Cost to Main Water Shut-Off Valve Replacement in Hartford, CT (2026)

If you’re budgeting a main water shut-off valve replacement in Hartford, most projects run $185-$635, 6% above the $375 national average. What moves that number most is usually one thing: Valve Type Being Replaced. On its own it can swing the cost by $50 - $300, so that’s the decision to slow down on before you sweat the smaller stuff.

Easiest place to save: Replace all seized secondary shutoff valves (water heater, toilets, sinks) while the main shutoff is off. The marginal cost per valve is $50-$100 and saves multiple future service calls.
