We had a fantastic experience with Cosco Landscape for the installation of patio pavers and a white vinyl fence for our back yard. We had no prior history with this type of installation, so we made sure to conduct an extensive search and vetting of local contractors (Watertown/Newton/Waltham-based) over several weeks to get their competing assessment and opinions on the size/scope of the project. Cosco came out on top on just about every metric, including responsiveness, ease of conversation & discussion about our needs, and most notably price. When we made the final decision to move forward, Dom notified us there happened to be an earlier opening for the work and mobilized almost immediately to start on our project, several weeks ahead of his (and all other contractors') initial projections on start date. The Cosco crew that showed up was extremely professional and efficient, and completed the entire project in less than one week. We were impressed by the both the turnaround time and overall quality of the work, and are very happy with our decision to go with Cosco. The photo below is from about one month after the job was completed, including the grass that was re-seeded now fully grown in.

I would not recommend this company for landscape maintenance if you have anything beyond a basic lawn and shrubs. While working on my neighbor’s yard, two employees entered my backyard without my permission, mowed my grass, and pulled out several ~2-foot-tall plants and wildflower seedlings from my mulched garden beds. These were intentionally planted and maintained, not weeds. The whole thing was captured on my backyard security camera. I contacted the company and the manager said he would look into it and get back to me, but I never received a follow-up. (Edit: after a few weeks, I posted this review, and then I was offered replacement plants or store credits). It is disappointing that a landscaping company could not distinguish intentional plantings from weeds.

I'm very impressed with the work Cosco Landscape did on our property. From start to finish, the team was professional and timely. They understood our unique situation living in a flood zone and installed AquaBricks as part of the design—a thoughtful solution that shows they really care about their work. The AquaBricks were laid in a beautiful, artistic, and eye-catching pattern that really enhances the overall aesthetic of our property. The driveway was properly leveled, and the overall design is unique and looks fantastic. What impressed me most was that all of this quality work came at a reasonable cost. We got real value for our investment. This work was completed in 2022, and I can confidently say it has held up perfectly through several New England winters. The durability has been exceptional. Since we share the driveway with neighbors, I'm happy to report that they are all thoroughly satisfied with the results as well. It's been a real asset to our whole property. If you're looking for a reliable, skilled landscaping company, I highly recommend Cosco Landscape. They delivered exactly what we needed and more.

Cosco Landscape just did an amazing job at my house replacing an old chain link fence with a beautiful retaining wall. Part of the job was making sure I had a flat yard when work was done and they did a great job. The land sloped quite a bit on one side but they built the wall exactly as needed and then filled in the yard. The crew was awesome. They cleaned up each day and all debris was removed at the end of the job. Great value for a great job. Highly recommend them and would definitely use them again for any job - big or small.

Such an awesome experience! Dominic was such a pleasure to work with the whole way through. His crew is super friendly and very hard working. The level of thought and detail that went into these projects is amazing. I don't think the prices could have been more fair and the work could not have been better. Thanks for transforming our home!
