AfterConstruction in San Leandro, CA
Kitchen remodeling in San Leandro typically falls between $14,000 and $45,000 for a full job, and the number moves depending on what hides inside a 1950s ranch home’s walls. Most of the work we quote here starts with the same discovery: post-war wood framing, original cripple-wall foundations, and moisture patterns from the bay’s marine air that have been quietly working on the structure for 60 years. Call (470) 298-9650 for a written price before any work starts.
Why San Leandro Homes Are Different
San Leandro sits directly on the Hayward Fault, which the USGS lists as one of the highest-probability sources of a major Bay Area earthquake. That single fact shapes more construction decisions here than any design trend. The city’s housing stock is dominated by wood-frame ranch homes and California bungalows built between the 1940s and 1970s, many still on their original cripple-wall foundations with no seismic bracing to speak of. We see it on nearly every remodel: open up a wall in a home near Estudillo Estates or Bancroft and the studs are fine, but the connection to the foundation was never strapped. West of I-880 near the Marina and Davis Street corridor, the soil adds another layer. Those flatlands sit on Bay mud and fill that carries real liquefaction risk in a strong quake, so any serious foundation or addition work there usually requires a geotechnical report before the first permit gets pulled. The marine microclimate does its own thing too, with persistent moisture hammering older wood windows, exterior trim, and roof sheathing in ways you don’t see in drier inland cities.
Our Main San Leandro Services
Fence and driveway work are the two calls San Leandro homeowners make most often before a bigger remodel starts, usually because the outside of the property needs to hold up before the inside gets torn apart.
Fence Installation in San Leandro
Wood fences in San Leandro fight two enemies at once: the bay’s moisture from the west and the steady wind that works loose post anchors in older concrete. Redwood and cedar both hold up, but the post bases need proper drainage and the hardware has to be rated for the marine air or it rusts out in five years. We write the post depth, material grade, and hardware spec into the quote before any digging begins. Fence Installation in San Leandro runs $3,500 to $9,000 for vinyl and $4,000 to $10,000 for aluminum, with wood typically inside those bands depending on height and lineal feet.
Driveway & Pavers in San Leandro
Concrete and paver driveways on the bay side of San Leandro need base preparation that accounts for what’s underneath: fill soil that settles unevenly and doesn’t drain the way native soil does. Cracking and sinking are the predictable result when a crew pours over an under-compacted base. Our quotes specify the base depth, compaction spec, and drainage fall so the number on paper matches the work that actually happens. Driveway & Pavers in San Leandro ranges from $7,000 to $18,000 for pavers and $4,500 to $12,000 for concrete depending on square footage.

BeforeAfterKitchen Remodeling in San Leandro
A full kitchen remodel in San Leandro usually lands between $14,000 and $45,000, and the wide spread comes down to what’s behind the drywall and under the floor. Most of the homes we open up are 1940s-to-1970s ranches and bungalows, which means original plumbing runs, unbraced cripple walls at the foundation line, and floor framing that’s shifted enough to throw a new cabinet line out of level. The moisture in the air near the bay also means older subfloors around sinks and dishwashers have often started to soften. Anyone planning a kitchen here should expect the quote to account for some structural correction before finish work begins. That’s what our written scope does: it names the condition as found, not as hoped. We’ve written about the full process on our Kitchen Remodeling page, and every quote includes a documented photo record of what the crew found on day one.
Full Kitchen Remodeling
Signs you need it
Floors slope or bounce, cabinets pull away from walls, and the layout hasn’t worked since the house was built.
What it costs in San Leandro
A full kitchen remodel in San Leandro typically runs $14,000 to $45,000 depending on layout changes, cabinet grade, and what structural correction the floor framing needs.
How we do it
We open the walls, document what’s actually there, correct any framing or plumbing issues, then rebuild to the written scope with signed change orders before any deviation.
Cabinets & Countertops
Signs you need it
Drawers stick, box frames have swollen from sink moisture, and countertops show seams pulling apart or laminate peeling at the edges.
What it costs in San Leandro
Cabinet installation runs $4,000 to $13,000 and countertop installation $2,000 to $6,500 in San Leandro, with brand choice like KraftMaid or Cambria moving the number.
How we do it
We measure to the existing wall condition, specify the cabinet and countertop brands by name in the written quote, and install to a documented order that shows each piece before and after.
Backsplash, Tile & Flooring
Signs you need it
Grout cracks and falls out, tile has lifted from water intrusion, and the original sheet flooring has worn through to the subfloor.
What it costs in San Leandro
Backsplash installation in San Leandro runs $800 to $2,500, with tile and flooring work quoted by square foot against the condition of the subfloor we find.
How we do it
We check the substrate for moisture and level before setting tile, specify the membrane and setting materials by brand, and document the layers with photos at each stage.
Kitchen Island Installation
Signs you need it
The kitchen has floor space but no work surface where you need it, and the electrical service doesn’t yet feed an island location.
What it costs in San Leandro
A kitchen island installation in San Leandro typically runs $3,000 to $10,000 depending on cabinetry, countertop material, and whether new circuits need to be pulled through the slab or floor framing.
How we do it
We locate the electrical and any plumbing runs before cutting, build the island to the written cabinet and top specs, and pull the permits when new circuits are required.

