Lawn care, mulching, top soil, hedge trimming, weeding, and more serving the communities of Stamford, New Canaan, Darien, Greenwich, and Norwalk. 5% lifetime discount on lawn cuts to those in the 06903 ZIP code Leedsland.com

"5 stars! Eric has been so responsive, professional, hard working and honest. We were looking for lawn mowing, weeding and mulching and Eric provided detailed quotes quickly...and his pricing was very competitive with other businesses. On work days Eric and Trey show up early and work non-stop until the job is done. The results look fantastic -- and they always make sure to clean up. Most importantly, Eric is honest -- when a job was finished faster than expected and less material was used he discounted the bill accordingly. We have been so pleased with Leeds we are going to also use them for fertilizing and weed control going forward."

"I recently hired Sanchez Brothers to handle trimming, shrub removal, and a full clean-up of my backyard, and I couldn’t be more pleased with the results. From the very beginning, their customer service stood out, they were quick to respond, professional in their communication, and made sure they fully understood what I wanted done. The team arrived on time, well-prepared, and got right to work. They were incredibly efficient and hardworking, carefully trimming and removing overgrown shrubs while keeping the surrounding areas neat and undisturbed. I appreciated how they paid attention to detail and followed through on every request I made. The clean-up afterward was just as impressive."
