Duncan Seawall Dock-Boat Lift

We recently had our dock and boat lift rebuilt by Duncan Seawall in Sarasota, FL, and we couldn’t be happier with the results! From start to finish, the entire experience was nothing short of exceptional. We upgraded with flow-through decking, new pilings, new lights, and shore power/water, all of which were installed flawlessly. The craftsmanship and attention to detail exceeded our expectations. Special thanks to our project manager, Donny. He was absolutely fantastic! Donny kept every aspect of the project running smoothly and provided outstanding real-time communication throughout the process. He made sure we were informed every step of the way and was always quick to answer our questions with professionalism and expertise. His dedication and customer service truly set this experience apart. If you’re considering dock or seawall work, I highly recommend Duncan Seawall. Their team’s professionalism, quality of work, and customer-focus are top-notch. We are thrilled with our rebuilt dock and boat lift—it looks amazing and functions perfectly. Thank you, Donny, and the entire Duncan Seawall team!

Duncan did the original install of our dock & has always maintained it. They are very responsive with every call or issue we have had. After hurricane Helene destroyed most of the dock we called and they came out and gave us the cost for replacement. Don Stone & the crew captain made sure everything was perfect during the rebuild. Mark Parsons worked with us on every part of the replacement & follow up along the way to make sure everything is to our liking. A great experience working with them for all work

Duncan Seawall went above and beyond repairing our pool deck that was damaged from the hurricane. Great communication during repairs. All employees were friendly and professional.

Duncan replaced our old floating fuel dock with a Golden built top of the line model. The work crew did an outstanding installation job. Both job supervisor Donnie and sales person K.C. were very responsive in answering questions during and after the installation. Great job Duncan Marine!! Thank you Tropic Isles Co-op Marina near the south end of Terra Ceia Bay. Least expensive fuel on the water from the Green bridge to the ICW.

I spent 25,000 to have a concrete piling replaced and the gangway attached to the dock! A week after I paid the gangway became detached and dangerous. I called my representative many times with no return call. After two weeks with no return calls or texts I decided to call Mark the owner. I left two messages for Mark with no return call. Evidently this is their company culture. They won’t last treating customers this way. Next stop is the BBB.

Duncan Seawall has done many jobs for me over the years. The latest project was raising my seawall to better protect our property from storm surges like Helene. In every case, they performed quality work on time and on budget. Mark Parsons is a true professional, and a pleasure to work with.

Duncan Seawall didn't meet my expectations they blew it out of the water. This wall was not a easy job and had multiple obstacles from the logistics of working on the wall to dealing with the city on permits and code enforcement issues. Just wanna highly recommend them to anyone looking work to be done. I've been in construction in Northern Illinois for 30 plus years and somewhat particular when running my company so hopefully this review will come with some weight. Thank You Sal

I have been a customer of Duncan since July 2017. I hired them to remove an outdated seawall, install a new wall, boardwalk dock and 16,000 lb boat lift. All the work was completed on time, within proposed budget and with a competent crew. I have recently worked with Duncan after last year’s hurricanes damaged my lift. I called the operations department, explained my situation which was both structural and electrical. Within a week the crew was on site, and I was back boating. I have always been pleased I chose Duncan Seawall

Worst service ever. Called six time without a call back. When i finally heard back from them, they said they would take care of the problem (lift wouldn't lower). That was a month ago and the lift still hasn't been fixed. I know that everyone is busy after Helene, but this is ridiculous.

Exceeded expectations when repairing poorly installed shore power originally done by another company

Duncan Seawall not only does amazing work over and over, but their customer service is great. I cannot recommend them highly enough. They do such beautiful work, help you decide the best route to go and make everything easy. Even if there's an issue with something, they make it pain-free. If you're building a dock, or a seawall or you're refurbishing, I highly recommend them. Not only did they build us the most beautiful dock, they also refurbished our rip-rap.

We have purchased 5 boat lifts and 2 docks from Duncan Seawall over the years, with satisfactory results most of the time. This experience was over the top disappointing. The communication was terrible. We never knew what they were doing or when they would do it. We had to argue with them for the configuration we wanted--at three junctures, they were certain they knew what was better for us. We could not communicate at all with the electrical crew due to language barriers. If we had not, by chance, been at home on the days they worked, the project would have been a disaster. This was a very, very bad experience that has left a lasting bad taste. This is the last time we will use Duncan. Just speculating: it may be that COVID has left the company with staff shortages and the skilled crews are being assigned to the commercial projects.

