Proper exterior caulking around your home seals out moisture and outside air while reducing energy costs and preventing costly repairs. It will also help keep out insects and small creatures seeking food, shelter and warmth. With some basic tools, supplies and a little work, your windows will be airtight and ready for the season.
WHAT YOU'LL NEED
Step
Check for drafts.
Check to see if any air flows through your closed windows. Also look at the caulk on the outside of the window. If there are visible gaps and cracks, it's time to re-caulk.
Step
Remove old caulking.
Be careful not to damage the door or window frame.
Step
Cut the nozzle.
Although this seems trivial, the proper cut will have significant impact on how thick and wide your caulk will be applied.
Step
Puncture the seal at the bottom of the nozzle using the caulking gun.
Step
Insert tube of caulking in applicator.
...and you are ready to go.
Step
Apply new caulking.
Use a step ladder if needed.
Step
Use your finger to add a finishing touch.
To get a really smooth finish, wet your finger and drag it along the bead of caulking compound.
Step
Clean up around the window or door with a wet rag.
Step
Wipe the nozzle of the caulking tube and replace the cap.
Step
Final tip!
If you're using paintable caulk, let the compound set for the recommended drying time before painting.
