I just discovered the caulk on the outside of my windows is splitting and water has been getting in. Is there anything I should do before I reseal the windows back up with new caulk to prevent mold etc.? Thanks
Remove old caulk and ask your local big box home improvement store what type of caulk to use for your application. There may be differences based on paint or stain, weather, siding material, etc.
First take a sharp knifepoint and check the wood around the areas for rot. Fix any soft spots first. Remove as much of the old caulk as possible with the knife all the way around the windows and replace the caulk with a urethane or polyurethane caulk. This caulk is far superior to any other type available at you local home improvement stores. It will remain flexible for many years (unlike many caulks), adheres well to most any construction materials, and is paintable.