I have called them 3 times in the past 2 month about a boat lift repair. The secretary has told me 3 times that Jose or Terry would call me back and they never did. I have been a customer for years so I can't even imagine how they would respond to a new customer. John D

What a joke! Had these clowns build a dock and boat lift. Very unprofessional. NEVER return calls or emails (except before contract is signed). Did a crappy job in general building the dock a lift. And left a ton of crap on the property and in the water that I had to clean up like a 5 gallon bucket of scrap hardware, scrap wood, screws, and even a crappy home made raft that they just let float around the neighborhood canal. Called and emailed several times to have it picked up. Dock built in November 2020, it May 2021 now and it's still there. Also, they told me that they would rough-in the plumbing for a hose spigot from the dock to the end of the walkway and conveniently lost their memory when they finished the dock, so, they don't keep their word. Don't put the ladder that they supply in the water. We had ours in the water overnight and it turned/tarnished grey. You'll love the nails that they use when you see the heads rusting after a few weeks. YES, NAILS. This company is awful.

We first contacted Duncan Seawall in April of this year to build a boat lift at our dock. They told us it could be a couple of months before they received the necessary permits. Three months later, my husband checked with them on the progress of the permits, and found that the company hadn't even applied for them. Once they did apply, the county provided the permits within weeks. Because we needed 220 volt power at the dock, Duncan sent an electrician to install the necessary wiring. The electrician had to dig through the yard, and in one area, he cut through not only the piping for our irrigation system, but also the wiring, which is in a protected area below the pipes. The electrician admitted that when he hit something hard, instead of checking to see what he was hitting, he just slammed harder with the shovel until he broke through. My husband complained to Duncan, and was told that the contract we signed absolved them from any liability for destroying things while installing the lift. But they agreed to come out and fix the wiring. Unfortunately, the electrician who did the "fix" didn't do it in a way that it would be permanent, and he got caulk or something inside the pipes for the irrigation system, on top of that. Duncan was completely unresponsive to my husband, who ended up having to repair both the wiring and the pipes himself. Luckily he is an electrical engineer and skilled at a lot of home repair, but he has already spent 4 hours on the job and it isn't completely done. The only good thing I can say about Duncan is that so far, the lift seems to be properly installed and functional.

Best dock and seawall company in town. Awesome follow up, fair pricing, and they show up for appointments too. They are my top recommendation for any dock, seawall, or lift repairs or installs.

I cannot recommend this company. I spent over $24,000 with them, so you'd think I'd be a valued customer. Think again. Communication was terrible. Promises made and not kept. I knew nothing, even with over 40 years Engineering Experience. Boat Lift: Posts cut down too low- a real head knocker. Boat support stringers were put in without washers on the wood-side, but washers put on the metal side. Made no sense. When I confronted them, "our foreman has over twenty fours-years experience". I guess I'm stupid, but the when the heads of the bolts bury themselves into the wood and the stringers loosen, I guess that's my imagination. Argh!!! Check out Ram Marine.

Super professional experience w/this company! They showed up as expected, presented a fairly reasonable (slightly high IMO) quote, started & completed the work as scheduled & their employees/workers were professional & cleaned up after themselves!! After the job was over, I decided it was worth every penny & we will be using them for our dock repairs next year.

We recently used Duncan for a boat lift replacement, sea wall replenishment, and a new Sea Doo Lift. We are extremely pleased with the results and the 3 teams that did the actual work. The Golden lift is noticeable nicer (quieter, faster, smoother) than a similar lift we had installed at another property just 2 years ago, by another local vender/contractor. The Sea Doo lift is a single post unit that works extremely well. The sea wall looks much better and will prevent any further erosion from the large boats on the ICW. We also especially appreciated Joseph's knowledge of the rules & regs for the area and of the product lines. The showroom was fantastic in helping us make our decisions. We will use them again, for other projects!

I dealt with Mark Liebel & the crew at Duncan Seawall for my project on Anna Maria Island. From the time of design through construction, I felt totally comfortable and that I was dealing with a quality organization. I spoke privately with several employees during the selections process and during construction, and employees love working for the company--that showed me something. Once my project got through permitting, their massive barge with crane floated to the site and got working. I paid a reasonable price for a top quality job. The site was cleaned every day, the project was done flawlessly, and I would say the ONLY contractor that did what they said they would do, no shortchanging the customer, and got things done on time with NO hassles. Highly recommended.

Duncan Seawall installed a seawall and dock for our property last Fall. Not only were they patient as we moved through the process, making changes along the way, but they also clearly explained how the process would work, the time frame involved and how each modification to the original design would change the pricing. Their workers were always conscientious and respectful. The completed seawall (approximately 160') and dock are both beautifully finished with a quality of workmanship that shows in all the details! Thank you, Steve, for a job very well done!! The Campbells

There are very few businesses today that cater to their customers and actually fulfill expectations. Duncan Seawall has this figured out and it's easy to understand why they have the premier dock and seawall reputation in west Florida. Not only did Mark Liebel build me an amazing dock but his service manager Terry continues to roll out the red carpet when service needs arise. If you are looking for a quality build with a company that you can trust, the search should start and end here.

