Freezing Cold Ice Dams Flooding Mold

Ice Dams

Due to the extreme sub zero temperatures and the recent  Nor’easter” Double Bomb Cyclone” here in the Boston area and coastal region many homeowners have experienced flooding including power outages, loss of heat, bursting and frozen water lines. The septic water drain pipes are even freezing leaving homes and businesses to not have toilet facilities and running water.

Gear up for the ice dams next in the coming weeks! The temperatures will rise from sub-zero to up to 50 degrees or more in the Boston and coastal areas. The severe temperature swings will begin to cause ice dams creating damaging affects to your home or business.

People are discovering how cold there home or place of business has become because of the extreme cold swings. Oil fills ups in our area are seven to ten days behind so stay safe and check on your neighbors and pets.

The utilization of Thermal Infrared Camera helps to discover hidden areas of moisture or cold drafts due to temperature differential of the surfaces. It can even help with frozen pipes in the basement or crawlspace before they may burst.

Real Estate and Mold – Moisture Assessments

Mold growth and contamination has become a popular yet hidden subject when it comes to buying and selling a home. What has caused a mold assessment to become more frequent in the past 10 years? Several areas to consider for concern include:

1. The foreclosure crisis in 2008 and 2015 historic ice dams in Massachusetts.
Homes and building were left unattended with nobody overseeing the property when it was vacant. The banks lost enough so why spend more money! Contractors and investors bought many houses with excess mold contamination due to floods, pipes bursting and leaking roof leaks etc. causing mold to grow. Although house were renovated the crucial question was whether the house or affected room were professionally cleaned and treated by a certified trained mold remediation company? The renovations look good but the musty odors are awful.

2. The Ice Dams and water damage of the Winter 2015 in Southern NE brought new challenges and the Storms of the past 10-15 years has brought much awareness due to hurricanes, flooding, nor’easter storms and even the ice dams. Ask questions if flooding, ice dams, leaky roofs or plumbing occurred with the history of the house. Ask if mold contamination and growth was a problem? Ask if proper repairs were properly corrected by removal versus just painting over or putting a ‘band aid’ over the existing problem. If mold remediation was conducted and renovations properly completed (repairing the source of water leaks) and documented.

3. Indoor air quality in general is a growing concern and if you have asthma and/or allergies this may affect your health and breathing! Some people are more sensitive and have a weaker immune system when it comes to mold or excess moisture and excess relative humidity. properly installed dehumidification and sump pumps with drainage where necessary are important.

Remember purchasing or owning your own home is a lifetime investment and the castle you will live inside for numerous hours. Mold contamination can affect your property value and your health. It is wise to ask questions and address the above issues to allow you to breathe easier in the comfort of your home.

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.

Excess Moisture Relative Humidity in Basements-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? These complaints are often called into my office and I ask a few questions such as: Have you been flooded due to the recent heavy rains last spring or prior years. How about roof leaks, pipe leaks, or ice dams? If water intruded into the building or house and flooding occurred, how effective was the cleaning, drying out process ? Did you get to the water early such as within 24 to 48 hours to help avoid potential mold growth problems?

If existing surfaces are spotted with mold spores because the areas were not cleaned out properly then the mold will not disappear! 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.

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 and basements should have quality grade vapor barriers with minimal 6 Mil thickness 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.

If chronic water leaks or water floods into the basement or crawlspace areas then quality grade sump pump(s) are recommended with vinyl covers over the top of recessed bucket. It is best 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.

The Value of Mold Testing

What is the value of mold testing? Too often I have heard that if you see the mold just get rid of it!

This is true to a certain extent however, what if you can smell the mold but can’t see it? There is a strong musty mold odor or some form of dampness. I agree if you see the mold get rid of it and/or have the mold treated, but what about mold that may be hidden or undetected? Mold spores are not visible to the naked eye that are airborne. Just because walls, ceilings, or floors are not moist does not indicate that mold spores are not present. Every building have some forms of mold, we are looking for unusual or excessive mold growth.

