Caulking is the action of applying a sealing compound to joints and gaps in building materials.

Door, window and trim caulking provides thermal insulation and seals a structure from the elements.

Caulking for areas such as kitchen and bathroom surfaces provides resistance to water penetration.

Types:

  • Silicone - More difficult to apply, but remains flexible after drying
  • Latex - Water based for easy cleanup
