Water damage remediation – San Anselmo

Building owners in San Anselmo experience burst pipe 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.

When a storm, flood, or burst pipe causes water to get into a home or structure, water damage occurs more often than not. Sometimes, the damage is obvious and obvious, sometimes it is minor or hidden.

Water damage remediation is much more complex than simply drying out the interior. Modern techniques for water damage repair like Critical Control, can often minimize damage that otherwise would have required total structural replacement.

Water Damage Restoration Guidelines are in place and you can call an Professional

Many times, homeowners and builders try to fix water damage by using DIY methods that can be discovered on the internet. This isn’t a good idea. Water damage can be managed in accordance with established guidelines. These guidelines require the skills and tools of professionals. The guidelines are set forth in what is known as IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide is created because of the necessity for professional standardisation of situations that involve water damage to homes and buildings and the dangers they can present.

Critical Control, a restoration business, can use IICRC guidelines to help them evaluate the severity and nature of the project’s damages.

There are many reasons why professionals dealing with water damage must adhere to these guidelines. In certain situations it is necessary to employ the use of an Indoor Environmental Professional (IEP) is required. An IEP is a professional who has the experience and knowledge to examine the condition of a place take samples, perform lab tests, and then advise us on the category of water damage.

This is crucial in cases where the building’s residents are at risk or are concerned regarding contamination.

Categories and Classes of Water Damage


Restoration of water damage projects are classified by category and class depending mostly on the extent of the invasion of water.

The water that entered the structure was classified based on the degree of contamination. The first category is water that originates from a clean source such as a tub or sink or a water source that bursts.

Category 2 water has high levels of contaminants and can cause illness if it is ingested or contacted. It could include sources that may not normally seem like dangers, such as the discharges from washing machines, or overflows from toilets.

Water in the category 3 is severely polluted, meaning it could have pathogenic, toxigenic or any other harmful agent within it. This could be due to backflows of sewage, leaks from toilet traps, as well as the flooding of rivers and streams. This kind of water could contain heavy metals, pesticides that are regulated, toxic materials, or chemicals in it.


You can also utilize the IICRC’s classes to determine just how much water has penetrated your property. This is basically setting guidelines for the saturation of the structure or the home.

Class 1 means the least amount of absorption and water. This is where the water is in contact with approximately 5percent or less of building materials that absorb water. This is due to the fact that most of the materials that are affected by water don’t absorb or hold water. Examples are concrete, finished/coated wood, plaster or masonry.

Class 2 means that there is substantial absorption of water and intrusion. It is approximately 5% to 40% of combined ceiling, floor, and wall comprised of low-evaporation materials such as plaster wood, concrete, or masonry.

The porous materials, such as carpet, insulation , and fiberboard, that make up Class 3 are approximately 40 percent of the floor, wall and ceiling materials, including about 40% in class 3. Other materials, such as concrete or plaster that don’t absorb water have not been affected in any way.

Class 4 means that water is stuck in materials that do not easily absorb water as wood, plaster, concrete and bricks and mortar. This will require more time to dry and special drying methods.

How to dry a water damaged Building or House


Physical extraction, dehumidification and evaporation are considered three ways to get rid of water from buildings. Eliminating liquid water is, at a minimum, 500 times more effective than airmovers. The quicker the structure dries the more efficient. Both extraction and dehumidification methods are affected by how much material is being removed.

Water damage professionals use an array of extraction techniques. We make use of a variety of tools , including self-propelled and subsurface extraction tools.

Forced Evaporation

The remaining moisture is then dried using high-speed air movers once as much water as possible is removed.

A submerged object absorbs moisture and water when it’s wet. The object gets wet or damp because of this.

Saturation is defined as the point at which it becomes impossible for the air to contain any moisture. A higher humidity indicates that the air is closer to saturation.

In the evaporation stage in which water molecules are ejected from a liquid state to a gaseous state. This is referred to as evaporation.

This means that the object has stopped absorbing moisture from the atmosphere. This is known as the saturation point. the point of evaporation. Once saturation is reached, drying starts.

High-efficiency airmovers dry the object on two sides in the evaporation phase. They create strong airflow which is controlled by a filter system.

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

Air movers dry the object about 10 times faster than the natural environment, in which no air mover is used.

The high-speed airflow dry the surface of the object and draws in the water that was drawn away by the air movers.

Using Heat To Assist The Drying Process

Heat is an important component of any restoration project. We make use of a variety heaters to dry out materials that are damaged by water.

Electric Heaters They are ideal for drying jobs that require several different heat sources. They can be found in various power levels, which allows you to use multiple heaters at the same time.

You can also reduce or turn off the electric heater as the work is done, and not affect other heaters. This means that you can lower one heater, while increasing the power of another one to improve efficiency and reduce your cost of energy.

Electric heaters are a common feature in restoration projects since they emit virtually no emissions and require minimal amounts of water. The only issue is they take longer to get hot, which requires more time to dry process overall.

Hydronic Bioler (TES): They are also extremely efficient in heating up quickly, while still producing low emissions. They can be run on natural gas or propane.

Hydronic boilers are different from electric heaters because they don’t use forced-air heat to disperse heat. This makes it difficult to evenly heat large areas by using these heaters. They can also be utilized for dry work that does not require ceilings or walls to be in their place.

