Water Damage Restoration Guidelines Exist so call a Professional

A lot of times, property or home owners attempt to address water damage using DIY solutions found on the internet. This is a bad idea. There are guidelines for dealing with water damage and they require the skills and tools of professionals. The guidelines are set forth in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. The guide was created due to the necessity of professional standardisation of situations that involve water damage to buildings and homes as well as the risk they pose.

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

These guidelines are crucial for water damage professionals. There are certain situations that require our bringing in the services of an Indoor Environmental Professional (IEP). An IEP is professional with the experience and knowledge to examine the health of a building, collect samples, get laboratory tests, and advise us on the category of water damage.

This is particularly important in cases where the building’s residents are at risk or have concerns about contamination.

Categories and Classes of Water Damage


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

The water entering the building was classified according to its level of contamination. Category 1 means that the water is from a clean source such as burst water supply, or a sink or tub.

Category 2 water is characterized by significant levels of contaminants and can cause illness when it is inhaled or touched. These sources can be water that isn’t obvious as a risk like the discharge from washing machines or spills from toilets.

Category 3 water is grossly polluted, meaning it could have pathogenic, toxigenic or any other harmful agent in it. This usually means contamination by the backflow of toilets from the toilet trap and seawater, flooding from rivers and streams, or any other water flowing from the exterior of the building. This category of water can contain heavy metals, pesticides and regulated substances as well as toxic chemicals in it.


The IICRC has also established classes to follow when determining the degree of water intrusion to your property. The system is basically a set of guidelines for the saturation of the structure or the home.

Class 1 refers to the lowest amount of water and absorption. This happens the case when water comes in contact with less than 5% of building materials which absorb water. This is because the majority of substances affected by water do not absorb or hold water. Concrete, finished/coated wood, plaster or masonry.

Class 2 is a term used to describe water absorption and intrusion. It means that anywhere between 5% to 40% of the total ceiling, floor and wall is constructed of low-evaporation materials like plaster, concrete, wood or bricks and mortar.

Class 3 refers to the fact that around 40 percent or more of floor, wall, and ceiling surfaces are porous materials like carpet, insulation, fiberboard, etc. Other materials, such as cement or plaster that don’t absorb water have not been affected in any way.

Class 4 indicates that water has been deeply stuck in materials that do not easily absorb water like plaster, wood, concrete and bricks and mortar. This calls for special drying techniques and longer drying time.

How do you dry a water damaged home or Building Works


Physical extraction, dehumidification, and evaporation are the three main methods of removing water from buildings. The elimination of water that is liquid is at about 500 times more efficient than simply putting up with dehumidifiers and air mover. The faster the structure can dry, the more efficient. Both methods of extraction and dehumidification are affected by how much material is being removed.

Water damage experts employ various extraction methods. Some of our tools include subsurface tools, wands, self-propelled tools, and vacuum squeegees.

Forced Evaporation

Once all water has been removed, any moisture remaining is dried with high-speed airmovers.

Submerged objects absorb water and moisture when it’s moistened. The substance becomes damp or wet because of this.

The degree of saturation is referred to as the point at which it is impossible to hold any more moisture. The greater the humidity, the closer the air is to being saturated.

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

In this way, the object no longer absorbs additional water from the atmosphere. This is known as the saturation point. the point at which evaporation begins. When saturation is reached the drying process starts.

High-efficiency air movers dry the object in two areas during the evaporation process. They create a strong airflow over the entire surface, that is controlled by a filter that is able to cover the entire area of the object.

A fan that moves air can move around 10 to 20% more air than a fan, or an ordinary fan used in the home.

The item is dried by airmovers around 10 times faster that in natural conditions where no air mover was employed.

The high-speed airflow dry the surface of the object and absorbs the moisture that has been drawn out by the air mover.

Using Heat To Assist The Drying Process

Heating is a crucial element of any water damage restoration project. In order to dry out any materials that have been affected by water, we make use of a number of different types of heaters.

Electric Heaters They are ideal to dry jobs that require several different heating sources. They come in a variety of power levels, which allows you to use multiple heaters at the same time.

It is also possible to turn off or off electric heat when the task is completed, but without impacting other heaters. This means that you could lower one heater, while increasing the wattage of another to maximize efficiency and reduce your energy costs.

Electric heaters are common in restoration projects since they emit virtually no emissions and use minimal amounts of water. The only issue is that they take longer to heat up, requiring longer drying time. process in general.

Hydronic Bioler (TES) Hydronic Bioler (TES), These boilers are able to heat quickly and emit very little carbon dioxide. They typically operate using propane or natural gas.

Hydronic boilers are different from electric heat as they don’t make use of forced-air heat to spread heat. This makes it difficult to heat large areas evenly with these heaters. They are also able for dry work that does not require walls or ceilings to be able to stand in place.

Hydronic boilers are often employed when there isn’t enough electrical power to power electric heaters. They are capable of producing radiant heat and keep your drying space warm without the requirement of an electric source.


