Water Damage Restoration Guidelines are readily available – Call a Professional

Oftentimes, home or building owners attempt to address water damage using DIY solutions found on the internet. This isn’t a good idea. The management of water damage is according to established guidelines. These guidelines demand the knowledge and skills of professionals. These guidelines can be available 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 instances involving water damage to buildings or homes, and the risks associated with it.

The IICRC guidelines assist restoration experts like Critical Control to evaluate the category and class of damages on every project.

These guidelines are essential for professionals who deal with water damage. In certain situations it is necessary to employ an Indoor Environmental Professional (IEP) is essential. An IEP is a professional who has the experience and knowledge to examine the condition of a place, collect samples, get laboratory tests, and advise us on the category of water damage.

This is crucial when the building’s inhabitants are at risk or have concerns regarding contamination.

Categories and classes of Water Damage


Projects for water damage restoration are divided into two categories, depending on how extensive the infiltration of water is.

The classification is based on how polluted the water that entered the structure was. Category 1 is water that is clean such as the sink or tub, or a burst water supply.

Category 2 involves water that has high levels of contaminants and has the potential to cause discomfort or illness if contacted or consumed. The sources could be water that isn’t obvious as a risk, such as the discharge from washing machines and overflows from toilets.

Category 3 water can be considered to be extremely contaminated. It could be contaminated by pathogenic, toxic, or other harmful substances. This can be caused by backflows of sewage, toilet trap leaks, and floods of water from rivers and streams. The water in this category could include heavy metals, pesticides, regulated materials or toxic substances within it.


The IICRC has also developed classes we use in measuring the amount of water intrusion on your property. This system basically sets guidelines for the level of saturation of the home or building.

The lowest level of water absorption , and the most water is classified as Class 1. It is the case when water is in contact with about 5% or less with construction materials 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 retain water. Examples include concrete, coated or finished wood, plaster , or masonry.

Class 2 means that there is substantial absorption of water and intrusion. It’s about 5 up to 40% of the total ceiling, floor, and wall are composed of low evaporation materials like plaster, concrete, wood, or the masonry.

Class 3 is the term used to describe 40 percent or more of flooring, walls and ceiling surfaces are porous like fiberboard, insulation, carpet and so on. and where other materials that don’t take in a lot of water, such as plaster or concrete have not been adversely affected.

Class 4 refers to the fact that water is trapped in the materials that can not easily absorb water as wood, plaster, concrete and bricks and mortar. This calls for special drying techniques and longer drying time.

How to Dry a Water Damaged Building or Home Building Works


Three methods for removing water from buildings are physical extraction, dehumidification and the process of evaporation. Eliminating liquid water is at most 500 times more efficient than using dehumidifiers or air movers. The faster the structure can dry, the more efficient. Both methods of extraction and dehumidification will be affected by the amount of much material is being removed.

Water damage experts employ an array of extraction techniques. We use a variety of tools including self-propelled and subsurface extraction tools.

Forced Evaporation

After the water is removed, any moisture remaining is dried with high-speed airmovers.

Submerged objects absorb water and moisture once it’s moistened. The material gets wet or damp as a result.

The saturation level is referred to as the point at which it is impossible to hold any more moisture. The higher the humidity, the more close the air is to being saturated.

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

This signifies that the object no longer absorbs moisture from the atmosphere. This is known as the saturation point. As soon as saturation is attained the drying process starts.

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

Air mover is able to move around 10 to 20 percent more air than a fan, or an ordinary fan in your home.

Airmovers dry the object approximately 10 times more quickly than normal conditions, when there is no air movement.

Airflows with high velocity dry the surface and absorbs the water that is drawn out by airflow.

Utilize heat to aid in the drying process.

A key component of any restoration work is heating. We use a variety of heaters to dry the materials that have been damaged by water.

Electric Heaters: These heaters can be used for drying jobs that require multiple heat sources. It is possible to run several heaters simultaneously because of their numerous power ratings.

You can also turn down or off electric heat while the job is being done, and not affect other heaters. This means that you could lower one heater, while increasing the wattage of another to maximize efficiency and reduce your expenses for energy.

Electric heaters are a common feature in restoration work since they generate virtually no emissions and require minimal amounts of water. The only issue is that they take longer time to warm up, which means that they require more time to dry process in general.

Hydronic Bioler (TES) Hydronic Bioler (TES) These boilers heat up quickly and emit very little emissions. They are typically run with propane or natural gas.

Hydronic boilers differ from electric heat since they don’t utilize forced air heat to disperse heat. This makes it difficult to evenly heat large areas by using these heaters. They can also be used to dry out jobs that do not require walls or ceilings to be able to stand in the same place.

In the event that electric heaters can’t be employed, hydronic boilers may often be used. They can generate radiant heat and can keep your drying space warm without the need of electricity.


