Hi past few years I've noticed our patio doors seem to let a draft in I've tightened up the keeps messed with the hinges outside etc and they have improved but you can still feel the cold in the bottom corner. Noticed the rubber gaskets on the doors look a bit worn although the house is 9 years old should they need replacing yet? I've ordered this online but noticed my gaskets are a different shape :unsure: that'll teach me for not checking :cry:. https://smile.amazon.co.uk/dp/B07W998GD1/ref=cm_sw_r_apan_glt_fabc_ZXBQN0JCVBBSXPXKVBWE?_encoding=UTF8&psc=1 The one that's around the doors currently is this type Would it be ok to switch them or will that make it worse? Not sure if the current seal is this type?
