Kona low flood water extraction is the removal of standing storm water from a building in Honolulu, Honolulu County, HI. Crews are dispatched 24/7 as soon as one is free. Water comes out before drying starts, because a floor still under water cannot dry and the wet materials keep taking on moisture.
A kona low is a storm that forms north of the islands and pulls tropical moisture across Oahu. The National Weather Service Honolulu office reports that the December 2021 kona low brought five to ten inches of rain across the island, with peaks of ten to 13 inches, and that flooding hit the south side especially from Pearl City to Kahala. When that kind of water reaches a home or a shop in Honolulu, the first job is taking it out, since drying cannot start on a floor that is still under water.
Flood water is not the same as a leaking pipe. It arrives from outside, from the street, the yard or a drain that cannot take the rain, and it carries mud, silt and whatever it passed over. The crew treats that water as contaminated until the site has been assessed, which is why the first visit looks at the path the water took before a pump is set. That check protects the people in the building and the materials that can still be saved.
Honolulu Water Damage Restoration takes flood calls at any hour on (833) 490-5225. A crew is sent as soon as one is free, and the phone team does not promise an arrival time, because a storm produces many calls at once. While you wait, keep people out of the water and keep electrical equipment away from it. The safety section below explains what else to avoid.
Do not walk into standing flood water in the dark, without shoes or with bare feet, and keep children and pets out of it. Do not switch on, plug in or unplug electrical equipment that is wet or standing in water, and do not use the building's power until an electrician or technician has confirmed it is safe. Do not run a household vacuum through standing water; wait for the crew's equipment. If you smell gas or see sparks, leave the building and call emergency services from outside.
The phone team asks which floor the water is on, how deep it stood, whether it is still rising and whether anyone is still inside. Those answers decide how many crew members and how much pumping the first visit needs. Do not wait for a callback before moving people out of harm's way.
Before any equipment goes in, the technician confirms the structure is sound and that power to wet areas is off. Where water reaches outlets, the service panel or wiring, the crew keeps clear of it until an electrician has checked the system. The check is made first because the building may be stressed by the water.
Submersible pumps and wet vacuums take out the standing water first, because a floor that still holds water dries slowly and leaves residue behind. The crew works from the lowest point of the space toward the exit, so the water has a clear route out. The volume removed is noted on the visit record.
Carpet pad, subfloor, baseboards and the lower wall cavity are tested with a moisture meter at several heights. The crew sorts each material into dry in place, dry with a plan, or remove, and explains the reason before tear-out begins. A material that looks clean can still hold moisture below its surface.
Air movers and dehumidifiers are placed to a plan built from the readings, and the readings are logged on every visit. The homeowner receives a written record of what was measured, what was removed and what comes next. That record is what an insurer or a contractor will ask for later.
Standing water should come out as soon as the building is safe to enter, because wet floors and walls take on moisture and odor quickly. The crew is sent as soon as one is free, and the timing follows the storm, not a fixed schedule. Honolulu Water Damage Restoration does not promise an arrival time.
A storm can flood many addresses at the same time, so the order of the calls is set by the risk on each site. The caller can say who is inside, and the phone team passes that to the crew. A building with only a shallow puddle on a concrete floor is not the same as one with water above the baseboards.
What you can do while you wait matters more than the clock. Move dry items up and off the floor, keep pets and children out of the water, and photograph the water line on the walls and the furniture. Those photographs are the first record of the loss, and they are free.
A kona low flood brings outside water that carries silt, debris and sometimes sewage, and it can cover many buildings on the same street at once. A burst pipe brings clean water from inside. The two need different handling, so the crew checks the source before choosing the cleaning and drying steps.
Because the water comes from the ground or the street, it can reach the inside of a building through doors, vents and low openings. The crew looks for the line the water left on each wall and works from that line. A clean supply-line leak usually stays in one room, while flood water tends to spread and to leave a deposit behind as it dries.
The storm pattern also matters. The March 2026 kona storm was slow-moving and brought flash flooding mainly around Oahu, on ground that was already saturated. Saturated ground cannot take more rain, so water that would normally soak into the yard runs toward the building, and the crew treats the site as a flooded site, not a single leak.
Porous materials that were in contact with flood water, such as carpet pad, loose insulation and some drywall, often have to come out. Solid wood, tile and sealed surfaces can often be cleaned and dried in place. The decision is made on readings and inspection, and the reasons are explained before anything is removed.
Carpet and pad that have been under flood water usually hold silt and moisture that drying alone cannot fully clear. Hardwood can sometimes be dried in place if it has not swelled or cupped, and the crew checks it at several points. Tile and sealed concrete are cleaned and dried, and their grout and seams are inspected for any residue left by the water.
Drywall is the most common surprise. It can look dry on the face and still hold moisture in the back. The crew cuts a small opening to check the cavity when the readings are high, and it removes only the board that the readings and the inspection justify. The homeowner sees the readings before any board comes down.
The crew handles flood water and removed material under its own procedure, because the water can carry contaminants. The homeowner is told what was removed, how much and where it went. Drying equipment is then set to a plan that the readings support.
Removed material is bagged or loaded as it comes out, so the work area stays clear and the material does not spread silt through the rest of the building. The crew records the volume and the type of each item, which helps when a claim or a receipt is needed later.
