Testimonials — See what our clients are saying about ACS.

"Our experience with Dave Duensing was invaluable. Dave brought creative skills and effectiveness to the project that added great value for our client. Dave and his company do not have to be micromanaged. He and his team are so experienced and capable that they work as their own entity making the rest of our project easier. Dave Duensing’s communication is so clear and he handles small issues without having to bring attention to them, and when there is a large issue, he's prepared to communicate very quickly and effectively."

Joe Jannopoulo Synergy Building, Corp Sarasota, FL

"“Most impressive for me is Aquatic Construction Services’ quality, and that my clients are always satisfied. Not many people can put boulders and stones together and make it look like a formation that’s always been there. On every joint project we’ve done, the craftsmanship and artistry have been superb. Dave Duensing’s team is exceptionally well-trained, passionate and motivated. They always shoot for excellence and their work always exceeds my expectations."

Raymond Jungles, FASLA Raymond Jungles, Inc. Miami, FL

"Dave Duensing and his company have completed three projects at our home in Islamorada FL that were designed by Raymond Jungles FSALA. Dave was extremely helpful, professional and detail orientated in the project meetings and interpretation of the design through the entire installation, and consistently exceeded all our expectations. If you are looking for a water and or rock specialty contractor who will bring experience and valuable input to the design and build phase of your project, you couldn’t find a better company to work with."

"I had no idea how complicated it is to build a waterfall and ponds the correct way, considering esthetics and long-term management. David brought a rare combination of creative vision, pragmatic construction skills and onsite management talent. He turned our rough vision into an aquatic habitat that enhances our image and working environment. Every day, our staff and visitors pause on our entrance bridge to enjoy the sights and sounds of the spectacular ponds and waterfalls he created. What a perfect setting for a wildlife organization, and our new headquarters!"

Wayne Schmidt, Board Relations Director (retired) National Wildlife Federation Headquarters Reston, VA

"David Duensing is very professional and informative. We are impressed with his intimate knowledge of natural rockwork and water effects, and his integration of landscape design into water features."

Christopher J. Brown, ASLA Senior Landscape Architect, VHB Orlando, FL

"David Duensing has a unique combination of talent and skill. He not only has the creativity to envision and design world- class water features, but also possesses the engineering and construction expertise to build lasting beauty."

William A. "Bill" Johnson, CGCS Firestone Specialty Products Company Indianapolis, IN

"David Duensing is a pleasure to work with: he is professional, courteous and always available to answer questions or explain the installation process. He always arrived on time and kept the site neat while working. His water features are truly works of art that add value and beauty to any landscape. We look forward to working with him on more projects in the future, and highly recommend his services to anyone seriously considering adding the element of water to their landscape."

Colleen Holmes Owner, New Leaf Landscape Agoura Hills, CA

"Dave’s 30 plus years of experience allowed him to provide an accurate cost estimate and to anticipate problems and avoid them. His masterful command of all aspects of the project allowed him to orchestrate the construction and improvise to include features that we added as the project evolved. Knowledge, experience, creativity and know how separate Dave Duensing and ACS from other rock and water feature builders. We are thrilled with the results and look forward to many years of enjoyment."

Lynn McRoy and Clinton Clapp Wilmington, NC

"It quickly became apparent that Dave’s vast experience and knowledge of the field would enable us to construct a state- of-the-art Koi pond which not only maximized its natural beauty but also minimized its maintenance requirements. He listened to our goals and preferences for the project and proceeded to design a feature which accurately reflected our objectives. Although one could probably identify less costly methods for constructing a basic water feature, it would seem a difficult task to locate a firm with more knowledge, experience, skills, and vision to bring such customized natural works of art to fruition."

Homeowners Gainesville, FL

"David B. Duensing & Associates is a pleasure to work with. Attention to detail and creativity are core competencies of his organization and his design stands on its own. Striving for clean lines, pure forms, and simple and clear color schemes, David's final compositions reflect not only the client's individuality, but the unique qualities of the site. I feel he is one of the best designers in the industry. That’s why I've retained him for my next project."

Mark Munley Vice President-Sales and Marketing Firestone Specialty Products Company Indianapolis, IN

"We put our trust in Dave and he created a water feature that far exceeded our expectations in every way. It is truly amazing how Dave is able to build a water feature and envision how the water is going to flow even before the water is turned on. With very little fine tuning he created a spectacular water feature for us to enjoy. We cannot recommend Dave highly enough. I honestly do not think there is anyone else who is capable of creating a water feature made of natural boulders that looks like it was always a part of the environment in which it was built. Everyone who enters our yard is struck with the beauty and tranquility of our pond."
