Water damage restoration in Hillside, Daly City
The Hillside corridor runs through the middle of Daly City, and so does a good cross-section of its housing history. Along Hillside Boulevard, up toward the Top of the Hill, the homes are older and mixed — no single tract, no single era — which means the water problems here are as varied as the streets themselves.
One house has original galvanized plumbing quietly rusting in the walls. The next has a tired roof that gives up during the first real storm. A third sits low enough on the corridor to catch runoff sliding down from the surrounding slopes near School Street. What they share is age, and age is what turns a small drip into a soaked wall while you are not looking, then hides it long enough for the framing to stay wet for days.
We restore water damage all along the Hillside corridor, from the blocks near School Street and Marchbank Park up to the Top of the Hill in the 94014 ZIP. Call (201) 277-9344 and we will dispatch a crew right away with thermal cameras, air movers, and moisture meters, ready to find the source, stop the spread, and dry it out.

What makes Hillside homes vulnerable
Local housing, terrain, and climate shape the water damage we see here.
The central Hillside corridor
Hillside Boulevard is one of Daly City's original spines, and the residential blocks around it grew up over decades rather than all at once. You will find modest older single-family homes, in-law units, and small multi-unit buildings side by side, each with its own plumbing vintage and its own quirks — which is why we never assume the cause before we meter the walls.
Mixed older residential stock
Because the housing here spans several eras, there is no single culprit for water damage. Some homes still carry galvanized steel and cast iron end to end; others have seen partial updates that leave old and new plumbing joined together, and the transition fittings where copper or PEX meets aging galvanized become weak points that corrode and weep on their own schedule.
Top of the Hill proximity
The corridor climbs toward the Top of the Hill, one of the city's higher and windier points. Homes up here catch wind-driven rain and sit above streets that shed runoff downhill, so both roof leaks and ground-level water intrusion show up along this stretch — sometimes in the same house during the same storm.
Common causes of water damage in Hillside
Aging and mismatched plumbing
With housing of many ages, the corridor sees the full range of pipe failures — corroded galvanized supply lines, cracked cast-iron drains, and leaks at the joints where old plumbing meets newer repairs. We trace the water to its actual source with meters and thermal imaging rather than chasing the stain, because on a mixed system the leak is often nowhere near where it shows.
Roof and ceiling leaks
Older roofs along Hillside Boulevard give way under sustained rain and wind, letting water into attics and ceilings. It shows up as brown rings and sagging drywall, sometimes rooms away from where the roof actually failed, because water tracks along the framing until it finds a seam to drip through. We dry the cavity and repair the ceiling once it reads dry.
Storm runoff at lower blocks
Homes on the downhill side of the corridor collect water running off the higher streets during heavy rain. Blocked drains and worn weatherproofing let that runoff reach garages and ground floors at the slab edge. We extract and dry quickly to prevent secondary damage to plates, subfloor, and the base of the walls.
Appliance and water heater failures
In these older homes, aging water heaters and worn appliance hoses are frequent offenders. A tank that fails at a rusted seam or a hose that splits can flood a laundry area or hallway overnight, soaking flooring and the base of the surrounding walls before morning. We dry both sides of every affected wall so nothing stays damp behind the finish.
Hillside homes and water damage
Hillside Boulevard runs along the lower western slope of San Bruno Mountain, and the blocks around it were built over a long stretch of time rather than as one tract. Older single-family houses sit next to duplexes, fourplexes, and small apartment buildings. Many single-family homes now have a rented unit downstairs. That mix affects how water damage plays out. A small building may have one water heater and one main shutoff for several households, and the person who knows where the valve is may not live there. In owner-occupied homes with a downstairs rental, the tenant is usually the first to see a leak, and the owner upstairs often caused it. On the uphill side of the boulevard, the backs of lots face the mountain's slopes, which send runoff toward rear walls in winter.
When water damage tends to happen in Hillside
Runoff off the mountain slopes
Rain that falls on the grassy and brushy slopes of San Bruno Mountain doesn't soak in for long once the ground is wet. Homes on the uphill side of the corridor get that water at their back fences and rear walls, often carrying sand and silt. A rear patio drain that clogs can let water reach a downstairs unit's back door in a single storm.
Full houses over the holidays
Many homes along the corridor are multigenerational, and the holidays add more people. More showers, more laundry, and more cooking load old drain lines that were sized for smaller households. A partial clog that went unnoticed all year can back up into a downstairs shower or laundry sink during a holiday week, often at night.
Vacant units and turnovers
When a unit sits empty between tenants, nobody is there to notice a running toilet, a dripping supply valve, or a slow leak under the kitchen sink. That can happen any time of year, but turnovers are common in summer. A drip that runs for weeks in an empty unit can soak the subfloor and the ceiling of the unit below.
Protecting a Hillside home from water damage
- In a building with more than one unit, label the main shutoff and each unit's valves, and make sure every household knows where they are.
- Clear rear patio and yard drains on the uphill side of the lot before the rainy season, since that is where runoff from the slopes arrives.
- If you have a downstairs tenant, give them your phone number and the plumber's, and ask them to report damp spots or drips right away.
- Check a vacant unit every few days: flush the toilets, look under the sinks, and turn off the supply valves to fixtures nobody is using.
- Have the main drain line cleaned before the holidays if your house has had slow drains or gurgling during the year.
Water utility for Hillside
City of Daly City Department of Water and Wastewater Resources
Along the Hillside Boulevard corridor, most homes and small apartment buildings are billed by the City of Daly City. Call (650) 991-8200, available 24 hours, for water rising from the street or meter box. The City asks residents not to shut the meter off themselves. Tenants should tell the owner or manager right away, since the building's shutoff and plumbing are the owner's responsibility. If your bill comes from Cal Water, call the number on it.

You can be. Partial updates often leave old galvanized and new copper or PEX joined together, and those transition fittings are common leak spots as the older metal keeps corroding around them. Along the Hillside corridor we see a lot of these mixed systems, so we check the joints and the remaining old runs, not just the newest sections.
Often, on these older homes, yes — but water travels along framing before it drips, so the stain can be some distance from the actual leak. We use a thermal camera and moisture meter to find the true entry point, dry the space above the ceiling to standard, and repair the drywall properly so the ring does not bleed back through the paint.
Yes. We take the job from emergency extraction and drying through the rebuild — drywall, ceilings, flooring, and paint — so you deal with one crew from start to finish and the finished repair matches what the drying confirmed was dry underneath.
Around the clock. A real person answers the phone 24/7, and we roll a crew to the Hillside corridor whenever you call, because water damage does not wait for business hours and neither does the mold clock once materials get wet.
Move your electronics and valuables away from the water, then tell the owner or property manager right away so they can shut off the water upstairs. Photograph the ceiling, the wet floor, and anything damaged. If you can't reach anyone and the water keeps coming, call us. The owner's insurance generally covers the building, and renters insurance generally covers your belongings, so keep your own photos. Our [apartment water damage service](/services/apartment-water-damage/) coordinates with landlords and tenants.
Water crossing private yards is usually the property owner's to manage, through grading, patio drains, and channels that carry it to the street. If a City storm drain or street gutter is overflowing onto your lot, report it through the City's non-emergency lines on its [Storm Preparedness page](https://www.dalycity.org/1136/Storm-Preparedness). We can dry what gets inside and show you where the water entered. A drainage contractor can then design the fix.
