5/5

"Just Wow! From the design, to the ease of getting permits, to the workmanship and quality of the construction we are absolutely delighted with our new dock and our experience with Gary and the Enterprise Marine team. The end result is better then we ever could have imagined."

"Enterprise Marine Contractors removed my twenty year old deck and replaced with a newer and bigger deck. Jorge with Rosie's crew did a excellent job installing my new Pilings and new decking. Great workmanship with Integrity AAA++"

Russell Firesinger
5/5

"Shout out to Gary and his crew. They built out my dock, wet slip and lift slips about 4 years ago. Gary told me what to expect in a major hurricane and built to withstand such a storm. We just came out of 2 major monster hurricanes with no damage to the infrastructure nor to either boat. Very happy and Enterprise is very reasonable also. Thanks Gary and the guys."
