Mark filled out all the permit paperwork for both the town and the state. Mark followed all the permit requirements, passing every inspection throughout the process. The result is a beautiful boardwalk and floating dock, and a restored boathouse and dock that had to be raised at least 3 feet maybe more. I'm extremely happy with the result, and Mark's honesty, reliability and fairness. The town was also impressed with his thorough care in following environmental rules and standards. I could not recommend Landmark Horticultural more strongly. **★★★★★ — Olga D, June 2019** > Mark has done a phenomenal job revamping 3 neglected acres on our property: > 1\) He repaved the driveway with gravel and added Belgian Stone edging, changed the entrance path into the house; > 2\) Fixed failing stone wall in visible areas and cleaned the area off overgrown bushes; > 3\) He put in a new fire pit and created a new blue stone backyard area; > 4\) He did new landscaping around the house (removed old dead plantings and installed new bushes, trees); > He is professional, on schedule, speaks English , always picks up his phone, fairly priced and flexible to the changing scope. > Below are before (red exterior house) and after (beige exterior house) pictures of Mark's work. **★★★★★ — 57 Mill, Sept. 2018** > Mark did a wonderful job painting our deck and replacing our railings with Trek railings. I would highly recommend his services. He completed the work on time and was great to work with on the project. **★★★★★ — Victoria Hollick, Sept. 2018** > Having had a few bad experiences with other companies, I was nervous about moving forward with the rebuild of my front steps and creating a bluestone patio. After hearing a few rave reviews about Mark, I decided to pull the trigger on the project with Landmark. > > Mark and his crew exceeded all expectations. Mark was fairly priced, he was professional and so easy to work with. They completed the project in a timely manor and he communicated extremely well with me. As we added on to the project, he was very clear with me regarding pricing changes and sent me updated invoices. The end result was beautiful and high quality stone work. My husband and I were so pleased! > > I highly recommend Landmark and plan to use them on future projects next spring. **★★★★★ — A W, July 2018** > Mark and his crew were excellent. Mark is a great communicator which is rare in a contractor. He is honest, reliable and very reasonably priced. We had him replace our retaining walls. The work his crew did was really beautiful-we are constantly getting comments from neighbors about how nice it looks. I highly recommend working with Mark! **★★★★★ — Mike, July 2018** > Great job, Great crew, Great contractor to work with. Hardworking crew. Cleaned up the worksite daily. During the installation of the deck, we added additional work to the initial project. **★★★★★ — Abigail Doheny, July 2018** > Landmark Horticultural Management took an architectural design for a pavilion and stone patio and made it into a beautiful outdoor living space that blends in naturally with my house in Chappaqua, NY. Mark and his crew do meticulous work, are professional and courteous. Mark even helped with all the permits and inspections. The overall price was fair and reasonable. I definitely got my money's worth. Even when I added and made changes Mark listened carefully and presented me with detailed proposals and executed only what I wanted. I enjoyed working with the company so much and was so satisfied with the finished product that I have asked them to return and do more projects. I highly recommend Landmark Horticultural. **★★★★★ — Kathleen Donovan, July 2018** > As Mark currently is working on our second outdoor project, I would like to recommend him without reservation for your next project. In the midst of dealing with some intense house issues and renovations, Mark was one of the easiest, friendliest, and most reliable professionals we dealt with, which in retrospect is the most important factor of a successful project. Mark set a schedule and stuck to it, provided updates every day, as well as asked questions and our preferences as needed. As an interior designer by trade, I really appreciate his eye for detail, as well as his inclination to collaborate and make the project better at every step. The end result is beautiful. He rebuilt an elevated retaining wall patio with bluestone and concrete architectural block, as well as built railings, a staircase, and fenced in our backyard. Mark picked up the slack when our less than competent landscape architect dropped the ball, and acted as liaison to the Town Building Department to smooth over issues that arose. We will be hiring him for all of our future outdoor projects - we have a ton in mind and are excited to start them knowing he will be at he helm. **★★★★★ — Jessica Paschkes, June 2017** > We have worked together on multiple projects beginning in Fall 2014 --from an extensive 2 level composite deck to custom planting design and beautiful stonework. Mark and his crew are hardworking, honest, detail oriented, and really do a superior job surpassing work we've seen from other contractors. Their prices are fair especially for this level of work. These are just some of the many reasons why we continue to work together. We HIGHLY recommend them to our friends and neighbors. **Comment from Landmark Horticultural Management:** > Thanks Jessica! It's always a pleasure working with you guys as well. **★★★★★ — Tanya Van