Winter storm season comes first in Aliso Viejo
The City of Aliso Viejo's homepage currently warns that a strong El Nino winter is expected in 2026 to 2027, with a risk of flooding. When a city says that in autumn, it is a cue to work on the house now. Clear gutters and downspouts, look at roof flashing, and check the seals around windows and patio doors before the first heavy rain.
Rain rarely stays where it enters. It follows framing, runs along a rafter and shows up as a stain in a different room, so crews trace it with thermal imaging and a moisture meter. Fresh rain is Category 1 at first, but it picks up dirt in insulation and loses that status the longer it sits.
Wood Canyon Wilderness Park, with its year-round streams, sits beside the developed neighborhoods. If your home backs onto open space, watch the grade and the drains near the foundation in wet weather.
When water is spreading in Aliso Viejo
Call (949) 670-0939 now, because dispatch is staffed 24/7 and licensed, insured crews can go out with same-day response when available. In a condo or townhome the clock runs faster, since water crosses a floor or a shared wall into someone else's home.
Knock on the neighbors below or beside you if you can do so safely, and tell dispatch which units may be wet.
Water through the ceiling?
Someone below may be getting wet too. Call before the stain spreads to another unit.

Why most Aliso Viejo leaks involve more than one household
The city's housing element reports that more than 60 percent of homes are multifamily or attached, and over two-thirds of all housing was built after 1990. SR-73 divides the community, which was planned as a 20,000-unit community. For a leak, that means shared walls, stacked bathrooms and common roofs are the normal setting.
The Aliso Viejo Community Association, described by the city as the first community-wide property owners' association of its kind in California, maintains most slopes, medians and parks. A hillside seep or a clogged slope drain outside your wall is worth a call to the association before you hire anyone.

Who to tell first in an attached building
| Situation | Tell first | What the crew does |
|---|---|---|
| Water coming from the unit above | Association or manager, then the neighbor | Dries your side, records moisture readings by room |
| Leak inside a wall from a shared line | Association or manager | Finds the wet cavity with thermal imaging, opens as little as needed |
| Roof or balcony leak in storm weather | Association | Extracts, dries and documents the ceiling below |
| Your own water heater or supply line | You and your insurer | Full mitigation, then repair scope |
| Slope seep outside the wall | Aliso Viejo Community Association | Protects the interior and notes the outside source |
Responsibility depends on your governing documents and policy. Read both, and ask the association who handles which pipes.
Before we arrive: a short list for apartments and townhomes
Close the nearest valve
Try the angle stop at the fixture, then the unit's shutoff. If neither works, the building main may need the manager.
Skip wet outlets
If the panel is dry you may switch off breakers for the wet area. Wet floor around the panel means call 911 or the utility.
Protect what is portable
Move electronics, documents and bedding up and away from the wet wall.
Avoid sewage water
If a drain overflowed, keep everyone out of the room and do not use the toilet.
Photograph and notify
Take timestamped photos, send the manager a message, then call dispatch.
Water districts and permits
Aliso Viejo is served by two districts. Moulton Niguel Water District lists the city, and El Toro Water District serves portions of it. The city does not say which streets use which, so read your bill for the district name.
The city contracts for building and safety, and City Hall is at 12 Journey, Suite 100, phone 949-425-2500. The city homepage links to permits and inspections. How much needs a permit depends on the work, so ask the city before any wall or floor is rebuilt.
Drying work in attached buildings is commonly guided by ANSI/IICRC S500, the published standard for professional water damage restoration. It gives a shared vocabulary for water categories and drying goals, which helps when an association manager or a neighbor's insurer asks what was done.
Services in the order attached homes usually need them
Most calls here start with water mitigation, because the first job is to stop water traveling between units. Air movers, LGR dehumidifiers and moisture mapping run in every affected room. Afterward comes water damage cleanup for wet insulation, damaged baseboards and cleaning, and water damage repair once readings are dry.
If a pipe has burst and water is standing, emergency water removal pulls it out first. Crews also serve Laguna Niguel and Lake Forest.
Insurance when two policies are involved
In an attached home, both your policy and the association's may come into play. Policies typically draw lines by cause and by what part of the building is yours, so ask the adjuster and the manager which policy responds. Keep a log of calls and receipts, and let the adjuster look before anything permanent is rebuilt.
Aliso Viejo water damage questions
Dispatch covers 92656, the city's street-delivery ZIP code, which includes City Hall at 12 Journey. If your mail uses another ZIP but your home is inside Aliso Viejo, call and give your street address.
Yes. The line at (949) 670-0939 is open 24/7, with same-day response when available. Call 911 first if wiring is wet or anyone is hurt.
Call dispatch to start drying, then notify your association manager and your insurer. Responsibility depends on the cause, your governing documents and the policies involved, so photograph everything.
Either Moulton Niguel Water District or El Toro Water District. The city does not publish a street split, so your water bill is the quickest answer.
It depends on scope. The city contracts for building and safety and lists permits and inspections on its homepage, with City Hall at 949-425-2500. Ask before opening walls or replacing fixtures.
Clear gutters and downspouts, look for gaps around roof penetrations, and check that patio and yard drains run freely. Photograph the condition now so a later claim has a baseline, and report roof concerns to your association.
Growth can start within 24 to 48 hours in materials that stay wet, which is why drying begins at once. Without moisture it has nothing to feed on, so the leak is repaired first. See a physician for health concerns.
