Burst supply line, overflowing toilet, a storm that found the weak spot in your roof: whatever let the water in, the clock started when it did. One call to +1-323-329-3586 routes you to an independent restoration pro in San Mateo County who takes emergency calls around the clock.


We are a free referral line. Business Leak Detection does not send out its own crews; every call is matched with an independent restoration contractor serving San Mateo County who carries the license and insurance the work calls for. You explain the problem once, and the right specialist is connected with you.
The contractors in the network do this work every week: pulling standing water with truck-mounted extractors, setting air movers and dehumidifiers, reading moisture behind baseboards, and cutting out wet drywall before it becomes a mold job. They know a slab leak from a roof leak, and they price the job before they start.
The line is staffed around the clock because leaks don't keep office hours. A pipe that splits at 3 a.m. on a holiday weekend gets the same routing as one that splits at noon, and if one contractor is busy, you're moved to another who covers your corner of the county.
Water does its worst work where nobody is looking. These are the signs restoration contractors say people tend to ignore until the repair bill doubles.
Below is the work contractors in the network handle most often. Tell the dispatcher which one fits, or just describe what you're seeing and they'll sort it out.
Standing water keeps soaking into drywall, subfloor, and framing for as long as it sits. Contractors arrive with truck-mounted or portable extraction units, pull water out of carpet and pad, and pump out flooded rooms so drying can start the same day.
Part of that first visit is classifying the loss: clean water from a supply line, gray water from an appliance, or contaminated Category 3 water. That call decides what can be dried in place and what has to go.
Homes take water from washing machine hoses, water heater failures, toilet supply lines, ice maker lines, and roof leaks. Residential contractors find the source, stop it, dry the structure, and then replace what can't be saved: drywall, baseboard, insulation, and flooring.
They'll photograph the damage, log readings room by room, and hand you paperwork your insurer can use if you decide to file.
Businesses lose revenue every hour the doors stay shut. Commercial contractors bring bigger equipment, including desiccant dehumidifiers and multiple extraction units, and they'll schedule around your operating hours when the space allows.
Expect containment barriers that keep dust and moisture out of unaffected suites, coordination with your property manager, and the drying logs your adjuster will ask for.
Removing visible water is half the job. Contractors set air movers to push air across wet surfaces and refrigerant or desiccant dehumidifiers to pull moisture out of the air, then check progress daily with moisture meters until materials reach dry standard.
Infrared cameras spot cold, wet areas inside walls, and drilling small holes behind the baseboard lets air into the cavity so it dries without being gutted.
Once the structure is dry, the visible repairs start: replacing sagging ceiling drywall, patching and texture matching, new insulation, baseboard, and flooring. Many contractors handle both mitigation and rebuild, so you aren't juggling two companies.
A careful crew matches ceiling texture and paint sheen so the repaired area blends into the rest of the room.
Sewage backups and outside floodwater are Category 3, meaning they carry bacteria and other contaminants. Contractors wear protective gear, remove porous materials like carpet pad and the lower section of drywall, and disinfect every surface the water touched.
Don't try to mop this one yourself, and keep kids and pets out of the area until a professional has cleaned and treated it.

Here's what to expect from the moment you call until the job wraps up.
Dial +1-323-329-3586 and tell the dispatcher what happened, where the water is, and whether it's still coming in. If you can safely shut off the main valve or breaker, do it first.
An independent contractor serving your area gets your details and confirms an arrival window. For active leaks and flooding, crews often arrive within the hour.
The contractor finds the source, measures moisture, classifies the water, and walks you through scope and price before starting.
The crew extracts water, sets drying equipment, and checks progress every day. Repairs come after the structure is confirmed dry, and the documentation stays with you.
There are plenty of names in a search result. These are the reasons people come back to this line when water shows up.

No vague estimates. The contractor explains scope and cost before any work begins, and changes get discussed with you first.
Active leaks and flooding get priority routing, and many contractors reach emergency calls in about an hour depending on distance and conditions.
Calls are routed to contractors who already work your part of the county, so you aren't waiting on a crew driving in from hours away.
The network is made up of independent contractors who carry the licensing and insurance the work calls for. Ask to see both when they arrive; a good contractor will show you without hesitation.
Contractors record photos, moisture readings, and equipment logs throughout the job, the same records insurance adjusters ask for.
If a contractor can't make it or isn't the right fit, call back and you'll be routed to another one. You should be matched with someone you're comfortable letting into your property.

Water heater burst at midnight and flooded the laundry room. The crew was there within the hour, extracted everything, and came back daily to check moisture until the drywall read dry.
We came home to the kitchen ceiling on the floor from an upstairs sink line. The quote was clear before work started, and the documentation made our claim straightforward.
A sprinkler line broke in one of our suites over a weekend. The crew sealed it off, ran dehumidifiers through Sunday, and the rest of the building opened Monday as usual.
After a storm flooded our basement, the contractor explained why the floodwater counted as contaminated, removed the lower drywall and carpet, disinfected, and dried it out properly.
A slow leak behind the shower had been rotting the subfloor for months. They found it with a thermal camera without tearing up the whole bathroom, dried it, and replaced the damaged section.
For active leaks and flooding, many contractors in the network arrive within about an hour. Exact timing depends on distance, traffic, and weather, and the dispatcher gives you an estimated window when you call.
Business Leak Detection doesn't charge you anything for the referral. The independent contractor inspects the damage and gives you a quote before starting, so you know the expected cost up front.
Contractors handle emergency extraction, flood pumping, drying setup, sewage and Category 3 cleanup, and temporary protection like tarps, 24 hours a day.
No. Business Leak Detection is a free referral service. The work is done by independent local contractors, and you agree on price and scope directly with them.
Sudden and accidental damage, like a burst pipe, is often covered, while gradual leaks and outside flooding may not be. Check your policy; contractors can provide documentation for your claim either way.
Typical drying runs about three to five days. Dense materials like hardwood and concrete slabs can need more time, which is why moisture readings, not the calendar, decide when it's done.
Shut off the water at the main valve, turn off power to wet areas if you can reach the breaker safely, move valuables and electronics out, and take photos for insurance.
Box fans help a little with the surface, but they don't reach water trapped behind drywall or under flooring. That hidden moisture is where mold starts.
Under the right conditions, mold growth starts in one to two days. Getting materials dry quickly is the best prevention there is.
They do. Commercial calls for offices, stores, restaurants, and apartment buildings are routed to contractors with the larger equipment and crews those jobs need.
It is. Calling and being matched costs nothing; payment is between you and the contractor for the work you approve.
Always. Contractors in the network are independent businesses, so ask for proof of licensing and insurance before work starts. A reputable pro will have it ready.
The network covers single-family homes, apartments, condos, townhomes, and commercial buildings in San Mateo County. Whether you're in a downtown high-rise or a house at the edge of the county, calls go to the closest available contractor.
Water damage looks different depending on the building. Older homes with plaster walls and crawl spaces dry differently than newer slab construction, and contractors familiar with local building styles know what to check first.
From the county seat out to unincorporated areas, contractors serving San Mateo County respond to homes, farms, and businesses alike. Rural properties on wells and septic systems get the same routing as in-town addresses.
Because drives across a county can run long, calls are matched by distance first. The nearest available contractor gets the job, which keeps arrival times down for outlying addresses.

The faster drying starts, the less you end up replacing. One call to +1-323-329-3586 connects you with an independent local pro, any hour.
