Water Damage Restoration Guidelines are in place and you can call a Professional

A lot of times, property or home owners attempt to deal with water damage by using DIY solutions that can be found on the internet. This is not advisable. There are guidelines to deal with water damage , and they call on the equipment and expertise of experts. The guidelines are laid out in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide is created because of the need for professional standardisation of situations that involve water damage to buildings and homes as well as the risk they create.

Critical Control, a restoration business, can use IICRC guidelines to evaluate the severity and nature of the project’s damages.

There are many reasons why professionals dealing with water damage must follow these guidelines. In certain situations it is necessary to employ the use of an Indoor Environmental Professional (IEP) is required. An IEP is someone with the knowledge and training to evaluate an area for contamination collect samples, perform lab tests, then offer us suggestions on the kind of water damage that is likely to occur.

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

Water damage according to types and classes


Restoration projects for water damage are classified into two categories, depending on how extensive the water infiltration is.

The class has to do with how polluted the water that enters the structure has been. Category 1 is water that comes from a clean source like the sink or tub, or burst water supply.

Category 2 water is characterized by significant levels of contaminants and can cause illness when it is ingested or contacted. It could include sources that might not appear to be dangers, such as 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 toilet backflows following the trap for toilets or a flood of seawater from rivers and streams, or any other water arising from the building exterior. This kind of water could contain heavy metals, pesticides and regulated substances as well as toxic substances within it.


The IICRC has also created classes that we follow in measuring the amount of water intrusion to your property. The system basically serves as an outline of how saturated a building or house is.

The lowest degree of absorption by water and the greatest amount of water is categorized as Class 1. This is when the water is in contact with around five percent or less construction materials which absorb water. This is usually the case in which the majority of substances affected by water have low evaporation. This means they do not absorb or hold in water. Examples are concrete, finished/coated wood, plaster or masonry.

Class 2 means that there is significant absorption of water and intrusion. This is about 10% up to 40% of the combined ceiling, floor, and wall consist of low evaporation materials like plaster, wood, concrete, or masonry.

The porous materials like fiberboard, insulation and carpet which make up Class 3 comprise around 40 percent of wall, floor and ceiling materials, with about 40% in class 3. Other materials, such as concrete and plaster that do not absorb water haven’t been affected in any way.

The water has been absorbed into materials like concrete, plaster, and wood, which are classified as Class 4. This means that it requires longer drying times and special drying methods.

How Drying a Water Damaged home or Building Works


Three ways to remove water from buildings are physical extraction, dehumidification, and evaporate. Eliminating liquid water is at most 500 times more effective than using dehumidifiers or airmovers. The quicker the structure dries the more efficient. Both methods of extraction and dehumidification are affected by how much of the material is extracted.

Professionals dealing with water damage employ an array of extraction techniques. We employ a range of equipment, such as subsurface extraction tools and self-propelled tools.

Forcible Evaporation

The remaining moisture is dried using high-speed air movers once the maximum amount of water has been taken away.

A submerged object absorbs water and moisture once it’s moistened. The substance gets wet or damp due to this.

Saturation is the time where it becomes unachievable for the air to contain any moisture. The greater the humidity, the closer the air is to being saturated.

The evaporation phase is the time when water molecules transition from a liquid state to a gaseous form. This process is known as evaporation.

In this way it is will no longer absorb additional moisture from the atmosphere. This is called the saturation point. As soon as saturation is reached, the drying process begins.

In the process of evaporation the highly efficient air mover dry the object from two sides. They generate strong airflow that is directed by a filter system.

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

Air movers dry the object approximately 10 times faster than in the natural environment, in which there isn’t any air mover.

A high-velocity airflow is able to dry the surface of the object and sucks up the water that was taken out by the air movement.

Utilizing Heat to Aid The Drying Process

The element of heat is crucial to the success of any water damage restoration task. We employ a variety of heaters to dry materials that are damaged by water.

Electric Heaters: Electric heaters are great for drying tasks which require the use of various heating sources. You can run multiple heaters simultaneously due to their many wattages.

