Water Damage Restoration

Water damage restoration 

1. Class 1 water damage (least amount of water, absorption and evaporation): Water losses that affect only part of a room or area, or larger areas containing materials that have absorbed minimal moisture. Little or no wet carpet and/or cushion are present.

1. Class 2 water damage (large amount of water, absorption and evaporation): Water losses that affect at least an entire room or carpet and cushion(pad). Water has wicked up walls less than 24”. There is moisture remaining in structural materials (e.g., plywood, particleboard, structural wood, concrete).

1. Class 3 water damage (greatest amount of water, absorption and evaporation): Water wicked up over 24", or water may have come from overhead affecting ceilings, walls, insulation, carpet, cushion and sub-floor. The entire area are saturated.

1. Class 4 water damage (specialty drying situations): These consist of wet materials with very low permeance/porosity (hardwood, plaster, brick, concrete, stone). Typically, there are deep pockets of saturation, which requires very low specific humidity.

1. Category 1 is water from a clean or sanitary source. Previously known as clean water , this descriptor has since been removed to reduce confusion. These can include water from broken clean water supply lines; clean water from toilet tank or bowl; faucets; and bottled water. Although the source may be from a clean source, category 1 water can quickly degrade into category 2 or 3 depending upon such factors as time, temperature, and contact with contaminants.

1. Category 2 is water with some level of contaminants that could cause discomfort or illness if ingested. Previously known as grey water, this descriptor has since been removed to avoid confusion. Sources for category 2 water may include washing machine overflow; toilet overflow with some urine, but no feces; and dishwasher overflow. Category 2 water can quickly degrade into category 3 depending upon such factors as time, temperature, and contact with contaminants.

1. Category 3 water is grossly unsanitary, and could cause severe illness or death if ingested. Previously known as black water or black water, this descriptor has since been removed to avoid confusion. Sources for category 3 water include, but are not limited to, sewage; flooding from rivers or streams; wind-driven rain, water from beyond the toilet trap; water from the toilet bowl with feces; and standing water that has begun to support microbial growth.

Flood Drying and Water Mitigation

Structure and contents

When working within a residence, it is often the case that those who are performing the water damage restoration must work with and around the contents of the home. This includes, but is not limited to, furniture, electronics, books, and any other materials that may have been affected by the water damage. The moving around of the said contents is often referred to "contents manipulation." Water damage restoration firms often bill content manipulation on a per hour basis.

Contents may also require treatment due to the effects of water damage. This may include, but is not limited to, sterilization, sanitizing , deodorization, drying, and storage of said contents. Other contents may simply be non- salvageable, or the cost of having them salvaged would exceed its current value.

Monitoring

After the water has been extracted and any non-salvageable materials have been removed, water damage professionals should place drying equipment according to industry guidelines for capacity in the affected areas. Industry standards state that drying vendors should return to the residence at regular time intervals, preferably every twenty-four hours, to monitor the equipment, temperature, humidity, and moisture content of the affected walls, contents, or other affected materials. Should one area be dry and another affected area still wet, the firm will relocate or remove equipment accordingly.

Completion

Once temperature, humidity, and moisture content are deemed acceptable according to industry standards, drying equipment is removed and the drying process is complete. There are defining criteria and methods to be used for assessing water damage and establishing restoration procedures, but because of the unique circumstances of every water damage restoration project, it is impractical to issue blanket rules that apply to every situation. In extenuating circumstances, deviation from standard practices is appropriate.

Step-by-step process

Though the water seepage will stop once the source of water has been identified and plugged, the problem does not end there. It is essential to determine the appropriate water extraction method, which may range from the use of a wet-dry vac unit to more heavy duty equipment like submersible pumps. Once this has been completed, the process of drying and dehumidifier should start. Oftentimes, affected surfaces and areas look dry once the water has been extracted and removed, but there remains hidden water and moisture.This would call for the use of drying and dehumidifying equipment. As such, carpets, walls, and flooring require removal, drying, cleaning, and disinfecting.
