Category3 water damage from flood Category3 water damage in flooded home

A water intrusion where the water is grossly contaminated is referred to in the water mitigation and restoration industry as a Category 3 water intrusion.  Highly contaminated water is extremely unsanitary, carries pathogens which are disease causing.  Another term for Category 3 water is black water.  A Category 3 water intrusion can originate from a toilet discharge that originates beyond the toilet trap.    This is known as sewage and originates from the septic system.  Another lesser known Category water intrusion can come from the surface of ground water that intrudes inside a building.  This type of water is mostly seen in flood waters, but can occur from a large rain or thunderstorm where water intrudes inside the structure. 

 Due to the health effects of a Category 3 water intrusion, restorers must wear appropriate proper protective equipment to protect themselves from the health effects associated with mitigating this type of water intrusion.  Safety is not only important for the restorer but also for the occupants of the building.  People with compromised immune systems, young children and the elderly are at higher risk to suffering health related effects by coming in contact with Category 3 water.

In order to properly mitigate a category 3 water intrusion all porous materials must be removed which includes, carpet, underlayment or pad, drywall, and insulation.  Proper cleaning solutions that kill microorganisms and pathogens must be used to sanitize the surface of all nonporous materials.  Category 3 water intrusions are not to be taken lightly and should be reserved for professionals.

A supply line ruptures on a toilet and affects the bathroom, the adjoining room, hallway, and another bedroom.   SERVPRO is called to remediate the damage.  The homeowner, having never experienced a water damage situation, is shocked that so much equipment is placed in the home to dry the structure.  The burning question, the elephant in the room, is does it really take that much equipment to dry the structure, or is SERVPRO attempting to escalate the bill?  The answer to that question is that it does take that much equipment, and there is science and a standard to validate each piece of equipment.

Homeowners can be assured that SERVPRO, in placing equipment to dry a home is not, and will not attempt to place more equipment in a home than is requiredSERVPRO follows the industry standards for drying established by the Institute of Inspection Cleaning and Restoration Certification (IICRC) in the industry standard known as the S500.   This standard is used by all certified water mitigation specialist.  The standard is based on a science of dry called psychrometrics.  The application of psychrometrics by industry professionals is to dry the structure as quickly as possible and prevent additional damage such as mold growth, delamination of carpet, cupping of hardwoods and numerous other secondary damages that can be caused by water absorption into materials.  The standard used for drying is used by all insurance companies and adjusters and must be followed by restorers doing work for their insured.  This is verified by way of a drying log.  SERVPRO uses a system called DryBook that tells crew chiefs and technicians exactly how much equipment to place in a given area based on the percentage of affected area in a room.   This assures that each job is done according to standard. 

SERVPRO makes that drying log available to not only the insurance adjuster but the homeowner as well.  SERVPRO is transparent in its process and desires to keep happy customers willing to pay.  Although water damage is traumatic and disruptive, SERVPRO will make it "Like it never even happened."

Clogged Gutters and Water Damage

Clogged Gutters Clogged Gutters and Water Damage

A painted seamless gutter on a house is aesthetically pleasing to eye and adds to a home’s curb appeal, but gutters serve a greater purpose than looks when it comes to protecting your home from water damage. 

Gutters are designed to transport rain water from the roof to the downspouts and away from the home.  A gutter system that becomes clogged with leaves and debris such twigs, and nuts can lead to significant damage to a home.  Most people don’t realize the large volume of rain water that is moved by the gutters.  Every square foot of the roof collects six gallons of water in 1 inch of rainfall.   1800 square feet of roof transports a staggering 10,800 gallons per inch of rain.  When the gutter becomes clogged the water can only flow over the sides, or back up behind the gutter, causing damage to the fascia and roof deck boards.  When these areas get wet it can lead to leaks, mold and long term wood rot.  

Water Damage due to clogged gutters is not limited to just rainwater, a clogged gutter can also lead to ice damning in the winter.  This is where the water in the gutter track freezes, and pushes the shingles up as it expands when it freezes.  When it melts the roof deck and or ceiling of the home becomes wet.  

To prevent water damage from clogged gutters it vital that the gutters be cleaned of debris.  Another solution is to have gutter guards or caps placed on the gutters to eliminate anything other than water from entering the gutter. 

If you are experiencing water damage due to a clogged gutter system, SERVPRO of South Durham and Orange County can help once the gutter system has been cleaned, by properly drying the structure and performing any necessary mold remediation.

Moisture Mapping, What is it and Why Does It Matter?