Electric heat is also adjustable, allowing it to be reduced or turned off during the process, without impacting your other heaters. This means you can reduce one heater while increasing the wattage of the other to increase efficiency and reduce your cost of energy.

Because they emit almost zero emissions and consume very minimal water Electric heaters are used in restoration projects. However, the only drawback is that they take longer to heat up, requiring more time to dry process overall.

Hydronic Bioler (TES) Hydronic boilers are also very efficient in heating up quickly yet releasing very little emissions. They typically operate using propane or natural gas.

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

In the event that electric heaters can’t be utilized, hydronic boilers can typically be utilized. They are capable of producing radiant heat and keep your drying space warm without the need for an electrical source.


We use low Grain Refrigerant Dehumidifiers (LGR) to help dry out buildings and houses that have suffered water damage.

The LGR Home Dehumidifier can remove 170 pints of moisture from damp structures which have suffered extensive water damage within 24 hours.

The dehumidifier at home is able to remove water from the air in the same manner as an LGR Refrigerant Dehumidifier. It can get rid of the 99 percent or more of the mold spores that are airborne through the elimination of condensation.

Repairing Wood Floor Water Damage

It is essential to take away water damaged hardwood floors to allow repairs to be done starting from the subflooring.

A variety of factors can determine the need for padding or carpet is a good idea to replace it.

  • How much water did you get on your carpet?
  • How long was the amount of water that sat on the carpet?
  • Quelle was the source water?

Are your carpets dry or cleaned professionally?

The carpet’s ability to stay fresh can be compromised if the padding beneath it has been damaged. Although your carpet has been dried in a short time, mildew growth may still be present in the padding beneath if it isn’t dried.

Professional carpet cleaning company is the most effective way to ensure that your carpet is dry and clean following a flood. After the company completes their work, you will be in a position to make an informed decision regarding the condition of your carpet and decide whether or not you need to change it.

Drywall damaged by water

The severity of the damage determines the type and method of drywall repair. Repairing water damage may be as simple as removing some drywall and cleaning the area and replacing it.

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

Drywall that has been damaged by water often contains mold spores that can’t be easily removed. In most cases, the drywall will have to be replaced. We utilize moisture testing tools to measure the amount of moisture. This allows us to pinpoint areas that are damaged and limit costs to the only damaged ones.

Water can also cause structural damage, since it causes the wood to expand or expand or contract. Once the wood is moistened by water, it becomes much more difficult to break. The wood may become brittle if it is allowed to dry in water for too long.


To avoid this problem, it’s essential for building owners and homeowners to fix structural damage from water-related issues with their home immediately following an event like a flood or water damage incident.

Water Damage in the Foundation

Water damage to the foundation can trigger a number of different issues dependent on the way it is dealt with. If the problem isn’t addressed quickly, it can cause serious structural damage.


Roof Water Damage

As with foundation water damage roof water damage is fairly common after natural disasters. Roof damage could cause roof leaks, and can also cause damage to the foundation of a house or house.

Leaking roofs can be extremely costly and can have significant negatives. Leakage in the roof could lead to mold growth and can be fatal. A roof that is leaky could cause damage to the roof truss system, which can cause structural damage to the roof.

Leaks in your ceiling could cause your rafters’ to degrade and become soft if you don’t take action immediately. Roof water damage can also result from electrical faults which could lead to an electric fire. These are all good reasons to have roof water damage dealt with quickly after a flood or any other unexpected damage.

Are water damages covered by homeowners’ insurance?

Homeowners insurance policies are usually applicable if the source of the damage is unexpected and unintentional. According to the Insurance Information Institute, homeowners insurance policies can cover repair or replacement for a broken window, however, not if the damage occurs as a result of negligence.

Neglect can be described as damage to a surface or an object that is caused by the weather, lack of maintenance or general wear and tear. The Insurance Information Institute in the United States states that homeowners insurance does not cover damage caused by neglect.

If the water damage is the result of a flood, the event would not be covered by a homeowners policy. A flood policy would be required. In some regions, flood policies are required by mortgage companies. Flooding may occur due to flooding, over-saturated ground, overflowing or surging bodies of water such as rivers, ponds, lakes oceans, streams together with high winds.
