Fast, Reliable General Contractor Across Santa Monica
Hiring a general contractor in Santa Monica means more than finding someone who can swing a hammer. It means finding a company that understands the Coastal Zone, the seismic retrofit rules, and what salt air does to building materials over a decade. Penhallow Remodeling Los Angeles runs crews throughout Santa Monica every week, from Sunset Park to Ocean Park, and we coordinate scheduling from our Los Angeles office. When you call (213) 277-6578, a live person answers. Not a voicemail. Not a callback window. We’ll talk through your project, give you a written price before any work starts, and stand behind the job with our 365-Day Done Right Promise.
Why Penhallow Remodeling Los Angeles Is Santa Monica’s Preferred General Contractor Company

Santa Monica homeowners have dealt with enough contractors who hand out verbal estimates that evaporate the moment demolition starts. That is not how we operate. Trevor Nash leads our General Contractor team under the Kingswell standard: a written price before the first tool comes off the truck, a real arrival window, and a written guarantee on every project. The number on day one is the number on the invoice.
Our technicians are background-checked and arrive in uniform, so you know who is walking into your home. We carry materials from recognized trade brands like James Hardie, Cambria, and Kohler, which means the products behind our guarantee are as solid as the promise itself. When a Santa Monica homeowner calls us about a kitchen remodel on a 1930s Spanish Revival in Ocean Park or a bathroom update in a 1950s bungalow in Sunset Park, we already know what the building department will ask for. That local familiarity saves time and prevents expensive surprises.
Styles & brands we work with







Residential General Contractor in Santa Monica
Residential general contractor work in Santa Monica covers the full scope of a home project: pulling permits, coordinating trade crews, managing the schedule, and making sure every inspection passes. A Santa Monica homeowner typically brings us in when the job involves multiple trades, structural work, or Coastal Zone permit requirements. Rather than juggling four separate companies, you get one point of contact and one written price. Kitchen remodels in Santa Monica typically run $14,000 to $45,000 depending on layout, cabinet line, and countertop material. Bathroom remodels fall between $9,000 and $28,000.
Coastal Zone Permitting
Properties inside Santa Monica’s Coastal Zone boundary often trigger discretionary review for work that would be over-the-counter in Culver City or other inland cities. If your home sits within the zone in Ocean Park or Sunset Park, even a kitchen remodel can require a coastal development permit. We scope that into the written price and the schedule before rough-in, so you are not hit with a change order mid-project.
Seismic Retrofit Scope
Many pre-1980 Santa Monica homes fall under the city’s mandatory seismic retrofit ordinance. Soft-story apartments and older wood-frame structures frequently need shear wall upgrades or foundation work when you open up walls for a remodel. We coordinate with structural engineers and the building department to fold those requirements into the project without derailing the timeline.
Hire a General Contractor in Santa Monica

When you hire a general contractor in Santa Monica, ask for the warranty in writing before you sign anything. Our 365-Day Done Right Promise covers every project: if the work fails inside the guarantee period, we come back and fix it at no charge. That includes a free second visit if a repair fails, with no service call and no re-inspection fee. We also provide a written price before any work starts, always, so you can hold us to the number.
Home additions in Santa Monica run $45,000 to $130,000 depending on foundation work, square footage, and whether the property is in a hillside zone or coastal overlay. Window replacement falls between $4,500 and $15,000, and the coastal-spec version costs more for good reason, which we explain below. Roof replacement ranges $8,000 to $20,000. Vinyl fence installation sits between $3,500 and $9,000.
Written Price Before Work Starts
We do not give estimate ranges or verbal ballparks. You receive a written line-item price that spells out materials, labor, permits, and disposal. If the job changes because you change your mind, we write a change order and you approve it before we proceed. No surprises on the final invoice.
Clean Job Site, Real Arrival Window
The Kingswell Way has been our operating standard since 2004. We show up in the window we gave you, we keep the job site clean at the end of every day, and we leave your home cleaner than we found it. For families living through a remodel, that matters as much as the tile work.
Trusted Brands We Service in Santa Monica
We install and work with products from Cambria, Silestone, James Hardie, Kohler, and Wellborn, among others. We also see plenty of projects in Santa Monica where prefab or panelized manufacturers like Abodu or Cover come into play for ADU construction, and we coordinate those installations as the onsite general contractor. Because we run crews in Santa Monica regularly, we can pull materials quickly and keep your schedule moving. If a product has a manufacturer warranty, like Cambria quartz, we make sure you get the paperwork so that warranty sits alongside our own 365-Day Done Right Promise.

