About us

We are a family company that works with passion in the latest trends in landscapes and we strive to exceed the expectations of our customers.

Pittsburgh Stone and Waterscapes, LLC was founded originally under the name, Garden Graphics Landscaping, in 1982 by Bob Blunkosky. The original services offered included: Landscape installation, sprinkler systems, and lawn installation along with landscape and lawn maintenance. Jeff Blunkosky, Bob’s son, was involved in maintaining the plant nursery and shop grounds at the age of 12 along with working summers and weekends on site, ultimately working full time for the company in 1994. In 2002, Garden Graphics changed its name to Pittsburgh Stone and Waterscapes, LLC. The name change came about due to the company’s expansion of its previous services to now include 3D design, low voltage lighting, drainage solutions, excavation and especially a large role in the hardscape industry. They added services that included the use of pavers, boulders, retaining walls, ponds, waterfalls, outdoor kitchens, fireplaces, pools, and carpentry components for residential clients creating our signature service of the Outdoor Living Space.

By 2014, Pittsburgh Stone and Waterscapes maintained a yearly sales growth by 15% on average doing over two million dollars of installations in 2014. We have earned media recognition from National TV (HGTV), newspaper/magazine articles (Pittsburgh Post Gazette, Pittsburgh Tribune Review, House Tends, Lawn and Landscape, Total Landscape Magazine). We are two-time Unilock Award of Excellence Winners, and 2013 Pittsburgh Builders Association’s “Winner for Best Outdoor Living Space” .

Pittsburgh Stone and Waterscapes was founded and currently run as a family-owned business. We have maintained our core fundamentals focusing on operating a professional company, staying on the cutting edge of the newest landscape trends, and striving to exceed our customers’ expectations.

We take genuine interest by individuals passionate about their trade to create something special.

Robert Blunkosky

Founder and
Project Manager

Robert Blunkosky established the company, Garden Graphics Landscaping, in 1982. Prior to starting the business, Bob had been involved in the civil engineering field for 15 years. A background in design and drafting, along with further horticultural education, paved his way to having his own business. Never being content to sit behind a desk, this allowed him to work on projects from design to construction in the field. Over the next 30 years, the family-owned business expanded into all facets of outdoor projects to meet the demands of its customer base. Garden Graphics became Pittsburgh Stone and Waterscapes to reflect this change. The business has steadily grown over the years and is proud of the projects it has completed. The idea of creating outdoor creations that our clients would enjoy year after year has been most rewarding for Bob. In 2012, ownership of the company was turned over to Bob’s son, Jeff Blunkosky, which allows Bob to be semi-retired, but he is still active as a project manager and a machine operator at times. When not managing, Bob is an avid off road bike rider and golfer.
