Yes. Every Catalyst project starts with a free inspection and a written, line-itemed scope of work using industry-standard Xactimate pricing. You see the number before any work begins.
Significant change orders only happen when the scope itself changes (e.g., we discover additional damage behind a wall during demolition). When that happens, we stop, photograph, document, and re-scope with you and the adjuster before continuing. No surprise charges.
