Subfloor problems we fix in Batavia kitchens
Kitchens are where leaks hide: under the dishwasher, behind the fridge water line and below the sink base. Our Batavia carpenters open the floor, trace the moisture to its source, replace what is damaged and reinforce framing where it needs it.
Leak from the refrigerator water line
When the floor behind the refrigerator is dark or soft, the water line is the first suspect. We fix both.
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.
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.
Squeaks and creaks underfoot
Squeaks happen when the subfloor moves against nails or joists. We fasten it down with screws, add construction adhesive or install blocking where it is loose.
Rot found during a remodel
Pulling up old vinyl often uncovers dark, crumbling plywood. We cut it out to sound wood, treat the cause and install new panels before the new floor goes down.
Spongy floor at the sink base
Drips from supply lines or a drain connection run down into the cabinet floor and the subfloor below it. We check both and replace whatever has softened.
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.
Where we look first
- Finding and stopping the leakWe look for the source — dishwasher, sink, fridge line or an outside wall — and make sure it is fixed first.
- Moving appliances and cabinetsWe clear access to the damaged area, including under cabinets when needed.
- Cutting out damaged subfloorSoft and rotted sections are cut back to sound wood, ending on joist centers or new blocking.
- Joist inspection and reinforcementWe check the framing beneath and reinforce it when it is damaged or too flexible.
- New subfloor panelsNew panels set flush with the existing floor and fastened with construction adhesive and screws.
- Leveling and flatteningWe level the patch to the rest of the floor and check it with a straightedge.
- Ready for flooringThe repaired area is left ready for tile, plank or wood, and appliances go back when the floor is finished.
Parts we replace
Tongue-and-groove plywoodThe usual choice for kitchen subfloors: stiff, holds screws well and tolerates brief wetting better than OSB.
Underlayment layerA thin top layer that adds stiffness or a smoother surface.
Construction adhesive and subfloor screwsFastening that grips the joists instead of working loose like nails.
OSB panelsEngineered strand board, used to match an existing OSB floor.
Leveling compound and patchFlattening products for small dips and seams.

Kitchen Subfloor Repair questions from Batavia homeowners
Why is the floor soft by my dishwasher?
Almost always water. A leaking hose, drain connection or door seal soaks the subfloor until it softens. The leak has to be fixed along with the floor.
How do you find where the leak is coming from?
The wettest wood usually points to the source. We test connections and confirm it before closing the floor.
Do I need a permit for subfloor repair?
For framing repairs, often yes. For a panel patch, usually no. We confirm before starting.
Who should I call for subfloor repair?
Call a contractor that does subfloor and framing work, not just flooring. We repair the base and can install the new floor.
Can you replace just a section of subfloor?
Usually, yes. Partial replacement is normal as long as the edges are properly supported.
Batavia building permit for kitchen subfloor repair: where do I apply?
Permits go through City of Batavia Community & Economic Development - Building Division, phone 630-454-2700. When your scope needs one, we prepare the application and schedule the inspections.
