What does garbage disposal install typically cost in New Brunswick?

Garbage disposals are relatively affordable to install in New Brunswick, typically running $300–$700 all-in for a standard under-sink unit — though the final number depends on your existing plumbing setup and whether any modifications are needed.

Here's how the cost breaks down across the range:

• Budget end ($300–$400): Basic 1/2 to 3/4 HP unit (think InSinkErator Badger or equivalent), straightforward swap-out where the drain plumbing and electrical outlet are already in place. Labour is minimal — an experienced plumber can knock this out in under an hour.
• Mid-range ($450–$550): A better 3/4 to 1 HP unit with sound insulation, plus minor drain reconfiguration if your P-trap needs adjusting to accommodate the new drain collar.
• Higher end ($600–$700+): Premium unit (InSinkErator Evolution series or similar), plus any electrical work needed if there's no switched outlet under the sink.

That last point is where costs can climb. If your kitchen doesn't already have a dedicated switched outlet under the sink, you'll need a licensed electrical contractor to add one — that's a separate cost of roughly $150–$300 depending on how far the electrician needs to run wire. In New Brunswick, electrical work must be done by a TIS-licensed electrician, and a wiring permit through NB Power is required. This isn't a DIY-it-yourself situation legally.

On the plumbing side, a licensed NB plumber must pull a permit from Technical Inspection Services (TIS) for any new or altered plumbing connection — and connecting a disposal to your drain system qualifies. That permit and inspection is typically factored into the plumber's quote, so ask specifically that it's included.

One thing worth flagging for older NB homes: if you're in a pre-1980s house in Fredericton, Saint John, or Moncton with original cast iron or galvanized drain pipes, your plumber may flag concerns about the disposal adding stress to aging pipes. It's worth a quick inspection while they're under the sink anyway.

The practical next step is to check under your sink before calling anyone — note whether there's already a switched outlet present and whether your drain has a double-bowl or single-bowl configuration. That information will help any contractor give you an accurate quote right away.
