How to Prevent Mold Growth After Water Damage

Posted on by msi-admin

Water damage can wreak havoc on your home, and one of its most persistent and hazardous consequences is mold growth. Mold can start growing within 24-48 hours after water exposure, causing health risks and structural damage if left unchecked. Fortunately, with prompt action and the right steps, you can prevent mold from taking hold in your home.

Here’s a comprehensive guide to preventing mold growth after water damage.

1. Act Fast: Time is Critical

Mold thrives in moist environments, so addressing water damage quickly is essential. The longer water sits, the more likely mold spores will spread and grow.

What to Do:

  • Begin water removal immediately.
  • Contact a professional restoration company if the damage is extensive.

2. Remove Standing Water

Standing water creates an ideal breeding ground for mold. Use tools like wet/dry vacuums, mops, and towels to remove as much water as possible.

Pro Tip: If the area is heavily flooded, call a professional for safe and efficient water extraction.

3. Dry the Area Thoroughly

Even after water is removed, damp materials and surfaces can still promote mold growth.

Steps to Take:

  • Use fans and dehumidifiers to speed up the drying process.
  • Open windows and doors to improve ventilation (weather permitting).
  • Remove soaked carpets, padding, and furniture to dry them separately.

Key Tip: Monitor humidity levels using a hygrometer. Keep indoor humidity below 50% to inhibit mold growth.

4. Dispose of Unsalvageable Items

Some materials are difficult to dry completely and may need to be discarded to prevent mold.

Items to Watch:

  • Water-damaged drywall and insulation.
  • Carpets and rugs soaked for over 24-48 hours.
  • Upholstered furniture and porous items like books or cardboard.

Pro Tip: Always follow local disposal regulations for damaged items.

5. Clean and Disinfect Affected Areas

Cleaning surfaces after water damage helps remove any mold spores that may have already settled.

What to Use:

  • A mix of detergent and water for general cleaning.
  • A solution of one cup of bleach to one gallon of water for hard surfaces (never mix bleach with ammonia or other cleaners).

Important: Wear protective gear, such as gloves and masks, when cleaning to avoid exposure to mold spores.

6. Inspect Hidden Areas

Mold often grows in hidden places, such as behind walls, under flooring, or in HVAC systems.

Key Areas to Check:

  • Inside wall cavities.
  • Underneath carpets and floorboards.
  • Behind large furniture or appliances.

Tip: If you suspect mold in hidden areas, consider hiring a professional for a thorough inspection.

7. Replace and Repair Damaged Materials

Some materials, like drywall, insulation, and wood, can retain moisture even after drying. Replacing them reduces the risk of future mold growth.

What to Replace:

  • Severely water-damaged drywall and insulation.
  • Warped wood or compromised structural materials.

8. Prevent Future Water Damage

The best way to combat mold is by stopping water damage before it starts.

Preventative Measures:

  • Fix leaky roofs, pipes, and appliances promptly.
  • Ensure gutters and downspouts direct water away from your home.
  • Seal windows, doors, and foundations to prevent water infiltration.

9. Use Mold-Resistant Products

When rebuilding after water damage, opt for mold-resistant materials to safeguard your home.

Options Include:

  • Mold-resistant drywall.
  • Mold-inhibiting paint.
  • Moisture-resistant flooring.

Top 10 Signs of Water Damage in Your Home

Posted on by msi-admin

Water damage can be sneaky, often hiding in plain sight and causing extensive issues if left untreated. Recognizing the early signs is essential to prevent costly repairs and maintain the safety and value of your home. Here are the top 10 signs of water damage that every homeowner should know:

1. Water Stains on Walls or Ceilings

Discolored patches on walls or ceilings, often yellow or brown, are classic signs of water damage. These stains indicate that water has seeped through and dried, leaving behind minerals and residues.

What to Do: Check above or behind the stain for leaks, such as a damaged roof or plumbing issue.

2. Peeling or Bubbling Paint and Wallpaper

Water behind walls can cause paint or wallpaper to lose adhesion, leading to peeling, bubbling, or warping.

