Are do it yourself mold test kits accurate and reliable?

, , , ,

Are do-it-yourself mold test kits accurate and reliable? Do-it-yourself (DIY) mold test kits can vary in accuracy and reliability. While they can provide some indication of the presence of mold in a given area, they may not always offer a complete and accurate assessment of the extent or type of mold contamination. Here are a few factors to consider:

Are do it yourself mold test kits accurate and reliable?

Are do-it-yourself mold test kits accurate and reliable?

1. Limited scope: Do-it-yourself kits usually involve collecting a sample from a single location or surface, which may not represent the overall mold presence in a building. Mold can be airborne, hidden within walls, or in other areas beyond the tested surface. Therefore, do-it-yourself kits may not comprehensively analyze the mold situation.

2. Inaccurate identification: It can be challenging for the average person to accurately identify different types of mold based solely on visual inspection. Do-it-yourself kits often use visual identification, which may lead to incorrect mold species identification. Certain molds require professional analysis to determine their potential health risks accurately.

3. Lack of expertise: Conducting a mold test requires proper training and expertise to ensure accurate results. DIY kits may not provide the necessary guidance or support to correctly sample and interpret the results. Conversely, professionals have the experience to conduct more reliable and comprehensive mold assessments.

4. False positives or negatives: DIY kits can produce false positive or negative results. False positives may occur due to mold spores being naturally present in the environment or due to improper sampling methods. False negatives can occur if mold is present but not effectively captured in the samples provided.

5. Professional validation: It is generally recommended to consult a professional mold inspector or industrial hygienist to perform a comprehensive assessment if you suspect mold issues in your home. Professionals can access specialized equipment and training to identify, quantify, and provide informed recommendations for remediating mold problems.

In summary, while do-it-yourself mold test kits can provide some initial indications of mold presence, they may not always be accurate or reliable. For a more comprehensive assessment and reliable analysis, it is advisable to consult a professional mold inspector or industrial hygienist.

Evaluating the Potential for Radon

Evaluating the Potential for Radon

Radon testing is essential in evaluating the potential for radon in a home or building. Radon is a naturally occurring radioactive gas found in soil and rocks. It is released into the air when these materials are disturbed or exposed to the elements. Radon is a serious health hazard and can cause lung cancer when inhaled in high concentrations. Radon testing is the only way to accurately measure the level of radon present in a building and help determine whether or not there is a risk of exposure.

Radon Testing

Radon Testing

Several different types of radon testing can be used to evaluate potential radon exposure. The most common type of test is a charcoal canister test, which typically takes three to seven days. During this test, a canister is placed in the basement or other house area and left in place for some time. At the end of the test, the canister is analyzed to measure the amount of radon present.

Another type of radon testing is the long-term test, which typically takes one to two months. This test uses a continuous monitoring device that records the radon levels throughout the test period. This test is essential for identifying the average amount of radon in a building over time.

When evaluating the radon potential, it is essential to understand the risks associated with these tests. All tests come with some degree of uncertainty and should be done by a qualified professional who can advise you on the best test for your situation. Additionally, it is essential to understand that the results of a test may be less than 100% accurate and may need to be verified with a follow-up test.

Radon testing is an integral part of evaluating potential radon exposure. It is essential to understand that there is a certain amount of uncertainty associated with testing and that the results should always be verified with a follow-up test. Additionally, it is essential to understand the risks associated with these tests and to ensure that they are done by a qualified professional. By understanding these issues, you can make an informed decision about radon testing and ensure that your home or building is safe from radon exposure.

Asbestos Cement Siding Inspection

Asbestos cement is a composite material consisting of Portland cement reinforced with asbestos fibers.  When manufacturers figured out ways to produce siding made using asbestos cement, it became very popular for a number of years before being banned in the U.S. in the 1970s.  Orange County home inspectors are likely to come across this form of exterior cladding during inspections.  Inspectors and homeowners alike can benefit from knowing more about how the known health risks of asbestos apply to asbestos cement siding, too, as well as some of the common problems and issues associated with the material’s damage and deterioration.

HistoryAsbestos Cement Siding Inspection

Asbestos cement first came into use as an exterior cladding after 1907, when Austrian engineer Ludwid Hatschek came up with a way to shape the material into sheets, allowing it to be manufactured as siding and shingles.  By the 1920s, the National Board of Fire Underwriters recommended that asbestos cement replace wood as siding and roofing material because of its superior fire-resistant properties.  This recommendation from a nationally known insurance board contributed to a boost in sales and, by the 1940s, hundreds of thousands of homes in the U.S. had been constructed using asbestos cement siding.

