Maureen B.

FANTASTIC! We could not be more pleased with Costco services. The price was very reasonable, and the results were beautiful. The crew was very friendly, hardworking and respectful of us and our neighbors, they cleaned up the property every night as not all companies do. Dominic arrived on time, really listened to our wishes and provided good feedback. We installed a patio and Dominic ensured it flowed beautifully with the garden area. He purchased the plants and bushes we wanted and guided us on the ideal spots for placement. Stone pavers installed professionally in one driveway. We have hired several contractors through the years, and he is the best we have had. We will definitely ask Dominic back for Fall and Spring Clean-up.

The grass in the backyard is growing after just one week and it looks great! The front yard looks good, too.

Description of Work
Domenic was very responsive in setting up a meeting, giving me an estimate and completing the work very quickly. I hired Cosco to remove a layer of dirt, rocks, and garbage in our backyard after the installation of water tanks in the ground ruined the yard. His team then hauled in loam, prepped the loam and installed seed with fertilizer. They also cut the grass in the front yard, too.

Thanks so much for giving us this glowing review! We appreciate it and we're happy to provide great service for our customers. Let us know if we can be of any future service.



Cosco's rates are low, but the work done too quickly and ineffectively. I have ground cover in my very small front yard and Cosco was supposed to rake and trim it and the hedges 2x month. It simply wasn't done - I noticed a candy wrapper in the ground cover and I left it there to be sure it was cleaned out the next visit. It wasn't, it was still there two months later and the ground cover was never trimmed - I finally pulled the candy wrapper out and raked the yard myself (I had company coming over) . I told Dominic and he claimed that they had been to my house numerous times and I said that if that were true, they were not doing a good job. I abandoned the 2x monthly appts and said I'd rather pay more for more extensive clean up. After two rounds of fall clean up, the front yard ground cover was still matted with leaves. I called again and said that I couldn't pay the bill until the leaves were actually raked and they never returned to finish the job. I refused to pay until the job was done right and Dominic's team never came back and then he sued me in small claims court. I have hired a new landscaper.

[Member Name Removed], We're sorry you weren't happy with the work. It seemed like we could never quite get on the same page despite our best efforts. Your property is a little unusual because there's not a lawn and it's harder to see our efforts and it's so easy for the wind to blow stuff into the bushes on the property in between visits... We wish you the best going forward and we're sorry the service didn't seem to quite meet your expectations. Kind regards, Cosco Landscaping

Domenic (owner) was amazing. I am a real estate agent and was listing a townhouse in the South End. It was very last minute and when I started calling around, I couldn't find anyone who could do the work. I understood the this was a very busy time for landscapers. When I called Domenic, he explained that they too were so busy, but he said that somehow he would make it work and he did. He was so responsive and nice to deal with and the work was great as well.

Dominic provided an estimate for removing damaged walkway surface between driveway and side entrance to the house. Recommended Ideal Pavers once the initial consultation was complete. After selecting desired style and layout, Dominic's team successfully removed damaged materials, leveled the area, re-directed a downspout, installed the new pavers, directing water flow to a new drain. A new Ideal concrete step was installed after the original step design proved to be insufficient. The Cosco installers were professional, timely, cleaned up afer each day, and used their expertise to make the best of some difficult situations during the job.

Great! They did exactly what we asked, quickly and cleanly. If they keep doing well and remaining responsive at a fair price, we'll keep using them as we get our yard ready!

Description of Work
This is the second time we've used Cosco for some lawn work. The first time, we had them remove some shrubs and a tree stump. This time, they removed our front yard sod and helped prep the soil so we can put in a garden next year. I like them because unlike other landscape contractors we've tried to use, they are responsive and actually do the work.

This company is SUPER. Really really good prices and prompt attention. We have had a small communication issue concerning the trimming of a few of our shrubs, but other than that they go above and beyond from a service perspective. We have a house that is a 2-unit condo, and have adopted Cosco as our primary lawn service vendor. We hope to use them in the winter for snow removal as well. Pleasant to deal with, easy to contact via email, and they do a great job. I love that they are local and care about their neighbors.

The biggest concern was the front brick pathway. It had warped so that ice pooled in spots and water didn't really drain through. They walked me through that all of the pathways were a problem but didn't try to upsell me on the paths that weren't yet buckling (driveway, side of house). They did an excellent job and it held up for the past winter. Because my sidewalk slopes toward the house rather than away, they also let me know that if/when the city gets around to fixing the sidewalks, I will likely need to fix the brick pathway again. I will definitely hire them again for that work. For the cobblestone border, we had a miscommunication about which edges I wanted done. It ended up being more than the original quote due to that, but that's completely understandable. It looks really nice. The one area I was less pleased was the plantings, but that is my fault. I was in a rush and didn't spend enough time communicating what I wanted and just had them pick the plants themselves. The dogwood tree has survived the winter and is about to bloom, so yay! Update in 2016: Held up well during the winter!

Jameson H.

