Reliable Commercial Ducting and Hood Services
Leaky ducts in office buildings aren’t just a maintenance issue – they’re a silent drain on energy, comfort, and indoor air quality. Many commercial properties in Singapore lose up to 40% of their conditioned air through small, hidden duct leaks. That’s where Delta Sirius comes in.
With 30+ years of experience in commercial ducting and hood services, we help office buildings seal and restore their HVAC systems – efficiently, safely, and without disruption.
Why Commercial Hood and Duct Sealing Matters?
In a commercial office, duct systems work nonstop – moving conditioned air to workstations, meeting rooms, and shared spaces. But over time, wear and tear causes small leaks at joints, seams, and transitions.
This leads to:
Sealing these leaks improves airflow, lowers energy consumption, and enhances comfort – without needing to rip open ceilings or walls.
What Do We Offer?
At Delta Sirius, we deliver complete commercial ducting and hood services tailored to your office environments. Whether you’re fixing an old system or sealing a newly installed setup, we bring expert diagnostics and fast results. Here’s what’s included:
Our Aeroseal technology seals leaks from the inside – non-invasive and highly accurate.
You’ll see verified before-and-after leakage rates.
We ensure your system meets BCA, SCDF, and Green Mark efficiency standards.
Clear documentation plus maintenance tips to keep your system running efficiently.
How Does Our Process Work?
We designed our commercial ducting and hood services to be fast, data-driven, and hassle-free. Here’s how our team approaches it, step by step:
These leaks contribute to:
Traditional manual sealing often fails to reach hidden or inaccessible areas. Aerosol duct sealing overcomes these limitations—sealing leaks from the inside out with patented precision.

Frequently Asked Questions
Pricing depends on duct size, leak severity, and building layout. For most offices, costs start from $2,500 to $5,000. Larger systems or those with complex access points may be higher. We provide site-based assessments and transparent quotes – no hidden fees.
Most sealing jobs are completed in one working day. For multi-floor systems or older buildings, it may take up to 48 hours to complete. We schedule work during off-peak or after-hours to avoid disruption to your team.
We recommend a duct inspection every 2 to 3 years, or sooner if your building has persistent airflow issues, uneven temperatures, or high utility bills. Office environments typically experience wear due to continuous HVAC use.
es. Our sealing process reduces air leakage, improves ventilation efficiency, and helps meet SCDF fire code, BCA ventilation requirements, and Green Mark energy performance standards. We also provide documented test results.
For most offices, no full shutdown is needed. We isolate duct zones and work in sections to keep core systems running. If a complete seal is required, temporary downtime may be scheduled during non-peak hours.
No. Cleaning removes dirt and debris, while sealing repairs air leaks to restore proper airflow and system pressure. We often recommend sealing after cleaning to lock in efficiency improvements and prevent recontamination.
Yes. Leaky joints and loose connections often cause whistling, rattling, or vibration sounds. Sealing stabilises airflow and pressure, often leading to quieter HVAC performance across the office.
Absolutely. We often work on systems with flawed or incomplete installations. Our team identifies problem areas, corrects gaps, and applies durable internal seals to bring your system up to performance standards.
Yes. We offer annual duct performance check-ups, including airflow testing, minor resealing, and system health reports. Ideal for offices aiming to maintain energy efficiency and avoid unexpected HVAC issues.
