Understanding the Cost to Replace a Water Valve Under Your Sink
For construction professionals, understanding the cost to replace a water valve under a sink is crucial for accurate project planning. The typical cost ranges from $120 to $285, including materials, labor, and permits. This guide provides a detailed breakdown of these costs and offers insights into optimizing your workflow.
Why a Healthy Shut-Off Valve Matters
- Protects cabinetry and flooring from sudden leaks
- Enables safe fixture upgrades without shutting off the whole house
- Extends the life of supply lines and faucets
- Brings older homes up to current plumbing code
The Hidden Costs of Ignoring a Faulty Valve
- Mold remediation from unnoticed drips
- Emergency plumber callouts at premium rates
- Cabinet replacement when water damage spreads
Main Factors Driving Replacement Cost
1. Valve Type
- Standard angle stop in chrome-plated brass costs less than quarter-turn ball valves in solid brass
2. Pipe Material
- Copper, PEX, or CPVC each require different fittings and labor approaches
3. Accessibility
- Tight vanity corners increase labor time compared with open kitchen sinks
4. Local Code Requirements
- Some municipalities mandate lead-free valves or require permits for supply line alterations
5. Emergency vs. Scheduled Service
- After-hours calls can raise labor rates by 50–100%

DIY or Hire a Pro?

Case Study: Kitchen Remodel in Providence, RI
A local design-build firm partnered with CountBricks for a 1960s kitchen overhaul. The original copper angle stops had seized, so every sink valve needed replacement before new cabinetry arrived. Here’s how CountBricks saved the team time and money:
Project Snapshot
- Scope: Replace 2 hot and 2 cold water valves, upgrade to quarter-turn ball valves, install braided stainless supply lines
- Constraints: Tight timeline—cabinet delivery in 48 hours, existing shut-off to branch line inaccessible
CountBricks Solution
- Voice Estimate: The site supervisor opened a live session, stating “two double-valve replacements, copper pipe, limited clearance.” In under 90 seconds, CountBricks produced a $468 bundled quote covering valves, labor, and expedited materials.
- Automated Procurement: By selecting “auto-order,” the system sourced lead-free valves from the nearest distributor and scheduled same-day delivery.
- Workflow Guidance: Onsite plumbers followed in-app steps—localized water isolation, pipe prep, sweat-in connections—and uploaded completion photos for instant client approval.
- Instant Billing: As soon as the homeowner signed off, CountBricks generated an invoice and processed digital payment, eliminating back-office delays.