During the late 1960s and early ‘70s, however, the news media began to report on the health hazards associated with asbestos.  As reports increased, concern grew, so the federal government took action and, in 1973, the EPA banned the use of asbestos in the manufacture of building products.

Health Risks Associated with Asbestos Cement

Asbestos fibers are a proven health hazard if inhaled.  Asbestos dust is a known cause of a type of lung cancer called asbestosis.  Mesothelioma, another deadly form of cancer that attacks internal organs, can also be caused by exposure to asbestos.  However, asbestos cement siding that has been properly installed and is not in a state of decay presents no health risks as long as it remains undisturbed.  This is because the cement binds the asbestos fibers and prevents their release into the air, under normal use and maintenance.

The EPA deems asbestos to be hazardous when it is in a friable state, meaning that it can be crumbled, crushed or pulverized by hand pressure.  Crushed asbestos in a powdery form can allow its particles to become airborne and inhaled, causing potential health problems.  Asbestos cement products that are not in a friable state are not considered hazardous.  The only potential danger is when the cement is disturbed in a way that causes the asbestos fibers to become airborne.

If mechanical activities performed on the siding, such as chipping, sawing, grinding or sanding, allow particles to become airborne, then the cement is considered in a friable state and, consequently, hazardous.  Deterioration can also lead to particles becoming airborne and potentially dangerous.

AdvantagesAsbestos Cement Siding Inspection

  • Asbestos cement siding is highly fire-resistant and will not burn or melt the way vinyl and wood siding will.
  • It resists termite damage.
  • It resists rotting.
  • It has been manufactured with textures intended to simulate the look of other cladding materials, such as wood grain.
  • It is fairly easy to clean and maintain.
  • Unlike more porous siding materials, such as wood clapboard, asbestos cement siding will not quickly soak up paint, which allows it to be painted more easily.

Disadvantages

  • Asbestos cement siding is very brittle and can be easily chipped, cracked or broken.  Asbestos Cement Siding Inspection
  • The use of a pressure washer for maintenance can crack the siding and lead to moisture intrusion, if the pressure setting is high enough.
  • Asbestos cement can be dangerous if pulverized by sawing, sanding, breaking, etc.
  • It is difficult to find replacement siding for repairs.
  • This product cannot be refurbished, unlike other forms of siding.  Wood clapboard, for example, can be sanded and re-painted, and cedar shake siding can be sand-blasted and re-stained.  Either of these methods can restore wood close to its original state.  But this is not possible with asbestos cement siding.
  • It is no longer considered aesthetically desirable.

Maintenance

Damage and deterioration can lead to structural and health issues, so proper maintenance of asbestos cement building materials is a primary concern.  Keeping the siding clean and performing any minor repairs as soon as they become necessary are both important.

Asbestos cement siding is fairly brittle and has little resistance to cracking, chipping and damage from impact, which can cause asbestos particles to become airborne.  Damage to the siding can also lead to other damage related to moisture intrusion.  Damaged areas that cannot be fixed can be replaced with non-asbestos fiber cement by a professional.  Specific fiber cement materials have been manufactured for repairs that are intended to mimic the look of asbestos cement siding.

Landscaping features, such as a row of shrubs, can be incorporated around the home to help protect the siding from impact damage.

Homeowner Tips

Here are some common problems associated with asbestos cement siding that homeowners are likely to encounter:

  • Chipping and cracking often occur with this brittle material.
  • Fasteners used to hold the siding in place may deteriorate at a faster rate than the siding.
  • Discoloration and staining may occur from corrosion or runoff from an adjacent material.  The discoloration may be normal, but it could also indicate a chemical reaction that has decreased the durability of the material.
  • Like many other cement products, efflorescence may appear on asbestos cement siding.  This crystalline growth can indicate that water is passing through the material, promoting deterioration of the cement.
  • Biological growth, such as moss and algae, can occur if conditions are favorable.  This growth may stimulate surface deterioration and staining.
Because it was such a popular cladding material for many years, inspectors are likely to encounter asbestos cement siding when inspecting exteriors.  Knowing some of the health risks associated with this material can be useful when answering clients’ questions about asbestos, although any specific concerns should be deferred to the appropriate healthcare professional.  Homeowners will want to hire an InterNACHI inspector for the periodic inspection of this type of cladding as part of their annual or regular home maintenance

Air Sampling for Mold Inspections

Taking air samples during a mold inspection is important for several reasons.  Mold spores are not visible to the naked eye, and the types of mold present can often be determined through laboratory analysis of the air samples.  Having samples analyzed can also help provide evidence of the scope and severity of a mold problem, as well as aid in assessing human exposure to mold spores.  After remediation, new samples are typically taken to help ensure that all mold has been successfully removed.

