Frequently asked questions

How long does snag take?

4–8 weeks for an initial snag walk-through and first-fix pass. Final closure another 2–4 weeks.

What is the snag retention?

5% of contract value, typically. Released half at handover, half 6 months later once the snag is closed.

What is a Certificate of Compliance on Completion?

A signed certificate from the Assigned Certifier confirming the building was constructed in accordance with the plans, specifications, and BCAR. Required for occupation.

Do I move in before snag is closed?

Yes, often. But hold the retention as your leverage. Most contracts allow occupation once CCC is filed.

Should I get a snag survey done?

Yes — a professional snag surveyor costs €400–€900 for a 180 m² house and finds 30–60 items you wouldn't.
