Wet rot on joist, how do I repair?

Postby tbear » Wed Mar 17, 2010 1:34 pm

Hi All

Ive just found a bit of wet rot in a floor joist in my bathroom, its affected the one joist to a depth of maybe 30mm for about 10 inches from the wall to just behind the bath. Its dry as a bone now but I think the bath must have overflowed a few times on the carpet which we pulled out when we moved in, maybe 10 months ago. If it wasnt for the need to remove the flooboards ro rewire the kitchen it may never have been spotted as the flooboards look ok.

Question is do I need to cut away the whole of the damged joist back to the good bit and splice a new bit in or do I just need to cut back the top of the joist. Or is this a job that needs a specialist to look at?

Many Thanks.

Simply Build It

If most of the joist is OK you can probably get away with bolting a new joist onto the old one. If your bath is one of those cast iron ones you may have to replace the whole joist.

Wet rot is simply decay of wood with high moisture content. Wet rot occurs when timber decays naturally in high moisture areas. It occurs due to some form of structural decay such as leaking pipes or near the damp wall. To control it we have to identify the source of moisture responsible for the outbreak and rectify it. Heating, ventilation and good building maintenance will prevent fungal decay forming and will form the basis on which it can be controlled. We have to treat the affected area properly so that the problem will not appear again. so act wisely to treat this problem. You can even take the help of some professional which can give you perfect advice. Treat Wet Rot as soon as possible.
