Water damage remediation – San Leandro

Building owners in San Leandro 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.

The most common cause of water damage is when water gets into a structure or residence by way of a flood, storm or ruptured pipe. Sometimes the damage is evident and obvious. In other instances, it’s subtle or under-reported.

It is more complicated than just drying the interior to repair water damage. With the most modern water damage remediation tactics typically restorers such as Critical Control can mitigate damage which previously would have required total structural replacement, in terms of demolition and rebuild.

Water Damage Restoration Guidelines are Available for your reference. Call an Professional

Oftentimes, home or building owners attempt to address water damage using DIY solutions found on the internet. This isn’t a good idea. There are guidelines to deal water damage that depend on the skills and tools of professionals. The guidelines can be included in the IICRC Standard Reference Guide, or Professional Water Damage Restoration book. This guide is required 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 firm, is able to use IICRC guidelines to assess the type and extent of each project’s damage.

There are many reasons that water damage professionals must adhere to these guidelines. There are instances that require the use of the services of an Indoor Environmental Professional (IEP). An IEP is an individual with the knowledge and knowledge to assess an area for contamination collect samples, perform lab tests and offer us suggestions on the type of water damage.

This is crucial in situations where the occupants of the building could be high risk, there are a chance of adverse health consequences, or the occupants express a need to identify the suspected contaminants or any other reason for concerns about contamination.

Water destruction caused by types and classes


Water damage restoration projects are classified into categories and class depending mostly on the extent of the flood.

The classification has to do with how polluted the water entering the structure was. Category 1 means that the water originates from a clean source such as burst water supply, or tub or sink.

The category 2 water contains significant amounts of contaminants, and could be able to cause discomfort of illness should it be consumed or ingested. The sources could be waters that are not readily apparent as a threat, such as the discharge from washing machines or overflows from toilets.

Water in Category 3 can be classified as highly contaminated. It could contain pathogenic, toxic, or any other hazardous substances. Most often, this is due to contamination from sewage, toilet backflows after the trap for toilets, seawater, water flooding from rivers and streams, or any other source of water that comes from the building exterior. The water in this category could contain heavy metals, pesticides and regulated substances as well as toxic chemicals in it.


The IICRC has also established classes that we follow in determining the level of water intrusion to your property. This is basically an indication of how much saturated a structure or house is.

Class 1 is the smallest amount of water and absorption. It is the case when water is in contact with around 5% or less with construction materials that absorb water. This is because the majority of substances that are affected by water do not retain or absorb water. Concrete and masonry, as well as plaster and finished/coated wood are just some of the examples.

Class 2 is a term used to describe water absorption and intrusion. This is about 5 to 40% of the combined ceiling, floor, and wall are composed of low evaporation materials such as plaster, concrete, wood, or bricks and mortar.

Class 3 means that about 40 percent or more of wall, floor and ceiling materials are porous materials like fiberboard, insulation, carpet and so on. and other materials that don’t absorb much water such as concrete or cement have not been negatively affected.

Class 4 indicates that water has become deeply stuck in materials that do not easily absorb water like plaster, wood, concrete and masonry. This requires special drying techniques and longer drying time.

How Drying a Water Damaged Home or Building Works


Physical extraction, dehumidification, and evaporation are the three main methods to remove water from a structure. Removal of liquid water is at minimum 500 times more efficient than simply having to put up with dehumidifiers or air mover. The faster the structure is dried, the more efficient. The amount of stuff to be extracted will influence both dehumidification and extraction techniques.

Professionals dealing with water damage employ an array of extraction techniques. We have tools for subsurface extraction, wands as well as self-propelled tools and vacuum squeegees.

Forced Evaporation

After the water is removed, the remaining moisture is dried with high-speed airmovers.

If an object is wet or submerged in water it absorbs some water or moisture. The object gets wet or damp due to this.

The level of saturation is referred to as the point at which it becomes impossible to contain any more moisture. The greater the humidity, the closer the air is getting to saturation.

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

In other words, the object will no longer absorb additional moisture from the air. We call that saturation point the point at which evaporation begins. When saturation is reached, drying starts.

In the evaporation stage the highly efficient air mover dry the object from two sides. They produce a powerful airflow over the surface of the object which is directed by a filter system that completely covers the surface of the object.

An air mover moves around 10 to 20 times more air than a fan , or the typical household fan.

The item is dried by air movers approximately 10 times faster that in natural conditions in which no air mover was used.

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

Utilizing Heat To Aid In The Drying Process

Heat is an important component of any restoration project. In order to dry out any materials that have been affected by water, we make use of a number of different types of heaters.

Electric Heating Equipment: These heaters can be used to dry tasks that require multiple heat sources. They can be found in various energies, which lets you operate multiple heaters at once.

It is also possible to turn off or turn off the electric heater when the task is done, without affecting other heaters. In order to maximize efficiency and lower your expenses for energy it is possible to adjust the power of one heater while increasing it’s power.

Electric heaters are common in restoration jobs since they emit virtually no emissions and require minimal amounts of water. The only downside is that they take longer to heat up, requiring longer drying time. process generally.

Hydronic Bioler (TES): Hydronic boilers are also very efficient in heating up quickly and generating low emissions. They can be powered by propane or natural gas.

Hydronic boilers differ from electric heating because they don’t use forced-air heat to distribute heat. This makes it difficult to evenly heat large areas with these heaters. They also operate at less temperature, which makes them ideal for drying jobs that require walls and ceilings to be left unattended.

