Exterior Caulking & Sealing

Help protect your home from moisture and air intrusion by replacing deteriorated or missing exterior caulking around common joints, openings, and transitions. Exterior sealants can crack, shrink, separate, or deteriorate over time from weather and temperature changes.

Exterior Caulking & Sealing May Include:

  • Door and window perimeter caulking

  • Exterior trim and siding joints

  • Brick molding and door frame sealing

  • Utility and wall penetrations

  • Exterior gaps and transitions

  • Removal of loose or deteriorated caulk

  • Application of appropriate exterior-grade sealant

  • Caulking around repaired exterior trim

  • Sealing accessible joints against moisture intrusion

  • Preparation for exterior painting where applicable

Caulking is intended for appropriate joints and gaps and is not a substitute for proper flashing, roofing, siding, or waterproofing systems. Active leaks, damaged flashing, wood rot, deteriorated siding, or other underlying conditions may require additional repairs.
