Flood damage restoration service – Kentfield

Property owners in Kentfield suffer 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.

Water damage is more common when water seeps into a building or residence by way of a flood, storm, or ruptured pipe. Sometimes the damage is overt and evident, while other times it’s subtle or even hidden.

The process of repairing water damage is more complex than simply drying out the interior. With the most modern techniques for water damage remediation, often restorers like Critical Control can mitigate damage that previously would have required a complete reconstruction of the structure, or in the sense of demolish and rebuild.

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

Many times, homeowners or builders try to fix water damage by using DIY methods that can be discovered on the internet. This is not advisable. Water damage can be controlled in accordance with established guidelines. These guidelines demand the skills and tools of professionals. These guidelines are available in the IICRC Standard Reference Guide, or Professional Water Damage Restoration book. This guide is required to ensure that there is a professional standardisation for scenarios involving water damage houses or buildings, and the risks associated with it.

The IICRC guidelines aid restoration experts such as Critical Control to evaluate the category and class of damage on each project.

There are really important reasons why water damage experts should follow these guidelines. In some situations, an Indoor Environmental Professional (IEP) is essential. An IEP is a person who has the expertise and knowledge to assess a site for contamination, take samples, run lab tests, then offer us suggestions on the type of water damage.

This is especially important in situations where the occupants of the building could be at risk, are a chance of adverse health consequences, or the occupants express a need to identify the suspected contaminants or have another reason for concerns about contamination.

Categories and Classes of Water Damage


Restoration projects for water damage are classified by category and class based on the severity of the invasion of water.

The class has to do with how dirty the water that enters the structure has been. Category 1 water comes from a clean source like an unclean sink or tub, or a burst water supply.

Category 2 water contains significant levels of contaminants and could cause illness if it is inhaled or touched. This could include water that is not obvious as a threat like the discharge from washing machines, or the overflows from toilets.

The water in Category 3 is highly contaminated meaning that it can contain pathogenic, toxic or any other harmful agent in it. This can be caused by backflows of sewage, leaks in toilet traps, and floods of water from rivers and streams. This kind of water could contain heavy metals, pesticides that are regulated, toxic materials, or chemicals in it.


It is also possible to use the IICRC’s courses to determine how much water has penetrated your property. The system is basically a set of guidelines for the level of saturation of the home or building.

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

Class 2 signifies that there is substantial absorption of water and intrusion. It is approximately 10% up to 40% of the combined ceiling, floor and wall comprised of low-evaporation materials like plaster, concrete, wood or masonry.

The porous materials, such as carpet, insulation and fiberboard that comprise Class 3 comprise around 40 percent of wall, floor and ceiling materials. This includes approximately 40% of the materials in Class 3. Other materials such as concrete or plaster that don’t absorb water have not been adversely affected.

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

How Drying a Water Damaged Building or Home Building Works


Three ways of removing water from buildings include physical extraction, dehumidification and evaporation. Eliminating water from liquids is at most 500 times more effective than using dehumidifiers or air movers. The faster the structure can dry, the better. Both methods of extraction and dehumidification will be affected by the amount of much of the material is extracted.

Water damage experts employ a variety of extraction methods. We employ a range of equipment, such as self-propelled and subsurface extraction tools.

Forced Evaporation

After as much water has been removed, the remaining moisture is dried with high-speed airmovers.

When an object is moistened or submerged in water it absorbs a portion of the moisture or water. As a result, the material gets dampened or wet.

The level of saturation is referred to as the point at which it becomes impossible to contain any additional moisture. The higher the humidity, the more close the air is to saturation.

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

In another way the object does not absorb any more moisture from the atmosphere. This is called the saturation point. When saturation is attained the drying process commences.

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

Air mover is able to transport between 10 and 20% more air than a fan, or even a regular fan in your home.

The object is dried using airmovers around 10 times faster than natural conditions in which there was no air movement.

A high-velocity airflow is able to dry the surface of the object and sucks up the water that was pulled out by the air movers.

Utilize heat to aid in the drying process

The element of heat is crucial to the success of any restoration task. To dry out materials damaged by water, we employ various types of heaters.

Electric Heaters These heaters are perfect for drying jobs which require the use of various heat sources. They come in a variety of wattages, allowing you to operate multiple heaters at once.

It is also possible to turn off the electric heating as the work is done, and not affect other heaters. This means you can lower one heater, while increasing the wattage of another one to improve efficiency, and decrease your energy costs.