The record does not replace an inspection by a qualified person when a building was flooded. If the water reached the electrical panel, the gas appliances or the structure, the homeowner should ask for those systems to be checked before they are returned to service.
Tell the crew which floor the water reached, how high it stood, whether it is still moving in, and what it passed through on the way in. Name anything that was electrical, stored chemicals or medical equipment. Those facts decide the safety steps and the order of the work.
Show the crew the entry point the water used and any door or vent that let it in. A line of mud on a step or a debris pile against a fence tells the crew where the water came from, and that helps decide whether more water may still arrive during the same storm.
If you have a photograph of the room before the water came in, keep it. It shows the crew what was there before, which helps decide what was damaged and what was already worn. Keep your own receipts for the items you move or discard, because the record is easier to build while the room is still open.
A first visit to a flooded room is usually a matter of hours, not days, because the first job is removing the standing water. The time grows with the depth of water, the size of the space and the number of rooms affected. The crew explains the expected steps before work starts.
Pumping and wet-vacuuming a single room can be quick, but the readings and the inspection take longer than many people expect. The crew does not skip them to save time, because a missed wet cavity is the most common reason a dried room smells again later.
After the first visit the drying equipment often stays for several days, with readings taken on each return visit. The equipment is removed when the readings show the materials have reached the drying target the plan set, not when a set number of days has passed.
Storm water that comes in through a front door, a garage opening or a low threshold usually sits deepest near the entry and runs toward the back of the house. The crew starts at the entry, clears the lowest point first and checks the rooms behind it. Silt tends to settle near the walls, so the baseboards and the bottom of the wall are opened and checked.
A garage or a lower-level room often takes the most water because it sits at the lowest point of the property. Stored items on the floor, shelving and the slab edge all need to be checked. The crew moves the water toward a drain or the exit, removes the saturated items that cannot be dried, and reads the wall where the slab meets the framing.
Flood water that reaches a water heater, an air handler or a utility closet carries a second problem, because the equipment cannot be run until it is checked. The crew keeps power off to that equipment and notes it on the first visit. The equipment is left for a qualified person to inspect before it is used again.
Water that rises above the lowest wall wicks into drywall and insulation for some distance above the waterline. A stain at the baseboard can hide damage higher in the cavity. The crew opens the wall where the moisture reading is high, dries the cavity from the inside, and only then decides whether any board must be replaced.
Honolulu storms have a pattern of their own. The December 2021 kona low flooded the south side of the island from Pearl City to Kahala, and the NWS Honolulu office reports that an Iwilei power substation was flooded, cutting power to downtown businesses and residents. A flood in Honolulu can therefore mean a building has lost power as well as water, and the crew checks electrical systems before anything is turned back on.
Kona low storms return to Oahu. The NWS Honolulu office lists a February 2023 event with two kona lows, a May 2024 late-season kona low that caused mostly street flooding and a rockslide near the Pali Highway tunnels, and a late November 2023 storm with minor flooding. Each storm arrives on a different schedule, so a flood call can come at any time of the year.
The flood advisory for Oahu issued on October 7, 2026, followed a low north of the islands drawing tropical moisture over the island. A repeat of that pattern means a building that dried out after one storm can take water again soon after. The crew leaves the drying plan in place and tells the homeowner which readings to watch between visits.
A crew is dispatched as fast as one is available, and you approve the estimate before any work starts.

A water damage restoration quote in Honolulu, Honolulu County, HI depends on how much water there was, how much of the building it reached, which materials must come out, and how hard the access is.
Kona lows are storms that bring heavy, long-lasting rain to Oahu.
This site covers twelve Oahu communities in Honolulu County, Hawaii, which the fact sheet records as unincorporated census-designated places within the City and County of Honolulu, at medium confidence.
A water damage claim in Honolulu, HI is decided by the homeowner's policy and the insurer, not by this site.
Crews are dispatched 24/7 as fast as one is available, so a same-day visit is possible but never promised. Storms bring many calls at once. The phone team will tell you what to do while you wait, and the crew explains the next steps when it arrives.
A household pump that is plugged into an outlet in a wet room is a shock risk, so do not use one there. Moving dry items up and out of the water is safe to do. Leave the pumping and the drying to the crew, which has equipment built for standing water.
Not always. Carpet that was under flood water often has to come out because silt and moisture sit in the pad. Carpet that only got a wet edge can sometimes be lifted and dried. The crew makes that call from readings and tells you why before it removes anything.
Hawaii generally requires a contractor license for a project above $1,500 in labor and materials under HRS Chapter 444. Ask whoever comes to the door for their license details, and check them yourself with the DCCA Licensing and Business Registration lookup at businesscheck.hawaii.gov.
They are not the same, but flood water can carry contaminants from the ground, the street and drains. The crew treats the water with caution until the source is known, and it tells you what it found and how it is handled.
Your policy decides that, not this page. Water that comes in from outside is often handled differently from a leak inside the home in standard homeowners policies, so read your policy and ask the insurer directly. Keep photographs and the crew's written record in case you need them.
Move dry items out of the room if you can do it safely. Wet upholstery, mattresses and cardboard often cannot be dried well and may have to be removed. Photograph each item and keep the list, because the record helps with any claim.
