When a storm, flood or burst pipes cause water to get into a home or structure, water damage occurs more often than not. Sometimes the damage is evident and evident. Other times, it’s hidden or not reported.

Water damage remediation is much more complicated than just drying the interior. Modern methods for water damage restoration, often restorers like Critical Control can mitigate damage that previously would have required a complete structural replacement, in terms of demolition and rebuild.

Water Damage Restoration Guidelines are in place and you can call a Professional

A lot of times, property or home owners attempt to address water damage with DIY solutions that can be found on the internet. This is not advisable. The management of water damage is by following established guidelines. These guidelines demand the skills and tools of experts. The guidelines are set forth in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide exists because of the necessity for professional standards in cases involving water destruction to buildings and homes and the risks they present.

The IICRC guidelines help restoration experts like Critical Control to evaluate the category and class of damage on each project.

These guidelines are crucial for water damage professionals. In some situations it is necessary to employ the use of an Indoor Environmental Professional (IEP) is essential. An IEP is someone with the knowledge and training to evaluate an area for contamination collect samples, perform lab tests, then give us advice on the type of water damage.

This is crucial in cases where the building’s residents are in danger or are concerned regarding contamination.

Categories and classes of Water Damage


Restoration of water damage projects are classified according to category and class based on the severity of the flood.

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

Category 2 is water that contains significant amounts of contaminants and has the potential to cause illness or discomfort if contacted or consumed. It could include sources that may not normally seem like an issue, like the discharge from washing machines or overflows from toilets.

Category 3 water can be considered to be extremely polluted. It could contain pathogenic, toxic, or any other harmful substances. This usually means contamination from sewage, toilet backflows after the toilet trap or a flood of seawater from rivers and streams or any other source of water that comes from the building exterior. The water in this category could contain heavy metals, pesticides and regulated substances as well as toxic substances within it.


The IICRC has also established classes that we follow in determining the level of water intrusion into your property. This system basically sets guidelines for the saturation of the structure or the home.

The lowest degree of water absorption and the greatest amount of water is categorized as Class 1. This is when the water is in contact with around 5% or less with construction materials that absorb water. This is because the majority of substances that are affected by water don’t hold or absorb water. Concrete and masonry, as well as plaster and coated or finished wood are only several examples.

Class 2 is a term used to describe water absorption and intrusion. It means that anywhere between 5% to 40% of the combined floor, ceiling and wall is constructed of materials with low-evaporation, such as plaster, concrete, wood, or bricks and mortar.

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

Class 4 refers to the fact that water has become deeply trapped in the materials that can not readily absorb water, such as concrete, wood, and bricks and mortar. This requires more drying time and special drying techniques.

How to Dry a Water damaged building or house


Three ways of removing water from buildings include physical extraction, dehumidification, and evaporate. Eliminating water from liquids is typically 500 times more efficient than dehumidifiers and airmovers. The faster the structure dries the more effective. The extraction method and the dehumidification process will be affected by the amount of much stuff is being extracted.

Professionals dealing with water damage employ various extraction methods. Our tools include subsurface tools, wands as well as self-propelled tools and vacuum squeezers.

Forcible Evaporation

After as much water is removed, the remaining moisture is then dried by high-speed airmovers.

A submerged object absorbs water and moisture when it is moistened. The substance is then damp or wet due to this.

The saturation level is known as the point where it becomes impossible to contain any additional moisture. The greater the humidity, the more close the air is to saturation.

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

This means that the object no longer absorbs moisture from the atmosphere. The saturation point is the point of evaporation. As soon as saturation is attained the drying process commences.

High-efficiency airmovers dry the object in two areas in the evaporation phase. They produce strong airflow that is directed by a filter system.

A fan that moves air can move around 10 to 20% more air than a fan, or even a regular fan in your home.

Air movers dry objects approximately 10 times faster than normal conditions, when no air mover is used.

The high-speed airflow dry the surface and draws in the moisture that has been taken out by the air mover.

Utilizing Heat to Aid the Drying Process

Heating is a crucial element of any water damage restoration job. To dry out the materials that have been affected by water, we make use of various kinds of heaters.

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

Electric heat can also be capable of being shut off or reduced while the job is in process, without affecting your other heaters. This means you can reduce one heater while increasing the power of the other to increase efficiency, and decrease your expenses for energy.

Electric heaters are a common feature in restoration jobs because they produce essentially no emissions and require minimal amounts of water. They take longer to warm up and need more time for drying.

Hydronic Bioler (TES): These boilers are extremely efficient at heating up quickly yet releasing very little emissions. They can run on natural gas or propane.

Hydronic boilers differ from electric heating as they don’t make use of forced-air heat to distribute heat. This makes it difficult to heat large areas evenly using these heaters. They also run at an lower temperature, making them ideal for drying jobs which require ceilings and walls to be left unattended.

Hydronic boilers are often used in situations where there is no electrical power to run electric heaters. They can produce radiant heat, and they can keep your drying space warm without the requirement of electricity.


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

The LGR Home Dehumidifier is capable of removing 170 pints water from an un-dry structure that is severely damaged by water damage every all day, every hour of the day.

