Contractors...there ought to be a ...Wall of Shame... for the ones like that. There also ought to be a Wall of Honor for the good ones.
I had one, recommended by a neighbor, come out to put a little bulkhead on my lot. I specifically told him that I needed him to quote and use galvanized lag bolts. Sure enough, I looked, after he had 1/3 of the job done, and he was using the "plated" [censored]. Had him pull them out and put the right thing in.
My neighbor, on whose lot the contractor used the "plated" [censored] on...... has rusting bolts. My galvanized still look good. They just want to get around doing it right and save ten bucks or so. Sheesh... richg
