The short answer

Finding Hidden Moisture

Infrared cameras work by detecting surface temperature variations. When water evaporates, it cools the surface, so damp spots show up as cooler patches on the thermal image. This lets pros scan large areas quickly and pinpoint problem zones that would otherwise be invisible to the naked eye.

For example, a slow leak behind a shower wall or under a kitchen sink might not show any visible signs until serious damage occurs. With an infrared camera, the pros can identify the exact location of the moisture without opening up your walls. That saves time and reduces unnecessary demolition.

  • Scan walls, floors, and ceilings for temperature anomalies
  • Locate water intrusion behind tile, drywall, and wood
  • Check for moisture around windows, doors, and pipes
  • Identify areas where drying is needed before mold can start
  • Document findings for your insurer if needed. Policies vary, and your insurer decides what is covered.

Tracking Drying Progress

Once drying equipment is set up, infrared cameras help pros monitor how well the materials are drying. As moisture leaves, the temperature patterns change, showing whether the area is returning to normal. This allows them to adjust the number of air movers or dehumidifiers as needed.

Without this tool, you might think a surface is dry just because it feels dry to the touch. But moisture can linger deep inside studs or subfloors. Infrared imaging gives a more accurate picture, so the pros can confirm that the drying is complete and reduce the risk of hidden rot or mold.

Detecting Mold Growth

Infrared cameras can also hint at potential mold growth. Mold often develops in areas that stay damp for a while, like behind a refrigerator or under a leaky roof. The camera can reveal these damp spots, allowing a mold professional to inspect further and take samples if needed.

Keep in mind that infrared alone cannot confirm mold. It only shows moisture patterns. If you suspect mold, a qualified mold professional should do a thorough inspection. They may use moisture meters and air sampling to determine the type and extent of any growth.

  • Reveal damp areas where mold might thrive
  • Help target mold inspection and sampling
  • Show moisture behind baseboards and trim
  • Identify wet insulation in attics and crawlspaces
  • Assist in finding roof leaks before they spread

Inspecting After a Flood

After a flood or major water leak, infrared cameras are especially useful. Floodwater can soak into materials unevenly, leaving hidden pockets of moisture. The pros can scan your entire home to map out all the affected areas, which helps them decide what needs to be removed and what can be saved.

In humid climates, where natural drying can be slow, this step is especially important. By identifying all moisture sources, the pros can set up the right drying strategy. This might include removing wet carpet, padding, or drywall that cannot be salvaged.

Preventing Future Damage

Infrared cameras are also used for routine checks to catch problems early. For example, a pro might scan around your windows, doors, or roof to spot any areas where water could be getting in. This can help you fix small issues before they turn into major repairs.

Consider having a water damage inspection done after heavy storms or if you notice musty odors. The pros can use infrared imaging to give you a clearer picture of your home's condition. Early detection often means less damage and fewer costs.

Frequently asked questions

Can infrared cameras see through walls?

No, infrared cameras cannot see through walls. They measure surface temperature, so they only show temperature differences on the surface. However, moisture behind a wall can cool the surface, making it visible. This helps pros locate hidden leaks without cutting into the wall.

How accurate are infrared readings?

Infrared readings are quite accurate for detecting temperature differences, but they are not a direct moisture measurement. Factors like sunlight, wind, and room temperature can affect readings. Pros often combine infrared with moisture meters to confirm the exact moisture content in materials.

Should I buy my own infrared camera?

Buying an infrared camera can be expensive, and using it correctly takes training. Without experience, you might misinterpret the images and miss important clues. For a thorough assessment, it is wiser to let the pros use their equipment. They know how to read the images and what to do next.
