How Much Will You Save?
Here's an example for a 3,000 sq ft project:
Base price: 3,000 sq ft × $0.15/sq ft = $450
With Contractor+ (5% off): $427.50
You save: $22.50 per project
For contractors handling 20+ projects annually, Contractor+ savings can exceed $450/year — before volume discounts even apply.
