How to Stop a Deck from Creaking and Squeaking

Here’s a question from our 6/8/2019 Today’s Homeowner Radio Show.

Dennis from North Carolina says, “About four years ago I had my deck’s floorboards and railings replaced. They were sealed with Sherwin-Williams Deck stain, I believe it was a solid stain. I want to say the original deck board was secured with a pneumatic nailer and the fasteners looked like staples.

“Early fall of last year I had the deck cleaned, all old deck dressing/sealant was removed by a liquid remover; what sealant remained was sanded off. The entire deck was then re-sealed with TWP stain, believe the coloring is California Cedar.

Now when it rains and the deck hasn’t dried, all is well. After the deck has dried after rain, all is well. However, when the floorboards have dried and get walked on, they make popping sounds and squeak like crazy. Seems that all of the floorboards do it. It’s very aggravating and driving me and my wife crazy.

The construction of the deck floorboards’ support is joists on 16-inch centers. Floorboards are attached to each joist using two deck screws. Existing screws measure 0.125”+/- diameter at the shank and are 2.5” long (top of head to thread tip). Floorboards measure 6.5” by 1.125.”

What can I do to eliminate the popping and squeaks? Add a third screw at each joist, replace existing screws with a larger, longer screw, etc.?

We tell Dennis to go along and tighten all the screws in the boards. Try doing just a few boards first to see if that will help before moving on to the entire deck. Another option would be trying longer screws.