Only if you sign a change order. The written scope covers what we find during demo, and if something changes, the new price is written down and signed before the work proceeds. Estimates are free.
Bathroom Remodeling in San Leandro
A bathroom remodel in San Leandro runs $9,000 to $28,000 for a full job, and the condition of the subfloor drives more of that number than most people expect. These post-war homes were built fast, and 60 years of bay-adjacent humidity means the original framing around tubs and toilets has often had rot working on it for decades. The fix is straightforward: open it up, document it, replace what’s failed, and rebuild to a written scope. Our Bathroom Remodeling page covers the process, and every San Leandro bathroom quote includes the photo record from demo day.

A full bathroom remodel in San Leandro typically runs $9,000 to $28,000 depending on layout changes, fixture grade, and the extent of subfloor replacement.
How we do it
We remove finishes to the framing, replace any rotted subfloor or studs, install a proper waterproof membrane, and set fixtures to the written list.

How we do it
We tear out to the studs, check the drain and subfloor, install the waterproofing membrane and the shower base to the written spec, and document each layer.
Tub-to-Shower Conversion
Signs you need it
The tub is hard to enter, the original cast iron is stained, and the homeowner wants a curbless or low-threshold entry.
What it costs in San Leandro
A tub-to-shower conversion in San Leandro runs $3,500 to $10,000 depending on drain relocation and the condition of the floor framing below.
How we do it
We remove the tub, assess the drain location against the written plan, reinforce the floor if needed, and rebuild to the specified shower configuration.
Vanities, Tile & Fixtures
Signs you need it
The vanity has water damage at the base, tile is dated or failing, and fixtures show mineral buildup or leaks at the supply lines.

