Precautions to Protect Our Customer's Property

To deliver the best and safest service possible, the 3 Pros team takes extra precautions when working on-site to ensure that our customer's property is well-protected. Some added precautions we take include laying tarp over the driveway to prevent any debris from collecting on it and using fans and layflat ducting to push air out of the work space. This creates negative pressure so that dust is contained in the work space and does not get into upper levels of the property.
