Water damage remediation – Golden Gate Business System

Building owners in Golden Gate Business System experience flood damage regularly. Whether you’ve been affected by 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 seeps into a building or residence by way of a flood, storm or burst pipe. Sometimes the damage is overt and evident, while other times it is minor or hidden.

It is more complicated than just drying out the interior to repair water damage. With the most modern techniques for water damage remediation, often restorers like Critical Control can mitigate damage which would in the past would have required complete structural replacement, in other words, demolish and rebuild.

Water Damage Restoration Guidelines Are In Place so call an Professional

Oftentimes, home or building owners attempt to deal with water damage using DIY solutions available online. This is a bad idea. The management of water damage is according to established guidelines. These guidelines require the skills and tools of professionals. These guidelines are found in the IICRC Standard Reference Guide, or Professional Water Damage Restoration book. This guideline is essential to ensure professional standardisation of instances involving water damage to houses or buildings, and the risk associated with it.

The IICRC guidelines help restoration experts like Critical Control to evaluate the category and class of damage to each project.

There are many reasons why water damage experts should adhere to these guidelines. There are certain situations that require the use of an Indoor Environmental Professional (IEP). An IEP is a professional who has the experience and knowledge to examine a site for contamination and collect samples, conduct lab tests, and then advise us on the category of water damage.

This is especially important in cases where the building’s inhabitants could be high risk, there are a chance of adverse health effects, the people who live there are required to determine the suspected contaminants, or some other reason to raise concern over contamination.

Water damage through categories and classes


Restoration projects for water damage are classified into two categories according to the extent of the water infiltration is.

The water that entered the building was classified according to the degree of contamination. Category 1 means that the water originates from a clean source such as burst water supply, or tub or sink.

The category 2 water has high levels of contaminants and is likely to cause discomfort of illness when inhaled or consumed. These sources can be water that isn’t obvious as a danger, such as the discharge from washing machines and overflows from toilets.

The water in Category 3 is highly affected, which means that it may contain toxic, pathogenic, or other harmful agents within it. Usually this means contamination by sewage, toilet backflows after the trap for toilets or a flood of seawater from streams and rivers, or any other water arising from the building exterior. The water could be contaminated by pesticides, heavy metals or toxic substances.


It is also possible to use the IICRC’s courses to determine how much water has penetrated your property. This system basically sets guidelines for the level of saturation of the building or home.

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

Class 2 indicates that there is a significant absorption of water and intrusion. It is approximately 5 to 40% of combined ceiling, floor, and wall are composed 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 floor, wall, and ceiling surfaces are porous such as carpet, insulation, fiberboard, etc. and other materials that don’t absorb water like concrete or cement have not been adversely affected.

Class 4 refers to the fact that water has been deeply trapped in the materials that can not easily absorb water like plaster, wood, concrete and bricks and mortar. This requires more drying time and special drying techniques.

How do you dry a water Damaged House or Building


Physical extraction, dehumidification, and evaporation are three methods of removing water from buildings. Eliminating liquid water is, at a minimum, 500 times more efficient than air movers. The faster the structure is dried, the more efficient. The quantity of materials to be extracted can affect both dehumidification and extraction techniques.

Water damage experts employ a variety of extraction methods. We employ a range of equipment, such as subsurface extraction tools and self-propelled tools.

Forcible Evaporation

Once all water has been removed, any moisture remaining is dried using high-velocity airmovers.

When an object gets wet or submerged in water, it absorbs some of the water or moisture. The object gets wet or damp because of this.

The degree of saturation is known as the point at which it is impossible to hold any additional moisture. The higher the humidity, the more close the air is to saturation.

The evaporation process occurs the moment when water molecules shift from the state of liquid to a gaseous form. This process is known as evaporation.

This means that the object has stopped absorbing moisture from the atmosphere. The saturation point is the point of evaporation. As soon as saturation has been reached the drying process commences.

High-efficiency air movers dry objects in two areas during the evaporation phase. They generate a large air flow over the surface of the object, that is controlled through a filter system that completely covers the surface of the object.

An air mover can move between 10 and 20 percent more air than an ordinary fan, or a standard household fan.

The item is dried using airmovers around 10 times faster that in the natural environment where there was no air movement.

Airflows with high velocity leaves the surface dry and absorbs moisture that is drawn out by air movement.

Using Heat To Assist The Drying Process

Heat is an important component of any restoration task. In order to dry out any materials which have been affected by water, we employ various kinds of heaters.

Electric Heaters These heaters are perfect for drying tasks that require various heating sources. This is because they can be found in various wattages, allowing you to run multiple heaters simultaneously.

Electric heat is also adjustable, allowing it to be reduced or turned off during the process, without impacting your other heaters. To maximize efficiency and lower your energy bills you can alter the wattage of one heater, while also increasing its wattage.

Since they produce virtually zero emissions and consume very less water They are popular in restoration projects. However, the only drawback is that they take longer to heat up, requiring more time to dry process overall.

Hydronic Bioler (TES),: These boilers heat up quickly and emit very little carbon dioxide. They typically operate using propane or natural gas.

Hydronic boilers are different from electric heating in that they don’t utilize forced-air for distribution of heat, which means it could be difficult to evenly heat a large area using these kinds of heaters. They can also be used for dry work that does not require ceilings or walls to remain in place.

When electric heaters cannot be utilized, hydronic boilers can typically be utilized. Because they are extremely efficient at producing radiant heat, they can easily keep your drying area warm even without an electric power source.


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

The LGR Home Dehumidifier can remove 170 pints of water in a damp building that has been severely affected by water damage every all day, every hour of the day.

