THE SHORT ANSWER
How to Estimate Exterior Caulking
100 ft of silicone joints around windows with 6 labor hours at $50 totals about $450.
Linear footage drives the bid
Caulking prices per linear foot. Walk the building and measure every window, door and siding joint to seal.
- Caulking length
- Windows / doors / siding
- Silicone vs acrylic
- Labor
Surface changes the factor
Door perimeters need more prep and heavier sealant; long straight siding joints are faster per foot.
Silicone vs acrylic
Silicone stays flexible and resists weather but is harder to paint; acrylic paints well but is less elastic. Choose by exposure.
Prep the joint
Remove old caulk and clean before sealing, or the new joint fails. Count prep in the labor hours.
