Among the myriad problems you can and will have around the house, a creaky wood deck is among the most annoying yet simple to repair. A creaky deck is not a safety issue but it can exponentially decrease your enjoyment. High-pitched squeaks are cause by boards rubbing joists beneath them. Fortunately, stopping the noise is a quick and easy fix that will leave you wondering what took you so long to do it.
Walk along the deck to identify the trouble spots. Listen for squeaks and feel for movement.
Drive several screws into the decking and joists where you hear the squeaks. Test for squeaks by jumping on the spot.
Add additional screws along the offending joist if the squeaking continues.
