There should be a flashing between.

Start with having the exterior completely caulked. Call Mike at 866-670-3020 for an estimate.

Not sure, but my thought would be no, due to the moisture involved with rotten logs.

You need to ask an HVAC guy for this one.

I guess it would be acceptable, but probably doesn’t look very good. A properly replaced log should look like the existing logs. Call Ryan at 877-788-5647 for an estimate.

If the exterior has not been caulked or chinked completely, it should be done. Call Mike at 866-670-3020 for an estimate.
