Tin Shui Wai — Waterproofing Works

Window frame sealant strips had hardened and shrunken, and external wall structural sealant had cracked — causing water ingress during heavy rain and damaging walls and window sills. Amgen removed all external wall structural sealant and replaced the sealant edges, then re-applied structural sealant and glass sealant throughout the exterior, thoroughly resolving all seepage issues.
