View Full Version : Treating cedar fence posts

Any suggestions on what to use to treat a cedar fence post that is below ground? I pulled a couple of cedar posts at my place that have only been in the ground 4 or 5 years and I was amazed at how much wood had rotted away. The soil around the yard is very well drained, high sand content. I have a fence project coming up in a couple of weeks and the homeowners are fairly particular. I do not want a call back from them in a few years because the posts are starting to rot away. I was thinking something along the lines of Cuprinol, but to be honest, I'm not sure they even make that anymore?

Are you certain that your posts were cedar? 4-5 years is far too short a span for posts in the ground (assuming a base diameter greater than 4").

Yup, it was a 12' cedar pole with about a 6" girth. The section that was underground, I'd say close to 1" had rotted away in places. It had actually been in the ground 6 years - or just under.

The soft wood in cedar will rot away in a few years. The rest will last a long, long time.

Loosing 1" on a 12" post doesn't worry me. Once the lighter colored wood is gone, the darker stuff will still be there.

pole was 12' long, diameter of post was only 6"

Hey, I'm not even sure about that: diameter is distance across, girth is circumference which would make the post plus or minus 4" diameter.

A momentary laps in judgment. Posts are 6" in diameter, not girth or circumference.

How many years could I expect to get out of 8-10" diameter raw Eastern Red Cedar posts set 2'-3' in ground with concrete?

I like to put gravel in the bottom of the hole and set the post on that and back fill. Gives the water a place to go, Keeps the wood drier. The way I look at it, you take these 100 year old barn's that have never been painted, would gets wet, wood dries out. no problem.dry wood doesn't rot, it's the wet wood that rots. Ever go in a crawl space and see a lot of "Dry rot"? ever notice how damp it is down there? Makes you wonder why they call it "Dry Rot".... Anyway just my opinion, the post doesn't sit in a pool of water that way, the water goes down to the the gravel sump.
