If not, it could twist and bow causing the popping and creaking sound when walked on. Do your boards exceed these spans?ģ) Each board should have 2 fasteners at each support. As a rule of thumb, most grades and species would be fine with: 3/4” thick for 16” span 5/4” thickness for 20” span and 1 1/2” for 3’ span. However, you’d be complaining about the boards being too springy. I doubt the boards could shrink enough to cause this phenomenon.Ģ) If the boards are over stressed (the boards are spanning too far for their thickness), then you could hear a creaking. Then, when stepped on, it would “move” on the fastener. However, shrinkage does not lead to popping and creaking unless it was so wet that it shrunk across grain and lifted it off its supports. So, to solve the “popping and creaking”, we should confirm 1) material (species) used, 2) thickness/span, 3) number of fasteners per support, 4) shape of board, 5) stability (rigidity),ġ) Some species will shrink more than others. I don’t know how they know this.here are some ideas: Some responses have noted that the deck material ie 5/4”, Some refer to it as pressure treated, etc. This may not be feasable now that the deck is built, but I would consider pulling some boards randomly, and trench the water away from under the deck. This controls weeds, mold, and allows for drainage.

It is code is some areas to put down lanscape fabric or 4-6 mil black or clear plastic followed by up to 4' of stone that is 1' down to pea gravel size. The moisture build up could have been avoided if done properly during the deck install. A thick napped roller or sprayer will help with application.

My suggestion would be to replace your existing screws with a size bigger to fill the void around screws/nails etc.I would also check to see if possible, that no fastners have missed any of the joist during installation.Īs far as the the water water sealer goes, you want to put it over every crack and cranny of the deck that you can possibly get to. It appears as though they are are sinking, but actually the wood raises sinse it's not as snug any longer. However, over time the pressure treated wood shrinks around the fastners as it dries and cures. When new pressure treated wood is used for projects, it is fine when it's fresh. I'm honestly not sure what type of wood it is by the way, looks like some treated lumber.

I read another thread and people said it may be caused by too much movement in the deck (could the screws sinking into the wood cause that)? Another suggested remedy was to remove each board one by one and put glue down on the joists, then replace with 3 1/2' deck screws but I want to get some help from DIYers first. Maybe the problem is twofold but I also see some moisture buildup on the underside of the deck when I look up at it from the patio. I noticed also that some of the screws used to fasten the wood to the deck supports are actually going inside the wood (the screw heads seem to be sinking in to the wood). I am not sure if this is what caused it but now after 2 winters, the deck pops and creaks terribly every time we walk on it (of course, maybe not the winter that caused it but last spring it was pretty bad and this spring, even worse). I am learning that this was a mistake and it should have been applied to ALL sides of the deck apparently (according to a DIY friend)? Fall of 2015, we put Thompson's water seal on the top of the deck.
