What Kinds of Tools Are Used in Duct Sealing?

One of the great misunderstandings of home repairs is that “duct tape” is useful for repairing broken ducts. But duct tape is essentially worthless for this job, although it can help in hundreds of other ways for household chores. This misconception of the purpose of duct tape goes back to the 1950s, when what was until then called “duck tape” received a deceptive new name.

When it comes to sealing ducts, you need to rely on professionals who use a set of special tools for the job that are out of the reach of most consumers. Sealing ducts doesn’t only involve special tools, but also special training. If you require duct sealing in Waldick, NJ, call up only trained technicians to handle it. The indoor air quality experts at DB Heating & Cooling will bring the best tools and top-quality training to the job of sealing your leaky ventilation system.

The tools used in professional air duct sealing

  • Leak detectors: A key part of the process of sealing ducts is to locate where the leaks are. The technicians turn on the HVAC system to send air through the ductwork and use detectors that contain a fan and a pressure sensor to track down where the ducts are losing pressure and how large the leaks are. This will give the technicians a good idea of how much work needs to be done and what sort of methods will work. (For example, in cases of extreme leaks, they may suggest replacing sections of the ducts.)
  • Mastic sealant: Mastic is a resin-based sealant which technicians apply to gaps and leaks using a caulking gun. Mastic will stick to most surfaces and remain flexible even after it dries, making it resistant to breaking when the gaps expand and contract during temperature changes. It also keeps a smooth surface to offer little resistance to airflow.
  • Metallic tape: This is true “duct tape,” metal foil used to create actual mechanical seals along damaged ducts. Some technicians prefer these tapes to mastic sealant because they have an even higher durability to temperature changes and do not age as rapidly. However, whether a duct sealer uses metallic tape of sealant to fix a leak will usually depend on the size and location of the gap. Skilled technicians will know the right method for each situation.
