Your garbage disposal suddenly stops working—food scraps pile up, odors linger, and your kitchen routine grinds to a halt. You’re not alone. Many U.S. homeowners face this frustrating issue each year and immediately wonder: how much for plumber to replace garbage disposal? The good news? Replacement is usually straightforward, and costs are predictable if you know what to expect. In this guide, we’ll break down everything—from average prices and hidden fees to DIY alternatives—so you can make an informed, stress-free decision.
What’s the Average Cost to Replace a Garbage Disposal?
According to HomeAdvisor’s 2024 data, the national average cost to replace a garbage disposal with a licensed plumber ranges from $150 to $950, with most homeowners paying around $430. This includes both labor and the new unit.
Here’s a quick cost breakdown:
Garbage Disposal Unit
$75 – $400+
Labor (Plumber)
$80 – $200/hour
Total Installation
$150 – $950
Note: High-end models (like InSinkErator Evolution or Waste King Legend) cost more but offer quieter operation, better grinding, and longer warranties.
What Factors Affect the Total Cost?
Several variables influence your final bill. Understanding them helps you avoid surprise charges.
1. Type of Garbage Disposal Unit
Basic (1/3–1/2 HP): $75–$150 — suitable for small households.
Mid-Range (3/4 HP): $150–$250 — best balance of power and price.
Premium (1 HP+): $250–$400+ — ideal for large families or frequent use.
2. Labor Rates by Region
Plumbers in urban areas (e.g., New York, San Francisco) often charge $120–$200/hour, while rural areas may average $70–$110/hour. Always get local quotes.
3. Existing Plumbing Condition
If your sink flange, drain pipe, or electrical wiring needs repair or updating, expect $50–$200 extra. Older homes (pre-1990s) are more likely to require modifications.
4. Removal of Old Unit
Most plumbers include removal in their quote—but confirm this upfront. Some charge $25–$50 extra if the old unit is corroded or hard to detach.
5. Permits & Electrical Work
Garbage disposals require a dedicated electrical outlet or hardwiring. If you lack one, an electrician may need to install it—adding $100–$300 to your total.
💡 Pro Tip: Ask your plumber if they offer a flat-rate installation fee. Many do (e.g., “$299 installed, including mid-tier unit”), which protects you from hourly surprises.

DIY vs. Hiring a Plumber: Which Is Right for You?
Replacing a garbage disposal can be a DIY project—but only if you’re comfortable with basic plumbing and electrical work.
✅ When DIY Makes Sense
You already own the right tools (basin wrench, plumber’s putty, wire nuts).
Your old unit is easily accessible and your sink has a standard 3-bolt mounting.
You’re replacing with the same brand/model (simplifies reinstallation).
Estimated DIY Cost: $75–$250 (unit only) + your time.
❌ When to Call a Pro
You smell gas or see water leaks near the sink.
Your home has outdated wiring (e.g., no GFCI outlet under the sink).
Local codes require licensed installation (common in California, Florida, and NYC).
According to the U.S. Consumer Product Safety Commission, improper disposal installation is a leading cause of kitchen sink leaks and electrical hazards. When in doubt, hire a pro.
Step-by-Step: What Happens During a Professional Installation?
If you hire a plumber, here’s exactly what to expect:
Turn Off Power & Water The plumber shuts off electricity at the breaker and closes the hot/cold water valves.
Remove Old Unit Disconnects drain pipe, electrical wires, and mounting assembly. Cleans residue from sink flange.
Inspect Plumbing & Wiring Checks for corrosion, leaks, or outdated components. Recommends fixes if needed.
Install New Disposal
Applies plumber’s putty to new sink flange.
Mounts unit using the 3-bolt system.
Connects discharge tube to drain pipe.
Wires unit to GFCI outlet or hardwires per code.
Test & Clean Up Runs water and turns on disposal to check for leaks, noise, or vibration. Removes old unit and debris.
Total Time: 60–90 minutes for a standard replacement.
How to Save Money on Garbage Disposal Replacement
You don’t have to overpay. Try these proven strategies:
Bundle Services: Need a faucet or sink replaced too? Ask for a package discount.

Choose Mid-Tier Models: Premium units rarely justify the 2–3x price jump for average households.
Get 3 Quotes: Use platforms like Angi or HomeAdvisor to compare local pros.
Check Warranties: Many disposals come with 5–10 year warranties—register yours!
