Hardwood Subfloor Dry Out in Loveland, OH

Can carpet be dried in place after river water?

Carpet can sometimes be lifted, cleaned and dried, but pad that stood in river water is generally removed. River water leaves silt that the pad holds, and the pad cannot be cleaned to a safe condition once saturated.

Carpet fibres are more forgiving than the pad. Once the pad is gone, the carpet can be lifted, washed and dried over a clean surface, and if it has no stains or odour it may go back on new pad.

A carpet that was only lightly wet from a supply line can sometimes be dried in place, if the pad is dried quickly and the subfloor reads dry.

Why does hardwood cup after it gets wet?

Wood absorbs water from the underside faster than from the top, so the boards swell unevenly and curl. Once dry they may return to flat, but a long wetting or fast drying can leave them curled.

The subfloor under the boards is the main reason. If it stays wet, the boards are wet from below and keep swelling. Measuring the subfloor is the first step in deciding whether the boards can return.

Drying wood is slow on purpose. Heat and strong airflow can dry the top before the bottom, which causes checks and splits.

When does a floor need replacing?

When boards stay cupped after drying, when they have delaminated or split, when the subfloor is rotten or when the water carried contaminants that cannot be cleaned out.

Engineered wood with a thin veneer can lose that veneer after long wetting and cannot be refinished the way solid wood can, so replacement is usually the decision for those boards.

Vinyl and tile can often be kept if the subfloor is dry, but a hard surface that has been lifted may not sit flat again.

Is it safe to walk on a wet floor?

No. A wet subfloor can be weak, and a floor that has been lifted or cut is unstable. Keep off soft areas and keep children and pets away.

Carpet over wet pad can be slippery as well as soft, and cupped wood can have edges that catch the foot. Walk along the walls where the subfloor is strongest.

If a floor gives under you, step off it. Softened subfloor can break, and the damage underneath is often larger than the spot that gave way.

Is a fan enough?

A fan helps the surface, but it does not reach the pad or the subfloor. If the carpet is wet to the pad, the pad has to come out.

Running a fan over wet carpet can make the top look dry while the pad keeps the water. A homeowner who relies on that look can wait too long.

Use a fan as an addition to the readings, and keep the room closed off from the rest of the building while it runs.

Lifting boards and reading the subfloor

Boards are lifted only where needed, and the subfloor is read through the gaps.

Hardwood that has taken water cups or swells, and the boards cannot always be saved. The crew lifts boards in a pattern that lets it reach the subfloor, and it reads the subfloor through the gaps. The lifted boards are numbered so they can be put back if they are saved.

Where boards are too damaged to save, they are removed and logged. The subfloor is read at each joist bay, and the readings decide when the floor can be closed.

• Number the boards as they are lifted
• Read the subfloor at each joist bay
• Log boards that cannot be saved
• Dry the subfloor to target before closing the floor
• Record the readings on each visit

Choosing between saving and replacing

Saving a floor depends on the readings and the state of the boards, and the decision is written down.

Whether a hardwood floor can be saved depends on how long it was wet, how much it cupped and whether the subfloor is sound. Boards that dry flat may be saved, and boards that stay swollen usually cannot. The crew records its view, and the homeowner decides with a flooring trade.

The decision is written into the scope with the reason. That keeps the choice clear for the insurer and for the trade.

• How long the floor was wet
• How much the boards cupped
• Whether the subfloor is sound
• The decision and its reason, in writing
• The flooring trade's view, if it is given
