Mold Identification, remediation and removal
Molds could be found almost everywhere; they can grow on just about any organic material, as long as moisture and oxygen are present. There are molds that may grow on wood, paper, carpet, foods, and insulating material. It is impossible to get rid of all mold and mold spores in the indoor environment. Nevertheless, mold growth can be controlled indoors by controlling moisture indoors. It is critical to get advice from a mold removal specialist if you have any doubt about mold in your home as it can cause severe breathing problems for the inhabitants.
Molds reproduce by making spores that usually can’t be seen without magnification. Mold spores waft through the indoor and outdoor air continually. When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they’re growing on to be able to survive. Molds gradually destroy the things they grow on.
Many kinds of molds exist. All molds have the potential to cause health effects. Molds can produce allergens that may trigger allergies or even asthma attacks in people allergic to mold. Others are known to produce potent toxins or irritants. Possible health concerns are an essential reason to stop mold growth and to remediate/clean up any existing indoor mold growth.
Since mold requires water to grow, it is necessary to stop moisture problems in buildings. Moisture problems can have many causes, including uncontrolled humidity. Some moisture problems in buildings are linked to changes in building construction practices during the 1970s, 80s, and 90s. A few of these changes have resulted in buildings which are tightly sealed, but might lack adequate ventilation, possibly leading to moisture build-up. Building materials, including drywall, may not permit moisture to escape easily. Delayed maintenance or inadequate maintenance are also connected with moisture problems in schools and large buildings. Moisture problems in portable classrooms and other temporary structures have often been related to mold problems.
When mold growth occurs in buildings, adverse health problems might be reported by some building occupants, particularly those with allergies or respiratory problems. Remediators should avoid exposing themselves and others to mold-laden dusts as they run their cleaning actions. Care ought to be used to stop mold and mold spores from being dispersed through the air at the place where they can be inhaled by building occupants.
Sometimes, indoor mold growth might not be noticeable. It is possible that mold could be growing on concealed surfaces, such as the rear side of dry wall, wallpaper, or paneling, the very top of ceiling tiles, the underside of carpets and pads, etc. Potential locations of hidden mold can include conduit chases and utility tunnels (with leaking or condensing pipes), walls behind furniture (where condensation forms), condensate drain pans inside air handling units, porous thermal or acoustic liners inside ductwork, or roof materials above ceiling tiles (due to roof leaks or insufficient insulation).
Hidden Mold Growth
Some building materials, including dry wall with vinyl wallpaper over it or wood paneling, may act as vapor barriers,(5) trapping moisture underneath their surfaces and therefore providing a damp environment where mold can grow. You may suspect hidden mold if a building smells moldy, but you cannot see the source, or should you understand there’s been water damage and building occupants are reporting health problems. Investigating hidden mold problems may be challenging and will require caution when the investigation involves disturbing potential sites of mold growthmake sure to use personal protective equipment (PPE). As an example, removal of wallpaper can lead to a massive release of spores from mold growing on the bottom of the paper. In case you believe that you could have a hidden mold problem, you might want to consider hiring an experienced professional. If you find concealed mold, you should revise your remediation plan to account for the total area impacted by mold growth.
Mold Prevention Tips
- Repair leaky plumbing and leaks in the building envelope as soon as possible.
- Look for condensation and wet areas.
- Keep moisture due to condensation by increasing surface temperature or reducing the moisture level in air (humidity). To increase surface temperature, insulate or increase air circulation.
- Vent moisture-generating appliances, for example dryers, to the exterior where possible.
- Perform regular building/HVAC inspections and maintenance as scheduled.
- Clean and dry wet or damp spots within 48 hours.
- Do not let foundations stay wet. Provide drainage and slope the ground away from the base.
