New Front porch post Repair Question
 
Just discovered that I have a front stoop with a roof overhang that is supported by a turned post and it's rotted at the bottom.
The previous owners user some sort of filler to hide it, but it's pretty bad. The post looks like it's sitting on a piece of 2x 8 which is not as bad as the bottom of the post itself. To make things more difficult, the front stop is concrete with brick laminated over the top and was added after the post. My question is what to do at the bottom to mount the post. I will pull up the brick, but want to replace them. Should I go with a treated 2x8 again, or should I make a concrete step the height of the bricks to mount the post to. The 2x6 actually sits under the bricks and were cut to go over the top of them.
Thanks

Post a picture.
Wood post should not be in direct contact with the deck, that why yours rotted out.
The best way would be to just replace the wooden one with a vinyl one. It will have an aluminum beam in the middle and can easly hold up the roof.

Attached is a photo. You see where the bricks were cut to go over the 2x8. I found replacement posts at Lowes and a plastic mounting spacer for it to sit on. I'm worried because that would be below the to surface of the bricks. Would that be a problem? Should I create a concrete pad to match the surface of the bricks, then use the spacer?

Thanks

Can you back up and take a picture of that whole deck and include the roof in the moring when it's light out?
There's no way I can see there ever should have been a 2 X of any size should have been used as a porch post.
Depending on the roof load it had to be a minimum of a 4 X 4, 4 X 6 or 6 X 6.

I'll attach a picture this afternoon. I think I've caused some confusion. The post is a 5x5 at the base. It's turned in the middle to a spindle shape. It is sitting on what looks like a 2x8 which is sitting on my cement porch. The 2x8 doesn't look as bad rot wise as the post. So what I'm trying to ask is when I replace the post should I put it on top of a new 2x pressure treated or rot resistant board, mount it directly to the cement with the plastic spacer, or create a concrete pad level with the bricks?
Thanks

have you checked to see if you are getting a leak from above causing the rot and damage, that is what I find lots of time if a post like that is rotting especially if there is tile on the porch above, yikes...

First off there shouldnt be any 2x8 on the flat under any weight bearing post. Second it should not be in direct contact with concrete at the bottom, especially buried under 3 inches of pavers.

Your really need that post to sit on a post base to keep the post from being in contact with the slab.

Then you could set the pato blocks around the base block, and to cover up the rest of the bracket that shows you could wrap it with 1 X 6 vinyl limber and top it off with vinyl base cap moulding to cover the gap and to give it a nice finished look that never going to rot again.

I'll definitely look for the hardware. Sorry to keep asking querstions, but I don't want to do this twice. Do you see any concerns if I use the mounting bracket and the bottom of the post falls below the top of the pavers. I'm worried about moisture and water pooling still. I'm thinking of building a concrete pad then the bracket so that the actual bottom of the post falls above the pavers so no water would pool around it. Thanks for your help so far.

A thin pored pad is just going to crack and will not stick to the old concrete.
Are those pavers just dry sat in place? I can not see any grout or morter?

It not going to harm the post block to get wet.

The pavers were glued to the concrete slab with landscaping paver cement and sand in the joints, not mortar. I'm confused whaen you mention post block - what is that? I wasn't going to use a paver under the post, I didn't think that was a good idea. I'm thinking I would buy a bracket mount it to the concrete. that would leave the bottom of the post about 1" above the cement stoop, and probably 2" below the surface of the pavers. I'd then wrap the bottom with a PVC type molding to cover the bracket and help wick water away from the post - am I on the right track?
Thanks

Yes, sounds right.
