Have you noticed a dark patch on one side and a streak of green on the other? That could be mold settling into your stone masonry, and it won’t stop there. Florida’s moisture-rich air makes it easy for mold to grow in cracks, pores, and joints. Left unchecked, it can damage the surface, compromise the structure, and lead to expensive repairs. The best part? Mold is much easier to prevent than to fix.
If you’re dealing with mold or want to prevent it, contact the best masonry contractor in Bradenton, FL, for expert advice and services.

Simple Maintenance Steps
1. Keep It Clean
Regularly clean fallen leaves, dirt, and debris. Clean surfaces are more difficult for mold to grow on. A low-pressure washer or a soft-bristle brush can be used to remove dirt without causing any harm to the stones.

2. Inspect After Rain
After a heavy rainfall, take a quick walk around your property. Look for pooling water, damp patches, or signs of runoff near the masonry. Drainage problems often cause moisture buildup and mildew loves moisture.
3. Seal the Stone
Apply a breathable sealer to the surface to keep out excess water while still letting moisture escape. This is key in Florida’s humid weather. Reapply sealant every 2–3 years or as needed.
4. Improve Drainage
If you notice water collecting near walls, patios, or walkways, it’s time to rethink your drainage. French drains, gravel beds, or proper slope grading can help redirect water away from stonework.
5. Trim Nearby Plants
Overgrown bushes or vines trap moisture against stone. Keep plants at a healthy distance. Allowing sunlight to penetrate the masonry naturally dries out surfaces, which makes it more difficult for fungi to grow.

6. Use Mold-Resistant Cleaners
Not every cleaning solution is suitable for stone. Use pH-neutral, masonry-safe mold removers when needed. Avoid bleach because it can damage the natural stones and wear down joints.
7. Repair Cracks or Gaps
Water can enter through even tiny cracks or gaps in mortar or stone. Timely repairs prevent moisture from settling inside. A skilled mason can patch these up without compromising the look of the original structure.
Long-Term Tips to Keep Mold Away
