Flood damage restoration service – Berkeley

Building owners in Berkeley experience water damage regularly. Whether you’ve been affected by a natural disaster or a localized catastrophe such as a building flood, Critical Control is standing by to respond 24/7.

The most common cause of water damage is when water enters a building or residence via a flood, storm, or burst pipe. Sometimes the damage is evident and apparent. Other times, it’s hidden or not reported.

It’s more complex than simply drying the interior to fix water damage. Modern professional methods for water damage remediation like Critical Control, can often minimize damage that otherwise would need a total structural replacement.

Water Damage Restoration Guidelines are in place so call a Professional

Oftentimes, home or building owners attempt to address water damage using DIY solutions found on the internet. This is a mistake. The management of water damage is by following established guidelines. These guidelines require the knowledge and skills of experts. These guidelines are detailed in what is known as IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guideline is essential to ensure that there is a professional standardisation for instances involving water damage to houses or buildings, and the risks associated with it.

Critical Control, a restoration company, can use the IICRC guidelines to determine the extent and type of the damage each project has sustained.

There are many reasons that water damage professionals need to follow these guidelines. There are certain situations that require our bringing in an Indoor Environmental Professional (IEP). An IEP is an individual who has the skills and training to evaluate an area for contamination and take samples, conduct lab tests and offer us suggestions on the nature of the water damage.

This is crucial when the building’s residents are at high risk or have concerns about contamination.

Water damage according to types and classes


Restoration projects for water damage can be classified into two types, depending on how extensive the water infiltration is.

The water entering the structure was classified according to its contamination. Category 1 water is clean like an unclean sink or tub, or a water source that bursts.

Category 2 involves water that has high levels of contaminants and is likely to cause illness or discomfort when inhaled or consumed. The sources could be waters that are not readily apparent as a risk such as the effluent from washing machines and spills from toilets.

Category 3 water can be considered extremely polluted. It could be contaminated by toxic, pathogenic, or other hazardous substances. Most often, this is due to contamination by sewage, toilet backflows after the toilet trap or a flood of seawater from streams and rivers, 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 chemicals in it.


The IICRC has also created classes we use in determining the degree of water intrusion into your property. The system is basically a set of guidelines for the saturation of the home or building.

Class 1 is the smallest amount of absorption and water. It is the case the case when water comes in contact with less than 5% the building materials which absorb water. This is the situation in which the majority of substances affected by water have low in evaporation, which means that they aren’t able to absorb and retain water. Examples include concrete, coated or finished wood, masonry or plaster.

Class 2 means that there is substantial absorption of water and intrusion. It means that anywhere between 5 to 40% of the ceiling, floor, and wall are made from low-evaporation substances like plaster, concrete, wood or bricks and mortar.

The porous materials, such as carpet, insulation , and fiberboard which make up Class 3 are approximately 40 percent of wall, floor and ceiling materials, including around 40% in class 3. and also where other materials that do not take in a lot of water, such as concrete or cement have not been adversely affected.

Class 4 indicates that water has been deeply stuck in materials that do not easily absorb water as wood, plaster, concrete and masonry. This requires more drying time and special drying methods.

How to Dry a Water Damaged Home or Building Works


Physical extraction, dehumidification and evaporation are considered three methods to remove water from buildings. Removal of liquid water is at least 500 times more effective than merely having to put up with dehumidifiers or air movers. The quicker the structure dries the more efficient. The extraction method and the dehumidification process are affected by how much material is being removed.

Water damage professionals use an array of extraction techniques. Our tools include tools for subsurface extraction, wands, self-propelled tools, and vacuum squeegees.

Forced Evaporation

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

When an object is moistened or submerged in water it absorbs some moisture or water. In the process, the object becomes damp or wet.

Saturation is the time at which it becomes impossible for air to hold any moisture. More humid means that the air is closer to saturation.

In the evaporation process in which water molecules are ejected from liquid state to gaseous state. This is known as the process of evaporation.

In another 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 process. They produce a powerful airflow over the entire surface, that is controlled through a filter system that covers the entire area of the object.

An air mover moves around 10-20 times more air than a fan , or the typical household fan.

The object is dried using airmovers around 10 times faster than the natural environment where no air mover was employed.

The high-speed airflow dry the surface and draws in the water that was drawn out by the air movers.

Use heat to assist the drying process.

A key component for any water damage restoration work is heat. To dry out the materials that have been affected by water, we employ various kinds of heaters.

Electric Heaters: These heaters may be used to dry jobs that require multiple heating sources. This is due to the fact that they come in a variety of wattages, allowing you to run multiple heaters simultaneously.

You can also reduce or turn off the electric heater as the work is done, and not affect other heaters. This means you can reduce one heater while increasing the wattage of another to maximize efficiency and lower cost of energy.

Since they produce virtually zero emissions and consume very little water, electric heaters are very well-liked for restoration projects. However, the only drawback is that they take longer time to get hot, which requires longer drying time. process overall.

Hydronic Bioler (TES): They are also extremely efficient at heating up quickly, while still producing minimal emissions. They are typically run using propane or natural gas.

Hydronic boilers differ from electric heat as they don’t make use of forced-air heat to disperse heat. This can make it difficult to distribute heat evenly over large areas by using these heaters. They can also be used to dry out jobs that do not require walls or ceilings to be in place.

Hydronic boilers are also often used when there is no electrical power to run electric heaters. Because they are so efficient in producing radiant heat, they are able to keep your drying space warm, even without an electrical power source.


