Notes
- • Class 2 damage affecting 300 sq ft with clean water.
- • Emergency response within 24-48 hours significantly reduces total restoration cost.
About the Water Damage Calculator
Water damage restoration involves water extraction, structural drying, sanitization, and repairing damaged materials. Costs vary dramatically based on the damage class (severity), water source contamination level, area affected, and whether mold has developed. Acting within 24–48 hours of water damage can reduce total costs by 30–50%.
How We Calculate Water Damage
We estimate costs using IICRC damage classification standards. Each class has a per-square-foot rate for extraction and drying, adjusted by water contamination type (clean, gray, or black water). Material replacement costs are estimated based on the percentage of affected area likely needing replacement at each damage class. Mold remediation is calculated separately.
Factors That Affect Water Damage
Major cost factors include: damage class and severity, water source (clean pipe vs. sewage), area affected, mold presence and extent, materials damaged (drywall vs. hardwood vs. concrete), response time (faster = cheaper), and local labor rates.
Planning a larger project? You may also want to estimate costs for house repiping cost, crawl space encapsulation cost, or foundation repair cost.
