Water Damage Restoration Guidelines are available Contact a Professional

Many times, building or home owners attempt to address water damage by using DIY solutions that can be found online. This is not a good idea. The management of water damage is according to established guidelines. These guidelines require the knowledge and skills 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 for professional standardisation of situations that involve water damage to buildings and homes and the risks they pose.

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

These guidelines are crucial for professionals dealing with water damage. In certain situations there are situations where an Indoor Environmental Professional (IEP) is essential. An IEP is someone who has the skills and knowledge to assess an area for contamination collect samples, perform lab tests and offer us suggestions on the nature of the water damage.

This is especially important in cases where the building’s inhabitants could be at risk, there is a likelihood of adverse health effects, the occupants have a desire to know the suspected contaminants or have another reason that there might be concerns about contamination.

Water damage through categorizes and classes


Restoration of water damage projects are classified according to category and class based on the severity of the flooding of water.

The water entering the building was classified according to the degree of contamination. Category 1 water originates from a clean source like a tub or sink or a burst water supply.

Category 2 involves water that has significant levels of contaminants and is likely to cause illness or discomfort if contacted or consumed. These sources can be waters that are not readily apparent as a danger like the discharge from washing machines and spills from toilets.

Water in the category 3 is severely contaminated meaning that it can contain toxic, pathogenic or other harmful substances in it. This usually means contamination from the backflow of toilets from the toilet trap and seawater, flooding from rivers and streams or any other source of water that comes from the building exterior. This kind of water could have pesticides, heavy metals that are regulated, toxic materials, or chemicals in it.


The IICRC has also created classes to follow when determining the level of water intrusion to your property. The system basically serves as a guideline for how saturated a building or home ought to be.

The lowest level of water absorption , and the most water is classified as Class 1. It is the case when water is in contact with less than 5% of the building materials which absorb water. This is due to the fact that most of the substances affected by water do not absorb or hold water. Examples are concrete, finished/coated wood, plaster or masonry.

Class 2 means that there is a significant infiltration of water as well as intrusion. It is approximately 10% up to 40% of the total ceiling, floor and wall consist of low evaporation materials such as plaster, wood, concrete, or the masonry.

Class 3 refers to the fact that around 40% or more of the wall, floor and ceiling materials are porous materials such as fiberboard, insulation, carpet and so on. Other materials such as cement or plaster that don’t absorb water haven’t been adversely affected.

The water has been absorbed into materials such as concrete, plaster, and wood, which are classified as Class 4. This requires special drying techniques and longer drying times.

How to Dry a Water damaged building or house


Physical extraction, dehumidification and evaporation are the three main methods to remove water from a structure. Eliminating water from liquids is typically 500 times more efficient than using dehumidifiers or air movers. The quicker the structure dries the more efficient. The quantity of material to be extracted can affect the extraction process as well as dehumidification methods.

Professionals dealing with water damage employ various extraction methods. We employ a range of tools , including self-propelled and subsurface extraction tools.

Forcible Evaporation

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

When an object is moistened or submerged in water, it absorbs some of the moisture or water. In the process, the material becomes dampened or wet.

Saturation is the time at which it becomes impractical for air to hold any moisture. The greater the humidity, the closer the air is getting to saturation.

In the evaporation phase the water molecules leap from a liquid state to a gaseous state. This process is known as evaporation.

In other words it is no longer absorbs additional moisture from the air. This is known as the saturation point. When saturation is attained the drying process commences.

High-efficiency air movers dry objects in two areas in the evaporation phase. They produce a powerful airflow over the surface of the object that is controlled by a filter that completely covers the area of the object.

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

Air movers dry the object approximately 10 times faster than in natural conditions, where no air mover is used.

A high-velocity airflow dries the surface and absorbs the moisture taken away by the air movement.

Utilizing Heat To Aid In the Drying Process

Heat is an important component of any water damage restoration project. We employ a variety of heaters to dry materials that have been damaged by water.

Electric Heaters They are ideal to dry jobs that require the use of multiple heat sources. They come in a variety of wattages, allowing you to operate multiple heaters at once.

Electric heat is also capable of being shut off or reduced while the job is in process, without affecting your other heaters. To increase efficiency and reduce your energy bills you can alter the wattage of a heater and increase its wattage.

Because they emit almost no emissions and require very minimal water Electric heaters are popular for restoration projects. However, the only drawback is that they take longer time to warm up, which means that they require longer drying time. process generally.

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

Hydronic boilers are different from electric heating in that they do not make use of forced air to distribute heat, so it can be challenging to evenly heat a large area with these types of heaters. They also run at a lower temperature, making them ideal for drying jobs which require ceilings and walls to remain in place.

Hydronic boilers are also often employed when there isn’t enough electrical power to power electric heaters. Because they are so efficient at producing radiant heat, they are able to easily keep your drying space warm even without an electric power source.


We utilize Low Grain Refrigerant Dehumidifiers (LGR) to keep buildings dry and houses that have suffered water damage.

The LGR Home Dehumidifier is capable of removing 170 pints water from a damp structure which has been badly damaged by water damage each 24 hours.

The home dehumidifier can extract water from the air in the same manner as an LGR Refrigerant Dehumidifier. It can also get rid of up to 99 percent of the mold spores that are airborne through the elimination of condensation.

Repairing Hardwood Floor Water Damage

Hardwood floors damaged by water have to be cut up to ensure repairs can take place from the subflooring upwards.

Drywall that has been damaged by water

The severity of the damage determines the kind and way to repair drywall. Repairing water damage may be as easy as removing the drywall portion and then cleaning the affected area and then putting it back.

The opposite of this is that significant damage may require a complete replacement of the wall, which includes fiberglass insulation and wall studs.

There are spores of mold in damaged drywall, which is difficult to remove. In the majority of cases, the drywall will have to be replaced. We employ moisture testing tools which allow us to identify how large and where the moisture has become. This allows us to identify damaged areas and limit the cost to only the areas that are damaged.

Water can also cause structural damage since it causes the wood to expand or contract. When the wood is saturated with water, it’s much more difficult to break. The wood can be brittle if allowed to dry in water for too long.


This problem can be avoided by homeowners and building owners immediately taking action to repair the structural damage caused by moisture-related issues with their property after a flood or other water-related damage.

Foundation Water Damage

The damage caused by water to a house’s foundation can occur for many reasons. While not all issues with water cause structural damage, it’s critical to repair foundational problems as quickly as possible to avoid structural damage.

The damage caused by water in the foundation could cause various issues in the manner it is handled. 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 catastrophes. In addition to creating roof leaks damage can also cause issues with the walls and foundations of a the building.

Leaking roofs are extremely costly and might have significant drawbacks. A leak in the roof can result in mold and mildew to grow, which can be deadly. A leaking roof may also cause damage to the roof truss system that can lead to structural damage to the roof.

Leaks from the ceiling could cause your rafters to deteriorate and soften if you do not take action immediately. Electrical faults are also prevalent in roof water damage, that can lead to the possibility of an electrical fire. All of these are good reasons to get roof water damage repaired quickly after a flood or other sudden damage.

HVAC Water Damage
