Subfloor problems we fix in Tinley Park kitchens
Kitchens are where leaks hide: under the dishwasher, behind the fridge water line and below the sink base. Our Tinley Park carpenters open the floor, trace the moisture to its source, replace what is damaged and reinforce framing where it needs it.
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.
Rot found during a remodel
Discoloration and soft wood under the old flooring are dealt with right away. Building over rot means problems under the new floor.
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.
Soft spot in front of the dishwasher
That spongy patch near the dishwasher is one of the most common subfloor repairs we do. The leak gets fixed first, then the damaged panel comes out.
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.
What we check and fix
- Finding and stopping the leakWe look for the source — dishwasher, sink, fridge line or an outside wall — and make sure it is fixed first.
- 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.
- Cutting out damaged subfloorWe remove the damaged area in a clean rectangle with every edge supported.
- Joist inspection and reinforcementWet, cracked or undersized joists are sistered or blocked; structural work goes through a permit where required.
- New subfloor panelsTongue-and-groove plywood or OSB of matching thickness, glued to the joists and screwed down.
- Leveling and flatteningWe level the patch to the rest of the floor and check it with a straightedge.
- Ready for flooringWhen we leave, the base is flat, dry and fastened, whoever installs the flooring on top.

Kitchen Subfloor Repair questions from Tinley Park homeowners
Do cabinets have to come out?
Most repairs stop at the cabinet face. If the subfloor under a sink base is rotted, that cabinet comes out briefly.
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?
In a room with a dishwasher and sink, plywood is the safer choice.
Can a subfloor be repaired or does it need replacing?
Sound wood is secured; damaged wood is replaced. We show you which is which.
Can you fix squeaks without tearing up the floor?
Sometimes. Access from below makes it possible; from above, special screws through carpet or wood can help in some cases.
Tinley Park building permit for kitchen subfloor repair: where do I apply?
Permits go through Building Department (Community Development), phone 708-444-5100. When your scope needs one, we prepare the application and schedule the inspections.
