Subfloor problems we fix in Downers Grove kitchens
The subfloor is the layer of plywood or boards that every kitchen floor depends on. We repair it in Downers Grove homes when it has gone spongy, rotted, squeaky or uneven, and we leave it flat and dry for the finished floor.
Soft spot in front of the dishwasher
When the floor gives under your foot at the dishwasher, the plywood has probably absorbed water. The fix is cutting out the soft area back to solid wood.
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.
Musty smell or stains in the basement ceiling
Signs from below often show up first. We trace them to the source and repair what is wet.
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.
Leak from the refrigerator water line
A weeping ice-maker connection behind the fridge can soak the floor for months. We replace the line or valve and the damaged subfloor under it.
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.
What the repair visit covers
- 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 floorWe remove flooring only as far as the repair needs.
- 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 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 flooringSubfloor solid and clean; we can lay the new floor or coordinate with your flooring installer.
Repair options
Tongue-and-groove plywoodThe usual choice for kitchen subfloors: stiff, holds screws well and tolerates brief wetting better than OSB.
Sister joists and blockingFraming reinforcement that stiffens the floor and backs every seam.
Leveling compound and patchFlattening products for small dips and seams.
OSB panelsCommon in newer construction and fine when kept dry, but its edges swell if it gets wet.
Underlayment layerA thin top layer that adds stiffness or a smoother surface.

Kitchen Subfloor Repair questions from Downers Grove homeowners
Can a subfloor be repaired or does it need replacing?
Loose, squeaky subfloor can be refastened. Rotted, delaminated or swollen panels need to be replaced in the affected area.
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.
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.
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.
