Old or frozen supply valves replaced with reliable quarter-turn ball valves. Serving Potomac and all of Montgomery County.

Call (301) 395-3831

The shut-off valve under your sink or behind your toilet is the valve that stops water when something leaks. If that valve has never been operated in 20 years and it is an old gate valve, there is a real chance it will not close when you need it most. Jacob replaces seized, corroded, and unreliable shut-off valves throughout Potomac with modern quarter-turn ball valves that are reliable and will not fail you in an emergency.

Potomac properties are often larger with more complex systems. Jacob gives every job a proper diagnostic before quoting. No one wants a rushed estimate on a Potomac home.

What Affects the Cost of Water Shut-Off Valve Replacement in Potomac, MD

No prices appear on this page because every job is different. Here is what determines the cost for a Potomac home:

  • Number of valves being replaced in the same visit
  • Supply line material and whether new supply lines are needed with the valves
  • Whether the main shut-off needs service before the individual valves can be replaced
  • Location accessibility under sinks, behind toilets, or at appliances

Jacob gives you a straight quote after understanding the job. Not a ballpark. Not an estimate with asterisks. A clear number for what the job actually requires before work starts.

Frequently Asked Questions

Cost depends on the number of valves and whether supply lines also need replacement. Combining multiple valves in a single visit is more efficient. Jacob works in Potomac regularly. Large properties with more complex systems get the same careful diagnostic before any work starts. Jacob gives you a clear quote after assessing which valves need replacement.
A gate valve uses a threaded stem that rises as you turn the handle. It takes multiple turns to open or close, and the gate inside corrodes and warps over time. A ball valve uses a quarter turn to open or close a ball with a hole through it. Ball valves are more reliable, last longer, and are far less likely to fail in the closed position.
Close each valve fully and then open the downstream faucet or flush the toilet. If water continues to flow after the valve is closed, the valve is not working. A functioning ball valve will cut off water completely with a single quarter turn. Test your main shut-off annually.
Original 1980s gate valves are worth replacing proactively, particularly on toilets, washing machine supply lines, and under sinks. If one fails open during a supply line break, the result is significant water damage. Replacing them on a scheduled visit costs far less than emergency water damage remediation.
Jacob assesses the existing supply line when replacing the valve. If the braided supply line is original or shows wear, replacing both in the same visit eliminates a future service call. If the line is newer and in good condition, the valve replacement alone is fine.
Yes. A main shut-off that does not close fully means you cannot stop water to the house in an emergency. Jacob replaces main shut-off valves and coordinates the brief main water interruption required to do the work.
For individual fixture shut-offs, the main should be closed before the work begins if the existing valve does not hold. Jacob always confirms the main shuts off before working on individual valves so there is no risk of an uncontrolled water release.
A single valve replacement typically takes 30 to 60 minutes. Multiple valves in the same visit are more efficient. Jacob shuts off water at the main, replaces the valves, restores water, and tests each valve before leaving.
Yes. Most kitchen and bathroom sinks have both a hot and cold supply shut-off. Jacob replaces both in the same visit. Replacing only one and leaving an aging valve on the other side of the same sink is not worth the saved time.
