Subfloor problems we fix in Wheaton kitchens
The subfloor is the layer of plywood or boards that every kitchen floor depends on. We repair it in Wheaton homes when it has gone spongy, rotted, squeaky or uneven, and we leave it flat and dry for the finished floor.
Floor too thin for tile
Thin or single-layer subfloors can crack tile and grout. An added layer and solid fastening make the floor tile-ready.
Rot found during a remodel
When tear-out reveals rot, it has to be replaced, not covered. We repair it so the remodel can continue on a solid base.
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.
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.
Cracked tile or separating plank floor
When the floor above keeps breaking, the cause is often underneath. A stiffer, flatter subfloor makes new flooring last.
Swollen, mushroomed panel edges
Ridges along panel joints often mean wet OSB. Sanding doesn't fix it; the swollen sections are cut out.
What the repair visit covers
- 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.
- 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 testingWe measure the wood moisture to set the repair boundary and confirm it is dry.
- Joist inspection and reinforcementWet, cracked or undersized joists are sistered or blocked; structural work goes through a permit where required.
- New subfloor panelsNew panels set flush with the existing floor and fastened with construction adhesive and screws.
- Ready for flooringSubfloor solid and clean; we can lay the new floor or coordinate with your flooring installer.

Kitchen Subfloor Repair questions from Wheaton homeowners
Can you fix squeaks without tearing up the floor?
From an unfinished basement, yes in many cases. Otherwise the best time is when the flooring is up.
Do I need a permit for subfloor repair?
For framing repairs, often yes. For a panel patch, usually no. We confirm before starting.
Can you replace just a section of subfloor?
Yes. We cut out the damaged area back to sound wood, support every edge on a joist or blocking and fit a new panel flush with the rest.
Plywood or OSB for a kitchen subfloor?
Plywood tolerates wetting and holds fasteners well. OSB is common and fine dry but swells at the edges when wet.
How long does subfloor repair take?
It depends on how much is damaged and whether the wood has to dry. We give you a schedule with the estimate.
What is the Wheaton building department phone number?
Permits go through Building & Code Enforcement Department, phone 630-260-2050. When your scope needs one, we prepare the application and schedule the inspections.
