Flooding damage repair – Napa

Homeowners in Napa get hit with flood damage regularly. Whether you’ve been affected by a natural disaster or a localized catastrophe such as a fire suppression activation, Critical Control is standing by to respond 24/7.

Water damage is more common when water gets into a structure or home by way of a flood, storm or ruptured pipe. Sometimes the damage is apparent and evident. Sometimes, the damage is hidden or not reported.

Water damage remediation is much more complex than just drying the interior. Modern techniques for water damage repair like Critical Control, can often reduce damage that would normally need a total structural replacement.

Water Damage Restoration Guidelines Exist so call a Professional

Many times, building or home owners try to tackle water damage with DIY solutions found on the internet. This is not advisable. Water damage can be controlled by following established guidelines. These guidelines demand the expertise and equipment of professionals. The guidelines can be available in the IICRC Standard Reference Guide, or Professional Water Damage Restoration book. This guide exists because of the necessity for professional standards in cases involving water destruction to buildings and homes and the dangers they can create.

The IICRC guidelines assist restoration experts like Critical Control to evaluate the kind and severity of the damages on every project.

There are really important reasons why water damage experts need to follow these guidelines. In certain situations, an Indoor Environmental Professional (IEP) is necessary. An IEP is a professional who has the knowledge and experience to evaluate a site for contamination, collect samples, get lab tests, and then advise us on the category of water damage.

This is especially important when the building’s residents are at high risk or are concerned regarding contamination.

Water damages caused by categories and classes


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

The class refers to how dirty the water that entered the structure is. The first category is water that comes from a clean source such as the sink or tub, or a water source that bursts.

Category 2 water is characterized by high levels of contaminants and can cause illness if it is inhaled or touched. This can include sources which might not appear to be dangers, such as the discharges from washing machines, or overflows from toilets.

The water in Category 3 is highly polluted, meaning it could contain pathogenic, toxic, or other harmful agents within it. Most often, this is due to contamination by sewage, toilet backflows after the toilet trap and seawater, flooding from rivers and streams or any other water flowing from the building exterior. This water can be contaminated by pesticides, heavy metals or harmful substances.


The IICRC has also developed classes we use in measuring the amount of water intrusion into your property. This is basically an outline of the amount of water a building or house is.

Class 1 means the least amount of water and absorption. This is the case when water comes in contact with less than 5% the building substances which absorb water. This is because most materials that are affected by water do not absorb or hold water. Examples are concrete, finished/coated wood, plaster or masonry.

Class 2 signifies that there is significant 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 concrete, wood, or bricks and mortar.

The porous materials, such as carpet, insulation , and fiberboard that comprise Class 3 comprise around 40 percent of wall, floor and ceiling materials. This includes about 40% in class 3. and also where other materials that do not take in a lot of water, such as concrete or plaster haven’t been negatively affected.

Class 4 means that water has become deeply stuck in materials that do not easily absorb water like wood, plaster, concrete and bricks and mortar. This will require more time to dry and special drying techniques.

How to Dry a Water Damaged Building or Home Building Works


Three methods for removing water from buildings are physical extraction, dehumidification and the process of evaporation. Removal of liquid water is at about 500 times more efficient than merely putting up with dehumidifiers and air mover. The quicker the structure can dry more efficiently. The amount of stuff that needs to be extracted will affect the extraction process as well as dehumidification methods.

Water damage professionals use various extraction methods. Our tools include wands, subsurface extraction tools, self-propelled tools, and vacuum squeegees.

Forced Evaporation

The remaining moisture is then dried with high-velocity air movers after the maximum amount of water is removed.

When an object gets wet or submerged in water it absorbs a portion of the water or moisture. The material becomes damp or wet due to this.

Saturation is the time where it becomes unachievable for the air to contain any moisture. Higher humidity means that the air is more close to saturation.

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

This signifies that the object no longer absorbs water from the air. We call that saturation point the point of evaporation. Once saturation is attained the drying process commences.

High-efficiency air movers dry objects on two sides during the evaporation phase. They generate strong airflow that is directed by a filter system.

An air mover moves around 10 to 20 times the amount of air than a fan , or an ordinary household fan.

The object is dried by airmovers about 10 times faster that in natural conditions in which no air mover was used.

High-velocity airflow removes the moisture from the surface and absorbs moisture that is drawn out by air movement.

Utilizing Heat To Aid In the Drying Process

Heat is an important component of any restoration project. To dry out materials damaged by water, we make use of various kinds of heaters.

Electric Heating Equipment: These heaters can be used to dry jobs which require multiple sources of heat. You can run multiple heaters simultaneously because of their numerous power ratings.

You can also reduce or off electric heat as the work is completed, but without impacting other heaters. This means that you can lower one heater, while increasing the wattage of another to maximize efficiency and reduce your cost of energy.

Electric heaters are a common feature in restoration jobs since they generate virtually no emissions and use very little water. The only downside is they take longer to heat up, requiring longer drying time. process in general.

Hydronic Bioler (TES) Hydronic Bioler (TES) The boilers quickly heat up and emit very little emissions. They can be run on propane or natural gas.

Hydronic boilers are different from electric heating in the sense that they don’t use forced-air to distribute heat, which means it could be difficult to evenly heat an area using these kinds of heaters. They also operate at a lower temperature, making them ideal for drying jobs that require walls and ceilings to be left unattended.

Hydronic boilers are often employed when there isn’t enough electricity to run electric heaters. They can generate radiant heat and can keep your drying space warm without the requirement of an electrical source.


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

The LGR Home Dehumidifier can remove 170 pints of water from a damp structure which has been badly affected by water damage each 24 hours.

