Flooding damage repair – Corte Madera

Building owners in Corte Madera suffer burst pipe damage regularly. Whether you’ve suffered from a natural disaster or a localized catastrophe such as a fire suppression activation, Critical Control is standing by to respond 24/7.

When a flood, storm, or burst pipe causes water to enter a house or building, water damage occurs more often than not. Sometimes the damage is apparent and evident. Sometimes, the damage is hidden or not reported.

The process of repairing water damage is more complicated than just drying the interior. Modern professional techniques for water damage repair such as Critical Control, can often mitigate damage that would otherwise require a complete structural replacement.

Water Damage Restoration Guidelines are readily available Contact a Professional

A lot of times, property or home owners attempt to deal with water damage using DIY solutions found online. This is not a good idea. The management of water damage is according to established guidelines. These guidelines demand the expertise and equipment of experts. The guidelines can be found in the IICRC Standard Reference Guide, or Professional Water Damage Restoration book. This guide is required to ensure the professional standardisation of instances involving water damage to houses or buildings, and the risks associated with it.

Critical Control, a restoration firm, is able to use IICRC guidelines to help them evaluate the severity and nature of each project’s damage.

There are a lot of reasons why professionals dealing with water damage should adhere to these guidelines. There are situations that warrant the use of the services of an Indoor Environmental Professional (IEP). An IEP is an expert who has the experience and knowledge to examine the condition of a place take samples, perform laboratory tests, and help us determine the kind of water damage.

This is particularly important in situations where the occupants of the building could be high risk, there is a likelihood of adverse health effects, the people who live there have a desire to know the contaminants that are suspected or have another reason to raise concerned about contamination.

Categories and Classes of Water Damage


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

The water that entered the structure was classified according to its contamination. The category 1 indicates that the water comes from a clean source, such as burst water supply, or tub or sink.

The category 2 water contains significant amounts of contaminants and is likely to cause illness or discomfort if contacted or consumed. These include sources that may not normally seem like a threat such as discharges from washing machines, or overflows from toilets.

Water in Category 3 can be considered to be extremely contaminated. It could be contaminated by toxic, pathogenic, or any other dangerous substances. This usually means contamination from toilet backflows following the trap for toilets or a flood of seawater from rivers and streams, or any other source of water that comes from the exterior of the building. This water can include heavy metals, pesticides or toxic substances.


The IICRC has also established classes that we follow in determining the degree of water intrusion to your property. This system is basically a guideline for how much saturated a structure or home is.

Class 1 means the least amount of water and absorption. It is the case when water comes in contact with around 5% or less with construction materials that absorb water. This is typically the case that the majority of the building materials affected by water are low evaporation. This means they don’t soak up and retain water. Examples include concrete, coated or finished wood, plaster or masonry.

Class 2 signifies that there is a significant absorption of water and intrusion. It’s about 5 up to 40% of combined ceiling, floor and wall consist of low evaporation materials such as plaster, wood, concrete, or bricks and mortar.

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

The water has been absorbed into materials such as concrete, plaster, and wood that are classified as Class 4. This is why special drying methods are required and longer drying time.

How Drying a Water Damaged Building or Home Building Works


Three ways to remove water from buildings are physical extraction, dehumidification, and evaporation. Removal of liquid water is at least 500 times more effective than simply putting up with dehumidifiers and air moving machines. The quicker 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 professionals use an array of extraction techniques. We have wands, subsurface extraction tools as well as self-propelled tools and vacuum squeezers.

Forced Evaporation

The remainder of the moisture gets dried with high-velocity air movers after as much water as possible has been removed.

Submerged objects absorb water and moisture once it’s wet. The material gets wet or damp because of this.

Saturation is the time where it becomes unachievable for the air to contain any moisture. The higher the humidity, the more close the air is to being saturated.

The evaporation phase is the time when water molecules transition from an in liquid state to a gaseous one. The process is called evaporation.

In this way the object does not absorb any more moisture from the atmosphere. We call that saturation point the point of evaporation. As soon as saturation is reached the drying process starts.

High-efficiency air movers dry objects in two areas in the evaporation phase. They create strong airflow which is directed by a filter system.

An air mover moves around 10 to 20 times the amount of air than a fan , or an ordinary fan.

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

Airflows that are high-velocity dry the surface and absorbs the water that is drawn out by air movement.

Use heat to assist the drying process

One of the most essential elements for any water damage restoration project is the use of heat. In order to dry out any materials that have been affected by water, we make use of various types of heaters.

Electric Heaters They are ideal for drying tasks that require several different heat sources. You can run multiple heaters simultaneously due to their numerous wattages.

You can also reduce or off electric heat as the work is done, without affecting other heaters. This means that you could reduce one heater while increasing the power of another to maximize efficiency, and decrease your energy costs.

Because they emit almost no carbon dioxide and require less water They are popular for restoration projects. They take longer to warm up and need more time to dry.

Hydronic Bioler (TES) Hydronic Bioler (TES) These boilers are able to heat quickly and emit very little emissions. They typically operate on natural gas or propane.

Hydronic boilers differ from electric heating in that they do not utilize forced-air for distribution of heat, which means it could be challenging to evenly heat an space with these kinds of heaters. They also operate at a lower temperature, making ideal for drying projects that require walls and ceilings to remain in place.

Hydronic boilers are often used when there is no electricity to run electric heaters. They can produce radiant heat, and they can keep your drying space warm without the requirement of an electric source.


To dry buildings and houses that are damaged due to flooding, we use Low Grain Refrigerant (LGR) Dehumidifiers.