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

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

The dehumidifier in your home can remove 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 Wood Floor Water Damage

It is crucial to get rid of flooring that has been damaged by water to allow repairs to be completed starting from the subflooring.

The subflooring must be removed and repaired first. Then the affected hardwood boards must be sanded or replaced. After these repairs are completed, the entire floor should be sanded and refinished to guarantee a uniform appearance.

It would be devastating to discover that your home isn’t in the best condition after spending so much time and money to repair it.

It is crucial to determine the extent of damage as soon as is possible. One of the first things that must be resolved is whether or not the damaged area should be replaced. There is a way to clean the carpet, then use it once dry. This will eliminate any worries about the growth of mildew or persistent smells.

Salvaging Carpet After a Water Damage Event

You may notice stains on your carpet if the water damage was very extensive. In some cases, you may need to replace your flooring to eliminate the stains. Another aspect that may prompt you to think of replacing your carpet is the persistent and strong scent. If it is, then you will likely require replacement of both the padding and carpet.

Be aware that some methods used for drying can also harm the carpet further even if it’s already in poor condition.

Several factors will influence the need for padding or carpet is a good idea to replace it.

Do your carpets get professionally cleaned, dried and disinfected?

The carpet’s ability to remain clean can be affected if the padding beneath it has been damaged. Although your carpet may have dried quickly, mildew growth may still be present when the padding beneath is not dried.

Professional carpet cleaning service is the best way to make sure your carpeting is clean and dry after the flood. After the job is completed you’ll be able to make an informed decision about the state of your carpet. It is also possible to decide whether to replace it.

Drywall that has been damaged by water

The degree of damage will determine the nature and way to repair drywall. Repairing water damage can be as easy as removing some drywall, cleaning the area, and then putting it back.

The flip side of the coin is that significant damage may need to be repaired completely, including walls studs and fiberglass insulation.

Drywall that has been damaged by water often contains mold spores that can’t be removed easily. In most instances drywalls will have to be replaced. We employ moisture testing tools that help us determine where and how extensive the water has grown. This allows us to isolate the areas that are damaged and limit the costs to areas that need to be repaired.

It also causes structural damage by causing the material to expand and shrink. After the wood has been moistened by water, it becomes much easier to break. The wood can be brittle if allowed to dry in water for too long.


This problem can be avoided by owners of buildings and homeowners immediately taking action to repair the structural damage caused by moisture-related issues that affect their property after flooding or other water-related damage.

Water Damage to the Foundation

Water damage to a house’s foundation can happen due to many reasons. While not all issues with water cause structural damage, it is critical to repair foundational problems as quickly as possible to avoid potential structural damage.

The water damage from foundations can result in a myriad of issues based on the way it is dealt with. If the damage is not addressed quickly, it can result in structural damage that is severe.


Roof Water Damage

Similar to foundation water damage roof water damage is also very common after natural disasters. Roof damage can lead to roof leaks, and can also cause damage to the foundation of a building or house.

Roof leaks are expensive and may have significant drawbacks. A leak in the roof could result in mold and mildew to develop, which could be deadly. A roof that is leaky could harm the roof truss system that can lead to structural damage to the roof.

Leaks from the ceiling could cause your rafters to decay and soften if you don’t deal with them right away. Electrical faults are also prevalent in the case of roof water damage that can lead to an electrical fire. All of these are excellent reasons to have roof water damage repaired quickly after a flood or any other sudden damage.

HVAC Water Damage

Your home may suffer structural damage if your HVAC system fails or faulty equipment is installed. If you do not have HVAC you’re opening the interior of your business or home to all sorts of issues. The growth of mold can cause a variety of very serious health problems.

Pipe water damage

If you’re suffering from pipe damage due to water, it is likely to be from a pipe that has burst in your home. When you’ve identified an issue, it’s essential to contact an expert to prevent the water from damaging the structure.

A burst pipe can cause devastating damage. When your pipes break they can let water into your home, causing severe damage , and may require water damage repair – an event that could bring with it structural damages.

Stop the water supply and call an expert IICRC-certified specialist with a firm for water restoration like Critical Control as soon as you spot damaged water pipes.

What’s the price to repair the water damage?

Water damage restoration cost per square foot

Repair and cleanup cost will differ based on the square footage you own. National Flood Services has the following breakdown of pricing for each square foot:

Are water damages insured by the homeowner’s insurance?

Insurance policies for homeowners are typically applicable if the source of the damage is sudden and accidental. According to the Insurance Information Institute, homeowners insurance policies can cover repair or replacement for a broken window, but not if the damage occurs as a result of neglect.

Damage from neglect may be defined as wear and tear to an object or surface due to exposure, lack of preventative maintenance, or general degradation. The Insurance Information Institute in the USA states that homeowners insurance will not cover damage caused by neglect.

A homeowners policy would not cover water damage due to flooding. Instead, a flood insurance policy is mandatory. Mortgage lenders might require flood insurance in specific areas. Flooding can be caused by storms, flooding ground or overflowing bodies of water or overflowing or surging bodies such as streams, lakes, rivers and oceans.