I'll be honest - I've had a lot of contractors at my house in the past 6 months and Cosco was by far the worst. Not only did Domenic not show up when he was originally scheduled to, but he never even call to apologize / reschedule. He then just randomly showed up and was poking around the yard when I happened to run into him. As we're talking, he makes it clear he wanted to get out of there as fast as possible, and as I start to try to explain something about the job to him, I literally hear him mumble "oh my god..." Anyway - he also came back as the highest quote for what I'm sure would have been terrible quality work. Would highly recommend not using him

He was not responsive to our request for a simple repaving job… he wanted to pitch his more expensive redo. So we went with a different contractor.

He recommended we do more to the driveway than made financial sense.

Service Provider Response

We do our best to advise our customers like we would advise a family member. We don't think it was a good idea to do the bare minimum in your case and that you might be wasting money over the longhaul. We hope it worked out well with the other contractor and that you were happy with the service.

Short Form: Cosco Landscaping did fine masonry work, but only so-so fence work. Like many contractors, we had to push them on details they would have rather ignored. They added charges to the final bill without warning. When we disagreed with the charges, Domenic escalated to name calling and threats of property damage instead of listening to what we were saying. Longer form: There were many of the small frustrations and corrections that I expect in dealing with contractors, but they were generally resolved. Eg: The patio was first installed as larger than the size on the diagram. They kept not putting fence posts places where the fence was going to turn. They didn't put the requested pattern of brick on the patio. Most of these were resolved when pointed out. It felt like Domenic was not good at listening to the details we thought were important, and instead wanted to try to make the space roughly match what he thought we wanted, without asking when he was unsure what we wanted. The brickwork on the driveway is nice and was relatively quickly completed. There were delays in the fence install, and the final work was not done until October after starting in July. Then the final bills came. There were over $1k of extra charges, which hadn't been mentioned until the bill, for things that we felt were in the original contract. For example, one charge was $650 for cobblestone edging. Domenic argued that the contract said "plastic edging", but the contract said "edging". We had had discussions on edging both before and after signing the contract, including how we would want stone, and Domenic never said anything like "that will cost about $600 extra", or told us that he hadn't included that in the contract. Domenic's argument for why we should pay appeared to be that he had costs he didn't include in the contract so we should pay them. He didn't argue that he had told us about these costs and what they would be, or that he couldn't have anticipated them and included them in the contract. We felt this was extortionary behavior. I tried to express that we were surprised by these charges, had been under the impression this work was covered by the contract, and expected "extras" to have had their prices disclosed and discussed while the work was ongoing. Domenic reiterated that he had spent money so we should pay for it, then, while sounding progressively more angry, escalated to implying I was naive, calling me unreasonable and difficult to work with*, and threatening to come onto our property and rip out the work he had done. By the time he made this final threat, he was angry enough that we thought there was a real chance he meant it. We offered to pay half of the charges, even though we thought they were not reasonable, because we were clearly not convincing each other. Domenic refused this. He did not offer a counter solution. (He did agree to go so far as to drop $350 of the $1280 extra charges, and claimed that this was a fair compromise because there were four line items and he was dropping two of them.) In the end, we decided to pay his roughly $1k extra bill, because we were tired of fighting with him. *When asked, the only specifics he could cite for why I was difficult to work with were that I took "15 minutes" to make decisions, and that I didn't tell his crew they had the patio size wrong, ie, different than the written diagram, until after they had laid bricks.

It went very well. We had a crumbling decaying wood retaining wall (made of railroad ties) in the back yard, and a fence that was in bad shape - it was not a simple job to fix the fence, because it was on a slope with tree roots in the way. We asked Dominic to try to fix it inexpensively - and he did exactly that. We were very pleased with the work. The only (very minor) thing i would say is that sometimes they weren't the best communicators - as to when the job would get done. But they were very good, and i would definitely use them again. Also, we had the job priced by two other companies, and Cosco was the best price.

This is a very professional organization. All the people I had contact with were very good -- friendly, competent, responsive. The owner worked with me to develop a plan for the work, making suggestions but also he listened well and was responsive to my interests. He kept me posted on the progress. The work done was of very high quality, and I am very pleased with the outcome. The only thing I would say is that it took some time to get all done, but I was not really in a rush for completion and placed a higher priority on the quality of the work, which was great.

It was clear from the moment I first met him when he came to do the estimate that Dominic Cosco knew what he was talking about. And when his crew showed up to install the new lawn with their bobcat, trucks etc. they started right in with courteous professionalism to do an excellent job. There were four men in the crew - they graded the area, took away unwanted dirt and rocks, put down 2 truckloads of screened loam, rolled it out, put down several layers of seed and fertilizer. They also made recommendations about exactly where to put the landscape timbers and rocks along one side, and then they proceeded to install them. Then they did final grading, and were done in one day, and it really looked good. I would hire them again.

Installed a new lawn with landscape timbers and rock wall on one side. Lawn size was about 24' X 24'.