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

The LGR Home Dehumidifier can remove 170 pints of water from a damp building which has been badly affected by water damage every all day, every hour of the day.

The home dehumidifier can extract water from the air the same way it does an LGR Refrigerant Dehumidifier. It can also remove the 99 percent or more of airborne mold spores by removing condensation.

Fixing Wood Floor Water Damage

It is important to remove water damaged hardwood floors to ensure that repairs can be made by removing the subflooring.

The subflooring must be taken off and repaired before. The hardwood floors damaged need to be replaced or sanded. In order to ensure a uniform appearance, all floors should be sanded, then repaired after these repairs have been made.

Carpets Damaged by Water

Floods can cause significant damages to your house and can make repairs costly and difficult to repair. Even if water is taken away 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 find out that your home isn’t in the best condition after spending many hours and dollars to fix it.

It is vital to identify the extent of damage as soon as you can. First thing to do is determine if the affected area requires replacement. It is possible to wash the carpet and use it again after drying. This will eliminate any worries about mildew growth or persistent scents.

Salvaging Carpet After a Water Damage Event

If the water damage is very extensive, it is possible that you’ll notice marks on your carpet. In some cases the only option to remove the stains is to replace the flooring. A persistent, strong odor can also be an indication to replace your carpeting. If you find this to be the case it is likely that you’ll need to replace both your carpet and padding.

The next step to determine whether or not it is necessary to replace your carpeting is to find out whether the flooring can be dried and cleaned professionally. If you can have an established company that can handle the cleaning, then you will have a better understanding of how serious the damage was. Our firm will examine your carpet and determine whether it is best to replace it or re-usable. If the carpet you have is already damaged, a few drying techniques can further damage it.

Many factors determine the decision of whether padding or carpet is a good idea to replace it.

Can your carpets be dried or cleaned professionally?

The carpet’s ability to remain clean can be affected if the padding beneath it has been damaged. Even though your carpet may be dry, the possibility of mildew growth is still present if the padding beneath isn’t dried as well.

A professional carpet cleaning service is the most effective way to ensure your carpet is dry and clean after a flood. Once the work is done you’ll be able to make an informed decision about the condition of your carpet. You’ll also be able to determine whether you want to replace it.

Drywall damaged by water

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

The flip side of the coin is that serious damage could need to be repaired completely, including walls studs and fiberglass insulation.

Mold spores can be found in water damaged drywall that is difficult to eliminate. In most cases, the drywall will have to be replaced. We use moisture testing equipment that help us determine the extent to which water has grown. This allows us to identify damaged areas and limit the cost to only the areas that are damaged.

Water can cause structural damage as well, as it causes the material to expand or shrink. It is easier to break wood when it has been moistened with water. The wood may be brittle if kept in the water for too long.


This problem can be avoided by homeowners and building owners making immediate changes to repair the structural damage caused by moisture-related issues with their property after flooding or other water-related damage.

Water Damage to the Foundation

There are many reasons water damage can affect a foundation of a house. While not every water issue can lead to structural damage, it is important to fix foundational problems as quickly as you can to prevent further structural damage.

Foundation water damage can cause a variety of problems depending on how it’s treated. If the damage is not treated quickly, it could cause serious structural damage.


Roof Water Damage

Like foundation water damage, roof water damage is very common after natural catastrophes. In addition to creating roof leaks damage can also result in problems with the walls or foundations of a the building.

Leaking roofs can be extremely expensive and could have major drawbacks. A leak in the roof may cause mold and mildew to develop, which could cause death. A roof that is leaky could harm the roof truss system, which can cause structural damage to the roof.

If you don’t address leaks in your ceiling right away they could cause your rafters to degrade and become soft. Damage to your roof can result from electrical issues which could lead to the possibility of an electric fire. All of these are good reasons to get roof water damage repaired quickly following a flood or other damage that is unexpected.

HVAC Water Damage

If your HVAC system begins to fail or brand new equipment becomes inoperable, it can result in the structure of your house. Your business and home at risk in the absence of HVAC. The growth of mold can cause a variety of very serious health problems.

Pipe water damage

Pipe water damage is usually caused by a ruptured pipe in your home. When you’ve discovered that there is a leak, it’s important to seek out professional assistance to stop the flow of water and make sure it doesn’t lead to structural damage.

The burst of pipes can cause lot of damage. When pipes are damaged they can let water into your home, creating extensive damage and requiring repair of water damage. This is which can bring with it structural damages.

Shut off the water supply, and then contact an experienced IICRC-certified professional from a company for water restoration like Critical Control as soon as you spot broken pipe water damage.

How much does it cost to fix water damage?

Water damage restoration cost per square foot

Water damage cleanup and repair cost will differ based on how many square feet you have. The following pricing breakdown is available at National Flood Services for each square foot

Will Water Damage Be Covered By Homeowner’s Insurance?

If the cause of the damage was accidental and sudden the homeowners insurance policy will usually cover it. According to the Insurance Information Institute, homeowners insurance may cover repair or replacement of a broken window, however, not if the damage is a result of neglect.

Damage from neglect may be described as wear and tear on a surface or object because of exposure, lack of regular maintenance or general wear and tear. The Insurance Information Institute in the US states that homeowners insurance does not cover the damage caused by negligence.

If the damage to your property results from a flood, the event will not be covered under homeowner’s insurance. Instead, a flood insurance policy would be required. In some regions where flood insurance is required, it’s usually by mortgage lenders. Flooding can occur because of storms, over-saturated ground, overflowing or surging bodies of water such as rivers, ponds, lakes, streams, oceans when combined with strong winds.
