Every dryer vent service includes an inspection of the dryer venting system before & after the cleaning.  This is performed with the use of an internal camera inspection system to ensure that there are no visible issues within your venting system. It also gives us eyes within your dryer vent to be sure the system has been thoroughly cleaned. Other methods of inspection include the use of a Vane Anemometer which allows us to measure airflow through the dryer exhaust duct & the use of a Magnehelic Gage which allows us to measure resistance or back-pressure in the dryer exhaust.
