In checking a recent job there were several joists that had dry rot and needed replacement, several others showed signs that they may soon follow. Has anyone dealt with a similar situation.Is there an alternate to removing the joists such as a treatment to stop dry rot before it begins?

Skip, You would need an engineer to evaluate whether a joist can be treated, sistered or replaced.
To stop dry rot before it begins, you need to eliminate one of the 4 things dry rot needs to thrive: favorable temperature range (50-100 degrees +or-), Food source, Moisture and oxygen.
Since this is not always possible, you can pretreat and post-treat your lumber with BoraCare. Click on the search button above and type in BoraCare for information previously posted on this subject.
*me,too.. i'm with bill.. except that he counts 4, and i count 3....the food source is the rafter / joist.. so you really can't eliminate that..but if you change one of the other 3, the rot stops..the Bora-Care (and some of their companions .. like Tim-bor) is my treatment of choice also.. in addition to PT where appropriate..skip.. we got a tee-time for Adrian's yet ?
*Don't forget that other condition that is so hard to get away from; a nonsterile enviroment.
*b TVMDCMike, You can remove the wood as a food source by spraying is with BoraCare: that is the whole point of using a borate to fight dry rot and termites.
*good point , bill... sometimes i can't see the forest for the treesbut, i still don't know if skip is gonna get us a tee time..
*b TVMDCMike, We'll play at night with glow-in-the-dark balls
*Bill, Mike thanks, I'm familiar with Tim bor and will recomend it. A home inspector noted rotten joists in a certain area of the house without specifying how many. I am looking at replacing the joists, but the homeowner has a contract on the house and only wants to do what is necessary from the recomendation of the inspector. I originally figured the entire area. Now it is just a matter of ascertaining which joist to replace without missing any. As you know without destroying each joist it is rather hit and miss in deciding which one's to replace. Mike the Highland Links course is rated no.1 in Canada and in the top 100 in the world. Sounds inviting, yes? Skip
*yes it do... if we can get on.... better to play the 3000th rated course than to not get on the 10th rated one...so.. that's a maybe ?
*How do Bora Care and Tim-bor compare with copper based products such as Jasco Termin-8? I've used Termin-8 outside, and its downside seems to be the chemical smell and green stain. Would Bora Care protect as well or better?-- J.S.
*b TVMDCJohn, Jasco may give good protection but the downside, as you said, is the toxicity and smell. I know a contractor who had to remove and rebuild an exterior fence for this reason.BoraCare on the other hand is not toxic to humans nor animals (but is to plants), is effective against termites and is a contact fungicide. Clean-up is with water. After application, it can be stained or painted. For exterior use, it must be protected from moisture since the borate salts are water soluable.
