Squeaky Floor? Fixing It From Above, Because Florida Is Slab

Updated 2026-08-30 · Sources verified 2026-07-20

A squeak is a fastener rubbing, not a structural failure — and in Orlando you almost always fix it from ABOVE, because there is no crawlspace to work from. Permit in Orange County: no permit. Fastening a squeaky floor and repairing floor covering is finish-class repair work. If chasing a squeak uncovers a cut or damaged joist, that repair is structural — and structural work always needs the county permit. The full answer and its source are below, with the code requirements and mistakes that trip up Orlando homeowners.

Key facts before you start

• A squeak is a fastener rubbing, not a structural failure — and in Orlando you almost always fix it from ABOVE, because there is no crawlspace to work from. Census Survey of Construction, South region, single-family homes completed 2025: 4 percent full or partial basement, 8 percent crawl space, 88 percent slab or other. That matters because APA's published repair (Technical Note C468N, April 2002) is written around reaching the joist from underneath, and on a ground-floor slab that access does not exist. The only wood-framed floor in most Orlando houses is a second storey, and getting under it means opening a first-floor ceiling. Assume the from-above repair unless you know otherwise.
• Do not shim the gap with a shingle or a tapered wedge. APA is explicit that the intuitive fix backfires: "Do not use a shingle wedge to fill the gap between the subfloor and the top of the joist. Although the shingle wedge may support the floor at the point of the squeak, it may tend to lift up the floor on both sides of the wedge. This can result in the development of new squeaks." A taper driven into a gap is a lever. Where you DO have access from below, APA's actual fix is a 2- to 3-ft length of lumber or metal angle, predrilled slightly larger than the screw's outside diameter, construction adhesive on the edges that contact floor and joist, the floor pushed down against the joist, then screwed to both — sheet metal screws (more holding power than wood screws of equivalent size), short enough not to penetrate the top surface of the underlayment.
• Punching a popped nail back down buys weeks, not years. APA: "Note that setting a popped nail may only provide temporary relief." The nail already failed once and may not hold the panel against the joist or may work loose again under traffic — which is why APA's own instruction is to install the lumber or angle ALONG WITH setting the nail wherever the joist space is accessible. Setting the nail is the half-measure, not the repair. When you do set one, have someone stand over the joist near the squeak to push the panel down against the framing first.
• The scored repair screw works on a manufacturing detail worth understanding. O'Berry: "The specially scored screw has a variable pitch. It starts at the tip with 8 threads per inch. One inch up it switches to 9 threads per inch. This change draws the wood together." The coarse lower thread bites the joist while the finer upper thread holds the subfloor, and the mismatch pulls the two layers into contact — that is the actual repair, and a regular screw can even hold the gap open. One screw is also not the job: "Normally more than one screw is needed. It is best add additional screws along the joist, spaced approximately 4 inches." A squeak is a length of loose panel, not a point.
• Finding the joist from above, and the three surface traps. O'Berry: joists "almost always parallel the narrow dimension of the house"; start about 9 in. from a wall that runs parallel to them, or beside a floor vent, which "is always between two joists"; joists are normally 16 in. on center, so one hit gives you the rest. CARPET: on berber or any loop pile, tape over the screw tip and threads before driving or the thread grabs a continuous loop and pulls a strand — cut pile does not need it. HARDWOOD: the joist-finding screw does not work, because each plank carries its own nails, so drive into "the plank that is visibly moving or where the noise is coming from, not necessarily into the joist"; the head snaps 3/8 in. below the surface, so fill with matching wood filler. STAIRS: the squeak is the nails holding tread to stringer or riser, so set the fixture over that connection, not out on the tread.
• Rule out the two causes a screw will not fix, then know when to stop. A squeak right along an interior partition wall is often the wall's bottom plate nailed to the subfloor instead of the joists, the panel rubbing the nail shank as it deflects — APA's fix is to clinch those nails, screw up through the subfloor into the plate, or add diagonal blocking under the partition. A squeak beside a floor register can be the floor bearing directly on the metal duct where the hole is a snug fit — APA: "Either provide clearance or stuff fiberglass insulation between the ductwork and the floor element on which it is rubbing." And if correctly installed screws do not silence it, stop: O'Berry treats a surviving squeak as evidence of something else — "floor damage due to misapplication of the sub floor, water damage, structural damage, mechanical damage and other causes" — which "should be referred to a carpenter or floor professional to prevent further damage." In Florida water damage is the one to take seriously; a persistent squeak over a soft spot is a different problem, and the termite and wood-rot guide covers how rot gets identified and reported here.
