Note: High-rise or difficult access adds 50–100% due to scaffolding/lift requirements. Concrete sill repair is essential to prevent water intrusion into wall cavities, which leads to rot, mold, and foundation damage. For minor to moderate spalling, a proper patch and sealer can extend sill life by 5–10 years. If reinforcement is exposed or the sill has visibly settled, replacement is the most cost-effective long-term solution.

Recommend a site-specific moisture test (e.g., plastic sheet taped for 24 hours) to confirm no ongoing water entry from above the sill. Prepared by: [Signature / Name] Review Date: [Date]
