San Leandro damage repair and rebuilds

On our books

Three San Leandro jobs, from December 2024 to October 2026

Three jobs is a small number, and we would rather show it plainly than dress it up. Our first San Leandro job opened in December 2024 and the latest in October 2026.

Across those three houses our crews took 824 photos. They live in each homeowner's job file and go to the insurer when there is a claim. None of those owners has cleared photos for the web yet, so this page shows our mascot instead of their homes.

Our job log does not record which kind of work each visit was, so we will not tell you these were water jobs or remodels. What we can tell you is the full list of what we do: water mitigation, mold remediation, fire and smoke cleanup, air duct cleaning, the rebuild once the damage is handled, and construction and remodeling. All of it comes from one company and one phone number.

The housing stock

Built in the postwar boom: what that means when something breaks

San Leandro is a 1950s city on paper. The Census Bureau's latest five-year survey puts the median San Leandro home in 1959, and more homes went up in that one decade than in any other.

The American Community Survey for 2020–2024 counts 31,954 housing units in the city. Of those, 8,415 were built from 1950 to 1959, another 4,824 in the 1940s and 3,547 in 1939 or earlier (year structure built, table B25034; median year built, table B25035, margin of error one year). Count every decade up to 1979 and about 77 % of the city's homes were built before 1980. Only about 6 % were built in 2000 or later.

Generations of plumbing repairs

A house that has stood since the 1950s has usually had its plumbing patched by more than one owner, old pipe joined to new. When one of those joints lets go, the water usually finds the subfloor before anyone finds the leak. We trace it with a moisture meter, room by room, and dry to the numbers.

Raised floors and crawl spaces

If your house sits over a crawl space, water that drops below the floor can stay there for weeks. Crawl space drying is part of our water work, and mold found under the house is handled as mold remediation: whatever it grew on is removed and replaced with new material.

Paint older than the rules

Federal lead-safe rules apply to renovation in homes built before 1978, under the EPA's Renovation, Repair and Painting program. By the census numbers, that is most of San Leandro. It is a fair thing to ask anyone who plans to open your walls.

A rule that surprises people

Why a permitted rebuild can mean new toilets and faucets

The City of San Leandro applies a state law, SB 407, that asks for old, water-hungry plumbing fixtures to be swapped for water-conserving ones when a house gets additions, alterations or improvements under a permit. It applies only to properties built on or before January 1, 1994.

The city spells this out on its permits and plan check page: the swap has to happen before the permit is finaled. With nearly nine in ten San Leandro homes built before 1990, most owners who pull a permit to rebuild a bathroom or kitchen after a leak will meet this rule. We would rather you hear about it at the start than at the final inspection, so it goes into the scope we walk through with you, along with any upgrades you choose, which are priced separately.

Permits and codes

What City Hall expects once the walls go back up

Getting a house dry rarely starts with a permit. Putting framing, wiring, plumbing and finishes back often does, and in San Leandro that work is checked against a code book that changed this year.

New code editions since January 1, 2026
The city's building codes sit in its Municipal Code, Title 7, Chapter 7-5, and the current set took effect on January 1, 2026, built on the 2025 California codes. The city notes that structural provisions were modified for earthquake design.
Where the torn-out material goes
Wet drywall, ruined flooring and old cabinets add up fast. Since January 1, 2023, permitted residential projects must recycle or salvage at least 65 % of their nonhazardous construction and demolition waste, with receipts shown to the inspector before the permit is finaled.
Who handles the paperwork
On remodels we handle the permits and the plans, and design is included. The first consultation and quote are free, for restoration and for remodeling.

All three points come from the same city permits page. For a question about your own house, the Permit Center staff at City Hall are the ones who decide what needs a permit.

Flood maps

When flood rules decide how a damaged house is rebuilt

San Leandro takes part in FEMA's National Flood Insurance Program, and parts of the city are mapped as special flood hazard areas. The flood insurance rate map in force today was issued on December 21, 2018.

