Subfloor problems we fix in Elmhurst kitchens
The subfloor is the layer of plywood or boards that every kitchen floor depends on. We repair it in Elmhurst homes when it has gone spongy, rotted, squeaky or uneven, and we leave it flat and dry for the finished floor.
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.
Bouncy or sagging floor
Sag across the room points to the joists. Structural repairs like sistering usually need a permit, and we handle that work properly.
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.
Swollen, mushroomed panel edges
Raised lines in a floor that follow a grid usually trace swollen subfloor seams. We replace the damaged panels.
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.
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.
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.
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 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 floorThe finished surface comes up over the soft area, with a cut line that makes the later patch easy to hide.
- Moisture testingMeter readings across the area tell us where wet wood ends and when it is safe to close the floor.
- Joist inspection and reinforcementJoists under the opening are probed for rot and cracks; weak ones get new lumber fastened beside them.
- 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.
Repair options

Kitchen Subfloor Repair questions from Elmhurst homeowners
Why is the floor soft by my dishwasher?
A slow dishwasher leak is the most common cause. We pull the unit, find the drip and replace the damaged subfloor.
Who should I call for subfloor repair?
You need someone who handles both the structure and the finish floor. We do both.
How do you find where the leak is coming from?
We look at the stain pattern, check the dishwasher, sink and fridge connections and use a moisture meter to find the wettest spot.
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.
Do cabinets have to come out?
Not usually. When rot extends under a cabinet, we may remove that one section and reset it.
Does kitchen subfloor repair need a Elmhurst building permit, and who files it?
Permits go through Community Development Department (Building), phone 630-530-3030. When your scope needs one, we prepare the application and schedule the inspections.
