Water damage restoration that dries the house, not just the surface

Why a floor that looks dry can still be wet

Water moves sideways and downward faster than most people expect. A dishwasher leak that left a puddle in the kitchen often has wet subfloor under the cabinets, soaked drywall a foot up the wall behind the toe kick, and damp insulation in the room below. The visible surface dries in a day; the materials behind it hold their water for much longer. That hidden moisture is what warps hardwood, delaminates cabinet bases and lets mold start.

So the first visit is mostly measuring. A moisture meter on the drywall, baseboards and flooring shows where the water went, and a thermal camera can point to cold, damp patches worth checking with the meter. We mark the edge of the wet area on a sketch of the room and photograph it. That map becomes the drying plan, and later it shows the adjuster why a wall was opened in one place and left closed in another.

Clean, gray or black: why the source of the water matters

The IICRC's S500 standard for water damage restoration sorts water into three categories by contamination, and the category changes what can be saved. Water from a broken supply line or a leaking water heater usually starts as the cleanest kind. Discharge from a washing machine or a dishwasher carries more contamination. Sewage and rising water from rivers or streams are the most contaminated category, where porous materials it touched are generally removed rather than dried. Water does not stay in its first category forever: time, warmth and contact with dirty materials make it worse, which is one more reason the first days matter. Our article on water damage categories explains each one with examples, and sewage cleanup covers the worst case.

What we do on a water damage job

1. Stop and protect. Confirm the source is shut off or fixed, move furniture and boxes out of the wet zone, and set blocks or foil under legs that must stay.
2. Extract. Pull standing water from carpet, pad and hard floors with extraction equipment; it is far quicker than drying it out of the air.
3. Open what traps water. Remove baseboards, drill or cut drywall where water is sealed behind it, and lift pad or flooring that cannot dry in place.
4. Dry to a target. Set air movers and dehumidifiers, then take readings on each visit until the materials match a dry reference reading from an unaffected part of the house.
5. Clean. Clean and, where the water category calls for it, treat the surfaces that remain.
6. Rebuild. Put back drywall, flooring, cabinets and paint once the readings say the structure is dry.

The order matters. Closing a wall or laying new floor over materials that are still wet is how a finished repair ends up with a musty smell or cupped boards months later. The reconstruction after damage page covers the rebuild half of the job.

How long does drying take?

There is no honest single number. Drying time depends on how much water there was, how long it sat, what the materials are, and the weather: a dense hardwood floor over a concrete slab dries differently from carpet over plywood, and a humid week slows everything. What you should expect from any restorer is a plan with readings: where the wet materials started, where they are on each visit, and what reading counts as dry. If someone pulls the equipment without showing you that the numbers reached the target, ask why.

What you can do before we arrive

• Shut off the water at the main valve if the leak is still running, and switch off power to wet rooms at the breaker only if you can reach the panel without standing in water.
• Take photos and video of every wet room, close-ups and wide shots, before you move anything.
• Lift rugs, curtains and anything on the floor that can be carried, and put foil or plastic under furniture legs.
• Move papers, photos and electronics to a dry room; do not try to dry electronics by switching them on.
• Keep receipts for anything you buy to stop the damage, such as towels, a wet vacuum or a tarp.

Our step-by-step guide what to do after water damage covers the first day in more detail, including what not to throw out before the adjuster sees it.

Leaks we see in the Bay Area and around Dallas–Fort Worth

In Bay Area homes, a lot of water damage comes from inside: supply lines under sinks and toilets, ice maker lines behind refrigerators, water heaters at the end of their life, and slow shower pan leaks that show up as a stain on the ceiling below. Winter storms add roof leaks and water in crawl spaces. In Dallas–Fort Worth, a hard freeze can split pipes in exterior walls and attics, and the water often appears only when the pipe thaws. Hail and wind-driven rain are a second large group, covered on our storm damage repair page.

When water damage turns into a mold job

The EPA advises drying water-damaged areas and items within 24 to 48 hours to prevent mold growth, and says porous materials such as ceiling tiles and carpet may have to be thrown away if they become moldy. If a leak went unnoticed for a while, or materials stayed wet behind a wall, a water job can become a mold remediation job, with containment and removal before any drying makes sense. We tell you which one you have before work starts, and in Texas we explain how the state splits mold assessment and remediation between separate licensees.
