Water damage restoration service – San Leandro

Building owners in San Leandro get hit with burst pipe damage on a regular basis. Whether you’ve suffered from a natural disaster or a localized catastrophe such as a ruptured pipe, 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 through a storm, flood, or burst pipe. Sometimes, the damage is obvious and obvious, sometimes it is minor or hidden.

It is more complicated than just drying out the interior of the building to repair water damage. Modern techniques for water damage repair like Critical Control, can often mitigate damage that would otherwise require a complete structural replacement.

Water Damage Restoration Guidelines are Available Contact for a Professional

Many times, homeowners or builders try to fix water damage by using DIY solutions that can be discovered on the internet. This is a bad idea. The management of water damage is in accordance with established guidelines. These guidelines require the knowledge and skills of professionals. These guidelines can be found in the IICRC Standard Reference Guide, or Professional Water Damage Restoration book. This guide is necessary to ensure the professional standardisation of instances involving water damage to buildings or homes, and the risks associated with it.

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

There are many reasons that water damage professionals should follow these guidelines. In certain situations, an Indoor Environmental Professional (IEP) is essential. An IEP is a professional who has the knowledge and experience to evaluate the condition of a place and collect samples, conduct lab tests, and then advise us on the category of water damage.

This is especially important when the building’s occupants might be at risk, there is a possibility of negative health effects, the occupants have a desire to know the suspected contaminants or have another reason for concerned about contamination.

Categories and classes of Water Damage


Water damage restoration projects are classified according to category and class, based on the severity of the invasion of water.

The class has to do with how contaminated the water that enters the structure has been. Category 1 implies that the water is from a clean source such as a water source that burst, or a sink or tub.

Category 2 water has significant levels of contaminants and could cause illness if it is ingested or contacted. This could include water that is not obvious as a threat, such as the discharge from washing machines and spills from toilets.

The water in Category 3 is highly contaminated meaning that it can contain toxic, pathogenic or any other harmful agent in it. This usually means contamination by toilet backflows following the trap for toilets, seawater, water flooding from rivers and streams, or any other source of water that comes from the exterior of the building. This kind of water could contain heavy metals, pesticides and regulated substances as well as toxic substances within it.


The IICRC has also developed classes to follow when measuring the amount of water intrusion on your property. This is basically an outline of the amount of water a building or house ought to be.

Class 1 is the smallest amount of water and absorption. This is when water is in contact with less than 5% of construction substances which absorb water. This is because the majority of substances affected by water do not absorb or hold water. Concrete or plaster, masonry and finished/coated wood are just a few examples.

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

The porous materials, like carpet, insulation , and fiberboard which make up the class 3 make up around 40 percent of the floor, wall and ceiling materials. This includes around 40% in class 3. Other materials like concrete or plaster that don’t absorb water have not been affected in any way.

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

How do you dry a water damaged Home or Building Works


Three ways to remove water from buildings are physical extraction, dehumidification and evaporate. The elimination of water that is liquid is at least 500 times more effective than just having to put up with dehumidifiers or air movers. The quicker the structure dries the better. The quantity of materials to be extracted will influence both dehumidification and extraction techniques.

Water damage professionals use different extraction techniques. Some of our tools include wands, subsurface extraction tools as well as self-propelled tools and vacuum squeezers.

Forcible Evaporation

The remainder of the moisture gets then dried by high-speed airmovers after the maximum amount of water is taken away.

If an object is wet or submerged in water, it absorbs some water or moisture. The result is that the object becomes damp or wet.

The level of saturation is described as the point where it is impossible to hold any additional moisture. A higher humidity indicates that the air is more close to saturation.

The evaporation phase is when water molecules change from an in liquid state to a gaseous state. This is called evaporation.

In this way the object no longer absorbs additional moisture from the atmosphere. The saturation point is the point at which evaporation begins. When saturation is reached, drying will begin.

In the evaporation stage the highly efficient air moves dry the object on two sides. They create strong airflow which is directed by a filter system.

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

The object is dried using airmovers around 10 times faster than in natural conditions where no air mover was used.

Airflows with high velocity removes the moisture from the surface and absorbs the moisture pulled out by the air movement.

Using Heat To Assist The Drying Process

A key component of any restoration project is the use of heat. We make use of a variety heaters to dry the materials that have been damaged by water.

Electric Heaters: These heaters can be used for drying jobs which require multiple sources of heat. They are available in several different energies, which lets you operate multiple heaters at once.

Electric heat is also capable of being turned down or off when the work is in process, without affecting your other heaters. To increase efficiency and reduce your expenses for energy it is possible to adjust the wattage of one heater, while also increasing its wattage.

Electric heaters are common in restoration work since they emit virtually no emissions and use minimal amounts of water. They take longer to heat up and require more time for drying.

Hydronic Bioler (TES),: These boilers are able to heat quickly and release very little CO2. They can be run on natural gas or propane.

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

In the event that electric heaters can’t be utilized, hydronic boilers can often be used. Because they are extremely efficient at producing radiant heat, they are able to keep your drying space warm even without an electrical power source.


To dry houses and buildings that have been damaged by water damage, we make use of low Grain Refrigerant (LGR) Dehumidifiers.

