How much does it cost to shock a well?

Do-it-yourself with store bleach runs $10 to $50 in materials plus your own math and guesswork. Pre-measured chlorine sanitizer packs run about $45. A professional shock treatment runs roughly $80 to $650, and a full contractor well cleaning runs $1,500 to $3,000. Our chlorine dioxide kit is $350 for the box plus $49 per 5-gram sachet your well needs, so a typical three-sachet well is $497 and a small well pays less.

The spread inside the pro range tracks what is included: a simple chlorine drop is the low end, and brushing, redevelopment, or repeat visits climb toward the high end.

The honest way to compare the options is per solved well, not per bag of chemicals: a cheap shock that lets the problem return in eight weeks costs more by spring than doing it right once. Our kits-compared guide walks all four options.