The most challenging part about building a new dock is getting a permit and Duncan Seawall does an outstanding job helping their clients navigate this often difficult process. Joe Pietrucki, the permitting expert, is a consummate professional and handles all of the details while keeping the client well informed. This company understands customer service and made me feel as though my project was the most important one that they were working on. Highly recommended!

I don't understand why the negative reviews... Kind of fishy coming from folks who have written such few reviews. Personally I love Duncan seawalls and I have had GREAT customer service from them.

My husband and I chose a Truline product to cover the exterior of our very old and ailing seawall. Their employees, Enrique and Paulino were punctual, reliable, respectful and worked very steadfastly to keep our job timeline to a minimum. The work went smoothly with not much impact to the surrounding property. Our site manager, Don was most conscientious to ensure our entire job ran smoothly and was done to perfection. Even the managerial staff, offering quotes, handling permits, sending email replies, all did so in a constant forward motion to let us know we were being treated with all their well-intended considerations. We could not be happier with the end result of our seawall and would definitely recommend Duncan to anyone considering a future renovation or replacement on their seawall or boat lift. Duncan also replaced my neighbors entire concrete seawall 2 years ago and it looks beautiful. Duncan has also done dredging throughout my whole neighborhood on Sarasota Bay for our Association to keep our private channels cleared and navigable. They have a very broad work experience and it shows in their results.

Duncan last year replaced our boat dock with a boat platform. They were awesome! On Christmas Eve day, the platform wasn't working and we called Duncan in a panic. All the repair guys were gone for the Christmas holiday, but the owner of the company offered to come out and seee if he could help.The owner spent 2 hours trying to help on Christmas Eve afternoon. Ultimately, he determined no power was getting to the dock. While the owner isn't an electrician, he did arrange for one of their electricians to come out the next business day. The electrician determined the original installer of the boat lift (not Duncan) ran the power through the water! Over time, the line corroded and shorted out. Instead, at low tide the next day, the Duncan electrician ran the line attached to the underside of the dock. Duncan was responsible, professional and timely. I clearly will use them again for any dock or boatlift issues we encounter!

We contracted Duncan Seawall to put in a seawall and dock for us. From the owner, sales, front desk and workers, they all displayed extreme professionalism and knowledge of their jobs. We are extremely happy with the job and would recommend this company. Their customer service is unparalleled. They were happy to make changes that we requested after already signing the contract. They just re-worked the plans and submitted the new contract. The work was exemplary; both on the seawall and the dock. Thank you Duncan Seawall. Bob and Pat White

We just had Duncan replace our 70 year old seawall and cap on St Armonds. Mark Parsons did a great job laying out all of our options. The team came with Donny as the superintendent an completed the job on time, on spec, with minimal disturbance to our landscaping. There was excellent communication throughout the process. We highly recommend Duncan for all your seawall, cap and dock work in the greater Sarasota area.

Terrible experience!! The owner of this company not only refused to correct his faulty work but used foul language while speaking to me when I confronted him. The boat lift they installed broke after a few months without even having been used; I didn't even own a boat yet! This guy is the highest degree of unprofessional. If you're looking for QUALITY work, STAY AWAY FROM THIS COMPANY!

My husband and I hired Duncan Seawall in early 2016 and they were terrific from the time they came to quote, provided the quote within 24 hours as promised, provided ideas and solutions. They got all the permits done. Started right on time, delivered a high quality product. We appreciated the attention to detail, down the the grease on the washer on the boat lift, nothing was overlooked. We were glad we went to their showroom, it had a ton of information and ideas and given we will live with our new dock for 25-30 years, we're glad we put the effort in to seeing all the choices in a life size format. Ask for Mark Liebel to come and quote your project and ask for Mark Parsons to be your project lead. Recommend them highly. We'll post pictures of our lovely dock on Key Royale Holmes Beach as soon as we can.

I was a little harsh on this Company with my initial review and would like to make some corrections. I am well satisfied with the construction of my dock and could have saved some hard feelings if I has simply contacted this Company when I noticed some things that I did not like instead of using the internet to express my disappointment. The Duncan representative has agree to do what he can to make me a happy customer and told me that a couple of the problems can easily be solved and would have been solved earlier if I had contacted them about my complaint. The bottom line is the wife and I both love our dock and think we got our monies worth and would use this company again as well as recommend Duncan to everyone interested in building a dock.
