Welcome to LeBlanc Decks, a place where outdoor spaces are treated with the same seriousness, engineering discipline, and long-term thinking as any major structural investment in your home. We are not a general construction company that occasionally builds decks—we are a dedicated, specialized deck-building firm focused entirely on creating outdoor living systems that are designed to perform, endure, and age gracefully over time.
From the moment you arrive here, our goal is simple: to give you clarity, confidence, and a real understanding of what a properly built deck should look like when it is engineered without shortcuts. Whether you are planning a small private patio extension, a large multi-level outdoor living space, or a fully customized architectural structure, LeBlanc Decks exists to turn that vision into something structurally sound, visually refined, and built for decades of use.
Founded in 2002 by Rian LeBlanc, our company has grown from a small landscape design background into one of the most trusted names in premium deck construction in North America. Over the years, we have refined not just our craftsmanship, but our entire building philosophy. We believe that outdoor structures should not simply “look good” when they are finished—they should remain stable, safe, and beautiful long after installation, through changing seasons, weather exposure, and everyday use.
What sets LeBlanc Decks apart is not just the materials we use or the designs we create—it is the system behind everything we build. Every project is guided by a strict construction standard that prioritizes structural integrity, moisture resistance, framing precision, and long-term performance. We design with the assumption that every deck we build will be tested by time, and we build accordingly.
We also believe that transparency is just as important as craftsmanship. That is why every client we work with is given access to a structured project system that keeps them informed at every stage. From initial planning to final walkthrough, our process is designed to eliminate confusion and replace uncertainty with clarity. You always know what is happening, when it is happening, and why it is happening.
At LeBlanc Decks, we do not measure success by how quickly a project is completed—we measure it by how well it performs years after completion. That mindset influences everything: our engineering decisions, our material choices, our framing systems, and even our finishing details. We are committed to building outdoor spaces that feel solid underfoot, remain visually consistent over time, and require minimal long-term maintenance.
We invite you to explore what we do, understand how we build, and see why homeowners and commercial clients across Tennessee and beyond choose us when quality truly matters. This is not just about adding a deck to your property—it is about creating an outdoor structure that becomes a lasting part of your home’s value and lifestyle.
Understanding Who We Are and What We Stand For
LeBlanc Decks is a premium outdoor construction company specializing exclusively in custom deck systems, engineered outdoor structures, and sustainable building solutions. Our focus is not broad construction—it is precision deck building backed by years of experience, technical expertise, and a refined construction methodology that eliminates the guesswork commonly found in the industry.
Originally established in Bend, Oregon, and now headquartered in Knoxville, Tennessee, our company has evolved through decades of hands-on field experience, material testing, and structural refinement. This evolution has shaped a very specific identity: we are builders who prioritize performance over shortcuts, structure over surface, and longevity over temporary appeal.
At the core of our work is a belief that most deck failures are not caused by bad design intent, but by compromised execution—small shortcuts that accumulate into long-term structural problems. That is why we built what we call the LeBlanc Build Standard, a consistent system applied to every applicable project. This standard governs everything from foundation systems and framing techniques to fastening methods, moisture protection strategies, and finishing details.
Our introduction to every project begins with understanding how the space will actually be used over time. We consider load conditions, environmental exposure, drainage, material expansion, and long-term maintenance expectations before a single board is installed. This allows us to design and build structures that are not only visually appealing on day one but remain structurally reliable years into the future.
We also place strong emphasis on material intelligence. LeBlanc Decks specializes in wood-free composite decking systems that eliminate many of the common issues associated with traditional lumber, such as rot, warping, insect damage, and moisture absorption. These materials allow us to build outdoor spaces that maintain their appearance and performance with significantly reduced maintenance requirements.
Beyond materials and engineering, we focus heavily on process. Every project follows a structured lifecycle that includes planning, design coordination, permitting, construction scheduling, daily progress documentation, and final quality review. This system ensures that no detail is overlooked and that every client remains fully informed throughout the entire process.
