Research & Writing Assignment:

This article talks about using an infrared camera in conjunction with a moisture meter. You can use a thermal imaging camera to find water intrusion, cold, or hot air in places they are not suppose to be. You can use the camera to determine if you are lacking insulation in walls and ceilings. https://www.nachi.org/ir-cameras-inspecting-moisture.htm

Inspection & Writing Assignment:

This photo represents the lack of insulation and poor roofing. This issue is one of the first steps of moisture intrusion through the roof failure and the failure of the insulation due to the roof failure. Ensuring that the roofing is correctly installed will help lower the possibility of moisture intrusion.

Inspection & Writing Assignment:

I chose to write this essay on proper sealing around window installation. As you can tell from the inspection i did, the windows had proper caulking to seal all the window perimeter and around all screws. Therefore this window installation was done correctly to code.

Research & Writing Assignment:

This portion of my inspection is being done on proper vapor barriers in the crawlspace. A 6 mil vapor barrier should be installed on the ground and walls. To insure that moisture doesnt get trapped in the crawlspace which would lead to moisture issues in the homes structure and dehumidifier is also recommended.

Research & Writing Assignment:

I have read the inspection article titled Condensation in Double-Paned Windows located at
https://www.nachi.org/condensation-double-paned-windows.htm
What I have learned:
Double paned windows are typically composed of a layer of gas sandwiched between 2 panes of glass. The edges are sealed to hold in the gas and keep moisture and pollutants out. As the window goes through heating and cooling cycles, the seals are stressed eventually leading to failure of the seal. A failed seal will result in the presence of condensation between the panes and reduced efficiency.

Concrete slab cracking. Most common concrete slabs are purposely saw cut. So they only split along the actual saw cut line. Most foundation problems occur when the walls dont have the proper pressure and gravel installed. As problems increase. The more expensive it will be to fix the problem.

Inspection & Writing Assignment:

At the time of this inspection, I observed a large amount of water penetration damage in the secondary bathroom. The attached image shows where metal lath(a meterial used to reinforce Portland cement mortor) has oxidized and deteriorated within the corner of the shown window. This is a defect and correction is needed.

"IR Cameras: Inspecting for Moisture Intrusion"

Thermal imaging cameras provide a visual aid for home inspectors when searching for moisture intrusion. Dark spots within the image show areas that might have moisture present as moisture is typically cooler then building materials. Thermal imaging should always be backed up by a moisture meter to confirm the existence of intrusion.

Inspection & Writing Assignment:

There is evidence of excessive moisture present in the crawlspace. The flooring insulation "dripping" is evidence of increased humidity levels in the crawl space. There is no installed vapor barrier in the crawlspace. Increased humidity in a crawlspace promotes the growth of wood destroying organisms and mold as well as potentially damaging interior floor coverings.

As seen in the above picture there is negative slope toward the crawl space of the home. This will allow water intrusion under the home and more sure to permeate through the structure. It is recommended this be evaluated and repaired as needed by qualified contractor.

Research & Writing Assignment:

Bathroom Ventilation Ducts and Fans
The primary purpose and function of a bathroom exhaust fan is moisture removal. The secondary purpose is for oder removal. Exhaust fans or a functioning window should be installed in all bathrooms. Although, a functioning window can serve the function and meets the code requirements they are not often opened and therefore do not remove moisture or odors. Bathroom exhaust fans should be ducted to the buildings exterior and not into the buildings attic space. Duct termination into the buildings attic or crawl space only moves the moisture problem to a building area that is not readily inspected.

Inspection & Writing Assignment:

The roof covering in the above photo is evidence of a failing roof. This could allow moisture into the attic structure of the home. More than 20% humidity in the structure members would be conducive to deterioration of said structure. Recommend evaluation by a qualified contractor.