We utilize low Grain Refrigerant Dehumidifiers (LGR) to keep buildings dry and homes that have experienced water damage.

The LGR Home Dehumidifier can extract 170 pints 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 way as an LGR Refrigerant Dehumidifier. It can remove the 99 percent or more of the airborne mold spores by eliminating condensation.

Repairing Hardwood Floor Water Damage

It is essential to take away flooring that has been damaged by water to ensure that repairs can be completed by removing the subflooring.

The subflooring has to be removed and repaired prior to. Next, the hardwood boards damaged need to be replaced or sanded. In order to ensure a uniform appearance, all floors should be sanded and restored after the repairs are completed.

Carpets are vulnerable to water damage

If you have had the misfortune of experiencing flooding in your house it could be a costly and stressful experience. It is possible that you will need to replace your flooring, even if you have eliminated the water from the area as fast as possible.

It’s devastating to discover that your house isn’t in the best condition after spending many hours and dollars to restore it.

Because of this, it is crucial to determine the extent of the damage as quickly as is possible. One of the first things that must be resolved is whether or not the damaged region should be replaced. It is possible to wash the carpet and then use it after drying. This can eliminate concerns about mildew growth or persistent odors.

Salvaging Carpet After a Water Damage Event

Drywall that has been damaged by water

The procedure for repair of drywall differs according to the extent of damage. Repairing water damage is as easy as removing the drywall section, cleaning it, and then replacing it.

On the other side of the coin serious damage could require a complete reconstruction of the wall, which could include walls studs and fiberglass insulation.

There are spores of mold in damaged drywall, which is difficult to remove. In the majority of cases, the drywall will have to be replaced. We utilize moisture testing tools to measure the amount of the moisture. This allows us to identify damaged areas and limit the cost to the only damaged ones.

Water can also cause structural damage, since it causes the wood to expand or contract. After the wood has been moistened with water, it’s much more difficult to break. The wood can be brittle if left to dry in water for too long.


This problem can be avoided by building owners and homeowners taking immediate action to fix structural damage from moisture-related problems with their property following flooding or other damages caused by water.

Water Damage to the Foundation

There are many reasons water damage could affect a foundation of a house. Although not all water issues result in structural damage, it’s crucial to address foundational issues in the quickest time possible to avoid structural damage.

Water damage to the foundation can trigger a number of different issues dependent on the way it is dealt with. It can lead to serious structural damage if the issue isn’t taken care of promptly.


Roof Water Damage

Like foundation water damage, roof water damage is quite common following natural catastrophes. Along with creating roof leaks damage can cause problems with the walls and foundations of a the building.

Roof leaks are expensive and have serious disadvantages. Leaks in the roof could result in mold and mildew to develop, which could cause death. The leaks in the roof could also cause damage to the roof truss system.

If you don’t fix leaks in your ceiling right away the risk is that the rafters to decay and then soften. Water damage to the roof could result from electrical faults, which can lead to an electrical fire. These are all good reasons to have your roof water damage repaired quickly after a flood or other type of unexpected damage.

HVAC Water Damage

Your home may be damaged structurally if your HVAC system is not working properly or the wrong equipment is put in place. If you do not have HVAC you’re exposing the inside of your home or business to all kinds of problems. The growth of mold can cause severe health issues.

Damage to the Pipe Water

If you’re suffering from pipe water damage, it is likely to be from a pipe that has burst in your home. Once you’ve determined there’s an issue, it’s essential to contact a professional to stop the water from creating structural damage.

A burst pipe can cause severe damage. When pipes are damaged they can let water into your home, causing extensive damages and necessitating water damage repair – a process that can result in structural damage.

Stop the water supply, and then contact an expert IICRC-certified specialist with a firm for water restoration such as Critical Control as soon as you spot broken pipes or water damage.

What is the cost to repair the damage caused by water?

Water damage restoration cost per square foot

Based on the square foot, water damage repair and cleanup costs vary. The following breakdown of pricing can be obtained at National Flood Services for each square foot

Are water damages covered by homeowners’ insurance?

The homeowner’s insurance policies are generally appropriate if the damage is unexpected and unintentional. The Insurance Information Institute states that homeowners insurance may be used to pay for repairs or replacement of windows that have been damaged but not for damages caused by negligence.

Damage from neglect could be described as wear and tear on a surface or object because of exposure, lack of preventative maintenance, or general degradation. According to the US-based Insurance Information Institute, homeowners insurance will not cover damages due to neglect.

If the damage to your property is the result of flooding, the incident would not be covered by homeowner’s insurance. A flood policy is mandatory. Mortgage lenders may require flood insurance in specific areas. Flooding can happen because of storms, ground that is saturated to the point of flooding or overflowing bodies of water, such as rivers, ponds, lakes rivers, oceans, and streams when combined with strong winds.