Electric heaters are a common feature in restoration work since they emit virtually no emissions and use minimal amounts of water. They take longer to heat up and require more time to dry.

Hydronic Bioler (TES) Hydronic Bioler (TES) These boilers are able to heat quickly and emit very little carbon dioxide. They can be powered by natural gas or propane.

Hydronic boilers are different from electric heat as they don’t make use of forced-air heat to distribute heat. This can make it difficult to evenly heat large areas using these heaters. They are also able to dry jobs that do not require ceilings or walls to be in the same place.

If electric heaters are not utilized, hydronic boilers can frequently be employed. They can produce radiant heat, and they can keep your drying area warm without the requirement of an electric source.


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 water from damp structures that have experienced massive water damage in just 24 hours.

In addition to removing water out of the air, as a LGR Refrigerant Dehumidifier does this, the home dehumidifier can also eliminate up to 99% of airborne mold spores the air by eliminating condensation.

Fixing Wood Floor Water Damage

Hardwood floors damaged by water have to be ripped up so repairs can take place from the subflooring upwards.

Subflooring that is damaged first has to be removed and repaired. The damaged hardwood boards require sanding down or replaced. In order to ensure a uniform appearance, all floors should be sanded down and refinished after these repairs are completed.

Carpets Damaged by Water

We will be able to evaluate whether or not your carpet should be replaced or salvaged. Remember that some methods used for drying can also further damage the carpet if it is already in poor condition.

Several factors will influence the need for padding or carpet is a good idea to replace it.

  • What percentage of water did you get on your carpet?
  • How long did the water sit on the carpet?
  • What was the source of water?

Do your carpets need to be dried and cleaned, or disinfected and cleaned professionally?

The carpet’s ability to stay clean can be affected if the padding underneath it is damaged. Even though your carpet may be dry however the risk of mildew development is present if the padding beneath isn’t dried too.

Professional carpet cleaning service is the best option to make sure your carpeting is clean and dry after an event of flooding. Once the company has completed their job, you’ll be capable of making an informed decision about the condition of your carpet and decide whether or not you need to replace it.

Drywall that has been damaged by water

The severity of the damage determines the kind and technique of repair. Repairing water damage could be as simple as removing some drywall and cleaning the area and then replacing it.

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

Mold spores can be found in damaged drywall, which is hard to get rid of. So in most cases the drywall needs to be replaced. We employ moisture testing tools that allow us to determine where and how extensive the humidity has gotten. This helps us identify damaged areas and limit the cost to only the areas that are damaged.

The water can also cause structural damage, as it causes the wood material to expand and shrink. It is easier to break wood if it has been moistened by water. If the water sits for a long period of time, it could cause 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 water-related issues with their property immediately after a flood or water damage event.

Foundation Water Damage

Water damage to a house’s foundation can be caused by many reasons. While not all water issues cause structural damage, it’s crucial to correct foundational problems as quickly as you can to avoid future structural damage.

The damage caused by water in the foundation could cause many different problems in the manner it is addressed. It can lead to serious structural damage if it isn’t addressed quickly.


Roof Water Damage

Roof water damage can also result from natural disasters as well as foundation water damage. As well as causing roof leaks, roof damage can cause issues with the walls and the foundation of a house or construction.

Roof leaks can be very expensive and could have major drawbacks. Leakage in the roof could lead to mold growth and can be fatal. The leaks in the roof could cause damages to the roof truss.

If you don’t fix leaks in your ceiling immediately, they can cause the rafters to decay and then soften. Electrical problems are also common when it comes to roof water damage which can cause an electrical fire. These are all good reasons to have your roof water damage repaired swiftly after a flood or any other unexpected damage.

Are water damages covered by homeowners’ insurance?

The homeowner’s insurance policies are generally used if the damage is sudden and unintentional. The Insurance Information Institute states that homeowners insurance will provide for the repair or replacement of broken windows however, it does not cover damage caused by neglect.

Damage caused by neglect can be defined as wear and tear of a surface or object due to exposure, insufficient preventative maintenance, or general degradation. According to the US-based Insurance Information Institute, homeowners insurance will not cover damages from neglect.

A homeowner’s policy does not cover water damage caused by flooding. A flood policy is mandatory. In some regions the flood policies are demanded by mortgage companies. Flooding can happen because of flooding, over-saturated ground, and surging or overflowing bodies water such as rivers, ponds, lakes oceans, streams in combination with high winds.
