What reviewers think

Recent reviews split sharply: older five-star ratings praised staff like Azfar, Amy, and Brendan for professionalism and customization. But recent one-star complaints dominate, citing multi-year delays, repeated defects ignored after handover, unresponsive communication, and unexpected cost increases of up to $60k. One reviewer credited Brendan's management for salvaging a four-and-a-half-year build, yet systemic issues with contracts, material delays, and follow-up remain widely reported.

Based on limited recent reviews, so treat this as low-confidence.

Praised for
  • attentive project manager (Brendan)
  • professional staff when engaged
  • design flexibility and customization
Watch-outs
  • severe project delays (years beyond contract)
  • persistent defects post-handover
  • poor communication and unresponsive to requests
  • hidden costs and contract disputes
  • lack of transparency on pricing and scope

Think twice if: Projects frequently exceed multi-year timelines, defects persist post-handover, and communication breaks down during disputes or issues.

Strengths

Worth knowing

  • Brendan credited for project management improvements mid-build; staff Azfar, Amy, Lydia also named positively in older reviews

  • post-handover defects include drainage, NBN conduit issues, and paving damage left unresolved for months
  • cost increases of up to $60,000 reported on single projects

Smith & Sons Renovations & Extensions Perth South Metro

3.6(12)✓ Google-verified

George Greene leads a skilled team delivering major renovations and extensions on time and to high standards when the project proceeds. However, initial contact and pre-contract phases show serious gaps: several prospective clients were ghosted or ignored when requesting quote adjustments or follow-up, creating a stark divide between those who've completed work (very satisfied) and those who didn't get past the inquiry stage (frustrated and walked away).
