Remove your old door glass and frames from your door

1. Remove screw caps to expose screws (should be on the inside of the home, if installed properly). If the caps are painted over and difficult to remove, try a small flathead screwdriver and mallet/hammer to cut or knock them free.

2. Use a utility knife to score around the interior and exterior door glass frames to cut through any existing paint

3. With a friend outside holding the glass firmly into the door, remove screws. If screws strip out, try a stripped screw tool or you can use a drill to drill out the screws

4. Remove interior frame

5. Remove exterior frame and glass unit

Prepare your glass and door

1. Clean the opening in the door

2. Remove caulking from your glass (and clean from the face of the door). We recommend Goo Gone if you have sticky or stubborn caulking

3. Clean your glass with Windex and let dry for at least 20 minutes

4. If your new outside (exterior) plastic frame (the side without the holes for screw caps) is pre-caulked, skip this step. Otherwise, add a bead of silicone caulk (available in our accessories section) to where the exterior door glass frame seals with the exterior pane of glass. Then add a bead of caulk to where the exterior door glass frame seals with the exterior face of the door.

5. Within 10 minutes of applying caulk to the exterior door glass frame, press the frame down onto the glass (glass should be laid flat on risers like a block of wood with a towel to allow the frames to fully seat onto the glass). Push glass and exterior frame together and wipe any excess caulking that squeezes out

6. Let glass and exterior frame lay flat to allow caulk to set. We recommend letting caulk set for 8 hours before installation into door

Install into door


1. We recommend removing door from its hinges and placing it onto the exterior frame and glass

  • However, for sidelites or if you wish to keep door on its hinges (not advisable for large glass kits), have TWO helpers, one to insert the glass and frame from the exterior and one to hold the glass from the inside while the third person attaches the interior frame and screws everything together. WARNING: SEMI-STICKY CAULKING MUST HOLD GLASS DIRECTLY

2. Next snap the inside frame to the outside frame and carefully screw together. Do not exceed 15 pounds of torque. Over-tightening the screws may result in the frames warping or even cracking

3. Cover screw holes with included screw caps
