Exterior Caulking and Sealing Prep Checklist

Open joints at trim, windows, and fascia let water in — caulk before the topcoat goes on.

Where caulk matters most

  • Window and door casings
  • Corner boards and fascia joints
  • Siding laps at penetrations
  • Porch column bases and rail attachments
Exterior trim prep and caulking
Sealed joints keep coastal rain out of siding and trim.

Product selection

Use paintable exterior sealants rated for movement and UV. Cheap caulk fails in the first hot season.
