibility. If we find it, we handle the County legalization process as part of our scope. If we don’t, you saved money you never spent.
Residential General Contractor in Westmont

Residential General Contractor projects in Westmont sit on a unique landscape of post-WWII tract homes, open lots with well and septic instead of city sewer, and decades of informal construction that County inspectors now scrutinize. A home addition in Westmont typically runs $45,000 – $130,000, a garage conversion $30,000 – $80,000, and a full detached ADU $90,000 – $220,000 – though ADU pricing shifts dramatically once we walk the lot and confirm utility trenching distances, septic setbacks, and whether the crane can access a soft-graded site.
Our General Contractor in Westmont work centers on families with children and pets. We run quiet tools during nap and school hours where the job allows. We ask before moving furniture. We choose pet-safe products where there’s a choice. And we never start work before you have our written price in hand.
Open-Lot Scoping and Access
Westmont properties with acreage, shop buildings, or detached ADU sites demand different quoting than attached additions. We walk the lot to confirm equipment access, haul distances for materials, and whether decades of shifted grading need recontouring before the pad goes in. Skip this step and you’re looking at change orders for drainage work that should have been in the original scope.
Raised-Foundation and Seismic Prep
Those original 1950s wood-frame tract houses on cripple-wall foundations? County seismic codes apply to any substantial remodel. We inspect for existing bolting, evaluate shear-wall needs, and include the retrofit in our written price before you sign. No “we’ll see what the inspector says” pricing.
Trusted Brands We Service in Westmont
We specify named-brand materials our Westmont customers can research independently. Cabinets from KraftMaid and Wellborn. Countertops from Cambria, Silestone, and Caesarstone. Fixtures from Kohler, Moen, and Grohe. Exterior cladding from James Hardie. For detached ADUs and modular additions, we also work with factory-built partners including Abodu, Cover, and Dvele – brands whose manufacturer warranties travel with the finished project, not just our own. We stock common hardware and fixture components locally so a trim piece or matching grout doesn’t stall your County final inspection by two weeks.

AfterCommon General Contractor Problems We See in Westmont Homes
- County permit delays on unpermitted legacy work. We routinely open walls in Westmont homes and find previous owners’ garage conversions or room additions that were never permitted. LA County requires these to be exposed, inspected, and often legalized before our new permitted work can proceed. We scope for this possibility and build contingency into the timeline.
- Asbestos-containing materials in original 1940s – 1960s construction. Original stucco, plaster, and floor tile in Westmont’s housing stock frequently test positive for asbestos. We coordinate certified abatement before structural work continues, and we include abatement testing in our initial site evaluation.
- Drainage failure after El Niño rainfall on shifted grading. The LA Basin’s periodic heavy rain events exploit decades of settled grading on older, densely built Westmont lots. We inspect retaining walls, concrete flatwork, and foundation perimeters for undermining before quoting any addition or ADU pad.
- Utility gaps on open lots with septic and well systems. Properties without city sewer stubs require County well and septic setback clearances that attached-addition contractors rarely encounter. We verify these setbacks before design finalization so the County health permit doesn’t stall your build.

FAQs About General Contractor in Westmont
Westmont is unincorporated, so all permits, inspections, and code enforcement run through LA County rather than a municipal building department. County inspector pools are smaller, lead times are longer, and the forms differ from city-specific packets. We build that extra time into every Westmont timeline and submit County-specific documentation from day one. Call (949) 850-9896 to discuss your project’s permit schedule.
Yes. Open lots with detached structures require us to evaluate equipment access, material haul distances, crane placement on potentially soft or shifted grading, and County well and septic setbacks before we can finalize any price. We walk the lot during your free estimate and itemize these costs in your written quote. Call (949) 850-9896 to schedule that site visit.
We stop new work, document the unpermitted construction, and begin the County’s “expose and inspect” legalization process before proceeding. This is common in Westmont and we price for the possibility upfront. If the condition is worse than expected, we communicate immediately and revise the written scope with your approval. Call (949) 850-9896 to talk through how we handle this contingency.
We include asbestos testing in our initial site evaluation; if positive, we coordinate certified abatement and itemize it separately in your written price. Many Westmont homes built between the late 1940s and 1960s contain asbestos in original stucco, plaster, or floor tile. We find it before demo, not after. Call (949) 850-9896 for a free evaluation of your home’s condition.
We inspect for cripple-wall bolting, shear-wall integrity, and grading drainage as part of every Westmont remodel scope. County inspectors will flag seismic deficiencies on substantial renovations, and El Niño rainfall has undermined many older lots. We include necessary retrofit and re-grading in your written price before work begins. Call (949) 850-9896 to schedule your free foundation and drainage assessment.
