Mold Infested Condo Development

Monday, October 18th, 2010

Headlines regarding a mold infested condo development generated conversation, confusion and concern following a September 8, 2010, Seattle Times report.

It will take a reported $4 million to repair the Riverwalk at Redmond condo complex where water damage has riddled some units with toxic mold.  Members of the homeowners association appear to have little recourse for what it says is shoddy construction.  Water has damaged 15 units, affecting three of the five buildings on Northeast Leary Way.

The Times article described the plight of the Dusi family, whose lives have been turned upside down by the severe mold in their unit.  They have completely abandoned rooms, and ripped out and replaced drywall as mold has moved throughout their unit.  Their 4-year old developed a spotty rash on her legs and has required frequent hospital visits for respiratory infections and allergies.

Although mold is a very common phenomenon in homes, apartments and commercial buildings, new stories such as the one affecting the owners of The Riverwalk at Redmond often spur interest and demand for more information on mold.

It becomes even more relevant as remodel jobs become a larger part of MBAKS member’s business.  Mold is oftentimes found in crawls, attics or behind sheetrock during remodel activities.

I thought some facts regarding how mold may impact the health of your clients and/or future tenants would be helpful…

1.    Mold growth in buildings is a symptom of water damage or moisture problems.
2.    Dampness in buildings can promote other exposure sources including dust mites, cockroaches, bacteria, and chemical releases associated with some building materials.  Due to the possible presence of these agents, accurately attributing particular health issues specifically to mold may seem logical, but can be disputed.
3.    None-the-less, exposure to mold has been recognized as a potential health problem.
4.    The strongest evidence exists between indoor mold exposure and upper and lower respiratory health effects such as nasal symptoms and asthma exacerbations.
5.    Molds do produce volatile compounds, spores and other minute particles that can cause irritant and allergic responses ranging from annoying to serious depending on the amount of exposure and the immune system of the individual.
6.    Dead mold is still allergenic, and some dead molds are potentially toxic.
7.    The presence of toxic mold does not mean it will kill you.

Everyone’s immune system handles exposures differently.  Thus, mold may affect members of a household differently, with some feeling no effects while others may experience possibly dramatic reactions.

“If you’ve got mold indoors, that needs to be dealt with,” says David Williams, an investigator for Public Health – Seattle, King County.

Bleach and Kilz, both commonly used by consumers for mold, are neither advisable, nor acceptable according to most commercially accepted remediation protocol.  Bleach in particular, is only recommended for hard, non-porous surfaces like tile, countertops and tub and shower basins.  However, it is ineffective as a biocide to kill mold in joist, framing members, roof decking, OSB and plywood as it is unable to penetrate the porous nature of those materials.  As a result, the hyphae, or roots of the mold remain alive and viable – despite the fact that the mold stain may have been bleached away.

So, if you’re dealing with mold, either personally, in a property that you own, on a remodel job, or speculatively through foreclosures, seek the advice of a mold professional to reduce the possibility of adverse health effects to occupants and potential down-line liabilities.

How To Remove Mold Stains From Fabric?

Friday, October 15th, 2010

Mold can leave stains on fabric if left too long.  Here are some steps to follow for mold stain removal.

  • Start by taking the item in question outside, to prevent the spread mold spores indoors, and brush or wipe off as much of the mold off as you can.
  • Allow the item to dry in the sun for a while. Direct sunlight can often kill many different types of mold spores.
  • After plenty of sunlight has been distributed over the item, presoak it in cold water with a MMR and water solution, color safe cleaner if it has colors in it. After the soaking period, machine wash it with warm water and detergent.
  • Lemon juice and salt in cold water has also been used reported to work on colored fabrics, as well as a vinegar solution to aid in smell removal.
  • Hang the item in the sun again to dry.

Mold will leave stains but by using these steps and washing materials in this manner, you will have removed the mold and most likely the musty smell as well, however removing mold stains is an entirely different matter.  MMR mold stain remover is a great resource to remove mold stains.  Before using on fabric, be sure to check an area first for color fastness.

Concrete mold removal

Concrete is used more than any other man-made material in the world. Everything from architectural structures to foundations, roads, and bridges utilize the strength and durability of concrete. Unfortunately over time, aerobic bacteria and mold can present themselves on the surface of concrete and cause strength loss, dramatically decreasing the integrity of the structure.

Introducing DURABAN; the long-lasting, water-based antimicrobial technology that protects your concrete from bacteria, mold & mildew, while also protecting your family, business, and environment from toxic chemicals and mutagenetic bugs. The inherent properties of concrete provide an excellent environment for pathogens and mold to grow causing odor, staining, quality and durability deterioration, and sickness. After just ONE treatment with DURABAN, your ceramics will be free from health hazardous and aesthetically distasteful mold and mildew growth.

In the following lab study, DURABAN antimicrobial has proven to be effective in protecting concrete from mold and microbial growth:Concrete mold removal
