Door seals replacement.

[mrfusyi]

Hi guys. during last cleaning, found that my ori bmw carpet on front passenger side was kind of damp and wet but the rubber mat above was dry. I suspected water was seeping in, and after googling through find that it may have be due to bad door seals.i noticed also when i close the door, it didn't seem to be flush with the rest of the car and i can hear wind noises while cruising. thinking of getting the seals replaced but afraid of what it'll cost. anybody had their door seals replaced recently? need to know how much and how long it'll take.thanks!
