I installed a sliding glass door recently and recently noticed this. enter image description here

There seems to be a hole in the bottom small portion of the door between the sliding door and the static portion of the door. This leads right into the house and creates a huge space for air and other things to get in. What would be the best solution to fix this? I have called the manufacturer but it will take a while for them to get back.

  • So what did the vendor say? – Bryce Dec 19 '17 at 7:26
  • I have yet to hear back from them... the rep is either always in weeks of training and not available or on holiday... – Derek D Dec 20 '17 at 19:55
  • Turns out that the people I talked to never actually put in a service request... so as soon as they did the REP responded immediately. Shout out to the Central Texas Plygem rep for being so responsive – Derek D Feb 22 '18 at 6:01

Normally on the rear of the sliding portion of the door is a flap that engages at the last moment as the door closes. That may cover your gap. If you don't have one, you can add it (search for "sliding door draft stopper").

But looks like you could cut a block of wood to fit the gap (or, fancy, 3D print it). The strip insulation is available at most hardware stores.

But really, this looks like a manufacturing defect, not even an install defect.
