Basement & Secondary Suite Ventilation
A legal suite needs its own exhaust and fresh-air path. I plan and install the bathroom, kitchen, dryer, and HRV/ERV ducting a basement or secondary suite needs, coordinated with the renovation.
What I do
- Plan bathroom, kitchen, and dryer exhaust for a suite
- Rough in HRV/ERV ducting for suite fresh air
- Route exhaust to proper exterior terminations
- Coordinate duct runs around tight basement framing
- Sequence the work with the renovation and other trades
Common problems I fix
- A suite bathroom or kitchen with no real exhaust path
- Dryer venting with nowhere practical to go in a basement
- Stuffy, damp suites with no fresh-air supply
- Low ceilings and beams leaving no room for standard duct
Good-fit projects
- Adding a legal secondary suite
- Finishing a basement with a bathroom and kitchen
- Bringing an existing suite up to a workable ventilation standard
- New builds with a suite in the plans
A basement or secondary suite is really a small home inside a larger one, and it needs its own ventilation to match: exhaust for the bathroom and kitchen, a dryer vent if there is laundry, and a fresh-air path so the space does not turn damp and stale. In a tight basement, fitting all of that around low ceilings and beams is the hard part.
What a suite needs
Each wet room needs real exhaust to the exterior: a bathroom fan ducted outside, a kitchen hood or exhaust, and a dryer vent on the shortest practical route. Because suites are often tighter and more enclosed than the main house, they also benefit from HRV or ERV ducting to bring in fresh air and carry stale air out without simply leaking heat.
Working in tight basement framing
Low ceilings, beams, and finished space above make basements the place where standard duct will not fit. This is where fabricating transitions and routing runs to the actual framing matters. I plan the duct paths so they tuck into the available space instead of dropping the ceiling further than it has to.
Plan it with the renovation
The time to get suite ventilation right is during the build or renovation, before insulation and drywall close the walls and ceiling. Roughed in at the right stage and coordinated with the other trades, the exhaust, dryer, and fresh-air ducting all land where they should without fighting the finished space later.

Frequently Asked Questions
What ventilation does a basement suite need?
A suite needs exhaust for its bathroom and kitchen, a dryer vent if there is laundry, and a fresh-air path (often HRV or ERV ducting) so the space does not stay damp and stuffy. I plan all of it to suit the suite and route the exhaust to proper exterior terminations.
Can you fit ventilation ducting into a low basement?
Usually, yes. Tight basements with low ceilings and beams are where standard duct does not fit, so I fabricate transitions and route runs to work with the framing. Planning it during the renovation, before drywall, makes a big difference.
