At Cedarbrook Outdoor Design/Build, we believe your backyard should be more than square footage, it should be a place where life happens. For over 20 years, we’ve been designing and building exceptional outdoor living environments that bring families together, create lasting memories, and instill genuine pride in the places people call home.
Our mission is to offer a wide range of well-designed, functional outdoor living environments that allow homeowners to enjoy time with family and friends in the comfort of their own homes.
Cedarbrook’s vision is to create functional environments for homeowners that instill pride while allowing them to truly relax and find enjoyment in their own home — as the dynamics of homelife evolve and change.
What started as a passion for thoughtful design and quality construction has grown into one of the region’s most recognized outdoor living companies. Over 20 years, we’ve built hundreds of custom decks, pergolas, patios, porches, and complete outdoor spaces, each one tailored to the family that will live in it.
Our longevity isn’t just a number. It’s a reflection of the trust homeowners place in us, the relationships we’ve built, and the standards we refuse to compromise on. Every project we take on carries the same commitment it always has: do the work right, stand behind it completely, and leave the homeowner with something they’re proud of.
Recognition from the industry’s most respected organizations reflects what our clients experience firsthand — a company that holds itself to an exceptional standard.
Recognized by the North American Deck and Railing Association (NADRA) for excellence in the outdoor living industry.
Named Deck Specialist of the Year by Yellawood, one of the most respected names in outdoor building materials. This honor recognizes outstanding craftsmanship, design expertise, and dedication to the craft.
Each year since 1986, Remodeling Magazine has inducted just 50 remodeling companies nationwide into the Big50. This recognizes firms that set exceptionally high standards for professionalism, integrity, craftsmanship, and community impact. Since the program began, fewer than 2% of all remodeling businesses in the country have earned this distinction. Cedarbrook is proud to be among them.
Achieving Platinum Pro status with TimberTech reflects our deep product expertise and high volume of quality installations, placing us among a select group of contractors at the top tier of the TimberTech builder network.
Our NADRA certification in deck evaluation and inspection means we bring a trained, professional eye to every project, whether we built it or not. Homeowners can trust that their outdoor structure meets current safety and building standards.

When we say we build it to last, our warranty backs it up.
Cedarbrook was founded on a simple belief: that great outdoor spaces start with great design. Owner Mike Arneson Jr. brings a designer’s eye and a builder’s discipline to every project, with a deep specialization in outdoor design that sets Cedarbrook’s work apart from the standard contractor.
When Mike isn’t building outdoor spaces for others, you’ll find him enjoying his own. An avid outdoorsman and family man, Mike spends his time golfing, fishing, hunting, hiking, and playing pickleball — and traveling whenever the opportunity allows. That genuine love for outdoor living isn’t just a hobby. It informs every decision made at Cedarbrook, from the materials we specify to the way we think about how a space will actually be used.
Our team has spent years helping Maryland homeowners create outdoor spaces they’re proud of. Every person here is committed to the quality and craftsmanship Cedarbrook is known for.

Supporting the communities where we live and work matters to us. We have sponsored the Three Rangers Foundation Golf Tournament for three years running, and we back a wide range of local organizations including Center Stage Performing Arts Academy, MAYAA Baseball, Mt. Airy Net, Mount Airy Fire Department, the local VFW Post, Libertytown Fire Department, Mount Airy Christian Academy Robotics Club, the Give Back Deer Crossing annual fun run, Kiwanis Club, and Linganore High School Athletics.
We’re not a volume builder. We’re a team that takes the time to understand how you live, what you value, and what your family needs from your outdoor space, then designs and builds something that delivers on all of it. That approach has earned us long-term relationships with clients, referrals that span generations, and a reputation we work hard to protect every single day.
Whether you’re starting with a clear vision or a blank backyard, we’re ready to help you create an outdoor space that exceeds expectations; and lasts for years to come. Call Cedarbrook Outdoor Design/Build at (301) 703-8728 to connect with our experts and take the first step toward the outdoor spaces you have been envisioning. We are located at 2303 Back Acre Cir, Mt. Airy, MD 21771 and serve homeowners throughout the surrounding Maryland region.
