Finding handymen is NEVER easy:( Often, you have to use trial & error method and weed through several before finding one that is acceptably (never pefect) reliable, quality, will fix warranty issues and has decent prices.Try visiting a Home Depot 6-8am on a Saturday.

Just the other day I saw someone had used black sheet rock screws in the hangers on a brand new deck (non-permitted obviously, and not a single lag or any flashing on the ledger board, and they painted it immediately before the pressure treated lumber had even dried out so that’s going to peal in the first year, at about the same time that those sheetrock screws start to rust lol).
