I needed a resolution to the problem of unruly outgrowth of plants on the RC roof at the 2nd level, where access is not easy. He did a good job in coordinating the rectification work and the result was more than satisfactory. The workmen did a neat and tidy job. Thanks to his diligence the whole proccess went through smoothly. #StanelyHoi #5star

- 5 stars, 10 Jul 2026: I have engaged Stanley Hoi as my ceiling was leaking in my dad's room as well as dining hall area. Stanley took some photos from the rooftop and able to spot the problems. He and his team then waterproof the rooftop landing area as well as my toilet area without hacking the tiles. The job was done 9 months ago and till now there is no further leakage problem at my place. Thank you, Stanley, for your professional services and problem solver. Will certainly recommend you to my contacts who face the same problem. Regards Richard Yeo
- 5 stars, 8 Jul 2026: Our unit had serious water seepage issues and we knew we needed a professional fix by a waterproofing specialist. Of all the companies I invited to inspect and quote, Mr. Bryan Chen from Proof-Tech stood out with his clear and detailed assessment of our issues, as well as his proposed solutions. Bryan was open, professional and provided excellent customer service throughout. I was also impressed with how thorough his quotation was -- importantly, Bryan also backed up his assessments and solutions with solid warranties, leaving me with no doubt that Proof-Tech was the right choice for the job.