The value of mold sampling is Threefold:

  • The air testing will determine the mold spore elevations present in the room if they are excessive beyond our natural environment.
  • The air sampling or direct identification will determine the type of mold species such as mycotoxic, pathogenic,or allergenic.
  • The sampling will determine if the mold is growing actively or is dormant. (Dormant mold is known
  • to be allergenic and can still compromise a building or a persons health)

Another value for a professional mold test and inspection is the peace of mind to know your investment and health are not at risk. Our theme is “An ounce of prevention is better than a pound of cure”.

Mold testing is best to be perormed by a professional  independent company or consultant that does not remediate mold to offer a factual unbiased assessment.

All our samples are sent to qualified labs with trained microbiologists. Certified EMPAT AIHA Labs.

Having personal field experience with hundreds of mold inspections and assessments in the past several years there are times when the mold in the building looks worse than what may appear and at other times the room walls and ceiling look clean and innocent only to find that the room has excessive mold in mycotoxic, allergenic in nature.  Although there are currently no federal standards or guidelines regarding results of fungal samples and there are no levels which are typical or permissible there is still value, especially in finding and correcting the source of the mold such as a water or moisture problem.

Environmental Resources provides qualified and trained professionals to provide sampling and protocol in your mold assessment and mold inspection. We serve all of Massachusetts including Greater Boston, North & South Shore, & Cape Cod-Islands.

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.

Is All Black Mold Toxic?

When homeowners or business owners see or hear of black mold they think of toxic mold? Why? Well the media hype and websites that stress fear rather than solutions to sell you a bill of goods becoming alarmists. There are legitimate cases when it comes to mold and health hazards but most are more allergy induced causing irritable respiratory and breathing problems. Especially for those with chronic asthma and allergies. An example of black mold is in attic where dark or black stains may be visible. A mold that often comes up in New England, Greater Boston, or Cape Cod and the islands of Nantucket and Martha’s Vineyard is usually a cladosporium type species. This is a common mold in the outdoors and the spore counts are much higher than other mold species during the peak of the mold spore elevation season such as Spring, Summer and Fall seasons. As for black toxic mold, which I prefer to as mycotoxin, a species such as Stachybotrys Chartarum or sp. atra. This usually stands in chronic wet areas and is a slow tertiary species. Usually not as airborne as some would think. If stachybotrys species is airborne, it is considered a chronic condition. It’s more of a slimy like substance grayish, greenish more than actual black. Also, other toxic mold species come in a variety of different colors as well, besides black. Remember, the longer water infiltration stands in a basement or living area where the substrate is wet, it has potential for excess mold fungi growth.

For a professional assessment hire a trained certified professional to assess and provide solutions for your home or business.

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.

    Mold May Frighten 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.

    Hurricane Harvey Houston Preventative Measures

    HURRICANE HARVEY PREVENTIVE TIPS!
    Yes we are now in that time of year called Hurricane Season! Safety is always a key concern and we will have you folks in our thoughts and prayers. I have taught many years ago that it is not just the hurricane damage that affects your property but also the after effects with all the standing water and excess humidity. Mold contamination and bacteria can grow at alarming rates. Excess water and humidity is like putting gas to the fire.

    It is important once you come back to your property to effectively dry out all the areas and remove all water damage and mold contents. Calling a professional is highly recommended (in Harvey’s case 36 + inches of water and then some is a large mass of water). The excess relative humidity will begin to cause a lot of mold growth and contamination that can cause just as much damage as the flood.

    Insurance companies and adjusters will be scrambling so do not wait sometimes it takes days or weeks to see damage.
    Document everything with pictures, video, and keep all receipts of any urgent repairs.

    Note you do not have to choose the restoration company the insurance company recommends usually national franchise chains. You can choose your own make sure they are licensed, certified, trained, established companies
    Do not hire out of state contractors they won’t be there after they get their check! If it is a necessity, ask restoration companies and independent assessors for their current active certifications for training.
    When going back to your property be prepared to wear proper safety gear such as HEPA mask Niosh N-95 or better, gloves, Tyvek coverall suit. Etc.
    Be careful of electrical wires and the water supply sewerage, drinking water, etc. Drink bottled water.
