We need to replace our redwood fences. One neighbor claims that untreated
redwood is more rot reistant than treated wood.
Can anyone tell me what fence post is more resistant to rot and insects:
pressure treated posts or untreated redwood?
Is the brown pressure treated wood better than the green treated wood?
Is there some website that you can direct me to that shows this information.
thanks in advance
buffalo ny: this may save you some money. this may depend on your
climate, soil moisture, and drainage travel. easiest answer sometimes
comes from the permit office or local fence company. careful of the
type of pressure treating it may be limited in your area regarding
kids and pets. you may need to check your survey for placement, and
your town for limits and right-of-ways. regardless of how long your
fence has been around, fences are often excluded from front yards,
intersections, and even some neighborhoods by zoning. since life and
cost per year are probably concerns, you'll want to read more at:
I assume by brown you mean creosote treated. I've never seen fence
material treated with that. Plus it's very toxic for yard use.
(Creosote is now a restricted use pesticide). That leaves the green
(ACQ) treated wood, redwood, or cypress.
If you live in the NW, redwood may be an option but the last time I
inquired at my local lumber yards I was told "no one stocks it
anymore, and if ordered be prepared to pay VERY high prices."
If it were me, I'd use treated 4x4's and cypress boards/panels.
Answers to some of your questions depend, in part, upon where the
fence posts are locate.
Are the in southern Louisiana, Mississippi or Alabama, Florida?
Are the posts in Alaska? High desert country in the Great Basin?
All different sets of bugs, different precipitation and ground water issues,
different teperrature cycles and different freeze / thaw issues
regarding ground water.
Also, of course different soil types with different watrer retention issues.
All of these have a bearing on wood post longevity.
Can you tell us more about the climate, soil type and geographical
Universaly, the plastic / ? PVC ? posts will hold up well, but it
like that will fit in with your CC&Rs.
Just had my fence built. Heartwood redwood fence with the brown treated pos
t and a six inch 2x6 kicker of treated wood. And there are some corrosive
material in the treated wood. So the framing was done with coated screws. M
ake sure they mix your concrete and not just dump and add water at hole. An
d last, make sure the concrete is mounded around post, not to hold water.
Hope this helps, DK , CA
