About Andrea

Andrea is a dedicated real estate professional with a proven and impressive track record. Having entered the business in 2003, Andrea was quickly named Rookie of the Year and became one of the #1 producing agents in the Darien/Rowayton market. She has continued her success as a top producing agent throughout her career with distinguishing awards. Her boundless energy and enthusiasm, market knowledge and commitment to customer service speak volumes.
Andrea attributes her success to a combination of professional experiences from entrepreneurial, to traditional financial services sales, and lifestyle and destination marketing. Couple this with over 30 years as a resident of Darien, New Canaan and Rowayton and she is well equipped to handle the listing or buying needs of consumers - from condos to waterfront residences, from first-time buyers to empty nesters. Her expertise includes the sales of lots and land, new construction properties and charming antiques. She covers coastal Connecticut, including Darien, Rowayton, New Canaan, Norwalk, Westport, Southport, Fairfield and Greenwich, with her niche revolving around waterfront properties.
Andrea enjoys sailing (Noroton Yacht Club member), skiing, biking, kayaking (she built her own), cooking, traveling around the world, reading and photography. Andrea is dedicated to excellent customer service, foresight and vision and is committed to understanding a client's needs, lifestyle, community interests and financial goals. She'll go the extra mile, from back to back open house weekends to strategic meetings to helping clients fight (with great success) their tax assessments.

★★★★★"We had the pleasure of working with Andrea Kostanecki to purchase our home at 21 Cherry Street in Darien, CT, and we couldn’t have asked for a better partner in the process. Andrea’s knowledge of the market, attention to detail, and commitment to our needs made the entire experience seamless. She guided us every step of the way, offering insightful advice and always having our best interests at heart. Above all, we knew we could trust her completely, which made a world of difference in such an important decision. If you’re looking for a dedicated, professional, and trustworthy realtor, Andrea is the one!"
★★★★★
"Andrea is experienced, knowledgeable and professional. She walked me through every step of the process and was just a delight to work with. I Highly recommend her"
★★★★★
"Dear Andrea, Huge thank you from me and the family for getting this house sold so quickly! What an enormous relief to be out from under this liability. You did a spectacular job and I am so very grateful for your terrific help. With many thanks again - and beyond!"
★★★★★
"We worked with Andrea to find a home in Rowayton and she was wonderful. She was incredibly proactive, attentive and thoughtful about the options she showed us, was mindful of our scheduling constraints - and ultimately found us our dream home! We are so appreciative of her support and would highly recommend her to someone looking for a driven and committed agent."
★★★★★
"We had owned our house in Rowayton for almost 20 years when we listed it with Andrea. For years I kept an eye on sales in the neighborhood looking for agents who showed a knack for marketing homes energetically and a track record of success. Andrea was on a very short list that met my criteria. Working with her closely just reinforced my opinion. Everything about our sale went as smoothly as we could have hoped."
★★★★★
"Andrea handled our sale with driven, never giving up, professionalism. What was impressive was her energy connecting people in the area and figuring out who could help her make the sale, i.e. this person knows that person. Andrea totally knows the community. Andrea is extremely hard-working, always has a smile and just does not give up working to sell your house. And when was the last time your broker cooked up a lobster dinner for you? We highly recommend Andrea! Cheers!"
★★★★★
"Andrea is like the Mayor of Fairfield County! Her colossal contact list helps her attract buyers as well as sellers. She knows the market (she grew up here on the water). She prizes relationships with her clients (they invite her to dinner and their weddings!) and with other realtors (they have her back!). She is a trusted local figure; savvy about the market; curious and clever about what makes the market move; perpetually seeking new ways to get houses sold. You'll begin as a client; you'll end up as her friend!"
★★★★★
"At a time when the bottom had fallen out of the real estate market, I needed to sell my home and relocate. Andrea came to my rescue with a keen eye and dedication to helping me through the long and difficult process. She was sharp and well aware of how to negotiate the rough waters of the time and not only found me a buyer but helped me keep my sanity! Kudos to a great real estate professional."
