Structural drying removes moisture from the building materials themselves after standing water has been extracted. A technician places air movers and dehumidifiers, takes moisture readings, and keeps adjusting until wood, plaster and framing read dry. In Columbus, the work runs as long as the readings require.
Water that soaks into a building does not stop at the floor. Drywall, subfloor, joists and the lath behind plaster keep moisture long after the standing water is gone. Structural drying is the stage that pulls that moisture back out of the structure, so materials can be rebuilt or left in place without trapping damp inside the walls.
Central Ohio houses make this stage harder than most. Many older city homes in Clintonville, Franklinton, Bexley and Grandview Heights have plaster on wood lath and solid hardwood over joists, and both give up water slowly. In newer suburbs the water usually lands in a finished basement, where carpet, pad and drywall hold moisture against the framing in a space that is closed off from the rest of the house.
The crew does not judge dryness by feel. It uses moisture meters and thermal imaging to find wet material, including areas behind baseboards and under flooring, then sets equipment and logs readings each day until they stop falling. EPA guidance is to dry water-damaged areas within 24 to 48 hours to limit mold, and the readings show when the job is finished.
Do not run extension cords or electric fans in standing water, and keep children and pets out of wet rooms. If the panel, outlets or the furnace are in the water, shut the power off at the main from a dry spot if it is safe, or call the utility first. Do not cut plaster, pull up flooring or remove drywall in a home built before 1980 until you have checked for asbestos and lead, since Ohio EPA and your local health district can advise on those materials. Household fans and a single dehumidifier rarely dry framing, and they can spread contaminated water if the source is still active.
Before any drying starts, the crew checks that the water source has been shut off or stopped. Drying a structure that is still taking on water wastes equipment and hides the real problem. Homeowners who can reach the main shut-off should use it first.
The technician uses moisture meters and thermal imaging to trace how far the water went. Wet material often sits behind walls, under flooring and inside the wall cavity, out of sight. The map shows where equipment must reach, and where material may need to be opened up.
Air movers push air across wet surfaces, and dehumidifiers pull the moisture out of the air. Placement depends on the room layout and the materials, since hardwood, plaster and drywall dry at different rates. Lower levels usually need more units than a single room suggests.
The crew logs moisture readings each day and compares them with the earlier numbers. Equipment is moved or adjusted where readings stall. Drying is complete when the materials stop losing moisture, not when the surface simply feels dry.
At the end of drying, the crew can give you photos and moisture readings to share with your insurer. Repairs after drying, such as drywall, trim or flooring, are quoted separately once someone has seen the wet area. The price for the emergency stage is explained and approved before work starts.
Drying runs as long as the readings say it should. The length depends on the materials wet, how deep the water went and how much air can reach them. Nobody can give an honest number of days before the first readings are taken.
Drywall dries faster than framing, and framing dries faster than a thick hardwood floor over a crawl space. A crew working on a finished basement may find the carpet pad is dry in a day while the bottom plate still reads wet. Each material is tracked separately, so the job does not end because the most visible area looks fine.
Readings are taken on a schedule, and they are compared with the day before. When the numbers stop falling, the crew knows the structure has reached a stable point. Until then, the equipment stays in place, and the homeowner can expect the job to continue rather than end on an arbitrary day.
Plaster and solid hardwood hold water in thick layers and release it slowly. Pre-war construction often leaves the wet material inside walls and under floors where air moves poorly. Drying them too quickly can cause the damage the crew is trying to prevent.
Many homes in Clintonville, Franklinton, Bexley and Grandview Heights were built with plaster on wood lath, and the plaster keys into the lath. Water can sit between the plaster and the lath for a long time. The crew checks the wall at several heights, since the wet line often runs above where the damage is visible.
Hardwood over joists in older houses can have a gap beneath it, and that gap traps humidity. The crew may lift a board or drill small holes to reach the space underneath. The point is to move air through the cavity, not to dry the top surface quickly and leave the structure wet.
The size of the wet area, the category of water, the materials and the access all change the job. The price is explained and approved before any work begins. Repairs after drying are quoted separately, once someone has seen the wet area.
A wet area that covers one room and a hallway usually takes less equipment than a finished basement that reached the furnace room, the stairs and a storage area. Water that came from a sewer backup or rising floodwater is a higher category than a clean supply-line leak, and it calls for more handling. Materials matter too: carpet and pad are often removed, and plaster or hardwood takes more care than drywall.
Access is a factor that people often overlook. A basement with stairs only, a crawl space with a small door or a third-floor apartment all change how the equipment gets in and out. Whether mold has already started turns the job into a containment job, and that is priced differently. A plumber may also need to repair the source first, and that work is not part of the drying quote.
