Minnesota Water Damage Restoration

Water Damage Restoration MN If there was a flood or major pinhole leak  or broken water pipe in your home, it is likely that in addition to the water damage to the floors, the walls have been affected, too. There are instances when the water damage to the walls is apparent but oftentimes, the damage is unseen and cannot be easily detected by the average homeowner. If the flood or leak entered a room from the ground level, the floor including the carpeting, if there is any, will be covered by water which will then start to create vertical wicking in the walls. The degree of this reaction will rely on several factors such as the amount of water and how high the water level reached on the wall as well as the wall construction. Drywall is very absorbent because its core is made of gypsum and both of its sides are made of a type of paper similar to a cardboard. Because of its porosity, you can expect water to wick up on a drywall to more than two feet.  Both sides of the drywall will be wet but the inside part will contain more water for the simple reason that water would not quickly evaporate from that side. Very often, signs of moisture from the inside of the wall are not visible. For a professional trained in water damage restoration, the process of restoring wet walls starts with finding out how badly the walls are damaged. There is a wide range of professional metering devices that can be used by a restoration expert to help assess water damage. Noninvasive devices are among those widely-used by experts such as a moisture meter that checks for moisture in the wall using radio waves and an infrared (IR) imaging camera that also detects moisture since a damp wall would be cooler than a dry wall. These devices are noninvasive because there is no need to create holes or do anything with the wall material. A professional water damage restoration contractor will select the structural drying equipment in a scientific method based on materials, size of the water damage area, and the class and category of the water damage.  After the restoration expert has identified which walls have been water damaged, the drying process will begin aided by several types drying equipment. If the wall has no insulation, drying can be done without having to remove the baseboard or making holes in the wall. The restoration expert will use equipment called air movers to remove the molecules of water from the wall surface and allow the water to evaporate quickly. An air mover will be positioned along the wet wall for, approximately, every ten linear feet. During this process, more water is drawn to the surface of the wall as moisture evaporates from that particular surface. Another important and state-of-the art device used by water damage restoration professionals is a dehumidifier, which is installed to reduce the level of humidity in the walls and help stop the formation of mold. More than one dehumidifier may be used as necessary. A special drying system for the inner walls can also be used if the restoration expert sees it appropriate. This system involves directing air to enter the wall cavity above the sill plate by creating holes in this area. According to studies, this is the quickest and most effective way of drying water-damaged walls. In some instances, the inside or outside wall has some material or coating over it that acts like a barrier that restricts the movement of moisture in the...
