Category 3 Water - Known as "black water" and is grossly unsanitary. This water contains unsanitary agents, harmful bacteria and fungi, causing severe discomfort or sickness. Type 3 category are contaminated water sources that affect the indoor environment. This category includes water sources from sewage, seawater, rising water from rivers or streams, ground surface water or standing water. Category 2 Water or Grey Water that is not promptly removed from the structure and or have remained stagnant may be re classified as Category 3 Water. Toilet back flows that originates from beyond the toilet trap is considered black water contamination regardless of visible content or color.[6]
Position the drywall section in the opening, and use a helper to hold the new drywall in place. Install fasteners through the drywall into the wall or ceiling framing. You can use drywall nails or drywall screws. Screws are better because they cause much less damage to the internal structure of the drywall sheet during installation. Install fasteners every 9 inches on the perimeter, and every 12 inches in the field. If necessary, use a piece of plywood or one-by lumber for a backing and fastening surface behind any drywall edges that don't fall over framing.
When a disaster of this magnitude occurs, the first things a plant will need are lighting and pumps. This requires the use of on-site generators and temporary power connections. It's highly recommended to not allow the plant distribution system to be back-fed. If a motor is required to turn a pump, a portable motor starter fed by the generator should be installed on a temporary panel next to the motor.
After a mold has been cleaned, repaired, changed over, and final-checked, it needs to be given a new status and moved to one of three areas—typically racked in holding/storage area, reset in the press, or staged as a back-up mold in a molding-cell operation. It could also go to an outside vender for rebuild or production. You should know where your molds are.

When the next water damage call comes in for a flood cleanup due to a broken water pipe or drain backup, make sure you have all the commercial restoration equipment on hand that you need to tackle the job in a moment’s notice. Events like floods, hurricanes, wildfires and other natural disasters can leave homes and businesses in peril and in need of professional restoration services.


The European-American community was founded by David Hill, Isaiah Kelsey, and Richard Williams, who arrived in the Tualatin Valley in 1841, followed by six more pioneers in 1842. The locality went by two other names—East Tualatin Plains and Columbia—before it was named “Hillsborough” in February 1850 in honor of Hill, when he sold part of his land claim to the county.
Sewage back‐ups, pipe leaks and breaks not only cause sewage damage, but result in dangerous conditions that require meticulous cleanup to ensure a return to a safe environment. That’s why WaterBear leads in industry standard guidelines and takes every precaution to contain contamination within exposed areas, then thoroughly cleans and decontaminates them. We work to return the areas to their original state – fresh, clean and safe.
Many parts of a car are challenging to clean and dry because they are hard to access. Door locks, window regulators, power seat motors, heating and air conditioning components, and many small parts are tucked away in enclosed areas or up under the dash. These items may work okay immediately following a flood, only to fail later due to contamination by dirty water.

Our water damage technicians first determine the cause of flooding in your home before beginning the process of draining, cleaning, and restoring. The water damage cause plays a vital role in the water damage process. When flooding is caused by natural calamities, there’s a higher chance of bacteria buildup in the affected areas and calls for immediate disinfection. Other water damage causes do not pose health threats and require only the basic process of restoration.
There are also several 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.
In mold repair, structure is especially critical when working with many pieces of close-fitting tooling that are nested into plates. Remembering the type, fit, relational position of components, and the sheer volume of tooling in some molds can be overwhelming enough without adding confusion about where you are in the process of the repair. In shops where two repair techs are usually assigned to a mold, time can be saved by working in a organized approach.
Keep the basement dry as it's the most common place to find damage. Flooding, burst pipes, and even clogged gutters can cause leaks. Pitching the landscape, cleaning the gutters, and installing downspout extensions are simple outdoor fixes. From the inside, install a sump pump and water alarm. Have the basement inspected for waterproofing – or have some installed.
Cut through the paper facing of the drywall sheet with a razor knife. Cut along the drawn lines. Break the drywall along the face cut, and fold the drywall slightly to make a crease in the paper backing of the drywall sheet. Cut through the crease in the backing paper with a razor knife from the backside of the drywall sheet, and remove the unwanted portion of drywall. To make cuts that are perpendicular to each other, use a keyhole saw for the shorter of the two cuts, and then fold and cut the drywall.
No need to take a wrecking ball to the entire house at the sight of a little mold.  You can keep the price down by focusing just on the area where there is visible mold.  For example, mold on drywall in one corner of the room only needs cut out and replaced in that corner.  Yes, the rest of the room (and maybe adjoining rooms) should be cleaned, but only damaged drywall needs to be cut out and replaced.

Locate and repair the source of the leak. The source of the problem is usually apparent once you remove the drywall and expose the framing. If the leak source is not easily determined, consult a licensed contractor before you replace the drywall. You must repair the cause of the leak or mold and mildew will eventually reform over the new drywall. An unresolved leak may also create additional damage to framing, insulation, siding and flooring.

Even if the water in your home is clear, it could be contaminated by sewage or household chemicals. Ramirez recommends wearing waders, hip- or waist-high waterproof boots. In addition, wear rubber gloves to remove water-damaged possessions and to avoid contaminants, Ramirez notes. Be sure to throw out any food that may have come into contact with flood waters. FEMA recommends boiling water until authorities declare the water supply is safe.
Damage from long standing water falls in this class, like river flooding or storm surges from a hurricane. It has saturated materials such as stone, brick, and hardwood. These materials have low permeance — meaning they do not soak up liquids quickly. Time is the primary factor in this category. With a higher cost of cleanup and repair, it is important to get problems diagnosed and solved as quickly as possible.
You have to open up the wall to get at the mold growing inside. Since you have to repair the wall anyway, don’t hesitate to cut the drywall back beyond the obvious damage to find all the mold and let the wall dry out. To avoid cutting electrical wires, poke a hole through the damaged section and locate the wires first. Turn off the power to the outlets before you cut. Mist the moldy drywall and insulation with the pump sprayer to avoid spreading mold spores. Double-bag moldy material in heavy-duty plastic bags and tie them shut.
Category 2 Water - Refers to a source of water that contains a significant degree of chemical, biological or physical contaminants and causes discomfort or sickness when consumed or even exposed to. Known as "grey water". This type carries microorganisms and nutrients of micro-organisms. Examples are toilet bowls with urine (no feces), sump pump failures, seepage due to hydrostatic failure and water discharge from dishwashers or washing machines.
