What do recent reviews say?

Gradecool attracts strong praise for responsive booking, thorough servicing by named technicians, and transparent pricing that customers find reasonable. However, persistent complaints about late arrivals, weak damage prevention on job sites, aggressive upselling of chemical washes, and poor handling of service failures when they do occur undermine reliability. The company's willingness to admit fault and make things right appears inconsistent across reviews.
