Subfloor problems we fix in Glen Ellyn kitchens
The subfloor is the layer of plywood or boards that every kitchen floor depends on. We repair it in Glen Ellyn homes when it has gone spongy, rotted, squeaky or uneven, and we leave it flat and dry for the finished floor.
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.
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.
Uneven or out-of-level floor
We measure the floor for flatness and fix high and low spots so the new finish lays flat.
Cracked tile or separating plank floor
Flooring repairs don't hold over a moving subfloor. We correct the base before any new finish goes back.
Floor too thin for tile
Planning porcelain on a floor built for sheet vinyl? We check the thickness and stiffness and build it up as needed.
Bouncy or sagging floor
A floor that flexes when someone walks through may have undersized, damaged or notched joists. We check the framing and may sister new lumber alongside.
Damage at a seam from a past repair
Earlier patches that weren't supported on joists or blocking tend to sink and crack the floor. We redo them with proper support at every edge.
What we check and fix
- 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.
- Moisture testingA moisture meter shows how far the wet wood extends and whether the framing is dry enough to close.
- 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 flooringThe repaired area is left ready for tile, plank or wood, and appliances go back when the floor is finished.

Kitchen Subfloor Repair questions from Glen Ellyn homeowners
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.
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.
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.
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 long does subfloor repair take?
A dishwasher-area patch is often done in a day; larger repairs with joist work or drying time take longer.

Yes. Our crews work across Glen Ellyn — ZIP 60137 — and nearby Wheaton, Lombard, Glendale Heights.
