water leak damaged homes - the restoration

Leaky roofing and leaky pipes can cause a lot of damage to a house. If you don't act quickly, these two problems can result in major repairs that can get quite costly and complicated. My blog will show you how to identify these problem areas and how to judge the severity of the damage sustained. Having restored a few homes over the years before selling them, I have a lot of experience working with water damaged homes. I hope that all of the information that I have included here in this blog will help you get through the process with fewer issues.

How To Clean Mold From A Concrete Patio

by Paul Burton

If you notice green, orange, or black patches on your concrete patio along with a musty smell, it is probably mold. You want to get rid of mold right away to prevent allergies and other health hazards. You should be able to clean small patches of mold yourself with the right tools. Here are some tips to clean mold from concrete patios.

Prepare to Work

For this project, you need:

  • latex gloves
  • face mask
  • garden hose
  • pressure washer
  • wet/dry vacuum
  • mini-vac
  • bucket
  • stiff-bristle brush
  • bleach
  • borate-based detergent
  • spray bottle 
  • white distilled vinegar
  • baking soda
  • steam cleaner

Rinse the patio floor with a pressure washer or garden hose to remove surface dirt. Use a wet/dry vacuum to suck up the water. Clean cracks or crevices with a mini-vacuum.

Clean Mold with Bleach

Bleach works on concrete because it reaches the pores under the surface. Mix a cup of bleach with a gallon of warm water in a bucket. Diluting the bleach helps to avoid killing vegetation.

You still want to avoid as much runoff as possible, so apply a small amount of the mixture directly on the mold. Let it sit several minutes to loosen the mold. 

Coat the brush with the mixture, and scrub the area in a circular motion. Scrub until the mold starts to vanish. Rinse the area thoroughly with a garden hose, and let the area dry. Repeat the process, if needed.

To prevent mold spores from returning, make a mixture from a cup of borate-based detergent and warm water. Apply it to the concrete, and let it dry naturally.

Blast the Mold with Steam

A steam cleaner is a safe way to clean mold from a concrete patio. Wear a long-sleeve shirt, pants, and closed-toed shoes when you operate a steam cleaner to avoid skin burns.

Pour the water in the steam cleaner and let it warm up. Hold the nozzle about a foot away from the mold. Break the mold with a blast of hot steam, then rinse with a hose.

Try White Distilled Vinegar or Baking Soda

Fill a large spray bottle with warm water. Spray a thin mist of water on the mold, and add a moderate amount of baking soda. Pour on a little vinegar, if desired. Let the mixture stand several minutes, scrub it with the brush, but don't rinse.

You can also try vinegar by itself. Mix two cups of hot water and one cup of vinegar in a spray bottle. Squirt a small amount on the area, let it soak several minutes, and scrub the area. Don't rinse.

Your patio will be enjoyable once the mold is gone. If you don't trust your skill, there are large patches of mold, or the concrete is seriously water-damaged, contact a mold remediation and repair service. To find out more, speak with a business like Colfax Corporation.
