Choose by what you need
Start with an assessment of the water entry point. Both providers publish roof, bathroom and other waterproofing enquiries. Hydroseal lists external-wall and concrete work; Roofing Singapore also lists roof repair and replacement. Compare the proposed repair boundary, access and preparation, then the treatment, making-good work, exclusions and complete quotation. Neither a visible stain nor a supplier list establishes the diagnosis.
