“I had 3-4 variation orders, mainly because of coordination with estate management and other sub-con groups, but Alex of Sapphire Windows (SW), has shown me much maturity and patience to resolve. This is the second home, I have used SW. The first of 15 years ago, still stands comparable and handsome as the new ones now. Hardly any care given despite weather exposure. Truly a window, one only needs to fix once. I believe in keeping my lines strong and it will frame the entire apartment well . Excellent product, excellent service.”

“10 years ago, used Sapphire Windows (SW); was very pleased with their high quality products then. 10 years later, used SW again (after comparing with other competitors in the market) for new work. The quality of SW products remain high. The team's professionalism esp Ken and KC were superb. Ken was esp helpful, he took the effort to listen and truly understood my requirements. The end results exceeded my expectations based on his recommendations. Visitors to my home never fail to praise or comment on the new work done. I continue to recommend SW to my family and friends. Keep up the good work, Sapphire Windows!”

“The best sound proof windows in Singapore. The quality is amazing and the service is awesome as well. I would definitely recommend Sapphire Windows to anyone who’s in the midst of the renovation or changing any windows. Actually, I’m glad that we used them as we got exactly what we wanted and saved at least 15 percent compared to others outside. With the quality of service, Sapphire Windows should be charging more.
