What Most Calculators Don’t Tell You (Critical Insights)

1. Cheapest Is NOT Best

Many cheap policies exclude:

• theft of materials
• delays
• materials in transit

👉 That can cost you tens of thousands later.

2. Builder vs Owner Policy Matters

• Contractor policy → often cheaper
• Owner policy → more control

Choosing wrong can increase cost significantly.

3. Timeline Mistakes Cost Money

If your project runs longer:

👉 you must extend the policy → extra cost
