Common Causes of Mold Damage

Mold can grow quickly and spread silently, often resulting in significant damage to your property and health risks to your family. Here are some of the most common causes of mold damage:

1

Water Leaks

Persistent leaks, whether from pipes, plumbing fixtures, or appliances, create the perfect environment for mold growth. If left unaddressed, even small leaks can lead to major problems.

2

Poor Ventilation (Bathrooms, Attics, etc.)

Areas lacking proper airflow, such as bathrooms and attics, hold onto moisture, which can trigger mold growth. Steam from showers or warm air trapped in attics needs effective ventilation to prevent mold proliferation.

3

Humidity and Condensation

Excessive humidity or moisture in your property can cause condensation to form on surfaces such as walls and windows. This damp environment creates the perfect conditions for mold to develop and spread.

4

Flooding

After flooding, water seeps deep into materials like carpets, drywall, and furniture. The prolonged dampness creates an ideal breeding ground for mold, often requiring professional intervention.

5

Roof Leaks

Water intrusion from a damaged or aging roof often goes unnoticed until the mold becomes visible. Roof leaks affect attics and ceilings, spreading mold spores throughout your home.

6

Foundation Leaks

Cracks or gaps in your foundation allow water to seep into basements or crawl spaces. This persistent moisture encourages mold to grow in hard-to-reach areas.

7

Poorly Installed or Damaged Insulation

Substandard or compromised insulation can trap moisture within walls, creating hidden pockets where mold can flourish undetected.

If you suspect mold in your home, early intervention is critical. At Octagon Cleaning & Restoration Services, we excel in identifying and addressing mold issues, ensuring your property is safe and sound. Contact us today to combat mold damage and protect your space from further harm.

When Does Mold Grow?

Mold can grow indoors whenever there is moisture, organic materials, and a comfortable temperature. Mold growth is a concern after a water damage loss, so it’s important to dry all building materials promptly and thoroughly. It can also occur in areas of your property where humidity and moisture can accumulate, kitchens, bathrooms, and laundry rooms.

Because mold spores can be disturbed easily, it’s best to consult a professional for mold removal and remediation. Octagon Cleaning & Restoration’s ACAC and IICRC-certified specialists serve Cheshire, Hillsborough, Merrimack, Strafford, Sullivan, and Rockingham counties. They know how to remove the mold safely and effectively and prevent it from returning.

Where Should I Look for Mold Growth?

In areas of your property prone to moisture issues, it’s a good idea to look for signs of mold growth or moisture problems regularly. We often find mold growth on walls where moisture can become trapped or water lines are located. This can be behind furniture or cabinets, behind the refrigerator or washing machine, and under the sink. Mold can also grow in attics and basements/crawl spaces when there is not enough air circulation, so it’s a good idea to check those areas regularly. If you see signs of mold growth or a moisture problem, call the Octagon Cleaning & Restoration team. We are trained and have the tools to check for moisture throughout your property.

Frequently Asked Questions

Does mold still need to be removed if it isn't black mold?

There’s a lot of misinformation surrounding mold, especially black mold. Some people have falsely been told that black mold is the only dangerous mold. This is untrue. Any mold has the potential to be dangerous for your health and your property. Because of this, all mold problems should be promptly addressed by professionals.

Is professional mold removal covered by my insurance?

Every insurance policy is different. Professional mold removal is most likely to be covered by insurance when it is caused by sudden, covered events like burst pipes. Mold caused by neglect is typically not covered by policies.

Check your policy to learn more about your coverage.

If you are covered, we will coordinate with your insurance provider to ensure a seamless mold remediation process for you.

Can I clean up mold myself?

Small patches of mold on non-porous surfaces, such as tile, can sometimes be cleaned with household products and proper safety gear. However, larger infestations, mold on porous materials (like drywall or insulation), or hidden mold require professional remediation. DIY efforts often overlook the root cause, and improper cleaning methods can exacerbate the problem or spread spores to other areas.

Why is professional mold remediation necessary?

Professional mold remediation involves more than just cleaning visible mold. Mold spores must be physically removed, and the area must be properly contained to prevent cross-contamination. Bleach and fogging treatments may kill mold, but do not remove health risks or prevent regrowth. At Octagon Cleaning & Restoration, we utilize IICRC-certified techniques and equipment to safely remove mold, ensuring your property is safe.

How long does mold remediation take?

Most mold remediation jobs take 1–5 days, depending on the severity, size of the affected area, and whether demolition or reconstruction is needed. We’ll provide a detailed project timeline so you know what to expect.

Will mold come back after remediation?

remediation process includes identifying and fixing the source of moisture—whether it’s a leak, poor ventilation, or high humidity—to prevent future growth.

What are the signs of mold in my home?

Common signs include musty or earthy odors, visible mold growth (often black, green, or white spots), bubbling paint, warped walls, and increased allergy or respiratory symptoms. You may also notice condensation or moisture issues in specific areas. Mold can also grow behind walls or under flooring, so if you suspect a problem, a professional inspection is recommended.

Does mold always have a smell?

Often, yes. Mold tends to produce a distinct musty odor. However, not all mold has a noticeable smell, and some infestations can be completely hidden. If you notice a persistent musty smell and can’t locate the source, a mold inspection is a smart next step.

Is all mold dangerous?

While not all mold is toxic, any mold growth can impact indoor air quality and pose health risks, especially for those with allergies, asthma, or compromised immune systems. Black mold (Stachybotrys chartarum) is particularly concerning, but all mold should be assessed and remediated professionally to protect your health and prevent further damage.

What causes mold to grow indoors?

Mold needs moisture, warmth, and organic material to grow. Common causes include:

Leaking pipes or appliances
Roof or window leaks
Flooding or water damage
High humidity or condensation
Poor ventilation in areas like bathrooms or basements. Controlling moisture is the key to preventing mold.

Do you offer post-remediation mold testing?

No, Octagon Cleaning & Restoration does not conduct post-remediation testing, as it would be a conflict of interest. We recommend independent, third-party environmental testing companies to verify that mold has been completely removed and the affected areas meet industry air quality standards.

How do professionals test for mold in a home?

Certified mold inspectors use a combination of tools and techniques:

Moisture meters to detect hidden water sources
Air sampling and surface swabs to test for mold spores
Visual inspections in hard-to-reach areas (like crawlspaces and attics). This comprehensive approach helps confirm both the presence and extent of mold contamination.

Will mold come back after remediation?

If the underlying moisture problem isn’t fixed, mold can return. Our mold remediation process includes identifying and addressing the source of moisture—whether it’s a leak, high humidity, or condensation—to prevent future growth.