What to Do: Remove the affected material to inspect the underlying wall for moisture and damage.

3. Warped or Swollen Flooring

Hardwood, laminate, or tile floors that buckle, crack, or swell are clear indicators of water intrusion. This often happens when water seeps under the flooring and causes the materials to expand or weaken.

What to Do: Investigate nearby water sources like plumbing or appliances for leaks.

4. A Musty or Damp Odor

A persistent musty smell often signals hidden water damage, especially if mold or mildew is present. Basements, attics, and areas with poor ventilation are common culprits.

What to Do: Look for damp surfaces and mold growth. Use a dehumidifier to reduce moisture levels while addressing the source of the smell.

5. Mold Growth

Mold thrives in moist environments and can appear as dark spots or fuzzy patches on walls, ceilings, floors, or even furniture. It’s a strong indication of excessive moisture.

What to Do: Mold remediation is essential. Depending on the extent of growth, you may need professional help to remove it safely.

6. Increased Water Bills

An unexplained spike in your water bill could indicate a hidden leak somewhere in your plumbing system. Even small leaks can waste significant water over time.

What to Do: Inspect your plumbing fixtures and pipes for signs of dripping or pooling water.

7. Cracks in Walls or Foundations

Water can seep into foundation cracks, expanding them over time and potentially weakening the structure of your home. Look for new or worsening cracks in walls, ceilings, or basement floors.

What to Do: Seal the cracks and ensure proper drainage around your home to prevent water pooling near the foundation.

8. Sagging Ceilings or Walls

A ceiling or wall that appears to sag or bulge may have water trapped behind it. This can pose a safety risk as the structure weakens over time.

What to Do: Act quickly to drain the water and repair the structural damage before it worsens.

9. Dripping or Pooled Water

Visible water is the most obvious sign of water damage. Check for puddles near appliances, plumbing, windows, or doors.

What to Do: Clean up the water immediately and locate the source to prevent further damage.

10. Rust or Corrosion

Metal components, like pipes, water heaters, or fixtures, may show signs of rust or corrosion when exposed to moisture over time. This is often a sign of ongoing leaks.

What to Do: Repair or replace the affected components and address the underlying moisture problem.

Why Addressing Water Damage is Critical

Ignoring water damage can lead to:

  • Structural issues like weakened walls, floors, or foundations.
  • Mold growth, which poses health risks.
  • Expensive repairs as the damage spreads.

The Pros & Cons of Using Ozone Machines

Posted on by msi-admin

When disaster strikes—whether it’s a flood, fire, or a crime and/or trauma scene cleanup—restoration professionals often rely on specialized equipment to bring buildings back to safe, habitable conditions. One of the tools used in disaster restoration is the ozone machine, a device that releases ozone gas (O₃) into the air to help eliminate odors, kill mold spores, and neutralize airborne contaminants. While effective, ozone machines come with both benefits and potential drawbacks. Here’s an in-depth look at how they function in disaster restoration and the pros and cons to consider before using them.

What Is an Ozone Machine, and How Does It Work?

An ozone machine generates ozone gas by splitting oxygen molecules (O₂) into individual oxygen atoms that then bind with other oxygen molecules to create ozone (O₃). This third oxygen atom is highly reactive, allowing ozone to attach to and break down odor-causing particles, bacteria, and mold spores. This powerful oxidizing effect can make ozone machines useful in disaster restoration work, but it also means they must be used carefully and correctly.

Pros of Using an Ozone Machine in Disaster Restoration

1. Effective Odor Removal

  • Benefit: Ozone machines are well-regarded for their ability to neutralize strong, persistent odors caused by smoke, mold, mildew, water damage and the odors related to crime and trauma scene cleanup. In cases of fire or smoke damage, for example, these machines can help eliminate the burnt smell, leaving the space fresh.
  • How It Works: Ozone gas interacts with odor-causing particles on a molecular level, oxidizing them and breaking them down, which effectively removes the smell rather than merely masking it.

