UKMC was a pure pleasure to work with. From the very beginning we were treated professionally and courteously. The job turned out better than we imagined. David DeBrule and company are the best in all the Keys!

The crews were very respectful of our property. They assured the job was done correctly. Even when we thought the job was finished, they showed up to clean up any minor imperfections in the cured concrete and sealed all surfaces. This is a company who takes pride in their work.

I have found Upper Keys Marine to be the best contractor I have ever hired. David is a true professional and takes care of his clients needs. The quality of work and craftsmanship is second to none. I look forward to many years of enjoyment of my new dock and lift.

Very good quality of work. The only flaw is the occasional difficulty in communications. Overall, I am well pleased with the outcome.

UKMC was such a pleasure to deal with. The work was completed within two (2) days after the permits were approved. The work was done correctly and professionally. UKMC was hired to redo the work from a different dock/lift builder in Key Largo. The previous dock builder installed the wrong equipment and it collapsed with my boat on the lift.
I would recommend UKMC to anyone who is in need of any dock work.

If I said what I really thought it would sound like an infomercial. So in short: excellent workmanship and materials. Fair and honest pricing. Job site well kept. Knowledgeable about products they represent and local environmental/building codes. Besides all this David and Dawn couldn't be nicer, making the construction process a pleasure instead of a torture.

We have used them twice on our lift and both times it has been an excellent experience. David is professional, dependable and polite. Gives great service.

David was instrumental in our successful difficult permitting process, and the Government shut-down didn't help. In spite of all, the job was (both lift and dock) timely delivered. The job site was always immaculate and the finished product was superb.
Ocean Reef
Dave as owner was very hands on. It was great to deal directly with the owner. Special requests were all done as requested and even though this was his busy season, Dave completed the dock on time and as promised. I was in New Jersey while all the work happened and it was glitch free.
Tom Keller

Your crew was very professional, courteous and hard working. The materials and craftsmanship are the best one could ask for. We are extremely satisfied.

Upper Keys Marine once again delivered a quality job in a timely manner and at the best price around. They have done numerous projects in our basin, both large and small and the end result is always the same. A highly satisfied customer.

Met with David at 2pm and the dock was repaired by 5pm...same day. And the work was excellent and reasonable in price. What is not to like about that?!

My dock and lift are going to need more work. I am not skilled in such things. I feel like I found a reliable "partner" for these issues today, and I am delighted to team a company that is experienced, straight-forward and capable. Solid.
John G.
Key Largo, Fl
First let me say - Upper Keys Marine is one of the most professional builders I have ever worked with. They cleaned up daily, showed up early and stayed late - and this was all done during the holiday season. Plus the DeBrules managed the job like hawks. Always there early and late to make sure things were correct.

Not all went perfect, but when issues arose, and in building they do, Upper Keys stepped up to the plate. Not without a price but done in fair, reasonable and professional way. There is no doubt they run one of the best businesses in the Keys.

Let it be known, I have never owned a boat or a house on the water before. I didn't know the questions to ask, or the quality differences in a dock. They all seemed to be the same. However, now that I have seen first hand how my dock was built, their quality is apparent. They router the edges of everything - even the stuff under the dock. They trimmed out the sides, even though it looked good with out it, but it looked great with it. Their screws were surgically aligned, and their boards were spaced with precision.

Upper Keys builds docks they would want at their house. So without hesitation - Upper Keys Marine Construction is the company to use.

This was a very pleasant experience. Top notch work and not one single thing during the process caused any stress or aggravation to my wife or myself. I would recommend them to anyone. That is saying a lot, I rarely do that to avoid problems

From start to finish my experience with Upper Keys Marine Construction has been fantastic. The dock that they built for me came in on time and on budget. The professionalism and attention to detail in their work went above and beyond my expectations. Through out the process, they answered all of my questions and provided valuable recommendations. Even upon completion of the dock, they still came back to check in on me and make sure that I was satisfied and made any adjustments that I required. Not only is the dock beautiful, but the quality with which they built it ensures it will be around for a long time. I will definitely utilize their services again and would have no hesitation in highly recommending them to anyone who would ask my opinion.

I want to thank you for the excellent workmanship and commitment to excellence that you have shown regarding the dock restoration here in Marathon. The dock is truly beautiful and obviously well constructed and the extra touches you completed make a huge difference. I have been out to the dock both during the day and during the evening. Everything works well. My overall impression is that through your efforts, this dock has transformed into more of a work of art than just a job.

Mr. DeBrule (“D”):

I would like to take this opportunity to bring attention to the fact that we at The Phoenix Environmental Group, Inc. sincerely appreciate the professional manner in which you and your project team completed the installation of the new water lines to Little Palm Island. It was obvious from the start of the project that you and your team intended to install these new lines in a manner that resulted in no measurable adverse impacts to the sensitive benthic habitat within the national marine sanctuary/aquatic preserve. Your attention to details associated with this difficult installation work and your attention to the safety of your crew and our on-site environmental consulting staff, was truly impressive and greatly appreciated. This entire project was completed in accordance with all federal/state permit conditions and reflected the highest degree of Best Management Practices.

Again, thank you. It has been a pleasure working with you and your crew. We look forward to having the opportunity to work with you again soon.

I would like to take this opportunity to thank you and your brother personally for a job well done on the Banana Bay Marine in Marathon. Not only did you do what you said for the price you quoted but you finished the job ahead of schedule. The quality of your workmanship was great and your employees were polite, neat and very professional.
In today’s world of poor workmanship it was a pleasure to see people that take pride in their work and the finish product.

I would like to express our gratitude for the exceptional work your company provided in demolishing the existing docks in the Florida Bay Boat Basin, and replacing them with new concrete floating docks and fixed aluminum piers. The work your company performed was nothing short of outstanding. Thanks entirely to your own initiative, you were able to perform the work without impeding our tour boat concessions operations, or the continued use of the very active boat ramp.

Your company performed the work with complete enthusiasm from start to finish, and never lost its desire to provide the best possible product.

Too often people write complaint letters. I would like to congratulate you and your crew on the excellent job you did on rebuilding of all of the finger piers at the Florida Sea Base. The workmanship is excellent, your crew was extremely easy to get along with and very courteous.

I just wanted to extend a Scout’s salute to a great company and a job well done.

The dock turned out beautifully, your workmanship was extraordinary and it has been enjoyable to get to know you and work with you.

Kathy Klock
Although the ramp has been open for less than a month, we have received nothing but very, very positive comments from everyone that has used the ramp. The construction is first class and has met our requirements to handle boats of various sizes, shapes and types.

Please convey our sincere thanks and appreciation to your sons, and also to their work crews. The communication, workmanship and implementation were flawless. Everyone who worked on the project was both professional and congenial. We cannot say enough to express our total satisfaction.

As both a home owner and a custom home builder, I wanted to say Thank You. Thank you for doing a First rate, First quality job on time and on budget. We couldn’t be happier with the honest and integrity that your company portrays.

I would like to thank you for our wonderful new dock. It was certainly worth waiting for. I don’t think any other dock company could have built an almost 400 ft. dock with the precision your company did.

You and your family and your company have exceeded my expectations and I thank you whole heartedly
