What our customers say

“Marathon Seawalls and docks saved me so much time, money, and  aggravation all with one simple call. There boat lift team was able to come out and fix my lift on time and they solved a problem that the other lift companies couldn’t even solve! Very professional, very courteous, extremely helpful I would recommend them to anyone and everyone that has a boat lift here in the Florida Keys. Thank you MS&D I will alway choose you next time I have a problem.”
