  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.
