1. Have an expert come to inspect your wall moisture levels using a moisture meter. This will detect rising damp.
2. Get an inspection carried out for termites by a qualified home builder who is also a licenced timber pest inspector.
3. Once any problem has been identified, take action as soon as possible and arrange for protection. If poor ventilation is identified as been the problem, subfloor fans may need to be installed to allow for correct air flow. If its termites, a chemical barrier may be needed, or a baiting system may be recommended. Termite baits help identify activity of termites on your site, alongside of regular inspections. They do NOT attract termites, they intercept them BEFORE they get a chance to enter your home.
One client I recall had called me to check to see why all her clothes were covered in mold. Upon entering her house I noticed a musty smell. I advised that I cut a floor trap for inspection access to her subfloor. When I got under her house, I noticed 300ml of water! The substructure timbers had decayed extensively from excessive moisture. When I came out from under the house, she wondered why I was soaked in water. I replied, “I didn’t know you had a in-ground pool!
It turned out my client had been living with mold for eight years and didn’t think much of it. In conclusion, we organised a plumber improve drainage, our firm installed a ducted subfloor fan system with a rectified damp-course. About six months later we reinspected the subfloor and it was completely dry.
The skill of inspections and moisture meter readings is a science of interpretation, so experience by the contractor is in these fields are vital. Only choose a home builder and termite inspector who can show proof of their qualifications and experience.
