The Four Letter Word that Frightens Realtors!

As a realtor you know how challenging it is to list a house and then try to find the right buyer for the client. So many things can show up during a home inspection that your client may become discouraged due to past flooding, ice dams, roof leaks, or a pipe that froze. Water intruded throughout some of these areas that now may have suspect mold growth.  Yes ‘mold’ that dirty four letter word that can frighten a buyer away!

 

Mold growth and contamination can cause damage to a house or building if not dealt with properly. There are people who are very sensitive to mold fungi and have allergic reactions, sinus infections, even respiratory problems. People with asthma in general struggle with air quality issues. Did you know that the EPA says, “We spend approximately 90 percent of our time indoors”!

 

Before listing a house it is important to ask questions about past flooding, roof leaks, ice dams, pipes from bathrooms or kitchens bursting etc.  How long did the water leak occur? Was water standing for more than 48hours or less? The best time to dry out excess water problems is within the 48  hour period. After a few days this is usually when mold growth tends to occur.  Do you see dried water stains or stains that are suspect for mold such as in the basement, attic, ceilings, walls, etc. Repairing the source of the problem of moisture and dampness is important to control mold growth from occurring.

 

What about those musty odors? Does the crawlspace or basement have a dirt floor? Has the source of the leak been repaired properly? Is the insulation drooping to the floor of the crawlspace because of excess moisture? Are dehumidifier(s) properly operating when needed? Controlling excess relative humidity is important to help mold growth from spreading. Excess Relative Humidity over 60% R.H. can fuel moisture for mold growth. It is important to install the right size dehumidifiers for the basement or crawlspace. Add quality grade vapor barrier sheeting to the entire dirt floor areas. Replace any drooping or excess moist fiberglass insulation; and of course clean and treat the mold where and if necessary.

 

The good news is that there are solutions to mold growth and contamination. Removal of mold physically  such as wallboard, contents, carpets, furniture, wet or damp insulation, etc. Clean and treat affected areas professionally from a trained and certified (current certifications) company to remediate the mold. You may want to have the person selling their house to consider a mold inspection and moisture assessment before they list the house. Home inspectors usually do the structural aspect of the house. (Beware of labs pushing untrained home inspectors to conduct mold inspections and testing!) Hire an independent professional who is trained, certified and experienced company who does not remediate mold to offer an objective viewpoint for your project.  I emphasize trained and certified because there is no federal state regulations in Massachusetts and other the New England states. Very few states require licensing for mold assessments and removal.

Crawlspace Moisture

Excess Moisture in Crawlspaces

This time of year in the summer months causes concerns for musty odors, excess moisture and mold growth on the surfaces. What’s that smell? Do you know what is going on down in your crawlspace? Does it have a dirt floor? Is the open fiberglass insulation in the floor joist drooped down into the floor? These are signs that excessive moisture and mold contamination growth may be occurring.
Mold spores can and will exacerbate with any excess moisture and excess relative humidity that will cause existing mold spores to travel and move around where new growth can occur. Excess relative humidity in a basement or crawlspace is like adding ‘gas onto the fire’ where spores will grow. The picture in this crawlspace has a vapor barrier over the dirt floor and stapled above the floor joist. Moisture was still dripping with excess moisture in the middle of winter with a relative humidity reading at 79%. There was no dehumidification operating in the crawlspace.
Conducting a thorough visual investigation of the musty odor or any source of water leak, excess moisture is very important. Relative humidity (RH) should be less than 60% or lower to help to control moisture (30% to 50% (RH) is the best range). When (RH) is above 60% or more this is not good for your basement, crawlspace, or living/working space where mold and other contaminants can grow; even causing wood rot and decay to the structural support of the wood beams and joists. To control excess moisture and humidity it is important to install the proper dehumidification system. Too often homeowners and business owners do not have the proper size dehumidifier(s) installed because the square footage or cubic area is too large and the unit does not cover this amount of ambient space.
Crawlspaces with dirt floors should have quality grade vapor barriers with minimal 6 Mil thicknesses or higher covering the entire dirt floor including part of the lower side walls or to the top. Quality grade dehumidification is recommended to help control moisture.
During the hot and humid months less moisture is probable when the outside vents of crawlspace are closed up. Climates are different throughout the country; the Northeast region is different from the Southeast and Southwest regions.
Insulate using foam pipe sleeves any copper pipes underneath the crawlspace or in the basement area. The cold water pipes usually condensate when excess humidity comes in contact with them. Insulate Well Tanks and Water Filter Tanks as well. Dehumidifiers need to drain properly operating on a 24/7basis when needed.
If chronic water leaks or water floods into the basement or crawlspace areas then quality grade sump pump(s) and/or drainage are recommended. Install vinyl grade cover over sump pump area. Sump pump is best installed in the ground and the bucket is deep enough to effectively pump and drain water. Add drainage around perimeter if necessary. A professional can provide the proper assessment with the proper tools to help to determine such factors as relative humidity, temperature, air flows, moisture meters, Thermal Infrared Camera, etc.