Sant, June 2017** > Mark and his team are fantastic. Mark is so easy to communicate with. He also has a good sense of design. He and his team work fast and efficiently and within budget. We had them build us a new lake dock and a new deck attached to the dock. They did a beautiful job and we're thrilled with the results. **Comment from Landmark Horticultural Management:** > Thanks Tanya, It was a pleasure to work with you guys, hope you are enjoying your beautiful lakefront. **★★★★★ — Joy Alter, April 2017** > Landmark Horticultural Management, under Mark Rockower, was everything you would want in a landscape contractor: professional, reliable, on-time, and artistic! Everything Mark promised was provided, from time frame to clean up. And the ultimate pay-off was a beautifully designed patio that blends seamlessly into our existing natural settting. **★★★★★ — Gianluca Santelli, March 2017** > I contacted Landmark via a referral to demo and rebuild a deck that a previous contractor did not build properly, as well as add a large, blue stone patio. They were exactly as described - professional, thorough, high quality, and extremely knowledgeable. We're very happy with the results of the project and after 2 years, it looks as good as the day it was completed. I recommend Landmark to anyone looking for a professional and honest company and plan to use them on future projects. ## Selected projects - [Nature Boardwalk](https://www.houzz.com/hznb/projects/nature-boardwalk-pj-vj~6055431) - Location: Not specified - Photos: 4 - Description: 250' long raised walkway through wetlands to lakehouse and dock - [Lakehouse](https://www.houzz.com/hznb/projects/lakehouse-pj-vj~6055436) - Location: Putnam Valley, NY - Photos: 13 - Description: This was a historic lakehouse that had been submerged for many years. We were contracted to raise it and restore it. We drove wooden timbers into the lake bed, and then built and interior framework not connected to the lakehouse. Separately a temporary bracing frame was installed on the lakehouse and this was used to lift the structure, with hydraulic jacks, sliding up the interior frame like a sleeve until the proper height was reached, several inches at a time. Once we lifted it to the new hei… - [June 2017 \| Newly Completed Projects](https://www.houzz.com/hznb/projects/june-2017-newly-completed-projects-pj-vj~2553154) - Location: Chappaqua, NY - Photos: 13 - [City Garden, Upper West Side NYC](https://www.houzz.com/hznb/projects/city-garden-upper-west-side-nyc-pj-vj~2062615) - Location: New York, NY - Photos: 3 - [Mosaic Patio with Water Feature](https://www.houzz.com/hznb/projects/mosaic-patio-with-water-feature-pj-vj~2158405) - Location: Armonk, NY - Photos: 8 - [Assorted Plantings](https://www.houzz.com/hznb/projects/assorted-plantings-pj-vj~2160939) - Location: Chappaqua, NY - Photos: 9 - [Magnificent Mahogany](https://www.houzz.com/hznb/projects/magnificent-mahogany-pj-vj~2050022) - Location: New Castle, NY - Photos: 4 - [Mosaic Bluestone Patio](https://www.houzz.com/hznb/projects/mosaic-bluestone-patio-pj-vj~2047585) - Location: Armonk, NY - Photos: 5 - [Gnome House](https://www.houzz.com/hznb/projects/gnome-house-pj-vj~4052654) - Location: Carmel Hamlet, NY - Photos: 3 - [Fireplace Veneer & Mantle](https://www.houzz.com/hznb/projects/fireplace-veneer-and-mantle-pj-vj~5510878) - Location: Chappaqua, NY - Photos: 7 - Description: Renovation of an existing fireplace. During the demolition of an outdated marble veneer, we discovered original brick behind 70's paneling. The client decided painted brisk was better than paneling. Unable to remove the original paint on the brick, we applied a faux white wash effect using red and brown base paint and white chalk paint. The main focus of the project is an antique barn wood mantle. - [Floating Docks](https://www.houzz.com/hznb/projects/floating-docks-pj-vj~2050493) - Location: Carmel, NY - Photos: 8 - [Hillside nook Patio](https://www.houzz.com/hznb/projects/hillside-nook-patio-pj-vj~2047623) - Location: New Castle, NY - Photos: 5 - Description: A small cozy bluestone patio, mid-way down a long flight of steps.

Who is the manufacturer? A: hiya, sorry i missed this. That's real brick, set in cement on a concrete slab. I don't know the manufacturer, but they are common brick. **Q: Kayak launch** *(in Photo Questions)* I need one of these. What is the distances between the two sides don't the angle? Thank you A: HI There, the bottom distance is about 6" on the inside, with the angle being about 35 degrees. I made it on the fly out of a ripped down 2 X 8 and some scrap 2 X 4's so I don't recall the exact specs. It's weighted on the bottom with a large stone from the lake bed. **Q: I'm still growing stuff outdoors** *(in Vegetable Gardening)* It is 66 degrees, and tomorrow is supposed to be 75. My broccoli has started seeding. They look and act like broccoli, not collards. I harvested collards for the first time. Can anybody tell me if collards can be harvested like Leaf Lettuce in a 'cut and come again" fashion? A: we harvested spinach today. Yup, broke them out of the hardpacked snow and they look fine We took all the carrots and turnips last week before the snow. The collards we took last week as well. Here in the north they become much sweeter after a couple of hard frosts, same with parsnips. Collards we generally just cut em up and toss them in a cast iron skillet with onions and turnips, ginger, nutmeg, garlic, salt and pepper.... yum! --- *Source: Houzz professional profile.
