Construction in San Mateo, CA
Kitchen remodeling in San Mateo runs $14,000-$45,000 for a full job, and most of what drives that number has nothing to do with cabinets or counters. The housing stock here was largely built in the 1940s through 1960s, which means undersized electrical panels, outdated framing, and post-and-pier foundations show up the moment a wall comes down. Add the marine layer’s effect on older wood framing, and a San Mateo kitchen job is rarely a straight swap. Call (470) 298-9650 for a written price before anyone picks up a tool.
Why San Mateo Homes Are Different
San Mateo sits in a geologically bifurcated position that directly shapes every construction project. The eastern flatlands near the Bay rest on bay mud and fill with documented liquefaction zones, while the western neighborhoods lie just miles from the San Andreas Fault running through the Crystal Springs Reservoir corridor. Foundation design, soil reports, and seismic retrofit strategies can differ dramatically from one end of the same street to the other. A room addition in a Baywood ranch on post-and-pier construction faces different permit requirements than a similar job east of the Caltrain corridor, where the liquefaction hazard zone can mandate a geotechnical report even for a straightforward addition.
The older neighborhoods tell the story plainly. Homes in Baywood and Beresford, most built before modern seismic codes, frequently need cripple-wall bracing retrofits and foundation bolting before any addition or remodel moves forward. The marine-influenced microclimate compounds the problem: persistent coastal moisture and fog cycling from the Bay side drives higher-than-average rates of dry rot in older wood-framed eaves, siding, and subfloor framing, particularly on north-facing elevations shaded by mature trees. We find this condition on a large share of San Mateo jobs, and we document it in the photo record before we touch anything.
Our Main San Mateo Services
Fence installation and driveway work are the two projects San Mateo homeowners call about most, often because a property sale or a neighbor’s contractor exposed a boundary or drainage problem. Each gets its own dedicated San Mateo page.
Fence Installation in San Mateo
Fence work in San Mateo runs into the same marine moisture problem the houses do: posts set in bay-side soil with poor drainage rot faster than homeowners expect. East of 101, the fill soil holds water against wood posts; west of El Camino Real, the clay slopes shed water unevenly. We specify post depth and base material per property, not per city habit. The flat written price covers demolition, haul-off, post setting, and the finished run, with no change order unless you change the scope. Details on materials and pricing live on the Fence Installation in San Mateo page.

Driveway & Pavers in San Mateo
Driveway work in San Mateo means either replacing cracked concrete on the older flatland lots or installing pavers where drainage needs to move water deliberately. The existing base matters more than the surface: much of the east-side fill settles unevenly, so we check the subgrade before quoting. Pavers from Belgard and Techo-Bloc give us honest material numbers to build a written quote around. The full range of driveway options and San Mateo-specific pricing is on the Driveway & Pavers in San Mateo page.

Before
AfterKitchen Remodeling in San Mateo


A full kitchen remodel in San Mateo typically runs $14,000-$45,000, and the biggest variable is what the original 1950s or 1960s framing reveals once the drywall comes down. Older Baywood and Beresford homes hide undersized electrical panels and dimensional lumber that no longer meets code, so the written quote has to cover what we can see, and the signed change order covers what we find. That is the whole point of our Kitchen Remodeling process: the price is written before work starts, and no change proceeds without your signature.
Full Kitchen Remodeling
Signs you need it
Cabinet boxes pulling away from walls, original galvanized plumbing that has never been replaced, and a layout that cuts the kitchen off from the rest of the house.
What it costs in San Mateo
A full kitchen remodel in San Mateo runs $14,000-$45,000 depending on cabinet line, countertop material, and what the framing inspection uncovers.
How we do it
We open the walls, document the existing framing and electrical with photos, replace what the code requires, then rebuild to the written scope with cabinet and countertop brands named in the quote.
Cabinets & Countertops
Signs you need it
Delaminating cabinet faces, drawer slides that catch, and laminate counters that have swollen at the seams from years of marine moisture.
What it costs in San Mateo
Cabinet installation runs $4,000-$13,000 and countertop installation runs $2,000-$6,500, with KraftMaid, Wellborn, Cambria, and Caesarstone all available as named lines in the written quote.
How we do it
We measure in place, order from the named brand, install the boxes level and the tops with the correct overhang, then document the finished run with photos.
What Kitchen Remodeling Costs in San Mateo
| Item | Typical range in San Mateo |
|---|---|
| Full kitchen remodel | $14,000-$45,000 |
| Small kitchen remodel | $9,000-$20,000 |
| Cabinet installation | $4,000-$13,000 |
What does a small kitchen remodel cost in San Mateo?
A small kitchen remodel in San Mateo runs $9,000-$20,000. The range covers cabinet refacing or replacement, new countertops, and fixture updates without moving plumbing or walls. Call (470) 298-9650 for a written quote on your specific scope.
Will the price change once work starts on a San Mateo kitchen?
No change proceeds without a signed change order. If demolition uncovers wiring or framing that must be brought to code, we document it with photos, write the change order, and wait for your signature before the work continues.
Bathroom Remodeling in San Mateo


