Remediation is not just removal. A job that does not find and fix the moisture source is a job that gets done twice. A typical visit moves through inspection, containment, removal, and addressing whatever is keeping the area damp - though not every company includes all four by default.
The four stages
Each stage is a separate piece of work, and it is worth knowing which ones a given quote covers.
Inspection
1- Confirms the extent of visible growth and, where possible, identifies the moisture source behind it
Some companies offer this as a free first step; others fold it into the overall quote.
Containment
1- Seals off the affected area with plastic sheeting and negative air pressure so spores do not spread while work is underway
This matters more on larger jobs and in occupied homes than on a small, isolated patch.
Removal
1- Material that cannot be cleaned - drywall, some insulation, porous flooring - is removed and disposed of rather than treated in place
What gets removed versus cleaned in place depends on the material and how far the growth has spread into it.
Moisture-source repair
1- The leak, the ventilation gap, or the drainage problem gets fixed
This is the stage most likely to be quoted separately - ask directly whether it is included.
What happens after the work is done
Some companies include a post-work check to confirm the area is clear before calling the job finished; others consider the job done once visible material is removed. Asking which approach a company takes - and what happens if the same spot returns - is a reasonable question before you book, not an unusual one.
