The house that I am about to close on is set on an all wood foundation. It's five years old, and I have concerns about future settling, resale value, and foundation life expectancy. Can anyone give me advice concerning specifics of this type of foundation construction (stuff I should check on or look into). Thanks in advance.

A treated wood foundation is superior to an untreated one. Check the masonry pillars on which the wood beams rest to make sure they have galvanized metal tops on the concrete pillars which tend to discourage moisture and termites. Pressure treated wood is generally good for at least 30 years.

Wunder, Maybe I should clarify what I am talking about. There is no concrete or brick involved in the foundation at all ... just treated lumber. 30 years is not much for a foundation to last ... only about the life of the loan itself.

The most important factor in a treated wood foundation is the drainage system around the base of the house. It should be on several inches..to a foot of gravel/rock with a good sump pump system....battery backup makes sense. Treated wood is going to rot if it gets and stays damp. Keep it dry and it should last. Drainage systems often get roots and heavy rains and shifting earth problems, but if you keep trees and large woody plants away from the foundation, keep a good slope from the foundation to a natural drainage path three or more feet outside the house outline, and maintain your sump system well, you should not have a problem at the end of 30 years or more.

Much depends on your location and soil type. I have 4x4 posts on my deck that are thoroughly rotten on the INSIDE after 14 years. (This is near Raleigh, NC. where we have very acid soil.) Because the vendor says they're rated for 30 years won't make it so. And who wants a house that has a life span of 30 years anyway? You won't be able to resell it. Personally, I would not buy a house that is only supported on wood unless the base under it is solid rock.
I found some information on the subject -- http://www.southernpine.com/permanent.htm

There is a new post under "Basements and attics" dated 7/23. You should read it. It is from Teresa575.

I would run not walk from any wooden foundation system. Any treated wood will get attacked by termites and other insects. The quality of the pressure treating is alwasy suspect. Whenever you buy a house buy one with a full basement where the wood is as far away from the soil (insects and moiture) as possible.