I can't say enough good things about Domenic and Cosco Landscaping. This is the 2nd time I've used them (previously they put in a retaining wall and repaved my driveway). Domenic in the field, and Deb in the office, make a winning team. They both respond promptly by phone or e-mail. I thought the prices were very fair and the work excellent. The workers were pleasant and extremely tidy. They put everything back where it was and swept everything clean. Thank you Cosco Landscaping for another great job!

For insurance purposes, we were required to remove a set (about six) of stone steps at the side of our house, and replace them with up-to-code steps. Because these steps are never seen or used, we were anxious to spend as little as possible. Dom came out within days of our requesting a quote, and quoted an extremely reasonable price for removing the steps (in a very narrow area) and replacing with block and slabs, and then removing the stone from the property. He had said that he'd be able to schedule it within four to six weeks, which would have been fine, but then one day he called to say a job had fallen through and could his crew come that day to start work (this was within about a week of our signing a contract). Work was finished in a about a day and a half. Notably, as the crew arrived, Dom made sure to introduce each person to my husband. We were very impressed with this! After the work was complete, Dom called, because he had found that there was nothing but sand under the bottom step (and very little of that), so he'd had to go buy additional supplies (for $150), and wanted to make sure that it was OK to invoice us for that. We of course said yes! We would gladly use Cosco Landscaping again if we ever have the need, and highly recommend them!

It is my pleasure to provide a review for Cosco Landscape Co who constructed a driveway/patio in our yard. They provided services in two fronts: 1. professional handling of difficult neighbors. 2. timely and quality workmanship. The workers arrived as scheduled, and when they arrived, we were faced with threatening people across the street to call the police and demanding a permit. Even though we did not need a permit, Jim and Dom decided to wait. It was Jim who showed utmost patience and professionalism that I rarely see among contractors. He kept quiet and consulted with me exclusively without getting involved with others. He also managed to calm and reassure me as he explained whom to contact for a permit. Jim and the crew came back three days later after the city inspector and zone department confirmed that there was no need for a permit for a private property on a private way. Jim and the crew began excavating, and again, they showed great restraint as the neighbors harassed about parking the truck in front of my house. The excavation was completed on the first day. On the second day, again they showed restraint, worked quietly paying attention to their work and finished in a few hours. On the third day, they laid the bricks and installed the border to complete the project. As they left, I paid the balance, following which, the receipt was provided promptly. The completion of this project owes to professionalism of Jim and the crew. They worked in an open communication with me throughout, consulted with me each day to the final touches, even to put up a 'no stopping' sign. My gratitude is to Jim and the crew who made this project simple, quick and satisfactory all around. My overall impression of Cosco is that they are well experienced and able to handle multiple aspects of their work, especially in understand their clients' needs as well as providing an open communication. Yes, I will use them again.

This was great home improvement experience for me. Dom Cosco responded to my phone call quickly and was able to meet with me within a few days. He listened to my plan and gave good advice for improvements and was able send me an estimate in a timely manner. I was always informed about the work plan for the day or week. Throughout the project it was clear that there was good communication between Dom , the office staff, the crew and me. I appreciated not having to repeat instructions or constantly clarifying the plan. Sometimes I'd phone Dom with a question and he would already know what I was talking about because the crew had sent him a photo. The crew was sensational. They worked hard and efficiently, even on the very hot days of summer. Everyone was respectful of my neighbors and me and always did what they said they would do. The crew was obviously a group of skilled workers who were well trained and took pride in the jobs they do. Their workmanship was superb, every detail of the masonry was perfect. They were able to maneuver a bulldozer and other heavy equipment in a fairly tight space without damaging the properties of my neighbors. They transformed an ugly driveway and an ugly,old and cracked concrete sidewalk to beautifully designed and paved ones with attractive pavers. I no longer feel as if I'll trip on the the sidewalk. And, the new paved path leading from my driveway to the back door has made coming and going much easier. The lawn and garden were well designed and carefully planted. The crew even returned afterward for the first mowing of the lawn! Their kindness in sanding and painting the wrought iron banister on my front steps did not go unnoticed. I'm happy to say that my homely yard has been converted to a beautiful one and fits in better in my neighborhood. I'm very pleased with all aspects of the the job done by Cosco Landscaping and feel as if I received very good value for the cost. I would hire them again in a heartbeat.

The guy was excellent. They have been phenomenal and I would rate them highly. I had some medical conditions and they were willing to work with me and nicely. They have excelled in everything. The owner was exceptional and did an excellent job. I would highly recommend them and I can’t think of better things about them. They have been wonderful always. They are honest and show up when they say they would and do the work they say they would and clean up afterwards. I have never had any problems.

Description of Work
I used Cosco Landscape Co for landscaping. I am using them now for one of my other house. They do lawn mowing, fall and spring clean up and cleaned up the debris that somebody knocked out. They also maintain everything for me from cutting the shrubs to making sure all weeds are pulled. I have had a house fire so we had to get some debris and cement moved so they helped me with that too.