Moisture Mapping, what is it and why does it matter when you have a water damage emergency? In a water loss situation, it not just the water that is seen that can cause significant damage to a property and its contents, but also the unseen water, that is not visible to the naked eye that can cause serious damage. Moisture mapping is the detailed process to identify all areas of water migration, using specialty tools to detect the moisture content of building materials, so they can be dried properly.

Improper drying due to unseen and undetected water can cause mold as well as rot if the materials stay wet for an extended period of time. This is often most evident in a situation such as a bathroom or kitchen where a water damage occurs. A supply line to the toilet or a water line to an ice maker breaks and flows onto the tile or vinyl flooring. It is quickly detected by the homeowner. They are able to stop the water flow and proceed to get the water up with towels and a shop vacuum. Due to their lack of understanding the migration pattern of water and moisture mapping, they think the job is done. Within a few days or weeks they notice a musty smell or observe discoloration on the flooring. It is then they call for a mold assessment. During the initial water loss, moisture mapping was crucial to detect water that had migrated behind baseboards, under flooring, inside wall cavities, behind cabinet kick plates or had migrated into the crawl space. Water damage Restoration professionals use moisture meters, penetrating and non-penetrating to detect water migration into these areas. Then they are to use the proper equipment, according to industry standards to effectively dry the structure and prevent the secondary damage caused by improper drying.

My Carpet is Wet, Now What?

10/9/2020 (Permalink)

One of the primary building materials found in both residential and commercial buildings is carpet.  Carpet comes in many different styles from traditional cut-pile to Berber and commercial glue down.  In a water damaged environment carpet is one of the most common building materials restoration companies, like SERVPRO of South Durham and Orange County are faced with mitigating and restoring if possible.  Salvaging damaged carpeting is not a one-size fits all application, but varies based on category of water loss and current condition of carpet 

The water loss category as classified in the restoration industry is the determining factor denoting the amount of contamination in the water. 

  • Category 1 is clean water that may be found when an ice-maker line ruptures.  If the restoration process begins within hours of occurring the likelihood of salvaging the carpet is extremely high. 
  • Category 2 is a reference to gray water which has picked up some forms of contamination, for example water from the dishwashing machine or an overflow of washing machine. The soap, food particles and soil combined with the water make the water a Category 2 water loss.  Salvaging carpets under this condition is also extremely high, but the emergency service of drying must begin quickly to prevent the current category from progressing to a Category 3 and rendering it unsalvageable.
  • Category 3 water damage is denotes gross contamination and hazardous. This can be raw sewage or water damage that started as another category due to prolonged interaction with bacteria and other pathogens on the building materials that populate due to the increased moisture content.  Category 3 water damage is not considered salvageable in most cases.

An additional matter of consideration as to whether carpet is salvageable is its current condition.  Pre-existing conditions such as delamination, separating seams, fiber loss and frayed fibers are determining factors as to whether a carpet can be salvaged and restored. 

If you have experienced any type of water loss, mitigating the damage quickly is essential to prevent a bad situation from becoming worse.  Call SERVPRO of South Durham and orange County at (919)596-1242 and we will make it “Like it never even happened.”

Helpful Tips to Prevent Household Water Damage

9/28/2020 (Permalink)

Household water damage can be a very traumatic and costly experience that no one looks forward to experiencing.  However, outside of purchasing homeowner’s coverage very few people go any further to prevent potential water losses.  This is largely because most people rarely think about the potentiality of it occurring to them, thus they fail to plan.  The reality is that on average homeowners will experience one water loss during a twenty year time period.  Planning for prevention is a wise strategy to mitigate the impact of a water loss, if and when the time comes.  Here are some helpful, inexpensive and simple tips to employ to prevent or mitigate the impact of water damage to your home.

  • Check your water heater for rust and leaks. Make sure the water pan isn’t about to overflow.  If it is have it serviced.
  • Have your dishwater and HVAC unit serviced to make sure it is in proper working order.
  • Cut the water off at the washing machine when not in use.
  • Replace supply line hoses to the toilet every four to five years.
  • Turn water off at toilet supplies when leaving the home for extended periods of time.
  • Install a water monitoring sensor to the hot water tank.
  • Allow faucets to dip during freezing conditions to prevent the lines from freezing.
  • Keep the heat running even when away during freezing conditions.
  • Make sure pipes are properly insulated.
  • Have roof inspected for loose or missing shingles.
  • Cut water off to the whole house when leaving for vacation during spring, summer or fall. This can be done by purchasing a simple tool at your local hardware store and turning the main valve off at the street.
  • Purchase a moisture meter and check your walls and floors for excessive moisture periodically.

