Flooding damage repair – Walnut Creek

Building owners in Walnut Creek suffer flood damage on a regular basis. Whether you’ve experienced 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 enters a building or residence via a flood, storm or burst pipes. Sometimes the damage is overt and obvious, sometimes it is minor or hidden.

It’s more difficult than just drying out the interior to repair water damage. Modern methods for water damage remediation such as Critical Control, can often reduce damage that would normally require a complete structural replacement.

Water Damage Restoration Guidelines are in place – So Call a Professional

Many times, homeowners or builders try to fix water damage using DIY solutions that can be discovered on the internet. This is a bad idea. There are guidelines to deal with water damage , and they depend on the tools and skills of experts. The guidelines are set forth in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide is created because of the need for professional standardisation in situations involving water damage to homes and buildings and the dangers they can create.

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

These guidelines are essential for professionals who deal with water damage. In certain circumstances there are situations where the use of an Indoor Environmental Professional (IEP) is required. An IEP is a professional who has the training to assess the health of a building and collect samples, conduct laboratory tests, and advise us on the category of water damage.

This is crucial when the building’s occupants might be at risk, there are a chance of adverse health consequences, or the occupants are required to determine the contaminants that are suspected, or some other reason to raise concerned about contamination.

Water damage through types and classes


Restoration of water damage projects are classified according to category and class depending mostly on the severity of the flood.

The classification has to do with how contaminated the water that enters the structure is. Category 1 is water that is clean like the sink or tub, or a water source that bursts.

Category 2 involves water that has significant levels of contaminants, and could be able to cause illness or discomfort when inhaled or consumed. It could include sources that are not usually considered to be dangers, such as the discharge from washing machines or overflows from toilets.

The water in Category 3 is highly polluted, meaning it could contain pathogenic, toxic or any other harmful agent in it. Usually this means contamination by sewage, toilet backflows after the toilet trap or a flood of seawater from streams and rivers, or any other water flowing from the exterior of the building. This water can include heavy metals, pesticides or harmful substances.


The IICRC has also developed classes that we follow in determining the degree of water intrusion on your property. This is basically setting guidelines for the saturation of the building or home.

The lowest level of water absorption , and the most water is classified as Class 1. This is when water is in contact with less than 5% construction substances which absorb water. This is because most substances that are affected by water do not hold or absorb water. Concrete or plaster, masonry and coated or finished wood are only several examples.

Class 2 means that there is a significant infiltration of water as well as intrusion. This means that between 5 and 40% of the total ceiling, floor and wall is made of materials with low-evaporation, such as wood, concrete, or bricks and mortar.

The porous materials, such as carpet, insulation and fiberboard, that make up Class 3 comprise around 40 percent of the floor, wall and ceiling materials, including around 40% in class 3. and where other materials that do not absorb water like plaster or concrete have not been adversely affected.

Water has been absorbed by substances like concrete or plaster and wood, which are classified as Class 4. This is why special drying methods are required and longer drying time.

How do you dry a water damaged Building or House


Physical extraction, dehumidification and evaporation are three ways to get rid of water from a structure. Eliminating water from liquids is typically 500 times more efficient than using dehumidifiers or airmovers. The faster the structure can dry, the better. Both methods of extraction and dehumidification will be affected by how much of the material is extracted.

Water damage professionals employ a variety of extraction techniques. We make use of a variety of equipment, such as subsurface extraction tools as well as self-propelled tools.

Forced Evaporation

The remainder of the moisture gets dried using high-speed air movers once as much water as possible has been taken away.

Submerged objects absorb water and moisture when it’s moistened. In the process, the material gets dampened or wet.

The level of saturation is referred to as the point at which it is impossible to hold any additional moisture. The greater the humidity, the more close the air is getting to saturation.

In the evaporation process in which water molecules are ejected from liquid state to gaseous state. This is known as the process of evaporation.

In this way the object does not absorb any more water from the atmosphere. This is called the saturation point. Once saturation is reached, drying will begin.

In the evaporation stage, highly-efficient air movers dry the object from two sides. They create strong airflow which is controlled by a filter system.

An air mover can move around 10 to 20 percent more air than an ordinary fan, or an ordinary fan used in the home.

Air movers dry objects about 10 times more quickly than natural conditions, where there isn’t any air mover.

A high-velocity airflow is able to dry the surface of the object and absorbs the water that was pulled away by the air movement.

Use heat to assist the drying process.

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

Electric Heating Equipment: These heaters can be used to dry jobs that require multiple heating sources. You can run multiple heaters simultaneously due to their numerous wattages.

It is also possible to turn off or turn off the electric heater while the job is being done, without affecting other heaters. This means you can reduce one heater while raising the wattage of another one to improve efficiency, and decrease your expenses for energy.

Since they produce virtually no emissions and require very less water They are popular for restoration projects. They take longer to warm up and need more time to dry.

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

Hydronic boilers are different from electric heat in that they do not use forced-air to distribute heat, which means it could be challenging to evenly heat a large area with these types of heaters. They can also be used for dry work that does not require walls or ceilings to be able to stand in the same place.

They are also commonly used when there is no power available to run electric heaters. Because they are extremely efficient in producing radiant heat, they can easily keep your drying area warm even when there is no electric power source.


