I've got a balcony off my master bedroom that has serious dry rot in the deck planks. Doesn't look like the 2x10 support beams are affected, just the 2x4's of the balcony deck itself. SoCal location, lots of sun in the summer, but because of the location of the house, the balcony gets no direct sunlight during winter months. I've looked into the engineered wood product, but as we can see the underside from the patio, this product isn't a real option. All the products I've looked at don't have a 'finished' underside. Railings, deck, etc. are all painted. Thinking cedar would be best, but $$$$$. Redwood may be next in line or would a good basic douglas fir 2x4 be ok if properly primed/sealed b4 painting? Pressure treated wood won't work because of all the little indentations left by that process. Neighbor has the same dry rot problem and was quoted $10K to tear down and build something along the lines of what I currently have. I don't have that laying around and am hoping I can get away with replacing the deck material only for now.