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

In addition to removing water from the air like an LGR Refrigerant Dehumidifier does it, the dehumidifier for your home will also get rid of up to 99% of airborne mold spores in the air, by removing condensation.

Fixing Hardwood Floor Water Damage

It is essential to take away flooring that has been damaged by water to ensure that repairs can be made starting from the subflooring.

The subflooring must be removed and repaired prior to. The hardwood floors damaged must be replaced or sanded. In order to ensure a uniform appearance, all floors should be sanded and repaired after these repairs have been completed.

Carpets are vulnerable to water damage

Floods can cause severe damage to your home and can make repairs difficult and expensive. Even if the water is taken away from the affected area immediately, there is still a chance that you will have to eventually replace the flooring.

After spending time and money to restore your home back to its pre-flood condition, it would be depressing to discover that the finished results leave something to be desired.

It is essential to assess the extent of the damage as fast as you can. The first thing to do is determine if the affected area needs to be replaced. There is a good chance that the carpet will be cleaned and used once it is dry, and this cleaning will help eliminate some of the worries about the growth of mildew and lingering odors.

Salvaging Carpet After a Water Damage Event

If the water damage is very extensive, it is possible that you will have noticeable marks on your carpet. There are times when you have to replace your flooring to eliminate these stains. A strong, lingering odor may also be the reason to change your carpet. You will need to replace your carpet padding and padding in the event of this.

The next step to determine whether or not you need to replace your carpeting is to determine whether your floor is able to be dried and cleaned professionally. If you have a reliable company do the cleaning, then you will have a better understanding of how serious the damage was. We will be able to evaluate whether or not your carpet should be replaced or can be salvaged. Keep in mind that some methods employed for drying may cause further damage to the carpet when it is already in bad condition.

The main factors that will 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 can be affected if the padding beneath it is damaged. Although your carpet has been dried quickly, mildew growth is still possible if the padding underneath is not dried.

The safest way to ensure that your carpet is restored and disinfected after a flood is to hire a professional carpet cleaning company. After the company completes their work, you will be in a position to make an informed decision about the condition of your carpeting and decide whether or not you need to replace it.

Drywall damaged by water

The degree of damage determines the kind and technique of repair. Repairing water damage can be as easy as removing the drywall section, cleaning it, and after that, replacing it.

On the other hand of the coin severe damage could require a complete wall replacement, including walls studs and fiberglass insulation.

Water damaged drywall often harbors mold spores which can not be easily removed. Therefore, in the majority of cases, drywall will need to be replaced. We use moisture testing tools to determine the amount of the moisture. This allows us to isolate damaged areas and limit costs to only necessary damaged areas.

The water can also cause structural damage, as it causes the material to expand and contract. When the wood is saturated with water, it’s much more difficult to break. If the water is left to sit for a lengthy time, there can be a significant amount of rot within the wood which can make it break easily.


To avoid this problem, it’s essential for homeowners and building owners to take care of structural damage caused by the effects of moisture on their property immediately after an event like a flood or water damage occasion.

Water Damage to the Foundation

The damage caused by water to a house’s foundation can be caused by a number of reasons. While not every water issue cause structural damage, it is important to correct foundational issues as soon as possible to prevent future structural damage.

The damage caused by water in the foundation could cause many different problems depending on how it is addressed. If the problem isn’t treated promptly, it could result in structural damage that is severe.


Roof Water Damage

Like foundation water damage, roof water damage is also very common after natural catastrophes. As well as causing roof leaks, roof damage can also result in problems with the walls or foundations of a the building.

Roof leaks can be very expensive and could have major disadvantages. A leak on the roof may cause mildew and mold to grow, which can cause death. The leaks in the roof could also cause damages to the roof truss.

Leaks in the ceiling can cause your rafters’ to degrade and become soft if you don’t deal with them right away. Damage to your roof can be caused by electrical faults that can cause an electric fire. These are all good reasons to get roof water damage dealt with immediately following a flood, or any other unexpected damage.

HVAC Water Damage

Your home may be damaged structurally if your HVAC system fails or faulty equipment is installed. Without HVAC it is exposed to the interior of your home or business to all kinds of problems. It can lead to severe health issues.

Damage to the Pipe Water

If you’re experiencing pipe water damage, it is most likely coming from a ruptured pipe inside your home. Once you’ve determined there’s an issue, it’s important to call a professional to stop the water from causing structural damage.

A pipe that bursts can cause devastating damage. If your pipes fail they can let water into your home, causing severe damages and necessitating repairs for water damage – a process that can bring with it structural damages.

When you see water damage to your pipe that is not repaired close off the supply of water.

What is the cost of the restoration of water damages?

Water damage restoration cost per square foot

Based on the square foot the repairs and cleanup expenses vary. National Flood Services has the below pricing breakdown per square foot.

Can Water Damage be covered By the Homeowner’s Insurance?

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

Damage from neglect may be defined as wear and tear of the surface or object because of exposure, insufficient preventative upkeep or general deterioration. According to the American-based Insurance Information Institute, homeowners insurance doesn’t cover damage caused by negligence.

A homeowner’s policy does not be able to cover damage to water caused by flooding. Flood insurance is mandatory. Mortgage lenders might need flood insurance in specific areas. Flooding can occur due to floods, storms or overflowing bodies of water, or overflowing or surging bodies like streams, lakes, rivers and oceans.
