What do recent reviews say?

Most reviewers praise Mark and his team for bathroom renovations, hot water work, and emergency response. However, a significant minority report quote overruns, job quality issues, and concerning gas installation practices including unlicensed personnel and lack of proper certification. Experience varies widely.

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

Tap Tech Plumbing and Gas

5.0(142)✓ Google-verified

Early morning emergency drain calls and routine jobs alike get a same-day or next-morning arrival from Tap Tech's crew. Staff like Caiden and Nay combine speed with honesty, often spotting secondary issues during a job (cracked pipes, worn hot water systems, blocked gutters) and quoting separately rather than upselling. Reviewers praise transparent pricing, proactive text updates when delayed, and willingness to let customers decide what work happens. Bathroom taps, sewage backups, garden hoses, and blocked drains all get the same professional, tidy treatment. The business has built a pattern of repeat customers and referrals across Perth metro and beyond.

Paul at Westbest is known for fair pricing, fast turnaround, and clean workmanship across plumbing jobs from taps to bathroom renovations. He operates over weekends, explains work clearly, and cleans up after himself. One serious complaint about aggressive conduct and cost inflation when a homeowner was away overseas stands out starkly against the strong positive consensus.
