Aeroseal
Aeroseal duct sealing is an automated technology for sealing leaks in ductwork in both residential and commercial buildings. Our advanced formula is very low tack, ensuring it only deposits where needed and maintains duct integrity.
Monitored in real-time for coverage and effectiveness, this technology improves HVAC efficiency, air quality, and comfort. Suitable for both new constructions and retrofits, it precisely meets any duct sealing requirement. (Source from https://aeroseal.com/how-aeroseal-duct/)
How Aeroseal Duct Sealing Works?
Source from https://aeroseal.com/how-aeroseal-duct/
Using a patented, non-toxic aerosol sealant, the process pressurizes duct systems, driving sealant particles directly to leaks to seal them from the inside without coating the entire duct.
This creates an efficient, targeted repair that improves airflow, enhances comfort, and boosts overall system performance.

Fast Application with Minimal Disruption
Automated sealing process that reduces downtime while delivering significant improvements in airflow efficiency and indoor comfort.
Aeroseal Duct Sealing Process
Step 1: Prep of the ductwork
Protect vital equipment and create pressure inside the ductwork
All registers are blocked or taped to pressurize the ductwork. Vital components, such as furnaces, coils, smoke detectors, and other sensors, are protected to prevent contact with the sealant. The supply and return duct systems are typically sealed separately.
Step 2: Connect the Aeroseal Equipment
Attach to the ductwork and run a pretest
The Aeroseal equipment is connected to the duct system through plastic lay-flat tubing, either via an existing register or an access hole in the ductwork. A pretest is conducted to measure initial leakage, like a Duct Blaster test. These results are used in the post-seal report to verify the seal’s effectiveness and estimate the time required for sealing.
Step 3: Seal the Ductwork
Inject sealant from the inside the ductwork, sealing only where needed
The equipment now begins spraying sealant directly into the duct system. Our non-toxic sealant is atomized and sprayed into the lay flat tubing where it’s exposed to heated air, removing moisture from the sealant make it temporarily sticky, allowing it to collect in cracks and gaps in the ductwork.
The sealant slowly builds up overtime, collecting onto itself, like the platelets in your blood after a scrape, until the gap is sealed. The entire process is monitored by our proprietary software, making automatic adjustments to pressure and flow rate to optimize effectiveness.
Step 4: Certify the Results
Verify final duct leakage and pack up equipment
When the target leakage rate is reached, the equipment is turned off, and any access holes are patched. Tape and blockers are removed, and the HVAC system is restored to normal operation. A detailed seal report is generated, comparing the before-and-after leakage rates to confirm effectiveness.

Frequently Asked Questions
Our service focuses on detecting and sealing air leaks within existing ductwork using the Aeroseal system. We don’t install or replace ducting – we work on service ducts in buildings that are already operational. The process includes leakage testing, internal sealing, post-sealing verification, and full performance reporting. It’s ideal for clients looking to improve HVAC efficiency, indoor air quality, or regulatory compliance.
Pricing depends on several factors: system size, number of duct sections, severity of leakage, and site access. In Singapore, most commercial projects start around SGD 5,000, with larger facilities scaling proportionally. After an on-site inspection, we provide a clear, fixed quote. Our pricing includes all diagnostics, sealing work, and documentation – no unexpected extras.
In most cases, our team completes the servicing of a service duct in a single shift – usually between 6 to 10 hours. For multi-zone systems or larger buildings, the project may span over two or three days. We schedule work based on your site’s operations and access windows, including after-hours or weekends if needed.
A full leakage assessment is recommended every 3 to 5 years. However, buildings with high occupancy, complex zoning, or IAQ-sensitive environments such as hospitals or labs may benefit from more frequent checks. Once sealed, ducts generally maintain airtightness unless disturbed by renovation, structural changes, or equipment replacement.
Sealing significantly reduces air loss by 90% or more in most systems. That leads to measurable improvements in airflow, temperature control, and energy use. Many of our Singapore clients report up to 30% savings on HVAC-related power consumption post-sealing, along with more balanced cooling across floors and zones.
No. Our process is isolated to the ductwork. After sealing, the pressure and airflow dynamics improve, which may reduce the load on your system. If required, we work with your BMS or mechanical consultant to re-balance airflow as part of post-sealing support.
Yes. We issue full leakage reports before and after sealing, including total airflow loss, leakage percentages, and sealing efficiency. These documents support NEA IAQ reviews, BCA Green Mark submissions, and internal ESG reporting. Safety data sheets and Aeroseal material certifications are also provided.
Yes. We understand the need to minimise downtime in commercial and institutional facilities. Delta Sirius offers flexible scheduling, including night shifts or weekend slots, so duct sealing doesn’t interfere with business operations. We also work with facility managers to align with BMS shutdown windows or maintenance cycles.
