Water damage remediation – Greenbrae

Building owners in Greenbrae get hit with flood damage regularly. Whether you’ve been affected by a natural disaster or a localized catastrophe such as a fire suppression activation, Critical Control is standing by to respond 24/7.

When a storm, flood, or burst pipe causes water to get into a home or structure water damage can occur most of the time. Sometimes the damage is evident and obvious. Other times, it’s more subtle or unreported.

It’s more difficult than simply drying the interior to repair water damage. Modern methods for water damage restoration typically restorers such as Critical Control can mitigate damage which would in the past would have required complete reconstruction of the structure, or in other words, demolish and rebuild.

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

Many times, homeowners and builders attempt to repair water damage by using DIY solutions located on the internet. This is not a good idea. Water damage can be controlled by following the established guidelines. These guidelines call for the knowledge and skills of experts. The guidelines are laid out in what is known as IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide is necessary to ensure the professional standardisation of situations involving water damage to structures or homes, as well as the risk associated with it.

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

These guidelines are crucial for professionals dealing with water damage. In some situations, an Indoor Environmental Professional (IEP) is essential. An IEP is professional with the experience and knowledge to examine the health of a building, collect samples, get lab testsand help us determine the kind of water damage.

This is especially important when the building’s occupants might be at risk, there is a possibility of negative health consequences, or the occupants express a need to identify the suspected contaminants or any other reason that there might be concerned about contamination.

Water damage according to types and classes


Projects for water damage restoration are classified into two categories in accordance with the degree of the infiltration of water is.

The water that enters the structure was classified according to its level of contamination. Category 1 water is clean such as an unclean sink or tub, or a burst water supply.

Category 2 is water that has significant levels of contaminants and has the potential to cause discomfort or illness if contacted or consumed. These sources can be water that isn’t obvious as a threat like the discharge from washing machines or overflows from toilets.

Water in Category 3 can be classified as highly contaminated. It may contain toxic, pathogenic, or any other hazardous substances. This could be due to backflows of sewage, toilet trap leaks, and the flooding of rivers and streams. This category of water can have pesticides, heavy metals that are regulated, toxic materials, or substances in it.


The IICRC has also established classes we use in measuring the amount of water intrusion to your property. This is basically an outline of how saturated a building or home ought to be.

The lowest level of water absorption , and the highest amount of water is classified as Class 1. It is the case the case when water comes in contact with less than 5% building materials which absorb water. This is because most materials that are affected by water won’t absorb or hold water. Concrete or plaster, masonry and coated or finished wood are only several examples.

Class 2 indicates that there is significant absorption of water and intrusion. This is about 10% up to 40% of the combined ceiling, floor and wall consist of low evaporation materials like plaster, concrete, wood or the masonry.

Class 3 is the term used to describe 40% or more of the floor, wall and ceiling surfaces are porous like fiberboard, insulation, carpet, etc. and where other materials that don’t absorb water like concrete or cement have not been adversely affected.

The water has been absorbed into materials like concrete or plaster and wood that are classified as Class 4. This will require more time to dry and special drying methods.

How to dry a water damaged building or house


Three methods for removing water from buildings are physical extraction, dehumidification and evaporate. Eliminating liquid water is at most 500 times more efficient than dehumidifiers and airmovers. The faster the structure can dry, the more efficient. Both extraction and dehumidification methods will be affected by how much stuff is being extracted.

Water damage professionals use an array of extraction techniques. Some of our tools include wands, subsurface extraction tools, self-propelled tools, and vacuum squeezers.

Forcible Evaporation

The remainder of the moisture gets then dried by high-speed airmovers after as much water as is taken away.

Submerged objects absorb water and moisture when it’s wet. The substance gets wet or damp due to this.

The degree of saturation is known as the point at which it is impossible to hold any additional moisture. The higher the humidity, the more close the air is to being saturated.

In the evaporation stage, water molecules jump from liquid state to gaseous state. The process is called evaporation.

This means that the object no longer absorbs moisture from the air. This is known as the saturation point. As soon as saturation is reached, the drying process begins.

In the evaporation phase the highly efficient air movers dry the object from two sides. They create strong airflow which is directed by a filter system.

Air mover can move 10-20 times more air than a fan or an ordinary household fan.

Air movers dry objects around 10 times more quickly than in normal conditions, when no air mover is used.

A high-velocity airflow dries the surface and draws in the water that was drawn away by the air movement.

Make use of heat to help in the drying process.

Heat is an important component of any water damage restoration job. To dry out materials which have been affected by water, we use various kinds of heaters.

Electric Heaters They are ideal to dry jobs that require the use of multiple heating sources. They are available in several different energies, which lets you run multiple heaters simultaneously.

Electric heat is also able to be shut off or reduced while the job is in process, without affecting your other heaters. This means you can turn one heater down while increasing the wattage of another one to improve efficiency and lower cost of energy.

Because they emit almost no emissions and require very less water, electric heaters are very well-liked for restoration projects. They are more difficult to heat up and require longer drying time.

Hydronic Bioler (TES): These boilers are extremely efficient in heating up quickly yet releasing low emissions. They are typically run with propane or natural gas.

Hydronic boilers are different from electric heat because they don’t use forced-air heat to disperse heat. This can make it difficult to heat large areas evenly by using these heaters. They can also be utilized for dry work that does not require walls or ceilings to remain in place.

When electric heaters cannot be utilized, hydronic boilers can frequently be employed. They can generate radiant heat, and they can keep your drying space warm without the need of an electrical source.


