Bidding vendor #2 just left the house. I'm breathing easier with their price, vs #1. I have one more suitor which we'll call #3 and am awaiting a call from them. My daughter used #3 on their house with success.
I'll call this case closed, and I'll be going down the professional road. I can cut, grind, paint, chip, weld, solder and slap Bondo with the best of them, and I'm known to be pretty heavy handed with bees and wasps (100% success, zero stings), but F'ing wood chewers get the professional boot from the old man.
