Fitchburg has a humid continental climate, with warm, rainy summers and cold, snowy winters, and both seasons change how a wet building dries.
How drying is planned and measured
The crew first maps the wet area and classes the loss from small to severe, then sizes air movers and dehumidifiers to the volume of the space. A reading from an unaffected room becomes the goal for every wet material, so the finish is measured and never guessed. Loss classes run from small, quick drying jobs to Class 4 jobs, where moisture sits deep in dense materials such as hardwood, plaster and masonry, and the class decides how much equipment the crew sets.
- Air movers push dry air across wet surfaces and into cavities
- LGR and desiccant dehumidifiers pull the moisture out of the air
- Cavity drying vents wall bottoms and floor systems
- Daily readings on the same spots show what is dropping
