The process of repairing water damage is more complex than simply drying out the interior. With modern professional water damage remediation tactics, often restorers like Critical Control can mitigate damage which previously would have required complete structural replacement, in terms of demolition and rebuild.

Water Damage Restoration Guidelines are Available Contact a Professional

Many times, building or home owners try to tackle water damage using DIY solutions available online. This is not a good idea. There are guidelines for dealing with water damage and they require the skills and tools of experts. These guidelines are included in the IICRC Standard Reference Guide, or Professional Water Damage Restoration book. This guideline is essential to ensure that there is a professional standardisation for scenarios involving water damage structures or homes, as well as the risks associated with it.

Critical Control, a restoration firm, is able to use IICRC guidelines to help them determine the extent and type of the project’s damages.

These guidelines are important for professionals who deal with water damage. In some situations, an Indoor Environmental Professional (IEP) is essential. An IEP is an individual who has the skills and knowledge to assess an area for contamination collect samples, perform lab tests, then provide us with advice regarding the nature of the water damage.

This is crucial in cases where the building’s occupants are at high risk or are concerned about contamination.

Water damage according to categorizes and classes


Restoration projects for water damage are divided into two categories in accordance with the degree of the water infiltration is.

The class refers to how contaminated the water that entered the structure has been. Category 1 means that the water comes from a clean source such as a burst water supply or even a sink or tub.

Category 2 water is characterized by significant levels of contaminants and can cause illness if it is ingested or contacted. These sources can be waters that are not readily apparent as a risk like the discharge from washing machines or overflows from toilets.

Category 3 water is grossly affected, which means that it may have pathogenic, toxigenic or any other harmful agent within it. This could be due to backflows of sewage, toilet trap leaks, and floods of water from streams and rivers. The water could include heavy metals, pesticides or toxic substances.


The IICRC has also developed classes we use in determining the degree of water intrusion to your property. This system is basically a guideline for how much saturated a structure or house should be.

Class 1 refers to the lowest amount of absorption and the amount of water. It is the case when water comes into contact with less than 5% construction substances which absorb water. This is because the majority of substances that are affected by water won’t hold or absorb water. Examples include concrete, coated or finished wood, masonry or plaster.

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

Class 3 means that about 40% or more of the floor, wall and ceiling materials are porous materials such as carpet, insulation, fiberboard, etc. and where other materials that don’t absorb much water such as concrete or cement have not been adversely affected.

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

How to dry a water damaged Building or House


Three ways to remove water from buildings include physical extraction, dehumidification, and the process of evaporation. Eliminating liquid water is at most 500 times more effective than air movers. The quicker the structure is dried the more effective. The extraction method and the dehumidification process are affected by how much material is being removed.

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

Forced Evaporation

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

When an object is moistened or submerged in water it absorbs a portion of the moisture or water. The substance is then damp or wet as a result.

Saturation is the time at which it becomes impractical for air to hold any moisture. The greater the humidity, the more close the air is to being saturated.

The evaporation phase is when water molecules change from a liquid state to a gaseous form. The process is referred to as evaporation.

In other words it is does not absorb any more moisture from the air. We call that saturation point the point at which evaporation begins. Once saturation has been reached, the drying process begins.

In the evaporation stage, highly-efficient air movers dry the object from two sides. They generate a large airflow over the entire surface which is directed by a filter system that is able to cover the entire surface of the object.

An air mover can transport between 10 and 20% more air than a fan, or an ordinary fan in your home.

The item is dried by airmovers around 10 times faster than in the natural environment where no air mover was employed.

A high-velocity airflow is able to dry the surface of the object and draws in the moisture drawn away by the air mover.

Utilizing Heat to Aid the Drying Process

The element of heat is crucial to the success of any water damage restoration job. In order to dry out any materials that have been affected by water, we employ a number of different types of heaters.

Electric Heaters: These heaters may be used to dry jobs that require multiple heat sources. It is possible to run several heaters simultaneously because of their many wattages.

It is also possible to turn off or off electric heat as the work is done, without affecting other heaters. To increase efficiency and reduce your energy bills it is possible to adjust the wattage of a heater while increasing it’s capacity.

Electric heaters are a common feature in restoration work since they emit virtually no emissions and use minimal amounts of water. The only downside is that they take longer to heat up, requiring more time for the drying process generally.

Hydronic Bioler (TES),: The boilers quickly heat up and emit very little carbon dioxide. They can be powered by natural gas or propane.

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 using these kinds of heaters. They can also be used for dry work that does not require walls or ceilings to be able to stand in place.

Hydronic boilers are often used when there is no electrical power to power electric heaters. They can generate radiant heat and keep your drying area warm without the need of an electrical source.


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

The LGR Home Dehumidifier is capable of extracting 170 pints water from a damp building that is severely affected by water damage every all day, every hour of the day.

The dehumidifier in your home can remove water from the air in the same manner it does an LGR Refrigerant Dehumidifier. It can remove the 99 percent or more of airborne mold spores by removing condensation.

Fixing Wood Floor Water Damage

The floors that have been damaged by water need to be removed so that repairs can be made from the subflooring upwards.

The subflooring has to be taken off and repaired before. The affected hardwood floors require sanding down or replaced. To ensure uniformity, all floors should be sanded, then repaired after these repairs have been made.

Carpets are susceptible to water damage

If you have been unfortunate enough to have a flood in your home it could be a stressful and costly experience. You might need to change your flooring even if you’ve taken the water out of the area as fast as you can.

After investing time and money in restoring your home to its original state, it could be depressing to discover that the final results leave some things to be desired.

It is essential to assess the extent of the damage as fast as you can. One of the initial issues to address is whether or not the affected region should be replaced. There is a good chance that the carpet can be cleaned and still used after drying, and this cleaning can help to eliminate the concerns about mildew growth and persistent odors.

Salvaging Carpet After a Water Damage Event

If the water damage is severe, it is possible that you’ll see noticeable staining on your carpet. Sometimes, you will have to change your flooring to eliminate the stains. A strong, lingering odor may also be the reason to replace your carpeting. If this is the case then you may require replacement of both the padding and carpet.

When the firm has finished their task, you’ll be capable of making an informed decision about the condition of your carpeting and decide whether or not you need to replace it.

Water Damaged Drywall

The degree of damage will determine the kind and method of drywall repair. Repairing water damage may be as easy as taking out the drywall portion and cleaning the area and then replacing it.

The other side is that major damage could need to be repaired completely, including the wall studs and fiberglass insulation.

The spores of mold can be seen in drywall damaged by water that is difficult to eliminate. In most instances drywalls will have to be replaced. We use moisture testing tools to measure the amount of the moisture. This helps us 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 contract. It is easier to break wood if it is moistened by water. If the water is left to sit for a lengthy time, there can be an abundance of rot within the wood that can make it break easily.


This problem can be avoided by building owners and homeowners making immediate changes to repair structural damage from moisture-related issues with their property after flooding or other water-related damage.

Foundation Water Damage

There are a variety of reasons that water damage can affect a foundation of a house. While not every water issue cause structural damage, it is important to correct foundational problems as quickly as you can to prevent future structural damage.

Water damage to the foundation can result in a myriad of problems depending on how it’s treated. If the damage is not addressed promptly, it could result in serious structural damages.
