Caulk seals joints where two surfaces meet and may move differently. It can fail through age, movement, poor adhesion or moisture, so the old joint and substrate should be evaluated before new sealant is applied.

Bathrooms and Kitchens
Tubs, showers, sinks and counters commonly use flexible sealant at changes in material. Failed caulk should be removed back to a suitable joint rather than covered with another bead.
If grout is failing inside a tiled field, use Grout Repair instead. Grout and caulk serve different purposes at different joints.
Trim, Windows and Interior Joints
Caulk can also close selected gaps at trim and window interfaces. If the gap comes from a damaged frame, large movement or exterior water intrusion, sealing alone may not be the right repair.
Window Weatherproofing and trim repair services cover those conditions in more detail.
Moisture and Mold Boundaries
New sealant should not be used to hide an active leak or damaged substrate. NY-GoodHome does not claim mold remediation or full waterproofing through a caulking service.
