[Terry Porthcawl]

I have a wooden step leading from lounge onto exterior balcony.
There is a strong draught which I have tried to seal with clear ‘flexible’ silicon. As the step must be stepped onto to access the balcony, the silicon eventually becomes loose.
Can someone please suggest a remedy?
Thank you