Environmental Resources is here to help identify problem areas. Also we provide solutions with products and quality air purification with several pounds of carbon to fight odors. We offer sampling if it is called upon. Call for a professional consultation of your home or business’ indoor air quality today.

Does it really matter the type of mold(s) in my house – building?

Often times when I arrive for a mold assessment/inspection the question often comes up, “Is this the ‘bad mold’ or the ‘good mold’?  My first response is I don’t know because I do not give a physical or verbal interpretation of what I am dealing with. In other words if people are concerned about the types of mold present then sampling will be conducted and sent to a qualified AIHA Microbiological laboratory to determine its species. There may be more than one species  in a suspected room or in the sampling. This is the value of the  lab because I am just the messenger assessing the physical aspects of the property and its building envelope.  it is best find out as much information of the properties history when it has come to past flooding, water leaks, roof leaks, ice dams, past mold contamination, etc.

Getting back to the question of good or bad mold type. My response, to the house or building it does not necessarily matter because the property does not have lungs where humans and animals breathe in the contaminated air.  The mold species are not saying to each other, ” Hey we’re Aspergillus, Cladosporium, Penicillium, or Stachybotrys ‘Black mold’, etc. You get my point. Mold fungi in buildings  will eat at the substrate and organic matter of porous materials such as wallboard, ceilings, cardboard, clothing, furniture, carpets, storage, etc. The source it needs is an excess moisture content such as flooding, water leaks (over 48 hours), excess relative humidity over 60%, etc.  Removing and treating the mold is important to prevent the property from devaluation irrelevant to the type of mold species. In many cases remodeling will also have to be conducted after proper professional cleaning of mold fungi. Remember, the key is to stop the source of the water-moisture problem before remediating.

The importance of good and bad mold to humans and pet is because we are breathing in these allergenic, pathogenic, and toxigenic type mold species. “The term ‘toxic mold’ is not necessarily accurate but there are certain mold fungi that can produce toxins (specifically mycotoxins), the mold themselves are not necessarily toxic or poisonous. ” (See – CDC Mold questions & Answer).

In other words all mold species should be treated the same with respect to health risks and removal, wether good, bad, or the ugly mold species. People with allergies, asthma, immune suppression are more susceptible to potential fungal infections. It is best to consult with an experienced physician when it comes to these type of health problems. Our job is to conduct a professional assessment and inspection not to give any medical advice (which we do not by the way).

One more point. I have heard realtors say to their clients or buyers client that this is not the bad mold!  Again, it is irrelevant to the type of mold in the property. If the property needs professional remediation, then it needs to be addressed professionally and with the proper standard of care. Let us do our job to help point you in the right direction. Environmental Resources does not remediate so we help all parties involved both the buyer and the seller when it comes to the transaction. It is best not to use a remedial company to test and inspect so there is no conflict of interest. Their job is to do the cleaning.  If there are no health concerns but mold is present you don’t always have to test but have the mold removed in a professional manner.

Allergies and Indoor Air Quality

  • There are many types of air particulate that move around in our homes and offices. We buy products,furniture,home goods, and furnishings that most of us do not know what the materials or chemicals they are made from. It has also been said, “that we spend nearly 90% of our time indoors that can affect the quality of our indoor living lifestyles”. Particles like dust, pollen, mold, dander, fibers, odors, etc. can produce allergy triggers that can cause you discomfort. I often get calls from people who immediately think they have a mold problem. Why do you think you have mold? Usually mold is produced from water damage, water leaks, flooding, excess moisture and high relative humidity over 60%.

