What Our Clients Are Saying

“I’d like to reach out to the team at Terrafirma to express what a great job you folks did with our landscape project this year. EVERY detail was addressed from modifying the design on the fly once work had started to offering new suggestions and ideas for the areas that are adjacent to the area being worked on. Dennie Peters & his crew did an amazing job and we are completely 150% satisfied with the work that was done! “

Steve P. - Grass Lake

“We had a wonderful experience using TERRAFIRMA on a major landscaping project. Everyone from the sales rep, project manager, site manager to the labor workers were professional, respectful and talented. Our project turned out just like we imagined. We highly recommend using TERRAFIRMA. It was worth the cost. We will definitely use them again if we decide to have any more work done. Great job!”
