Caulk seals a change of material. Weatherstripping seals a moving sash or door. Keep them separate. Failed beads at a tub or an exterior window flange are how water reaches a cavity. This page is the household map. Exterior comparison detail lives on comparing caulking services.

Joints worth listing in a request

Bath: tub-to-tile, shower floor-to-wall, inside corners, tub-deck ends.

Kitchen: sink-to-backsplash, counter-to-wall.

Exterior: window and door perimeters, penetrations, stucco-to-trim, stucco-to-slab.

Interior trim: base and crown only if you want those beads in the same ticket.

Do not claim every San Diego house “should” have all of these intact as a regulation. It is a practical inventory.

Product families

100% silicone for wet, moving joints (tubs, showers, many sinks). Not paintable. Cure time is on the tube.

Paintable acrylic latex for dry interior trim. It is the wrong product in a shower.

Polyurethane or hybrid for many exterior stucco and concrete joints. UV and movement ratings are on the data sheet. There is no published county lifespan that applies to every bead. Coastal salt can chalk and embrittle acrylic faster than inland. Re-inspect when you see chalking, brittleness, or a clean peel. Do not calendar a two-to-three-year rule.

When the old bead has to come out

Replace, do not overcoat, when the bead is split, pulled away, embedded with stain through the body, or flaking. New over old is the usual failed DIY pattern.

Removal time is not a 45–90 minute standard. Corners, silicone residue, and cultured marble change the work. Dry the joint. Silicone will not bond to a wet ledge. Exterior work needs a dry wall, not a marine-layer morning if the label forbids it.

A captured Unstoppable Handyman San Diego recaulk page listed labor and materials as consistently $255 for a standard bathtub-and-bathroom-sink combination or a standard kitchen sink plus countertop-to-backsplash seam when photos confirm the area is suitable. A captured Taskrabbit San Diego sealing listing said caulking services begin at $40 per hour in San Diego. Use those as competitor examples. Get a written joint list.
