How to Close a Sunroom

Vacuum between the channels around each window and door -- where the edges of the windows and doors rest when closed -- with a vacuum attachment to remove debris.

Wipe the channels with a rag moistened with a solution of warm water and a few drops of a mild liquid detergent to remove any remaining dirt or residue. Wait for the window and door channels to dry.

Shut the windows and doors and engage the locks. If the windows or doors won't close tightly, tighten the hardware. If they still will not shut contact the dealer for repair.

Inspect the caulking around the windows or doors. Look for damaged pieces. Any pieces with holes or fraying require replacement.

Position the tip of the utility knife at one end of a caulk piece in the middle lengthwise. Run the knife down the length of the caulking to release it from the window or door. Pull off the cut caulk pieces.

Position the tip of the caulk gun at one end where the previous caulk was removed. Push out the caulk slowly as you move the gun along the length of the window or door until all of the old caulk is replaced. Use a moist cloth to wipe up excess caulk.
