New Build Snag Cost Calculator

What could your defects cost if your builder refuses to fix them? Select the issues you have noticed to get an estimate.

Snag Cost Estimator

Select the types of defects you have noticed. We will estimate the remediation cost if your builder refuses to fix them.

Estimates only. A professional snagging survey is the only way to accurately assess defect costs. Actual costs depend on severity, access, and contractor rates in your area.

How This Estimate Works

The estimate adds up a minimum and maximum private repair cost for each defect type you select. The ROI multiple divides those totals by an assumed survey cost of £380, rounded to the nearest whole number.

Defect typeRepair cost range
Cracked or damaged plasterwork£200–£500
Misaligned or sticking doors/windows£150–£400
Poor paintwork or finishes£100–£300
Drainage problems£500–£2,000
Damaged floor tiles or carpets£200–£600
Damp or condensation issues£500–£3,000
Faulty electrics£200–£800
Plumbing problems£300–£1,500
Roof or gutter issues£400–£2,000
Structural concerns£1,000–£10,000

Example: cracked plasterwork, misaligned doors and a drainage problem give an estimate of £850–£2,900, or 2–8× the assumed survey cost.

Limitations

  • Cost ranges are editorial estimates for typical private repairs, not quotes or a statistical survey. Regional labour rates and the extent of the defect change the real cost.
  • Covered defects reported within the builder warranty period should be put right by the builder at no cost to you — the estimate shows what is at stake if they are not.
  • Structural issues vary enormously; get a professional assessment.
