Fast, Reliable Home Renovation Across San Lorenzo
Home renovation in San Lorenzo works differently than in bigger Bay Area cities, and the number one thing homeowners need to plan around is the permit desk, not the labor. Because San Lorenzo incorporated in 2011 and still runs residential plan review and inspections through Alameda County, a kitchen or San Lorenzo Bathroom Remodeling project that takes six weeks in San Leandro can take eight to ten here while drawings move through county review. That’s the reality our crews work around every week, from the 1950s ranches off Via Alamitos to the newer pockets near Hesperian Boulevard.
If you’re pricing a Home Renovation project in San Lorenzo, call us at (254) 272-5876. We give you a written scope and a written price before any tool is picked up, and we schedule around the county inspection calendar from day one so you’re not surprised by a three-week gap mid-project.
Why Sawyer Remodeling Is San Lorenzo’s Preferred Home Renovation Company

We’ve worked on enough San Lorenzo homes to know what hides behind the drywall. The original 1940s and 1950s housing stock in the San Lorenzo Village core was built fast after World War II, and that means undersized headers, slab patches that have heaved, and plumbing rough-ins that don’t meet current Alameda County code. Our San Lorenzo clients get a contractor who’s already seen it and already knows how to fix it, without turning it into a change order fight.
We show up with a live arrival time, photo updates before and after each phase, and a price that was approved in writing before work started. Our background-checked, uniformed technicians are the only people who walk through your door, and you’ll know who’s coming before they arrive. That’s the Relay Visibility Guarantee, and it applies to every project in San Lorenzo whether it’s a $9,000 small bath or a $220,000 ADU.
Call (254) 272-5876 and a live person answers, 24/7. No voicemail loops, no callback queues. Just a direct line to someone who can talk through your project and get an estimate scheduled.
Styles & brands we work with







Whole House Renovation in San Lorenzo
Whole House Renovation in San Lorenzo typically means opening up a 1,100 to 1,600 square foot ranch or split-level and reworking the floor plan without adding square footage. We see it most often on homes around Bockman Road and Grant Avenue where the family has outgrown the original layout but the lot is zoned in a way that makes an addition harder than reworking what’s already there. The work usually runs $45,000 to $130,000 depending on how much structural work the existing framing requires, how far the plumbing and electrical have to move, and what finish level you choose.
Structural Work and Hidden Conditions
San Lorenzo’s 1950s ranches frequently have bearing walls that were framed with undersized headers, and once we open the ceiling we often find wiring and drain lines routed through places current code doesn’t allow. That changes both scope and schedule, which is why we write the permit revision into the plan before demolition starts.
Permit-Led Scheduling
Because plan review runs through Alameda County, whole house work in San Lorenzo needs drawings submitted early and inspections scheduled as the job progresses. We build the county review calendar into your project schedule so a two-week county review doesn’t hit you as a surprise delay after demo.
Home Renovation Contractors in San Lorenzo

Home Renovation Contractors in San Lorenzo have to handle the Alameda County inspection process as carefully as the carpentry. A contractor who doesn’t factor county plan review into the calendar, or who closes a wall before the rough inspection, creates problems that cost the homeowner money and months. We’ve seen the failure mode up close: verbal-only scope agreements, surprise change orders when a homeowner picks a Cambria counter instead of a cheaper option, and load-bearing walls opened without a permit.
What We Put in Writing
Every San Lorenzo project gets a written scope of work and a line-item price before any work starts. That includes your allowances for cabinets, counters, and fixtures at the tier you selected, so a mid-project decision doesn’t become a surprise invoice.
Inspection-Ready Workmanship
We pull permits, schedule county inspections, and walk you through a written punch list before final sign-off. If the inspector flags something, we fix it and reschedule. Nothing closes up until the work behind it is confirmed.
Trusted Brands We Service in San Lorenzo
We stock and install manufacturer-backed materials that hold up in San Lorenzo’s coastal air, which runs damp in winter and swings dry in summer. Countertops from Cambria and Silestone resist the moisture and staining that older laminate can’t. Cabinetry from KraftMaid and fixtures from Kohler give you a warranty that’s backed by a manufacturer, not just our word. We keep fast turnaround on parts for these brands, so if a hinge or a seal fails after the project closes, you’re not waiting weeks for a warranty part to ship.

AfterCommon Home Renovation Problems We See in San Lorenzo Homes
- Undersized headers on load-bearing walls. The 1940s and 1950s framing in San Lorenzo Village was built to a different code, and when we open up a wall between a kitchen and dining room, we often find a header that can’t carry the span. Fixing it properly means a permit revision and an engineered beam, not a box-store patch.
- Heaved slab patches under old cabinets. The original concrete slabs in San Lorenzo’s ranch homes were patched with whatever was handy over the decades. When we pull old cabinets out, we often find the subfloor has moved, and we rebuild it before setting new KraftMaid boxes on top.
- Bathroom rough-ins that don’t meet current code. Moving a toilet or shower drain in an older San Lorenzo home usually means opening the floor and reworking the waste line. Doing that without a third-party inspection confirming what’s behind the wall is how homeowners end up with a closed-up wall and a failed final inspection.
- County plan review lag on small projects. Homeowners budget labor and materials but not the extra weeks that Alameda County plan review adds to the draw schedule. We front-load the permit submission so review happens while other prep work continues, not after the project has already stalled.

FAQs About Home Renovation in San Lorenzo
Plan review through Alameda County typically adds three to six weeks to a San Lorenzo project, depending on scope. Simple interior remodels that don’t move structural walls or plumbing rough-ins often clear faster, while load-bearing wall removal or ADU construction takes the full review window. We submit drawings early and schedule around the county calendar so the review happens in parallel with material ordering and prep work. Call (254) 272-5876 for an estimate on your specific scope.
A kitchen remodel in San Lorenzo runs $14,000 to $45,000 for a full rework, and a small kitchen without structural changes starts around $9,000 to $20,000. The biggest local cost drivers are what’s behind the walls in a 1950s ranch and how far plumbing and electrical have to move. Call (254) 272-5876 for a written, line-item quote.
Yes, if the wall is load-bearing. Opening up a bearing wall without a permit and a properly engineered header is the most common and most expensive mistake we see in San Lorenzo homes. If you’re not sure whether the wall carries the roof load, don’t guess. We’ll confirm it and pull the permit before any work starts. Call (254) 272-5876 and we’ll send someone to look at it.
Yes. ADU construction in San Lorenzo runs $90,000 to $220,000, and a garage conversion runs $30,000 to $80,000. Both require Alameda County plan review and inspections, and the timeline depends on the specific lot and the condition of the existing slab and framing. We handle drawings, permits, and construction as one scope. Call (254) 272-5876 for a free estimate.
The two big ones in San Lorenzo are hidden structural conditions inside 1950s framing and verbal-only scope agreements that don’t spell out finish allowances. We write every allowance into the contract before work starts, and we price the structural unknowns up front so a header revision doesn’t become a surprise change order. Call (254) 272-5876 for a written price before you commit to anything.
