Noisy floors are usually loose, not broken. Re-securing the panels to the framing quiets them.

Subfloor problems we fix in Arlington Heights kitchens
Kitchens are where leaks hide: under the dishwasher, behind the fridge water line and below the sink base. Our Arlington Heights carpenters open the floor, trace the moisture to its source, replace what is damaged and reinforce framing where it needs it.
Musty smell or stains in the basement ceiling
A damp smell near the kitchen floor or stains seen from the basement are worth investigating before the floor softens.
Swollen, mushroomed panel edges
Raised lines in a floor that follow a grid usually trace swollen subfloor seams. We replace the damaged panels.
Floor too thin for tile
Thin or single-layer subfloors can crack tile and grout. An added layer and solid fastening make the floor tile-ready.
Damage at a seam from a past repair
A patch that dips at its edge was likely cut between joists without blocking. We open it and support it correctly.
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.
Rot found during a remodel
When tear-out reveals rot, it has to be replaced, not covered. We repair it so the remodel can continue on a solid base.
Soft spot in front of the dishwasher
That spongy patch near the dishwasher is one of the most common subfloor repairs we do. The leak gets fixed first, then the damaged panel comes out.
What the repair visit covers
- 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.
- Moisture testingWe measure the wood moisture to set the repair boundary and confirm it is dry.
- Cutting out damaged subfloorWe remove the damaged area in a clean rectangle with every edge supported.
- 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.
Repair options

Kitchen Subfloor Repair questions from Arlington Heights 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.
Why is the floor soft by my dishwasher?
Almost always water. A leaking hose, drain connection or door seal soaks the subfloor until it softens. The leak has to be fixed along with the floor.
Can you replace just a section of subfloor?
Usually, yes. Partial replacement is normal as long as the edges are properly supported.
What affects the cost of subfloor repair?
How much area is damaged, whether joists need work, removing and replacing the finish floor and moving cabinets or appliances. We give a written, itemized estimate after the visit.
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.
Arlington Heights building permit for kitchen subfloor repair: where do I apply?
Permits go through Building & Life Safety Department, phone (847) 368-5560. When your scope needs one, we prepare the application and schedule the inspections.
Can you do kitchen subfloor repair in an Arlington Heights condo?
Associations usually set rules for work hours, elevators, deliveries and insurance, and many require approval for plumbing, electrical or structural changes. We provide the certificate of insurance and follow the building's rules.
Do I need a permit for kitchen subfloor repair in Arlington Heights?
