rotted wood at bottom of porch support


The porch at the front of the house is supported by vertical wood posts: at the bottom of one of the posts the wood has rotted.(see photo). I removed the front piece of rotted wood. I also removed a square metal platform from the inside with spikes on the top (see to the right of the post sitting on top of a pice of paper). The platform sits below the vertical post on top of the concrete itside and is supposed to support the wood above.

My plan is to repair the support and then to finish to make it look good. I am thinking to use a new peice of wood inside and also some resin putty.

I hope the presentation is clear. I welcome suggestions on repairing this.

You need to support what ever that is holding up. Remove the post. Fix the concrete attachment point. Install new post and trim out to match old one.

Putty will not hold up the porch roof. The metal bracket was there to keep the post off of the concrete. The cheap pine trim boards around the post trapped water causing the rot.

If it was mine I would just replace the whole thing with a vinyl post. No more rot or painting ever.

rotted wood at bottom of porch support


Yes: The square metal piece like a platform shown in the previous post was not set in the concrete. It sat on top of the concrete and the spikes on top of the metal went into the wood above. I am puzzled by how this was used to set the post in positon at he bottom in the first place. I have never seen one put up. Let me show the configuration of the post and the porch.

There is no sign of the porch sagging...none at all. I am wondering how one goes about removing the post since it is connected to the wood above.

Is this a big job? how mcuh would it cost to get it done

It's removed with a bottle jack and a 4 X 4, only need to lift a tiny amount to take the weight off the post.
Hard to tell from that picture but it looks like that trim is nailed to the post and the paint lines will need to be cut and the boards pryed out enough to cut the nails off with a sawsall.
Going to have to make some local calls if you want a price.
It's a really simple 101 job.

the vertical "posts" are made of planks of wood at right angles to each other. I think the interior is hollow. I am thinking to leave the vetical post in place.

I am thinking the bottom part (where the rotted wood is) which is broader than the post can be removed, but first I have to support the weihgt at that point with a vertical piece of wood up underneath the porch.

Then rebuild the bottom part with pieces of wood?


Howe does that sound.

To do it right it would not be hollow. It would be a 4 X 4 or 6 X 6 that's been wrapped with those 1 X's.
What you have there is a real mess. Looks like someone used a stick to apply the caulking.
If your a fan of peeling paint and rotting wood then just patch it.
Want to do this once and be done with it replace it with all vinyl.

Thank you for the schematic: I never knew a roof-jack existed. I am thnking to repair the bottom section, since I think it will ber easier than removing the entire post.

I haven't tried this but a friend once suggested using a 4x4 post on an adjustable pier block to raise a roof.

BEN: You are correct. I have investigated and I found that it is purely decorative. It is indeed hollow and made of planks of wood. I have never seen a hollow post before. A neighbor of mine fixxd it for me. He cut off above all of the rotten wood and replaced the part at the bottom. He used a nail gun driven by air pressure and a chop saw to cut the pieces of wood to size. He even had pieces of wood at hand and he used my small Table saw as well. He had all the wood you need and the trim, caulk e.t.c. He has done this kind of job before. I have just primed it and I will finish it with semigloss exterior,


When is a "post" not a post?........It is when you have an arrangement like I have. It is not engineered to support the porch.

Many thanks to those who have taken time out to write in.

Angus

Wood in direct contact with the concrete is just going to rot out again.
He should have at least drill drain holes at the very bottom.
It's done by marking out a piece long enough to make two pieces, drill a hole in the middle of the cut line then make the cut, Now you have 1/2 a hole for drainage.
That whole thing should have been primed and painted two coats before assembly.
