Water Damage Restoration Guidelines are Available for your reference. Call a Professional

Oftentimes, home or building owners attempt to deal with water damage using DIY solutions available on the internet. This is not a good idea. Water damage can be managed according to the established guidelines. These guidelines demand the expertise and equipment of experts. 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 for professional standards in cases involving water damage to homes and buildings and the dangers they can present.

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

These guidelines are crucial for professionals dealing with water damage. There are certain situations that require our bringing in the services of an Indoor Environmental Professional (IEP). An IEP is a person who has the expertise and experience to analyze a site for contamination collect samples, perform lab tests, and then give us advice on the nature of the water damage.

This is especially important when the building’s residents are at high risk or are concerned regarding contamination.

Categories and Classes of Water Damage


Restoration projects for water damage are classified by category and class depending mostly on the severity of the flooding of water.

The category has to do with how polluted the water entering the structure is. Category 1 water comes from a clean source like an unclean sink or tub, or a water source that bursts.

The category 2 water has significant levels of contaminants, and could be able to cause discomfort or illness if contacted or consumed. These sources can be water that is not obvious as a risk such as the effluent from washing machines or overflows from toilets.

Water in Category 3 can be considered extremely contaminated. It could be contaminated by pathogenic, toxic, or other harmful substances. This could be due to backflows of sewage, toilet trap leaks, and water flooding from rivers and streams. This water may be contaminated by pesticides, heavy metals or harmful substances.


The IICRC has also developed classes that we follow in determining the degree of water intrusion into your property. This is basically an outline of how saturated a building or home ought to be.

Class 1 means the least amount of absorption and the amount of water. This happens when water comes into contact with less than 5% of the building materials which absorb water. This is usually the case in which the majority of substances affected by water have low evaporation. This means they aren’t able to absorb and retain water. Concrete and masonry, as well as plaster and wood that has been finished/coated are several examples.

Class 2 means that there is substantial infiltration of water as well as intrusion. It is approximately 5 up to 40% of the combined ceiling, floor, and wall comprised of low-evaporation materials like plaster, wood, concrete, or bricks and mortar.

The porous materials like carpet, insulation and fiberboard, that make up Class 3 comprise around 40% of floor, wall and ceiling materials. This includes approximately 40% of the materials in Class 3. and also where other materials that do not absorb water like concrete or cement have not been adversely affected.

Class 4 means that water has been deeply bound in materials that do not readily absorb water, such as concrete, wood, and bricks and mortar. This will require more time to dry and special drying techniques.

How to Dry a Water Damaged House or Building


Three ways to remove water from buildings include physical extraction, dehumidification, and evaporate. The removal of liquid water is at least 500 times more effective than simply making do with dehumidifiers and air mover. The quicker the structure can dry more efficiently. The extraction method and the dehumidification process are affected by how much of the material is extracted.

Water damage experts employ different extraction techniques. Some of our tools include subsurface tools, wands as well as self-propelled tools and vacuum squeezers.

Forcible Evaporation

After the water has been removed, any moisture remaining is dried using high-velocity airmovers.

When an object gets wet or submerged in water it absorbs some of the water or moisture. The object becomes damp or wet as a result.

Saturation is the time at which it becomes impossible for the air to contain any moisture. Higher humidity means that the air is closer to saturation.

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

In this way it is does not absorb any more moisture from the atmosphere. This is known as the saturation point. the point at which evaporation begins. When saturation is reached, drying starts.

In the evaporation phase high-efficiency air mover dry the object from two sides. They produce a powerful airflow over the surface of the object that is controlled by a filter system that completely covers the area of the object.

An air mover moves around 10 to 20 times more air than a fan or an ordinary household fan.

The item is dried using airmovers about 10 times faster that in the natural environment where there was no air movement.

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

Utilizing Heat to Aid The Drying Process

Heating is a crucial element of any water damage restoration job. We use a variety of heaters to dry out materials that have been damaged by water.

Electric Heaters They are ideal for drying tasks that require several different heat sources. This is because they can be found in various power levels, which allows you to use multiple heaters at the same time.

Electric heat is also capable of being shut off or reduced during the process, without affecting your other heaters. This means that you can lower one heater, while raising the wattage of another one to improve efficiency and reduce your cost of energy.

Electric heaters are very common in restoration projects since they generate virtually zero emissions and consume very little water. They are more difficult to warm up and need longer drying time.

Hydronic Bioler (TES) Hydronic Bioler (TES), These boilers heat up quickly and release very little CO2. They are typically run using propane or natural gas.

Hydronic boilers are different from electric heating in the sense that they don’t make use of forced air to distribute heat, so it can be challenging to evenly heat an area using these kinds of heaters. They can also be utilized for dry work that does not require ceilings or walls to be able to stand in the same place.

In the event that electric heaters can’t be utilized, hydronic boilers can often be used. Because they are extremely efficient in producing radiant heat, they are able to keep your drying space warm even without an electrical power source.


To dry buildings and houses that have been damaged by water damage, we employ low Grain Refrigerant (LGR) Dehumidifiers.

