Testimonials

What Our Clients Say

Boat owners across the Lowcountry trust Dexmarine for their marine electrical needs.

"Dexmarine rewired my entire 38-foot sportfisher after a fire damaged the electrical system. They were professional, thorough, and had us back on the water in under two weeks. The workmanship is outstanding."

Capt. Jim Reynolds Charleston, SC

"I've used Dexmarine for three different boats now. Their knowledge of marine electronics is unmatched in the Lowcountry. They installed a full Garmin suite on my center console and it works flawlessly."

Sarah Mitchell Mount Pleasant, SC

"Had a critical electrical issue two days before a charter trip. Dexmarine came out same day, diagnosed the problem, and had us running by morning. Absolute lifesaver — these guys know their stuff."

Mike Torres Isle of Palms, SC

"We hired Dexmarine for a complete electrical refit on our 50-foot trawler. From battery banks to panel redesign, every detail was handled with care. Highly recommend for any serious marine electrical work."
