Flooding damage repair – Oakland

Homeowners in Oakland get hit with flood 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.

Water damage is more common when water enters a building or home via a flood, storm, or burst pipes. Sometimes the damage is apparent and apparent. Other times, it’s subtle or under-reported.

It’s more complex than simply drying the interior to fix water damage. Modern water damage remediation tactics typically restorers such as Critical Control can mitigate damage that previously would have required a complete structural replacement, in other words, demolish and rebuild.

Water Damage Restoration Guidelines Exist and you can call a Professional

Many times, building or home owners attempt to deal with water damage using DIY solutions that can be found online. This is not advisable. Water damage can be controlled according to established guidelines. These guidelines require the skills and tools of professionals. The guidelines are laid out in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide exists because of the need for professional standardisation in situations involving water damage to homes and buildings and the risks they pose.

Critical Control, a restoration firm, is able to use IICRC guidelines to assess the type and extent of each project’s damage.

There are a lot of reasons why professionals dealing with water damage must follow these guidelines. There are situations that warrant us to bring in an Indoor Environmental Professional (IEP). An IEP is someone with the knowledge and experience to analyze an area for contamination, take samples, run lab tests and offer us suggestions on the type of water damage.

This is crucial in situations where the building’s occupants are at risk or are concerned about contamination.

Categories and Classes of Water Damage


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

The class has to do with how polluted the water entering the structure was. Category 1 means 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 has the potential to cause illness or discomfort when inhaled or consumed. These include sources that might not appear to be a threat such as discharge from washing machines or overflows from toilets.

Water in Category 3 can be classified as highly contaminated. It could contain pathogenic, toxic, or other dangerous substances. It can be caused by sewage backflows, toilet trap leaks, and water flooding from rivers and streams. The water in this category could include heavy metals, pesticides and regulated substances as well as toxic substances in it.


The IICRC has also created classes we use in measuring the amount of water intrusion on your property. The system basically serves as an outline of how much saturated a structure or home is.

Class 1 is the smallest amount of absorption and water. This is when the water comes in contact with about 5percent or less of building materials that absorb water. This is because the majority of substances that are affected by water won’t hold or absorb water. Concrete or plaster, masonry and wood that has been finished/coated are some of the examples.

Class 2 indicates that there is significant infiltration of water as well as intrusion. This is about 5 up to 40% of the total floor, wall and ceiling consist of low evaporation materials such as plaster, concrete, wood or the masonry.

Class 3 refers to the fact that around 40 percent or more of flooring, walls, and ceiling surfaces are porous materials like fiberboard, insulation, carpet, etc. and where other materials that do not absorb water like concrete or cement have not been negatively affected.

Class 4 indicates that water has become deeply trapped in the materials that can not readily absorb water, such as plaster, wood, concrete and the masonry. This calls for special drying techniques and longer drying time.

How to Dry a Water Damaged House or Building


Three ways of removing water from buildings include physical extraction, dehumidification and evaporate. The removal of liquid water is at minimum 500 times more efficient than just making do with dehumidifiers and air moving machines. The faster the structure is dried, the better. Both extraction and dehumidification methods will be affected by how much material is being removed.

Water damage experts employ a variety of extraction methods. We have wands, subsurface extraction tools, self-propelled tools, and vacuum squeegees.

Forcible Evaporation

After the water is removed, any moisture remaining is then dried by high-speed airmovers.

A submerged object absorbs moisture and water when it’s moistened. As a result, the material gets dampened or wet.

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

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

This means that the object no longer absorbs water from the atmosphere. The saturation point is the point of evaporation. When saturation is reached, the drying process begins.

In the evaporation stage high-efficiency air moves dry the object on two sides. They produce strong airflow that is controlled by a filtering system.

A fan that moves air can move around 10 to 20% more air than a fan, or an ordinary fan used in the home.

The object is dried by airmovers about 10 times faster than natural conditions where there was no air movement.

A high-velocity airflow dries the surface of the object and absorbs the moisture drawn out by the air movers.

Utilizing Heat to Aid The Drying Process

The element of heat is crucial to the success of any water damage restoration job. We make use of a variety heaters to dry the materials that have been damaged by water.

Electric Heaters These heaters are perfect for drying tasks which require the use of multiple heat sources. You can run multiple heaters simultaneously because of their numerous wattages.

You can also turn down or off electric heat while the job is being completed, but without impacting other heaters. In order to maximize efficiency and lower your expenses for energy it is possible to adjust the wattage of a heater and increase its wattage.

Because they emit virtually zero emissions and consume very less water Electric heaters are popular in 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 can run on propane or natural gas.

Hydronic boilers are different from electric heating in that they do not utilize forced-air for distribution of heat, which means it could be difficult to evenly heat an area using these kinds of heaters. They also operate at less temperature, which makes ideal for drying projects which require ceilings and walls to be left unattended.

In the event that electric heaters can’t be utilized, hydronic boilers can typically be utilized. They can produce radiant heat, and they can keep your drying area warm without the need of electricity.


