The short answer
Identify the Mold Type
Before you start, figure out what kind of mold you are dealing with. Common household molds include Cladosporium, Aspergillus, and Stachybotrys (black mold). Each may require different handling, but the removal process is similar for most. If you see a small patch, you might handle it yourself. If the mold covers more than a few square feet, professional help is wise.
Check the material behind the mold. Drywall and wood are porous, meaning mold can penetrate deep. Non-porous surfaces like tile or glass are easier to clean. If the drywall is soft or crumbling, it likely needs replacement. In this area, mold often appears after seasonal moisture seeps in, so look for water stains or leaks nearby.
- Look for the source of moisture: a leak, condensation, or flooding.
- Check if the mold is on the surface or has penetrated the material.
- Note the size of the affected area: small patches are manageable, large ones need pros.
- Consider getting a mold test kit if you are unsure about the type.
- If anyone in your home has asthma or allergies, be extra cautious.
Safety Precautions First
Mold removal can release spores into the air, which is harmful to breathe. Always wear an N95 respirator mask, goggles, and gloves. Open windows to ventilate the area, but close doors to other rooms to prevent spores from spreading. If you feel unwell, see a doctor. Never mix cleaning products, as toxic fumes can result.
For small areas, you can use a mixture of water and mild detergent. Avoid bleach on porous surfaces because it may not penetrate and can leave toxins behind. For larger areas, the pros use specialized equipment like HEPA vacuums and air scrubbers. They also know how to contain the area to prevent cross-contamination.
- Wear an N95 mask, safety goggles, and rubber gloves.
- Ventilate the space by opening windows and using fans.
- Seal off the room with plastic sheeting if possible.
- Remove and discard any porous materials that are heavily moldy.
- Do not use a regular vacuum; it can blow spores into the air.
Clean Small Patches Yourself
For mold patches smaller than about three feet by three feet, you can often clean them yourself. Use a sponge or cloth dipped in a solution of water and dish soap. Gently scrub the moldy area, then wipe with a clean, damp cloth. Dry the area thoroughly with a fan or dehumidifier. After cleaning, apply a mold-inhibiting primer or paint if needed.
Avoid using bleach on wood or drywall because it does not soak in and can leave moisture behind. Instead, use a commercial mold remover that is safe for the material. Always test a small, hidden spot first. If the mold returns quickly or the area is large, that signals a deeper problem that needs professional attention.
When to Call the Pros
If the mold covers a large area, is on drywall, or has spread into the wall cavity, you need professional help. The pros have the training and equipment to remove mold safely and address the underlying moisture issue. They can also test for hidden mold behind walls. In this dry climate, summer storms can bring sudden moisture, so act quickly.
The pros will typically isolate the area, remove contaminated materials, clean and treat the surfaces, and then dry everything thoroughly. They may also apply antimicrobial coatings. The cost depends on the extent of damage, the materials involved, and the size of the area. It is often in the hundreds to thousands of dollars range, but each situation is different.
Prevent Future Mold Growth
Mold needs moisture to grow, so the key is to control humidity and fix leaks. Use exhaust fans in bathrooms and kitchens, and run a dehumidifier in damp areas. Keep an eye on windows and roofs after heavy rain. Fix any plumbing leaks promptly. Ensure proper ventilation in your home, especially in closets and corners.
Regularly inspect areas prone to moisture, like under sinks and around air conditioners. If you see condensation, wipe it up and consider insulation. If you have a flood, dry out your home within 24 to 48 hours to prevent mold. If you are unsure about a spot, a mold professional can test and advise. Policies vary, and your insurer decides what is covered.
Water damage does not wait
Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

Can I just paint over mold?
Painting over mold is not a solution. Mold will continue to grow underneath and eventually show through. You must remove the mold completely and fix the moisture problem first. If you paint without cleaning, the mold can spread and cause health issues.
Is black mold more dangerous than other mold?
Black mold, or Stachybotrys, can produce toxins that are harmful, but any mold can cause allergies and respiratory problems. The color is not necessarily an indicator of toxicity. All mold should be removed promptly. If you have health concerns, see a doctor.
How long does mold removal take?
The time depends on the size and severity of the mold. Small patches may take a few hours, while larger areas could take days. The pros will assess and give an estimate. The process includes cleaning, drying, and possibly replacing materials.
