Water Damage Restoration Guidelines are readily available – Call an Professional

A lot of times, property or home owners try to tackle water damage using DIY solutions available online. This is inadvisable. There are guidelines to deal with water damage , and they depend on the equipment and expertise of professionals. These guidelines are detailed in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide is required to ensure that there is a professional standardisation for instances involving water damage to houses or buildings, and the risk associated with it.

The IICRC guidelines aid restoration professionals like Critical Control to evaluate the kind and severity of the damage to each project.

These guidelines are essential for water damage professionals. There are situations that warrant our bringing in the services of an Indoor Environmental Professional (IEP). An IEP is professional with the training to assess a site for contamination and collect samples, conduct lab tests, and then provide us with the type of water damage.

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

Categories and Classes of Water Damage


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

The water that entered the structure was classified according to the degree of contamination. Category 1 water is clean like a tub or sink or burst water supply.

The category 2 water has high levels of contaminants and is likely to cause discomfort or illness if contacted or consumed. These sources can be water that isn’t obvious as a risk such as the effluent from washing machines or overflows from toilets.

Water in the category 3 is severely contaminated meaning that it can contain toxic, pathogenic or any other harmful agent in it. It can be caused by sewage backflows, leaks in toilet traps, and floods of water from rivers and streams. This category of water can include heavy metals, pesticides, regulated materials or toxic substances within it.


You can also utilize the IICRC’s courses to determine how much water has penetrated your property. This is basically an indication of the amount of water a building or residence ought to be.

The lowest degree of water absorption 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 substances that absorb water. This is typically the case in which the majority of items affected by water are low evaporation. This means they don’t soak up and hold water. Concrete, plaster, masonry, and finished/coated wood are just some of the examples.

Class 2 signifies that there is a significant absorption of water and intrusion. This means that between 5 to 40% of the floor, ceiling and wall is made of low-evaporation materials like plaster, concrete, wood or masonry.

Class 3 refers to the fact that around 40 percent or more of floor, wall, and ceiling surfaces are porous materials like fiberboard, insulation, carpet and so on. and also where other materials that don’t absorb water like concrete or cement have not been adversely affected.

Water has been absorbed into materials like concrete or plaster and wood that are classified as Class 4. This calls for special drying techniques and longer drying times.

How to Dry a Water Damaged House or Building


Three methods for removing water from buildings are physical extraction, dehumidification, and evaporate. Removal of liquid water is at least 500 times more effective than simply making do with dehumidifiers and air moving machines. The faster the structure is dried, the better. Both extraction and dehumidification methods will be affected by the amount of much material is being removed.

Water damage experts employ an array of extraction techniques. Our tools include wands, subsurface extraction tools Self-propelled tools, self-propelled instruments, and vacuum squeegees.

Forced Evaporation

The remaining moisture is dried using high-speed air movers once as much water as has been removed.

A submerged object absorbs moisture and water when it’s moistened. The material gets wet or damp as a result.

Saturation is defined as the point at which it becomes impractical for the air to contain any moisture. The higher the humidity, the more close the air is getting to saturation.

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

This signifies that the object has stopped absorbing water from the air. We call that saturation point the point of evaporation. Once saturation is attained the drying process starts.

High-efficiency air movers dry objects on both sides during the evaporation phase. They create a strong air flow over the surface of the object, which is directed through a filter system that is able to cover the entire surface of the object.

Air mover can move 10 to 20 times the amount of air than a fan or the typical household fan.

The object is dried using airmovers about 10 times faster that in natural conditions in which no air mover was used.

Airflows that are high-velocity leaves the surface dry and absorbs the water pulled out by the air movement.

Utilizing Heat to Aid The Drying Process

The most important element for any water damage restoration project is heating. We make use of a variety heaters to dry the materials that have been damaged by water.

Electric Heaters: These heaters can be used for drying jobs which require multiple sources of heat. You can run multiple heaters simultaneously due to their numerous wattages.

Electric heat can also be capable of being reduced or turned off when the work is in process, but without impacting other heaters. In order to maximize efficiency and lower your expenses for energy you can alter the wattage of a heater, while also increasing its capacity.

Electric heaters are common in restoration projects since they generate virtually zero emissions and consume minimal amounts of water. They take longer to warm up and need more time to dry.

Hydronic Bioler (TES) Hydronic Bioler (TES) These boilers heat up quickly and release very little CO2. They typically operate on natural gas or propane.

Hydronic boilers are different from electric heat in that they don’t make use of forced air to distribute heat, which means it could be challenging to evenly heat an area with these types of heaters. They also run at less temperature, which makes them perfect for drying tasks that require ceilings and walls to remain in place.

If electric heaters are not used, hydronic boilers can frequently be employed. They can generate radiant heat, and they can keep your drying space warm without the requirement of electricity.


We employ low Grain Refrigerant Dehumidifiers (LGR) to keep buildings dry as well as houses that have suffered water damage.

The LGR Home Dehumidifier can extract 170 pints water from damp structures that have experienced severe water damage within 24 hours.

The dehumidifier at home is able to remove water from the air the same way it does an LGR Refrigerant Dehumidifier. It can eliminate the 99 percent or more of airborne mold spores by removing condensation.