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

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

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

Fixing Hardwood Floor Water Damage

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

The damaged subflooring first needs to be removed and repaired. Then the affected hardwood boards require sanding down or replaced. To ensure uniformity the floors must be sanded and refinished after these repairs have been made.

Carpets are susceptible to water damage

If you’ve experienced an incident of flooding in your home it could be a stressful and costly experience. You might need to change your flooring, even if you have taken the water out of the area as fast as is possible.

After spending time and money to restore your home back to its original state, it could be depressing to discover that the final results leave some things to be desired.

It is vital to identify the severity of the damage as quickly as possible. The first thing to do is to determine if the damaged part requires replacement. It is possible to clean the carpet and use it again after drying. This can alleviate any concerns about mildew growth or persistent smells.

Salvaging Carpet After a Water Damage Event

There may be stains on your carpet if the damage to your carpet was severe. Sometimes, you will have to replace your flooring to get rid of the stain. Another factor that could cause you to consider replacing your carpeting is the persistent and strong smell. It is necessary to replace your padding and carpet when this happens.

Then, consider if your flooring can be dried professionally before you decide to repair it or replace it. Professionals can aid you in determining the severity of the damage was. We can evaluate whether or not your carpet needs to be replaced or can be saved. If your carpet is already in poor shape, some drying techniques can further damage it.

Some of the considerations that will determine whether or not the carpet and padding require replacement are:

Do your carpets need to be dried and cleaned, or disinfected and cleaned professionally?

If the padding underneath your carpet is damaged, it could affect the time that your carpet is clean. Even though your carpet is dried fast, the growth of mildew can still occur if the padding underneath is not dried.

The most secure way to make sure that your carpeting is properly restored and disinfected after flooding is to employ an expert carpet cleaning service. Once the work is done, you’ll be able make an informed decision about the state of your carpet. It is also possible to decide whether you want to replace it.

Drywall that has been damaged by water

The degree of damage will determine the nature and method of drywall repair. Repairing water damage can be as simple as removing some drywall, cleaning the area, and then replacing it.

On the other side of the coin serious damages could necessitate a total wall replacement, which includes the wall studs as well as fiberglass insulation.

The drywall that is damaged by water usually harbors mold spores which can not be removed easily. Most of the time, the drywall will have to be replaced. We utilize moisture testing tools to assess the extent of the moisture. This allows us to identify the areas that are damaged and keep costs restricted to only necessary damaged areas.

It also causes structural damage because it causes the material to expand and shrink. Once the wood is moistened with water, it’s a lot easier to break. If the water remains for a prolonged time, it could cause an abundance of rot on the wood which can cause it to crack easily.


In order to counteract this issue, it’s important for homeowners and building owners to address structural damages from water-related issues with their property immediately after a flood or water damage event.

Foundation Water Damage

There are a variety of reasons that water damage can affect the foundation of a home. While not all water issues cause structural damage, it is important to address foundation issues as quickly as is possible in order to avoid any future structural damage.

Foundation water damage can result in a myriad of problems based on how it’s treated. It can lead to serious structural damage if not addressed quickly.


Roof Water Damage

Like foundation water damage, roof water damage is also fairly common after natural catastrophes. Roof damage can cause roof leaks and also damage the foundations of a house or house.

Leaking roofs are costly and have serious disadvantages. Roof leaks can lead to mold growth and can be fatal. A leaking roof may also affect the roof truss structure and cause structural damage to the roof.

Leaks in the ceiling can cause your rafters to decay and soften if you do not take action immediately. Electrical faults are also common in the case of roof water damage which could cause an electrical fire. There are many reasons to have your roof water damage taken care of promptly following a flood or any other unexpected damage.

HVAC Water Damage

If your HVAC system starts to fail or brand new equipment is found to be inoperable, it can result in structural damage to your house. You are putting your home and business at risk by not having HVAC. The growth of mold can lead to a number of very serious health problems.

Damage to Pipes from Water

Damage to pipes typically caused due to a pipe burst within your home. If you’ve discovered a leak, it is essential to contact an expert to stop the water from creating structural damage.

A ruptured pipe can result in serious damage. The water could enter your home through broken pipes, causing extensive damage. This could lead to structural damage.

When you see damaged water pipes stop the supply of water.

How much does it cost to restore the water damage?

Water damage restoration cost per square foot

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

Is water damage insured by the homeowner’s insurance?

If the cause of the damage was accidental and sudden, homeowners insurance policies generally cover it. The Insurance Information Institute states that homeowners insurance will provide for the repair or replacement of broken windows however, it does not cover damage caused by neglect.

Damage from neglect may be described as wear and tear on a surface or object due to exposure, lack of regular maintenance or general wear and tear. According to the US-based Insurance Information Institute, homeowners insurance will not cover damages due to neglect.

A homeowner’s insurance policy will not be able to cover damage to water due to flooding. Rather, a flood policy is required. Mortgage lenders might require flood policies in certain areas. Flooding can occur due to storms, flooding ground, overflowing bodies of water, or overflowing or surging bodies like streams, lakes, rivers and oceans.
