I hired Darwin to pull some monster weeds in my yard after being ghosted several times by someone else. He showed up right on time the day after I contacted him. He worked non-stop for the 3 hours we agreed upon, even when it started to rain. He cleared all the weeds, and took them away. I will definitely hire him again!

Details: Residential • Small (less than 1,000 sq ft) • Over a month ago • No, I prefer no herbicides to be used • No, I don't need to be there • Only one time

We hired Three Rivers to help selectively pull weeds on our backyard hillside. Darwin submitted a competitive quote & we were duly impressed by his hard work, professionalism & commitment to finishing before our big party. He also communicated well & was punctual. Great job cleaning up, too. We will definitely use him for future work!

Details: Residential • Medium (1,000 - 5,000 sq ft) • Over a month ago • No, I prefer no herbicides to be used • No, I don't need to be there • I'm flexible

Three Rivers Exterior Solutions was wonderful to work with! They were quick to respond and schedule the work. The finished project, clearing a large area of weeds/unwanted bushes, was completed in a short amount of time and exceeded our expectations. Highly recommend hiring these pros!

I recently hired Darwin for mulching and edging, and I couldn’t be more impressed with the results. The attention to detail really stood out—everything looks clean, sharp, and professionally done. It’s clear he takes pride in his work and puts in the extra effort to make sure everything is just right. His dedication and strong work ethic were evident from start to finish. He worked efficiently without cutting corners and made sure the job was completed to a high standard. On top of that, the pricing was very fair for the quality of work provided, making it an excellent value for the money. I would highly recommend his services to anyone looking for reliable, hardworking, and skilled landscaping work.

Details: Residential • No, I will need the professional to provide the mulch • Small (less than 500 sq ft) • No, I will need the professional to prep the area for me • I applied mulch to this area over a year ago

Project was extensive. Tree, hedges, bushes, and ground were covered with morning glory weeds. All the greenery was badly in need of trimming. One bush even had a tree growing into it. Darwin also did work on the side of the house and in the back. He, along with another worker, worked all day to get the job done to my satisfaction. I was very pleased with the quality of his work. His time spent evaluating the work and communication exceeded my expectations. Communication continued to be very good with Darwin, both during and after the job. I highly recommend this company and have requested they cut my grass and weed the bank of my home every two week to keep it looking good.

Details: Residential • Small (less than 1,000 sq ft) • 3-4 weeks ago • Pro's recommendation • No, I don't need to be there • I'm flexible