Transparency is a defining part of our identity. Clients are not left guessing about timelines, progress, or decisions. Instead, they are provided with a dedicated project portal where updates, photos, documents, and communications are organized in one place. This level of visibility is not an optional feature—it is part of how we operate on every project.
We also believe that outdoor construction should be environmentally responsible. Our approach to sustainability includes the use of recycled materials, reduced reliance on chemically treated products, and partnerships with North American manufacturers to minimize transportation emissions. These choices reflect our commitment to building responsibly while still delivering high-performance results.
Ultimately, LeBlanc Decks exists for clients who value long-term thinking. We are not the right fit for quick, temporary, or low-budget installations that prioritize speed over structure. Instead, we work with homeowners and commercial clients who understand that a properly built outdoor space is an investment—one that should add value, comfort, and durability for decades.
As you continue exploring our company, you will see that everything we do—from our engineering methods to our communication systems—is built around one guiding principle: build it right the first time, and build it to last.
About Us – LeBlanc Decks
LeBlanc Decks is a specialized outdoor construction company dedicated exclusively to the design and construction of high-performance deck systems and engineered outdoor living spaces. Founded in 2002 by Rian LeBlanc in Bend, Oregon, the company was born from a background in landscape design and construction technology, but quickly evolved into something far more focused and refined: a full-service deck-building firm built around precision, durability, and long-term structural thinking.
From its earliest days, LeBlanc Decks was never intended to be a general contracting company that builds “a little bit of everything.” Instead, it was shaped by a deliberate decision to specialize in one thing and master it completely—outdoor decking systems. That focus allowed the company to develop deep expertise in structural framing, material science, moisture management, and long-term performance engineering, all of which are essential in building outdoor structures that must withstand weather exposure year after year.
Over time, LeBlanc Decks grew into one of the most recognized decking specialists in Central Oregon, eventually becoming a premier dealer for Deckorators composite systems. The company also operated one of the region’s only dedicated decking showrooms, giving clients a hands-on experience with materials, finishes, and design possibilities. This combination of craftsmanship and education helped position LeBlanc Decks as a trusted authority in the outdoor construction industry.
As demand increased and the company’s reputation expanded, LeBlanc Decks achieved several significant milestones, including being named “Contractor of the Year” by Deckorators in 2022 and ranking among the top Deckorators suppliers nationwide. These achievements reflect not only the quality of the work but also the consistency of execution and commitment to industry-leading standards.
In 2022, due to labor challenges in Oregon, the company made a strategic relocation to Knoxville, Tennessee. This move allowed LeBlanc Decks to continue growing while bringing its advanced building systems, engineering practices, and sustainability-focused philosophy to a new and expanding market. Today, the company serves residential and commercial clients across Tennessee and surrounding regions, delivering premium outdoor structures built with the same discipline that defined its origins.
What truly defines LeBlanc Decks is not just where we are located or how long we have been in business—it is how we think about construction. Every project is approached as a long-term structural investment. We do not believe in temporary solutions or surface-level construction methods. Instead, we focus on systems that resist failure: engineered foundations, advanced framing techniques, moisture protection strategies, and high-performance composite materials that eliminate many of the weaknesses found in traditional wood-based construction.
We also believe that transparency and communication are just as important as craftsmanship. That is why every client is given access to a structured project system that tracks progress, documents decisions, and maintains full visibility throughout the entire build process. From initial consultation to final walkthrough, every stage is documented and shared so clients always know exactly what is happening on their project.
At LeBlanc Decks, we see ourselves as builders, engineers, and problem-solvers—not just installers. Our work is guided by a commitment to precision, accountability, and long-term thinking. We do not aim to be the largest deck builder in the industry; we aim to be one of the most reliable, most consistent, and most trusted.
Every deck we build is a reflection of that philosophy. It is not just a structure—it is a system designed to perform, endure, and remain structurally sound long after installation.
