Working drying calculators
Psychrometry, initial dehumidifier load, and air-mover placement — aligned to IICRC S500 field methods. Type in real numbers and get an answer.
Compare two air masses in grains per pound (GPP). Effective drying needs the dehumidifier’s exhaust drier than the room — a positive GPP depression.
Starting estimates aligned to IICRC S500 methods. Always verify against on-site psychrometric readings, moisture mapping, and the drying plan.
How water gets into a home
The four intrusion paths that turn into claims — see each one happen, then trace where the water actually goes. It rarely shows up where it got in.
Roof & attic. A failed shingle, valley, or vent flashing lets water into the attic. It tracks down the rafters and top plate, then follows the wall cavity to the floor below — often surfacing far from the actual leak.
Flashing details — one lap makes or breaks it
The most common hidden leak on a building envelope. Flip between a correct lap and a reverse lap to see why the order of the layers is everything.
Reverse lap. The flashing up-leg is placed over the WRB, so water running down the barrier slips behind the flashing, into the sheathing and down to the interior sill — a hidden leak that rots framing and grows mold before anyone sees a stain.
This knowledge, built into the software
RestoredOS runs the whole job — drying logs, moisture mapping, scope, budget, and billing — on the same field knowledge behind these tools.
