Subfloor problems we fix in Hanover Park 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 Hanover Park we find and stop the leak, cut out the damaged subfloor, check the joists and install new panels that are glued and screwed down.
Swollen, mushroomed panel edges
Raised lines in a floor that follow a grid usually trace swollen subfloor seams. We replace the damaged panels.
Spongy floor at the sink base
If the floor dips in front of the sink, the damage often reaches under the cabinet. We open the area carefully and rebuild it.
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
A patch that dips at its edge was likely cut between joists without blocking. We open it and support it correctly.
Squeaks and creaks underfoot
From below in a basement, or from above with the flooring off, we find where the floor moves and stop it.
Uneven or out-of-level floor
Humps and dips are corrected with planing, shims on the joists or a leveling compound, depending on how far out the floor is.
Leak from the refrigerator water line
Slow leaks from fridge lines are hard to see. We pull the fridge, trace the water and repair the floor.
Where we look first
- Finding and stopping the leakNo new subfloor goes in until the water that ruined the old one is stopped.
- Moving appliances and cabinetsWe clear access to the damaged area, including under cabinets when needed.
- Moisture testingMeter readings across the area tell us where wet wood ends and when it is safe to close the floor.
- 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
Underlayment layerAn extra plywood or backer layer that stiffens the floor for tile or smooths it for vinyl.
Sister joists and blockingNew lumber fastened alongside damaged or weak joists, plus blocking that supports panel edges.
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 Hanover Park homeowners
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.
Plywood or OSB for a kitchen subfloor?
We generally prefer plywood in kitchens because it handles occasional water better. OSB is used when matching an existing OSB floor.
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.
Can you replace just a section of subfloor?
We do it often. The patch is sized to the damage and fastened to the framing.
What affects the cost of subfloor repair?
How much area is damaged, whether joists need work, removing and replacing the finish floor and moving cabinets or appliances. We give a written, itemized estimate after the visit.
What is the Hanover Park building department phone number?
Permits go through Inspectional Services Division (Hanover Park Fire Department), phone 630-823-5860. When your scope needs one, we prepare the application and schedule the inspections.
