Don’t Let Mold and Mildew Turn Your Deck Into a Health Hazard – Here’s What You Need to Know

Your deck should be a place of relaxation and entertainment, not a breeding ground for dangerous microorganisms. Unfortunately, many homeowners underestimate the serious health risks that mold and mildew pose when they take hold of outdoor wooden surfaces. When mold grows on deck, it may cause problems including serious health hazards, making professional remediation not just a cosmetic concern, but a critical safety issue.

Understanding the Health Risks of Deck Mold and Mildew

Mold and mildew aren’t just unsightly – they’re potentially dangerous to your family’s health. For some people, mold can cause a stuffy nose, sore throat, coughing or wheezing, burning eyes, or skin rash. People with asthma or who are allergic to mold may have severe reactions. The risks extend beyond respiratory issues, as immune-compromised people and people with chronic lung disease may get infections in their lungs from mold.

The physical dangers are equally concerning. When mold forms on wood it makes the surface slippery. Walking on such a slippery surface is a serious health hazard that may cause injury or fractures. This is most dangerous if the mold grows on staircases. Additionally, when molds grow, the spores easily spread into the air and cause air pollution in poorly ventilated areas. When inhaled, these spores can cause respiratory complications such as chest congestion and difficulty in breathing.

Particularly vulnerable individuals include people with allergies, who may be more sensitive to molds; people with immune suppression or underlying lung disease, who are at higher risk of fungal infections; individuals with chronic respiratory diseases like asthma or chronic obstructive pulmonary disease (COPD), who may have trouble breathing when exposed to mold.

Identifying Mold and Mildew on Your Deck

Early identification is crucial for preventing extensive damage and health risks. Mold appears as fuzzy, dark spots that penetrate wood, usually black, dark gray, or green. Mildew appears as flat, powdery white or gray spots that are easier to wipe off than mold. Black mold, or Stachybotrys chartarum, is a toxic fungus that thrives in dark, damp environments. It’s usually dark green or black in color and often carries a strong musty odor.

The conditions that promote mold growth are unfortunately common on many decks. Whether your deck is made of wood, composite, or PVC, mold thrives in damp, shaded areas with poor airflow. Leaves, twigs, branches, and debris are potential mold contributors. When they pile on the surface, they form a conducive breeding ground for mold. To prevent debris from building up, clean the deck surface frequently.

The Structural Damage Beyond Health Concerns

While health risks are the primary concern, mold and mildew also pose significant threats to your deck’s structural integrity. Left untreated, it can lead to rot, stains, and even structural damage. The damage can be superficial or can go as far as to cause major structural damage. Mold and mildew on decks will also eat through and deteriorate deck stains that are there to protect the wood.

Beyond health concerns, black mold poses significant risks to the structural integrity of your wood deck. The fungus feeds on organic materials found in wood fibers, leading to decay over time. This can weaken the wooden planks and support structures beneath them. Left unchecked; this deterioration compromises the safety of your deck by making it unstable underfoot.

When to Call Professional Remediation Services

While minor mold issues might seem manageable, there are clear indicators when professional intervention becomes necessary. If the affected area covers more than 10 square feet, it’s generally advisable to seek expert help due to the potential health risks and extensive labor involved. Additionally, if you’ve tried DIY cleaning methods without success or notice that mold returns quickly after treatment, it indicates a deeper issue requiring specialized attention.

Professional remediation becomes essential when individuals with respiratory issues, allergies, or weakened immune systems should avoid handling mold cleanup themselves. Also, consider calling professionals if you detect structural damage such as wood rot or warping caused by prolonged moisture exposure.

The EPA provides clear guidance on professional remediation: If there has been a lot of water damage, and/or mold growth covers more than 10 square feet, consult EPA guide Mold Remediation in Schools and Commercial Buildings. If you choose to hire a contractor (or other professional service provider) to do the cleanup, make sure the contractor has experience cleaning up mold. Check references and ask the contractor to follow the recommendations in EPA guide Mold Remediation in Schools and Commercial Buildings.

Prevention: Your First Line of Defense

The most effective approach to deck mold and mildew is prevention. Apply a deck stain or sealer: deck finishes seal over your deck boards to keep moisture out. That’s a big deterrent for fungi and plants, which need damp environments to survive. Clean your deck regularly: fungi like mold and mildew feed on organic matter – and a deck covered in leaves, pine needles and dirt is like a buffet table for these deck pests.

Regular maintenance is crucial. Most wooden decks should be cleaned and re-stained every 1-2 years as maintenance. Regular cleaning with a deck cleaner will help ensure that mold/mildew does not infiltrate your deck in any form. Additionally, the key element to preventing most mold and mildew is to control dampness. Stopping water leaks, ensuring perfect air-flow in attics, maintaining crawlspaces, and drying/redirecting water away from your house foundation are the most effective defenses.

Taking Action for Your Family’s Safety

Mold and mildew on decks represent more than just a maintenance issue – they’re a genuine health and safety concern that requires prompt, professional attention. Mold can destroy your deck if not controlled. It also has the potential to cause serious health hazards and illnesses. With that in mind, ensure you remove molds whenever you notice any growth.

Don’t wait until the problem becomes overwhelming. Early intervention by qualified professionals can save you from extensive health risks, structural damage, and costly repairs. When dealing with deck mold and mildew, remember that your family’s health and safety should always be the top priority, making professional remediation services not just an option, but often a necessity.
