Subfloor problems we fix in Lisle kitchens
Kitchens are where leaks hide: under the dishwasher, behind the fridge water line and below the sink base. Our Lisle carpenters open the floor, trace the moisture to its source, replace what is damaged and reinforce framing where it needs it.
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.
Swollen, mushroomed panel edges
Ridges along panel joints often mean wet OSB. Sanding doesn't fix it; the swollen sections are cut out.
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.
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.
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.
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.
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.
Where we look first
- 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 floorWe remove flooring only as far as the repair needs.
- Cutting out damaged subfloorWe remove the damaged area in a clean rectangle with every edge supported.
- Joist inspection and reinforcementWe check the framing beneath and reinforce it when it is damaged or too flexible.
- 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.
Repair options
Tongue-and-groove plywoodThe usual choice for kitchen subfloors: stiff, holds screws well and tolerates brief wetting better than OSB.
Underlayment layerA thin top layer that adds stiffness or a smoother surface.
OSB panelsCommon in newer construction and fine when kept dry, but its edges swell if it gets wet.
Sister joists and blockingNew lumber fastened alongside damaged or weak joists, plus blocking that supports panel edges.
Construction adhesive and subfloor screwsFastening that grips the joists instead of working loose like nails.

Kitchen Subfloor Repair questions from Lisle 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.
Can a subfloor be repaired or does it need replacing?
Sound wood is secured; damaged wood is replaced. We show you which is which.
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.
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?
Non-structural patches typically don't need one; joist work generally does. We check with the local building department.
What is the Lisle building department phone number?
Permits go through Development Services Department, phone 630-271-4150. When your scope needs one, we prepare the application and schedule the inspections.
Can you do kitchen subfloor repair in a Lisle condo?