A bathroom remodel in San Mateo typically runs $9,000-$28,000, with the lower end covering a cosmetic update and the upper end covering a full gut with framing repairs. In 1940s and 1950s ranches, the original bathrooms are small, the subfloor under the tile is often compromised by dry rot, and the cast iron waste lines have reached the end of their service life. The marine moisture that sits on north-facing walls accelerates the rot in ways we see less often in hotter, drier Peninsula cities. Our Bathroom Remodeling quotes name the specific tile membrane, the vanity line, and the fixture brands before work begins.
Walk-In Showers & Shower Remodeling
Signs you need it
Cracked grout lines that let water behind the tile, a shower pan that flexes underfoot, or a curb that has rotted at the corners.
What it costs in San Mateo
Walk-in shower installation in San Mateo runs $4,500-$12,000, and shower replacement runs $3,000-$8,500 depending on the waterproofing method and tile selection.
How we do it
We tear out to the studs, inspect the subfloor for dry rot, install a waterproof membrane, rebuild the pan with the correct slope, and document the membrane before tile goes on.
Tub-to-Shower Conversion
Signs you need it
A tub that no longer works for a household member with mobility limits, or a tub surround that has failed at the seams and damaged the wall behind it.
What it costs in San Mateo
Tub-to-shower conversion in San Mateo runs $3,500-$10,000, including demolition, waterproofing, drain relocation if needed, and the finished tile or surround.
How we do it
We remove the tub, check the subfloor and framing, set the new drain at the correct location, waterproof the entire wet area, and install the finished surface per the written scope.
What Bathroom Remodeling Costs in San Mateo
| Item | Typical range in San Mateo |
|---|---|
| Bathroom remodel | $9,000-$28,000 |
| Small bathroom remodel | $5,000-$12,000 |
| Walk-in shower installation | $4,500-$12,000 |
How long does a San Mateo bathroom remodel take?
Most San Mateo bathroom remodels run two to four weeks from demo to final fixture. The schedule depends on what the framing inspection finds under the old tile. Call (470) 298-9650 for a written timeline with your quote.
Do you pull permits for bathroom remodels in San Mateo?
Yes. Any job that moves plumbing, changes the drain location, or opens wet walls gets permitted. The permit history stays with the photo record and the written scope, so the next buyer sees the documentation.
Roofing in San Mateo


A roof replacement in San Mateo runs $8,000-$20,000, and the marine layer is the invisible variable behind that range. Coastal moisture that cycles in from the Bay keeps north-facing eaves damp for longer stretches, which accelerates dry rot in older wood-framed homes and means a roof job here often includes soffit and fascia repair the homeowner never saw from the ground. Older ranch homes in Baywood and Beresford also carry multiple shingle layers from decades of re-roofs over the original 1950s decking. Our Roofing quotes name the shingle brand and layer count in writing before the tear-off starts.
Roof Repair
Signs you need it
Water staining on the ceiling below north-facing eaves, granule loss in the gutters, or a shingle tab that lifted after a winter storm.
What it costs in San Mateo
Roof repair in San Mateo runs $400-$1,800 for most isolated damage, with tile roof repair at $600-$2,500 for cracked or displaced clay tiles.
How we do it
We identify the leak source from the attic side when possible, replace the damaged shingles or tiles, check the flashing at penetrations, and photograph the repair before we leave.
Roof Replacement & Installation
Signs you need it
Multiple shingle layers from prior re-roofs, decking that has softened at the eaves, or a roof that has passed its expected service life under coastal moisture.
What it costs in San Mateo
A full roof replacement in San Mateo runs $8,000-$20,000 depending on the shingle brand, layer count, and whether the decking or soffit framing needs replacement.
How we do it
We tear off to the decking, document what we find with photos, replace damaged sheathing per the written scope, install the underlayment and shingles, and write any change order before it proceeds.
What Roofing Costs in San Mateo
| Item | Typical range in San Mateo |
|---|---|
| Roof replacement | $8,000-$20,000 |
| Roof repair | $400-$1,800 |
| Metal roof installation | $15,000-$40,000 |
How many shingle layers can a San Mateo roof carry?
California building code allows a maximum of two shingle layers. Many San Mateo homes from the 1950s already carry two, which means the next job is a full tear-off to the decking. We document the layer count in the written quote.
Does the marine layer affect roof installation timing in San Mateo?
Yes, mostly in spring and early summer. Coastal fog keeps dew on the decking later into the morning, which affects adhesive curing and underlayment installation. We schedule around the moisture window rather than force the work.
Windows & Doors in San Mateo


