How to Prevent Mold in Older Pittsburgh Homes

Introduction

Pittsburgh’s historic homes have a charm and character all their own, but they also come with unique challenges. One of the most common issues homeowners face is mold growth, thanks to the city’s humid summers, older construction, and frequent rain. Mold isn’t just unsightly—it’s a serious health risk that can cause respiratory issues and allergies.

Fortunately, with a few proactive steps, you can protect your home from mold growth. Here’s what you need to know about keeping your older Pittsburgh home safe and mold-free.

1. Address Common Problem Areas

Older homes are especially vulnerable to mold because of aging materials and outdated building practices. Here are the areas to focus on:

Basements and Crawl Spaces:
These spaces often have high humidity and poor drainage, creating the perfect environment for mold.
Tip: Install a dehumidifier and ensure proper grading around your foundation to divert water away from the house.
Bathrooms and Kitchens:
Without adequate ventilation, moisture from showers, sinks, and cooking can accumulate and lead to mold.
Tip: Use exhaust fans during and after cooking or showering, and clean grout lines regularly.
Attics and Roofs:
Leaky roofs or poor insulation can trap moisture in the attic, encouraging mold growth.
Tip: Inspect your roof annually for leaks and ensure your attic is properly ventilated.

2. Control Humidity Levels

Pittsburgh’s climate can make it difficult to keep humidity in check, especially during the summer. Mold thrives in environments with humidity levels above 60%.

Invest in Dehumidifiers:
Place dehumidifiers in areas prone to dampness, like basements and bathrooms.
Use Air Conditioners:
Air conditioning helps regulate indoor humidity while keeping your home cool and comfortable.
Monitor Humidity with Hygrometers:
A simple hygrometer can help you track humidity levels in different parts of your home.

3. Fix Leaks and Water Intrusion Quickly

Older homes often have plumbing issues or foundation cracks that allow water to seep in, creating prime conditions for mold.

Inspect Your Plumbing Regularly:
Look for leaks under sinks, around toilets, and near water heaters. Fix any issues immediately to prevent water damage.
Seal Foundation Cracks:
Small cracks in your foundation can allow water to enter your basement or crawl space. Use waterproof sealant to address minor cracks.
Check Windows and Doors:
Ensure that window and door frames are properly sealed to keep rainwater out.

4. Improve Ventilation

Proper airflow is essential for preventing moisture buildup, especially in older homes with outdated ventilation systems.

Install Exhaust Fans:
Place fans in bathrooms and kitchens to remove excess moisture.
Open Windows:
On dry days, open windows to allow fresh air to circulate through your home.
Clean Air Ducts:
Dirty or clogged ducts can trap moisture and distribute mold spores throughout your home.

5. Schedule Regular Inspections

Mold can grow in hidden areas, such as behind walls or under flooring, making it difficult to spot without professional help.

Why Inspections Matter:
A certified mold inspector can identify potential problem areas and address small issues before they become major problems.
When to Schedule an Inspection:
If your home has experienced water damage, flooding, or persistent musty odors, it’s time to call a professional.

Conclusion

Pittsburgh’s older homes may be more prone to mold, but with proactive measures, you can keep your home safe and healthy. By controlling humidity, addressing leaks, and improving ventilation, you’ll reduce the risk of mold growth significantly. And if you suspect mold in your home, don’t wait—early detection can save you time, money, and stress.
