The crawlspace in this photo looks brand new. The vapor barrier is secured high on the walls. The piping and wiring is secured evenly against the bottom of the floor joists. In the foreground it looks like some insulation might be only partly secured to it's pipe.

Research & Writing Assignment:

Looking at the diagram Proper Crawlspace Vapor Barrier. This diagram is especially good for showing what kinds of precautions need to be taken and why. Such as the Insect Resistant furring or lapped vapor retarder sheets. The barrier should be taped between sheets and sealed to the wall with caulk.

Inspection & Writing Assignment:

Pictured is the opening to a crawlspace under a manufactured home. We can see pvc drain pipes and supply pipes. Also visible are the piers and a subflooring insulation. In the top left of the photo there is some loose wiring laying in the dirt. This can be a hazard to the inspector while under the crawl space so caution should be taken. You would also want to report the loose wires.

Research & Writing Assignment:

Crawlspaces are usually dark and in the majority of cases, damp. This tends to promote both virus and bacterial growth so always take precautions when inspecting crawlspaces.It is imperative that crawlspaces be properly ventilated if one wants to avoid virus and bacterial growth in crawlspaces. Dirt crawlspaces will often harbor pests such as termites, ants, rodents, scorpions, snakes etc.

Research & Writing Assignment:

I learned that a downspout extension should be at least 4-6 feet away from the foundation wall. If not, roof water drainage will naturally seep back toward the foundation and wick through into the underground structure or crawlspace. This can lead to excess moisture promoting microbial growth.

Research & Writing Assignment:

Despite crawlspace venting being a widely accepted norm, there are cases where venting can do more harm than good. In humid climates allowing air to pass into the crawlspace from the exterior can result in water condensation build up instead of drying out the foundation as intended.

Inspection & Writing Assignment:

This is an example of a crawlspace with moisture and drainage problems, there is a vapor barrier but its installed improperly also there are signs on the stem wall that there has been standing water, I recommend drainage improvements on the exterior and proper installation of the vapor barrier.

Inspection & Writing Assignment:

This was a 2x4 joist that was observed to be directly installed in a foundation wall. At the time of the inspection this joist had almost completely disintegrated, apparently from termite damage. Client was informed that this provides an opening in the foundation wall that could weaken the foundation and potentially allow moisture penetration into and through the foundation.

Research & Writing Assignment:

I read the article on asbestos cement siding. Because the area I work in is primarily a newer development area (1980s+) I have never actually seen asbestos cement siding installed around here, but I have seen it in some of the other counties around here. I learned that like most asbestos products, the siding is ok unless it is made into a dust. It is also quite fragile and difficult to replace but is otherwise long lasting and extremely fire resistant.

Also this floor of the crawlspace has no plastic neither do the walls. This could be the reason that there is water intrusion. This crawlspace needs to sealed immediately.

Research & Writing Assignment:

In this article I read about crawl spaces. Crawlspaces are very hazardous and dangerous places where inspectors should be very careful. There could be rodants such as rats snakes etc. Very dangerous part about crawlspaces are the air polluntants such as mold which can give you health problems with your lungs.

https://www.nachi.org/crawlspace-hazards-inspection.htm

The article I chose is entitled: Crawlspace Hazards and Inspection.

I learned that crawlspaces are subject to mold, fungus, and even the hantavirus which is carried by rodents. Wearing appropriate PPE including breathing protection is a good idea. Older homes also have asbestos insulation which can pose dangers.
