Sydney Sealed is the trusted specialist for strata committees, owners corporations, building managers and property managers across Sydney. We deliver fast, documented, compliant leak repairs — with full reporting for insurance, legal and strata records.
We Understand Your Challenges
Managing leak repairs in strata buildings is complex. Sydney Sealed is built specifically to handle the documentation, compliance and communication demands of strata and property management.
Residents reporting water ingress, ceiling stains or damp smells — you need a specialist who responds fast and documents everything.
Insurers require detailed reports, photographic evidence and cause-of-loss assessments. We provide everything you need.
Determining whether a leak is common property or lot owner responsibility requires expert assessment and clear documentation.
A single balcony or shower leak can affect multiple apartments below. We trace the source and repair it correctly the first time.
Strata committees need predictable costs. Our preventative maintenance plans help you budget accurately and avoid emergency repairs.
We provide clear, plain-English reports suitable for AGMs, committee meetings and owner communications — no technical jargon.
