Most houseboats are built with a timber frame and plywood exterior which can let water into the timber and cause rotting. This can often stem from screws or bolts that work loose and allow water ingress. This houseboat had rot in the front brow over the windscreen on the upper deck and also in the lower deck just forward of the duckboard at the back. We cut out the soft areas ensuring that we left a margin around the patch to stay well away from the edge of the rotten section. When we opened up the repair on the lower aft deck we found that the rot had found its way into the aft main timber cross beam so we cut this out and replaced this as well. All repairs were carried out using epoxy not only to saturate and seal the new parts but also for bonding, glassing and filling the new patches. The owner was planning to repaint the entire vessel so only required us to complete the repairs to a primed level.
