How Much Does Garburator Installation Cost in Coquitlam, BC?
Typical cost in Coquitlam
$400
$250 low · $650 high
Installed price for a 1/2 HP unit: the garburator, labour, mounting hardware and the drain connection · Updated July 2026
Installing a garburator in Coquitlam costs $250 to $650 installed, and most homeowners pay around $400 for a 1/2 HP unit under a standard kitchen sink. Few plumbing purchases split as evenly as this one: the machine and the labour cost roughly the same. The unit is $230 on a Canadian shelf; getting it hung off the sink flange, wired, and piped into the trap is another few hundred. Prices below separate the two, because BC quotes blend them constantly and that is how a $230 appliance turns into a $1,000 line item.
Expect $250 to $650 installed in Coquitlam for a 1/2 HP unit, about $400 on a typical job, and roughly $200 in labour if you buy the machine and the old mounting bracket fits the new one. A first install in a kitchen that has never had a disposer costs more, because the discharge has to be cut into the trap arm. Check the city's sewer bylaw and, in strata, the building rules, since a number of BC municipalities would rather food scraps went to the green bin.

| Labour only, you supply the unit | $200 | $400 | $600 |
| 1/2 HP unit supplied and installed | $350 | $500 | $650 |

What's in the Price — and What Isn't
In the price
- The garburator itself on a supply-and-install quote, stated by horsepower and model
- Old unit disconnected, unhooked from the mount and carried out
- New sink flange, mounting assembly and gasket where the old hardware doesn't match
- Discharge tube cut and fitted into the trap arm, with the dishwasher inlet knocked out and connected if you have one
- Running it under water with the tap open to check the mount seal and the trap joints
Costs extra
- A switched receptacle in the cabinet where none exists — that's an electrician
- Replacing a corroded basket strainer or a sink with a non-standard drain opening
- Repiping a sink drain that was never plumbed for a disposer
- Clearing an existing kitchen blockage downstream of the trap
- Air-switch or air-gap fittings drilled into a stone counter
Ask which unit and which horsepower, by model name. BC quotes for this job routinely blend the machine and the labour into one number, and the difference between a 1/2 HP and a 1 HP install at the same shop is $440. A $230 shelf price on the unit gives you the arithmetic to check any quote you're handed.

What Moves the Price
- Horsepower
- The clearest price step in this category, and one BC price list publishes both ends of it: $627 supplied and installed for a 1/2 HP Badger-class unit, $1,067 for a 1 HP model. The bigger motor is quieter, grinds finer, and jams less on fibrous scraps. It is also more than twice the price.
- Whether the mounting bracket can be reused
- Garburators hang off a mounting assembly clamped to the sink flange. Where the existing bracket matches the new unit, a Vancouver drainage company puts the swap at 60 to 90 minutes. Where the whole sink-flange mount has to come off, or the last install used non-standard hardware, it's 90 to 120 minutes and a new mount kit.
- Who supplies the machine
- A 1/2 HP Badger 5 with cord is $230 from a Canadian InSinkErator distributor. Labour-only replacement of a homeowner-supplied unit is published at $213 in BC, and labour-only installation more broadly at $250 to $550. Buying the unit yourself is worth roughly $100 to $150 against a supplied-and-installed quote.
- Power under the sink
- Some units ship with a cord and some with a bare connection box. If the cabinet has no switched receptacle, that's an electrician and a wall switch, not a plumbing line item. Corded models exist for exactly this reason and are worth specifying when you buy.
- The dishwasher tie-in
- A garburator has an inlet spigot for the dishwasher drain, and it ships with a knockout plug still in place. Leave the plug in and the dishwasher won't drain. That connection is routine on a new install and is one reason both appliances tend to get quoted together.
- Taking one out instead of replacing it
- A live scope with its own price. Removing a garburator means repiping the sink drain back to a straight tailpiece and trap, published at $325 in BC. Some strata buildings and older Vancouver walk-ups don't allow them at all, which is when this becomes the job.

