Structural Drying >> Ceiling Leak Repair Cost

If the water level was less than 2½ feet, the wall material should be removed to a height of 4 feet to facilitate reinstallation of full sheets of drywall. If the water level was greater than 2½ feet, the wall material should be removed to a height of 8 feet or the ceiling junction, whichever is higher. Electrical outlet and wall switch plates and door Ceiling Leak Repair Cost and window moldings must be removed prior to the tear out of the wall material.

Fibrous wall insulation (fiberglass, mineral wool, cellulose, wood fiberboard, etc.) saturated by floodwater should be removed completely. Foam plastic insulation may be left in place and allowed to dry.Flooded electrical receptacles should be removed completely after the appropriate circuit breakers Ceiling Leak Repair Cost or fuses are deactivated.

Wall paneling should be removed if it is swollen or if saturated drywall is behind the paneling.4. Clean OutFollowing any necessary tear out, clean up any remaining debris Ceiling Leak Repair Cost and muck. Squeegees, shovels, and brooms are effective for such cleaning. Personal protective equipment should be utilized. Detailed cleaning and sanitizing of the remaining materials should be conducted. 

A shop vacuum with dry filters in place and with a solution of clean water and disinfectant in the tank (2-inch depth) to minimize the spread of dust can be used.Mold removal. Treatment with commercial mold removers does eliminate visible evidence of mold growth on exposed surfaces Ceiling Leak Repair Cost and is recommended for restoring flood-damaged homes. 

Tests have found very little or Ceiling Leak Repair Cost no evidence of mold growth in the non-exposed (hidden) portions of the walls. Treating the non-exposed portions of the walls for mold control does not appear warranted in most cases. Spraying vertical surfaces using a compression (pump-up) garden sprayer with a commercial mildew remover is recommended. Understand the limitations of bleach. 

While this material is convenient and appropriate as a sanitizer for hard, non-porous items after they have been cleaned, it has distinct drawbacks when cleaning flood-impacted buildings. Application of bleach water can cause corrosion of electrical components Ceiling Leak Repair Cost and other metal parts of mechanical systems, and can compromise the effectiveness of termite treatments in the soil surrounding the building. 

Its effectiveness at killing bacteria and mold is significantly reduced when it comes in contact with residual dirt. Moldy surfaces should be cleaned first Ceiling Leak Repair Cost and then disinfected. Residual mold spores should then be removed, since killing them does not reduce their toxicity.Remove mud and gross contamination from floors by shoveling into suitable containers. Reduce soil and contaminant levels on surfaces by flushing off with clear water. 

The fastest and most efficient method to clean Ceiling Leak Repair Cost and decontaminate materials and surfaces is by using a residential-type pressure washer to apply a cleaner-disinfectant solution to the affected areas (Figure 2). Brushes improve decontamination of floors and some walls by scrubbing solution into affected surfaces. 

Avoid scrubbing drywall and plaster walls at this time because they have become softened by the flooding and moisture and may have their surface damaged by scrubbing. Following the first cleaning, floors and walls should be rinsed with water Ceiling Leak Repair Cost and the cleaning process redone a second time. Squeegees can be used to control or direct spent solution, and wet vacuums can be used to collect spent solution.

Using a pressure washer to clean contaminated surfaces.

Dry Out Once the clean process is completed, the building and any remaining contents need to dry. 

Drying is a naturally occurring process. Over time, Ceiling Leak Repair Cost all wetted building materials will dry. Drying of structural materials will take an extended period of time to dry to pre-flood conditions. Exterior rooms with excellent ventilation can take 2 to 4 weeks to dry, depending on the temperature and humidity outside. 

Interior rooms, or those with minimal ventilation, can take 4 to 6 weeks or more to dry Ceiling Leak Repair Cost and are candidates for the use of mechanical drying equipment. The use of fans, dehumidifiers, air conditioners, and/or auxiliary electric heaters will speed drying. Allowing materials to dry naturally will take considerably longer.

Wood framing. The moisture content of wood framing must be checked professionally Ceiling Leak Repair Cost or with a commercially available moisture meter before refinishing or recovering so that excessive moisture does not become trapped in the materials and cause future problems (Figures 3a and 3b). Dryness of wood framing materials can be determined quantitatively using the table on the right above. 

Wetted materials are presumed dry when their moisture content readings are less than or equal to 15 percent when taken with an intrusive/penetrating moisture meter (Figure 3a). If an intrusive/penetrating moisture meter is not available, Ceiling Leak Repair Cost a non-intrusive/penetrating moisture meter (Figure 3b) may be used; however, keep in mind that the material moisture results measured from non-intrusive meters may be less accurate than intrusive meters.

Summary of Moisture Reading Results for Wood Framing MaterialsMoisture Reading: >20%, Results: Wet – no goodMoisture Reading: 15-20%, Results: Partially dry – caution Ceiling Leak Repair Cost Moisture Reading: <15%, Results: Dry – OK[End table]Figure 3a caption.

The moisture content of drywall (gypsum board), plywood floors, Ceiling Leak Repair Cost and other building materials must also be checked professionally or with a commercially available moisture meter before refinishing or recovering so that excessive moisture does not become trapped in the materials and cause future problems.

Unlike wood framing, Ceiling Leak Repair Cost the dryness of other building materials must be confirmed qualitatively by comparing readings between like materials in affected areas of the building (at or below flood level) and unaffected areas of the building (a room or upper floor above the flood level, or inside a nearby building that was not flooded). 

Wetted materials are presumed dry when their Ceiling Leak Repair Cost moisture content readings are within 5 percent of those of like materials in unaffected areas of the building when taken with an intrusive/penetrating moisture meter (Figure 3a).
