“Recently had my toilet door installed and overall I’m quite satisfied with the outcome. I especially love that they offer a golden colour option, which was something I couldn’t really find from other vendors I enquired with. The material used feels good and sturdy, and the finished look matches my expectations well. Chloe was very accommodating and helpful throughout the process. Price-wise, it was comparable to the other vendors I checked with, so I felt it was reasonable for the quality provided. Recommended!”

What Singapore homeowners
say.
“We could not be happier with our new window blinds! From the very beginning, the whole experience was smooth and pleasant. A special shoutout to Chloe from the office. She was incredibly helpful, responsive, and patient throughout the process. We had a last-minute change to our order, and she went the extra mile to accommodate our request without any hassle. Her excellent customer service really gave us peace of mind. A huge thank you as well to the installation team. They worked tirelessly from about 10am to 3pm to complete the installation, and their dedication really showed. They were professional, meticulous, and made sure every blind was installed perfectly while keeping the place clean and tidy. It is not often you come across a team that delivers such great service from sales to installation. Thank you to Chloe and the installation crew for making the entire experience so seamless. Highly recommended to anyone looking for quality window blinds and outstanding customer service!”
“Good and speedy installation. good quality. The technicians should explain better, due to a protuding 5mm gap on the bottom portion, the installation from the bottom to the ziptrack ceiling is not 90 degrees angle but slightly slunted. This could be resolved by putting a spacer on the top rather slant the whole installation to the ziptrack mounts. Otherwise its perfect. 9/10”
