Construction delays, cost overruns, substandard materials — we analysed 12,000 contractor reviews to show you exactly what to look for before signing.
Construction is one of the highest-stakes service categories — errors are expensive, reversals are disruptive, and bad actors can disappear with advance payments. We analysed 12,000 contractor and construction service reviews on WhoIsAtTop to build a practical guide for homeowners and businesses hiring in 2024.
The advance payment trap
The single most common complaint in construction reviews — appearing in 38% of all negative reviews — involves contractors who demand large upfront payments and then slow progress significantly or stop appearing on site. Top-rated contractors structure payments in milestone instalments tied to inspectable deliverables. Never pay more than 25% upfront.
"We paid 40% upfront based on a verbal promise. Work stopped after week two. The review I found after the fact had warned exactly this." — Verified WhoIsAtTop Review
What the best contractor reviews mention
Positive construction reviews share a specific vocabulary: daily site updates (photos or brief messages), proactive communication about material delays, and a written scope of work referenced throughout the project. When a reviewer mentions "daily photos," it's almost always a 4 or 5-star review.
Verifying credentials before you hire
Ask for GST registration, a portfolio of completed projects you can visit in person, and references from clients with similar project sizes. Contractors with verified profiles on WhoIsAtTop have completed identity verification — a meaningful filter given the volume of fly-by-night operators in the sector.
