Floor Water Damage from Burst Pipes

How each flooring material responds to water

Solid hardwood

Hardwood cups (edges rise) when the bottom of the plank absorbs water faster than the top. If we extract and dry within 48 hours, cupping often reverses as the plank equalizes. We use specialized drying mats that pull moisture directly out through the plank surface with vacuum. Beyond 48 hours, the cupping may become permanent and crowning (opposite warp) can develop if drying is too aggressive. Original old-growth pine floors common in 1920s Minneapolis bungalows dry well; modern engineered hardwood is less forgiving because the top layer is thin.

Engineered hardwood

Engineered flooring has a plywood core with a hardwood veneer. The core can delaminate from prolonged water exposure. Partial salvage is possible for short-duration exposure; sustained wetting means replacement.

Laminate

Laminate flooring is a photographic image over MDF or HDF core, with a wear layer on top. It's water-resistant on the surface but not waterproof at the seams. Water that penetrates the seams gets into the core, which swells permanently. Full replacement is almost always the right call.

Luxury vinyl plank (LVP) and sheet vinyl

LVP is waterproof; the planks themselves don't absorb water. The problem is water getting under the planks into the subfloor. We lift sections for subfloor drying, then re-lay. Sheet vinyl behaves similarly — water doesn't damage it but it traps water underneath.

Carpet

Face fiber: usually savable with extraction and dry-in-place if Category 1 water and quick response. Pad: usually removed and replaced because it holds water and prevents subfloor drying. We lift carpet at a seam, remove pad, dry the subfloor, replace pad, and re-stretch and re-tack the carpet.

Tile

Ceramic and porcelain tile are waterproof. The problem is water that seeped through grout lines and sits between the tile and the subfloor. We extract through unsealed grout lines or at the perimeter and dry the subfloor beneath. Grout haze and discoloration can usually be cleaned.

Concrete and stained concrete

Concrete doesn't take water damage in the traditional sense but holds moisture that migrates into adjacent materials (wall base plates, trim, flooring installed over concrete). We dry the concrete to a verified moisture content before any reinstallation on top.

Subfloor assessment

The subfloor is often the most important material in a floor-damage loss because what goes on top of it next is expensive. Plywood subfloor usually dries in place with proper air movement and dehumidification; OSB subfloor swells more and is less forgiving but can often be dried if addressed quickly. We verify subfloor moisture content with pin meters before any flooring work goes back in place.
