AfterRemodeling Company in Corte Madera, CA
Home remodeling in Corte Madera runs $9,000 – $130,000 depending on scope, with most whole-home projects falling between $45,000 and $130,000 once foundation stabilization and flood-zone compliance are factored in. We’re Penhallow Remodeling, and we handle kitchen remodels, bathroom remodels, and whole-home renovations for Corte Madera homeowners from the flatlands near Corte Madera Creek to the hillside streets above Highway 101. Our crews are dispatched from the San Francisco Bay Area office, so we’re local to the job site, not driving down from Sacramento or across from the East Bay. Call (936) 259-2607 and we’ll schedule a free estimate with a written price before any work starts.
Why Corte Madera Homes Are Different
Corte Madera’s flatland neighborhoods sit on former tidal marsh fill, and that changes everything about how we approach a remodel here. Much of the area along Corte Madera Creek and the bay edge falls within FEMA flood Zone AE, which means finished floor elevations must sit 1 – 2 feet above Base Flood Elevation under local amendments. We’ve seen projects where a standard grade-level entry or garage slab had to be redesigned mid-permit because the initial drawings didn’t account for this overlay. Neighboring Larkspur or Mill Valley simply don’t trigger this requirement at the same frequency.
The housing stock reinforces the challenge. The flatlands hold post-WWII tract homes built from the 1950s through the early 1970s on shallow post-and-pier or slab foundations placed directly over compressible bay mud. Decades of differential settlement have left many homes with out-of-level floors, cracked slabs, and crawl spaces that have partially subsided. Foundation work becomes a near-constant component of any serious remodel or addition. On the hillside lots, steeper grades and mid-century custom builds introduce their own constraints, but it’s the flatland flood-zone compliance that catches most homeowners off guard.
Climate layers on more complexity. The town’s position between the bay and the Marin hills funnels persistent coastal fog and moisture into low-lying parcels, accelerating wood rot, fastener corrosion, and mold in crawl spaces. King tides periodically inundate properties near the creek even without storm events, so waterproofing detailing, sump systems, and elevated mechanical equipment aren’t upgrades here. They’re practical necessities written into our standard scope for flat-area builds.
Our Main Corte Madera Services
Most Corte Madera homeowners who call us start with one of these three projects, though we also handle full whole-home renovations when the scope expands.
General Contractor in Corte Madera
As general contractors in Corte Madera, we coordinate the full trade stack for projects that need structural, mechanical, and finish work sequenced correctly. On flatland homes, that means scheduling geotechnical reports and engineered foundation solutions before framing can begin. We pull permits through the Town of Corte Madera, handle flood-zone compliance documentation, and keep the job site clean and secure from demo through final walkthrough. Every project gets a written price upfront and our 365-Day Done Right Promise in writing. General Contractor in Corte Madera
Bathroom Remodeling in Corte Madera
Bathroom remodels in Corte Madera range from $5,000 for a small bathroom refresh to $28,000 for a full gut renovation with walk-in shower and relocated fixtures. On flatland homes, we often find moisture damage in subfloors and wall cavities from crawl-space humidity, so our demo phase includes thorough substrate inspection before we set new tile or install cabinetry. We specify moisture-resistant cement board substrate (the layer behind your tile that stops water from reaching framing) and Kohler or Moen fixtures that carry their own warranties alongside ours.

Kitchen Remodeling in Corte Madera
Kitchen remodels in Corte Madera typically run $14,000 – $45,000, with small kitchens starting at $9,000. We see a lot of original 1960s and 1970s kitchens with failing layouts, inadequate electrical for modern appliances, and cabinets that have absorbed decades of fog-cycle humidity. Our process starts with a written line-item quote covering cabinetry from KraftMaid or Wellborn, countertops in Cambria, Silestone, or Caesarstone, and fixture packages from Kohler, Moen, or Blanco. We don’t start demolition until you’ve approved every number in writing. Kitchen Remodeling in Corte Madera

Home Remodeling in Corte Madera
Whole-home remodeling in Corte Madera addresses the specific conditions that make these houses difficult to update piecemeal: compromised foundations on bay-mud fill, flood-zone elevation requirements that affect entries and garages, and moisture systems that have to be integrated across the entire envelope rather than room by room. We approach Home Remodeling as a single coordinated project because trying to sequence a kitchen remodel before addressing the crawl space or foundation typically means tearing out that new kitchen two years later. Our written price covers the full scope, including any geotechnical or structural engineering required for flatland compliance.
Whole House Remodel
Signs you need it
Your floors slope noticeably, doors no longer latch, multiple rooms need updating simultaneously, or you’ve been told your home needs flood-zone elevation work that affects the whole structure.
What it costs in Corte Madera
Whole-house remodels in Corte Madera typically run $45,000 – $130,000, with the upper range reflecting foundation stabilization, engineered fill, or elevated first-floor reconstruction on flood-zone parcels.
How we do it
We start with a structural and geotechnical assessment, then sequence foundation repair, moisture mitigation, mechanical rough-in, and finish work with a single project manager coordinating permits and inspections through the Town.
Home Renovation
Signs you need it
Your home functions but feels dated, systems work independently but don’t integrate well, or you’re preparing to age in place and need accessibility modifications throughout.
What it costs in Corte Madera
Home renovations in Corte Madera generally fall between $9,000 for focused room updates and $55,000 for more extensive reconfigurations that don’t require structural foundation work.
How we do it

|---|---|
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Garage Conversion | $30,000 – $80,000 |
Do I need a geotechnical report for a home remodel in Corte Madera?
Yes, if your home sits on the flatlands near Corte Madera Creek or the bay edge, most permit applications now require a geotechnical report documenting soil stability and liquefaction risk before foundation work can proceed. The Town’s flood-zone overlay also means finished floor elevations must be verified against Base Flood Elevation, which the engineer calculates. Call (936) 259-2607 and we’ll review your parcel’s requirements during our free estimate.
Can we live in the house during a whole-home remodel?
Sometimes, but Corte Madera’s moisture issues often require extensive crawl-space work that disrupts HVAC, plumbing, and electrical simultaneously, making full occupancy impractical during the structural phase. We phase projects to minimize displacement and always give you a clear timeline in writing before work starts. Call (936) 259-2607 to discuss your specific situation.

FAQs About Remodeling Company in Corte Madera
Standard remodel permits through the Town of Corte Madera typically take 4 – 6 weeks for review, but flood-zone parcels require additional FEMA documentation and elevation certificates that can add 2 – 4 weeks. We handle all permit applications as part of our project management and flag potential delays during the estimate phase.
Yes, several Corte Madera neighborhoods and condo associations require architectural review before exterior work begins. We submit the same detailed scope and material specifications we use for permits, and we don’t start work until both Town and HOA approvals are in hand.
We stop work, document the condition with photos, and present a revised scope and price in writing before proceeding. Our upfront price covers the work we can see and reasonably anticipate; hidden conditions like subsided piers or saturated subgrade trigger a change order only after you’ve approved the additional scope. The 365-Day Done Right Promise still covers all completed work regardless of how the scope evolved.
