Subfloor problems we fix in Buffalo Grove kitchens
Kitchens are where leaks hide: under the dishwasher, behind the fridge water line and below the sink base. Our Buffalo Grove carpenters open the floor, trace the moisture to its source, replace what is damaged and reinforce framing where it needs it.
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.
Leak from the refrigerator water line
Slow leaks from fridge lines are hard to see. We pull the fridge, trace the water and repair the floor.
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.
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.
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.
Uneven or out-of-level floor
A floor that rolls under a straightedge needs flattening before new flooring. We choose between leveling the framing and leveling the surface.
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.
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.
- Moisture testingMeter readings across the area tell us where wet wood ends and when it is safe to close the floor.
- 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 flatteningSeams are sanded flush and low spots filled so the finish floor has a flat base.
Common fixes and parts
Construction adhesive and subfloor screwsFastening that grips the joists instead of working loose like nails.
Leveling compound and patchCement-based leveler or patch to fill low spots before the finish floor.
Underlayment layerA thin top layer that adds stiffness or a smoother surface.
Tongue-and-groove plywoodThe usual choice for kitchen subfloors: stiff, holds screws well and tolerates brief wetting better than OSB.
OSB panelsEngineered strand board, used to match an existing OSB floor.

Kitchen Subfloor Repair questions from Buffalo Grove homeowners
Do I need a permit for subfloor repair?
Replacing subfloor panels usually doesn't. Structural work such as sistering or replacing joists often does, and we pull the permit when it's required.
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.
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.
How do you find where the leak is coming from?
By tracing moisture readings and checking each appliance connection, plus a look from the basement when possible.
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.
Does kitchen subfloor repair need a Buffalo Grove building permit, and who files it?
Permits go through Community Development Services, Building & Zoning Services (BS&A Online), phone 847-459-2530. When your scope needs one, we prepare the application and schedule the inspections.
