Basement Drying and Dehumidification in Syracuse

How do you know a basement is dry?

A basement is dry when the readings at the floor, the wall base, the framing and the air reach a dry level and stay there across visits. A surface that feels dry is not treated as dry, because the moisture may be underneath it.

The crew uses a moisture meter on the concrete, the wood and the drywall, and it takes a reading at several heights on each wall. The air's humidity is read with the temperature to show how much moisture it can still take up. The readings are logged with their locations, so the next visit can compare them directly.

A single reading does not show that the drying is complete. The drying is complete when the readings have been dry on two visits in a row at every measured point, which is the only way to be sure the moisture is not returning from a deeper source.

What does a dehumidifier do that fans cannot?

Air movers speed the evaporation of water from surfaces, while a dehumidifier removes water from the air. A basement needs both, because air movers alone can push humidity into the rest of the house.

Air movers blow air across the surface so the water evaporates faster. The moisture then sits in the air of the room. Without a dehumidifier to remove it, the room becomes humid, and the humid air slows the drying and can add moisture to dry materials.

A dehumidifier pulls moisture out of the air and holds it in a tank or sends it out through a drain. The combined use of air movers and a dehumidifier keeps the drying steady, and the crew sets both by the readings for the room.

Why does a Syracuse basement wall need its base opened?

A wall base often holds water after the floor looks dry, because the moisture moves up the drywall and into the cavity. Opening the base lets the air reach the cavity and the framing behind it.

Drywall wicks water up from the floor, and the paper facing holds it. The moisture then fills the space behind the board, where the air cannot reach it without an opening. A cavity that is closed up wet can keep the framing damp for weeks and support mold growth.

The crew cuts a section a short distance above the highest reading and checks the cavity with a meter. The opening is kept as small as the readings allow, and it is closed up only after the cavity reads dry.

• Cut above the highest wet reading on the wall
• Check the cavity and the framing with a meter
• Dry the cavity with targeted airflow
• Close the opening only after the readings are dry

How long does basement drying take?

Basement drying usually takes several visits over a number of days, depending on how deep the moisture went and how many openings are needed. The drying time is set by the readings, not by a fixed schedule.

A shallow wet floor with no wall damage may dry in a few days. A basement where the water tracked up the walls and into the sill can take longer, because the framing and the concrete release moisture slowly. The crew explains the expected timing on site after the first readings are taken.

Drying can seem finished before it is. The crew does not stop until the readings are dry, and it may return one more time after the rest of the work is done to confirm that the moisture has not come back.

What should the owner keep from the drying?

Keep the readings log, the photographs of the water line and the list of openings made. Those records show the drying was completed and what was done to the walls.

The log shows the readings at each visit and the equipment placed. The photographs show the state of the room before and after each opening, which helps when the walls are rebuilt and when the insurer asks about the work.

Keep the invoices and the scope with the log. A dated, complete record makes it easier to answer a buyer's or an insurer's questions about a basement that was flooded.
