A squeaky floor can be a constant source of frustration for homeowners, especially when trying to move quietly through the house at night.
Understanding the root cause of floor squeaks helps determine the most effective repair method – usually it’s either loose floorboards or joists rubbing against each other.
This guide covers proven DIY solutions to fix squeaky floors, whether you have hardwood, laminate, or carpeted flooring.
Common Causes of Squeaky Floors
- Loose nails or fasteners
- Gaps between subfloor and joists
- Seasonal wood expansion/contraction
- Worn out joist hangers
- Improper installation
Tools Needed for Floor Squeak Repair
- Drill/driver
- Wood screws

Quick Fixes for Hardwood Floors
Sprinkle talcum powder, powdered graphite, or dry lubricant between the floorboards where they squeak.
Drive 1-1/4 inch trim screws through the boards into the joists, countersinking them slightly below the surface.
Use a squeak-relief bracket system designed specifically for hardwood floors.
Fixing Squeaks Under Carpet
Locate the floor joists using a stud finder and mark their position on the carpet with painter’s tape.
Use a specialized squeak-repair kit with breakaway screws that go through the carpet.
Drive the screws through the carpet, pad, and subfloor into the joist below.
Repairs from Below (Basement/Crawl Space)
- Install wood shims between the joist and subfloor

FAQs
- What causes floor squeaking?
Floor squeaks occur when wood floorboards or subfloor materials rub against nails, other wood, or joists due to loose connections or wood shrinkage. - Can I fix squeaky floors without removing carpet?
Yes, you can use a stud finder to locate joists and insert special carpet-friendly screws designed to secure the subfloor through the carpet. - How effective is talcum powder for fixing squeaky floors?
Talcum powder is a temporary solution that can reduce squeaking by reducing friction between boards, but it needs frequent reapplication and isn’t a permanent fix. - Do squeaky floors indicate structural damage?
Not necessarily. While squeaks are often harmless and caused by normal wood movement, persistent squeaking in multiple areas should be inspected by a professional. - Can humidity affect floor squeaking?
Yes, changes in humidity cause wood to expand and contract, which can create or worsen floor squeaks by loosening connections between boards and joists. - What tools do I need to fix squeaky hardwood floors?
Basic tools include a drill, screws, shims, a stud finder, a hammer, and finish nails. Specialized tools like counter-snap screws may be needed for specific fixes. - How do I fix squeaky floors from below in my basement?
From below, you can install wood shims between the joists and subfloor, or use bridging blocks between floor joists to reduce movement. - Will WD-40 permanently fix squeaky floors?
No, while WD-40 might temporarily reduce squeaking by lubricating the wood, it’s not a permanent solution and could potentially damage floor finishes or attract dirt. - How much does professional squeaky floor repair cost?
Professional floor squeak repair typically costs between $200-$1000, depending on the floor area, accessibility, and repair method needed. - Can squeaky floors be fixed in winter?
Yes, but it’s best to wait until the wood has fully contracted during the heating season to ensure repairs are effective when the wood expands again.
