How to Estimate a Main Water Shutoff Valve Replacement
Contractor method for estimating the replacement of the main water shutoff valve.
Replacing the main water shutoff valve is the valve plus labor, with access and a possible utility shutdown adding cost. It is a small job with a high cost of getting it wrong.
THE SHORT ANSWER
How do you estimate a main water shutoff valve replacement?
Add the valve and labor, then factor access and any utility shutdown. A $30 ball valve with $250 labor totals $280 on an easy access job.
Pick the valve type
Ball, gate and globe valves differ in price and reliability. Ball valves are common on modern mains.
- Ball
- Gate
- Globe
Assess the access
A valve buried behind drywall or in a tight crawlspace costs more than one in the open. Factor the access.
Include a utility shutdown
If the shutoff requires cutting the public supply, that coordination has a cost. Add it when it applies.
Total and validate
A $30 ball valve plus $250 labor totals $280 before access factors. Use the Main Water Shutoff Valve Replacement Cost Calculator.