Our Mission – Built for Performance, Designed for Generations
The mission of LeBlanc Decks is to redefine what outdoor construction should look like when it is guided by engineering discipline, material intelligence, and long-term accountability. We exist to build outdoor living spaces that are not only visually appealing but structurally superior, environmentally responsible, and capable of performing for decades without compromise.
At the core of our mission is a simple but powerful belief: most outdoor structures fail not because of poor design intent, but because of shortcuts in execution. These shortcuts may seem minor at the time of construction, but over years of exposure to weather, moisture, and load stress, they become the root cause of structural movement, deterioration, and premature failure. Our mission is to eliminate those shortcuts entirely.
We achieve this by following a strict internal standard known as the LeBlanc Build Standard. This is not a marketing concept—it is a construction philosophy applied consistently across all applicable projects. It governs how we design foundations, how we frame structures, how we manage moisture, how we select materials, and how we finish every detail. It ensures that every project is built with consistency, regardless of size, complexity, or location.
Another key part of our mission is sustainability. We believe that responsible building practices are not optional—they are essential. That is why we prioritize wood-free composite decking systems that reduce environmental impact by eliminating the need for constant chemical treatments, stains, and sealants. These materials are designed to last longer, perform better, and reduce reliance on natural timber resources. We also work with manufacturers that utilize recycled materials and energy-efficient production processes, helping reduce landfill waste and environmental strain.
Our mission also extends into how we think about supply chains and transportation. Wherever possible, we choose North American manufacturing partners to reduce shipping distances, lower carbon emissions, and minimize packaging waste. These decisions may seem behind-the-scenes, but they are critical to reducing the overall environmental footprint of every project we build.
Equally important to our mission is accountability. We believe that a construction company should remain responsible for its work long after the project is completed. That is why LeBlanc Decks offers a lifetime craftsmanship warranty on all workmanship. This reflects our confidence in our processes and our commitment to standing behind every structure we build.
We also believe that clients deserve complete clarity throughout the construction process. Our mission includes creating a fully transparent project experience where communication is centralized, progress is documented daily, and decisions are clearly recorded. Every client receives access to a dedicated project portal that provides real-time updates, photos, documents, and communication history. This eliminates confusion, reduces miscommunication, and ensures that every project remains organized from start to finish.
Ultimately, our mission is not just about building decks—it is about raising the standard of outdoor construction. We aim to shift expectations in the industry so that durability, engineering precision, and long-term thinking become the norm rather than the exception.
We build every project with one expectation in mind: it must perform not just today, but for years and decades to come. That is what drives every decision we make, every system we design, and every structure we deliver.

Why Choose LeBlanc Decks – Built on Engineering, Accountability & Long-Term Performance
Choosing the right deck builder is not just about selecting a contractor—it is about choosing a company that will be responsible for the safety, durability, and long-term value of an outdoor structure that becomes part of your home. At LeBlanc Decks, we understand that decision carries weight, which is why every part of our process is designed to deliver clarity, confidence, and results that stand the test of time.
We are not a general construction company offering decks as an additional service. We are a dedicated, specialized deck-building firm that has refined every aspect of outdoor structure design and construction over decades of experience. Our approach is intentional, engineered, and consistent across every project, regardless of size or complexity.
Below are the key reasons why homeowners and commercial clients continue to choose LeBlanc Decks when quality, durability, and long-term performance truly matter.
Specialized Deck-Only Expertise
We focus exclusively on outdoor decking systems and related structures. This specialization allows us to develop deeper expertise in structural design, material performance, and long-term durability than general contractors who divide their attention across multiple trades. Every project benefits from years of focused experience in deck engineering, not generalized construction knowledge.
Engineered Construction Standards
Every structure we build follows a defined internal system known as the LeBlanc Build Standard. This is not a flexible guideline—it is a strict construction framework that governs how we design foundations, install framing, manage moisture, and execute finishing details. This ensures consistency across all projects and eliminates the variability that often leads to long-term structural issues.
