We engaged CS for invisible grilles installation at both outdoor balconies and are extremely pleased with the customer service and quality work from start to finish. They assisted in removing our old manual blinds and patched up the holes well. The grilles were professionally and intricately installed to precision. They took care to protect our indoor flooring and clean up the balconies well. The team, consisting of Imran, Rubel and Amin, has a pleasant attitude, and are professional and skilful at what they do! 🙂 Appreciate it so much, thank you!
