Repair

  • log walls should be cleaned once a year or as required to remove dirt, cobwebs and other organic matter. Use a soft bristle brush and water from a garden hose. If you want to use a cleaning product, ask a log house company for a recommended product. No not use chlorine bleaches or detergents that may leave a film behind. Avoid high-pressure water blasting, which can damage the log surface and sealants or caulking
  • many log home manufacturers use and/or recommend a protective oil or stain. How often this will need to be reapplied depends on the preparation of the logs, the level of exposure the logs get and the product being used but can typically range from every 2–5 years. The logs should be cleaned and allowed to dry completely before the oil or stain is applied. Follow the preparation and application recommendations of the coating product manufacturer
  • there is a Log Building Association of New Zealand that has some information on its website
