Replacing tongue & groove porch flooring...where can I find wider boards?

I have a brick porch on my house that has old tongue & groove flooring on it. The old flooring was painted, the paint is peeling and the boards on the end are rotten (rain tends to blow in the end of the porch) and a previous owner covered it with indoor/outdoor carpeting that is now in really rough shape, so I want to pitch the carpet and replace the floor.

Porch measures 22' long x 7'4" wide, not sure why it is such an oddball width, and the existing boards are 3 1/4" wide. I found pressure treated 3 1/4" wide tongue & groove at Menards, and it is the only stuff I've been able to find that is treated (which is what I want to use). I found results on google for wider boards at Lowe's, etc but all of it says it is not available.

I calculated that I would need something like 85 boards to redo the whole porch and I'm not liking the thought of having to cut down 85 boards to 7'4" long. Do I have any other options? I know composite decking is out there but I have a feeling that would cost a lot more than I want to invest in doing this porch (as it is I would have $500 in the pressure treated wood).

Right now lumber prices are extremely high. I would at least price synthetic or wait 6-12 months to see if lumber prices come back down.

Regardless of price I would always recommend composite, you need to think long term, no sanding, staining, maintenance.

I just checked the cheapest that HD had and for your 286 sq ft it was around $300!

You would not put composite decking on a porch that is not framed with treated lumber. Tongue and groove planks at least will shed most water. (Assuming it's an open porch)

Is your wall framing sitting on top of the flooring? Or does this porch floor never get wet?

Install full length and cut with a circular saw using a straight edge guide or cut to a chalk line.

Sure you can! Not exactly sure how to fasten it but has to be better than wood!

Composite

Trex has a composite 3.25 tongue and groove board. It would cost you $2500 to cover the deck. If you go with the PT 3.25, paint will always be an issue but, at least it won't rot. Sometimes expansion and contraction can be a problem with the PT lumber. Make sure you use the correct fasteners. Instead of paint, you could stain it. Less of a problem.

So as I said this porch is brick meaning it has the ~2' high brick walls around the sides with an opening for the steps. Any installed boards would have to be cut to length before installation. And yes the porch floor frequently gets wet due to rain/snow blowing in the sides of the porch.

I don't know what kind of framing is under the floor currently. I do know I really don't want to spend $2500 to redo the porch. Marq1 what did you find at Home Depot? When I looked on their site they didn't list any pressure treated T&G. I found 6" wide boards on google but as I said, when I go look at them they say they are unavailable.

If I go the pressure treated route I would probably not paint, staining would be most likely.

Are there any scuppers (drainage openings) in the brick for water to drain through? Or does water running forward just leak through to the crawlspace below the porch?

No drain openings so yeah, currently it just soaks into the carpet but without the carpet it just sits on the wood. Probably why the boards on the end are rotted.

If you can't find treated, this would be the next best thing: https://www.homedepot.com/p/1-in-x-4...5170/100019409

And it could be painted. Those old porches are typically battleship grey, oil floor enamel. It's pretty bulletproof provided you keep it maintained. 50 pc @ 12' would be about enough provided there isn't too much waste. ($500)

You would put the beaded side down. Complaining about all the cutting is nonsense, because you will obviously have to cut every piece to fit. That's just how it works.

You will avoid waste by cutting the first one to fit, then start the next row with the piece left over from the previous row. And it will need to land on a joist too, so before you nail it down you will need to cut it to hit the center of a joist. Then measure the next one, cut it to finish the 2nd row, use the remaining scrap to start the 3rd row, and so on.

This is why DIY'ers accumulate tools. A cheap miter saw, air compressor, hose, and a crown stapler or nail gun would make this go fast.

Here is a low cost composite from HD. 1x6x16', you would need 11 boards for your 22' long deck, so that's 11 boards at $26, around $300!

ghunt81,

11 boards would cover an area roughly 5.5 x 16... about half of your porch.

IDK, math must be different here in MI.

Deck is 22' x 7'-4" = 161.26 sq ft

Boards are 5.5" x 16' = 7.33 sq ft

161.26/7.33 = 22.05 boards

Assuming a bit of scrap then lets go with 23 boards

I have no idea how you quote on this board, but-

"If you can't find treated, this would be the next best thing: https://www.homedepot.com/p/1-in-x-4...5170/100019409 "

Closest I can even get this stuff is in Uniontown, 2 hours away....not sure if I want to drive that far for something that isn't even treated.

Well, I may have to pull up a couple boards and see what the framing underneath looks like.
