How to Remove Condensation From Between the Panes of a Skylight

Drill Holes in Glass

• 1

  Affix a 3/8-inch diamond hole saw bit to the cordless drill. Adjust the choke located immediately below the drill opening to tighten the saw bit. Grasp the choke firmly while pulling the drill's trigger. Test the tightness of the bit by pulling the drill's trigger. If the drill bit doesn't spin properly or falls out, repeat the process until the bit is secure.

  Holding the spray bottle in one hand and the cordless drill in the other, drill one hole into the bottom left corner of the glass pane directly facing the exterior side. Continually spray water on the drill bit during this process. Don't allow the bit to be without water until the drilling process is complete. Drill a second hole in the bottom right corner of the window pane using the same procedure.

  Insert one piece of 3/8-inch plastic tubing into the drilled hole in the lower left corner of the glass pane. Stop the insertion when the tube is 1/2 inch inside the pane. Open the silicone latex tube by piercing the tip of the applicator tube with the pin provided. Apply silicone latex around the edge where the plastic tubing meets the window pane. Ensure that the latex covers the entire area. Repeat this process for the hole in the lower right corner of the window pane.

Insert Scrub Pad

  Insert a small piece of disposable scrub pad into the plastic tubing. The piece must be large enough to prevent insects from crawling into the tube and small enough to allow air to flow through the tube. Avoid placing the piece deep into the tubing as this can make it difficult to remove.

  Monitor the condensation status of the glass panes. If water vapor isn't escaping from the window panes, remove the current piece of scrub pad from the tubing using a pair of tweezers. Place a smaller piece of scrub pad into the tubing and continue monitoring the skylight's condensation status. In proper conditions, it can take two to 12 weeks for all the condensation to evaporate.

  After the condensation evaporates completely, apply silicone latex to the ends of both plastic tubes. Cover the ends completely until the latex closes the gaps, creating an airtight seal.
