THE AEROSEAL PROCESS

The Most Effective Duct Sealing Solution

Process1At ECS, we don’t just seal your ductwork… we aeroseal it! Old fashioned sealing – with tape or mastic – only works if you can reach the leaks and seal it by hand. Even then, ensuring the entire leak is sealed can be iffy at best. The results only last for a limited time.Aeroseal seals leaks from the inside of the ductwork. That means it can easily find and seal ALL the leaks – even those hidden behind walls, under insulation or other hard-to reach places. The computer-controlled process ensures that the leaks are completely sealed and time-elapsed testing shows that leaks sealed with Aeroseal can last the life of your home. Here’s how we do it.
IMG_2421sThe Aeroseal duct sealing process begins when we temporarily block the registers of your home by taping over the grill or removing the grills and placing foam inserts into openings. Then we connect a large flexible tube from our computer-controlled aeroseal deliver system to your ductwork. Now that the registers are blocked, any air being blown from our tubing into your ductwork has only way way to escape…through the leaks in your ductwork. So before we even start the sealing process, we blow air into your system and the computer tells us right away how much air you are losing through leaks. Once we have a “before” picture of your leakage rate, we begin the sealing process, sending the microscopic particles of sealant throughout the inside of the duct system. The mist of sealant stays suspended in air until it comes to a leak. Here the particles cling to the edge of the leak and then to other sealant particles, bonding to each other until the entire leak is sealed.DSC_5243sAeroseal does not coat the entire inside of the ductwork but instead, accumulates around the edges of the leaks. The sealant itself dries immediately and is completely non-toxic. In fact, it has been used in some of the most prestigious hospitals and laboratories throughout the world. You won’t even need to leave home during the sealing process. During the process itself, the computerized sealing system continues to monitor the progress. A visual graph shows the rate of leakage in real time, allowing you to actually watch as the leaks seal and the amount of escaping air is reduced.
CertificateAt the end of the sealing process, we will print out and give you a report that documents the results. You’ll have a detailed analysis of your duct system’s leakage rate before we began and then the final leakage rate. It will tell you the percentage of reduced leakage and calculate the equivalent hole size that the combined leaks represent.
