DIY vs. Call a Pro
Caulking is one of the most impactful DIY maintenance tasks. Remove old caulk completely with a utility knife or caulk remover tool, clean surfaces with rubbing alcohol, apply painter's tape for clean lines, and use a caulk gun with steady pressure. Smooth with a wet finger or caulk tool.
Call a professional when:
Hire a professional for large-scale exterior caulking, if mold remediation is needed behind existing caulk, for specialty sealants (fire-rated, structural), or for hard-to-reach areas like upper-story windows.
