It is important to learn how to check for mold growth in your home. Even before you begin projects like repainting, it's always important to check whether there is mold growth inside the walls to avoid incurring additional costs of tearing the wall down once you've already repainted it. However, if you are not sure about how you can detect mold inside your home, you can call a professional from a mold-removal service company, such as Safe-Way Waterproofing, to do the inspections. The following are the ways to check for mold growth inside the walls of your home.

Borescopes

These are the most intrusive but consistent tools that are used to test for molds inside your walls. A borescope has two parts: a boring instrument (bore) and camera (scope). You can use the borescope to bore in the wall where you are suspecting a mold growth and then use its flexible camera to inspect how your walls look from the inside. The tool enables you to check the extent of the mold growth without having to tear down your walls. This, in turn, gives you an easy time when figuring out the steps to take when dealing with the mold problem.

Discoloration, musty, allergies, and smell

At times, you don't need high-tech instruments to check for mold inside of walls. A human sense of is another way of testing for mold—especially if the mold is its advanced stage. When you suspect that a particular area has a mold infestation, start by checking for any signs of discoloration. Moisture does not relate well with drywall, and this means that minor moisture spots can cause a significant imprint.

Smell is another way that can help you to check for mold. You probably don't know what mold smells like. However, it wouldn't smell like the rest of your house. You can sniff around the areas you suspect and look out for a musty smell, which resembles the smell of an old building or basement. If you find some areas in your house with such kind of smell, then that's an indication of mold growth inside the walls.  

Also, a person who is allergic to mold and knows that they are having signs of allergic reaction to mold is an indication of mold inside the walls, and they should have it inspected by a person from mold-removal services.

Moisture meters

Professionals from mold-removal services mostly use these tools, and they are a bit costly for an ordinary person. Mold meters come in two types:

• One that requires direct contact with the wall to check for signs of moisture levels inside the walls

• The other relies on radio-frequency signals to check for moisture signs without having a direct contact with the wall

Both of these types are straightforward to use, and they can help you to know whether there is enough moisture to promote mold growth.