2. Mold and Mildew Control

  • Benefit: Ozone gas is known for its ability to kill mold spores in the air, making it a useful tool in mold remediation. Mold can release spores that not only spread further but can also affect indoor air quality.
  • How It Works: The ozone penetrates into small crevices where mold spores can hide, helping to sanitize areas that may be difficult to reach with other mold removal methods.

3. Reduction of Bacteria and Viruses

  • Benefit: Ozone machines can help reduce the presence of bacteria and viruses in an affected space. In restoration after floods or water damage, for instance, bacteria can often flourish, creating sanitation issues.
  • How It Works: The oxidation process involved in ozone treatment can damage the cell walls of microorganisms, effectively neutralizing bacteria and viruses

4. Non-Toxic Residue

  • Benefit: Once ozone breaks down, it reverts back to oxygen, leaving no toxic residue. This contrasts with some chemical disinfectants that may leave residues requiring additional cleanup.
  • How It Works: Because ozone is a gas that naturally breaks down over time, it dissipates quickly once the machine is turned off and the space is ventilated, reducing chemical impact on the environment.

Cons of Using an Ozone Machine in Disaster Restoration

1. Health Risks for Humans and Pets

  • Drawback: Ozone is a powerful oxidizing agent, which can irritate the respiratory tract, causing symptoms such as coughing, chest discomfort, and throat irritation. It is also harmful to pets, plants, and other living organisms.
  • Consideration: Rooms need to be fully vacated when an ozone machine is in use, and treated areas must be thoroughly aired out before re-entry. Restoration professionals should follow all safety guidelines to avoid prolonged exposure.

2. Potential Damage to Materials

  • Drawback: Ozone is known to accelerate the degradation of certain materials, such as rubber, electrical wiring, and some plastics. Overuse in a building can lead to deterioration of items such as carpet backings, insulation, and rubber seals.
  • Consideration: Restoration professionals should limit ozone exposure on sensitive materials and be cautious about where and how often they use ozone in enclosed areas with delicate items.

3. Limited Effectiveness on Certain Types of Mold

  • Drawback: While ozone can kill mold spores in the air, it may not penetrate surfaces deeply enough to eradicate mold colonies growing in porous materials, such as drywall, carpet, or wood. This limits its effectiveness in comprehensive mold remediation, and is basically an additional tool, but not required or to be used as the primary method of mold remediation.
  • Consideration: Ozone treatment should be seen as part of a larger remediation strategy and may be best used as a supplement to other mold removal methods, especially for mold that has already established itself in porous materials.

4. Regulatory and Safety Concerns

  • Drawback: Some regulatory bodies and organizations advise against the use of ozone generators in occupied spaces due to the health risks involved. Ozone’s safety threshold is low, meaning that even minimal exposure can be harmful, and its production is regulated in certain areas.
  • Consideration: Professionals should always check local regulations and ensure they are complying with any guidelines set forth by organizations such as OSHA and the EPA.

5. Temporary Results in Some Cases

  • Drawback: Ozone machines may eliminate odors temporarily, but if the underlying cause of the odor remains—such as water damage that continues to harbor mold—odors may return.
  • Consideration: Ozone treatment is often most effective when combined with comprehensive remediation techniques. For example, water-damaged areas need to be dried and repaired to prevent mold from recurring.

In the realm of disaster restoration, ozone machines can play a valuable role in addressing odors. However, their use should be balanced with caution and awareness of potential drawbacks. While ozone is effective for odor control and surface sterilization, its limitations with deeply embedded mold and its potential impact on health and materials must be carefully managed. When used correctly and in conjunction with other remediation methods, ozone machines can enhance disaster restoration efforts, helping to restore safe, fresh, and habitable spaces after fires, floods, and other disasters.