We build with the assumption that every deck must perform decades after installation, which means we prioritize structural integrity, load distribution, and environmental resistance in every decision we make.
Advanced Foundation Systems
Unlike traditional deck builders who rely heavily on standard concrete footings, we use engineered mechanical foundation systems whenever site conditions allow. These include helical piles and ground screw systems, which provide immediate load-bearing capacity and long-term stability. This approach reduces settling, minimizes moisture-related issues, and creates a stronger structural base for the entire deck system.
High-Performance Framing Techniques
The framing of a deck determines its long-term behavior, and we treat it as one of the most critical elements of construction. We use advanced framing systems, including kiln-dried after treatment (KDAT) lumber and alternative structural materials, depending on project requirements. Our framing approach reduces movement, increases rigidity, and improves long-term structural alignment.
Wood-Free Composite Decking Systems
We specialize in wood-free composite decking systems designed to eliminate the most common causes of deck deterioration. These materials resist moisture absorption, prevent rot, reduce warping, and maintain dimensional stability over time. The result is a surface that remains visually consistent and structurally reliable with significantly lower maintenance requirements compared to traditional wood decking.
Precision Fit and Architectural Finish
We believe that performance must be matched by visual quality. Every deck we build is designed with attention to detail, including clean board layouts, hidden fastening systems, and carefully executed finishing elements. Where face fastening is required, we use color-matched plugs for a seamless appearance. Fascia boards, stair systems, and trim details are fully integrated to create a refined architectural finish.
Lifetime Craftsmanship Warranty
We stand behind our work with a lifetime craftsmanship warranty on all installation work. This reflects our confidence in the systems we use, the standards we follow, and the quality control we apply to every project. Our responsibility does not end when construction is complete—it continues for the life of the structure.
Full Project Transparency
We believe clients should never be left guessing about the progress of their project. That is why every LeBlanc Decks client receives access to a dedicated project portal that provides full visibility from start to finish. This includes daily progress updates, photos, schedules, documents, and communication logs, all in one centralized system. Transparency is not an added feature—it is part of our standard process.
Structured, Predictable Process
We follow a clearly defined construction process that removes uncertainty and ensures smooth project execution. From initial consultation and design planning to permitting, scheduling, construction, and final walkthrough, every step is organized and documented. This structured approach reduces delays, prevents miscommunication, and ensures consistent results.
Sustainability-Driven Building Philosophy
Our work is guided by a commitment to responsible construction practices. We prioritize materials and systems that reduce environmental impact, including recycled composite materials, reduced reliance on chemical treatments, and partnerships with North American manufacturers. These choices help lower transportation emissions, reduce waste, and support more sustainable building practices.
Consistency Across Every Project
Whether a project is large or small, residential or commercial, our standards do not change. Every deck is built using the same engineering principles, material quality expectations, and finishing requirements. This consistency ensures that every client receives the same level of performance and craftsmanship, regardless of project scale.
Client-Focused Communication System
We eliminate confusion and communication gaps by centralizing all project communication in one system. Clients receive organized updates, clear documentation, and direct access to project information at all times. This reduces stress, improves coordination, and ensures that decisions are always documented and accessible.
Built for Long-Term Value
At LeBlanc Decks, we do not build for temporary appeal—we build for long-term value. Every structural decision, material selection, and design choice is made with durability and performance in mind. The goal is simple: create outdoor spaces that continue to perform, age gracefully, and add value to the property for decades.
A Commitment to Doing It Right
Ultimately, what sets LeBlanc Decks apart is not just what we build, but how we think about building. We believe that outdoor construction should never rely on shortcuts, assumptions, or temporary fixes. Instead, it should be guided by engineering discipline, material intelligence, and a commitment to accountability.
That is why clients choose us—not because we are the fastest option, but because we are the most reliable one for building outdoor structures that are meant to last.
