Flooding damage repair – Richmond

Building owners in Richmond experience water damage on a regular basis. Whether you’ve been affected by a natural disaster or a localized catastrophe such as a ruptured pipe, Critical Control is standing by to respond 24/7.

The most common cause of water damage is when water seeps into a building or house through a storm, flood or burst pipe. Sometimes, the damage is obvious and apparent. Other times, it’s more subtle or unreported.

Remediation of water damage is more complex than just drying out the interior. Modern water damage remediation tactics Restoration companies like Critical Control can mitigate damage which previously would have required a complete structural replacement, in the sense of demolish and rebuild.

Water Damage Restoration Guidelines are available Contact an Professional

A lot of times, homeowners or builders attempt to repair water damage with DIY solutions that can be found online. This is inadvisable. Water damage can be controlled according to the established guidelines. These guidelines demand the skills and tools of professionals. The guidelines are laid out in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide exists because of the necessity for professional standardisation in situations involving water damage to homes and buildings as well as the risk they create.

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

There are a lot of reasons why professionals dealing with water damage must adhere to these guidelines. In certain circumstances it is necessary to employ the use of an Indoor Environmental Professional (IEP) is necessary. An IEP is a person with the knowledge and training to evaluate the condition of a place, take samples, run lab tests, then give us advice on the kind of water damage that is likely to occur.

This is particularly important when the building’s occupants might be at risk, is a possibility of negative health effects, the occupants are required to determine the suspected contaminants or any other reason for concern over contamination.

Categories and classes of Water Damage


Restoration projects for water damage are divided into two categories in accordance with the degree of the infiltration of water is.

The class is based on how dirty the water that entered the structure was. Category 1 water is clean like the sink or tub, or burst water supply.

Category 2 water has significant levels of contaminants and can cause illness when it is inhaled or touched. This could include waters that are not readily apparent as a risk such as the effluent from washing machines, or the overflows from toilets.

The water in the category 3 is considered to be extremely contaminated. It may contain toxic, pathogenic or other harmful substances. Usually this means contamination from the backflow of toilets from the trap for toilets and seawater, flooding from rivers and streams or any other water flowing from the exterior of the building. This category of water can include heavy metals, pesticides that are regulated, toxic materials, or substances in it.


You can also utilize the IICRC’s courses to determine how much water has gotten into your property. This is basically a guideline for how saturated a building or house is.

The lowest degree of water absorption and the greatest amount of water is categorized as Class 1. This is when the water comes in contact with approximately five percent or less construction materials which absorb water. This is usually the case that the majority of the building items affected by water are low in evaporation, which means that they don’t soak up and hold water. Examples include concrete, coated or finished wood, plaster , or masonry.

Class 2 indicates that there is significant absorption of water and intrusion. It means that anywhere between 5 to 40% of the combined floor, ceiling and wall is made of low-evaporation materials like wood, concrete, or masonry.

The porous materials like carpet, insulation , and fiberboard which make up Class 3 comprise around 40 percent of wall, floor and ceiling materials, including about 40% in class 3. and also 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 has been deeply trapped in the materials that can not readily absorb water, such as wood, plaster, concrete and bricks and mortar. This is why special drying methods are required and longer drying time.

How do you dry a water damaged Building or Home Building Works


Three ways of removing water from buildings include physical extraction, dehumidification, and evaporate. Eliminating water from liquids is, at a minimum, 500 times more effective than dehumidifiers and airmovers. The faster the structure can dry, the more efficient. The quantity of materials that needs to be extracted will affect both extraction and dehumidification techniques.

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

Forced Evaporation

The remainder of the moisture gets then dried using high-speed air movers once as much water as has been removed.

A submerged object absorbs moisture and water when it’s moistened. The result is that the object becomes damp or wet.

The level of saturation is described as the point at which it is impossible to hold the moisture. The higher the humidity, the more close the air is getting to saturation.

The evaporation process occurs when water molecules change from the state of liquid to a gaseous one. This is known as the process of evaporation.

This means that the object has stopped absorbing water from the atmosphere. This is called the saturation point. Once the saturation point is reached drying will begin.

In the process of evaporation, highly-efficient air mover dry the object from two sides. They generate strong airflow that is directed by a filter system.

A fan that moves air can move between 10 and 20 percent more air than a fan, or an ordinary fan used in the home.

The item is dried using air movers approximately 10 times faster that in the natural environment where no air mover was used.

The high-speed airflow dry the surface of the object and sucks up the water that was drawn away by the air movers.

Using Heat To Assist The Drying Process

Heating is a crucial element of any water damage restoration job. To dry out the materials which have been affected by water, we use a number of different types of heaters.

Electric Heaters: Electric heaters are great to dry jobs which require the use of multiple heat sources. It is possible to run several heaters simultaneously due to their many power ratings.

You can also turn down or turn off the electric heater while the job is being done, and not affect other heaters. To maximize efficiency and lower the cost of energy you can alter the wattage of one heater, while also increasing its capacity.

Since they produce virtually no carbon dioxide and require minimal water Electric heaters are used for restoration projects. The only issue is that they take longer time to get hot, which requires more time to dry process overall.

Hydronic Bioler (TES) Hydronic Bioler (TES), These boilers heat up quickly and emit very little emissions. They can run on natural gas or propane.

Hydronic boilers differ 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 space with these kinds of heaters. They also operate at less temperature, which makes 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 electricity to run electric heaters. They can produce radiant heat and keep your drying area warm without the need of electricity.


To keep buildings and homes dry that are damaged due to flooding, we employ Low Grain Refrigerant (LGR) Dehumidifiers.