How the Job Actually Goes
-
Checking the mount and the power
Whether the existing mounting assembly matches the new unit decides most of the labour. So does whether the cabinet has a switched receptacle and whether the new machine came with a cord.
Included, though the van-out fee is billed separately
-
Old unit down
Power off at the breaker or unplugged, discharge tube separated, dishwasher hose released, and the unit twisted off its mounting ring with a hand underneath. It is heavier coming down than expected and always holds water.
Part of the labour
-
Sink flange and mount
Where the hardware doesn't carry over, the old flange comes out, the sink opening gets cleaned back to bare metal, and a new flange gets bedded in plumber's putty with the mounting ring drawn up evenly underneath.
Adds 30 minutes when the bracket can't be reused
-
Hanging the unit and connecting the drain
Motor lifted onto the ring and locked, discharge tube cut to length and fitted into the trap arm, and the dishwasher knockout punched out and the hose clamped on if there's a dishwasher on that side.
The bulk of the labour
-
Power, then run it wet
Cord into the switched receptacle or wired to the switch, then the tap runs while the unit does, with a hand at the flange and a torch on every joint under the sink. Cold water and a full flush after, not hot.
Included; a new switched receptacle is an electrician's line
Do It Yourself or Hire a Pro?
Doing it yourself
- A like-for-like swap onto an existing, matching mount is genuinely straightforward: unplug, twist the old unit off, twist the new one on, reconnect the discharge
- The economics are plain. $230 for the unit against $319 to $627 supplied and installed means the labour you're buying back is worth $100 to $400
- No permit applies to exchanging an appliance on an existing sink drain
- The sink flange seal is the whole job. Bed it badly and you get a slow drip into the cabinet that nobody notices until the base swells
- Holding 6 kg of motor overhead with one hand while turning a mounting ring with the other is the part the videos skip
- Forgetting the dishwasher knockout plug is the most common error, and it presents as a broken dishwasher rather than a garburator fault
- If the discharge tube doesn't line up with the trap arm, you're cutting and re-piping under the sink, which is where a 45-minute job becomes an afternoon
Hiring a licensed pro
- Mount seated and sealed properly, which is the failure point you can't see once the unit is up
- Discharge and trap re-piped cleanly if the geometry doesn't suit, rather than bodged with flex tubing
- Flat-rate shops publish the number by horsepower tier, so the price holds whether it takes an hour or three
- A second opinion on whether the sink drain is the problem at all, when the trouble is further down the branch line
- Supply-and-install pricing on a $230 machine carries a visible markup
- A call-out charge of $169 to $189 at flat-rate shops can rival the labour on a swap
Our take: Swap your own if the existing mount matches the new unit, the cord and receptacle are already there, and you can get the discharge to meet the trap without re-piping. Bring in a plumber for a first install, for a sink that has never had a disposer, for anything needing a switch in the wall, or when you want a garburator taken out and the drain put back to a plain tailpiece.
Signs It's Time to Replace
- A hum with no rotation, meaning the flywheel is jammed and the reset has tripped
- Water in the cabinet under the sink, usually the flange seal or the discharge gasket rather than the motor
- Rattling that isn't cutlery, which is a loosened mount or a broken impeller
- Slow drainage on the disposer side while the other basin runs freely
- A unit old enough that the grinding chamber has rusted through, which shows as staining or drips from the body itself
- A dishwasher that won't empty into a newly installed garburator, which is almost always the knockout plug left in place
How to Keep the Cost Down
- Buy the unit yourself and pay labour only. A 1/2 HP Badger 5 with cord is $230 from a Canadian distributor, and BC labour-only replacement is published at $213
- Think hard before paying for horsepower. The published step from a 1/2 HP to a 1 HP install at one BC shop is $627 to $1,067, which is a lot for a quieter motor in a household that mostly grinds coffee grounds
- Buy a corded model if your cabinet already has a receptacle. Choosing a hard-wire-only unit can add an electrician to a plumbing job
- Get it done in the same visit as any other under-sink work. The call-out fee lands once, and the cabinet is already emptied
- If the old one is jammed rather than dead, try the hex key in the bottom and the reset button before you buy anything. That's a five-minute fix on a machine plenty of people replace
Coquitlam Notes: Permits, Homes, Rates
Gas permits route through Technical Safety BC ($116 on a contractor permit for a 2026 water-heater swap); the City of Coquitlam handles plumbing, with a $79 minimum covering the job.
The 1970s and 80s split-levels here carry long, flat branch runs between half-storeys, which is the worst geometry for anything ground up and washed down with cold water. Those kitchens do tend to have deep double sinks, so the mount itself is easy. Up on the Plateau the newer subdivisions are PVC with real fall, and a lower-floor suite kitchen is common enough that plenty of houses have two sinks arguing over one branch.
Tri-Cities rates run a notch below Vancouver proper.
Questions to Ask Before You Hire
- Which unit and what horsepower, by model name, and is it in the price?
- Does the quote assume the existing mounting bracket can be reused?
- Is there a call-out charge separate from the install line?
- Are you connecting the dishwasher drain, and is the knockout plug part of that?
- Does the cabinet need a switched receptacle, and who is arranging the electrician?
- What's the labour warranty on the flange seal, and how long is the manufacturer's on the unit?
While the Plumber Is There
Call-out time is a big share of any bill — if one of these applies to your home, pricing it in the same visit usually beats a separate appointment.
The dishwasher drains through the garburator's inlet spigot on most BC kitchens, so the two share a fitting and a cabinet. Doing them in one visit means one call-out and one set of connections tested together.
A new garburator won't fix a kitchen branch line coated in years of grease. If the sink was draining slowly before the unit failed, the pipe is the job and the machine is the symptom.
Kitchen lines that have fed a disposer for a decade build a hard grease layer that a cable bores a hole through rather than removing. If the same sink has been snaked twice, jetting is the version that actually clears it.
