Even in the cleanest NYC homes and offices, mold can thrive in hidden spaces. Routine cleaning keeps surfaces spotless, but many areas vulnerable to mold are rarely touched—even by professional cleaners.
At Choice Mold Removal NYC, we’ve seen mold hiding in places most people never think to check. Here are the most overlooked mold hotspots and how to prevent them from becoming long-term health hazards.
1. Behind and Beneath Appliances
Refrigerators, dishwashers, and washing machines often trap moisture behind them. Leaks, condensation, and food spills can create the perfect breeding ground for mold.
Tip: Pull appliances away from the wall once a season and inspect for moisture or stains.
2. Inside Air Conditioners and HVAC Systems
Mold loves dark, damp areas with limited airflow—making AC units and ducts ideal hiding places. If there’s a musty smell when your AC runs, mold could be circulating in your air.
Tip: Clean and inspect filters regularly. Schedule annual HVAC cleanings with mold-safe solutions.
3. Window Sills and Tracks
Condensation builds up quickly on NYC windows, especially in older buildings. If not wiped down, this moisture collects in tracks and corners, feeding mold growth.
Tip: Dry your windows daily in winter or after rain. Apply a mold-resistant sealant to wood frames.
4. Underneath Sinks and Inside Cabinets
Leaks or drips under sinks often go unnoticed until damage is visible. Mold can grow in the wood or particleboard of the cabinet base.
Tip: Use under-sink mats, check monthly for moisture, and fix plumbing issues immediately.
5. Around Toilet Bases and Bathtubs
Even tiny gaps in caulking or tiles can allow water to seep underneath, leading to mold growth behind the walls or under the flooring.
Tip: Reseal tiles and caulking annually. Inspect for soft flooring or discoloration around the toilet.
6. Behind Furniture on Exterior Walls
Couches, wardrobes, and beds placed against exterior-facing walls block airflow. Moisture condenses on cold walls and gets trapped behind furniture.
Tip: Leave a few inches between furniture and the wall to allow airflow. Rotate items regularly.
