Water Damage Restoration Guidelines Exist – So Call an Professional

Many times, homeowners or builders try to fix water damage using DIY solutions that can be located on the internet. This is not advisable. Water damage can be controlled in accordance with established guidelines. These guidelines demand the skills and tools of experts. These guidelines are detailed in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. The guide was created due to the necessity of professional standardisation in situations involving water damage to buildings and homes and the risks they pose.

The IICRC guidelines aid restoration experts like Critical Control to evaluate the category and class of damages on every project.

There are many reasons why professionals dealing with water damage must adhere to these guidelines. There are certain situations that require our bringing in an Indoor Environmental Professional (IEP). An IEP is a professional who has the training to assess the condition of a place take samples, perform laboratory tests, and help us determine the kind of water damage.

This is particularly important in situations where the building’s occupants are at high risk or have concerns about contamination.

Categories and classes of Water Damage


Projects for water damage restoration can be classified into two types according to the extent of the infiltration of water is.

The water that entered the building was classified based on its level of contamination. Category 1 water is clean such as a tub or sink or a burst water supply.

Category 2 involves water that has significant levels of contaminants, and could be able to cause discomfort of illness should it be consumed or ingested. It could include sources that are not usually considered to be an issue, like the discharges from washing machines, or toilet overflows.

The water in the category 3 is considered extremely contaminated. It could be contaminated by pathogenic, toxic, or other dangerous substances. Usually this means contamination by the backflow of toilets from the toilet trap or a flood of seawater from rivers and streams, or any other source of water that comes from the exterior of the building. This kind of water could include heavy metals, pesticides and regulated substances as well as toxic substances within it.


It is also possible to use the IICRC’s classes to determine how much water has gotten into your property. This is basically setting guidelines for the level of saturation of the building or home.

Class 1 means the least amount of absorption and the amount of water. This is when water is in contact with less than 5% of the building materials that absorb water. This is because most materials that are affected by water won’t absorb or hold water. Concrete or plaster, masonry and wood that has been finished/coated are a few examples.

Class 2 signifies that there is significant infiltration of water as well as intrusion. It’s about 5 to 40% of the combined floor, wall and ceiling consist of low evaporation materials such as plaster, wood, concrete or masonry.

Class 3 refers to the fact that around 40% or more of the floor, wall and ceiling materials are porous like carpet, insulation, fiberboard, etc. and where other materials that do not absorb water like concrete or cement have not been adversely affected.

Class 4 refers to the fact that water has become deeply trapped in the materials that can not easily absorb water like concrete, wood, and masonry. This means that it requires longer drying times and special drying methods.

How to Dry a Water Damaged House or Building


Three ways of removing water from buildings include physical extraction, dehumidification and evaporate. Removal of liquid water is at minimum 500 times more efficient than merely making do with dehumidifiers and air movers. The faster the structure dries the more effective. Both extraction and dehumidification methods are affected by how much of the material is extracted.

Water damage professionals use different extraction techniques. Some of our tools include tools for subsurface extraction, wands Self-propelled tools, self-propelled instruments, and vacuum squeegees.

Forced Evaporation

The remainder of the moisture gets dried with high-velocity air movers after as much water as is taken away.

A submerged object absorbs moisture and water when it’s moistened. As a result, the material becomes dampened or wet.

The degree of saturation is known as the point where it is impossible to hold any more moisture. Higher humidity means that the air is closer to saturation.

The evaporation process occurs the time when water molecules transition from a liquid state to a gaseous one. The process is referred to as evaporation.

This means that the object has stopped absorbing moisture from the air. The saturation point is the point at which evaporation begins. When saturation is attained, the drying process begins.

High-efficiency airmovers dry the object in two areas during the evaporation phase. They create a strong airflow over the surface of the object which is directed by a filter that completely covers the area of the object.

An air mover can move between 10 and 20% more air than a fan, or a standard household fan.

Air movers dry objects about 10 times more quickly than the natural environment, in which no air mover is used.

Airflows that are high-velocity leaves the surface dry and absorbs moisture pulled out by the airflow.

Use heat to assist the drying process

The most important element of any restoration project is heating. To dry out the materials which have been affected by water, we employ a number of different types of heaters.

