Repairing Livermore houses after water, smoke or mold
Livermore is new ground for us: 3 jobs so far, the first in November 2025 and the most recent in August 2026. Below is what we have learned to watch for in this valley, from its arroyos and its dry summers to a permit office that now works online only.
Short record, honest count
3 jobs in Livermore, November 2025 to August 2026
Three households in Livermore have called us in the last year. Our photo log holds 307 pictures from those visits, shot from the first walk-through to the last day on site. That is a small sample, and this page does not pretend otherwise.
The kinds of work we take on
Water mitigation, mold remediation, fire and smoke cleanup, air duct cleaning, the reconstruction once the damage is handled, and construction and remodeling. Our log counts Livermore visits but does not tag each one by trade, so we will not tell you which of these the three jobs were.
Why you see no job photos here
A job's photos go public only after the homeowner's house is cleared for it, with no faces, house numbers or belongings in frame. None of the Livermore jobs is cleared yet. When one is, its pictures will sit on this page with the month they were taken.
Where storm water goes
A valley drained by arroyos
The City of Livermore's flood history page explains the pattern. Arroyo Mocho, Arroyo Las Positas, Arroyo Seco and Altamont Creek carry winter runoff down from the hills fast. Once they reach the flat valley floor, the city writes, the channels become shallow, and constrictions plus building in some floodplain areas leave the city open to damage in large storms.
The 2022–2023 storms
The city's creeks and floods page notes that it applied for FEMA Public Assistance for places damaged in the 2022/2023 severe winter storm disaster, including spots along the Arroyo Mocho Trail. Those were public trails and banks, but the same rain soaked plenty of private crawl spaces and garages.
Look up your own lot
The city points residents to its GIS map, where turning on the flood zones layer shows whether a property sits in the mapped floodplain. FEMA's Flood Map Service Center holds the official panels behind it.
Outside the line still counts
The same city page says more than a quarter of National Flood Insurance Program claims come from properties outside the 1-percent-annual-chance floodplain, and that a standard homeowner's policy does not cover flooding. A flood policy also has a 30-day wait before it starts.
What we do when it comes in
Water that crossed a yard or a street brings silt with it. We photograph and take readings before anything is moved, pull out what cannot be dried, and keep drying until the numbers say the framing is dry. Everything we record goes into the file for your claim.
Weather and the house
Almost all the rain in five months, then a hot, dry summer
NOAA's 1991–2020 climate normals for the Livermore weather station put the year's rain at 14.6 inches. December, January and February bring 8.23 inches of that; June through August bring less than a fifth of an inch. July's normal daily high is 89 degrees.
November is the month to look up
October's normal is under an inch and November's is about one and a half, before December jumps to nearly three. Gutters, downspouts and roof flashing that sat dry since spring meet their first real test then, and a slow drip into an attic often shows up weeks later as a ceiling stain.
Dry months hide old leaks
From June to September there is next to no rain, so a stain that appears in summer usually points inside the house: a supply line, a toilet seal, a water heater, or an air conditioner's drain line working hard in the heat. We trace the water to its source before we cut anything open.
Mold follows the wet season
Wet framing that never fully dried after a winter storm can grow mold through spring. If it has, everything the mold touched is replaced with new material, never cleaned and reused.
Housing age, from the Census
More Livermore homes date from the 1960s than any other decade
The U.S. Census Bureau's American Community Survey (2020–2024 estimates) counts about 31,900 housing units in Livermore. The 1960s added about 5,800 of them and the 1970s nearly as many, with about 3,700 more from the 1950s (table B25034). The median home was built in 1979, plus or minus two years (table B25035).
About 52 percent built before 1980
Add the decades up and roughly 16,700 Livermore homes, a little over half, were built before 1980. Only about 2,900 went up in 2010 or later. Those older houses have had decades of patches, re-pipes and remodels laid over the original build.
What that means once walls open
In a house of that age, the drywall you see may hide a second layer, an old repair or a pipe that was rerouted. We read moisture through each layer before deciding what comes out, so the tear-out is no bigger than the water made it.
