If a storm, flood, or burst pipe causes water to seep into a home or structure, water damage occurs most of the time. Sometimes the damage is overt and evident, while other times it’s subtle or even hidden.

Remediation of water damage is more complicated than just drying the interior. Modern professional methods for water damage remediation like Critical Control, can often minimize damage that otherwise would require a complete structural replacement.

Water Damage Restoration Guidelines are in place so call a Professional

Many times, homeowners or builders try to fix water damage with DIY solutions that can be located online. This is a mistake. There are guidelines for dealing with water damage and they depend on the skills and tools of experts. These guidelines are detailed in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide exists because of the necessity for professional standardisation of situations that involve water damage to buildings and homes as well as the risk they create.

Critical Control, a restoration firm, is able to use IICRC guidelines to assess the type and extent of the damage each project has sustained.

There are really important reasons why professionals dealing with water damage must follow these guidelines. In certain circumstances there are situations where an Indoor Environmental Professional (IEP) is essential. An IEP is someone who has the skills and training to evaluate an area for contamination collect samples, perform lab tests and give us advice on the type of water damage.

This is crucial in situations where the building’s occupants are at high risk or there is concern about contamination.

Categories and Classes of Water Damage


Projects for water damage restoration are divided into two categories according to the extent of the infiltration of water is.

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

The category 2 water contains significant amounts of contaminants and has the potential to cause discomfort of illness if contacted or consumed. This could include waters that are not readily apparent as a risk, such as the discharge from washing machines, or the overflows from toilets.

The water in the category 3 is considered to be extremely contaminated. It could contain pathogenic, toxic, or any other harmful substances. This could be due to toilet trap leaks, and floods of water from streams and rivers. This water can contain pesticides, heavy metallics or toxic substances.


It is also possible to use the IICRC’s courses to determine how much water has gotten into your property. The system basically serves as a guideline for how saturated a building or home is.

Class 1 is the smallest amount of absorption and water. This is the case when water comes in contact with less than 5% of the building materials that absorb water. This is typically the case in which the majority of substances affected by water have low evaporation, meaning, they aren’t able to absorb and retain water. Concrete, plaster, masonry, and finished/coated wood are just several examples.

Class 2 means that there is significant infiltration of water as well as intrusion. This is about 10% up to 40% of the total floor, wall and ceiling consist of low evaporation materials such as plaster, concrete, wood, or the masonry.

Class 3 is the term used to describe 40% or more of the flooring, walls and ceiling materials are porous like fiberboard, insulation, carpet and so on. Other materials such as concrete and plaster that do not absorb water haven’t been adversely affected.

Class 4 refers to the fact that water has become deeply bound in materials that do not easily absorb water like concrete, wood, and bricks and mortar. This means that it requires longer drying times and special drying techniques.

How to Dry a Water damaged building or house


Three ways of removing water from buildings are physical extraction, dehumidification and the process of evaporation. Eliminating liquid water is at most 500 times more efficient than dehumidifiers and air movers. The faster the structure dries, the better. The extraction method and the dehumidification process will be affected by how much material is being removed.

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

Forced Evaporation

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

If an object is wet or submerged in water it absorbs a portion of the moisture or water. The substance becomes damp or wet as a result.

Saturation is defined as the point where it becomes unachievable for air to hold any moisture. The greater the humidity, the closer the air is to being saturated.

In the evaporation stage in which water molecules are ejected from a liquid to a gaseous state. The process is referred to as evaporation.

In other words the object does not absorb any more moisture from the air. This is called the saturation point. When saturation is reached the drying process commences.

High-efficiency air movers dry the object on both sides during the evaporation phase. They produce strong airflow that is controlled by a filter system.

A fan that moves air can move 10-20 times more air than a fan , or the typical household fan.

The object is dried using air movers approximately 10 times faster that in natural conditions in which no air mover was employed.

A high-velocity airflow dries the surface and draws in the moisture pulled out by the air movers.

Utilizing Heat to Aid the Drying Process

Heat is an important component of any restoration job. We employ a variety of heaters to dry the materials that have been damaged by water.

Electric Heaters: Electric heaters are great for drying tasks that require the use of various heating sources. This is due to the fact that they can be found in various wattages, allowing you to run multiple heaters simultaneously.

You can also turn down the electric heating as the work is done, and not affect other heaters. This means that you can reduce one heater while increasing the wattage of the other to increase efficiency and reduce your expenses for energy.

Since they produce virtually zero emissions and consume very minimal water, electric heaters are very used in restoration projects. The only issue is they take longer to heat up, requiring more time to dry process overall.

Hydronic Bioler (TES): These boilers are extremely efficient in heating up quickly, while still producing low emissions. They are typically run on natural gas or propane.

Hydronic boilers differ from electric heat in that they do not utilize forced-air for distribution of heat, which means it could be challenging to evenly heat a large space with these kinds of heaters. They can also be used for dry work that does not require walls or ceilings to be able to stand in place.

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


We use low Grain Refrigerant Dehumidifiers (LGR) to keep buildings dry and houses that have suffered water damage.

The LGR Home Dehumidifier can remove 170 pints of moisture from damp structures that have suffered extensive 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 get rid of up to 99 percent of the mold spores that are airborne by eliminating condensation.

Repairing Hardwood Floor Water Damage

The floors that have been damaged by water need to be cut up to ensure repairs can be made beginning with the subflooring and moving upwards.