We employ Low Grain Refrigerant Dehumidifiers (LGR) to help dry out buildings as well as houses that have suffered water damage.

The LGR Home Dehumidifier is capable of extracting 170 pints of water in an un-dry structure that has been severely affected by water damage every 24 hours.

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

Repairing Wood Floor Water Damage

Hardwood floors damaged by water have to be ripped up so repairs can occur starting from the subflooring up.

The damaged subflooring first needs to be removed and repaired. The affected hardwood floors must be sanded or replaced. In order to ensure a uniform appearance the floors must be sanded down and refinished after these repairs have been made.

Water Damage To Carpeting

Floods can cause significant damages to your house and cause it to be expensive and time-consuming. You might need to change your flooring, even if you have eliminated the water from the area as fast as is possible.

After spending time and money restoring your home to its pre-flood condition, it would be depressing to discover that the end result leaves an unsatisfactory impression.

This is why it is crucial to determine the extent of the damage as soon as possible. First thing to do is to determine if the damaged area requires replacement. It is possible to wash the carpet and use it after drying. This can alleviate any worries about mildew growth or persistent scents.

Salvaging Carpet After a Water Damage Event

You may notice stains on your carpet if the damage to your carpet was severe. Sometimes, you will have to change your flooring to remove the stain. A persistent, strong odor may also be the reason to replace your carpeting. If it is it is likely that you’ll need to replace both the padding and carpet.

Next, determine if your flooring can be dried professionally before deciding whether you want to replace it. Professionals can aid you in determining the severity of the damages were. Our team will evaluate the carpet and decide whether it is best to replace it or salvageable. If your carpet is damaged, certain drying methods could further harm it.

A few of the factors that determine whether or whether the padding and carpet require replacement are:

Are your carpets dry or cleaned professionally?

The carpet’s ability to remain clean is affected when the padding beneath it has been damaged. Even though your carpet is dried fast, the growth of mildew can still occur when the padding beneath isn’t dried.

The safest way to ensure that your carpet is restored and disinfected after an event of flooding is to engage a professional carpet cleaning company. Once the cleaning is complete you’ll be able to take a shrewd decision on the state of your carpeting. It is also possible to decide whether you want to replace it.

Drywall damaged by water

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

The opposite of this is that significant damage may need to be repaired completely, including walls studs and fiberglass insulation.

Water damaged drywall often harbors mold spores which can not be easily removed. In most cases, the drywall will have to be replaced. We utilize moisture testing tools to assess the extent of the moisture. This allows us to pinpoint areas that are damaged and limit costs to only the areas that are damaged.

It also causes structural damage by causing the wood material to expand and expand and contract. When the wood is saturated with water, it’s a lot easier to break. The wood may be brittle if allowed to dry in water for too long.


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

Foundation Water Damage

There are numerous reasons why water damage could affect the foundation of a home. Although not all water problems cause structural damage, it’s important to address foundation issues as soon as possible to avoid further structural damage.

The damage caused by water in the foundation could cause many different problems depending on how it is handled. It can cause severe structural damage if the issue isn’t treated promptly.


Roof Water Damage

As with foundation water damage roof water damage is quite common following natural catastrophes. Along with the possibility of roof leaks, roof damage can also result in problems with the walls and foundations of a the building.

Leaking roofs are extremely costly and can have significant drawbacks. Leaks in the roof can cause mildew and mold to grow, which can be deadly. Leakage in the roof can also cause damages to the roof truss.

Leaks in the ceiling can cause your rafters to deteriorate and soften if you do not deal with them right away. Electrical faults are also prevalent in the case of roof water damage which can cause the possibility of an electrical fire. All of these are good reasons to have your roof water damage repaired swiftly following a flood , or any other sudden damage.

HVAC Water Damage

If your HVAC system starts to fail or brand-new equipment is found to be faulty, this can definitely result in the structure of your home. Your home and business at risk by not having HVAC. The growth of mold can cause serious health problems.

Pipe Water Damage

If you’re suffering from pipe water damage, it will likely be coming from a ruptured pipe inside your home. When you’ve identified leak, it’s crucial to get an expert to stop the water from damaging the structure.

A burst pipe can cause serious damage. When pipes are damaged they can let water into your home, causing extensive damages and necessitating water damage repair – an event that could result in structural damage.

Shut off the water supply and call an expert IICRC-certified specialist from a company for water restoration such as 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 water damage repair and cleanup costs can vary. National Flood Services has the following pricing breakdown per square foot.

Is water damage insured by the homeowner’s insurance?

Insurance policies for homeowners are typically applicable if the source of the damage is sudden and not intentional. According to the Insurance Information Institute, homeowners insurance policies can cover repair or replacement for a damaged window, but not if the damage occurs as a result of neglect.

Neglect is defined as damage to an object or surface that is the result of the weather, lack of maintenance or general wear and tear. According to the US-based Insurance Information Institute, homeowners insurance will not cover damages caused by negligence.

If the water damage resulted from a flood, the event is not covered under homeowner’s insurance. Rather, a flood policy is required. In some areas, flood policies are required by mortgage lenders. Flooding can occur due to storms, flooding ground, overflowing bodies of water or overflowing or surging bodies like streams, rivers, lakes and oceans.