Often it can be done with small openings, but some materials have to come out. The crew decides this from the readings, not from appearance. Materials that stay wet will not dry, so opening them is sometimes the only way.
Air movers work best when they can push air into a cavity. A technician may remove a baseboard, pull a small section of drywall or drill a few holes in a plaster wall to reach the wet framing. The openings are kept small and placed where the readings show moisture, so the wall is not opened more than needed.
Some materials cannot be dried in place. Carpet pad that has taken in sewage or floodwater usually goes, and so does drywall that is soft or crumbling. Pre-1980s homes can contain asbestos in plaster, joint compound and floor tile, and pre-1978 homes can have lead paint, so opening those materials calls for checking first. Ohio EPA and your local health district are the places to ask about those rules.
Coverage is decided by your insurer under your own policy, not by the crew. The crew can document the damage and the drying for your claim. A standard homeowners policy generally responds to sudden and accidental water damage.
Policies differ on gradual leaks, sewer and drain backup, and flood. The Ohio Department of Insurance lists water damage from a sewer backup or basement leak among typical exclusions on many homeowners forms, so that coverage often depends on an endorsement. Flood is a separate policy, through FEMA's National Flood Insurance Program or a private insurer. Check your policy or ask your agent before assuming anything is covered.
Take photos before anything is moved, and call your insurer early. Keep the readings and photos the crew gives you, and ask the company for the written agreement and the price approval before work starts. If you disagree with how a claim was handled, the Ohio Department of Insurance takes consumer complaints.
Finished lower levels in newer suburbs usually have carpet, pad, drywall and sometimes a drop ceiling over the framing. Water sits under the pad and wicks into the bottom plates and drywall, so the crew often needs to remove carpet and open the wall base to get air behind it. Readings are taken at the wall base and the subfloor, where moisture hides longest.
In pre-war houses, hardwood over joists and plaster on wood lath dry slowly, and both can be damaged by drying too fast. Hardwood cupping and plaster cracking are common when the drying is rushed. The specialty drying that the industry calls Class 4 applies to these materials, and the crew adjusts the equipment to match the rate at which each one gives up water.
Crawl spaces are the common case in the canal and crossroads villages and in the oldest housing, where the floor framing sits close to the ground. Wet subfloor and joists need airflow from below, which can mean working through a small access opening. Framing that stays wet can cause problems later, so the readings go down to the sill plates and the joist ends.
A bathroom or laundry leak on an upper floor can soak the insulation, the joists and the ceiling below before the stain appears. The crew checks the cavity above the ceiling as well as the room below. Drying the cavity matters because insulation can hold water well after the ceiling surface looks dry.
Columbus homes are built over full basements almost everywhere, which means structural drying usually happens below grade. Basement framing, sill plates and the bottom of the wall are where moisture lingers, and the water heater, furnace and panel often sit in the same space. The crew works around those appliances and keeps the readings focused on the framing and the floor.
The high water table here matters for drying. Pewamo soils in the low spots run wet from December to May, and foundation seepage in those months can leave walls and framing damp after the rain stops. A basement that never has standing water can still need drying if the wall wicks moisture in for weeks.
The 19 and 20 August 2026 rainfall, when the National Weather Service measured 4 to 7 inches in the heaviest parts of Franklin and Licking counties, left river and overland flooding that reached the lower levels of many homes. Flood water drying follows the same readings, but flood damage needs a separate flood policy to be covered. The crew can document the drying either way.

Extraction removes the standing water from floors and carpet. Structural drying removes the moisture that has soaked into the building materials after the water is gone. Both stages matter, because drywall, framing and subfloor keep moisture that a mop cannot reach. The crew explains each stage before work begins.
The crew uses moisture readings, not appearance, to decide. Drying is complete when the materials stop losing moisture on the daily readings. A wall or floor can look dry while the framing behind it is still wet. You can ask for the readings and the photos at the end of the job.
Thermal imaging shows temperature differences that often come from moisture behind a surface. It helps the crew find wet areas behind baseboards, under flooring and inside walls without opening them first. It is used together with moisture meters, since neither tool alone proves a material is dry.
It can, if the drying is rushed. Hardwood can cup or crack, and plaster can crack when it dries too fast. That is why the crew adjusts the equipment for each material. Specialty drying for hardwood, concrete and plaster exists for this reason.
Yes, where it sits on wet material. Furniture held against a wall or sitting on wet carpet blocks airflow and keeps moisture in place. Move small items to a dry area and photograph the room before anything is moved. The crew will tell you which items need to come out for the drying to work.
The crew can hand over the readings and photos, and repairs are quoted separately after someone has seen the wet area. Drywall, trim and flooring are usually rebuilt once the framing reads dry.
