Water Damage Restoration Guidelines are Available – Call a Professional

Many times, homeowners and builders attempt to repair water damage with DIY solutions discovered on the internet. This is not a good idea. There are guidelines to deal with water damage and they call on the equipment and expertise of experts. These guidelines are found in the IICRC Standard Reference Guide, or Professional Water Damage Restoration book. This guide is required to ensure the professional standardisation of scenarios involving water damage houses or buildings, and the risks associated with it.

The IICRC guidelines assist restoration professionals like Critical Control to evaluate the category and class of damage on each project.

These guidelines are important for water damage professionals. There are instances that require our bringing in the services of an Indoor Environmental Professional (IEP). An IEP is an individual with the knowledge and knowledge to assess the condition of a place, take samples, run lab tests, then provide us with advice regarding the kind of water damage that is likely to occur.

This is especially important in situations where the occupants of the building could be at risk, there are a chance of adverse health effects, the occupants have a desire to know the contaminants that are suspected, or some other reason for concern over contamination.

Categories and Classes of Water Damage


Restoration of water damage projects are classified according to category and class, based on the degree of invasion of water.

The class refers to how polluted the water that entered the structure is. Category 1 implies that the water comes from a clean source such as burst water supply, or even a sink or tub.

Category 2 water contains significant levels of contaminants and can cause illness if it is inhaled or touched. These include sources that are not usually considered to be dangers, such as the discharges from washing machines, or toilet overflows.

Category 3 water can be classified as highly contaminated. It could be contaminated by toxic, pathogenic or other hazardous substances. This usually means contamination by the backflow of toilets from the toilet trap or a flood of seawater from rivers and streams, or any other water flowing from the building exterior. This category of water can contain heavy metals, pesticides and regulated substances as well as toxic substances within it.


The IICRC has also developed classes we use in determining the degree of water intrusion on your property. This is basically an indication of the amount of water a building or home ought to be.

The lowest amount of absorption by water and the greatest amount of water is categorized as Class 1. This is the case when water comes in contact with less than 5% of construction materials which absorb water. This is due to the fact that most of the materials that are affected by water do not hold or absorb water. Concrete and masonry, as well as plaster and wood that has been finished/coated are some of the examples.

Class 2 refers to water absorption and intrusion. This is about 5 to 40% of the combined floor, wall and ceiling are composed of low evaporation materials like plaster, concrete, wood, or bricks and mortar.

Class 3 is the term used to describe 40% or more of the wall, floor and ceiling materials are porous materials like carpet, insulation, fiberboard, etc. and also where other materials that do not absorb much water such as plaster or concrete have not been adversely affected.

The water has been absorbed into materials such as concrete or plaster and wood that are classified as Class 4. This is why special drying methods are required and longer drying times.

How to Dry a Water Damaged Building or Home Building Works


Physical extraction, dehumidification and evaporation are three methods to remove water from a structure. Eliminating liquid water is, at a minimum, 500 times more effective than air movers. The quicker the structure dries the better. The quantity of materials to be extracted can affect the extraction process as well as dehumidification methods.

Water damage experts utilize a variety of extraction methods. We use a variety of equipment, such as subsurface extraction tools and self-propelled tools.

Forced Evaporation

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

Submerged objects absorb water and moisture when it is moistened. In the process, the material gets dampened or wet.

The saturation level is described as the point where it is impossible to hold any additional moisture. The higher the humidity, the closer the air is to saturation.

The evaporation process occurs the moment when water molecules shift from the state of liquid to a gaseous one. This is referred to as the process of evaporation.

This signifies that the object has stopped absorbing water from the air. This is known as the saturation point. When saturation is reached, drying will begin.

In the evaporation phase high-efficiency air movers dry the object from two sides. They generate a large airflow across the entire surface which is directed by a filter system that is able to cover the entire surface of the object.

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

The item is dried using airmovers about 10 times faster than natural conditions where there was no air movement.

The high-speed airflow dry the surface and absorbs the moisture that has been taken away by the air movers.

Utilize heat to aid in the drying process.

The most important element for any water damage restoration work is heat. To dry out materials that have been affected by water, we employ a number of different types of heaters.

Electric Heating Equipment: These heaters can be used for drying jobs which require multiple sources of heat. 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 done, and not affect other heaters. In order to maximize efficiency and lower the cost of energy, you can adjust the power of one heater, while also increasing its power.

Electric heaters are very common in restoration work because they produce essentially zero emissions and consume only a small amount of water. They require longer to warm up and need longer drying time.

Hydronic Bioler (TES) These boilers are extremely efficient in heating up quickly, while still producing low emissions. They can be run on natural gas or propane.

Hydronic boilers differ from electric heat since they don’t utilize forced air heat to disperse heat. This can make it difficult to distribute heat evenly over large areas by using these heaters. They are also able to dry jobs that do not require ceilings or walls to remain in their place.

Hydronic boilers are also often used when there is no electricity to run electric heaters. They are capable of producing radiant heat, and they can keep your drying area warm without the requirement of an electric source.


To dry buildings and houses that have been damaged by water damage, we make use of Low Grain Refrigerant (LGR) Dehumidifiers.

