How fast does standing water do damage in a Syracuse basement?
Standing water begins to damage a basement in hours, not days. Carpet pad and the bottom of drywall take on water first, and the moisture then moves into the sill plate and the subfloor. The sooner the free water is removed, the less material has to come out.
Water moves into a porous surface by capillary action and through any gap at a seam. A concrete floor can look dry on top and still hold water in its pores, and that water feeds the wall base for days after the surface has dried. An experienced crew reads the concrete and the wall, not only the floor.
Wood is the material that changes the job most. A sill plate or a joist that stays wet can soften and begin to grow mold within a short time, and the damage is often hidden behind a finished wall. Pumping early is the step that keeps the wood in place.
Why do Syracuse basements flood during storms?
Heavy rain can overwhelm a basement's drainage in a few ways, including water over the curb, through a window well and up a floor drain. A local news guide to the city's flash-flood spots says intense storms push water over curbs and back sewage into basements.
The source of the water decides where it enters. Street water comes in at the lowest openings, such as a door sill, a bulkhead or a window well. Sewer water comes up through the floor drain, the laundry tub or a toilet. A crew looks for both, because the water that enters through a drain is treated differently from clean supply water.
The city's own view is that Onondaga Creek has less channel capacity than it once did, because of sediment, and that more intense short-duration storms add to the risk. That explains why a storm can fill a low basement quickly even when the creek itself is not in flood.
- Water over the curb and into a low door or bulkhead
- Window well water that runs down the wall behind the window
- Sewer water up a floor drain or laundry tub
- Water from a cracked foundation wall after a long wet spell
What does a crew do first on arrival?
The crew first checks for safety hazards, then establishes the source of the water and removes the standing water. Readings are taken at once so the drying plan starts from a known starting point.
On arrival the technician walks the path from the entrance to the wet area and looks at the power, the stairs and the panel before entering the water. If the water is near an outlet or an appliance, power is kept off until it has been checked. Protective gloves, boots and eye protection are worn for any contaminated water.
The technician then records where the water is, how deep it is and what it covers. Photographs are taken before anything is moved, so the water line and the condition of the room are on record. That record is useful to the owner and to any insurer who asks about the event later.
What should you move and what should you leave?
Move valuables, electronics and paper up off the floor if it is safe to do so, and leave heavy furniture and anything connected to power for the crew to handle. Do not wade through water to reach items in a flooded room.
Items that can be lifted easily, such as boxes, shoes and loose paper, should go to a dry room upstairs. Keep records and photographs of anything damaged, because the insurer will ask. Mark the water line on the wall with a pencil and a date, which helps the crew and the adjuster see how high the water rose.
Leave fuse boxes, extension cords and any appliance that is still plugged in alone until the power is confirmed off. Leave carpet and furniture in place until the crew has read the floor, since the readings decide what can be dried and what must come out.
How long does extraction take, and what happens after the water is gone?
Pumping and extraction usually take one visit for a shallow basement and several visits for a deep or multi-room loss. Drying continues after the standing water is gone and is measured against readings, not against how the floor looks.
The first visit is the longest. It covers the removal of the bulk water, the first readings and the placement of equipment. The crew returns on a set schedule to take new readings and to move equipment where the readings say it is needed.
Drying is complete when the readings reach a dry level, not when the floor feels dry to the touch. The owner receives the log of readings, so the progress is visible from visit to visit.
