Ductwork is the network of ducts that moves air through a building as part of its ACMV or HVAC system.
It carries cooled or ventilated air from the system to different spaces, while other ducts may return or exhaust air from the building.
When layouts or building requirements change, ductwork may need to be installed, extended, rerouted or relocated. Existing systems may also require repair, leakage rectification or airflow balancing.
We build it, modify it, repair it and verify how it performs.
What we do
Ductwork Services
From new installation and modification to repair, fabrication and airflow testing, we support ductwork through different stages of a commercial project.
We measure airflow, make the required adjustments and balance the system against project requirements before handover. Results can be documented where required for project review or handover.
We support contractors, building teams and businesses that need ductwork installed, modified, repaired or tested as part of commercial projects and existing buildings.

Why Ventix
Why Choose Ventix?
Ductwork-first expertise, clear coordination and practical execution from site assessment to handover.
Ductwork-First Expertise
We focus on duct installation, modification, repair and airflow performance rather than trying to cover every M&E trade.
New + Existing Systems
From new fit-outs to existing ductwork that needs rerouting, relocation or rectification, we work with both new and existing systems.
Clear Scope & Quotation
The required works, pricing and scope boundaries are defined clearly before execution.
One Accountable Contact
Where applicable, one project contact coordinates the work from site review through completion.
Measured, Not Assumed
Where testing is required, airflow is measured and adjusted against the project requirements rather than judged by appearance alone.
Documented Handover
Site records, photographs and testing documentation can be provided where required by the project scope.

Common questions
Questions Before You Engage a Ductwork Contractor
A few practical answers about duct installation, modification, repair and testing before you arrange a site survey.
Yes. Existing ductwork may need to be rerouted, extended or relocated when partitions, rooms or tenant layouts change. The required work depends on the existing system and the new layout.
Yes. We can assess duct leakage, damaged sections, insulation-related issues and other existing ductwork problems, then recommend the required repair or rectification scope.
Testing, Adjusting & Balancing, or TAB, is the process of measuring airflow and making adjustments so the system performs according to the required project conditions.
Yes, subject to site conditions, building requirements, access arrangements and the agreed work schedule. The site requirements should be reviewed before the work programme is confirmed.
Where available, send us the project location, current issue or required work, site photos, drawings, approximate scope and required timeline. Our team can then review the next step.
Yes. Ventix also supports kitchen exhaust ductwork and selected fire-rated and smoke-control ductwork projects, depending on the project scope and technical requirements.
