Landscape Lighting Installation

Summers don't end at sunset. Driveways aren't only used during the day. Life often happens in later evening hours. Whether it's for safety, relaxing, or entertainment - outdoor lighting extends the usability of your spaces. From your beautiful trees, walkways, swimming pools, driveways, and beyond, trust our outdoor lighting expertise to put that finishing touch.

& 50 Years of Gary Duff Designs.

Where Our Craft Becomes Your Story

I have known Gary for over a decade. In these years he did numerous projects for us in three of our houses. From the smallest property (.3 acres) to the largest (2.5 Acres) he had the right ideas, design and the capability to deliver the highest quality that fit the project. All of the work he done for us brings praises from our neighbors, guests and family. Over the years we have worked with many different people and companies in all different trades, but none measure up to Gary’s standards. Gary is probably the most organized person we know and his team the most efficient. He was always available for us no matter how big or small or questions or requests were. I can highly recommend him any project small or large; he has proven over and over again that he delivers exceptional design and result in the shortest possible time.

Illuminate Your Outdoor Living

Today’s landscape lighting can completely transform the way you use your outdoor space. Whether you want to make a bold design statement or keep your light fixtures in a supporting role providing safety and ambience, you can choose from an incredible number of styles and techniques.

Outdoor lighting comes in a staggering array of shapes, sizes, colors, and textures. Anything from cubes to orbs, lanterns to floor lamps, you can add a touch of whimsy to any formal space simply for the sake of putting a smile on someone’s face.
