Water damage remediation – Tamalpais Valley Junction

Homeowners in Tamalpais Valley Junction get hit with flood damage on a regular basis. Whether you’ve been affected by a natural disaster or a localized catastrophe such as a water line breakage, Critical Control is standing by to respond 24/7.

Water damage is more common when water gets into a structure or residence by way of a flood, storm or ruptured pipe. Sometimes, the damage is obvious and apparent. In other instances, it’s more subtle or unreported.

It’s more complex than just drying out the interior to fix water damage. Modern methods for water damage restoration typically restorers such as Critical Control can mitigate damage that would in the past would have required a complete structural replacement, that is to say, in the sense of demolish and rebuild.

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

A lot of times, homeowners or builders attempt to repair water damage with DIY solutions found online. This is inadvisable. Water damage can be controlled according to established guidelines. These guidelines demand 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 associated risks.

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

There are really important reasons why professionals dealing with water damage must follow these guidelines. In some situations there are situations where an Indoor Environmental Professional (IEP) is required. An IEP is an individual who has the expertise and training to evaluate a site for contamination and take samples, conduct lab tests and offer us suggestions on the kind of water damage that is likely to occur.

This is particularly important when the building’s occupants are at high risk or have concerns regarding contamination.

Categories and classes of Water Damage


Restoration projects for water damage are classified according to category and class based on the degree of flooding of water.

The class is based on how dirty the water entering the structure is. The category 1 indicates that the water comes from a clean source such as a burst water supply or even a sink or tub.

Category 2 is water that has significant levels of contaminants, and could be able to cause illness or discomfort when inhaled or consumed. These sources can be water that is not obvious as a danger like the discharge 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 any other harmful substances. It can be caused by backflows of sewage, toilet trap leaks, and the flooding of rivers and streams. This kind of water could contain heavy metals, pesticides that are regulated, toxic materials, or substances within it.


It is also possible to use the IICRC’s courses to determine how much water has entered your property. This is basically setting guidelines for the level of saturation of the structure or the home.

Class 1 means the least amount of water and absorption. This happens when water comes into contact with less than 5% building materials that absorb water. This is due to the fact that most of the materials that are affected by water won’t retain or absorb water. Examples are concrete, finished/coated wood, plaster or masonry.

Class 2 refers to water absorption and intrusion. It is approximately 10% to 40% of the combined ceiling, floor and wall comprised of low-evaporation materials such as plaster, wood, concrete, or masonry.

Class 3 means that about 40% or more of the wall, floor and ceiling surfaces are porous such as carpet, insulation, fiberboard and so on. and other materials that do not 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 become deeply stuck in materials that do not readily absorb water, such as plaster, wood, concrete and the masonry. This will require more time to dry and special drying techniques.

How Drying a Water Damaged home or Building Works


Physical extraction, dehumidification, and evaporation are considered three ways to get rid of water from buildings. Eliminating water from liquids is typically 500 times more effective than using dehumidifiers or air movers. The quicker the structure dries the more efficient. The quantity of material that needs to be extracted will affect both dehumidification and extraction techniques.

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

Forced Evaporation

The remaining moisture is dried by high-speed airmovers after the maximum amount of water is removed.

Submerged objects absorb water and moisture once it’s wet. As a result, the material becomes dampened or wet.

The degree of saturation is described as the point at which it becomes impossible to contain any more moisture. Higher humidity means that the air is getting closer to saturation.

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

In other words, the object will no longer absorb additional moisture from the air. This is referred to as the saturation point. Once saturation is attained the drying process commences.

In the process of evaporation high-efficiency air movers dry the object from two sides. They produce strong airflow that is controlled by a filtering system.

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

The object is dried using air movers approximately 10 times faster than the natural environment where there was no air movement.

The high-speed airflow dry the surface of the object and draws in the moisture that has been drawn out by the air movers.

Utilizing Heat to Aid the Drying Process

One of the most essential elements for any water damage restoration is the use of heat. To dry out materials that have been affected by water, we make use of a number of different types of heaters.

Electric Heaters These heaters are perfect for drying tasks that require the use of multiple heating sources. This is because they come in a variety of power levels, which allows you to use multiple heaters at the same time.

You can also reduce or turn off the electric heater as the work is completed, but without impacting other heaters. This means that you could lower one heater, while increasing the wattage of another to maximize efficiency, and decrease your cost of energy.

Because they emit virtually no emissions and require very less water, electric heaters are very popular in restoration projects. The only downside is that they take longer to get hot, which requires more time for the drying process generally.

Hydronic Bioler (TES): These boilers are extremely efficient at heating up quickly, while still producing very little emissions. They can be run on natural gas or propane.

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

When electric heaters cannot be employed, hydronic boilers may typically be utilized. They are capable of producing radiant heat and can keep your drying space warm without the need for electricity.


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

The LGR Home Dehumidifier can draw 170 pints of water from damp structures that have experienced severe water damage within 24 hours.

The home dehumidifier can extract water from the air in the same manner it does an LGR Refrigerant Dehumidifier. It will also eliminate up to 99 percent of the mold spores that are airborne by eliminating condensation.

Repairing Wood Floor Water Damage

It is important to remove water damaged hardwood floors to allow repairs to be completed from the subflooring up.

