Flooding damage repair – Walnut Creek

Property owners in Walnut Creek experience flood damage regularly. Whether you’ve experienced a natural disaster or a localized catastrophe such as a fire suppression activation, Critical Control is standing by to respond 24/7.

If a storm, flood, or burst pipe causes water to seep into a home or structure water damage can occur most of the time. Sometimes the damage is evident and apparent. In other instances, it’s hidden or not reported.

Water damage remediation is much more complicated than just drying the interior. With modern professional methods for water damage restoration, often restorers like Critical Control can mitigate damage which previously would have required complete reconstruction of the structure, or in terms of demolition and rebuild.

Water Damage Restoration Guidelines are readily available for your reference. Call for a Professional

Many times, homeowners or builders attempt to repair water damage by using DIY methods that can be located online. This is a mistake. There are guidelines for dealing with water damage , and they call on the equipment and expertise of professionals. The guidelines are laid out in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide is required to ensure professional standardisation of situations involving water damage to buildings or homes, and the risk associated with it.

The IICRC guidelines aid restoration experts such as Critical Control to evaluate the severity and type of damages on every project.

These guidelines are essential for water damage professionals. In certain circumstances there are situations where an Indoor Environmental Professional (IEP) is essential. An IEP is a person who has the skills and training to evaluate a site for contamination collect samples, perform lab tests, then give us advice on the nature of the water damage.

This is crucial when the building’s occupants are in danger or there is concern about contamination.

Categories and classes of Water Damage


Restoration projects for water damage can be classified into two types in accordance with the degree of the infiltration of water is.

The water entering the building was classified based on its level of contamination. Category 1 water is clean like a tub or sink or a water source that bursts.

Category 2 water has significant levels of contaminants and can cause illness when it is inhaled or touched. These include sources that are not usually considered to be an issue, like the discharges from washing machines, or overflows from toilets.

Category 3 water can be classified as extremely polluted. It could be contaminated by toxic, pathogenic or other hazardous substances. It can be caused by sewage backflows, leaks in toilet traps, and floods of water from rivers and streams. This category of water can contain heavy metals, pesticides, regulated materials or toxic substances in it.


The IICRC has also established classes we use in determining the level of water intrusion on your property. This is basically setting guidelines for the level of saturation of the home or building.

Class 1 means the least amount of absorption and water. This happens the case when water comes in contact with less than 5% construction materials that absorb water. This is usually the case where most of the materials affected by water are low evaporation. This means they don’t soak up and hold water. Concrete, finished/coated wood, plaster or masonry.

Class 2 refers to absorption of water and intrusion. It is approximately 5 up to 40% of combined floor, wall and ceiling consist of low evaporation materials such as plaster, concrete, wood or the masonry.

The porous materials, like carpet, insulation and fiberboard that comprise the class 3 make up around 40% of floor, wall and ceiling materials, with approximately 40% of the materials in Class 3. and other materials that don’t take in a lot of water, such as concrete or cement have not been negatively affected.

The water has been absorbed into substances like concrete as well as wood, plaster, and even wood that are classified as Class 4. This means that it requires longer drying times and special drying techniques.

How do you dry a water damaged building or house


Physical extraction, dehumidification and evaporation are the three main methods to remove water from a building. Eliminating liquid water is, at a minimum, 500 times more effective than dehumidifiers and air movers. The quicker the structure dries the more efficient. The extraction method and the dehumidification process will be affected by how much material is being removed.

Professionals dealing with water damage utilize a variety of extraction methods. We make use of a variety of equipment, such as self-propelled and subsurface extraction tools.

Forcible Evaporation

The remainder of the moisture gets dried with high-velocity air movers after as much water as possible is taken away.

Submerged objects absorb water and moisture once it’s moistened. The substance is then damp or wet as a result.

The level of saturation is referred to as the point where it becomes impossible to contain any more moisture. A higher humidity indicates that the air is getting closer to saturation.

The evaporation phase is when water molecules change from a liquid state to a gaseous form. This is referred to as evaporation.

In this way it is does not absorb any more moisture from the atmosphere. This is called the saturation point. When saturation is reached, the drying process begins.

High-efficiency air movers dry the object on two sides during the evaporation phase. They generate a large airflow across the entire surface which is directed through a filter system that covers the entire surface of the object.

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

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

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

Use heat to assist the drying process.

Heating is a crucial element of any water damage restoration task. We make use of a variety heaters to dry materials that are damaged by water.

Electric Heaters: These heaters may be used for drying jobs which require multiple sources of heat. You can run multiple heaters simultaneously due to their numerous Wattages.

It is also possible to turn off or turn off the electric heater when the task is done, without affecting other heaters. This means that you can turn one heater down while increasing the wattage of another to maximize efficiency, and decrease your expenses for energy.

Electric heaters are a common feature in restoration projects since they generate virtually no emissions and use minimal amounts of water. The only issue is they take longer to heat up, requiring more time to dry process overall.

Hydronic Bioler (TES) They are also extremely efficient in heating up quickly and generating low emissions. They can be powered by propane or natural gas.

Hydronic boilers differ from electric heating in that they don’t make use of forced air to distribute heat. Therefore, it may be difficult to evenly heat a large area with these types of heaters. They also run at an lower temperature, making ideal for drying projects which require ceilings and walls to be left unattended.

In the event that electric heaters can’t be utilized, hydronic boilers can typically be utilized. They can generate radiant heat, and they can keep your drying space warm without the need for an electrical source.


To dry houses and buildings which have suffered damage due to water damage, we use Low Grain Refrigerant (LGR) Dehumidifiers.

The LGR Home Dehumidifier can draw 170 pints of moisture from damp structures which have suffered massive water damage in just 24 hours.

Apart from removing water from the air, like an LGR Refrigerant Dehumidifier does, the home dehumidifier will also eliminate as much as 99% of airborne mold spores the air, by removing condensation.

Repairing Hardwood Floor Water Damage

Water damaged hardwood floors need to be removed so that repairs can be made from the subflooring upwards.

Drywall that has been damaged by water

The extent of damage will determine the type and method of drywall repair. Water damage repair can be as easy as removing a section of drywall, cleaning it, and after that, replacing it.

On the other side of the coin, severe damage could require a complete wall replacement, which includes walls studs and fiberglass insulation.

Mold spores can be found in water damaged drywall that is difficult to remove. In the majority of cases the drywall needs to be replaced. We utilize moisture testing tools that help us determine the extent to which moisture has become. This allows us to identify areas of damage and limit costs to areas that need to be repaired.

The water can also cause structural damage by causing the wood material to expand and shrink. It is easier to break wood if it has been moistened with water. If the water is left to sit for a lengthy time, it could cause a significant amount of rot in the wood that can make it break easily.


To avoid this problem, it’s essential to homeowners and property owners to fix structural damage from water-related issues with their property immediately after a flood or water damage occasion.

Water Damage to the Foundation

The damage caused by water to a house’s foundation can occur for many reasons. Although not all water problems cause structural damage, it is important to correct foundational issues as soon as possible to avoid further structural damage.

Water damage to the foundation can trigger many different problems in the manner it is handled. It can lead to serious structural damage if it isn’t treated quickly.


Roof Water Damage

As with foundation water damage roof water damage is also quite common following natural catastrophes. As well as causing roof leaks, roof damage can also cause issues with the walls and foundations of a construction.

Roof leaks can be very costly and might have significant disadvantages. The roof’s leaks could cause mold to grow that could be fatal. Leakage in the roof can also cause damages to the roof truss.

Leaks in your ceiling could cause your rafters’ to degrade and soften if you do not take action immediately.
