The house was built with green logs and will probably leek sap for many years.

wash them with 4-5 gallons of warm water and 1 cup TSP with 1 cup bleach. Rinse with clean rag and clear,warmwater.

I would not ”oil” the logs. You should use a stain like Life Line Light Honey withacoat of Acrylic Satin or Gloss clear on top so that the dust will not stick to it and you can wipe the logs down every year.

Wash your logs with the warm water TSP and bleach mixture then rinse with clean water. I cannot say how to prevent it since I’m not sure of the source of moisture. You should get a de-humidifier going in the house when it is humid.

Make a flat spot on the log surface. use a chissel and sander to fade the flat area out. use extension box if neccessary to attach the fixture to.

You will have to apply caulk around the knots on the exterior. We normally do not like to do this , but it sounds like you have no choice. Just be sure to inspect them twice a year looking for dry and cracking of the caulk.

Wash it with a soft brush and a mixture of 1 cup bleach and 1 cup TSP to 4-5 gallons of warm water. You then can ”MIST” the house to rinse it with you power washer. True power washing is not a good thing for log homes.

Those homes are usually built with foundation of pillers. Stone/tree stump or concrete. Maybe the stump or pillar has settled. Tearing out the floor might be the only solution and re installing a footing. A local builder should help with this.

Get some de-humidifiers. Even rent some commercial kind if possble. You must have a wet foundation area and need tile drains around the perimeter. Maybe even plastic on top of sand if you have just a crawl space. Hire a local home inspector to give professional advice and direction.