They are also commonly used when there is no electricity to power electric heaters. Because they are extremely efficient in producing radiant heat, they are able to 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 and homes that have experienced water damage.

The LGR Home Dehumidifier is capable of extracting 170 pints water from 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 way as an LGR Refrigerant Dehumidifier. It can also remove the 99 percent or more of the airborne mold spores through the elimination of condensation.

Fixing Hardwood Floor Water Damage

It is essential to take away water damaged hardwood floors to ensure that repairs can be completed starting from the subflooring.

Subflooring that is damaged first has to be removed and replaced. The hardwood floors affected need to be sanded or replaced. When the repairs are finished and the floor is finished, it should be sanded and then refinished to guarantee a uniform appearance.

Carpets are susceptible to water damage

If you have experienced a flood in your home, it can be a costly and stressful experience. It is possible that you will need to replace your flooring, even if you have taken the water out of the area as quickly as is possible.

It’s devastating to discover that your house isn’t in top state after having spent many hours and dollars to fix it.

It is essential to assess the extent of damage as soon as is possible. One of the first things that needs to be addressed is whether the affected area should be replaced. There’s a chance that the carpet will be maintained and cleaned after it has dried, and this cleaning 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 severe. Sometimes, you will have to change your flooring to remove the stain. Another reason that might prompt you to think of replacing your carpeting is a strong and lingering odor. If it is then you may have to replace your carpet and padding.

Next, determine if your floor can be dried professionally before deciding whether you want to repair it or replace it. If you have a reliable company do the cleaning, you’ll have a better understanding of how severe the water damage was. We can assess whether the carpet should be replaced or salvaged. Keep in mind that some methods employed for drying may further damage the carpet if it is already in bad condition.

A variety of factors can determine the decision of whether padding or carpet need to be replaced.

Are your carpets dry or cleaned professionally?

The carpet’s ability to stay clean can be affected if the padding underneath it is damaged. Although your carpet might have dried quickly but the chance of mildew development is there if the padding underneath isn’t dried out as well.

The best way to be sure that your carpet is cleaned and disinfected following flooding is to employ a professional carpet cleaning company. Once the cleaning is complete you’ll be able to take a shrewd decision on the condition of your carpet. You can also decide whether to replace it.

Drywall that has been damaged by water

The extent of damage will determine the nature and way to repair drywall. Repairing water damage may be as simple as removing the drywall portion and then cleaning the affected area and replacing it.

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

The drywall that is damaged by water usually harbors mold spores that can’t be easily removed. Therefore, in the majority of cases the drywall needs to be replaced. We employ moisture testing tools that allow us to determine how large and where the humidity has gotten. This allows us to pinpoint areas that are damaged and limit costs to only the areas that are damaged.

Water can also cause structural damage as it causes the material to expand or contract. When the wood is saturated with water, it’s much more difficult to break. The wood will be brittle if kept in the water for too long.


This problem can be avoided by building owners and homeowners immediately taking action to repair structural damage from moisture-related problems with their property following a flood or other water damage.

Foundation Water Damage

Damage to a home’s foundation can be caused by many reasons. While not all water issues could cause structural damage, it’s important to correct foundational problems as quickly as you can to prevent future structural damage.

Water damage to the foundation can result in a myriad of problems based on how it is dealt with. If the issue isn’t treated quickly, it can cause serious structural damage.


Roof Water Damage

Similar to foundation water damage roof water damage is quite common following natural disasters. In addition to causing roof leaks, roof damage can also result in issues with the walls and foundation of a home or building.

Roof leaks are expensive and can have serious drawbacks. Leaks in the roof may result in mold and mildew to develop, which could cause death. Leakage in the roof can also cause damages to the roof truss.

If you don’t address the leaks in your ceiling promptly, they can cause your rafters decay and soften. Roof water damage can also result from electrical faults that can cause an electric fire. These are all good reasons to get roof water damage taken care of immediately following a flood, or other sudden damage.

HVAC Water Damage

Your home may be damaged by structural damage if the HVAC system fails or faulty equipment is put in place. If you do not have HVAC, you are opening the interior of your business or home to all kinds of problems. The growth of mold can cause a variety of serious health issues.

Damage to pipes caused by water

If you have pipe water damage, it is most likely coming from a burst pipe in your home. When you’ve identified an issue, it’s crucial to get an expert to prevent the water from creating structural damage.

The burst of pipes can cause number of damages. When pipes are damaged, water may enter your home, causing extensive damage and requiring water damage repair – a process that can cause structural damage.

When you see broken pipe water damage stop the supply of water.

What is the price 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 following breakdown of pricing for each square foot:

Will Water Damage Be Covered by the homeowner’s insurance policy?

If the cause of the damage was unintentional and sudden homeowners insurance policies typically cover the damage. According to the Insurance Information Institute, homeowners insurance may cover repair or replacement for a damaged window, however, not if the damage was the result of neglect.

Neglect can be described as damage to a surface or object that is caused by exposure, poor maintenance or general degradation. According to the US-based Insurance Information Institute, homeowners insurance does not cover damage due to neglect.

If the water damage resulted from an event that is a flood, it will not be covered under the homeowners insurance. Rather, a flood policy would be mandatory. Mortgage lenders might need flood policies in certain regions. Flooding can be caused by storms, flooding ground, overflowing bodies of water or the overflowing or surge of bodies such as streams, lakes, rivers and oceans.