    No signs of water damage or leaks, no chemical smells, but the house is full of dust, insect and mice droppings, old storage and furniture with films of dust found in all the hidden places behind & underneath furniture, headboards, tops of picture frames, door frames, top sides of ceiling fan paddles, and very high shelves that rarely get cleaned. The vacuum cleaner is rarely used because we are all legitimately busy and continue to remind ourselves with notes that we will get around to eventually cleaning the areas of concern.

    Before spending money having all kinds of testing conducted indoors which can get expensive, I have a few suggestions as pro-active preventative measures:

    A Good General House Cleaning

    Clean from top to bottom. Use a soap or detergent. Some use an anti-microbial disinfectant cleaner which can combat, mold, bacteria, odors, virus, etc.

    Use a Quality HEPA Vacuum

    Vacuum the floors, carpets, difficult areas and high spaces. Remember, if you hire a cleaner have them use your vacuum. You don’t know where there vacuum has been! I have had cases where clients had severe allergy triggers the next day after the house cleaner arrived the day before.

    Dust Thoroughly the entire House

    Use a good Swiffer or Dust Rag. Dust the difficult high places such as shelves or cabinets and hidden places underneath or behind bureaus, furniture. Tops of ceiling fan paddles, picture frames, and where necessary.

    Invest in Quality HEPA Air Purification
    To help clean the air in your space of dust, allergens, mold, fibers, dander, odors, etc. Use them often and move them around because they work!

    A good general cleaning of the basement once a year is recommended. Dust can accumulate fast. While you’re at it some of that storage may need to got hats been sitting there for years. Give it away, have a yard sale or donate it to a local charitable cause

    Should there be some chronic problem with your indoor air quality then it is recommended to call a professional who is trained, certified with experience.

    Independent Mold Assessments

    Mold inspections and mold testing are an important part of the process to determine the extent of a mold contamination problem, especially when it may involve professional mold removal. Too often a mold remediation contractor will try to conduct their own testing or exaggerate an inspection claiming the mold is very extensive when in reality it may not be extensive in the nature and scope of the problem at all. For example, Environmental Resources does not remediate mold or remove toxic mold in homes or businesses. We are an independent consulting firm providing professional environmental inspection services for mold and (IAQ) indoor air quality issues. A real estate company or the potential buyer will call us stating, “There was a home inspection and dark or black stains or what looked like mold fungi species was indicated”. (A mold company was in prior to us coming for inspection proposing a very high cost estimate for mold removal after the buyer called a mold remediation company in Boston MA area).

    An independent visual inspection utilizing the latest instruments and tools to determine water leaks and moisture issues for the source of the problem. Mold sampling was conducted with the inspection and it was determined that the extent of the mold problem or mold damage was not as severe or extensive as was told to the homeowner by the remediation company. The mold assessment was conducted by an independent party and does not remediate (clean) mold which brought assurance and peace of mind to the homebuyer and seller because there was no conflict of interest. The suspect area for mold did need some mold remediation but was not as extensive as first claimed. It is always beneficial to have at least two or three estimates from companies who a qualified, trained, and certified from an independent body. Ask how long they have been remediating mold which may be less than how long they have been in business. Several contractors have jumped on the “Mold Rush” bandwagon so do your homework!

    Independent mold assessments also help insurance claims and insurance adjusters to provide non bias independent professional opinions of indoor mold growth. Many homeowners deal with floods and water leaks in disasters such as hurricanes, flooding, heavy rainfall and high relative humidity which happens often in the Boston, Massachusetts and Cape Cod areas along the entire coast from Maine to Cape Cod. High relative humidity and moisture to mold spores is like putting gasoline on a fire which flares up and spreads the problem even more. Water problems need to be addressed within 24 to 48 hours for the best results for mold prevention and its microbial growth indoors. Our philosophy is that, “An ounce of prevention is better than a pound of cure” or “Do it the right way when it comes to a standard of care or don’t do it at all”! A certified trained professional mold inspector providing mold inspections and mold testing may end up saving $1000’s thousands of dollars in the long run along with peace of mind and assurance. If you think you have a mold problem or are not sure because the mold may be hidden behind a wall or underneath a floor then call a professional. Serving Massachusetts, Cape Cod, Martha’s Vineyard, and Nantucket Islands.
