Water Damage Restoration Guidelines Are In Place and you can call a Professional

Oftentimes, home or building owners try to tackle water damage using DIY solutions available on the internet. This is not advisable. There are guidelines for dealing with water damage and they depend on the tools and skills of professionals. These guidelines are detailed in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide exists because of the need for professional standards in cases involving water damage to homes and buildings as well as the risk they create.

Critical Control, a restoration business, can use IICRC guidelines to determine the extent and type of the project’s damages.

These guidelines are crucial for water damage professionals. In certain situations, the use of an Indoor Environmental Professional (IEP) is required. An IEP is someone who has the expertise and knowledge to assess an area for contamination, take samples, run lab tests, then provide us with advice regarding the type of water damage.

This is particularly important in situations where the occupants of the building could be high risk, there is a likelihood of adverse health consequences, or the occupants are required to determine the contaminants that are suspected, or some other reason for concern over contamination.

Water damages caused by categorizes and classes


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

The water that enters the building was classified based on its level of contamination. The first category is water that is clean like an unclean sink or tub, or a burst water supply.

Category 2 water has high levels of contaminants and can cause illness when it is ingested or contacted. This can include sources which might not appear to be dangers, such as the discharge from washing machines or toilet overflows.

Water in the category 3 is severely polluted, meaning it could have pathogenic, toxigenic or other harmful substances within it. This usually means contamination by toilet backflows following the toilet trap, seawater, water flooding from streams and rivers, or any other water arising from the exterior of the building. This water may include heavy metals, pesticides or other toxic substances.


It is also possible to use the IICRC’s courses to determine how much water has penetrated your property. The system basically serves as a guideline for the amount of water a building or residence should be.

The lowest degree of absorption by water and the most water is classified as Class 1. This happens when water is in contact with less than 5% building materials which absorb water. This is the situation that the majority of the building items affected by water are low in evaporation, which means that they aren’t able to absorb and hold water. Concrete, finished/coated wood, masonry or plaster.

Class 2 is a term used to describe water absorption and intrusion. This is about 5% up to 40% of combined ceiling, floor, and wall comprised of low-evaporation materials like plaster, concrete, wood or bricks and mortar.

Class 3 means that about 40 percent or more of wall, floor and ceiling materials are porous materials such as carpet, insulation, fiberboard etc. Other materials such as cement or plaster that don’t absorb water have not been adversely affected.

Class 4 refers to the fact that water is bound in materials that do not easily absorb water as wood, plaster, concrete and the masonry. This calls for special drying techniques and longer drying times.

How Drying a Water Damaged home or Building Works


Three ways of removing water from buildings include physical extraction, dehumidification, and evaporate. Removal of liquid water is at about 500 times more efficient than just making do with dehumidifiers and air mover. The quicker the structure dries the more efficient. The quantity of materials that needs to be extracted will affect both extraction and dehumidification techniques.

Water damage professionals employ a variety of extraction techniques. We have subsurface tools, wands, self-propelled tools, and vacuum squeezers.

Forced Evaporation

Once all water is removed, any remaining moisture is dried using high-velocity airmovers.

A submerged object absorbs moisture and water when it is moistened. The material becomes damp or wet as a result.

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

The evaporation stage is the time the time when water molecules transition from a liquid state to a gaseous form. The process is called evaporation.

In other words it is does not absorb any more moisture from the atmosphere. The saturation point is the point at which evaporation begins. When saturation is reached, drying will begin.

High-efficiency airmovers dry the object on two sides during the evaporation phase. They generate a large air flow over the entire surface, that is controlled through a filter system that covers the entire surface of the object.

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

Air movers dry objects about 10 times more quickly than the natural environment, in which there isn’t any air mover.

Airflows that are high-velocity removes the moisture from the surface and absorbs the water that is drawn out by airflow.

Utilizing Heat to Aid The Drying Process

Heat is an important component of any restoration project. To dry out materials which have been affected by water, we make use of various types of heaters.

Electric Heaters They are ideal to dry jobs that require several different heating sources. This is because they can be found in various power levels, which allows you to operate multiple heaters at once.

Electric heat can also be adjustable, allowing it to be turned down or off when the work is in process, without affecting your other heaters. To increase efficiency and reduce your energy bills, you can adjust the wattage of a heater while increasing it’s power.

Because they emit virtually no emissions and require very less water, electric heaters are very popular for restoration projects. They take longer to heat up and require longer drying time.

Hydronic Bioler (TES) Hydronic boilers are also very efficient at heating up quickly and generating minimal emissions. They can be powered by propane or natural gas.

Hydronic boilers differ from electric heat because they don’t use forced-air heat to spread heat. This makes it difficult to distribute heat evenly over large areas with these heaters. They also run at less temperature, which makes them ideal for drying jobs that require walls and ceilings to remain in place.

Hydronic boilers are often used when there is no electrical power to run electric heaters. They can generate radiant heat and keep your drying area warm without the need of an electrical source.


To dry houses and buildings that have been damaged by water damage, we make use of 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 in your home can remove water from the air in the same manner as an LGR Refrigerant Dehumidifier. It will also remove up to 99 percent of the airborne mold spores by eliminating condensation.

Repairing Wood Floor Water Damage

It is essential to take away the hardwood floors that have been damaged by water to allow repairs to be made from the subflooring up.

The subflooring has to be removed and repaired prior to. The hardwood floors affected need to be sanded or replaced. When the repairs are finished, the entire floor should be sanded and then refinished to ensure a uniform appearance.

Drywall that has been damaged by water

The extent of damage will determine the nature and method of drywall repair. Water damage repair can be simple as taking out a section of drywall, cleaning it, and after that, replacing it.

The opposite of this is that significant damage may need to be repaired completely, including the wall studs and fiberglass insulation.

Water damaged drywall often harbors mold spores that cannot be easily removed. Therefore, in the majority of cases the drywall needs to be replaced. We employ moisture testing instruments to assess the extent of the moisture. This allows us to identify damaged areas and keep costs restricted to only necessary damaged areas.

Water can also cause structural damage, since it causes the wood to expand or expand or contract. After the wood has been moistened by water, it becomes much more difficult to break. The wood may become brittle if it is left to dry in water for too long.


This problem can be avoided by homeowners and building owners taking immediate action to fix water-related structural issues that affect their property after flooding or other damages caused by water.

What’s the price to restore water damage?

Water damage restoration cost per square foot

Based on the square foot, water damage repairs and cleanup expenses differ. National Flood Services has the following pricing breakdown for each square foot:

Will Water Damage Be Covered By the Homeowner’s Insurance?

If the cause of the damage was sudden and unintentional, homeowners insurance policies will usually cover it. According to the Insurance Information Institute, homeowners insurance can cover repairs or replacement of a broken window, but not if the damage is a result of neglect.

Neglect is defined as damage to an object or surface that is caused by exposure, poor maintenance or general degradation. According to the Insurance Information Institute, a US-based Insurance Information Institute, homeowners insurance doesn’t cover damage from neglect.

If the damage to your property results from an event that is a flood, it is not covered under homeowner’s insurance. A flood policy is required. Mortgage lenders might need flood insurance in some areas. Flooding can be caused by storms, flooding the ground, overflowing bodies of water or overflowing or surging bodies like streams, rivers, lakes and oceans.
