Before any mold is released for production (“blue-tagged”), it is imperative to put the mold through a series of final-check bench procedures to verify “All Systems Go” and minimize any opportunities for the mold to be stopped and returned to the shop for something that should have been caught before it was released. Water leaks, heater problems, etc., can be avoided with a final-check procedure.
Mark the damaged drywall with a pencil after you determine the area of drywall you want to remove. Use a straightedge to mark lines vertically and horizontally on the face of the drywall. Whenever possible, have the lines fall over the centers of the framing members behind the drywall; this will provide backing and a fastening surface for the drywall patch.
When you’re sure the mold has been eliminated, seal the wood surfaces with pigmented shellac like BIN or an oil-based primer like KILZ. Repaint cleaned wall surfaces with a regular latex paint that contains a mildewcide to help stop future mold growth. Then install new insulation and drywall and nail the trim back on. And keep in mind that if the moisture returns, mold will return.
If you’re dealing with anything other than a large incursion, you understandably may be considering handling the cleanup and drying yourself to save money or time. The problem is that cleaning up and recovering from water damage isn’t always as straightforward as it seems. This post highlights 3 key things you need to be aware of when addressing water damage from a minor clean water (or Category 1) incursion.
Water damage is a serious problem that needs immediate attention fast. The faster water damage is treated, the more furniture and valuable items are saved from permanent damage. Water damage may happen at any time and the most common cause is flooding. Floods may be caused by natural disasters such as hurricanes and excessive rainfall. Sometimes flooding may occur due to leaking faucets, broken sewage pipes, and waste buildup under sink drains.
Black water contains pathogenic agents and is grossly unsanitary. Anyone with a compromised immune system, respiratory problems, or allergies, as well as young children and the elderly must remain off the job site until the building is judged safe for occupancy. Black water includes sewage and other contaminated water sources entering or affecting the indoor environment, such as: toilet backflows, flooding from seawater, ground surface water, and rising river water. Category 3 water can contain contaminants such as pesticides, heavy metals, or toxic substances.
Indoor and outdoor pipes and faucets. Routinely check indoor pipes under cabinets and sinks for leaks, rust, and any signs of deterioration. Minimize the potential for water damage from frozen and broken outdoor pipes by insulating supply lines (in attics, crawlspaces, and exterior walls), protecting exposed outdoor faucets, sealing gaps in exterior walls, and maintaining adequate heat in your home.
Water damage can originate by different sources such as a broken dishwasher hose, a washing machine overflow, a dishwasher leakage, broken/leaking pipes, flood waters and clogged toilets. According to the Environmental Protection Agency, 13.7% of all water used in the home today can be attributed to plumbing leaks. On average that is approximately 10,000 gallons of water per year wasted by leaks for each US home. A tiny, 1/8-inch crack in a pipe can release up to 250 gallons of water a day. According to Claims Magazine in August 2000, broken water pipes ranked second to hurricanes in terms of both the number of homes damaged and the amount of claims (on average $50,000 per insurance claim) costs in the US. Experts suggest that homeowners inspect and replace worn pipe fittings and hose connections to all household appliances that use water at least once a year. This includes washing machines, dishwashers, kitchen sinks and bathroom lavatories, refrigerator icemakers, water softeners and humidifiers. A few US companies offer whole-house leak protection systems utilizing flow-based technologies. A number of insurance companies offer policy holders reduced rates for installing a whole-house leak protection system.