The dehumidifier at home is able to remove water from the air in the same manner it does an LGR Refrigerant Dehumidifier. It can get rid of up to 99 percent of airborne mold spores by removing condensation.

Repairing Wood Floor Water Damage

It is crucial to get rid of flooring that has been damaged by water so that repairs can be made starting from the subflooring.

The subflooring has to be removed and repaired prior to. The damaged hardwood boards need to be sanded down or replaced. When the repairs are finished and the floor is finished, it should be sanded, refinished and polished to ensure a uniform appearance.

Water Damage To Carpeting

Floods can cause serious destruction to your home and can make repairs difficult and expensive. Even if the water has been taken away from the affected area right away, there’s an opportunity that you will have to eventually replace the flooring.

After investing time and money in restoring your home to its pre-flooding condition, it will be depressing to discover that the finished results leave something to be desired.

Because of this, it is crucial to determine the severity of the damage as soon as possible. First thing to do is to determine if the damaged area requires replacement. There’s a good chance that the carpet can be cleaned and still used after it has dried and the cleaning process will eliminate some of concerns regarding the growth of mildew and lingering odors.

Salvaging Carpet After a Water Damage Event

There may be stains on your carpeting if the damage from water was serious. There are times when you have to replace your flooring in order to remove the stain. A strong, lingering odor could also be a reason to change your carpet. If you find this to be the case it is likely that you’ll have to replace the padding and carpet.

Then, consider if your floor can be professionally dried before you decide to replace it. Professionals will be able to assist you in determining how severe the damages were. Our company will assess your carpet and determine whether it is best to replace it or salvageable. Keep in mind that some of the techniques employed to dry the carpet can cause further damage to the carpet when it is already in poor condition.

The main factors that determine whether or not the carpet and padding should be replaced include:

Are your carpets dry and cleaned, or disinfected and cleaned professionally?

The carpet’s ability to stay fresh can be compromised if the padding underneath it is damaged. Although your carpet may have dried quickly, mildew growth can still occur in the padding beneath if it isn’t dried.

A professional carpet cleaning service is the best way to make sure your carpeting is dry and clean after an event of flooding. Once the company has completed their job, you’ll be in a position to make an informed decision about the state of your carpet and determine whether or not you need to change it.

Drywall damaged by water

The extent of damage will determine the type and method of drywall repair. Repairing water damage can be simple as taking out a section of drywall then cleaning it and after that, replacing it.

On the other hand of the coin, serious damages could necessitate a total reconstruction of the wall, which could include walls studs and fiberglass insulation.

Water damaged drywall often harbors mold spores that can’t be easily removed. Most of the time the drywall will need to be replaced. We utilize moisture testing tools which allow us to identify where and how extensive the moisture has become. This allows us to identify damaged areas and limit costs to those areas that are only damaged.

Water can cause structural damage as well, as it causes the material to expand or expand or contract. Once the wood is moistened by water, it becomes much more difficult to break. The wood will become brittle if it is left to dry in water for too long.


To prevent this problem, it’s essential to homeowners and property owners to address structural damages from the effects of moisture on their properties immediately following the water or flood event.

Water Damage to the Foundation

The damage caused by water to a house’s foundation can happen due to a number of reasons. While not all water issues cause structural damage, it is important to fix foundational problems as quickly as you can in order to avoid any future structural damage.

Water damage to the foundation can result in a myriad of issues based on the way it’s dealt with. It can lead to serious structural damage if it isn’t taken care of promptly.


Roof Water Damage

Roof water damage can also result from natural disasters, just like foundation water damage. Along with creating roof leaks damage can also result in problems with the walls and the foundation of a house or building.

Leaking roofs are extremely expensive and could have major disadvantages. A leak in the roof can cause mildew and mold to grow, which can cause death. Leaks in the roof may also result in damages to the roof truss.

If you don’t fix leaks in your ceiling immediately the risk is that the rafters to decay and then soften. Electrical problems are also common in roof water damage, that can lead to the possibility of an electrical fire. All of these are good reasons to have roof water damage repaired quickly after a flood or other sudden damage.

HVAC Water Damage

Your home could be damaged by structural damage if the HVAC system fails or is defective equipment is installed. If you do not have HVAC, you are opening the interior of your house or business to all kinds of problems. The growth of mold can cause severe health issues.

Pipe Water Damage

If you have pipe damage due to water, it is most likely coming from a burst pipe in your home. Once you’ve determined there’s a leak, it is crucial to get an expert to stop the water from creating structural damage.

Pipes that burst can cause a number of damages. The water could enter your home via broken pipes, causing severe damage. This could lead to structural damage.

When you see broken pipe water damage, shut off the water supply.

What is the cost to repair the water damage?

Water damage restoration cost per square foot

Repair and cleanup costs will vary depending on the square footage you own. National Flood Services has the below pricing breakdown for each square foot:

Are water damages covered by homeowners’ insurance?

The homeowner’s insurance policies are generally used if the damage is unexpected and accidental. The Insurance Information Institute states that homeowners insurance can provide for the repair or replacement of broken windows however, it does not cover damage due to negligence.

Damage caused by neglect can be described as wear and tear of the surface or object due to exposure, lack of preventative upkeep or general deterioration. According to the US-based Insurance Information Institute, homeowners insurance will not cover damages from neglect.

A homeowners policy would not cover water damage due to flooding. A flood policy is required. Mortgage lenders might require flood insurance in some regions. Flooding can happen due to storms, ground that is saturated to the point of overflowing or surging bodies of water such as lakes, rivers, ponds oceans, streams when combined with strong winds.
