We shortlisted Allseal Waterproofing to patch some leakages on the bathroom floor between ours and our neighbour downstairs. Mr Aziz and his crew did a very thorough job- not just on grouting but ensuring our bathroom floor and piping are all sealed properly. We are very satisfied with the professionalism, the service and the neatness of the work. We find the cost very competitive and reasonable. Highly recommend ed. Thank you

Engaged Allseal for my roof and RC waterproofing. The workers handled the works relatively well and were receptive to our inputs. They are responsive and returned on a few times when we noticed areas that the paint was not even. Overall, happy to recommend to ask for a quote if you are looking for good works at competitive rates.

Am very pleased with the work done by Allseal Waterproofing Pte Ltd few months back and no further leakage or mould were detected to date. The previous contractor (Flux Solutions Pte Ltd) was very unresponsive and rude to after sales service and I decided to terminate them in favour for Allseal. I hope Allseal will continue with its responsive after sales service that I've experienced and recommend this company after the bad experience I had with Flux Solutions.
