Years of Local Experience
and a Reputation for Quality Results
Founded in 1999, Growing Seasons Landscaping has earned a solid reputation for delivering high-quality commercial landscaping results. Over the past 25 years, we have created hundreds of true partnerships with local businesses and organizations who depend on us for necessary landscaping services, including year-round landscape maintenance, snow and ice management, and landscape installation projects. We also do environmental projects for industrial-type properties, such as site reclamation, erosion control, and slope stabilization. No matter whose property we are servicing, our focus is on meeting and exceeding our clients' expectations.
Our team is passionate about what we do. As professional commercial landscape contractors, we are well-trained and safety-oriented. As the largest privately-owned commercial landscaping company in the Pittsburgh, Pennsylvania, area, we can handle a wide variety of projects, including large and complex projects that other companies won't do. Because we have many employees working on our crews, we can prioritize your project and get it done on time, so you don't have to wait for results. In fact, we pride ourselves on hitting our deadlines every time.
When you hire GSL, you are dealing with a local company with local owners. You will have direct access to our managers and team, and we will provide you with a dedicated account manager as a primary contact who can address your needs and questions.
We have a 24 business hour call back promise, which is far superior to corporate landscaping companies that make you wade through a lot of corporate answering machines before you can talk to a real person. At GSL, if you have issues on a property that we manage, we will handle the issues on the same day when possible, or we will provide a timeline that tells you when it will be done.
When you partner with us, you are not just a number. We are here to care for you and your property.