Window replacement in San Mateo runs $4,500-$15,000 for a typical 1950s or 1960s ranch home, and the driving factor is usually the original single-pane aluminum frames carrying decades of marine moisture damage at the sills. North-facing elevations in tree-shaded neighborhoods like Baywood show the worst dry rot in the surrounding framing, which means a window job is rarely just a window swap. The existing rough opening often needs reframing before the new unit goes in. Our Windows & Doors quotes list the exact window line, the frame material, and the flashing method in writing before the first unit is ordered.
Window Replacement
Signs you need it
Condensation between panes, sills that have softened at the corners, or aluminum frames that feel cold against the interior wall in winter.
What it costs in San Mateo
Window replacement in San Mateo runs $4,500-$15,000 for a typical full-home job, with impact window installation at $8,000-$25,000 for larger or specialty units.
How we do it
We measure the existing openings, check the surrounding framing for dry rot, order the units to the written spec, and install with flashing details that handle the coastal moisture load.
Door Installation
Signs you need it
A front door that sticks in the winter, reveals daylight at the weatherstripping, or has a threshold that has rotted where the marine fog collects.
What it costs in San Mateo
Door installation in San Mateo is quoted as part of the full window and door scope, typically $4,500-$15,000 for a whole-home project including entry and rear doors.
How we do it
We remove the old door and frame, inspect the rough opening for rot, install the new pre-hung unit level and square, and flash the threshold correctly against the damp side of the house.
What Windows & Doors Costs in San Mateo
| Item | Typical range in San Mateo |
|---|---|
| Window replacement | $4,500-$15,000 |
| Impact window installation | $8,000-$25,000 |
| Full window and door replacement | $4,500-$15,000 |
Are impact windows worth it in San Mateo?
San Mateo does not face hurricane-force wind, so impact windows are a choice about noise reduction and glass safety near mature trees rather than code compliance. The $8,000-$25,000 range reflects thicker laminated glass and heavier frames.
How long does window replacement take in San Mateo?
Most San Mateo window replacements finish in three to five working days for a single-story ranch, longer if reframing is required at multiple openings. The written quote includes the schedule. Call (470) 298-9650 for a detailed timeline.
Home Additions & ADU in San Mateo

A home addition in San Mateo runs $45,000-$130,000, and an ADU runs $90,000-$220,000, but the number that matters most on this side of the Peninsula is the soil report. East of 101, the liquefaction hazard zone often mandates a geotechnical report even for a straightforward room addition, which adds a line item many Peninsula contractors do not anticipate when quoting jobs near the Caltrain corridor. The same job in the western hills above El Camino Real faces a different foundation conversation entirely. Our Home Additions & ADU quotes account for the geotech step in writing, before the first inspection is scheduled.
ADU Design & Permitting
Signs you need it
A lot large enough for a detached unit, a family member who needs proximity without shared walls, or a garage that has stopped functioning as a garage.
What it costs in San Mateo
ADU construction in San Mateo runs $90,000-$220,000, with the design and permitting phase included in the written scope but priced as a distinct line item.
How we do it
We run the soil report when the lot requires it, submit the permit package with the geotech included, and build per the stamped plans with change orders for anything the city revises.
Garage Conversion ADU
Signs you need it
An attached or detached garage that no longer holds a car, with a slab that is in usable condition and a roofline that can accept insulation and finishes.
What it costs in San Mateo
Garage conversion in San Mateo runs $30,000-$80,000 depending on whether the existing slab passes inspection or needs to be cut and re-poured.
How we do it
We verify the slab elevation and drainage, frame the interior within the existing shell, run new electrical and plumbing where the floor allows, and convert the garage door opening per the permitted plan.
What Home Additions & ADU Costs in San Mateo
| Item | Typical range in San Mateo |
|---|---|
| Home addition | $45,000-$130,000 |
| ADU construction | $90,000-$220,000 |
| Garage conversion | $30,000-$80,000 |
Does a San Mateo ADU require a geotechnical report?
East of 101, in the liquefaction hazard zone, yes, often even for a garage conversion. The geotech report is a standard line item in our San Mateo ADU quotes, not a surprise change order later.
How long does a San Mateo ADU take from permit to finish?
Typically eight to fourteen months depending on city plan check timing and soil conditions. The written quote separates design, permitting, and construction so the schedule is visible from the first page. Call (470) 298-9650 to review your lot.

What pushes the price up in San Mateo is the soil and the original construction: east-side fill and liquefaction zones add geotech and foundation costs, while 1950s framing and dry rot from the marine layer add repair scope the moment a wall opens.
