Getting accurate bids in North Carolina
A quoted price only means something if you can compare it to others. Ask every contractor for an itemized breakdown — materials, labor, equipment, overhead, and permits listed separately — instead of one bundled number.
- Get at least 3 bids from contractors licensed to work in North Carolina. One quote tells you nothing about the local market range.
- Watch for outliers. A bid more than 30% below Ximator's estimate often means cut corners — skipped permits, uninsured subs, or substandard materials. A bid 30%+ above usually means padding.
- Confirm what's excluded. Site prep, permit fees, and disposal costs are the line items contractors most often leave out — ask explicitly before signing.
- Verify licensing and insurance before work begins, not after a dispute starts.
