* Water-damage basis: locate every affected material with moisture meters and other industry standard procedures, extract standing water fast, and use advanced drying equipment to bring humidity back to normal.
* Mold that can follow water damage: identify the moisture source feeding it, fully contain the affected area with negative air pressure to prevent cross contamination, and eliminate the mold using the highest industry standards, then fix the moisture problem so it does not come back.
* Water damage is stated to get worse by the hour, with water wicking up walls, soaking into subfloors, and creating conditions for mold within 24 to 48 hours.
* Biohazard and rebuild scope: biohazard cleanup, sanitizing, and complete rebuilds handled by the same team that dries the home.
* Asbestos testing and abatement is listed as available during repairs as part of the same engagement.