Electric Heating Equipment: These heaters can be used to dry jobs which require multiple sources of heat. This is because they come in a variety of wattages, allowing you to run multiple heaters simultaneously.

It is also possible to turn off the electric heating while the job is being completed, but without impacting other heaters. This means that you can lower one heater, while increasing the wattage of the other to increase efficiency, and decrease your expenses for energy.

Because they emit virtually zero emissions and consume very less water Electric heaters are used for restoration projects. They take longer to warm up and need longer drying time.

Hydronic Bioler (TES): Hydronic boilers are also very efficient in heating up quickly, while still producing low emissions. They are typically run on natural gas or propane.

Hydronic boilers are different from electric heat since they don’t utilize forced air heat to spread heat. This makes it difficult to distribute heat evenly over large areas with these heaters. They can also be utilized to dry jobs that do not require walls or ceilings to be in the same place.

In the event that electric heaters can’t be used, hydronic boilers can typically be utilized. They can produce radiant heat, and they can keep your drying space warm without the need of an electric source.


To keep buildings and homes dry which have suffered damage due to flooding, we employ Low Grain Refrigerant (LGR) Dehumidifiers.

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

Apart from removing water out of the air like an LGR Refrigerant Dehumidifier does this, the home dehumidifier can also get rid of up to 99percent of airborne mold spores in the air by eliminating condensation.

Fixing Wood Floor Water Damage

It is important to remove water damaged hardwood floors to allow repairs to be done by removing the subflooring.

Professionals can assist you in determining how severe the damage was. We can assess whether your carpet needs to be replaced or can be saved. Be aware that some of the techniques employed for drying may harm the carpet further even if it’s already in bad condition.

Several factors will influence the need for padding or carpet need to be replaced.

Do your carpets need to be dried and cleaned, or disinfected and cleaned professionally?

The carpet’s capacity to remain clean can be affected if the padding beneath it is damaged. Although your carpet has been dried in a short time, mildew growth may still be present when the padding beneath is not dried.

The safest way to ensure that your carpet is restored and disinfected after an event of flooding is to engage an expert carpet cleaning service. Once the cleaning is complete, you’ll be able make an informed decision on the condition of your carpeting. It is also possible to decide whether to replace it.

Drywall that has been damaged by water

The process for repairing drywall varies depending on the severity of damage. Repairing water damage can be as easy as taking out a portion of drywall and then cleaning the affected area and then putting it back.

The opposite of this is that major damage could require whole-wall replacement including walls studs and fiberglass insulation.

Mold spores can be found in drywall damaged by water that is hard to get rid of. Most of the time, the drywall will have to be replaced. We employ moisture testing tools that allow us to determine the extent to which water has grown. This allows us to pinpoint damaged areas and limit costs to those areas that are only damaged.

It also causes structural damage, as it causes the wood to expand and expand and contract. It is easier to break wood if it has been moistened with water. If the water remains for a long period of time, there can be an extensive amount of rot within the wood, which could cause it to crack easily.


This issue can be prevented by owners of buildings and homeowners taking immediate action to fix structural damage from moisture-related issues with their property after an event like a flood or damages caused by water.

What is the price of cleaning up water damaged?

Water damage restoration cost per square foot

Cleaning and repair cost will differ based on how many square feet you have. The following pricing breakdown is available at National Flood Services for each square foot

Are water damages covered by homeowners’ insurance?

The homeowner’s insurance policies are generally applicable if the source of the damage is sudden and unintentional. The Insurance Information Institute states that homeowners insurance can cover the repair or replacement of windows that have been damaged, but not for damage caused by negligence.

Neglect is defined as damage to a surface or an object that is the result of exposure, poor maintenance or general wear and tear. The Insurance Information Institute in the US states that homeowners insurance does NOT cover neglect-related damage.

A homeowner’s policy does not cover water damage caused by flooding. Flood insurance is mandatory. In some areas the flood policies are demanded by mortgage companies. Flooding can happen due to floods, storms, overflowing bodies of water, or overflowing or surging bodies such as rivers, lakes, streams and oceans.
