Water damage can be categorized into two categories: superficial and extensive water loss. Water damage can also be categorized as total loss of utilities due to water intrusion. Water damage in the form of subsurface water is a comparatively rare phenomenon. It may be due to overflowing pipes, overflowing storm drainage systems, clogged drainage fields, overflowing septic tanks, malfunctioning of washing machines, and leaking taps. There are different types of water damage that are categorized under superficial damage and extensive damage.

Water damage restoration refers to different possible damages caused by water encroaching on an area where it can enable penetration of an object or system by damaging processes like rotting of wooden furniture, mold growth, corrosion of metal, growth of bacteria, shrinking of composite materials like plywood, cracking of wood, de-lamination of metals like iron, rusting of metals like copper, corrosion of plumbing pipes, and swelling of water-logged carpeting. Water infiltration can also cause damage to the surrounding property. It can cause damage to the building envelope, wall or flooring materials, electrical equipment, machinery, furniture, health and safety appliances, decontamination of rooms, loss of production, and so on. The costs associated with water infiltration can be categorized as direct costs resulting from flooding, indirect costs resulting from the delay in repair of contaminated building materials, lost time for cleaning and deodorizing, disruption of normal business operations, and the cost of replacement of damaged goods.

The water damaged restoration can be done for both residential and commercial establishments. However, the process can be more complicated for residential buildings, as the property is subjected to more risks of flooding and more changes are usually required in the restructuring of the building. Water damage restoration can also be complicated for commercial establishments. For instance, damages caused by flooding can compromise the structural integrity of the establishment due to wet conditions. For this reason, it is important for owners of commercial properties to take extra precautions in order to prevent water ingress.

Before the water damage restoration process starts, the area that needs to be treated should be declared safe and secure by the professional service. This is necessary to reduce risks of contaminating other areas which could lead to further problems. Once the previous state of the structure has been declared secure, the next step of the process should start with the clean-up. Every step of the water removal process is an essential procedure that cannot be left for the last moment. It should be completed in order to make sure that the contaminated area will not pose any danger to the people living nearby or to the building itself.

A good water damage restoration service should always take care of the most obvious damages such as holes, cracks, and leaking pipes. It should also take care of the smaller, yet significant water-related damages like deformation of building materials caused by moisture, pests growth and formation of molds, and so on. For leaks, they must immediately seek a solution and fix it. In case of molds, they must prevent the development of more molds in the area and seal and eliminate any open or damp spots where they might grow.

However, there are some cases where water damage restoration is more complicated than what can be seen on the surface. For example, a burst pipe or sewage backup poses great risk to the environment and can cause serious damage to property, particularly to houses located below the ground level. If left unchecked, a burst pipe may cause serious damage to the surrounding structures. Sewage backup is also a major issue when it comes to water damage restoration. Aside from the risk of causing structural damage to buildings and houses, a sewage backup poses a bigger threat to the public health because of the volatile ingredients that come with its waste product, known as feces. Therefore, in order to prevent any issues arising out of sewage issues, it is best to call a water mitigation company.