How Mold Effects Us

Posted on by msi-admin

After pollens, molds are the leading cause of outdoor airborne allergies, which can recur year-round. Some of the most common symptoms of those sensitive to molds include nasal stuffiness, eye irritation, wheezing, cold and flu-like symptoms, rashes, conjunctivitis, inability to concentrate, and fatigue. Mold exposure has also been associated with asthma onset. Symptoms usually disappear when the mold is removed. However, under certain conditions, exposure to mold can cause serious health problems. Some people with chronic illnesses, such as obstructive lung disease, for example, may develop mold infections in their lungs. Also, some people exposed to large amounts of mold at work, such as farmers working with moldy hay, may develop even more severe reactions, including fever and shortness of breath. Some molds are toxic, producing chemicals called “mycotoxins,” which in large doses may affect human health, usually by causing allergy-like symptoms such as watery eyes or eye irritation, runny nose and sneezing or nasal congestion, wheezing and difficulty breathing, aggravation of asthma, coughing, itching, or rashes.

Other health problems that have been linked to mold exposure involve the odors produced by mold “volatiles” during the degradation of substrates. These have been discovered to irritate mucous membranes, and they have been associated with a number of symptoms from headaches and nausea to fatigue in individuals exposed to them. For those suffering from multiple chemical sensitivities, the simple presence of these microbial volatile organic compounds (MVOCs) can trigger a reaction just as strong and serious as exposure to chemical VOCs. Fungi or microorganisms related to them may cause other health problems similar to allergy. Some kinds of Aspergillus especially may cause several different illnesses, including both infections and allergy. These fungi may lodge in the airways or a distant part of the lung and grow until they form a compact sphere known as a “fungus ball.” In people with lung damage or serious underlying illnesses, Aspergillus may grasp the opportunity to invade and actually infect the lungs or the whole body.

In some individuals, exposure to these fungi can also lead to asthma or to an illness known as “allergic bronchopulmonary aspergillosis.” This latter condition, which occurs occasionally in people with asthma, is characterized by wheezing, low-grade fever, and coughing up of brown-flecked masses or mucous plugs. Skin testing, blood tests, x-rays, and examination of the sputum for fungi can help establish the diagnosis. Corticosteroid drugs are usually effective in treating this reaction; immunotherapy (allergy shots) is not helpful. The occurrence of allergic aspergillosis suggests that other fungi might cause similar respiratory conditions. Inhalation of spores from fungus-like bacteria, called “actinomycetes,” and from mold can cause a lung disease called “hypersensitivity pneumonitis.” This condition is often associated with specific occupations. For example, farmer’s lung disease results from inhaling spores growing in moldy hay and grains in silos. Occasionally, “hypersensitivity pneumonitis” develops in people who live or work where an air conditioning or a humidifying unit that is contaminated with these spores emits them.

The symptoms of “hypersensitivity pneumonitis” may resemble those of a bacterial or viral infection such as the flu. Bouts of chills, fever, weakness, muscle pains, cough, and shortness of breath develop 4 to 8 hours after exposure to the offending organism. The symptoms gradually disappear when the source of exposure is removed and the area properly ventilated. If it is not removed, workers having to be in those contaminated areas must wear a protective mask with a filter capable of removing spores or change jobs. If “hypersensitivity pneumonitis” is allowed to progress, it can lead to serious heart and lung problems. Also, air with a high concentration of fungal spores of a number of different types of molds may contain toxins that, when breathed over a long period of time, may result in a kind of poisoning. Stachybotrys atra, a mold that is commonly found on wet cellulose products (for example, drywall) and is causing growing concern among physicians, is one of these molds. In one recent study, it was linked to lung bleeding in infants. This mold has also been linked to sudden infant death syndrome and to central nervous system symptoms such as personality changes, sleep disorders, and memory loss.