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

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

Fixing Hardwood Floor Water Damage

Hardwood floors damaged by water have to be ripped up so repairs can be made from the subflooring upwards.

First, damaged subflooring needs to be removed and repaired. The hardwood floors damaged need to be sanded or replaced. To ensure a uniform appearance, all floors should be sanded, then repaired after these repairs are completed.

Carpets Damaged by Water

Floods can cause significant destruction to your home and make it costly and difficult to repair. You may need to replace your flooring, even if you have removed the water from the area as quickly as you can.

It is vital to identify the extent of damage as soon as possible. First thing to do is determine if the affected part requires replacement. There is a way to wash the carpet, then use it after drying. This can eliminate worries about the growth of mildew or persistent odors.

Salvaging Carpet After a Water Damage Event

If the water damage has been very severe there is a chance that you will have noticeable marks on your carpet. In some cases the only option to get rid of the stains is to replace the flooring. An odor that is persistent and strong could also be a reason to change your carpet. It’s time to change your carpet and padding when this happens.

The next step in determining whether or not you’ll need to replace your carpet is to assess whether the flooring is able to be dried and cleaned professionally. A professional service will be able to aid you in determining the severity of the damages were. We can assess whether your carpet needs to be replaced or salvaged. If the carpet you have is damaged, a few drying methods could further harm it.

Some of the considerations which will decide whether or not the carpet and padding should be replaced include:

Do your carpets get professionally cleaned, dried and disinfected?

If the padding underneath your carpet has been damaged, it could affect the time that your carpet can last. Although your carpet might be dry, the possibility of mildew development is present if the padding under it is not dried out as well.

A professional carpet cleaning service is the best option to ensure your carpet is clean and dry after the flood. After the company completes their work, you will be able to make a more informed decision regarding the condition of your carpet and decide whether or not you need to change it.

Drywall that has been damaged by water

The degree of damage determines the type and method of drywall repair. Repairing water damage can be as simple as removing an area of drywall, cleaning it, and after that, replacing it.

On the other side of the coin, serious damage might necessitate whole wall replacement, including wall studs and fiberglass insulation.

The spores of mold can be seen in drywall damaged by water that is difficult to remove. In most instances drywalls will have to be replaced. We utilize moisture testing tools to assess the extent of the moisture. This helps us identify areas that are damaged and limit costs to the only damaged ones.

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


To avoid this problem, it’s crucial for building owners and homeowners to address structural damages from water-related issues with their properties immediately following a flood or water damage incident.

Water Damage to the Foundation

There are a variety of reasons that water damage can affect the foundation of a home. While not all issues with water cause structural damage, it’s crucial to address foundational issues as quickly as possible to prevent structural damage.

Water damage to the foundation can lead to many different problems based on how it’s treated. It can cause severe structural damage if it isn’t addressed promptly.


Roof Water Damage

Damage to the roof can be caused by natural disasters as well as foundation water damage. Roof damage can lead to roof leaks and also damage the foundation of a structure or the foundation of a home.

Roof leaks can be costly and have serious disadvantages. The roof’s leaks could cause mold to grow, which can prove fatal. A leaky roof can affect the roof truss structure and cause structural damage to the roof.

If you don’t take care to address the leaks in your ceiling promptly the risk is that the rafters to decay and then soften. Electrical problems are also common in the case of roof water damage that can lead to the possibility of an electrical fire. These are all good reasons to get roof water damage repaired quickly after a flood or any other unexpected damage.

HVAC Water Damage

Your home can be damaged by structural damage if the HVAC system fails or is defective equipment is put in place. If you do not have HVAC it is exposing the inside of your home or business to all sorts of issues. It can lead to severe health issues.

Pipe water damage

Water damage to pipes is typically caused due to a pipe burst within your home. If you’ve determined there has been an issue, it is important to get professional help to stop the leak and ensure it doesn’t lead to structural damage.

A burst pipe can cause devastating damage. If your pipes fail they can let water into your home, causing severe damage and requiring repairs for water damage – a process that can cause structural damage.

When you see broken pipe water damage stop the supply of water.

What is the cost of the restoration of water damages?

Water damage restoration cost per square foot

Based on the square feet the repair and cleanup costs vary. The following pricing breakdown can be obtained from National Flood Services for each square foot

Is water damage covered by homeowners’ insurance?

If the cause was unintentional and sudden the homeowners insurance policy typically cover the damage. According to the Insurance Information Institute, homeowners insurance may cover repair or replacement for a damaged window, but not when the damage is a result of neglect.

Neglect is defined as damage to a surface or an object that results from exposure, poor maintenance or general wear and tear. The Insurance Information Institute in the US declares that homeowners insurance does not cover the damage caused by negligence.

If the damage to your property resulted from flooding, the incident is not covered under the homeowners insurance. Rather, a flood policy would be required. In some areas the flood policies are demanded by mortgage companies. Flooding can happen due to storms, ground that is saturated to the point of overflowing or surging bodies of water, such as rivers, ponds, lakes, streams, oceans together with high winds.