The LGR Home Dehumidifier is capable of extracting 170 pints of water in a damp structure that has been severely affected by water damage each 24 hours.

In addition to removing water from the air, as a LGR Refrigerant Dehumidifier does it, the dehumidifier for your home will also eliminate up to 99% of airborne mold spores the air, by removing condensation.

Repairing Hardwood Floor Water Damage

The floors that have been damaged by water need to be cut up to ensure repairs can take place beginning with the subflooring and moving upwards.

The damaged subflooring first needs to be taken off and fixed. The affected hardwood floors require sanding down or replaced. Once these repairs are complete then the entire floor must be sanded and refinished to ensure a uniform appearance.

Carpets are susceptible to water damage

Floods can cause serious damages to your house and can make repairs difficult and expensive. Even if water is removed from the affected area immediately, there is an opportunity that you’ll need to replace your flooring eventually.

After spending time and money to restore your home to its pre-flood condition, it would be devastating to find that the finished results leave some things to be desired.

It is essential to assess the extent of the damage as fast as you can. The first thing to do is to determine if the damaged area needs to be replaced. There is a good possibility that the carpet could be cleaned and used after drying, and this cleaning will help eliminate some of the worries about the growth of mildew and persistent odors.

Salvaging Carpet After a Water Damage Event

If the damage from water is severe there is a chance that you’ll notice staining on your carpet. Sometimes, you will have to change your flooring to get rid of these stains. An odor that is persistent and strong may also be the reason to get your carpet replaced. It is necessary to change your carpet and padding in the event of this.

Check to see if the floor can be professionally dried before you decide to repair it or replace it. If you can have a reliable company do the cleaning, then you’ll have a better understanding of how serious the damage was. Our company will assess the carpet and decide whether it is best to replace it or repairable. Remember that certain methods employed for drying may harm the carpet further if it is already in poor condition.

The main factors which will decide whether or not the carpet and padding require replacement are:

Can your carpets be dried or cleaned professionally?

If the padding under your carpet is damaged, it can impact how long the carpet is clean. Although your carpet has been dried quickly, mildew growth may still be present in the padding beneath if it isn’t dried.

The best way to be sure that your carpeting is properly restored and disinfected after an event of flooding is to engage a professional carpet cleaning company. Once the company has completed their work, you will be able to make a more informed decision about the condition of your carpet and decide whether or not you need to replace it.

Drywall Damaged by Water

The procedure for repair of drywall differs depending on the severity of the damage. Repairing water damage can be simple as taking out an area of drywall then cleaning it and then replacing it.

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

Water damaged drywall often harbors mold spores that can’t be easily removed. In the majority of cases the drywall will need to be replaced. We use moisture testing tools to assess the extent of the moisture. This allows us to pinpoint damaged areas and limit costs to the only damaged ones.

The water can also cause structural damage, as it causes the wood material to expand and expand and contract. It is much more difficult to break wood when it has been moistened with water. If the water is left to sit for a prolonged time, it could cause a significant amount of rot on the wood that can cause it to crack easily.


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

Water Damage in the Foundation

Water damage to a house’s foundation can occur for a number of reasons. While not every water issue can lead to structural damage, it’s important to fix foundational problems as quickly as you can to avoid future structural damage.

Water damage to the foundation can result in a myriad of problems based on how it is dealt with. If the damage is not taken care of quickly, it could result in serious structural damages.


Roof Water Damage

Water damage to roofs can be caused by natural catastrophes as well as foundation water damage. As well as the possibility of roof leaks, roof damage can cause problems with the walls and foundation of a home or construction.

Leaking roofs are extremely costly and can have significant drawbacks. Roof leaks can lead to mold growth and can be fatal. A leaky roof can harm the roof truss system that can lead to structural damage to the roof.

Leaks in your ceiling could cause your rafters to decay and soften if you do not address them immediately. Electrical problems are also common when it comes to roof water damage which could cause the possibility of an electrical fire. All of these are good reasons to get roof water damage fixed quickly following a flood or other sudden damage.

HVAC Water Damage

If your HVAC system starts to fail or brand new equipment becomes defective, it could cause structural damage to your home. Your business and home at risk by not having HVAC. It is possible for mold to grow and cause a variety of health issues that are very serious.

Damage to the Pipe Water

What’s the price to restore the water damage?

Water damage restoration cost per square foot

Based on the square foot, water damage repairs and cleanup expenses differ. The following pricing breakdown can be obtained at National Flood Services for each square foot

Is water damage covered by homeowners’ insurance?

If the cause of the damage was unintentional and sudden, homeowners insurance policies generally cover it. According to the Insurance Information Institute, homeowners insurance can cover repairs or replacement for a damaged window, however, not if the damage occurs as a result of neglect.

Damage caused by neglect can be defined as wear and tear of an object or surface due to exposure, insufficient preventative maintenance, or general degradation. The Insurance Information Institute in the US states that homeowners insurance does not cover the damage caused by negligence.

A homeowners policy would not cover water damage caused by flooding. The flood insurance policy is mandatory. Mortgage lenders might need flood insurance in specific areas. Flooding may occur because of storms, ground that is saturated to the point of overflowing or surging bodies of water like rivers, ponds, lakes, streams, oceans in combination with high winds.
