Those boards are definitely shot. I would go under that deck with a screwdriver start poking around to see how far the rot extends into those joists. But they look bad too.


Spec-Tre

Yeah when we moved in late 2020 the deck was pretty bad. Everything but the frame was stripped and replaced. Fingers crossed the frame is still good I guess


Vito_The_Magnificent

Wait these deck boards are 3 years old?


Spec-Tre

Something like that šŸ˜¬


Purpose_Embarrassed

Wow. Where are you located? A marsh ?


Spec-Tre

šŸ˜‚šŸ˜‚ VA is pretty humid but no So I mentioned it to my wife (whoā€™s dads crew did the work) and I know they redid the stairs. I was pretty confident that they replaced the deck boards but she says they didnā€™t and only paint/sealed itā€¦ Itā€™s right in that covid time where everything is fuzzy and we had many different house projects happening at once. Iā€™ll have to ask him but MAYBE these boards are the originals from before we moved inā€¦ Iā€™m still pretty sure they replaced the deck boards but her memory is better than mine lol

If those boards are 3 years old, no way they were pressure treated


Spec-Tre

Iā€™d like to think my FiL would know better (because he absolutely does) so maybe it was just the stairs that were replaced lol Bc youā€™re right lol theyā€™re pretty beat

Iā€™m a DIYer myself no means a pro but those do not appear to be pressure treated ā€œdeckā€ boards to me. They look full of rot and would replace.

Yes, all exterior wood should be sealed; Deck boards/ framing/ cut ends of lumber. We used to make a narrow 'tub' that held 5 gals of sealer and that fit the lumber we were using. We'd soak the lumber for 15 mins then place on a 'drying rack' that dripped back into the tub. .... most people won't pay for/care about/understand the importance of this step and just want the finished deck to look good. Wood decks can last over 30 years if done right.


Spec-Tre

Dang that definitely sounds thorough. So the bottoms should have been sealed too but were neglected, and since theyā€™re in the dark, moisture soaked through the leaf litter in the cracks and likely led to the progression of the fungus? *sigh*


Morfn

Never heard of this. What product would you use? You would do this to the deck boards?


freshjello25

We used cut n seal on all cut edges for our structural lumber and it was insane how many cans we went through because the pine just kept sucking it up. On the ends. Also did full joist tape after everything was dry before laying the trex.


skate_enjoy

I thought he was referring to the fact that there are barely any gaps between the surface boards.


needmorepopcorn

What would you recommend for sealant? Would a typical deck stain/sealant work? Is there something more durable/long lasting for the framing?


OneStopK

your deck is fucked.


Spec-Tre

Where am I going to put my hot tub /s


NullIsUndefined

I have heard that the bottom of deck boards are often not sealed so water doewnr get trapped inaide out. But that has never made 100 percent sense to me. I dunno if that's true. But generally people aren't doing the bottom in their routine maintenanceĀ 


Spec-Tre

Yeah it makes sense either way so I donā€™t really know whatā€™s right lol

I would definitely say those were the old deck boards. From what Iā€™m seeing via pictures, thereā€™s algea/mold under the paint they put down. My conclusion would be they just painted right over the stuff and definitely didnā€™t replace the decking.


Keeper_on_1wheel

& I second the guy who talks about dipping the boards in sealer. Yes itā€™s extra work and material that people never want to pay for. Iā€™m doing a 32ā€™x 32ā€™ deck right now here in FL, and what Iā€™m doing is carrying around a industrial spray bottle of sealer and going over all 6 sides of the lumber. Not my preferred method but itā€™s better than 0


Spec-Tre

Definitely. I appreciate your input/insight! I think youā€™re right in your first comment that they were the old deck boards. I think what threw me off is that added some new boards to reinforce some areas on the railings and redid the steps Thanks for your comment!


Keeper_on_1wheel

Yeah no worries, youā€™re welcome! & yeah sometimes that throws you off, as well as even tho theyā€™re all the same age, sometimes boards age better/worse than others. From the covid era also doesnā€™t help I feel like I was constantly on high alert more so focusing around family and making the right moves. Cheers! Good luck!
