Testimonies


Collier did a great job with our new dock! They were easy to work with from start to finish and everything turned out fantastic. We had them build a dock that included a boat lift, pwc lift and drainguard. I would highly recommend.

Collier Seawall & Dock exceeded our expectations. We are very grateful for their commitment to our needs and their attention to detail. They are the only ones we will recommend for anyone needing dock work
- Ashley Mc Phail

I want to give a big shout out to collier seawall and dock for being the most professional marine construction company on Marco Island! They care about the small jobs just as much as they do the large ones. I had a small repair and they immediately came and fixed it for me. Thank you for everything! Highly recommended.
- Rose Peeples

Collier Dock & Seawall just finished replacing our dock. We have nothing but praise for their attention to detail and high level of craftsmanship. They even started 2 months earlier than planned. We are so happy with our new dock & boatlift! (Need to get some matching chairs! )
