Caulking of windows, Must have tall ladder to reach upper story. Remove old caulk and then ReCaulking Just 5 inches up sides and across bottom of glass panes. Not All windows on home need done, some are another brand and do not need caulked. First level - Double door, (7) windows. There are some needing done on second story - ones on sides of (4) home and (4) upper deck plus Double Doors on upper back of home. I have the caulk already. All the windows mentioned, you turn handles to open out panels. So for each window, there are two panels. One largest living room has three panels. I bought the caulk. If you work with another kind, just let me know, I will have it for you.