Repairing Wood Floor Water Damage

The floors that have been damaged by water need to be ripped up so repairs can occur from the subflooring upwards.

First, damaged subflooring needs to be removed and replaced. Next, the hardwood boards affected need to be sanded or replaced. When the repairs are finished and the floor is finished, it should be sanded and then refinished to ensure a uniform appearance.

Carpets are prone to water damage

Floods can cause significant damage to your home and cause it to be costly and difficult to repair. You might need to change your flooring even if you’ve eliminated the water from the area as fast as possible.

After investing time and money in restoring your home to its pre-flooding condition, it will be depressing to discover that the finished results leave something to be desired.

In this regard, it is crucial to determine the extent of damage as quickly as is possible. First thing to do is to determine if the damaged area needs to be replaced. There is a good chance that the carpet will be cleaned and used once it is dry, and this cleaning can help to eliminate the concerns about mildew growth and the lingering smells.

Salvaging Carpet After a Water Damage Event

There may be stains on your carpeting , especially if the damage from water was serious. In some instances the only solution to get rid of these stains is to replace the flooring. Another reason that might prompt you to think about replacing your carpet is a strong and lingering scent. It’s time to replace your padding and carpet in the event of this.

Then, consider if your floor can be professionally dried before you decide whether to change it. If you’ve got an established company that can handle the cleaning, then you will have a better understanding of how serious the damage was. We can determine if the carpet should be replaced or salvaged. If the carpet you have is in poor shape, some drying methods can cause further damage to it.

Some of the considerations which will decide whether or whether the padding and carpet need to be replaced are:

Are your carpets dry, cleaned and disinfected professionally?

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

The safest way to ensure that your carpet is cleaned and disinfected following an event of flooding is to engage a professional carpet cleaning company. Once the work is done you’ll be able to make an informed decision on the condition of your carpeting. You’ll also be able to determine whether you want to replace it.

Drywall that has been damaged by water

The degree of damage determines the nature and method of drywall repair. Repairing water damage may be as easy as removing the drywall portion, cleaning the area, and replacing it.

The other side is that significant damage may 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. Most of the time the drywall will need to be replaced. We use moisture testing equipment which allow us to identify the extent to which water has grown. This allows us to identify the areas that are damaged and keep costs restricted to areas that need to be repaired.

Water can also cause structural damage, since it causes the wood to expand or shrink. When the wood is saturated by water, it becomes a lot easier to break. If the water is left to sit for a long period of time, there could be an abundance of rot within the wood, which could make it break easily.


This problem can be avoided by owners of buildings and homeowners immediately taking action to repair structural damage from moisture-related problems with their property following a flood or other damages caused by water.

Water Damage to the Foundation

There are a variety of reasons that water damage can affect a foundation of a house. While not all water concerns result in structural damage, it is critical to repair foundational problems promptly to avoid potential structural damage.

Water damage to the foundation can trigger a number of different issues in the manner it is handled. If the problem isn’t treated quickly, it can cause serious structural damage.


Roof Water Damage

Similar to foundation water damage roof water damage is quite common following natural catastrophes. Roof damage could cause roof leaks as well as damage the foundation of a structure or home.

Roof leaks can be very costly and can have significant negatives. The roof’s leaks could result in the growth of mold that could be fatal. Leakage in the roof can also cause damages to the roof truss.

Leaks in the ceiling can cause your rafters to decay and soften if you don’t deal with them right away. Electrical problems are also common when it comes to roof water damage that can lead to the possibility of an electrical fire. All of these are excellent reasons to have your roof water damage repaired swiftly following a flood , or any other damage that is unexpected.

HVAC Water Damage

If your HVAC system starts to fail or brand-new equipment is found to be defective, it could cause the structure of your home. You are putting your business and your home at risk in the absence of HVAC. It is possible for mold to grow and result in a range of serious health issues.

Pipe Water Damage

Water damage to pipes is typically caused by a burst pipe within your home. If you’ve discovered leak, it’s important to call a professional to stop the water from damaging the structure.

A burst pipe can cause devastating damage. Water can enter your home via broken pipes, causing extensive damage. It could cause structural damage.

As soon as you notice broken pipe water damage stop the water supply.

What’s the cost for cleaning up water damage?

Water damage restoration cost per square foot

Depending on the square foot, water damage repairs and cleanup expenses vary. National Flood Services has the following breakdown of pricing per square foot.

Can Water Damage be covered By Homeowner’s Insurance?

If the cause was sudden and unintentional, homeowners insurance policies generally cover it. The Insurance Information Institute states that homeowners insurance may be used to pay for repairs or replacement of broken windows however, it does not cover damage caused by negligence.

Neglect is defined as damage to an object or surface that results from exposure, poor maintenance or general deterioration. The Insurance Information Institute in the USA states that homeowners insurance will not cover the damage caused by negligence.

If the water damage results from a flood, the event is not covered under homeowner’s insurance. Rather, a flood policy would be necessary. Mortgage lenders may require flood policies in certain areas. Flooding can be caused by storms, flooding ground or overflowing bodies of water or overflowing or surging bodies like streams, rivers, lakes and oceans.
