Home Leak Fix publishes general DIY information for homeowners. Water intrusion can involve structural defects, electrical hazards, mould contamination, roof-height work, insurance documentation, hidden rot, and local building regulations.
Stop DIY work and call a qualified professional when a leak is active, unsafe to access, connected to wiring, related to structural movement, inside a roof assembly, affecting a shared building, or not clearly understood. Temporary patches should not be treated as permanent repairs unless the material and building detail support that use.
