When water is coming through a ceiling or spreading across a floor, the first hour decides how much of the building you save. Call +1-323-329-3586 and get connected with a licensed, insured independent water damage contractor who can reach your property in St. Louis County fast, day or night.


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 St. Louis 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.
Water damage rarely waits for business hours, so neither does the line. Nights, weekends, and holidays get the same response as a Tuesday morning, and if the first contractor is tied up, the call moves to the next one covering your part 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.
The longer water stands, the deeper it wicks into walls and framing. Crews show up with truck-mount extractors, submersible pumps, and weighted extraction tools that squeeze water out of carpet and pad, so the drying phase starts hours sooner.
Before extraction, the contractor classifies the water as Category 1, 2, or 3 based on its source, because clean supply-line water and sewage backflow get handled very differently.
Most residential calls trace back to a handful of culprits: a split washer hose, a failed water heater tank, a cracked toilet supply line, or roof flashing that let go. The contractor finds and stops the source, dries what can be dried, and rebuilds what can't.
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.
They're used to working with property managers, building engineers, and multiple tenants, and they section off affected areas with containment so the rest of the building keeps running.
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.
Ask about texture and paint matching on ceilings and walls; a good repair shouldn't leave a visible patch.
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.
Keep everyone, especially children and pets, away from the affected area until it has been cleaned and disinfected by a pro.

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.
Your call goes to an independent restoration contractor nearby who confirms an arrival time. Emergency calls get priority, and many crews reach the property in about an hour.
The contractor finds the source, measures moisture, classifies the water, and walks you through scope and price before starting.
Extraction and drying begin with daily moisture checks. Once materials are dry, repairs follow, and you keep photos and readings for your records or insurer.
You could search and call contractors one by one at 2 a.m. Here's why people call this line instead.

No vague estimates. The contractor explains scope and cost before any work begins, and changes get discussed with you first.
Emergency calls jump the queue. Arrival depends on traffic and weather, but crews commonly reach active leaks within roughly an hour.
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 the first match doesn't work out, call the line again and you'll be connected with a different contractor. A good match is the whole point of the service.

Our water heater let go in the garage around midnight and ran into the laundry room. The contractor showed up in under an hour, had the water out by 2 a.m., and set fans and a dehumidifier. He showed me the moisture readings every day until it was dry.
A supply line under our upstairs sink failed while we were at work, and part of the kitchen ceiling came down. The contractor walked us through the quote before touching anything and took all the photos our insurer wanted.
I manage a small office building and a sprinkler head got knocked loose on a Saturday. They put up plastic containment, worked through the weekend, and we opened Monday with only one suite blocked off.
Our basement took water after a heavy storm. The contractor explained it was Category 3 because it came from outside, cut out the bottom two feet of drywall, treated everything, and it's stayed dry since.
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.
Emergency calls get priority routing, and crews commonly reach the property in roughly an hour. You'll get an arrival window on the phone so you know when to expect them.
The call itself is free. Pricing comes from the contractor, who assesses the job and explains the cost before any work begins.
Water extraction, emergency pumping, board-up and tarping after storms, structural drying, sewage cleanup, and leak source location are all handled around the clock.
We're a referral line, not a contractor. Every job is performed by an independent professional, and you deal with them directly on pricing and terms.
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.
Most structures dry in three to five days with professional equipment, though hardwood, plaster, and concrete can take longer. Contractors measure daily rather than guessing.
Stop the source at the main shutoff, kill the breaker for affected rooms if it's safe, lift furniture off wet carpet with foil or blocks, and photograph everything.
Household fans move air at the surface but can't pull moisture out of wall cavities or subfloors. Without dehumidification and moisture readings, materials can look dry and still grow mold.
Under the right conditions, mold growth starts in one to two days. Getting materials dry quickly is the best prevention there is.
Yes. Many contractors in the network handle offices, retail spaces, restaurants, warehouses, and multi-unit buildings, including after-hours work and containment.
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 St. Louis 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.
Local knowledge matters here. A contractor who works your area knows whether homes usually sit on slabs, basements, or crawl spaces, and what that means for where water hides.
St. Louis County calls cover towns, suburbs, and rural roads. Properties on wells and septic systems are common outside town limits, and contractors who work the county know how those systems affect a water loss.
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.
