PVC gutter: ₹100-300/running ft installed। GI (galvanized): ₹150-400। Indian homes often lack proper gutters — rainwater damages walls and foundation। Essential in heavy monsoon areas।

Rainwater Harvesting

Mandatory in many Indian cities (Chennai, Bangalore, Delhi)। Gutter → filter → storage tank। Saves water bill and is legally required।

⚡ CalcWolf Insight

Clogged gutters cause more foundation damage than any other single factor. Water overflowing near the foundation leads to basement leaks, soil erosion, and eventually foundation cracking. Clean gutters twice a year (spring and fall) or install gutter guards.