The home dehumidifier can extract water from the air the same way it does an LGR Refrigerant Dehumidifier. It will also remove up to 99 percent of airborne mold spores through the elimination of condensation.

Repairing Hardwood Floor Water Damage

It is crucial to get rid of flooring that has been damaged by water to ensure that repairs can be done by removing the subflooring.

The subflooring has to be removed and repaired prior to. Then the affected hardwood boards must be sanded or replaced. In order to ensure a uniform appearance flooring, all floors should be sanded and repaired after these repairs have been made.

Carpets are prone to water damage

Floods can cause significant damages to your house and make it costly and difficult to repair. You might need to change your flooring, even if you have removed the water from the area as soon as possible.

After spending time and money restoring your home to its pre-flood condition, it would be devastating to find that the finished results leave something to be desired.

In this regard, it is important to assess the extent of damage as quickly as is possible. First thing to do is to determine if the damaged part requires replacement. It is possible to wash the carpet and then use it again after drying. This can alleviate any worries about the growth of mildew or persistent smells.

Salvaging Carpet After a Water Damage Event

If the damage from water is very extensive It is likely that you’ll notice stains on your carpeting. In certain instances, the only way to get rid of these stains is to replace the flooring. A strong, lingering odor can also be an indication to replace your carpeting. You will need to replace your carpet padding and padding when this happens.

The next step in determining whether or not you’ll need to replace your carpet is to find out if the floor can be dried and cleaned professionally. If you can have a reputable company perform the cleaning, you’ll be able to determine how severe the water damage was. We can assess whether your carpet needs to be replaced or saved. Be aware that certain methods used for drying can also further damage the carpet if it is already in poor condition.

The main factors that determine whether or whether the padding and carpet need to be replaced are:

Are your carpets professionally dried, cleaned, and cleaned?

If the padding under your carpet is damaged, it can impact the time that your carpet is clean. Although your carpet might have dried quickly but the chance of mildew growth is still there if the padding underneath it has not dried as well.

A professional carpet cleaning company is the most effective way to make sure your carpeting is clean and dry after the flood. Once the cleaning is complete then you’ll have the ability to make an informed decision on the state of your carpeting. You’ll also be able to determine whether to replace it.

Drywall that has been damaged by water

The severity of the damage will determine the nature and method of drywall repair. Repairing water damage could be as easy as removing the drywall portion and cleaning the area and then putting it back.

The other side is that major damage could need to be repaired completely, including the wall studs and fiberglass insulation.

The drywall that is damaged by water usually harbors mold spores which can not be easily removed. In most cases, the drywall will have to be replaced. We utilize moisture testing tools that help us determine how large and where the moisture has become. This allows us to identify areas that are damaged and limit costs to only the areas that are damaged.

The water can also cause structural damage by causing the wood to expand and expand and contract. It is much easier to break wood when it is moistened by water. If the water sits for a prolonged time, it could cause a significant amount of rot in the wood which can cause it to crack easily.


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

Foundation Water Damage

There are numerous reasons why water damage can cause to the foundation of a home. Although not all water problems could cause structural damage, it is important to correct foundational issues as quickly as is possible to avoid future structural damage.

The water damage from foundations can lead to many different problems based on how it is dealt with. It can lead to serious structural damage if the issue isn’t treated quickly.


Roof Water Damage

Similar to foundation water damage roof water damage is fairly common after natural catastrophes. In addition to the possibility of roof leaks, roof damage can cause problems with the walls or the foundation of a house or building.

Roof leaks are expensive and have serious disadvantages. A leak in the roof may cause mold and mildew to develop, which could be deadly. Leaks in the roof may also cause damages to the roof truss.

Leaks from the ceiling could cause your rafters to deteriorate and become soft if you don’t take action immediately. Roof water damage can also result from electrical issues which could lead to an electric fire. These are all good reasons to have roof water damage repaired swiftly after a flood or any other damage that is unexpected.

HVAC Water Damage

Your home may be damaged structurally if your HVAC system is not working properly or the wrong equipment is put in place. Without HVAC, you are opening the interior of your business or home to all sorts of issues. The growth of mold can cause serious health issues.

Pipe water damage

If you have pipe water damage, it is most likely coming from a pipe that has burst in your home. Once you have determined that there has been a leak, it’s important to seek out professional assistance to stop the leak and ensure it doesn’t cause structural damage.

A ruptured pipe can result in serious damage. When pipes are damaged and water enters your home, causing severe damages and necessitating water damage repair – an event that could bring with it structural damages.

Stop the water supply, and then contact an expert IICRC-certified specialist with a firm for water restoration such as Critical Control as soon as you detect damaged water pipes.

What is the cost to repair the water damage?

Water damage restoration cost per square foot

Repair and cleanup costs can vary based on how much square footage you own. The following pricing breakdown is available from National Flood Services for each square foot

Does water damage get covered by homeowner’s insurance?

Homeowners insurance policies are usually used if the damage is sudden and accidental. The Insurance Information Institute states that homeowners insurance will be used to pay for repairs or replacement of broken windows, but not for damage caused by neglect.

Damage from neglect may be described as wear and tear of an object or surface because of exposure, insufficient regular maintenance or general wear and tear. The Insurance Information Institute in the USA states that homeowners insurance will NOT cover neglect-related damage.

If the water damage resulted from flooding, the incident will not be covered under the homeowners insurance. Instead, a flood insurance policy is necessary. In certain areas, flood policies are required by mortgage companies. Flooding can occur due to flooding, over-saturated ground, overflowing or surging bodies of water like lakes, rivers, ponds rivers, oceans, and streams together with high winds.