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

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

Fixing Hardwood Floor Water Damage

The floors that have been damaged by water need to be removed so that repairs can be made beginning with the subflooring and moving upwards.

The subflooring has to be taken off and repaired before. The affected hardwood floors require sanding down or replaced. In order to ensure a uniform appearance the floors must be sanded, then repaired after these repairs are completed.

Water Damage to Carpeting

If you have been unfortunate enough to have a flood in your home, it can be a costly and stressful experience. Even if the water is removed from the affected area immediately, there is an opportunity that you will have to eventually replace the flooring.

It would be devastating to find out that your home isn’t in the best condition after spending so much time and money to fix it.

This is why it is important to assess the extent of damage as quickly as is possible. First thing to do is determine if the affected area needs to be replaced. It is possible to clean the carpet and then use it again after drying. This can alleviate any worries about the growth of mildew or lingering smells.

Salvaging Carpet After a Water Damage Event

If the water damage is very extensive there is a chance that you’ll see noticeable staining on your carpet. In certain instances the only option to remove the stains is to replace the flooring. Another factor that could cause you to think about replacing your carpet is the persistent and strong odor. If this is the case then you may require replacement of both your padding and carpet.

The next step in determining whether or not you need to replace your carpet is to determine if the floor can be cleaned and dried professionally. If you have a reputable company perform the cleaning, then you will have a better understanding of how severe the water damage was. We can assess whether your carpet needs to be replaced or can be saved. If the carpet you have is damaged, certain drying techniques can further damage it.

A variety of factors can determine the decision of whether padding or carpet need to be replaced.

Can your carpets be dried or cleaned professionally?

If the padding under your carpet is damaged, it can impact how long the carpet is clean. Although your carpet might be dry however the risk of mold growth is present if the padding under isn’t dried too.

A professional carpet cleaning service is the best option to ensure your carpet is dry and clean following an event of flooding. After the company completes their task, you’ll be able to make a more informed decision about the state of your carpet and decide whether or not you need to replace it.

Drywall that has been damaged by water

The process for repairing drywall varies based on the extent of the damage. Repairing water damage can be as simple as removing a portion of drywall, cleaning the area, and then putting it back.

The other side is that major damage could require whole-wall replacement including walls studs and fiberglass insulation.

Water damaged drywall often harbors mold spores that cannot be removed easily. So in most cases, drywall will need to be replaced. We employ moisture testing instruments to assess the extent of moisture. This allows us to isolate areas of damage and limit costs to only necessary damaged areas.

Water can also cause structural damage as it causes the material to expand or expand or contract. It is much more difficult to break wood if it has been moistened with water. If the water is left to sit for a prolonged time, there could be an abundance of rot on the wood, which could cause it to break easily.


This issue can be prevented by homeowners and building owners taking immediate action to fix the structural damage caused by moisture-related issues with their property after an event like a flood or water-related damage.

Foundation Water Damage

There are a variety of reasons that water damage can cause to a foundation of a house. Although not all water problems cause structural damage, it is important to correct foundational issues as soon as possible in order to avoid any future structural damage.

The damage caused by water in the foundation could cause a number of different issues dependent on the way it is handled. It can lead to serious structural damage if not taken care of quickly.


Roof Water Damage

Damage to the roof can be caused by natural catastrophes, just like foundation water damage. Roof damage could cause roof leaks, and can also cause damage to the foundations of a building or house.

Leaking roofs are extremely expensive and could have major disadvantages. Leakage in the roof could result in the growth of mold, which can prove fatal. A leaky roof can harm the roof truss system and cause structural damage to the roof.

If you don’t fix leaks in your ceiling right away they could cause the rafters to decay and then soften. Electrical problems are also common when it comes to roof water damage which can cause the possibility of an electrical fire. These are all good reasons to have your roof water damage repaired quickly following a flood or other unexpected damage.

HVAC Water Damage

If your HVAC system begins to fail or brand-new equipment becomes faulty, this can definitely result in the structure of your house. If you do not have HVAC you’re exposing the inside of your house or business to all kinds of problems. It is possible for mold to grow and result in a range of serious health issues.

Damage to the Pipe Water

If you’re experiencing pipe water damage, it will likely be coming from a burst pipe in your home. Once you’ve determined there’s leak, it’s important to call an expert to prevent the water from causing structural damage.

A ruptured pipe can result in devastating damage. The water could enter your home through broken pipes, which can cause severe damage. This can lead to structural damage.

Shut off the water supply, and then contact an experienced IICRC-certified professional at a water restoration firm like Critical Control as soon as you detect broken pipe water damage.

What is the cost to repair water damage?

Water damage restoration cost per square foot

Based on the square feet the repair and cleanup costs can vary. The following breakdown of pricing is available at National Flood Services for each square foot

Does water damage get insured by the homeowner’s insurance?

Homeowners insurance policies are usually used if the damage is sudden and unintentional. The Insurance Information Institute states that homeowners insurance may be used to pay for repairs or replacement of broken windows but not for damages caused by negligence.

Neglect is defined as damage to an object or surface that results from the weather, lack of maintenance or general degradation. According to the US-based Insurance Information Institute, homeowners insurance will not cover damages from neglect.

A homeowners policy would not be able to cover damage to water due to flooding. A flood policy is required. In some areas, flood policies are required by mortgage lenders. Flooding can be caused by floods, storms or overflowing bodies of water, or overflowing or surging bodies like streams, rivers, lakes and oceans.