Subflooring that is damaged first has to be removed and repaired. Next, the hardwood boards damaged must be sanded or replaced. When the repairs are finished and the floor is finished, it should be sanded, refinished and polished to ensure uniformity.

Carpets are susceptible to water damage

If you have experienced an incident of flooding in your home this can be a stressful and expensive experience. You might need to change your flooring even if you’ve taken the water out of the area as soon as is possible.

After investing time and money in restoring your home to its pre-flooding condition, it will be depressing to discover that the end result leaves something to be desired.

It is vital to identify the severity of the damage as quickly as is possible. The first step is determine if the affected area needs to be replaced. There’s a good chance that the carpet will be maintained and cleaned once it is dry, and this cleaning can help to eliminate the worries about the growth of mildew and lingering odors.

Salvaging Carpet After a Water Damage Event

If the damage from water is very extensive, it is possible that you’ll see noticeable stains on your carpeting. Sometimes, you will have to replace your flooring to get rid of the stain. A strong, lingering odor can also be an indication to change your carpet. It is necessary to replace your padding and carpet when this happens.

Check to see if the flooring can be dried professionally before deciding whether you want to change it. If you have a reputable company perform the cleaning, then you will have a better understanding of how severe the water damage was. We will be able to determine if your carpet needs to be replaced or can be salvaged. Keep in mind that certain methods employed to dry the carpet can further damage the carpet when it is already in poor condition.

Some of the considerations that will determine whether or whether the padding and carpet need to be replaced are:

Do your carpets get professionally dried, cleaned, and disinfected?

If the padding underneath your carpet has been damaged, it could affect the time that your carpet is clean. Although your carpet might have been dried immediately however the risk of mildew growth is still present if the padding under it has not dried as well.

The safest way to ensure that your carpet is cleaned and disinfected following flooding is to employ a professional carpet cleaning company. Once the company has completed their task, you’ll be able to make a more informed decision about the condition of your carpet and determine whether or not you need to change it.

Drywall damaged by water

The procedure for repair of drywall differs based on the extent of damage. Water damage repair can be as simple as removing a section of drywall cleaning it, after that, replacing it.

The flip side of the coin is that significant damage may require a complete replacement of the wall, which includes the wall studs and fiberglass insulation.

Mold spores can be found in water damaged drywall that is difficult to remove. So in most cases the drywall needs to be replaced. We use moisture testing tools to measure the amount of the moisture. This allows us to identify damaged areas and limit the cost to those areas that are only damaged.

Water can cause structural damage as well, as it causes the material to expand or shrink. After the wood has been moistened with water, it’s much more difficult to break. The wood may get brittle if allowed to dry in water for too long.


This issue can be prevented by owners of buildings and homeowners taking immediate action to fix the structural damage caused by moisture-related problems with their property following flooding or other water-related damage.

Water Damage to the Foundation

There are numerous reasons why water damage could affect a foundation of a house. While not all water concerns result in structural damage, it is essential to fix foundational issues as quickly as possible to prevent structural damage.

Foundation water damage can cause many different problems in the manner it is handled. It can cause severe structural damage if it isn’t taken care of promptly.


Roof Water Damage

As with foundation water damage roof water damage is also quite common following natural catastrophes. Roof damage could cause roof leaks and also damage the foundations of a structure or home.

Roof leaks can be costly and may have significant drawbacks. Leaks in the roof may result in mold and mildew to grow, which can cause death. The leaks in the roof could cause damage to the roof truss system.

If you don’t address the leaks in your ceiling promptly, they can cause your rafters to degrade and become soft. Water damage to the roof could result from electrical issues that can cause an electrical fire. There are many reasons to have your roof water damage taken care of promptly following a flood or other type of unexpected damage.

HVAC Water Damage

If your HVAC system begins to fail or brand new equipment becomes defective, it could result in the structure of your home. If you do not have HVAC it is exposing the inside of your house or business to all kinds of problems. The growth of mold can lead to a number of health issues that are very serious.

Damage to the Pipe Water

If you’re suffering from pipe water damage, the water is most likely coming from a pipe that has burst in your home. If you’ve discovered a leak, it is crucial to get an expert to stop the water from creating structural damage.

Burst pipes can cause a number of damages. When pipes are damaged and water enters your home, causing extensive damage , and may require repair of water damage. This is which can bring with it structural damages.

If you spot water damage to your pipe that is not repaired stop the supply of water.

What’s the price to fix the damage caused by water?

Water damage restoration cost per square foot

Based on the square foot the water damage repairs and cleanup expenses vary. National Flood Services has the following breakdown of pricing for each square foot:

Are water damages covered by homeowners’ insurance?

Homeowners insurance policies are usually applicable if the source of the damage is sudden and not intentional. The Insurance Information Institute states that homeowners insurance can provide for the repair or replacement of broken windows but not for damages caused by neglect.

Neglect can be described as damage to an object or surface that is the result of exposure, poor maintenance or general wear and tear. According to the Insurance Information Institute, a US-based Insurance Information Institute, homeowners insurance doesn’t cover damage caused by negligence.

If the water damage resulted from an event that is a flood, it is not covered under the homeowners insurance. A flood policy is required. Mortgage lenders might need flood insurance in specific regions. Flooding can occur due to storms, flooding ground and overflowing bodies or the overflowing or surge of bodies like streams, lakes, rivers and oceans.
