What recent reviews say

Gradecool delivers strong technical service on repairs and urgent jobs, with named technicians consistently praised for speed and clear explanations. However, standard servicing quality is uneven. Several customers report inadequate cleaning on routine visits, aggressive upselling of chemical washes, and poor complaint handling when things go wrong. Late arrivals and weak accountability for preventable damage (like flooring issues) have created lasting dissatisfaction for some long-term clients.

Recent shift: Recent 1-star review (2 days ago) reiterated pattern of substandard workmanship and late arrivals, suggesting complaints remain unresolved despite past publicity.

Worth knowing

Named technicians praised: Michael, Ming, Niki, Mr Liu, Mr Seng
Recurring complaint: substandard cleaning on regular servicing visits; third-party audits found work incomplete

Late arrivals documented: 3-4 hours after scheduled time
Damage incident: water seeped through allegedly inadequate protective sheeting during servicing, damaging customer's laminate floor; company blamed customer for old flooring rather than accepting responsibility
