Need to replace the decking on my back yard deck.

[flamin lib]

Originally used pressure treated lumber and it lasted 40 years but has at least succumbed to rot in places. The substructure is sound so just replacing the surface.

Any opinions on pressure treated pine vs regular construction pine with regular staining?

1. If the deck is attached to your house...

Absolutely pressure treated because the treatment makes it highly insect resistant. Mr. Had a design build landscape firm for forty years.

2. Get the treated.

The untreated pine will deteriorate much faster. Even then you should apply a water sealer to the deck once installed.

On edit: You can apply the sealer before but once you nail it down you would need to reapply because the nails will break through the sealant.

11. I totally agree with cedar!!

My daughter and I just ripped off 25-year old pressure treated boards from our deck and replaced it with cedar.

I had been going back and forth trying to decide whether to use composite decking, but in the end chose cedar. It looks good, smells good, is rot-resistant and a whole lot easier to work with than PT.

The price was just about the same as composite and was very easy to install using that CAMO tool (no exposed screws).

After we stained and sealed it, it looks completely gorgeous!!!

(I do have a small complaint --- after a rain, the water just sits on top of the boards --- so we had to get a large sqeegee to push off the water).

4. Get the treated.

We did our deck in regular pine and stained it every year. It had to be replaced in less than 10 years. It had not completely rotted but had bad areas with huge splinters and many of the boards had warped.

5. Did ours in TREX in 2000 and its still perfect today

Spent the extra up front and glad I did. Never have had to paint or sand. The addition of stainless screws eliminated any possibility of rust also.

Would not hesitate to do it again, but probably never will in my lifetime. Could attach a photo if I knew how.

6. I built a deck in 1989....replaced it in 2016 because

I wanted a new look. It was still in good condition when I tore it out. In fact, I used many of the 2x6s for other projects.
For the new deck, I used the very best "pressure treated" lumber I could purchase at the big box store. It is already rotting(and yes, I used the best deck sealant I could buy). Good luck with your search, but just be aware that nothing last like it used to do.

7. The old PT lumber was a different product.

Got pulled off the market cause it had arsenic in it. The new stuff is only good for half the life of the old stuff.

8. Well, I'm glad it was pulled because of the arsenic....

but the "shelf" life of the new stuff sucks big ones.

9. Go with TREX

I'll echo the poster below. Well worth it.

10. 40 years is a remarkable time for a deck to last

At least here in Colorado. The sun is our greatest problem. A lot depends on your climate and humidity.
I would be inclined to replace with the same material that lasted 40 years and let the next owner deal with it when that time comes.

12. Suggestion

There are a number of ways you can choose to replace your deck. I would suggest you to go with the composite decking as it will give you desired flexibility. Also, if you want your backyard to look more elegant get a new furniture from any of the genuine furniture providers and make sure that you choose the best design furniture for your backyard. Last month, my cousin did the same by purchased a new design set of furniture from the official source at an affordable price and now his yard looks really amazing and comfortable too.
