Flooding damage repair – Mill Valley

Property owners in Mill Valley get hit with water damage on a regular basis. Whether you’ve experienced a natural disaster or a localized catastrophe such as a ruptured pipe, Critical Control is standing by to respond 24/7.

Damage to water is more frequent when water seeps into a building or residence through a storm, flood or burst pipes. Sometimes the damage is visible and obvious, sometimes it’s hidden or minor.

The process of repairing water damage is more complicated than just drying the interior. With modern professional methods for water damage restoration, often restorers like Critical Control can mitigate damage which, in the past, would have required complete structural replacement, that is to say, in other words, demolish and rebuild.

Water Damage Restoration Guidelines Are In Place and you can call a Professional

A lot of times, homeowners or builders attempt to repair water damage by using DIY solutions that can be discovered on the internet. This is a mistake. Water damage can be controlled in accordance with established guidelines. These guidelines demand the skills and tools of experts. These guidelines are detailed in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide is necessary to ensure professional standardisation of situations involving water damage to buildings or homes, and the risk associated with it.

The IICRC guidelines assist restoration professionals like Critical Control to evaluate the kind and severity of the damage on each project.

There are really important reasons why water damage experts should follow these guidelines. In certain circumstances it is necessary to employ an Indoor Environmental Professional (IEP) is necessary. An IEP is an expert who has the experience and knowledge to examine the condition of a place and collect samples, conduct lab testsand advise us on the category of water damage.

This is particularly important in cases where the building’s occupants are at risk or are concerned regarding contamination.

Water destruction caused according to types and classes


Restoration projects for water damage are classified into two categories, depending on how extensive the infiltration of water is.

The water entering the building was classified according to its level of contamination. Category 1 water originates from a clean source, such as the 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 when inhaled or consumed. These sources can be waters that are not readily apparent as a risk like the discharge from washing machines and overflows from toilets.

Water in the category 3 is severely contaminated meaning that it can have pathogenic, toxigenic or other harmful substances within it. It can be caused by backflows of sewage, leaks in toilet traps, and floods of water from rivers and streams. This kind of water could include heavy metals, pesticides, regulated materials or toxic substances within it.


The IICRC has also developed classes that we follow in determining the degree of water intrusion to your property. This system is basically an outline of how saturated a building or home is.

The lowest level of absorption by water and the highest amount of water is classified as Class 1. This is when water is in contact with less than 5% of construction substances that absorb water. This is usually the case where most of the substances affected by water have low evaporation, meaning, they don’t soak up and retain water. Concrete, finished/coated wood, plaster or masonry.

Class 2 means that there is substantial absorption of water and intrusion. This means that between 5% and 40% of the combined ceiling, floor and wall is constructed from low-evaporation substances like wood, concrete, plaster, or masonry.

Class 3 is the term used to describe 40% or more of the floor, wall and ceiling materials are porous such as carpet, insulation, fiberboard, etc. and other materials that do not take in a lot of water, such as concrete or cement have not been negatively affected.

Water has been absorbed by materials such as concrete as well as wood, plaster, and even wood, which are classified as Class 4. This is why special drying methods are required and longer drying times.

How do you dry a water damaged building or house


Physical extraction, dehumidification, and evaporation are the three main methods of removing water from buildings. Eliminating water from liquids is at most 500 times more effective than using dehumidifiers or airmovers. The faster the structure dries more efficiently. The amount of stuff to be extracted will influence both extraction and dehumidification techniques.

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

Forced Evaporation

Once all water has been removed, any moisture remaining is then dried by high-speed airmovers.

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

Saturation is defined as the point at which it becomes impractical for the air to contain any moisture. The higher the humidity, the closer the air is to being saturated.

The evaporation phase is the time when water molecules transition from the state of liquid to a gaseous form. This is called evaporation.

In other words the object does not absorb any more moisture from the atmosphere. This is called the saturation point. Once the saturation point is reached drying will begin.

High-efficiency airmovers dry the object on two sides in the evaporation phase. They generate a large airflow across the entire surface that is controlled by a filter that completely covers the surface of the object.

Air mover is able to move between 10 and 20 percent more air than an ordinary fan, or a standard fan in your home.

The object is dried using airmovers about 10 times faster that in natural conditions in which no air mover was employed.

A high-velocity airflow is able to dry the surface of the object and sucks up the water that was taken away by the air mover.

Use heat to assist the drying process.

A key component in any water damage restoration work is heating. We use a variety of heaters to dry the materials that are damaged by water.

Electric Heaters They are ideal for drying jobs which require the use of multiple heat sources. It is possible to run several heaters simultaneously because of their many Wattages.

You can also turn down or turn off the electric heater while the job is being completed, but without impacting other heaters. In order to maximize efficiency and lower the cost of energy you can alter the wattage of one heater and increase its capacity.

Electric heaters are a common feature in restoration jobs because they produce essentially no emissions and use very little water. They require longer to heat up and require more time for drying.

Hydronic Bioler (TES): They are also extremely efficient at quickly heating up and generating very little emissions. They typically operate using propane or natural gas.

Hydronic boilers are different from electric heating since they don’t utilize forced air heat to spread heat. This can make it difficult to evenly heat large areas by using these heaters. They also run at less temperature, which makes ideal for drying projects that require ceilings and walls to be left in place.

If electric heaters are not employed, hydronic boilers may frequently be employed. They can produce radiant heat and keep your drying space warm without the need for an electric source.


We employ Low Grain Refrigerant Dehumidifiers (LGR) to help dry out buildings and homes that have experienced water damage.