Although these tips are sound and easy ways to prevent or mitigate water damage, they are not guarantee that a loss won’t occur.  If you do experience a water loss and need help to mitigate the damage, call SERVPRO of South Durham and Orange County at (919) 596-1242.

Primary and Secondary Water Damage

8/24/2020 (Permalink)

A water intrusion can have immediate and long-term effects on building materials and contents such as furniture, electronics, art work, clothing and more.  The immediate effect that water has on materials is known as primary water damage, the long-term effect that water has on materials is referred to as secondary water damage.

Immediate, primary water damage is evident when a large volume of water comes through an upstairs floor and into the ceiling below.  The weight of the water which causes the ceiling to sag and the drywall tape to pull apart are examples of primary water damage.  Another example would be when water comes in contact with particle board which is used to make many types of furniture; the swelling of the particle board is immediate and irreversible.  Materials that are not made to encounter water and suffer immediate damage cause primary water damage.

Secondary water damage occurs over a period of time.  Excess humidity caused by a water intrusion and materials that are hygroscopic, or easily absorb water, are susceptible to secondary water damage.  Secondary water damage includes loss of structural integrity, dimensional changes and microbial growth.

Both primary and secondary water damage can be costly; however, the total impact and dollar value of the loss can be mitigated.  It is important to start the mitigation process immediately, which includes extraction of water, setting drying equipment and implementing controls to prevent secondary damage.  If you are experiencing a water damage emergency don’t delay – call SERVPRO of South Durham and Orange at 919-596-1242 any time, day or night.

Oh No! Water Damage and My Hardwood Floor

5/22/2020 (Permalink)

One of the most common calls our franchise receives is from customers in distress over a water loss event impacting their hardwood flooring.  The #1 question they have is, “Can my floors be saved?”  It is a well-known fact that water causes significant damage to hardwood flooring.  Wood is hydroscopic, meaning it absorbs moisture from the air, and is subject to catastrophic damage if not dried quickly.  Our customers have every right to be concerned, but the answer to the question as to whether the floors are salvageable is not a yes or no response, but depends on numerous variables that must be accessed by our ICRC certified technicians.  These include:

  • Category of water loss
  • Class of water loss
  • Amount of time flooring has been wet
  • Type of hardwoods

Category of water loss simply defined relates to amount of contaminates in the water.  A Category 1 water loss is indicative of clean water from a burst pipe.  A Category 2 water loss contains significant levels of contaminates, such as an overflowed washing machine or dishwasher.  A Category 3 water loss contains gross levels of contaminations including harmful pathogens and toxins and could be the result of sewage or a toilet back flow.  A Category 1 water loss is the most likely category for hardwoods to be saved because the water is clean.  A Category 3 water loss is not salvageable.  However the amount of water impacting the floors, which is indicative of the Class of water loss, has a significant bearing on how much absorption of water the floors will take in and has a direct correlation to flooring damage.

 There are 4 Classes of water loss. The greater the amount of water directly impacting the hardwoods the more likely it is for water to penetrate the joints and impact the sub floor.  Once water is trapped in the flooring joints it would requires specialty drying equipment, making it a Class 4 water loss.  SERVPRO of South Durham and Orange County has specialty drying systems to remove moisture trapped in the joints of hardwood flooring.

Time or Duration of Moisture is a huge factor in determining whether hardwood flooring can be saved.  It is imperative to respond immediately.  The longer the flooring stays in contact with the water the more damage it creates limiting the chances of saving the floors.  Hardwood flooring that is mitigated within the first 24 hours has the greatest chance of being salvaged.

The Type of Hardwood Flooring is a critical factor as to whether the flooring can be saved.   Real Hardwood flooring is made out of a single layer of wood, and is salvageable if mitigated in time and is not a Category 3.  Although water in the subterranean layer will cause the ends to bow upwards a condition called cupping, the floors can be sanded down and refinished.    Engineered hardwood flooring is made of multiple layers of wood going in different directions.  The veneer finish cannot be sanded and refinished.  Often when engineered floors are impacted with moisture the expansion of the wood will result in a cracked finish or the popping up of the wood because it expands in all directions.  With these conditions present, the engineered hardwood flooring cannot be saved. 

Regardless of whether the floors can be saved or have to removed, SERVPRO of South Durham and Orange County can help clients through the mitigation and the restoration process, making it "Like it never even happened."

Water Damage and Odor Control

5/21/2020 (Permalink)

One of the first things homeowners often notice in a water damage environment is the persistent, unbearable malodors.  There have been times where homeowners had a small water loss that they felt was unnecessary to call a restoration company to dry because they felt they could easily handle it themselves, until the manifestation of odors forced their hand.  The looming question is why does it seem that water damage and odors go hand in hand?