In addition to extracting water out of the air, such as an LGR Refrigerant Dehumidifier does it, the dehumidifier for your home will also get rid of up to 99percent of airborne mold spores in the air, by removing 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.

The subflooring needs to be taken off and repaired before. Then the affected hardwood boards require sanding down or replaced. Once these repairs are complete, the entire floor should be sanded and refinished to ensure uniformity.

Water Damage To Carpeting

Floods can cause severe destruction to your home and can make repairs difficult and expensive. You might need to change your flooring, even if you have taken the water out of the area as quickly as you can.

After investing time and money in restoring your home to pre-flood condition, it would be depressing to discover that the final results leave something to be desired.

In this regard, it is crucial to determine the extent of damage as soon as possible. One of the initial issues that must be resolved is whether the affected region should be replaced. It is possible to clean the carpet and then use it again after drying. This can eliminate worries about mildew growth or persistent scents.

Salvaging Carpet After a Water Damage Event

If the water damage has been very severe, it is possible that you’ll see noticeable staining on your carpet. There are times when you have to replace your flooring to eliminate the stain. An odor that is persistent and strong may also be the reason to change your carpet. If you find this to be the case it is likely that you’ll require replacement of both the padding and carpet.

The next step to determine whether or not you’ll need to replace your carpeting is to determine whether your floor is able to be professionally cleaned and dried. If you have an established company that can handle the cleaning, then you’ll have a better idea of how severe the water damage was. Our team will evaluate the carpet and decide if it should be replaced or re-usable. If your carpet is in poor shape, some drying methods could further harm it.

Many factors determine the need for padding or carpet is a good idea to replace it.

Do your carpets get professionally cleaned, dried, and disinfected?

If the padding beneath your carpet has been damaged, it could affect the length of time your carpet is clean. Although your carpet has been dried in a short time, mildew growth may still be present if the padding underneath is not dried.

The safest way to ensure that your carpeting is properly cleaned and disinfected following an event of flooding is to engage an expert carpet cleaning service. After the job is completed then you’ll have the ability to make an informed decision about the state of your carpet. It is also possible to decide whether you want to replace it.

Drywall damaged by water

The severity of the damage will determine the nature and way to repair drywall. Repairing water damage may be as easy as taking out some drywall and then cleaning the affected area and then putting it back.

The opposite of this is that serious damage could require whole-wall replacement including the wall studs and fiberglass insulation.

Drywall that has been damaged by water often contains mold spores that cannot be removed easily. In most cases the drywall will need to be replaced. We use moisture testing tools to measure the amount of moisture. This allows us to isolate areas of damage and keep costs restricted to areas that need to be repaired.

It also causes structural damage because it causes the wood to expand and contract. After the wood has been moistened by water, it becomes a lot easier to break. If the water sits for a lengthy time, there can be an abundance of rot within the wood which can make it break easily.


To prevent this issue, it’s important for building owners and homeowners to address structural damages from moisture-related problems with their property immediately after an event like a flood or water damage occasion.

Water Damage to the Foundation

Water damage to a house’s foundation can happen due to many reasons. While not all water concerns result in structural damage, it is critical to repair foundational problems as quickly as possible to avoid potential structural damage.

Foundation water damage can lead to many different issues based on the way it’s treated. It can cause severe structural damage if not addressed quickly.


Roof Water Damage

Water damage to roofs can be caused by natural catastrophes, just like foundation water damage. Roof damage can cause roof leaks as well as damage the foundations of a house or house.

Leaking roofs are extremely costly and can have significant drawbacks. Leakage in the roof could lead to mold growth that could be fatal. Leaks in the roof may also cause damages to the roof truss.

Leaks in your ceiling could cause your rafters to deteriorate and become soft if you don’t deal with them right away. Water damage to the roof could result from electrical issues that can cause an electric fire. All of these are good reasons to get roof water damage repaired swiftly following a flood or other damage that is unexpected.

HVAC Water Damage

If your HVAC system starts to fail or brand-new equipment becomes defective, it could cause structural damage to your house. If you do not have HVAC you’re exposed to the interior of your business or home to all sorts of issues. Mold growth can occur and result in a range of very serious health problems.

Damage to Pipes from Water

Pipe water damage is usually 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 cause structural damage.

Burst pipes can cause a number of damages. When pipes are damaged they can let water into your home, creating extensive damages and necessitating water damage repair – which can bring with it structural damages.

If you spot broken pipe water damage close off the water supply.

What’s the price to repair the damage caused by water?

Water damage restoration cost per square foot

Depending on the square foot the repair and cleanup costs vary. National Flood Services has the below pricing breakdown per square foot.

Is water damage insured by the homeowner’s insurance?

If the cause of the damage was accidental and sudden homeowners insurance policies generally cover it. According to the Insurance Information Institute, homeowners insurance policies can cover repair or replacement for a damaged window, however, not if the damage is a result of neglect.

Neglect is defined as damage to a surface or object that is the result of 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 water damage resulted from a flood, the event is not covered under the homeowners insurance. Instead, a flood insurance policy is necessary. In some regions the flood policies are demanded by mortgage companies. Flooding can happen as a result of storms, over-saturated ground, flooding or overflowing bodies of water like lakes, rivers, ponds oceans, streams when combined with strong winds.
