Should I be concerned? It's good to be concerned, as many decks are poorly built. Fortunately, most 'cracking' of support columns doesn't affect the integrity at all. This type of cracking is called 'checking' and happens as the wood slowly dries out. Code typically is accommodating of this...hence the 6x6 (as opposed to a 4x4). If you visit an old ...

There may be some options on how to handle this situation but you have left out some pretty important information. Missing is how high the existing 4x6 supports are already. It the posts are only 6 inches high then it would be pretty hard to add 30 inches on top of them. On the other hand if they are 4 feet high then the possibilities increase. Given ...

You can always test it by see if the water beads up or soaks in. I'm in Arkansas. My deck and front porch were built in March. They both get good sun. I'm waiting until August to do mine. Plenty of good hot sun to dry them out. The pine lumber came from Lowe's.

Rain really will not hurt unless the deck is wet when you seal it. If wet when sealed depending on the type of sealer it may be ok (water based) or with oil based it will not adhere as well.

Scrape, sand, prime and then paint with exterior grade products. Longevity of the paint will also be based on the moisture content of the wood at the time you painted it. A handy 'mini-Ligno' moisture meter is used to determine if the wood is dry enough to hold primer and paint. Consult with the paint manufacturer for moisture content recommendations. ...

Hit them with a hammer to hear if they are solid. If the are rotting they will sound flat or hollow, if they are solid you can hear it. You could also power wash them to get a better look at their condition. From here they look fine. But then looks can be deceiving. Good luck!

Pt lumber is pressure treated, meaning the use 400 psi to make sure the chemical stays in the wood, most stains and paint won't stick until the pores of the wood come open which can take years .

The real answer is to replace the post. But if you need a quick fix, perhaps a couple of braces would work. I think that a wood post anchor might work too, if you can slip it over or under the post (maybe it's too late for that).
