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.

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.

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.

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.

    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.

    Heavy Floods-Water Intrusion in Basements

    What happens when water stands in a basement for a prolonged period of time? Recently Massachusetts experienced some of the largest rainfall in  a short period of time including 6 to 13 inches of water in a 3 to 4 day span a few years ago. Towns such as Andover, Billerica, Hingham, Topsfield, Peabody, Waltham, Sudbury, Canton, and many others experienced unusual flooding in the homes and businesses.

    The longer the water stands in the basement or building they are prone for active mold growth throughout the affected substrate areas. Water, floods, dampness, moisture are all key ingredients when it comes to mold fungi to grow on substrate sources such as drywall, carpet, furniture, boxes, etc. Toxic mold and black mold can grow even after the drying out process if the area is not dried out properly. The visible mold is the easier areas to handle such as wallboard or ceiling tiles, however, mold spores are not always visibly seen or noticed until after the fact. Such as several weeks or months later when odors begin to arise or a family member may be experiencing some breathing discomfort.

    The to prevent any mold growth is to keep the area clean and dry, preventing moisture from accumulating. A proper mold and moisture professional assessment is a wise choice to prevent this from happening. Environmental Resources uses the latest state of the art technology when it comes to detecting mold and water leaks. A Flir Thermal Infrared Imaging Camera well help detect water and moisture problems. Certified  mold testing and mold inspections utilizing accredited microbiology accredited labs will determine the type of mold species growing and the describe the extent of the growth whether is active or not.