We employ low Grain Refrigerant Dehumidifiers (LGR) to keep buildings dry and houses that have suffered water damage.

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

The dehumidifier at home is able to remove water from the air the same way as an LGR Refrigerant Dehumidifier. It can also remove the 99 percent or more of the airborne mold spores through the elimination of condensation.

Repairing Wood Floor Water Damage

Hardwood floors damaged by water have to be removed so that 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. To ensure uniformity the floors must be sanded down and repaired after these repairs have been completed.

Water Damage to Carpeting

Floods can cause significant damage to your home and cause it to be difficult and expensive. You may need to replace your flooring even if you’ve removed the water from the area as quickly as possible.

It’s devastating to discover that your home is not in the best condition after you have spent lots of time and money to fix it.

It is crucial to determine the severity of the damage as quickly as possible. One of the initial issues that must be resolved is whether the affected region should be replaced. There’s a good possibility that the carpet could be cleaned and used once it is dry and the cleaning process can help to eliminate concerns regarding the growth of mildew and the lingering smells.

Salvaging Carpet After a Water Damage Event

If the damage from water is very extensive, it is possible that you will have noticeable marks on your carpet. In some instances, the only way to remove the stains is to replace the flooring. A strong, lingering odor can also be an indication to replace your carpeting. If you find this to be the case, then you will likely have to replace your carpet and padding.

The next step to determine whether or not it is necessary to replace your carpet is to determine if the floor can be dried and cleaned professionally. Professionals will be able to assist you in determining how severe the damage was. Our team will evaluate your carpet and determine if it should be replaced or repairable. If the carpet you have is in poor shape, some drying methods could further harm it.

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

Are your carpets professionally dried, cleaned, and cleaned?

The carpet’s capacity to remain clean is affected when the padding beneath it is damaged. Even though your carpet is dried in a short time, mildew growth may still be present in the padding beneath if it isn’t dried.

Professional carpet cleaning company is the best option to ensure that your carpet is clean and dry after the flood. After the company completes their task, you’ll be in a position to make an informed decision about the condition of your carpet and determine whether or not you need to change it.

Drywall that has been damaged by water

The drywall repair procedure varies based on the extent of the damage. Repairing water damage can be as simple as removing some drywall and then cleaning the affected area and replacing it.

On the other side of the coin significant damage could require a complete reconstruction of the wall, which could include walls studs and fiberglass insulation.

Drywall that has been damaged by water often contains mold spores that cannot be removed easily. In the majority of cases the drywall will need to be replaced. We employ moisture testing instruments to measure the amount of the moisture. This helps us identify damaged areas and limit the costs to areas that need to be repaired.

Water can also cause structural damage, as it causes the material to expand or contract. It is easier to break wood if it has been moistened with water. If the water sits for a long period of time, it could cause an abundance of rot in the wood which can cause it to crack easily.


This problem can be avoided by building owners and homeowners immediately taking action to repair structural damage from moisture-related issues that affect their property after flooding or other water-related damage.

Foundation Water Damage

Damage to a home’s foundation can happen due to various reasons. While not all water concerns result in structural damage, it’s essential to fix foundational issues promptly to avoid structural damage.

Water damage to the foundation can lead to many different problems based on how it’s dealt with. If the damage is not treated promptly, it could result in serious structural damages.


Roof Water Damage

Water damage to roofs can result from natural disasters as well as foundation water damage. Roof damage can lead to roof leaks, and can also cause damage to the foundation of a structure or home.

Leaking roofs are extremely costly and can have significant negatives. Roof leaks can lead to mold growth and can be fatal. A leaky roof can affect the roof truss structure that can lead to structural damage to the roof.

Leaks in the ceiling can cause your rafters’ to degrade and become soft if you don’t address them immediately. Electrical faults are also prevalent in the case of roof water damage that can lead to the possibility of an electrical fire. These are all good reasons to get roof water damage repaired swiftly following a flood or other unexpected damage.

HVAC Water Damage

If your HVAC system starts to fail or brand new equipment is found to be defective, it could cause the structure of your home. You are putting your home and business at risk in the absence of HVAC. It can lead to serious health issues.

Damage to Pipes from Water

If you’re suffering from pipe damage due to water, it will likely be coming from a ruptured pipe inside your home. When you’ve discovered that there is leak, it’s crucial for you to contact a professional to stop the leak and ensure that it doesn’t cause structural damage.

A burst pipe can cause devastating damage. When your pipes break they can let water into your home, causing severe damage and requiring repair of water damage. This is an event that could result in structural damage.

As soon as you notice broken pipe water damage stop the supply of water.

What’s the price to repair the water damage?

Water damage restoration cost per square foot

Depending on the square foot, water damage repairs and cleanup expenses can vary. The following breakdown of pricing can be obtained at National Flood Services for each square foot

Are water damage covered By Homeowner’s Insurance?

Insurance policies for homeowners are typically appropriate if the damage is sudden and not intentional. The Insurance Information Institute states that homeowners insurance may cover the repair or replacement of broken windows but not for damages caused by neglect.

Neglect is defined as damage to an object or surface 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 caused by negligence.

A homeowner’s insurance policy will not be able to cover damage to water caused by flooding. Flood insurance is mandatory. In some areas the flood policies are demanded by mortgage lenders. Flooding can be caused by floods, storms and overflowing bodies or the overflowing or surge of bodies like streams, rivers, lakes and oceans.