Air samples can be used to gather data about mold spores present in the interior of a house.  These samples are taken byAir Sampling for Mold Inspections using a pump that forces air through a collection device which catches mold spores.  The sample is then sent off to a laboratory to be analyzed.  InterNACHI inspectors who perform mold inspections often utilize air sampling to collect data, which has become commonplace.

Air-Sampling Devices

There are several types of devices used to collect air samples that can be analyzed for mold.  Some common examples include:

  • impaction samplers that use a calibrated air pump to impact spores onto a prepared microscope slide;
  • cassette samplers, which may be of the disposable or one-time-use type, and also employ forced air to impact spores onto a collection media; and
  • airborne-particle collectors that trap spores directly on a culture dish.  These may be utilized to identify the species of mold that has been found.

When and When Not to Sample

Samples are generally best taken if visual, non-invasive examination reveals apparent mold growth or conditions that could lead to growth, such as moisture intrusion or water damage.  Musty odors can also be a sign of mold growth.  If no sign of mold or potential for mold is apparent, one or two indoor air samples can still be taken, at the discretion of the inspector and client, in the most lived-in room of the house and at the HVAC unit.

Outdoor air samples are also typically taken as a control for comparison to indoor samples.  Two samples — one from the windward side and one from the leeward side of the house — will help provide a more complete picture of what is in the air that may be entering the house through windows and doors at times when they are open.  It is best to take the outdoor samples as close together in time as possible to the indoor samples that they will be compared with.

InterNACHI inspectors should avoid taking samples if a resident of the house is under a physician’s care for mold exposure, if there is litigation in progress related to mold on the premises, or if the inspector’s health or safety could be compromised in obtaining the sample.  Residential home inspectors also should not take samples in a commercial or public building.

MoldSafe

Where to Sample and Ideal Conditions

In any areas of a house suspected or confirmed to have mold growth, air samples can be taken to help verify and gather more information.  Moisture intrusion, water damage, musty odors, apparent mold growth, or conditions conducive to mold growth are all common reasons to gather an air sample.  Samples should be taken near the center of the room, with the collection device positioned 3 to 6 feet off the ground.

Ten minutes is an adequate amount of time for the air pump to run while taking samples, but this can be reduced to around five minutes if there is a concern that air movement from a lot of indoor activity could alter the results.  The sampling time can be reduced further if there is an active source of dust, such as from ongoing construction.

Sampling should take place in livable spaces within the house under closed conditions in order to help stabilize the air and allow for reproducibility of the sampling and measurement.  While the sample is being collected, windows and exterior doors should be kept shut other than for normal entry and exit from the home.  It is best to have air exchangers (other than a furnace) or fans that exchange indoor-outdoor air switched off during sampling.

Weather conditions can be an important factor in gathering accurate data. Severe thunderstorms or unusually high winds can affect the sampling and analysis results.  High winds or rapid changes in barometric pressure increase the difference in air pressure between the interior and exterior, which can increase the variability of airborne mold-spore concentration.  Large differences in air pressure between the interior and exterior can cause more airborne spores to be sucked inside, skewing the results of the sample.

Difficulties and Practicality of Air Sampling

It is helpful to think of air sampling as just one tool in the tool belt when inspecting a house for mold problems.  An air sample alone is not enough to confirm or refute the existence of a problem, and such testing needs to be accompanied by visual inspection and other methods of data collection, such as a surface sample.  Indoor airborne spore levels can vary according to several factors, and this can lead to skewed results if care is not taken to set up the sampling correctly.  Also, since only spores are collected with an air sample and may actually be damaged during collection, identification of the mold type can be more difficult than with a sample collected with tape or a cultured sample.

Air samples are good for use as a background screen to ensure that there isn’t a large source of mold not yet found somewhere in a home.  This is because they can detect long chains of spores that are still intact.  These chains normally break apart quickly as they travel through the air, so a sample that reveals intact chains can indicate that there is mold nearby, possibly undiscovered during other tests and visual examination.

In summary, when taken under controlled conditions and properly analyzed, air samples for mold are helpful in comparing relative particle levels between a problem and a control area.  They can also be crucial for comparing particle levels and air quality in an area before and after mold remediation.
