Why Elmstead Remodeling San Francisco Is Martinez’s Preferred General Contractor Company
Martinez homeowners keep our phone number because of how we handle what’s behind the walls. Older Craftsman and Spanish Revival homes in Martinez often hide knob-and-tube wiring, undersized framing, and foundation movement from expansive clay soil. We inspect before we quote, write allowances into the contract for what we might find, and price any surprise in writing before touching it.
Our crew arrives with shoe covers at the door and drop cloths on the floors, every job, included in the price. We use quiet tools during children’s sleep hours where possible and choose pet-safe products when there’s a choice. Parents and pet owners don’t have to ask us to be careful; the Cedarwell Care Promise makes it the default.
Graham Stein leads our team, and he takes the same approach on a $9,000 small bathroom remodel as he does on a $130,000 home addition. Written price first. Photo of the clean-up before the crew leaves. And if something isn’t done right after the job is complete, the 365-Day Done Right Promise means we make it right.
Styles & brands we work with
General Contractor Services in Martinez
General Contractor Services in Martinez cover the full scope of residential remodeling: kitchen renovations, bathroom remodels, whole-home updates, room additions, and basement finishing. A kitchen remodel in Martinez typically runs $14,000 – $45,000, while a full bathroom remodel falls between $9,000 and $28,000. Home additions, which often trigger the city’s most careful geological review, range from $45,000 to $130,000.
Kitchen and Bath Remodels
Most Martinez kitchens we open up are in homes built before 1960. That means original framing, outdated wiring, and sometimes failed waterproofing where decades of winter rain found a way in. We plan for those discoveries before demolition starts.
Bathroom remodels in Martinez follow the same discipline. A small bathroom remodel runs $5,000 – $12,000, and a tub-to-shower conversion runs $3,500 – $10,000. We use named-brand fixtures from Kohler, Moen, and Grohe, and cabinets from KraftMaid and Wellborn, so the warranties on the products are real and verifiable.
Hillside Additions and Structural Work
Home additions on sloped Martinez lots are a different animal from flat-land additions in neighboring cities. The city’s geological review can take months, and deep caissons or retaining walls are common requirements. We bring geotechnical input in early, before plans are finalized, so the permit process doesn’t stall the schedule.

Construction Company in Martinez
As a Construction Company serving Martinez, we handle the structural, foundation, and framing work that most design-build firms won’t touch. When a load-bearing wall comes out, the house doesn’t care who designed the kitchen; it cares whether the beam was sized correctly and the load path was preserved. We do that work with permits pulled and inspections passed.
Foundation and Drainage
Martinez’s hot, dry summers and cool, wet winters make the expansive clay soils swell and shrink. That movement causes cracks in foundations, stuck doors, and cracked tile after the first rainy season. Any remodel that touches a foundation or adds weight to a hillside home needs a drainage and soil-stabilization plan, not just a patch.
Opening Walls and Code Upgrades
Once walls are open, the city requires certain upgrades: outdated electrical brought to current code, smoke detectors tied to the panel, sometimes shear wall additions for seismic safety. We write these into the contract as allowances so the cost doesn’t arrive as a surprise after demo day.
Trusted Brands We Service in Martinez
We stock and install materials Martinez homeowners can research by name. Cabinets from KraftMaid and Wellborn. Countertops from Cambria. Exteriors from James Hardie. We keep our Martinez crews supplied with the same product lines so lead times stay short and replacements, if ever needed under warranty, are straightforward. The manufacturer’s warranty travels with the finished project, and our 365-Day Done Right Promise covers our workmanship on top of it.

AfterCommon General Contractor Problems We See in Martinez Homes
- Knob-and-tube wiring behind original plaster. Pre-1960 Martinez homes often still have original electrical systems. Opening a wall means the city will require rewiring before insulation and drywall go back. We budget for it in the allowance so you’re not hit mid-project.
- Expansive clay soil movement. The shrink-swell cycle in Martinez clay causes foundation cracks and door frames that no longer square. Remodel plans that don’t account for soil stabilization end up with cracked tile within a year.
- Hillside ordinance surprises. Any slope disturbance along roads like Alhambra Valley Road needs geological review. Deep caissons and retaining walls can add tens of thousands to a home addition. We start that review early, not after plans are submitted.
- Failed waterproofing at the foundation line. Winter rain in Martinez finds failed flashing and rotted subfloors. When we open a wall for a remodel, we regularly find rot that never showed on the surface. We stop, photograph it, price it in writing, and get your signature before rebuilding.

Call (831) 480-4497 for a free estimate on your specific project.

FAQs About General Contractor in Martinez
Hillside permits in Martinez can take months due to geological review, often 3 to 6 months depending on the slope and the scope. The way to keep your remodel on schedule is to bring a geotechnical engineer in before plans are finalized, which is what we do on every sloped lot. Call (831) 480-4497 and we’ll walk you through the timeline for your specific property.
Yes, if your home was built before 1960, there’s a strong chance we’ll find original knob-and-tube wiring. The city will require it to be replaced once walls are open, and we handle that with a written change order, a clear scope, and your signature before any new wiring goes in.
The hillside ordinance requires geological review for any slope disturbance, and depending on the lot, deep caissons and retaining walls may be mandated. We plan foundation and drainage work around those requirements from day one, so the permit process doesn’t stall the project.
We include soil stabilization and drainage allowances in the original contract, so when the clay soil movement shows up in a foundation inspection, the budget already accounts for it. If the scope grows, you get a written change order before we proceed, never after.
For a hillside remodel in Martinez, you can expect geological review, structural engineering review, and city building inspections at multiple stages: foundation, framing, electrical, plumbing, and final. We schedule and attend every inspection, and we pull all permits in our name.
If you’re planning a remodel in Martinez and want a contractor who knows the hillside ordinance, the older housing stock, and the clay soil before the first crew member walks in, call (831) 480-4497 for a free estimate. We’ll give you a written price, walk you through what we expect to find behind your walls, and treat your home like the place where your family actually lives.
