George Chua,

They completed the Torch-On Membrane works, installation of air vent and application of liquid applied waterproofing. The workers were attentive to details, minimizing as many unforeseen errors as possible. The quality of the workmanship was evident, and the place was left in a spotless condition. Their professionalism could be seen in the field, and they were all very thorough when helping us with our queries. I would like to recommend Hydro-Seal Engineering in the event of any water seepage issues.