First, damaged subflooring needs to be taken off and fixed. Next, the hardwood boards damaged need to be replaced or sanded. In order to ensure a uniform appearance, all floors should be sanded and refinished after these repairs are completed.

Water Damage to Carpeting

Floods can cause severe damage to your home and can make repairs expensive and time-consuming. Even if water is removed from the affected area immediately, there is still a chance that you’ll need to replace the flooring in the future.

It’s a huge shock to discover that your house isn’t in the best condition after spending many hours and dollars to repair it.

It is crucial to determine the severity of the damage as quickly as possible. One of the first issues to address is whether the damaged area should be replaced. It is possible to wash the carpet and use it after drying. This will eliminate any concerns about mildew growth or lingering odors.

Salvaging Carpet After a Water Damage Event

There could be staining on your carpeting , especially if the water damage was very serious. In certain instances the only solution to remove the stains is to replace the flooring. A strong, lingering odor can also be an indication to replace your carpeting. You will need to replace your carpet padding and padding when this happens.

Then, consider if your floor can be dried professionally before deciding whether you want to repair it or replace it. If you can have a reliable company do the cleaning, then you’ll have a better understanding of how severe the water damage was. Our team will evaluate the carpet and decide whether it’s worth replacing or salvageable. If the carpet you have is damaged, a few drying methods could further harm it.

A few of the factors that will determine whether or whether the padding and carpet should be replaced include:

  • How much water dripped onto your carpet?
  • What was the duration of water on the carpet?
  • Quel was the source of the water?

Are your carpets professionally cleaned, dried and cleaned?

If the padding underneath your carpet is also damaged, it could affect how long the carpet is clean. Although your carpet may have dried quickly, mildew growth is still possible when the padding beneath isn’t dried.

The best way to be sure that your carpeting is properly cleaned and disinfected following an event of flooding is to engage an expert carpet cleaning service. Once the work is done then you’ll have the ability to make an informed decision about the state of your carpet. You’ll also be able to determine whether to replace it.

Drywall Damaged by Water

The procedure for repair of drywall differs according to the extent of damage. Repairing water damage could be as simple as removing some drywall and cleaning the area and then replacing it.

On the other side of the coin severe damage might necessitate whole reconstruction of the wall, which could include walls studs and fiberglass insulation.

The spores of mold can be seen in drywall damaged by water that is difficult to remove. In most instances, drywall will need to be replaced. We use moisture testing equipment that help us determine where and how extensive the humidity has gotten. This allows us to identify damaged areas and limit costs to those areas that are only damaged.

The water can also cause structural damage because it causes the wood material to expand and contract. After the wood has been moistened with water, it’s much more difficult to break. If the water sits for a prolonged time, it could cause an abundance of rot on the wood which can make it break easily.


This problem can be avoided by homeowners and building owners taking immediate action to fix structural damage from moisture-related issues that affect their property after an event like a flood or water-related damage.

Foundation Water Damage

There are numerous reasons why water damage can affect the foundation of a house. Although not all water issues result in structural damage, it’s critical to repair foundational problems in the quickest time possible to prevent structural damage.

The water damage from foundations can lead to many different problems based on how it’s dealt with. It can lead to serious structural damage if the issue isn’t treated quickly.


Roof Water Damage

As with foundation water damage roof water damage is quite common following natural disasters. Roof damage can lead to roof leaks as well as damage the foundations of a house or the foundation of a home.

Leaking roofs can be extremely costly and can have significant drawbacks. A leak on the roof can result in mold and mildew to grow, which can cause death. A leaky roof can cause damage to the roof truss system and cause structural damage to the roof.

Leaks in the ceiling can cause your rafters’ to degrade and soften if you do not address them immediately. Damage to your roof can result from electrical faults, which can lead to the possibility of an electric fire. These are all good reasons to have roof water damage dealt with immediately following a flood, or other sudden damage.

HVAC Water Damage

Your home could be damaged by structural damage if the HVAC system is not working properly or the wrong equipment is put in place. Your business and home at risk in the absence of HVAC. It is possible for mold to grow and result in a range of very serious health problems.

Damage to pipes caused by water

Damage to pipes typically caused by a ruptured pipe in your home. Once you have determined that there’s been a leak, it’s important to seek out professional assistance to stop the water and ensure that it doesn’t cause structural damage.

A ruptured pipe can result in severe damage. If your pipes fail and water enters your home, causing extensive damages and necessitating water damage repair – which can result in structural damage.

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

What is the price of cleaning up water damage?

Water damage restoration cost per square foot

Based on the square feet, water damage repairs and cleanup expenses vary. The following breakdown of pricing can be obtained from National Flood Services for each square foot

  • Clean water category 1: $3.75/sq. Ft.
  • Category 2 gray water: $4.50/sq. ft.
  • Category 3 black water: $7/sq. Ft.

Does water damage get insured by the homeowner’s insurance?

If the cause was sudden and unintentional, homeowners insurance policies typically cover the damage. The Insurance Information Institute states that homeowners insurance can provide for the repair or replacement of windows that have been damaged however, it does not cover damage caused by negligence.

Neglect can be described as damage to an object or surface that results from exposure, poor maintenance or general deterioration. According to the US-based Insurance Information Institute, homeowners insurance does not cover damage due to neglect.

If the damage to your property is the result of a flood, the event will not be covered under a homeowners policy. Flood insurance is mandatory. In certain areas the flood policies are demanded by mortgage companies. Flooding can occur due to storms, flooding the ground and overflowing bodies or the overflowing or surge of bodies such as streams, lakes, rivers and oceans.
