CMR air duct cleaning company specializes in mold remediation in residential, industrial, and commercial HVAC systems and air ducts in the greater Raleigh area.
The first thing we do when we tackle a mold remediation job is do a good inspection of the system. We have to locate the source of the problem and fix it. Mold thrives in moist, humid conditions so we have to find how moisture is getting into the system and stop it from happening.
Once we have the problem fixed then we have to determine where the mold is present. Here’s the thing when you have mold in the HVAC system. We can treat and remediate the microbial growth if it is on a hard surface. However, it is a different problems when it is on a porous surface like insulation or duct liner.
The first exposed layer may be successful but you can treat it when it is say an inch deep in the material. In situations like this we strongly recommend for it to be replaced. Now there are certain situations where this may not be cost effective or even possible. So in a circumstance like this we will clean it with Microban and then encapsulate the air duct.
There are a lot of different products out there. The encapsulating agent is applied by either a roller, brush, or airless paint sprayer. The encapsulating agent will applied in the air duct and form a egg shell like covering in the duct work. This locks down all the fibers and will prevent mold from returning. Some of the manufactures will give a 2 year warranty the mold will not come back.
Large commercial projects like hospitals, schools and other high profile jobs are now making this a mandatory step in the HVAC restoration process. The National Air Duct Cleaners Association has a lot of good information on this topic as well. We are members of the association.
In the pictures below you can see a before and after picture. In the first you can see visible mold on the duct work, in the second a white encapsulating agent has been applied.
