We just bought a place and are looking for some data points/recommendations a) Attic clean-up/sterilization and b) 200 amp main panel upgrade in the San Diego, areaThe quotes we received are basically insane, even accounting for the recent inflation... one guy wanted ~$3500 to clean/sterilize/seal up two metal mesh openings (and that's including a $500 "discount" for doing it before Thanksgiving).
