Duct Sealing

At TLS Insulation, we provide professional duct sealing services to help you improve the efficiency and performance of your HVAC system. Our duct sealing process involves using advanced technology and materials to seal any leaks or gaps in your ductwork, preventing conditioned air from escaping and reducing energy waste. By sealing your ducts, you can improve indoor air quality, reduce energy bills, and enhance overall comfort.

What is Duct Sealing?

Duct sealing is the process of making the air duct system airtight. In many homes, especially older ones, ductwork that distributes air from your heating and cooling system into your rooms may have leaks, holes, or poorly connected segments.

This can lead to significant energy loss, as heated or cooled air escapes into unconditioned spaces like attics, crawl spaces, or even outside your home.

How Do We Conduct Duct Sealings?

After you’ve called us at (833)-857-7283 and received your free quote we’ll get started.

Step 1: Initial Consultation and Inspection


Our process begins with a consultation to discuss your specific needs and concerns. Whether you’re experiencing uneven cooling, higher than expected energy bills, or concerns about indoor air quality, we tailor our approach to address these issues effectively.

Our trained technicians conduct a detailed inspection of your duct system using advanced diagnostic tools. We look for signs of leaks, holes, and disconnected ducts, particularly in hard-to-reach areas like attics, crawl spaces, and behind walls.

Step 2: Duct Sealing Process

Before starting the sealing process, we prepare the area to ensure that your property remains clean and undamaged. This includes covering floors, furniture, and other surfaces as necessary.

Sealing Leaks:

We use industry-leading methods and materials to seal your ductwork. This typically involves applying mastic sealant or metal tape to all joints, seams, and any visible holes. Mastic sealant is a durable, flexible material that forms an airtight seal, effectively preventing air from leaking out.

Advanced Sealing Techniques:

For larger gaps or areas where traditional materials are less effective, we may use aerosol-based sealant systems. This method involves blocking the registers and blowing sealant through the duct system, where it seeks out and seals leaks from the inside, which is particularly useful for inaccessible parts of the ductwork.

Step 3: Testing and Verification

After sealing the ducts, we conduct a post-seal test to measure the effectiveness of our work. Using tools like a duct blaster, we can quantify the reduction in air leakage to ensure that the sealing meets industry standards for efficiency and performance.

Review and Adjustments:

We review the results with you and make any necessary adjustments. Our goal is to ensure that your duct system is as efficient as possible, providing maximum comfort and energy savings.

Duct Sealing Questions:

Duct sealing offers several key benefits including improved energy efficiency, which can significantly reduce your heating and cooling costs. It also enhances indoor air quality by preventing dust, insulation particles, and other contaminants from entering the duct system and circulating through your home. Additionally, duct sealing helps maintain consistent temperatures throughout the house, eliminating hot and cold spots for more uniform comfort.

Sealing leaky ducts can lead to substantial energy savings, typically ranging from 20% to 30% of your heating and cooling costs. The exact savings can vary based on factors like the extent of the leaks, the age of your HVAC system, and your local climate, but duct sealing is generally one of the most cost-effective ways to improve energy efficiency in a home.

Even new homes can benefit from duct sealing. Building processes are not perfect, and small gaps and leaks are common in ductwork. Having new ducts sealed can ensure that they operate at peak efficiency from the start, preventing common issues that can develop over time from initial minor leaks.

When done professionally, duct sealing is a durable solution that can last as long as the ductwork itself, typically several decades. The longevity of duct sealing depends on the materials used and the conditions within the ductwork, such as humidity and temperature variations.

Yes, duct sealing can significantly improve the performance of your HVAC system by ensuring that air is not lost as it travels through the ductwork. This not only helps the system heat or cool your home more effectively but also reduces the strain on the HVAC equipment, potentially extending its lifespan and reducing maintenance needs.

Absolutely. By sealing leaks in ductwork, you can prevent outdoor pollutants, dust, and pests from entering the duct system and spreading throughout your home. This is particularly beneficial for individuals with allergies or respiratory conditions, as it helps to maintain a cleaner and healthier indoor environment.