Moisture is one of the key components in odor creation as microorganisms, such, as mold, fungi, and pathogens and other bio-pollutants need it flourish.  In a water damaged environment the moisture creates a suitable environment for them to multiply.  The organic materials, such as wood, drywall and carpet backing found in homes are the food source these organisms thrive on.  They are already present in most home environments, but at very low levels; because without moisture they are unable to survive.  This is one of the reasons why proper drying to the IICRCS500 standard is necessary for each water damaged environment.  When water is trapped under flooring, behind baseboards, wall cavities, and behind toe kicks of cabinets and is not properly dried it creates the conditions for exacerbated microbial growth and the mycotoxins they release are the odors that are smelt.  These malodors are a warning of danger and it is a well-known fact that water damaged environments can pose serious health risks if not properly mitigated.  The number 1 reason for residual malodors in a water damaged environment is improper drying.

The solution to odor elimination is to remove the source of the odor and this is not done by spraying air freshener and masking the odor.  The well trained water restoration specialists of SERVPRO of South Durham and Orange County will not only treat the odor, but will leave you with the peace of mind that your home or business has been returned to a condition 1 , level of dryness, which is the drying goal of the industry standard aforementioned.  SERVPRO of South Durham and Orange County will make it "Like it never even happened."

The Dynamic Duo of Air Movers and Dehumidifiers

5/8/2020 (Permalink)

green air mover and green dehumidifier Our signature green air mover and dehumidifier at work.

Like the superhero Batman, who was armed with a utility belt with gadgets to fight crime, every SERVPRO crew chief and technician is armed with a formidable arsenal of air movers, dehumidifiers and the science behind them, to thwart the perils associated with water damage.  The science of water damage mitigation is called psychometrics. 

  • Psychometrics is the scientific relationship between temperature, humidity and air flow.

Understanding the aforementioned relationships allows the SERVPRO team to dry materials quicker and more thoroughly.

When materials such as flooring, walls and ceilings are wet the SERVPRO crew will extract any standing water because the most effective means of drying is removal of the water.  Once the standing water is extracted and areas where trapped water could be located have been opened, the dynamic duo of air movers and dehumidifiers comes into play.

The Air Mover is engineered to create high volume air flow across a wet surface increasing the rate of evaporation which is the process of turning a liquid into a gas.  The air mover alone is not enough, in order to be most effective, adequate temperature and proper dehumidification are required.  The higher the temperature the more moisture molecules the air can hold.  This accelerates evaporation. 

The Dehumidifier is a piece of drying equipment that pulls the moisture created by evaporation out of the air and collects it so it cannot re-evaporate.  Dehumidification also lowers vapor pressure and reduces the relative humidity which allows the wet materials to dry quicker.  Vapor pressure is the force exerted by water vapor (humidity) in the environment.  The area with the greatest amount of moisture will have the highest vapor pressure and it will seek equilibrium or balance.  The danger with this is that moisture created due to water damage in one area will spread and cause secondary damage in adjoining areas if not mitigated properly. 

The SERVPRO team uses the science of psychometrics along with the dynamic duo of air movers and dehumidification to quickly and effectively dry your structure and get you on the road to recovery; making it “Like it never even happened.”

Categories and Classes of Water Damage

3/10/2020 (Permalink)

Not everyone knows that water damage has different categories and classes, and just because it is a low category doesn't mean that is is a low class.

Categories of Water Damage

Assessing the severity of the damage is important for determining what is needed to start the water loss repair and mitigation. 

Category 1 - clean water, or water that does not pose a threat to humans. Possible causes of this type of damage include broken appliances or sink overflows. 

Category 2 - gray water, this means that the water is contaminated and may cause sickness if ingested. This type of water contains microorganisms. Broken toilets, broken sump pumps and seepage may cause category 2 water damage. 

Category 3 - black water, this type of water is unsanitary, as it contains bacteria and other organisms that cause sickness. The possible sources of black water damage include sewage problems and contamination of standing water. 

Classes of Water Damage

The class of damage is important when assessing water damage repair options.

Class 1 is the least harmful form of damage. Materials absorb very little of the water from this type of damage. Water damage repair is the easiest in this type of situation.

Class 2 has a fast rate of evaporation, which means that carpets and cushions may be damaged. Water damage repair is more difficult when it involves class 2 damage. 

Class 3 has the fastest rate of evaporation. In this case, the water may come from broken sprinklers or other overhead sources, soaking the walls and furniture. 

Class 4 requires special water restoration and water removal procedures. This type of damage may affect hardwood floors, plaster and concrete.
