How it works
Strip and prep
We scrape out all old caulk and clean the joint so the new caulk bonds to a solid, dry surface.
Apply and tool
We run a controlled bead and immediately smooth it with a tool or wet finger for a tight, even seal.
Inspect the line
We check every joint for voids or bridging and touch up anything that isn't fully sealed.
Problems we fix
- Caulk applied over existing old caulk, which causes the new layer to fail quickly
- Gaps at the base of exterior windows that let water infiltrate the wall cavity
- Paintable caulk applied in humid climates before it's fully cured, causing it to crack
- Air leaks around pipe penetrations in exterior walls that inflate heating and cooling costs
Caulking & Sealing in Columbia — FAQ
What's the difference between caulk and weatherstripping?
Caulk fills stationary gaps — around trim, pipes and fixed frames. Weatherstripping goes on moving parts like doors and operable windows that compress when closed.
Can I paint over caulk right away?
Latex caulk is typically paintable in 30–60 minutes once skinned over, but a full cure takes 24 hours. We use paintable formulas wherever you'll be painting.
How long does exterior caulk last?
Quality exterior caulk lasts 10–20 years in normal conditions, but joints that move with the building — like door frames — may need attention every 5–7 years.
Caulking & Sealing across Columbia
Columbia's long, hot, humid summers are hard on homes — HVAC strain, swollen doors, deck and fence wear, and moisture around windows and caulk are all common. Older in-town neighborhoods bring hardwood floors, plaster and original millwork, while the Northeast and the Lake Murray side add newer builds with their own needs. Our pros are comfortable with both.
