Structural drying in Uptown and Edgewater

The ceiling of one unit and the floor of the next are one assembly. Drying one side leaves moisture trapped. A single plan covers every wet unit from the fire floor to the basement, with access arranged for units whose residents are away.

Plaster and old hardwood dry slowly. Controlled dehumidification and gentle warmth protect them from cracking and splitting. Daily readings guide adjustments ^[1].

Basements and garden units collect the water. Finished walls come out so masonry can dry. The boiler room is checked before heat is restored.

In towers, water sits on concrete slabs under flooring. Flooring is often lifted so the slab can dry; leaving it traps moisture for weeks.

If the central boiler is off in winter, temporary heat or desiccant dehumidifiers keep drying going while the plumbing is protected.

When walls must be opened in pre-1978 buildings, lead-safe practices apply ^[4].

Equipment runs only from circuits confirmed safe, or temporary power, coordinated with the building.

Check closets and basements a few weeks later. EPA advises professional help for larger mold areas ^[2].

Daily readings and photos help the building's insurer and each household's insurer ^[5].

In a six-flat, water from the top floor on one side soaks the floor assemblies down that side to the basement. Equipment goes into each wet unit and the basement at once. Plaster ceilings in the lower units are checked for sagging and drained if needed. The central stair, if water ran down it, is dried too.

Readings are taken daily in plaster, wood and masonry, and equipment is moved as areas reach their dry standard.

In a courtyard building, water usually stays within the affected entry's stack. Drying covers those units and the shared basement. Units in other entries are checked to confirm they stayed dry.

Furniture against wet walls blocks airflow. Belongings are moved to the center of rooms, raised on blocks or packed out. Wet papers and photos are dried or frozen.

Ask how they set dry standards for plaster, wood and masonry, how often readings are taken, whether every wet unit is on one plan, and how equipment will be powered safely. Ask for the daily log in writing.

Day one: extraction, removal of wet finishes and setup in every wet unit. Then daily readings and adjustments, with equipment concentrated where readings stay high. Plaster and masonry usually set the pace.

Drying equipment draws a lot of power. In a building where the fire affected the electrical system, equipment runs only from circuits an electrician has confirmed safe or from temporary power. Coordinate with the owner and management, especially when equipment runs in several units at once.

A few weeks after equipment leaves, check closets on exterior walls, under sinks and the basement. A musty smell suggests moisture stayed somewhere. EPA advises fixing moisture problems and drying quickly, and professional cleanup for larger areas ^[2].

Keep the moisture map, readings and photos. They show insurers the building was dried properly and answer questions from future buyers or inspectors about past water damage.

Many older units have hardwood strip floors over plank subfloors on wood joists. Water from above soaks all three layers. Floor drying mats pull moisture up through the boards while dehumidifiers dry the air. Refinishing waits until boards, subfloor and joists all read normal, or the floor will move again after sanding.

Removing baseboards lets air reach the bottom of the wall and the floor edge, where water collects. Small holes behind the baseboard line let dry air into the wall cavity without large openings. Baseboards can usually be reinstalled afterward.
