Hello, on the front of my home are three old barn beams extending from the structure. They were used by the original owners/builders in the construction of the home in 2007 to add character. My question is in two parts. The first question is "what is the best preservation method for these beams?" I've been told everything from just leaving them as-is to encapsulating them in marine grade epoxy. I really like the look but don't know if I should be maintaining them is some way. The second question involves the water staining on the boards underneath the over hang. I believe the best way to address this would be to sand the boards down and then re-stain and finish with a clear sealant. Any assistance would be very much appreciated.