That comes from the city's National Flood Insurance Program page, which also says new construction, additions and remodels in those zones must follow rules meant to limit flood damage. To see the zone for one address, type it into FEMA's Flood Map Service Center.

The 50 % line

The city's page on construction in flood zones defines substantial damage: when bringing a house back to its before-damage condition would cost 50 % or more of its market value or replacement cost. The city says damage of any origin counts, not only flooding.

What crossing it means

A building that is substantially damaged or substantially improved has to be brought up to the city's flood damage prevention rules, including raising it to or above the base flood elevation. That can reshape a rebuild, so it is worth asking early.

Our part

Our line-item estimate for the repair is written in the industry's standard estimating format, so the cost of putting the house back is laid out item by item. We document the damage with photos, moisture readings and measurements from the first visit.

Rain

Do the hills above San Leandro get more rain than the flats?

By NOAA's numbers, yes. The weather station at the Upper San Leandro filter plant, in the hills at the city's eastern edge, averages 25.25 inches a year, against 18.68 inches at Oakland's airport down by the bay.

Both figures are NOAA's 1991–2020 climate normals (Upper San Leandro Filters station; Oakland airport station). At the hill station, December is the wettest month at 5.12 inches, about 82 % of the year falls from November through March, and a normal July brings none.

For a homeowner that means two things. A roof or gutter problem can sit quietly through a dry summer and show up with the first heavy storm. And on a hillside lot, runoff from above adds to what falls on your own roof. If a storm has opened the house, we tarp or board it up and dry what got wet; the details are on storm damage repair and water damage mitigation.

Under the house

Look up your lot's earthquake hazard zones

The East Bay sits on active faults, and the state maps where the ground itself is a concern. The California Geological Survey's EQ Zapp shows whether an address is in a fault rupture, liquefaction or earthquake-induced landslide zone.

It takes a minute and it matters when a rebuild grows into structural work. A quake that cracks plaster also breaks pipes, so the first call after shaking is often a water call, followed by the rebuild after damage.

How a job runs

From the first call to the last coat of paint

Someone answers
We are open 24/7 and a person picks up, not a menu. Tell us which rooms are affected and whether the water is still running.
We stop the damage and record it
Water out, wet materials opened up, drying set. Photos, moisture readings and measurements go into your file from day one.
The insurer gets what it needs
We send our itemized estimate to your adjuster and answer questions about our scope; the claim itself stays between you and your insurer. For a covered repair you pay only your deductible, and your insurer pays us the rest directly. More on working with insurance.
Then we build it back
The same company rebuilds, with a written warranty whose terms are in your contract. Plenty of calls are not damage at all: kitchens, baths and additions are on construction and remodeling, with financing through our lending partner.

The first consultation and quote are free.

Asked in San Leandro

San Leandro homeowners' questions, answered

My San Leandro house is in a flood zone. Could a big repair mean raising the house?

It can. The city says that when restoring a house would cost 50 % or more of its market value, damage of any origin, the building must meet its flood rules, including raising it to or above the base flood elevation. Ask the city's Building and Safety division early.

Will a San Leandro bathroom rebuild mean replacing the old toilet and faucets?

Often, yes. Under SB 407, the city requires non-compliant plumbing fixtures to be replaced with water-conserving ones before a permit for additions, alterations or improvements is finaled, for properties built on or before January 1, 1994. We put it in the scope from the start.

What happens to the wet drywall and flooring torn out of a San Leandro house?

On a permitted project in San Leandro, at least 65 % of the nonhazardous construction and demolition waste has to be recycled or salvaged, under the 2025 California Green Building Standards Code. Recycling receipts are shown to the city inspector before the permit is finaled.

Does a house in the San Leandro hills see more storm leaks than one near the bay?

It gets more rain. NOAA's 1991–2020 normals give 25.25 inches a year at the Upper San Leandro filter station in the hills and 18.68 at Oakland's airport by the bay. More rain plus runoff from uphill lots puts more water on roofs, gutters and drainage.