AfterCommon General Contractor Problems We See in Santa Monica Homes
- Interior-grade fasteners on exterior components. Standard galvanized hardware rusts within two years in the salt-air zone. We specify stainless or hot-dip galvanized fasteners on decks, railings, and any coastal-facing hardware, and we flag existing rust streaks during estimates so homeowners understand why the previous job failed.
- Underestimated Coastal Zone permit path. A homeowner starts a remodel, the city requires a discretionary review, and the project stalls for months. We scope the permit path before we write the price, so the schedule you approve is the schedule we hold.
- Inland-grade paver joints near the beach. Standard joint sand and sealers erode under salt and fog, leaving pavers shifting within a season. In beach-proximate Santa Monica neighborhoods, we use sealed joints and marine-grade paver products, and we price that difference into the original quote.
- Rotted sill plates from corroded window frames. We see this constantly in 1950s bungalows in Sunset Park, where original galvanized frames have been eaten by the marine layer. The fix is not a simple window swap. It often means cutting out rotted framing and installing marine-grade aluminum frames with stainless fasteners.
Pricing for General Contractor in Santa Monica, CA
Santa Monica pricing runs higher than nearby inland cities like Burbank or North Hollywood, and the reason is the local material spec and the permit path. Coastal-spec windows with marine-grade aluminum frames cost more than the inland-spec version, but the inland-spec version corrodes and fails within a decade. Here is what you can expect for common projects in Santa Monica:
| Project | Santa Monica Price Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Window Replacement | $4,500 – $15,000 |
| Roof Replacement | $8,000 – $20,000 |

FAQs About General Contractor in Santa Monica
We specify stainless steel or hot-dip galvanized fasteners and connectors for every exterior deck, railing, and coastal-facing component. Standard electro-galvanized hardware will show rust streaks within two years in Santa Monica’s salt-air zone. Stainless costs more up front but lasts the life of the structure. Call (213) 277-6578 for a written quote on your deck or railing project, and we will itemize the hardware spec so you can compare it against any other bid.
If your home was built before 1980 and falls under Santa Monica’s seismic retrofit ordinance, the city may require shear wall upgrades, foundation bolting, or soft-story remediation when you pull permits for a remodel. That means work you did not plan for, and it should be scoped before you start. We identify retrofit triggers during our initial walkthrough and include them in the written price, so the kitchen remodel does not stall at rough-in. Call (213) 277-6578 and we will help you figure out whether your property is affected.
Coastal-spec window replacement in Santa Monica typically costs 15 to 25 percent more than the inland-spec version of the same job, because marine-grade aluminum frames and stainless hardware cost more than standard vinyl or interior-grade components. Window replacement overall runs $4,500 to $15,000. The gap is real, but the inland-spec window will corrode and fail within a decade; the coastal-spec window will not. Call (213) 277-6578 for a free estimate and we will show you both options with real numbers.
No. If your property is inside Santa Monica’s Coastal Zone, you cannot legally start major remodel work until the coastal development permit is approved. Starting early risks a stop-work order and fines. Some homeowners try to begin with non-structural work, but the city’s enforcement has gotten stricter. We plan the permit path into the schedule from day one so there is no illegal work, no stop order, and no surprise delay. Call (213) 277-6578 and we will check whether your property is inside the Coastal Zone boundary before you commit to anything.
The morning marine layer introduces moisture that slows paint and stucco curing times, particularly on west-facing walls in Ocean Park and Sunset Park. We schedule exterior finishes around the fog pattern, often pushing critical curing windows to midday and afternoon, and we use moisture meters to confirm the substrate is ready before primer goes on. Rushing this step leads to peeling and cracking within a year. Call (213) 277-6578 to schedule a free estimate, and we will talk through the right finishing schedule for your specific street.
