What Can Go Wrong on a £100K Build

Most homeowners assume a good builder means a smooth job. But even great builders miss things, and most faults don't show up until after handover.

A £100K renovation might span three months, six rooms, and multiple trades. Things will go wrong — the question is whether they're caught in time.

🔍 Seven Common Faults (and Why They're Hard to Catch)

Seven faults across thirteen weeks. Less than one per week. Would you spot them?

• Roof Flashing — Only shows after first rain. Requires scaffold to inspect properly.
• Drainage Gradient — Only visible in heavy rain with pooling. Looks fine at handover.
• Electrical Load — Circuit trips when appliances run together. Needs load calculation to predict.
• Insulation Gaps — Only noticed during first cold snap. Hidden behind walls by then.
• Joinery Finish — Doors stick or gaps appear over time. Easy to dismiss as "settling."
• External Render — Hairline cracks develop weeks later. Looks perfect at handover.
• Ventilation — Musty smell or damp risk emerges gradually. Needs airflow testing to verify.

💬 What It Actually Costs

From a recent BuildROI consultation:

✅ What BuildROI Does Differently

BuildROI isn't just oversight — it's builder-backed protection at every stage.

• Stage-by-stage verification — Work checked and documented before payment moves
• Insurance protection — Coverage during the construction phase
• Dispute resolution — Independent PM mediation if issues arise
• Resale-ready documentation — Complete evidence pack with photos, certificates, and warranties
• Trade-specific oversight — Ex-builders who know what good work looks like, with specialist backup when needed

Every part of the job is verified before payment moves. Every builder knows what's expected. Every homeowner gets proof, not just promises.

🏛️ Building Control vs. Project Management

Building Control inspectors ensure your project meets regulations — which is essential. But their role isn't to catch every quality issue or verify finishes.

BuildROI's Project Managers are ex-tradespeople who check quality at every stage — and call in specialists when needed. It's the difference between compliance and craftsmanship.
