What Is the Korea Construction Defects Damages Calculator?

This calculator estimates Korean construction-defect repair cost, depreciation, warranty-period status, consolation money, usage-loss amount, total claimable amount, and litigation economics.

The English page reuses the Korean construction-defect pure function. It applies category-specific warranty years and cost tables rather than a generic percentage of property value.

Important Note

Construction-defect recovery depends heavily on evidence, appraisal, warranty period, whether the defect is private or common area, and whether the builder or guarantor accepts responsibility.

Defect Categories and Warranty Logic

Category examples	Typical warranty period in model	Result effect
Structural defects	10 years	Longer warranty and high repair cost
Foundation and waterproofing	5 years	Often material in leak or settlement cases
Windows, plumbing, heating, electrical	3 years	Warranty status can expire quickly
Painting and finishing	2 years	Depreciation and evidence become important

Cost Components

Raw repair cost is calculated from category, subtype, severity, and area or count.
Final repair cost applies severity multiplier, depreciation, and warranty-period status.
Consolation money and usage-loss amount are added to estimate total claimable amount.
Litigation cost includes stamp fee, service fee, lawyer fee, appraisal fee, per-household cost, and expected compensation.

Inspection, Mediation, Warranty Bond, Lawsuit

The calculator compares dispute-resolution routes because a defect-inspection route, mediation, direct warranty-bond claim, and civil lawsuit have different costs and timing.

Joint lawsuits can reduce per-household cost, but they also require coordination and a consistent evidence package across households.

FAQ

Why does the same defect cost less after time passes?

The Korean model applies depreciation and warranty-period logic. Older defects can have lower recoverable repair amounts unless evidence and legal basis are strong.

Does a photo prove the defect amount?

No. Photos help, but repair estimate, inspection report, defect list, warranty documents, and expert appraisal are often needed.
