Inhaling spores and parts of mold can cause health problems for people with compromised immune systems. For that reason, porous items and materials affected by mold should usually be discarded, not cleaned.
A few days before Los Angeles Mold Remediation arrives, move as much unaffected furniture and other items as possible. And clear a wide access area around the moldy areas. The first step is to spray the mold area with biocide.
Molds grow in wet or damp areas, and they thrive in moist and warm conditions. Hence, you need to avoid these areas in your home or office. Regularly check and fix any leaking taps, faulty plumbing, or water damage in your building to prevent mold growth. Molds produce allergens, irritants, and some toxic substances that can harm your health and lead to life-threatening diseases if you inhale them. You should wear personal protective equipment (PPE) such as a mask, gloves, eye protection and face shield when dealing with moldy materials or cleaning them up to minimize exposure and ensure that you do not spread the mold spores around the building.
PPE must be worn at all times if you are handling or removing the moldy material in a small or large scale. The minimal type of breathing mask that you can use to protect yourself from mold spores is an N-95 particulate respirator approved by the National Institute for Occupational Safety and Health (NIOSH). It is also advisable to wear clothing that you can launder or discarded after the project is completed and to open windows during cleaning, as this will help to ventilate the space.
You should also regularly clean and dry items that collect moisture, such as curtains, rugs and mats. You can use mold-inhibiting detergents or cleaners to do so. You should also vent appliances that produce moisture such as clothes dryers and stoves to the outside of your building, so that humidity levels remain low.
The most important factor in preventing mold growth is regular inspection and repairs of any leaks or water damage in your building. Ideally, you should inspect your building on a weekly basis and fix any problems immediately. Molds can easily recur once they are exposed to a wet environment again, so it is crucial that you take action immediately to prevent this from happening.
You can monitor the ambient temperature and humidity in your home or office with a hygrometer. Try to keep the relative humidity at about 30 to 50 percent to inhibit mold growth. You can also improve air circulation by opening windows, using fans, and running an exhaust fan in your bathroom and kitchen. You should also store any items that can accumulate moisture in well-ventilated storage areas.
While surface molds can be removed easily with a scrub brush, store-bought bleach cleaner and rubber gloves, if you’re going to do a serious job of cleaning up your property you need to take more precautionary steps. Regardless of whether you’re working on a small area or large remediation project, wear personal protective equipment (PPE): a disposable paper mask, head covering and foot covering. During a medium or large remediation project, PPE should consist of a full body suit made of a breathable material such as TYVEK. The suits should also have a seal around the ankles and wrists to prevent the escape of dust and mold spores into the room.
Next, you’ll need to set up fans and dehumidifiers to dry the affected areas and make sure the moisture level is below a certain threshold. If this isn’t done, mold spores will simply grow back, and your remediation will be in vain.
Once the area is completely dry, it’s important to remove and dispose of all porous building materials, including drywall, insulation and carpeting. It’s a good idea to contact a hazardous waste company for large amounts of these materials. If the mold has grown in air ducts or wood framing, you’ll likely need to hire an asbestos abatement specialist to clean and disinfect them.
For non-porous surfaces, like tile, grout and glass, you can often wipe them down with a damp cloth to remove surface molds. For more stubborn growths, you may have to sand or scrape the area and then reapply a cleaning mixture. If you’re using a commercial cleaning product, be sure to follow all the manufacturer’s instructions for use and don’t mix ammonia with bleach; this can form poisonous gas.
Using PPE, you can then disinfect any surfaces that have been contaminated with a biocide and vacuum up any remaining mold particles with a HEPA (High-Efficiency Particulate Air) cleaner. After all of this, you can finally install new drywall and insulation, repaint the cleaned wall surfaces and reinstall all your belongings. However, the key to preventing future mold growth is addressing the moisture problem that caused the original mold outbreak in the first place: repairing leaks; correcting humidity levels; and sealing all gaps, cracks and crevices to prevent further moisture entry.
Mold spores thrive in moist conditions and can spread to areas that weren’t affected by the initial outbreak. The first step in a professional remediation process is to address any sources of moisture. Moisture can come from a leak in a roof, or even just from high humidity.
The next step in the process is to clear the area of the mold. This is done by enclosing the area of the mold and using fans to blow out any wet areas. This will help prevent the mold from returning.
Next, the contaminated area is cleaned using a biocide or fungicide solution. All surfaces, including walls, floors, and ceilings are treated with the solution. Non-porous materials, such as metals, can be lightly scrubbed to remove any visible mold growth. Porous building materials, such as drywall and carpeting, may need to be removed from the home and disposed of as required by local laws.
When treating mold, professionals wear a variety of safety gear, including rubber gloves, goggles, face masks with particle filters, and respirators. This is because the spores from mold can cause respiratory problems for those who are sensitive to them. It is also important to use a dusting method that minimizes the amount of spores in the air, and that contaminated surfaces are properly sealed when finished.
Once the area is disinfected, mold remediation companies use fans and dehumidifiers to dry the affected areas. This can be a lengthy process, but it is essential to preventing the return of the mold. Once the area has been dried, any mold-damaged materials need to be replaced.
Once the job is completed, a final inspection is conducted to ensure that the area has been properly contained and treated. Then, the affected areas are reopened to the occupants. It is best to leave a mold remediation company handle these jobs, because they know the correct procedures for containing and treating mold. Attempting to do this on your own could lead to cross-contamination of clean, unaffected areas of the house. A few days before the remediation company is due to arrive, it is a good idea to move all furniture and other items that are unaffected by the mold into another room.
Mold remediation involves not only cleaning up the existing mold, but also preventing future growth by identifying and fixing the moisture source. This involves several steps including: inspection, testing, containment, cleaning, sanitizing, and drying. To avoid further damage, it is important to hire a professional company that understands the importance of these procedures.
To begin the process, the company will perform a thorough inspection to identify the type and extent of the contamination. Then, they will test the air for mold spores and the humidity in the area. This will allow them to determine the best plan for mold removal and treatment.
If the mold growth is limited to one small area, they will use containment techniques to isolate the affected area from the rest of the home or business. This is usually done by closing off the space with plastic sheeting and duct tape. Then, they will close all doors and windows between the contaminated room and other rooms. This will prevent airborne spores from traveling throughout the home or business.
Porous materials such as carpeting and fabric-covered furniture will be removed and disposed of according to local regulations. They will also clean porous surfaces like drywall and wood wall studs with commercial-grade antimicrobial sprays to kill any remaining mold spores. They will then dry the cleaned materials with fans and dehumidifiers to ensure there is no residual moisture left.
If there is a significant amount of mold damage, the professionals will remove building materials such as drywall and insulation that are not salvageable and replace them with new material. They will also clean ductwork and HVAC systems with negative air machines to remove spores from the circulating air.
Finally, the professionals will use a commercial-grade biocide to sterilize the affected areas of the house or business and render them sterile so they can’t grow anymore. After this step, they will install new insulation and drywall, and nail the new drywall to the wooden wall studs. Once everything is dry, the sanitized rooms will be sealed with a waterproof paint that contains a mildewcide to prevent mold from growing in the future.