Will the price change once the bathroom is opened up?
Only with a signed change order. The written quote covers the conditions we expect; if demo reveals something different, the new price is written down and you sign before work continues.
Roofing in San Leandro
Roof replacement in San Leandro runs $8,000 to $20,000, and the biggest cost drivers are the number of existing shingle layers and what’s happened to the plywood sheathing underneath. The bay’s marine air means older roofs here fail from moisture as often as from age, especially along north-facing slopes that never fully dry. We find rotted fascia and softened sheathing on a lot of 1950s ranches near Washington Manor and Floresta Gardens. The written quote specifies the shingle brand, underlayment, and the per-sheet cost for any sheathing that needs replacing, so the number doesn’t change on paper later. See Roofing for how the full process works.
Roof Repair
Signs you need it
Shingles are missing or curling, there’s staining on the ceiling below, or a leak appears after the winter rain pattern settles in.
What it costs in San Leandro
Roof repair in San Leandro runs $400 to $1,800 depending on the size of the affected area and whether the decking underneath has also failed.
How we do it
We find the actual leak path, document the damaged area with photos, replace the failed material, and give you a written condition report on the rest of the roof.
Roof Replacement & Installation
Signs you need it
The roof has multiple repaired patches, the shingle granule layer is worn through in large areas, or the decking shows soft spots from the attic side.
What it costs in San Leandro
A roof replacement in San Leandro runs $8,000 to $20,000 depending on square footage, tear-off layers, and the brand of shingle specified in the written quote.
How we do it
We tear off to the decking, replace any failed sheathing at the written per-sheet rate, install the specified underlayment and brand of shingle or tile, and photograph the completed installation.
Metal Roofing
Signs you need it
The existing roof has failed twice in a decade, and the homeowner wants a material that will outlast the structure’s next remodel.
What it costs in San Leandro
Metal roof installation in San Leandro runs $15,000 to $40,000 depending on panel profile, roof complexity, and whether the existing roof must be torn off first.
How we do it
We install the metal system to the manufacturer’s written spec, with the substrate condition documented and any required replacement included in the quote.
What Roofing Costs in San Leandro
| Item | Typical range in San Leandro |
|---|---|
| Roof replacement | $8,000 - $20,000 |
| Roof repair | $400 - $1,800 |
| Metal roof installation | $15,000 - $40,000 |
| Tile roof repair | $600 - $2,500 |
Does roof work in San Leandro trigger seismic requirements?
Roofing itself doesn’t, but we often find unbraced cripple walls while accessing the roof structure from the attic. If the scope expands, the written change order covers it before any work proceeds.
How long does a roof replacement take in San Leandro?
Most roof replacements run two to five days depending on tear-off layers, decking condition, and weather windows. The written schedule is part of the estimate. Call (470) 298-9650.
Windows & Doors in San Leandro
Window replacement in San Leandro runs $4,500 to $15,000 depending on the count, size, and whether the original wood frames have rotted from decades of bay moisture. The marine air here is relentless on west-facing openings, and we replace more sills and exterior trim in San Leandro than in drier cities. A door with a failing threshold lets moisture into the subfloor every time it rains, and the damage hides until the floor starts to soften. Our Windows & Doors page explains the full approach, and every San Leandro quote names the specific window and door brands we’re pricing, not a vague “contractor grade” line.
Window Installation
Signs you need it
Windows are drafty, condensation builds between panes, or the original wood frames show soft spots when probed.
What it costs in San Leandro
Window installation in San Leandro is quoted by the opening, with most whole-home jobs landing from $4,500 to $15,000 depending on window count and frame condition.
How we do it
We remove the old window, assess the framing for rot, replace what’s failed at the written rate, and install the specified brand with proper flashing and sealing.
Door Installation
Signs you need it
The door sticks, the threshold has rotted, or the existing door no longer seals against the marine air.
What it costs in San Leandro
Door installation in San Leandro is priced per opening, with exterior doors running inside the $4,500 to $15,000 band when grouped with a window package.
How we do it
We pull the old door, inspect the sill and subfloor for moisture damage, replace any failed material, and install the specified door with the hardware named in the quote.
Impact Windows & Doors
Signs you need it
The home sits west of I-880 near the bay, or the homeowner wants the highest wind and impact rating available for the location.
What it costs in San Leandro
Impact window installation in San Leandro runs $8,000 to $25,000 depending on the opening count, frame material, and the specific impact rating specified.
How we do it
We specify the impact product by brand and rating, install to the manufacturer’s written requirements, and provide the documentation showing the installation meets the spec.
What Windows & Doors Costs in San Leandro
| Item | Typical range in San Leandro |
|---|---|
| Window replacement | $4,500 - $15,000 |
| Impact window installation | $8,000 - $25,000 |
| Door installation | $800 - $3,000 per opening |
Does window replacement require a permit in San Leandro?
Most like-for-like window replacements don’t, but any change to opening size or structural headers does. We pull what’s needed and the written quote says so up front. Call (470) 298-9650.
Will the price change once the old windows are removed?
Only with a signed change order. The quote includes the per-opening rate for rotted framing, so you know the worst-case number before work starts.
Home Additions & ADU in San Leandro
A home addition in San Leandro runs $45,000 to $130,000, and an ADU $90,000 to $220,000, but the ground underneath changes those numbers faster than the square footage does. West of I-880 near the Marina and Davis Street corridor, the Bay mud and fill soils carry liquefaction risk that a geotechnical report must address before foundations are designed. In the central and hillside neighborhoods, the older homes need cripple-wall bracing and foundation evaluation before any addition ties in. Some San Leandro projects need both. The written quote handles it by naming the geotech and structural work as line items from the first estimate. See Home Additions & ADU for the full process.
ADU Design & Permitting
Signs you need it
The homeowner wants to add a rentable unit on the property and doesn’t have drawings or a clear permit path.
What it costs in San Leandro
ADU construction in San Leandro runs $90,000 to $220,000 depending on size, site conditions, and the foundation design required by the geotechnical report.
How we do it
We bring the design and structural scope together, pull the permits, document the site conditions, and build to the written specification with each permit inspection passed.
Garage Conversion ADU
Signs you need it
The existing garage is a stand-alone structure that could become living space but has never been conditioned or insulated.
What it costs in San Leandro
A garage conversion in San Leandro runs $30,000 to $80,000 depending on the framing condition, foundation type, and how much new plumbing and electrical are required.
How we do it
We document the existing condition, bring the structure to the written code requirement, and convert the space to living area with the same change-order discipline as a new build.
New Detached ADU
Signs you need it
The backyard has space for a separated unit and the homeowner wants a structure that doesn’t touch the main house’s roofline or foundation.
What it costs in San Leandro
A new detached ADU in San Leandro runs $90,000 to $220,000 depending on size, foundation type required by the soil report, and finish level.
How we do it
We site the unit, build the foundation to the geotechnical report’s specification, and run all trades to the written flat price with no work proceeding without a signed change order.
What Home Additions & ADU Costs in San Leandro
| Item | Typical range in San Leandro |
|---|---|
| Home addition | $45,000 - $130,000 |
| ADU construction | $90,000 - $220,000 |
| Garage conversion | $30,000 - $80,000 |
Does an ADU in San Leandro require a geotechnical report?
Often yes, especially west of I-880 where Bay mud and fill soils carry liquefaction risk. The report feeds the foundation design, and the written quote includes that work as a line item.
Will the price change once the foundation is excavated?
Only with a signed change order. The written scope covers the expected condition; if the soil report or excavation reveals something different, the new number is written before work continues.
Brands We Service in San Leandro
We work with over fifty vetted material brands, so the written quote names what’s actually going into the job. Mighty Buildings and Dvele are two panelized and prefab manufacturers we specify for ADU and addition work in San Leandro when the site allows it. Our brands page shows the full list.