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

Apart from removing water out of the air such as an LGR Refrigerant Dehumidifier does this, the home dehumidifier can also remove up to 99% of airborne mold spores in the air, by removing condensation.

Repairing Wood Floor Water Damage

Water damaged hardwood floors need to be cut up to ensure repairs can be made starting from the subflooring up.

First, damaged subflooring needs to be removed and replaced. After that, the hardwood flooring damaged need to be sanded or replaced. In order to ensure a uniform appearance the floors must be sanded and restored after the repairs are completed.

Carpets are vulnerable to water damage

Floods can cause significant damages to your house and make it difficult and expensive. Even if the water is eliminated from the region immediately, there’s the possibility that you’ll have to replace your flooring eventually.

After spending time and money restoring your home to pre-flood condition, it would be devastating to find that the final results leave some things to be desired.

Because of this, it is crucial to determine the severity of the damage as soon as possible. First thing to do is determine if the affected part requires replacement. It is possible to wash the carpet and then use it after drying. This can eliminate worries about the growth of mildew or persistent odors.

Salvaging Carpet After a Water Damage Event

There could be staining on your carpeting if the damage to your carpet was severe. In some cases, you may need to replace your flooring to remove the stain. An odor that is persistent and strong may also be the reason to get your carpet replaced. If this is the case it is likely that you’ll have to replace the padding and carpet.

The next step to determine whether or not it is necessary to replace your carpet is to assess if the floor is able to be professionally cleaned and dried. A professional service can assist you in determining how severe the damage was. We can determine if your carpet should be replaced or saved. If your carpet is in poor shape, some drying methods can cause further damage to it.

A few of the factors that determine whether or whether the padding and carpet require replacement are:

Are your carpets dry, cleaned and disinfected professionally?

If the padding underneath your carpet is damaged, it could affect the length of time your carpet can last. Although your carpet might have been dried immediately, the possibility of mildew development is present if the padding beneath it is not dried as well.

Professional carpet cleaning company is the most effective way to ensure your carpet is dry and clean following a flood. Once the company has completed their job, you’ll be capable of making an informed decision about the state of your carpeting and decide whether or not you need to change it.

Drywall that has been damaged by water

The extent of damage determines the nature and technique of repair. Repairing water damage may be as easy as taking out the drywall portion and then cleaning the affected area and then replacing it.

On the other hand of the coin, severe damages could necessitate a total wall replacement, which includes the wall studs as well as fiberglass insulation.

There are spores of mold in drywall damaged by water that is difficult to remove. Most of the time the drywall will need to be replaced. We utilize moisture testing tools that allow us to determine the extent to which moisture has become. This allows us to identify the areas that are damaged and limit costs to areas that need to be repaired.

Water also causes structural damage, as it causes the wood to expand and contract. It is easier to break wood when it has been moistened by water. If the water is left to sit for a prolonged time, there can be an abundance of rot in the wood that can make it break easily.


In order to counteract this issue, it’s important for building owners and homeowners to address structural damages from moisture-related problems with their home immediately following the water or flood incident.

Foundation Water Damage

There are a variety of reasons that water damage could affect a foundation of a house. While not all water issues can lead to structural damage, it’s crucial to fix foundational problems as quickly as you can to prevent further structural damage.

Foundation water damage can cause many different problems depending on how it is handled. If the issue isn’t taken care of quickly, it could result in structural damage that is severe.


Roof Water Damage

As with foundation water damage roof water damage is also very common after natural disasters. Roof damage can cause roof leaks, and can also cause damage to the foundations of a house or the foundation of a home.

Leaking roofs are extremely expensive and could have major drawbacks. A leak on the roof can result in mold and mildew to develop, which could cause death. The leaks in the roof could also result in damages to the roof truss.

If you don’t take care to address leaks in your ceiling right away they could cause your rafters to degrade and become soft. Electrical faults are also common in the case of roof water damage that can lead to an electrical fire. These are all good reasons to have your roof water damage repaired swiftly following a flood or other unexpected damage.

HVAC Water Damage

If your HVAC system begins to fail or brand new equipment becomes inoperable, it can result in structural damage to your home. You are putting your business and home at risk in the absence of HVAC. Mold growth can occur and lead to a number of very serious health problems.

Pipe water damage

Pipe water damage is usually caused by a ruptured pipe in your home. If you’ve determined there is leak, it’s crucial for you to contact a professional to stop the water and ensure that it doesn’t cause structural damage.

Burst pipes can cause a amount of damage. When your pipes break and water enters your home, causing severe damage and requiring water damage repair – an event that could bring with it structural damages.

When you see water damage to your pipe that is not repaired stop the water supply.

What is the cost of restoring water damaged?

Water damage restoration cost per square foot

Repair and cleanup costs will vary depending on how many square feet you own. National Flood Services has the below pricing breakdown per square foot.

Can Water Damage be covered By the Homeowner’s Insurance?

If the cause was sudden and unintentional the homeowners insurance policy typically cover the damage. According to the Insurance Information Institute, homeowners insurance may cover repair or replacement of a broken window, but not when the damage occurs as a result of negligence.

Neglect can be described as damage to a surface or an object that is the result of exposure, inadequate maintenance, or general degradation. The Insurance Information Institute in the USA declares that homeowners insurance does not cover the damage caused by negligence.

If the water damage resulted from a flood, the event will not be covered under a homeowners policy. Instead, a flood insurance policy would be required. Mortgage lenders may require flood insurance in some areas. Flooding may occur as a result of storms, ground that is saturated to the point of flooding or overflowing bodies of water such as lakes, rivers, ponds oceans, streams in combination with high winds.
