After we take out all the wet stuff, we build a great big containment. Why do we build a containment? To protect the exposed wood! We don't want more damage to occur after removing wet materials. We use special materials to cover and protect all the areas that were exposed to water. It also helps us when we proceed with the reconstruction phase. We like to work as neatly as possible and the containment makes the work space look and feel organized. It also helps keep dust out! It makes the area look neat and organized. That's exactly how we like our jobs to look. Most customers appreciate when we leave the containment up, it helps the construction phase run smoothly. Containments are effective for us to finish a job quicker.
