  I can’t recommend Koen Landscape Group enough! They built a retaining wall for our property, and the quality exceeded our expectations. The wall is solid, looks beautiful, and completely transformed the appearance of our yard. They paid attention to every detail and made sure everything was done the right way. They also provide our weekly lawn maintenance, and they have been incredibly reliable. Our lawn always looks freshly cut, clean, and professionally maintained. They show up when they say they will, edge everything neatly, and leave the property looking spotless after every visit. They took the time to answer our questions, kept us informed throughout the project, and genuinely cared about making sure we were happy with the results. I highly recommend Koen Landscape Group. We’ll definitely continue using them for future landscaping projects!

  DO NOT DO BUSINESS WITH THIS MAN!! We hired Brett to put in a retaining wall and patio in our backyard on September of 2024. It took Brett 2 or 3 attempts at building the retaining wall, having to tear it all down and start again. No big deal, mistakes happen. The issue is, he “completes” the job (in quotations because he didn’t actually fully finish the job per his own admission via text but the bulk of the work was completed). Brett informs me of issues he had installing, assuring he’d come back to fix everything ASAP. The retaining wall blocks began to separate within months. Brett never came back to fix the retaining wall and we now have an uneven patio dirt seeping through the blocks. It was way back in March 17th, 2025 that he specifically said “it will be fixed no cost to you!!”. It’s now a full YEAR AND 3 MONTHS LATER and I still haven’t had anything done to remedy his shoddy work. He now has blocked my phone number too. To make matters worse, we’ve discovered Brett glued the retaining wall blocks together which drastically increases the cost to hire someone else to fix his work. Brett hadn’t responded to me in any form since since May 20th, 2025. I guess we’ll have to go to court. STAY AWAY FROM THIS FRAUD

  This company built a retaining wall and patio at our home, and the retaining wall started showing signs of failure within the first year. The photos speak for themselves: blocks separating, large gaps opening up throughout the wall, soil washing through the joints, and visible movement in the structure. When I brought the issues to Brett's attention, he admitted in writing that there was a problem and repeatedly assured me that he would fix it at no cost. He acknowledged that dirt passing through the wall was an issue that needed to be addressed and repeatedly promised to return and make it right. What followed was months of excuses, missed commitments, and broken promises. I have text messages spanning months where Brett said he would stop by, evaluate the wall, provide a timeline, and complete the repairs. He repeatedly apologized for delays and assured us he had "zero intention" of leaving the project unfinished. He even told us, "I want to fix it the right way for you." None of that happened. Instead, we spent months chasing him for updates while he continuously pushed things off. Eventually, he stopped responding altogether. At this point, either our numbers have been blocked or we're simply being ignored. We recently had the wall evaluated by other contractors. The consensus was devastating: because of how the wall was constructed, including the use of adhesive where the wall should have been built as a proper retaining wall system, the repair may require complete demolition and reconstruction. We have received estimates approaching $30,000 to tear out and rebuild the retaining wall and patio correctly. The worst part isn't even the defective work. Problems can happen on any project. The worst part is that the owner admitted there was a problem, promised over and over again to fix it, and then disappeared. Fortunately, we have extensive documentation, including photographs and text messages showing the issues, his acknowledgments, and his repeated promises to return. If this company continues to ignore us, those records will likely become part of the next step in resolving this matter. Save yourself the stress, expense, and frustration. Hire someone else. And Brett, if you're willing to stand on your word and come back to fix this mess, I'd be happy to take the review down :)

  I contacted Koen Landscaping on a Tuesday mid spring with my lawn on the quite long side, and these guys provided a very fair estimate instantly, and were here working the next day. They have exceeded expectations (do a much better job at a lower price point than previous service), show up on time, and have great attention to detail. I recommend their services highly.

  We hired Koen Landscaping for lawn service last year and we continue to be satisfied with the work they have done because the team has been professional and they have paid great attention to detail. Our yard has been consistently well-maintained throughout the summer and the fall. Their reliability and clear communication have been greatly appreciated because we have always been able to count on them to arrive on time, complete the work quickly and efficiently, and they have given us a heads-up if they are not able to work on our yard. It’s refreshing to work with a company that truly takes pride in what they do. We highly recommend Koen Landscaping to anyone looking for dependable, high-quality lawn care.
