Waterproofing in Singapore, ranked by real evidence
157 businesses · Honestfix score · checked 20 Sep 2026
How do I find the best waterproofing company in Singapore?
Start with proof, not promises. Check the business is a registered company. BCA registration applies to structural work, so ask whether the job needs it. Read its recent reviews for finished jobs like yours, not just a star average. Get a written quote that names the job and the call-out fee, then call two businesses, not one. The 157 waterproofing companies below are ordered by that evidence: what is on record, with the date it was checked. Nobody pays to be here or to move up.

Saved me a fortune. SGRoofing was not only the lowest quote I received but I am also very happy with the quality of work. Good professionalism throughout and would use again if needed.
Will recommend this contractor, diligent and a hard worker he is. He just finished renovating our whole house in a year, and he knows his priorities and what’s best for his clients. His roofing is the best quality build, with the house extension and home renovations.

We used GDT to replacement roof as well as to extend the roof-line over an expanded addition. The GDT team did a great job. They showed up on time, worked hard, cleaned up, and completed the projects quickly and as scheduled.

I recently had the pleasure of working with an exceptional waterproofing company for my roof leakage repair needs. From their prompt service to their satisfactory workmanship, I recommend Three Luck Construction. They accurately identified the source of the leak, utilized high-quality materials, and delivered a lasting solution. Their excellent communication and attention to detail made the entire process stress-free. They also provided me with a one year warranty for the waterproofing work they did for me.

Tried their product for one bathroom first. Very satisfied and used for other areas. So far it is much better than the PU injection I did last time. Highly recommend.
