Why Elmstead Remodeling Is San Lorenzo’s Preferred General Contractor Company
We’ve built our reputation in San Lorenzo on one thing: showing up the way we’d want someone to show up at our own home. That means shoe covers and drop cloths on every visit, a written price before any work starts, and a photo of the clean-up before the crew leaves. Our 365-Day Done Right Promise covers every completed project – if it’s not done right, we make it right. That’s the longest-standing post-project commitment in our service area.
Calls are answered by a live person 24/7, not a voicemail box or automated system. When you call (949) 850-9896, you’ll speak to someone who can schedule your free estimate and answer questions about your specific project. Our technicians are background-checked and uniformed, so families know exactly who is walking through the door.
We know San Lorenzo’s housing stock intimately. The Bohannon-era tract homes built from 1944 to 1954 dominate this community, and their cripple wall foundations, shallow mudsills, and aging subfloor framing create predictable patterns we’ve encountered across nearly every block. This local knowledge means fewer surprises and more accurate quotes.
Our General Contractor team serves San Lorenzo with the Cedarwell Care Promise: Clean up like it is our own home; Ask before we move or touch anything; Respect the family’s time and quiet hours; Explain the price before the work.
Styles & brands we work with
Licensed General Contractor in San Lorenzo
Licensed General Contractor work in San Lorenzo covers everything from structural retrofits of aging Bohannon foundations to full kitchen and bathroom remodels, room additions, and ADU construction. A typical San Lorenzo kitchen remodel runs $14,000 – $45,000, while bathroom projects range from $9,000 – $28,000. Home additions start around $45,000 and can reach $130,000 depending on scope, with ADU construction running $90,000 – $220,000 and garage conversions falling between $30,000 – $80,000.
When San Lorenzo homeowners need a licensed general contractor, it’s often because they’re facing one of three situations: their 1940s – 1950s foundation needs seismic retrofitting to meet modern codes, they’re expanding living space on a tight lot where every square foot matters, or they’re updating systems that have reached end of life. The Hayward Fault proximity makes the first category especially urgent here.
Seismic Retrofit and Foundation Work
The Bohannon homes’ unbolted mudsills and cripple wall construction predate modern seismic codes by decades. We anchor-bolt sills, add plywood shear panels, and replace rotten subfloor framing while keeping load-bearing walls intact. Every retrofit starts with a structural assessment and a written price.
Additions and ADUs on Tight Lots
San Lorenzo’s narrow lots and shared wall situations mean parking plans and party-wall notices often drive the schedule more than the framing. We handle the neighbor coordination and permit complexity that density creates.
Residential General Contractor in San Lorenzo
Residential General Contractor services in San Lorenzo focus on the specific challenges of living in a Bohannon tract home while raising a family. Kitchen remodels at $14,000 – $45,000 and bathroom updates at $9,000 – $28,000 represent the bulk of our San Lorenzo work, but whole-home remodels and room additions are common as families outgrow the original 1,000-square-foot layouts.
San Lorenzo’s East Bay flatland position near San Lorenzo Creek creates persistent ground moisture and fog-driven dampness that accelerates wood rot in older subfloor framing and exterior stucco. The creek’s flood plain also means some parcels carry drainage and grading constraints that affect additions, ADUs, and foundation work. We account for these conditions in every quote.
Family-Focused Project Management
We schedule noisy work outside children’s sleep hours where possible, use pet-safe product choices where available, and ask before moving furniture or touching personal items. Shoe covers and drop cloths are standard on every job, not charged as add-ons.
Material Partners Homeowners Can Verify
Our cabinet, surface, fixture, and building-material partners include KraftMaid, Wellborn, Cambria, Silestone, Kohler, Moen, Grohe, Schluter, and James Hardie. These are brands you can research independently, and their warranties travel with your finished project.
Trusted Brands We Service in San Lorenzo
We stock and install named-brand materials that carry manufacturer warranties homeowners can verify independently. For San Lorenzo’s moisture-prone environment, we often specify James Hardie fiber-cement siding and Schluter waterproofing systems in wet-area remodels. Our cabinet partners KraftMaid and Wellborn, countertop suppliers Cambria and Silestone, and fixture lines from Kohler, Moen, and Grohe mean you choose from products with real warranty backing, not generic alternatives. For foundation and structural work, we specify Sakrete mixes calibrated for Bay Area soil conditions. Fast turnaround on parts matters on tight San Lorenzo lots where staging space is limited and schedule delays cascade quickly.

AfterCommon General Contractor Problems We See in San Lorenzo Homes
- Unbolted mudsills and cripple wall failure risk. Nearly every Bohannon home in San Lorenzo was built with shallow mudsills that were never anchor-bolted to the foundation. We see this condition repeated house after house across the community, and it’s the primary driver of our seismic retrofit queue.
- Moisture-damaged subfloor framing near San Lorenzo Creek. The flatland position and persistent fog-driven dampness accelerate rot in the original 2×8 joist bays, especially in rear additions and kitchen bump-outs where grade drainage is poorest.
- Outdated electrical and plumbing at end of life. Knob-and-tube remnants, galvanized supply lines, and subpanel configurations that can’t handle modern loads are standard in these 70-year-old systems. We open walls with the expectation of finding multiple generations of DIY patches.
- Tight-lot access blowing the draw schedule. Long hose carries from the street, no staging area, and parking restrictions under San Lorenzo’s posted work-hour limits quietly add labor hours that inexperienced contractors don’t price in.

FAQs About General Contractor in San Lorenzo
Access constraints add labor hours that we price in upfront, not as change orders later. On narrow San Lorenzo lots, we account for long material carries from street parking, hose and power runs, and the fact that we can’t stage a full delivery at once. The quote includes these real conditions.
Yes, for most additions, ADUs, and seismic retrofits in San Lorenzo’s Hayward Fault zone. We maintain relationships with local engineers who know the Bohannon foundation types, which speeds the process and keeps permit submissions clean. Call (949) 850-9896 and we’ll coordinate the engineering as part of your project scope.
Assuming every Bohannon house is identical and accepting a quote without a subfloor inspection. We’ve opened floors to find nonstandard mudsills, previous owner modifications, and moisture damage that changes the scope. We inspect before we quote, so the price you get is the price you pay.
Shoe covers and drop cloths on every visit, quiet tools during family rest hours where possible, and written party-wall notice before shared-wall work begins. We stage materials in the driveway, park on the street under posted work-hour limits, and take a photo of the clean-up before the crew leaves. On Via Del Sol we retrofitted a 1948 Bohannon ranch: the existing mudsill was shallow and unbolted, so we anchor-bolted the sill, added plywood shear panels to the cripple walls, and replaced rotten subfloor framing near the rear addition while keeping the load-bearing wall intact. We staged materials in the driveway, parked the crew on the street under San Lorenzo’s posted work-hour limits, and gave the neighbor sharing our wall written notice before the first hammer swung – inspection sign-off came without a single complaint.
Yes, we pull all required permits and coordinate inspections as part of our standard project management. San Lorenzo’s unincorporated Alameda County status means permits route through the county rather than a city office, which we navigate regularly. Call (949) 850-9896 to schedule your free estimate – we’ll outline the permit path for your specific project.