They are also commonly employed when there isn’t enough electricity to run electric heaters. They are capable of producing radiant heat, and they can keep your drying area warm without the need of electricity.


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

The LGR Home Dehumidifier can extract 170 pints moisture from damp structures that have experienced extensive water damage within 24 hours.

In addition to removing water out of the air such as an LGR Refrigerant Dehumidifier does it, the dehumidifier for your home will also eliminate as much as 99% of airborne mold spores the air, 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 subflooring must be removed and repaired first. Next, the hardwood boards damaged need to be replaced or sanded. To ensure uniformity, all floors should be sanded, then repaired after these repairs have been made.

Carpets are susceptible to water damage

Floods can cause significant damage to your home and cause it to be difficult and expensive. Even if the water is eliminated from the area immediately, there is an opportunity that you’ll need to eventually replace the flooring.

After investing time and money in restoring your home back to its pre-flood condition, it would be devastating to find that the finished results leave some things to be desired.

It is crucial to determine the extent of the damage as fast as you can. The first thing to do is to determine if the damaged part requires replacement. There’s a possibility that the carpet could be cleaned and still used after drying and the cleaning process can help to eliminate the worries about the growth of mildew and the lingering smells.

Salvaging Carpet After a Water Damage Event

There could be staining on your carpeting , especially if the damage to your carpet was extensive. In some cases, the only way to get rid of the stains is to replace the flooring. Another factor that could cause you to think about replacing your carpeting is the persistent and strong smell. If you find this to be the case, then you will likely need to replace both your carpet and padding.

Check to see if the floor can be professionally dried before you decide to replace it. Professionals will be able to aid you in determining the severity of the damage was. We can evaluate whether or not your carpet should be replaced or saved. If the carpet you have is damaged, a few drying techniques can further damage it.

Many factors determine the need for padding or carpet need to be replaced.

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

The carpet’s ability to stay clean can be affected if the padding beneath it has been damaged. Even though your carpet may be dry however the risk of mold growth is there if the padding underneath it has not dried as well.

The best way to be sure that your carpeting is properly restored and disinfected after an event of flooding is to engage an expert carpet cleaning service. After the company completes their work, you will be in a position to make an informed decision about the state of your carpet and determine whether or not to change it.

Drywall damaged by water

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

The opposite of this is that serious damage could need to be repaired completely, including the wall studs and fiberglass insulation.

There are spores of mold in drywall damaged by water that is hard to get rid of. So in most cases drywalls will have to be replaced. We utilize moisture testing tools that help us determine where and how extensive the water has grown. This allows us to identify damaged areas and limit costs to only the areas that are damaged.

Water can also cause structural damage, because it causes the wood to expand or contract. After the wood has been moistened with water, it’s much easier to break. If the water remains for a lengthy time, it could cause a significant amount of rot within the wood which can cause it to crack easily.


This issue can be prevented by owners of buildings and homeowners taking immediate action to fix structural damage from moisture-related problems with their property following an event like a flood or water damage.

Water Damage to the Foundation

There are a variety of reasons that water damage could affect the foundation of a home. Although not all water problems cause structural damage, it’s crucial to address foundation problems as quickly as you can in order to avoid any further structural damage.

Water damage to the foundation can result in a myriad of problems based on how it’s treated. It can lead to serious structural damage if not taken care of promptly.


Roof Water Damage

Similar to foundation water damage roof water damage is very common after natural disasters. Roof damage can cause roof leaks, and can also cause damage to the foundations of a house or home.

Leaking roofs can be extremely costly and can have significant drawbacks. The roof’s leaks could lead to mold growth and can be fatal. Leaks in the roof may cause damage to the roof truss system.

If you don’t fix leaks in your ceiling immediately, they can cause your rafters decay and soften. Electrical faults are also common in the case of roof water damage which could 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 other sudden damage.

HVAC Water Damage

If your HVAC system is failing or brand new equipment is found to be faulty, this can definitely cause the structure of your house. Your home and business at risk by not having 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. If you’ve determined there’s been a leak, it’s important for you to contact a professional to stop the water and ensure that it doesn’t cause structural damage.

A pipe that bursts can cause serious damage. If your pipes fail, water may enter your home, causing severe damage , and may require repairs for water damage – an event that could cause structural damage.

As soon as you notice damaged water pipes, shut off the supply of water.

How much does it cost to fix the water damage?

Water damage restoration cost per square foot

Repair and cleanup costs will vary depending on how many square feet you own. National Flood Services has the following pricing breakdown for each square foot:

Are water damages covered by homeowners’ insurance?

If the cause was unintentional and sudden the homeowners insurance policy will usually cover it. According to the Insurance Information Institute, homeowners insurance may cover repair or replacement for a damaged window, however, not if the damage occurs as a result of negligence.

Neglect can be described as damage to an object or surface that is caused by the weather, lack of maintenance or general deterioration. According to the Insurance Information Institute, a US-based Insurance Information Institute, homeowners insurance will not cover damages due to neglect.

If the damage to your property resulted from a flood, the event is not covered under a homeowners policy. A flood policy would be required. In some regions, flood policies are required by mortgage lenders. Flooding can occur as a result of storms, over-saturated ground, and surging or overflowing bodies water, such as rivers, ponds, lakes rivers, oceans, and streams when combined with strong winds.
