Squeaky floorboards are one of those things that most people consider a necessary evil of homeownership. Some people think it’s a sign that the entire floor is about to give way, or that a poltergeist is secretly creeping around, or that they really need to hit the gym. In reality, this is a natural deterioration of the floorboards that have dried out after awhile and are now sliding and grinding against each other; there’s also the factor of unstable subflooring. Bare hardwood floors tend to be the main culprits but the squeaks are still perceivable in carpeted areas and tiled areas.
Fixing these common annoyances is an easy enough project for an active home improvement weekender. In any situation, the first thing to do is locate the squeak and mark it with some electrical tape. Now, the toughest situation is when you have no way of getting under a bare hardwood floor and must fix it from above. This will require a drill, breakaway screws, matching screwdriver bit and a depth-control fixture. (O’Berry makes a handy Counter-Snap Kit for this sort of job, which you can usually find for less than ten bucks.) Drill a pilot hole (approximately 3/32 in.-dia) and use the depth-control fixture provided in the kit to drill one of the provided screws into the hole until it snaps off. To conceal the work, fill the hole with wood putty.
Carpeted floors that need to be looked at from above can be similarly fixed. In this case, I highly suggest O’Berry’s Squeek-No-More Kit, which contains everything you’d need for this job, including breakaway screws and a pilot screw for locating joists. If you have a joist locator, it’s a bit easier and quicker. Using either, locate the joist that is in closest proximity to your squeak and mark it. To ensure your carpet doesn’t get damaged, wrap the special breakaway screw with scotch tape when you drive the screw through the fixture. Screw it in and then use the fixture’s side to break off the top of the breakaway screw. All of the work you’ve should be concealed by the carpeting.
The more common and easier task is fixing squeaks from underneath, through a basement. Have a member of your family or a friend walk over the squeaky area while you’re below. Take a thin wooden shim, cover it with carpenter’s glue and tap it into the area between the closest joist and the subfloor. Follow this up with a drywall screw driven through the joist, the shim and into the subfloor at an angle. This is an easy enough fix, but for a more secure fix, get your hands on a hold-down bracket – the most popular one is the Squeak-Ender. This usually consists of a steel mounting plate being held next to the trouble-spot’s closest joist, screwed into the subfloor and then tightened via attached nuts so that the joist and the floor are brought closer together. This should cover most squeaky situations but if you have more questions, feel free to ask.
