The short answer
First Stop the Moisture
Mold needs moisture to grow, so the first step is to find and stop the water source. Check for leaks from pipes, the roof, or windows. If you live in Rockwall, spring storms can drive water through cracks, so inspect the exterior walls too. Look for stains, peeling paint, or a musty smell, and feel the walls for damp spots.
Turn off the water supply if a pipe is leaking, and dry the area as much as possible with towels or a fan. For hidden leaks, a leak detection service can pinpoint the problem without tearing open the wall. Also check caulking around windows and doors, and inspect the attic for roof leaks.

Clean Small Mold Patches
For mold covering less than about 10 square feet, you can often clean it yourself. Use a solution of one part bleach to three parts water, or a commercial mold cleaner. Apply it with a sponge or cloth, and scrub gently to avoid damaging the paint. If the wall is textured, use a soft brush to reach into the pores.
Wear rubber gloves, safety goggles, and an N95 mask to avoid breathing spores. Open windows or use a fan to ventilate the area while you work. After cleaning, dry the wall completely with a fan or dehumidifier. If the mold returns, the moisture problem is still active.
When to Call a Pro
If the mold covers a large area, or if the drywall is soft, crumbling, or deeply stained, the wall may need to be cut out and replaced. In that case, local water damage pros can assess the extent and often handle the removal and drying. They can also check for hidden moisture in the wall cavity, which is a common cause of recurring mold.
For a thorough evaluation, a water damage inspection or moisture mapping service can show how far the water has spread. You might also consider having a mold professional test the air quality if you are concerned about health effects.
Prevent Mold from Coming Back
Once the mold is gone, keep the wall dry. Fix any leaks, improve ventilation in bathrooms and kitchens, and use a dehumidifier in humid months. In a humid subtropical climate, controlling indoor humidity is key. Aim to keep indoor humidity below 50 percent.
Seal gaps around pipes and windows, and wipe down wet surfaces. If you notice condensation on walls, that is a sign that humidity is too high. Keeping the area dry is the right way to prevent mold from returning.
Safety and Health Notes
Mold can cause allergic reactions or breathing problems. If you feel unwell while cleaning, stop and see a doctor. Never mix bleach with ammonia or other cleaners, as that can create toxic fumes. Also avoid using bleach on porous surfaces like wood, as it may not penetrate deeply.
For large mold problems, especially after flooding or a burst pipe, do not attempt to clean everything yourself. Flood damage cleanup often involves removing soaked drywall and drying the structure, which is right to leave to the pros. They have the equipment to dry wall cavities thoroughly.

Can I just paint over mold?
Painting over mold does not kill it. The mold can continue to grow underneath and eventually show through the paint. You need to remove the mold and address the moisture source first, then repaint.
How do I know if the mold is dangerous?
Any mold can trigger allergies or asthma symptoms. If you see a small patch, you can clean it with precautions. For larger areas or if you have health concerns, see a doctor and consider professional help.
Will my insurance cover mold removal?
Policies vary, and your insurer decides what is covered. Some policies exclude mold, while others cover it if it results from a covered water loss. Check your policy and talk to your insurer to understand your coverage.
