Homeowners unable to diagnose and repair wood rot damage before structural failure occurs

Homeowners discover rotted wood under bay windows and similar structural areas but lack the expertise to assess severity, determine root causes (moisture intrusion, poor drainage), and execute proper repairs without causing further damage. Current solutions fail because DIY advice is scattered across forums, professional contractors are expensive and hard to vet, and misdiagnosis leads to incomplete repairs that allow rot to spread, resulting in costly structural damage.
