At Ultimate Services, our wealth of knowledge and commitment to customer service have made us an indispensable resource for some of New York and Connecticut's most selective residential and corporate clients for more than four decades. in 1971, while still in high school, John G. Chiarella, Jr. founded Ultimate Services with just one employee, a push lawn mower, and a handful of clients. From day one, providing outstanding customer service was his top priority. He mowed lawns, washed windows and did odd jobs with pride for area doctors, lawyers, and business professionals. Wishing to grow, John knew he could not expand his services without first increasing his knowledge. The University of Connecticut's Horticulture program was his answer. ### Services Provided - Landscape Construction - Hardscaping - Landscape Maintenance - Garden Design - Patio Construction - Paver Installation - Retaining Wall Construction - Pool Landscaping - Outdoor Kitchen Construction - Masonry - Outdoor Fireplace Construction - Drought Tolerant Landscaping - Artificial Grass Installation - Planting - Sod Installation - Tree Planting - Custom Putting Greens - Trellis Construction - Land Leveling & Grading - Lawn Care - Mulching - Site Preparation - Edible Gardens - Lawn Mowing - Tree Pruning - Tree Removal - Hedge Trimming - Lawn Aeration - Brush Clearing - Lawn Treatment & Fertilization - Lawn Seeding - Stump Removal - Weed Control - In-Ground Trampolines - Stump Grinding - Wood Chipping - Ice Removal - Golf Greens ### Areas Served - Stamford - North Stamford - Norwalk - Greenwich - Branford - Guilford - Darien - New Canaan - Wilton - Madison - Old Saybrook - Cos Cob - Old Greenwich - Armonk - Bedford - Chappaqua - Harrison - Rye ## Business Details | Field | Value | | --- | --- | | Business Name | Ultimate Services Professional Grounds Management | | Address | 288 Valley Rd., Cos Cob, Connecticut 06807, United States | | Phone | (203) 879-4201 | | Website | http://www.ultimategrounds.com | | Followers on Houzz | 28 | **Social profiles:** - Facebook — https://www.facebook.com/Ultimate-Services-1661744197386126/info/?tab=page\_info - X (Twitter) — https://twitter.com/uspgm - LinkedIn — https://www.linkedin.com/company/ultimate-services-professional-grounds-management?trk=tyah&trkInfo= - Blog — https://www.instagram.com/ultimateservices/ ## Contact - **Houzz profile:** [Ultimate Services Professional Grounds Management](https://www.houzz.com/professionals/landscape-contractors/ultimate-services-professional-grounds-management-pfvwus-pf~93620985) - **Website:** http://www.ultimategrounds.com - **Phone:** (203) 879-4201 ## Credentials **Certifications & Awards** - Merit Award of Excellence from the National Association of Landscape Professionals **Affiliations** - [The New York Botanical Garden](https://www.houzz.com/professionals/schools-and-organizations/the-new-york-botanical-garden-pfvwus-pf~813697435) - [American Society of Landscape Architects](https://www.houzz.com/professionals/schools-and-organizations/american-society-of-landscape-architects-pfvwus-pf~2014062207) - [National Association of Landscape Professionals](https://www.houzz.com/professionals/schools-and-organizations/national-association-of-landscape-professionals-pfvwus-pf~1351514719) - [Better Business Bureau](https://www.houzz.com/professionals/schools-and-organizations/better-business-bureau-pfvwus-pf~1830530549) ## Reviews **Overall rating: 4.9 out of 5 — 7 reviews** ### All 7 reviews **★★★★ — hopchester, Jan. 2017** > We have worked with Ultimate Services for the past six years and they have been in charge of our lawn care, spring/fall clean ups and general garden needs. Their team is profession, courteous, and accommodating. During our recent construction project, we relied on Phil and Nelson for many complicated landscaping projects. They moved large established trees and boulders, designed and built a swale and created a lovely blue stone terrace. We could count on them to get the job done on time and on budget. **Comment from Ultimate Services Professional Grounds Management:** > Thank you so much for the kind words. It is truly a joy working with you both on projects and seeing the job through. We are so excited to get things going again in the spring, and collaborate with you on more great ideas. I look forward to seeing you as always. > Philip Schweiger **★★★★★ — J. Pastorek, Jan. 2017** > Katie and Susan designed beautiful landscaping that perfectly compliments our home. They are good listeners and incorporated our ideas into the design. We are very happy with the results. **★★★★★ — Emma Pilkington, Jan. 2017** > As an Interior Designer, I have a strong idea of how I want my property to look. The team at Ultimate Services provides excellent service all year long. With each year that Ultimate has taken care of my property, it has looked more beautiful. Ultimate Services is always there for emergency work as well. After Hurricane Sandy, John Chiarella was onsite almost immediately to check for damage. If there is a snow storm, John always calls to check in. With weekly visits from a dedicated horticulturalist, one can rest assured that their garden is very well maintained. Ultimate is more than a landscape company, they are like family. **★★★★★ — Charlotte Matitia, Jan. 2017** > We have been using Ultimate Services for the past two years to take care of our annual garden maintenance. No job is too small or too big for them. From spring to fall clean up, pruning, weekly mowing, feeding, seasonal planters etc…They are always available, accountable and quick to respond. They take the time to know their clients and provide a customized service. John and Susan are a pleasure to work with. I would highly recommend their services. **Comment from Ultimate Services Professional Grounds Management:** > Charlotte, It is such a pleasure working with you. We love helping your gardens come to life. Thank you for everything! Susan **★★★★★ — Paula McInerney, Jan. 2017** > I have tried several landscape companies before Ultimate Services. They are the Best! All The workers are courteous and professional and they do exactly what they say they are going to do when they say they are going to do it. I highly recommend them.I have used their services on two separate properties. **Comment from Ultimate Services Professional Grounds Management:** > Thank you so much Paula. It is a pleasure working with you and everyone else on the property. We are so excited for another great year! > -Philip Schweiger **★★★★★ — Mark Slotnick, Jan. 2017** > Very good service. A little pricier than other landscapers, but worth the cost. Have a horticulturist who oversees property. Very responsive and knowledgeable - pleasure to work with. **Comment from Ultimate Services Professional Grounds Management:** > Mark, So glad you see the value of our service, we love working with you. Sue **★★★★★ — Anna Jean Steele, Jan. 2017** > I cannot say enough great things about Ultimate services. I run a very large estate with complicated landscaping- and the plowing is very tricky as well being that we seem to have our own weather pattern and a very steep long driveway. Susan Fields in particular is an amazing manager. She accommodates our needs on a moments notice. This will be our 4th year in contract with them. I highly recommend their services! **Comment from Ultimate Services Professional Grounds Management:** > I am looking forward to another year with you too! Challenges are what we live for!
