The company lists Greenwich among the towns it serves and says it has been in business for 15 years. In a 2025 review, a customer said Jader Sandy's team installed windows in living room and family room mahogany doors, a master bedroom, a basement, a garage and a bathroom, and said the prior windows were old with broken seals. A 2025 reviewer wrote that the salesman was also the installer, and said the new windows made a noticeable difference in the home's energy efficiency. In a 2023 review, a customer described a quote to replace 30 windows and a sliding door, and said the crew showed up on time every morning and left the house clean each evening. A 2024 customer with a small job said the company responded quickly, arrived on time for the estimate and stayed in touch during a special order, and that the install crew put down padding for their ladder and cleaned up. In a 2023 review, a customer said Jay and his installers covered all the furniture and cleaned what was needed when they left. A 2022 customer said Jader came right over and removed a window so a large couch could be taken out of the home, and said they later measured, ordered and installed a screen.