The LGR Home Dehumidifier is capable of extracting 170 pints of water from a damp building that is severely damaged by water damage each all day, every hour of the day.

Apart from removing water out of the air like an LGR Refrigerant Dehumidifier does, the home dehumidifier will also eliminate up to 99percent of airborne mold spores the air by eliminating condensation.

Fixing Hardwood Floor Water Damage

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

First, damaged subflooring needs to be taken off and fixed. Then the affected hardwood boards require sanding down or replaced. To ensure a uniform appearance the floors must be sanded down and refinished after these repairs are completed.

Carpets are prone to water damage

If you have been unfortunate enough to have an incident of flooding in your home this can be a stressful and expensive experience. It is possible that you will need to replace your flooring, even if you have removed the water from the area as quickly as is possible.

After spending time and money to restore your home to its original state, it could be devastating to find that the final results leave something to be desired.

It is crucial to determine the extent of the damage as fast as is possible. The first thing to do is to determine if the damaged area needs to be replaced. It is possible to clean the carpet and then use it after drying. This can eliminate worries about the growth of mildew or lingering scents.

Salvaging Carpet After a Water Damage Event

There could be staining on your carpet if the water damage was very serious. In some cases, you may need to replace your flooring in order to get rid of the stains. Another aspect that may prompt you to think of replacing your carpeting is a strong and lingering odor. If you find this to be the case then you may require replacement of both your padding and carpet.

The next step in determining whether or not it is necessary to replace your carpet is to find out whether your floor can be dried and cleaned professionally. A professional company will be able to help you determine how serious the damage was. Our firm will examine your carpet and determine whether it is best to replace it or salvageable. If the carpet you have is in poor shape, some drying methods can cause further damage to it.

Some of the considerations that will determine whether or not the carpet and padding should be replaced include:

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

If the padding under your carpet is also damaged, it can impact the length of time your carpet is clean. Even though your carpet is dried in a short time, mildew growth may still be present in the padding beneath if it is not dried.

The most secure way to make sure that your carpet is restored and disinfected after a flood is to hire a professional carpet cleaning company. Once the company has completed their job, you’ll be able to make a more informed decision about the state of your carpeting and decide whether or not to change it.

Drywall Damaged by Water

The process for repairing drywall varies according to the extent of damage. Repairing water damage can be as simple as removing the drywall portion, cleaning the area, and then replacing it.

On the other side of the coin serious damages could necessitate a total wall replacement, including wall studs and fiberglass insulation.

The drywall that is damaged by water usually harbors mold spores that can’t be removed easily. So in most cases the drywall needs to be replaced. We employ moisture testing tools that help us determine how large and where the water has grown. This allows us to identify damaged areas and limit costs to only necessary damaged areas.

It also causes structural damage because it causes the wood material to expand and contract. After the wood has been moistened by water, it becomes much more difficult to break. If the water remains for a lengthy time, there can be an abundance of rot in the wood which can make it break easily.


This problem can be avoided by owners of buildings and homeowners immediately taking action to repair water-related structural problems with their property following an event like a flood or water-related damage.

Foundation Water Damage

Water damage to a house’s foundation can occur for many reasons. While not all water issues can lead to structural damage, it’s crucial to correct foundational issues as soon as possible in order to avoid any further structural damage.

Foundation water damage can cause various issues dependent on the way it is addressed. If the problem isn’t addressed promptly, it could result in structural damage that is severe.


Roof Water Damage

As with foundation water damage roof water damage is quite common following natural catastrophes. Along with causing roof leaks, roof damage can also cause problems with the walls or the foundation of a house or building.

Roof leaks can be very costly and might have significant disadvantages. Roof leaks can result in the growth of mold, which can prove fatal. A roof that is leaky could affect the roof truss structure, which can cause structural damage to the roof.

Leaks in your ceiling could cause your rafters to deteriorate and become soft if you don’t address them immediately. Electrical problems are also common in the case of roof water damage which could cause an electrical fire. These are all good reasons to have roof water damage repaired immediately following a flood, or any other unexpected damage.

HVAC Water Damage

Your home could suffer structural damage if your HVAC system is not working properly or the wrong equipment is put in place. You are putting your home and business at risk because you do not have HVAC. The growth of mold can cause serious health problems.

Pipe water damage

Pipe water damage is usually caused due to a pipe burst within your home. When you’ve identified an issue, it’s important to call an expert to prevent the water from causing structural damage.

A pipe that bursts can cause serious damage. The water could enter your home through damaged pipes, which can cause severe damage. This could lead to structural damage.

As soon as you notice water damage to your pipe that is not repaired stop the water supply.

What is the cost to fix the water damage?

Will Water Damage Be Covered By Homeowner’s Insurance?

If the cause was sudden and unintentional homeowners insurance policies generally cover it. According to the Insurance Information Institute, homeowners insurance policies can cover repair or replacement for a broken window, but not if the damage occurs as a result of negligence.

Damage from neglect could be described as wear and tear to a surface or object due to exposure, insufficient regular maintenance or general wear and tear. The Insurance Information Institute in the United States states that homeowners insurance does not cover the damage caused by negligence.

A homeowner’s insurance policy will not be able to cover damage to water caused by flooding. Rather, a flood policy would be mandatory. Mortgage lenders may require flood insurance in specific areas. Flooding can happen due to storms, flooding ground, overflowing bodies of water or the overflowing or surge of bodies like streams, lakes, rivers and oceans.
