The most common cause of water damage is when water gets into a structure or home by way of a flood, storm, or ruptured pipe. Sometimes the damage is evident and apparent. In other instances, it’s subtle or under-reported.

Water Damage Restoration Guidelines are readily available Contact an Professional

A lot of times, homeowners or builders attempt to repair water damage using DIY solutions that can be discovered online. This is a bad idea. Water damage can be managed in accordance with the established guidelines. These guidelines call for the knowledge and skills of professionals. These guidelines are included in the IICRC Standard Reference Guide, or Professional Water Damage Restoration book. This guide is created because of the need for professional standardisation of situations that involve water destruction to buildings and homes as well as the risk they present.

Critical Control, a restoration company, can use the IICRC guidelines to assess the type and extent of the project’s damages.

These guidelines are essential for professionals who deal with water damage. In certain circumstances, an Indoor Environmental Professional (IEP) is required. An IEP is an individual who has the skills and experience to analyze a site for contamination collect samples, perform lab tests and provide us with advice regarding the nature of the water damage.

This is particularly important in cases where the building’s residents are at high risk or there is concern regarding contamination.

Water damages caused through categories and classes


Restoration projects for water damage are classified by category and class based on the severity of the invasion of water.

The classification refers to how contaminated the water that enters the structure is. The first category is water that is clean such as a tub or sink or a burst water supply.

Category 2 water has high levels of contaminants and could cause illness if it is inhaled or touched. These include sources that are not usually considered to be a threat such as discharges from washing machines, or overflows from toilets.

Category 3 water can be considered to be extremely polluted. It could be contaminated by toxic, pathogenic or any other dangerous substances. Usually this means contamination from the backflow of toilets from the trap for toilets and seawater, flooding from rivers and streams or any other water arising from the exterior of the building. This water may be contaminated by pesticides, heavy metals or toxic substances.


The IICRC has also created classes we use in measuring the amount of water intrusion into your property. The system basically serves as an indication of the amount of water a building or residence ought to be.

The lowest level of water absorption , and the greatest amount of water is categorized as Class 1. It is the case when water comes in contact with around 5% or less with construction materials which absorb water. This is because most materials that are affected by water won’t hold or absorb water. Concrete, plaster, masonry, and finished/coated wood are just a few examples.

Class 2 refers to water absorption and intrusion. It means that anywhere between 5 and 40% of the floor, ceiling and wall is constructed of low-evaporation materials like plaster, concrete, wood, or the masonry.

Class 3 means that about 40 percent or more of floor, wall and ceiling surfaces are porous materials like fiberboard, insulation, carpet and so on. and where other materials that don’t absorb much water such as plaster or concrete have not been negatively affected.

Class 4 refers to the fact that water has become deeply bound in materials that do not easily absorb water like concrete, wood, and bricks and mortar. This is why special drying methods are required and longer drying time.

How to dry a water damaged building or house


Three methods for removing water from buildings include physical extraction, dehumidification and evaporation. Eliminating liquid water is at most 500 times more efficient than dehumidifiers and airmovers. The faster the structure dries the more effective. The extraction method and the dehumidification process are affected by how much of the material is extracted.

Water damage professionals use a variety methods. We employ a range of tools , including subsurface extraction tools and self-propelled tools.

Forcible Evaporation

After the water is removed, the remaining moisture is dried using high-velocity airmovers.

If an object is wet or submerged in water, it absorbs some of the water or moisture. In the process, the object becomes damp or wet.

The saturation level is referred to as the point at which it is impossible to hold any more moisture. The greater the humidity, the closer the air is to saturation.

In the evaporation phase, water molecules jump from a liquid state to a gaseous state. This is referred to as evaporation.

This signifies that the object has stopped absorbing water from the air. This is called the saturation point. Once the saturation point is reached drying begins.

In the evaporation stage, highly-efficient air moves dry the object on two sides. They generate a large air flow over the surface of the object, that is controlled through a filter system that is able to cover the entire area of the object.

A fan that moves air can move 10 to 20 times more air than a fan or an ordinary household fan.

Air movers dry the object about 10 times faster than in normal conditions, when there isn’t any air mover.

Airflows with high velocity dry the surface and absorbs the moisture pulled out by the air movement.

Using Heat To Assist the Drying Process

The element of heat is crucial to the success of any restoration project. To dry out the materials that have been affected by water, we make use of various kinds of heaters.

Electric Heaters: Electric heaters are great for drying jobs that require multiple heating sources. They come in a variety of energies, which lets you use multiple heaters at the same time.

Electric heat can also be able to be turned down or off during the process, without affecting your other heaters. This means that you could reduce one heater while increasing the power of the other to increase efficiency, and decrease your energy costs.

Because they emit virtually no emissions and require very less water, electric heaters are very popular in restoration projects. They are more difficult to heat up and require longer drying time.

Hydronic Bioler (TES): Hydronic boilers are also very efficient in heating up quickly and generating very little emissions. They can be run on propane or natural gas.

Hydronic boilers differ from electric heating in that they don’t use forced-air to distribute heat, so it can be difficult to evenly heat a large area using these kinds of heaters. They can also be utilized to dry jobs that do not require ceilings or walls to be able to stand in their place.

If electric heaters are not employed, hydronic boilers may typically be utilized. Because they are extremely efficient in producing radiant heat they are able to keep your drying area warm even when there is no electrical power source.


To dry houses and buildings that are damaged due to water damage, we employ Low Grain Refrigerant (LGR) Dehumidifiers.

The LGR Home Dehumidifier can draw 170 pints of moisture from damp structures that have experienced severe water damage within 24 hours.

The home dehumidifier can extract water from the air the same way it does an LGR Refrigerant Dehumidifier. It can get rid of the 99 percent or more of the mold spores that are airborne by removing condensation.

Fixing Wood Floor Water Damage

It is important to remove flooring that has been damaged by water to ensure that repairs can be made starting from the subflooring.

Drywall that has been damaged by water

The process for repairing drywall varies based on the extent of the damage. Repairing water damage is as simple as removing an area of drywall, cleaning it, and after that, replacing it.

The other side is that serious damage could require a complete replacement of the wall, which includes fiberglass insulation and wall studs.

The drywall that is damaged by water usually harbors mold spores that cannot be easily removed. In most instances drywalls will have to be replaced. We employ moisture testing tools that help us determine the extent to which water has grown. This allows us to identify areas that are damaged and limit costs to those areas that are only damaged.

Water can also cause structural damage, since it causes the wood to expand or expand or contract. When the wood is saturated with water, it’s much easier to break. If the water remains for a lengthy time, there could be an extensive amount of rot on the wood that can cause it to break easily.
