What we cover
Basements flood from one of three sources: failed sump pump (inside source), groundwater intrusion (storm/runoff outside source), or sewer backup (Category 3 black water).
The source determines everything: scope of work, demolition required, sanitization protocol, and final cost. A clean-water sump-pump failure is a Category 1 event. A sewer backup is Category 3 and triples the cost.
Our first action is determining the source. Then we pump, extract, demolish what won't dry, sanitize if Category 2 or 3, and set up drying.
Basements are challenging for drying because of poor air circulation and high humidity at the foundation level. We bring desiccant dehumidifiers (better than refrigerant for cold environments) and high-CFM air movers.
