Floor too thin for tile
Tile needs a stiffer base than vinyl. We add a layer of plywood or reinforce the framing before a tile floor goes in.

Subfloor problems we fix in Glendale Heights kitchens
A soft spot in front of the dishwasher or sink usually means water has been reaching the wood under the floor for a while. In Glendale Heights we find and stop the leak, cut out the damaged subfloor, check the joists and install new panels that are glued and screwed down.
Squeaks and creaks underfoot
Noisy floors are usually loose, not broken. Re-securing the panels to the framing quiets them.
Musty smell or stains in the basement ceiling
Water stains on the basement ceiling below the kitchen can point to a leak above. We check the subfloor from both sides.
Cracked tile or separating plank floor
Tile that cracks and click-lock floors that gap at the seams are often reacting to a subfloor that flexes or isn't flat. We fix the base so the finish floor stops failing.
Damage at a seam from a past repair
Old subfloor repairs are often the weak spot. We rebuild them so the edges are fully backed.
Uneven or out-of-level floor
A floor that rolls under a straightedge needs flattening before new flooring. We choose between leveling the framing and leveling the surface.
Soft spot in front of the dishwasher
When the floor gives under your foot at the dishwasher, the plywood has probably absorbed water. The fix is cutting out the soft area back to solid wood.
Bouncy or sagging floor
Bounce in the middle of the kitchen often comes from the framing, not the plywood. Sistering or adding blocking stiffens it.
What we check and fix
- Finding and stopping the leakNo new subfloor goes in until the water that ruined the old one is stopped.
- Moving appliances and cabinetsThe dishwasher, fridge or range comes out, and toe kicks or a sink base are removed if the damage runs under them.
- Removing the finish floorTile, vinyl or wood is taken up over the damaged area, with the cut planned so the floor can be patched cleanly.
- Moisture testingA moisture meter shows how far the wet wood extends and whether the framing is dry enough to close.
- Cutting out damaged subfloorWe remove the damaged area in a clean rectangle with every edge supported.
- Joist inspection and reinforcementJoists under the opening are probed for rot and cracks; weak ones get new lumber fastened beside them.
- Ready for flooringThe repaired area is left ready for tile, plank or wood, and appliances go back when the floor is finished.
Common fixes and parts
Sister joists and blockingFraming reinforcement that stiffens the floor and backs every seam.
Underlayment layerAn extra plywood or backer layer that stiffens the floor for tile or smooths it for vinyl.
OSB panelsEngineered strand board, used to match an existing OSB floor.
Construction adhesive and subfloor screwsGlue and screws together keep the subfloor from moving and squeaking.
Tongue-and-groove plywoodThe usual choice for kitchen subfloors: stiff, holds screws well and tolerates brief wetting better than OSB.

Who should I call for subfloor repair?
