Duct Replacement & Repair
For ductwork beyond cleaning.
Not every duct can be brought back with a clean. Where insulation has failed, joints are leaking or the substrate is contaminated past saving, we replace it - properly sealed, properly insulated, properly commissioned. The result is quieter, more efficient air movement and lower energy waste.

When cleaning isn't enough.
Some ductwork can be brought back with a repair. Some is past it - and keeps costing you in leaks, energy and air quality until it's swapped. Here's how we call it.

Every recommendation comes with the reasoning, a fixed price, and airflow verification at handover - so you only replace what's actually done.
