Can Plumbers Install Rangehoods?
The short answer is yes — licensed plumbers are often the right trade to do it, especially when the rangehood is vented to the outside.
Here’s why.
What’s Involved in Installing a Rangehood?
Installing a rangehood is more than just mounting an appliance to the wall. A proper installation can include:
- Cutting and installing ducting
- Venting through the roof or an external wall
- Installing roof cowls or external vents
- Sealing penetrations to prevent leaks
- Managing condensation and airflow
- Ensuring the installation meets building codes
When ducting and roof penetration are involved, it becomes a plumbing and ventilation job, not just an appliance install.
Why Plumbers Are Qualified to Install Rangehoods
Licensed plumbers are trained and legally permitted to carry out mechanical ventilation work, including:
- Installing ductwork
- Penetrating roofs safely
- Weatherproofing and flashing
- Managing moisture and condensation
This is especially important when venting a rangehood through the roof, which is widely considered the best and most effective venting method.
A plumber ensures the job is done safely, efficiently, and compliantly — protecting your home from future issues.
What About Electricians or Handymen?
- Electricians may be required to connect the power supply if no outlet exists, but they generally don’t install ducting or roof vents.
- Handymen may be able to mount a recirculating rangehood, but they are usually not licensed to cut roofs or install ventilation systems.
For externally vented rangehoods, relying on an unlicensed installer can lead to:
- Roof leaks
- Poor airflow
- Condensation problems
- Voided warranties
- Non-compliant installations
When You Definitely Need a Licensed Plumber
You should use a licensed plumber if your rangehood:
- Is vented through the roof
- Requires new or upgraded ducting
- Is a high-powered or canopy-style rangehood
- Is part of a kitchen renovation or new build
In many cases, plumbers work alongside electricians to ensure both the ventilation and electrical components are completed correctly.
The Bottom Line
Yes — plumbers can install rangehoods, and in many situations, they’re the best trade for the job.
If your rangehood vents to the outside (especially through the roof), a licensed plumber ensures:
✔ Proper airflow
✔ A watertight roof penetration
✔ Compliance with regulations
✔ Long-term performance
Choosing the right professional from the start saves money, prevents damage, and ensures your rangehood actually does what it’s designed to do.