Identifying Mold on Carpeting

Posted on by msi-admin

Just because mold is not immediately apparent or visible on a carpet’s surface does not mean that mold growth is not in progress. In fact, mold will probably only be visible on the surface of carpets in unusually severe cases of growth, such as carpet damaged in flooding that has remained wet for some time. The following are some examples of identifiable instances where mold growth has occurred or is likely to occur:

  • Visible Mold Growth: As stated above, this can be a rare case, but sometimes it may be obvious from visual inspection that mold growth is occurring. Carpet in this condition is most likely not salvageable and should be disposed of and replaced. Often, even if mold growth is not visible on the top of carpeting, it may be occurring underneath the carpet where it can’t be easily seen. Carpet suspected of containing mold should always be examined on both sides.
  • Carpet Mildew: Any discoloration or odor on carpeting that might be described as mildew is probably a case of mold.
  • Wet or Water-Damaged Carpet: Any carpet that has been subjected to water damage from flooding or standing water will most likely need to be disposed of. Conditions are ripe for mold growth, in this case. Even if visibly apparent mold growth has not yet begun, it is highly likely to happen unless the carpet is completely removed, cleaned and dried within 24 to 48 hours. Even then, removal and cleaning are not guaranteed to prevent mold growth. It is more likely that the carpet will need to be replaced.
  • Wet Padding Beneath Carpet: If padding beneath the carpet has become wet for any reason, or has become moist from condensation, the padding as well as the carpet on top are at risk for mold growth. The padding may need to be replaced, as will the carpet, in some cases.
  • Basement Carpet: Carpeting in basements below grade level is especially at risk in areas where humidity is high, or where wide temperature swings can produce condensation.
  • Odors and Stains: There is a wide range of things that can cause odors and stains on carpets. If mold is suspected, samples can be taken and sent for analysis to determine if mold growth has occurred.

What is Alternaria?

Posted on by msi-admin

Alternaria is one of the most important allergenic molds found in the US. It is most common as an outdoor mold, as it thrives on various types of vegetation. Alternaria spores can be detected from Spring through late Fall in most temperate areas, and can reach levels of thousands of spores per cubic meter of air. While one usually thinks of molds as a problem in damp or even wet conditions, Alternaria spores can be at their highest concentrations during dry, windy conditions that are ideal for the spores to become airborne.

Alternaria is one of the most common outdoor molds, but also has been found in the indoor environment. The National Survey of Lead and Allergens in Housing conducted a study looking at house dust samples from 831 homes in 75 different locations throughout the US. Alternaria was found in over 90% of those dust samples. While much of that allergenic load was probably due to outdoor Alternaria finding its way inside, Alternaria is known to grow on moist surfaces in the home as well.

Alternaria is known to be a problem in allergic disease. In patients who show allergy to molds, up to 70% of those patients demonstrate allergy to Alternaria, and Alternaria is known to be a risk factor for asthma. Dampness and mold problems have been reported to occur in 20 – 50% of modern homes. Additionally, keep in mind that mold spores often outnumber pollen spores by 1,000 to one, and mold can produce spores for months on end, versus the weeks of pollen production by many allergenic plants.

What is Acremonium? 

Posted on by msi-admin

With wet conditions, Acremonium grows quite well.. When Acremonium is found indoors, it usually originates either from outdoor air or from contaminated crawl spaces or from contaminated building materials that recently experienced wet conditions like flooding. However, the spores of this fungus are formed in a slimy mass resulting in limited aerosolisation: therefore its prevalence may be low in air samples.

It grows indoors on building materials such as drywall, acoustic and thermal fiberglass insulation and in some cases insulated ducting. Crawl spaces, wet bathrooms with a lack of proper ventilation or exhausting and continuous wet basements are ideal for Acremonium. 

Acremonium has often been associated with contamination by Stachybotrys chartarum, which is often referred to as “Black Mold,” as both fungi is favor very wet circumstances. Allergenic reactions to Acremonium includes hay fever, asthma, hypersensitivity and pneumonitis. Potential opportunist or pathogen effects are known to cause hyalohyphomycosis, keratitis, mycetoma, and onychomycosis. Also known to cause infections in immunodeficient patients and causes infections in persons with wound injuries.

When mold is found in your home, trust the professionals at Mold Solutions & Inspections to properly handle the removal the first time under the guidance of the IICRC protocols.
