Why does wet hardwood cup, and can it flatten again?
Hardwood cups when moisture enters the bottom of the board more than the top, so the edges rise. Once the board dries evenly, it can sometimes flatten, but severe swelling or long exposure can leave it permanently distorted. The crew reads the boards over several visits to see whether they are recovering.
A board that is wet on one face and dry on the other will curl. The effect is strongest where the water sits longest, which is often the middle of a room or the edge near a wall. The drying is aimed at the underside of the boards, through the subfloor, as well as the surface.
Some boards recover well, and some do not. A board that has lifted from the subfloor or has split along the grain is unlikely to return to its original shape. The crew explains which boards it expects to recover and which it expects to replace, and it notes the readings that support the decision.
Can carpet be dried and put back, or should it be replaced?
Carpet can sometimes be dried and reinstalled if the pad is replaced and the subfloor reads dry. Carpet that has been soaked with sewage, or that holds silt or contaminated water, is usually removed. The crew explains the choice from the readings and the type of water before it decides.
Carpet backing and the fibers hold water for a long time, and they can keep the pad damp. A carpet that has been pulled and dried without the pad being dealt with can stay wet underneath. The crew checks the pad and the subfloor before it advises on the carpet.
Where the carpet is kept, the crew checks it for stains, odor and fiber damage. Where the carpet is removed, the homeowner chooses the replacement. This site does not quote a price for either option.
How does a crew dry a subfloor it cannot see?
The crew reads the subfloor from the access point where there is one, from a small opening in the floor, or from beneath the house where the space allows. Moisture meters show where the water has reached, and equipment is placed to dry the joists and the subfloor from below where it can be reached safely.
A small opening in the subfloor can give the crew a way to read the joists and to place equipment. The opening is kept as small as possible and is explained before it is made. Where the joist space is too tight to enter, the crew works from the access point and reads the readings from there.
A subfloor that is soft or rotted is noted for the homeowner. The crew does not repair the structure itself, but it records what it finds so that the carpenter or flooring trade can plan the repair from the readings.
What affects the cost of hardwood and carpet drying?
The factors are the area of floor affected, the floor covering, how far the water reached into the subfloor, and whether boards or carpet must be removed. Access to the joist space also changes the work. Each job is priced after the walkthrough, and no price is quoted over the phone.
A small room with carpet that dries in place is a different job from a whole floor of solid hardwood that must be opened. The number of rooms and the number of boards removed both change the time and the materials.
The replacement flooring is a separate cost, quoted by the trade the homeowner chooses. The crew's scope covers the water, the drying and the removal, and it is confirmed in writing before the work begins.
Should I lay down towels or fans on a wet floor?
Towels and a fan can help a small spill, but they do not dry the subfloor. Keep the floor clear, keep the air moving if it is safe, and avoid walking on soft boards. Do not put rugs or carpet back on a floor that is still wet.
A fan can dry the surface of a board and make the room feel drier than the subfloor really is. The moisture below will continue to rise until it is removed, so the readings are the only reliable test.
Avoid walking on boards that are cupped or lifting, because they can crack or spring loose. Keep furniture off the wet area, and move small items to a dry surface.
