Subfloor problems we fix in Warrenville kitchens
A soft spot in front of the dishwasher or sink usually means water has been reaching the wood under the floor for a while. In Warrenville we find and stop the leak, cut out the damaged subfloor, check the joists and install new panels that are glued and screwed down.
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
Oriented strand board swells at the edges when it gets wet and doesn't shrink back. Those raised seams show through vinyl and plank floors and are replaced.
Soft spot in front of the dishwasher
A slow drip from a dishwasher hose or door seal soaks the floor beneath it without showing on top. We pull the appliance, open the floor and replace the wet section.
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.
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.
Uneven or out-of-level floor
Humps and dips are corrected with planing, shims on the joists or a leveling compound, depending on how far out the floor is.
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 we check and fix
- Finding and stopping the leakNo new subfloor goes in until the water that ruined the old one is stopped.
- 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 flatteningSeams are sanded flush and low spots filled so the finish floor has a flat base.
- Ready for flooringWhen we leave, the base is flat, dry and fastened, whoever installs the flooring on top.

Kitchen Subfloor Repair questions from Warrenville homeowners
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.
Who should I call for subfloor repair?
Call a contractor that does subfloor and framing work, not just flooring. We repair the base and can install the new floor.
Do I need a permit for subfloor repair?
For framing repairs, often yes. For a panel patch, usually no. We confirm before starting.
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.
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.
What is the Warrenville building department phone number?
Permits go through Community Development Department, Building Division, phone 630-393-9050. When your scope needs one, we prepare the application and schedule the inspections.
