Stop the water, wipe up what you can, and call (413) 603-1274. Hardwood absorbs water from the edges and the underside. The first day decides whether the floor can be saved.
What water does to hardwood
- Cupping: board edges rise above the center because the underside got wetter than the top
- Crowning: the center rises, often after the floor was sanded while still wet
- Buckling: boards lift off the subfloor where they swelled against each other or the wall
- Dark stains around nails and seams
- Gaps later, when boards shrink back unevenly
Mild cupping often flattens when the floor and subfloor are dried slowly and properly. Buckled boards and black stains usually mean replacement of those sections.
What to do now
- Stop the water at the source or the main.
- Remove standing water with towels or a wet vac. Do not use a steam cleaner or heat gun.
- Pull rugs and furniture off the wet area.
- Do not sand or refinish a wet floor. That causes crowning later.
- Call us. (413) 603-1274.
How we dry hardwood
- Fix the leak first, on the same visit.
- Measure the wood and subfloor. A wood moisture meter tells us how deep the water went and gives a dry reference from an unaffected room.
- Extract surface water.
- Dry from the top and below. Floor drying panels draw moisture out of the boards, dehumidifiers keep the room dry, and where there is a basement or crawl space below, we dry the subfloor from underneath too.
- Dry slowly enough. Forcing it with heat cracks and splits boards.
- Wait for the readings. Then decide what needs sanding, repairing or replacing.
Hardwood in Chicopee homes
A lot of Chicopee houses built before 1960 still have their original oak or maple floors over board subfloors. Those floors are worth saving, and they can often be dried in place. The risk is water that runs between the boards into the subfloor and the ceiling of the unit or basement below. In two- and three-deckers we check both sides of the floor. See structural drying.
Cupping, crowning and buckling
| What you see | What it means |
|---|---|
| Cupping: board edges higher than the centers | More moisture under the boards than on top. Common after a leak. Often improves with proper drying |
| Crowning: board centers higher than the edges | Usually from sanding a cupped floor too soon, before it was dry |
| Buckling: boards lifting off the subfloor | Severe swelling. Boards may need to be removed and replaced |
| Dark stains or black spots | Water reacting with the wood or a finish problem. May need board replacement or sanding |
Solid wood, engineered and laminate
Not every wood-look floor behaves the same way. Solid hardwood, common in older Chicopee homes, can often be dried in place and refinished. Engineered wood has a thin wood layer over plywood, and that layer can delaminate if it soaks too long. It can sometimes be dried but cannot be sanded as deeply. Laminate and many vinyl plank floors trap water underneath and the core of laminate swells and does not recover, so they are usually replaced if water gets under them.
Waiting before refinishing
Even after a floor looks flat, give it time. The wood should match normal moisture readings for your house, and the subfloor should be dry too, before any sanding. That can take a week or more after the drying equipment leaves. Rushing it is the most common way a saved floor gets ruined.
What not to do with a wet wood floor
- Do not leave rugs, furniture pads or plastic on it. They trap water
- Do not turn the heat way up to "bake" it dry. Fast surface drying can crack and split boards
- Do not sand or nail down cupped boards right away
- Do not use a steam mop or soak it again while cleaning
Wipe up standing water, take photos, and get drying started. See structural drying and how to tell if water is still inside.
Hardwood questions
Will cupped hardwood go back to flat?
Often, if the floor and subfloor are dried properly and it is given time. Sanding too early locks the damage in.
How long does hardwood take to dry?
Usually longer than the rest of the room: several days to a couple of weeks depending on how much water went under it.
Is engineered wood or laminate different?
Yes. Laminate and many engineered floors swell at the core and usually cannot be dried back. The subfloor under them still needs drying.
Does insurance cover hardwood damage?
Usually if the leak was sudden. Insurers often pay to dry first and replace only what cannot be saved. See burst pipe insurance.