Paint from before 1978
The U.S. EPA's Renovation, Repair and Painting rule applies to work that disturbs paint in homes built before 1978, which takes in most of Livermore's 1950s, 1960s and 1970s houses. Ask anyone who will open your walls how they handle it.
Restoring, then rebuilding
Once the house is dry and clean, we put it back: restoration to rebuild under one call. If you want the kitchen or bath laid out differently while it is open, design is included and the first consultation and quote are free.
Ground under the valley
The 1980 quakes and the faults at the valley's edge
A U.S. Geological Survey report, Surface faulting near Livermore, California, associated with the January 1980 earthquakes, describes a magnitude 5.8 quake on January 24, 1980 and a 5.2 two days later, both north of the city. The ground cracked along the Greenville fault zone for at least 4.2 kilometers, and the Las Positas fault zone moved too.
Check an address
The California Geological Survey's EQ Zapp shows whether a property lies in a mapped fault rupture, liquefaction or earthquake-induced landslide zone. Many homes from 1960s and 1970s tracts were built before any of these maps existed.
The damage we see after shaking
Shaking rarely announces itself as water, but that is often what follows: a flex line pulled off a water heater, a cracked fitting inside a wall. Close the main valve if you can reach it safely, then call us.
City Hall, now online
How Livermore handles permits for a rebuild
The city's online permitting page is blunt: all permits are exclusively online through Accela Citizen Access, nothing is issued over the counter, and there is no rush lane for plan checks.
A Citizen Access account comes first
Every application starts in the portal under Building. Contractors also need a City of Livermore business license that is active for the year before they submit.
Plans go up as files
The intake step lists the plans and documents your type of permit needs. Staff email when something is missing, when corrections are needed and when fees are due.
Inspections are booked separately
The portal does not schedule inspections. The permit and its inspection card arrive by email and must be printed and kept on site for the inspector.
More work needs a permit than people expect
The city's flood guidance says permits are required for any permanent improvement to a structure, painting, roofing, siding, additions and alterations included, and for site work such as grading, even when homeowners do the work themselves.
For remodels and rebuilds we handle the permits and plans, so the portal steps above are ours to carry, not yours.
If it is happening now
Water or smoke in your Livermore house tonight
Safety first
If anyone is in danger, call 911. If floodwater is rising toward outlets or the furnace, the city's flood page tells residents to ask PG&E to shut off power and gas, or for guidance on doing it yourself.
Stop what you can
Close the main water valve for a leak. For smoke, keep doors to unaffected rooms shut so soot does not travel through the house.
Take pictures before moving things
Phone photos of the water line on walls and of damaged items help later. We add our own photos, moisture readings and a line-item estimate in the industry's standard estimating format.

Questions
What Livermore homeowners ask us
Can I get a Livermore rebuild permit at City Hall in person?
No. The City of Livermore says all permits are now exclusively online through its Accela Citizen Access portal, none are issued over the counter, and there is no expedited plan check. Inspections are requested separately. For remodels and rebuilds we handle the permits and plans, so the portal work is ours.
Does Livermore really require a permit for painting or new siding?
The city's flood-recovery guidance says permits are required for any permanent improvement to a structure, including painting, roofing, siding, additions and alterations, and for site work such as grading, even when homeowners do the work themselves. Ask the Permit Center about your exact scope before work starts.
My Livermore house is not in a mapped flood zone. Can it still flood?
Yes. The City of Livermore notes that more than 25 percent of National Flood Insurance Program claims come from properties outside the 1-percent-annual-chance floodplain, and that a standard homeowner's policy does not cover flooding. The city's GIS map has a flood zones layer for checking your lot.
When does Livermore get most of its rain?
NOAA's 1991–2020 normals for the Livermore station show 14.6 inches a year, with 8.23 inches in December, January and February and almost none from June to September. November, with about an inch and a half, is the first real test for roofs and gutters after the dry months.
Is there an active fault near Livermore?
A U.S. Geological Survey report describes surface faulting north of Livermore after the magnitude 5.8 and 5.2 earthquakes of January 1980, along the Greenville fault zone and the Las Positas fault zone. The state's EQ Zapp map shows whether a given address lies in a mapped hazard zone.
