We know that mold is caused by a combination of moisture and darkness and can be hidden in the walls and floors of any home. It not only thrives in already existing homes, but it can be found in new construction too.

How Can Mold Affect New Construction?

Mold thrives indoors and out, and, if it proliferates, it can slow construction and increase costs by the replacement of affected materials as well as costs of remediation. Climate and location factor into mold growth and some construction sites are more simply more susceptible as a result of those factors. Prevention is key, and measures undertaken before and during construction can go a long way in keeping you and your construction site mold-free.

Choose Your Site Wisely

A location with a high water table will prevent moisture from entering into a new home’s foundation. Also, the ground around the foundation should be drained or graded to redirect any water away from the construction.

Inspecting And Storing Construction Materials

Make sure to check all materials before you start using them—even if you live in a dry climate—to determine if they were handled and transported properly. Manufacturers usually wrap materials with moisture resistant protection, but sometimes it still gets through. Most suppliers will offer a window of time for inspection, and possible rejection, of materials.

Once you’ve proved your materials are safe and moisture free, store them in a dry, covered place that has a roof and is a few feet off the ground. Wrap the materials with plastic sheets, but not too tightly, as moisture can build over time. Your best bet is also to limit storage time, so order your materials right before they are going to be used.

How To Handle Moisture & Mold On Construction Materials

If your materials do get wet, dry them before construction begins. Use a moisture meter to tell you if they are ready to use—wood shouldn’t contain more than 19% moisture, and engineering materials should be at about 4%. If there are wet weather or time limitations, you may need commercial dehumidification equipment to help your materials along.

Sometimes, there’s too much mold, even with on new materials, to handle yourself. Calling a mold remediation specialist may be the only possible solution. If the mold remains or reappears during the construction process, don’t hesitate to contact a professional for help.
