I'm so glad I found Carol & her company. She had excellent reviews & all were accurate. She transformed my typical Chicago backyard with a dog run into an awesome patio with a retainer/seating wall. It definitely opened up my yard & makes me want to stay out there all day. It was great working with her & I highly recommend her. Her crew were skilled, courteous & cleaned up my property each day they worked. I only wish my project was larger for her so I could show off more of her design talents.Read More

Our backyard feels like heaven on earth! Carol really listened to how we like to enjoy our space and transformed our backyard. The new plants, native to the area, are thriving. We installed a Trex deck where we grill and added a patio. Unsure how to coordinate our new look with a tired side of a shared fence, Carol recommended a low priced DIY solution that we love. We highly recommend Carol and her team!Read More

We are incredibly happy with our backyard landscaping project! Carol and her team were great to work with, highly skilled, creative, thoughtful, and always kept the work site clean and tidy. The end result is beautiful and just what we hoped for! We highly recommend Heffernan Landscaping!Read More

We hired Carol based on photos of her work and her solid reputation. It turned out to be a great decision because she was excellent to work with and her vision went well beyond the run-of-the-mill landscaping approach. Her art background comes through in her designs. She came up with a unique, tasteful, and beautiful design that has really enhanced the curb appeal and value of our property. Throughout the process, from design to implementation, she was professional, friendly, responsive, knowledgable, and a very timely communicator. Her crew was equally fantastic. We saw quickly that they were skilled, and that we could count on them to do the project right. We will be soon utilizing Carol to landscape and enhance our backyard.Read More

Carol and her team were wonderful! We began working the project, an initial design, with Carol in April. By early May we had a finalized plan and knew the timeline and schedule for construction. The team arrived promptly every day around 8:30am, and stayed until after 5 some days...they worked so hard even during the hottest days. Once construction started, it took a week to complete. We could not love it more, our vision of desert in Chicago happened! We love it!Read More
