Lack of ventilation in this crawlspace caused the engineered floor joists to become covered in fungus. The fungus and wood decay in turned started to damage or break down the wood products. The end result were floor joists that were sagging. This sagging created settling cracks and structural damage to the large two story home resting on them. Cost estimates could run into 10's of thousands of dollars.
This home was over 15 years old, and somehow the ceilings got covered up without putting all the insulation in. The thermal image shows areas of exception, that needed to be confirmed for insulation loss. Insulation missing to this degree can cause substantial heat loss and potentially create moisture and mold issues.
The magic disappearing screwdriver tells all. Insect damage was so significant in the main beam of this home that a probe could be easily pushed in. Replacing a main structural beam can cost substantially.
A hot tub above this deck was allowing water to saturate the perimeter band board. This board was a pre-manufactured type and the water was causing it to come apart. Additionally the water was also corroding or damaging the hangers that attached the deck to the home. The deck itself was also not constructed or designed to support the additional load of the hot tub. With all this said, you can imagine the consequences of this thing collapsing with people in the hot tub above.
Soil loss around the concrete support and insect damage was found in this support post for an exterior deck.
No it's not just shadows in the crawlspace. Poor ventilation and a missing vapor barrier had allowed moisture or humid air to damage the sub flooring of the home. The floor was saturated and turned black from moisture damage and fungus growth on the materials.
Obviously the wood framing is not resting completely on the support below. The framing itself was also improperly constructed, The horizontal board was installed as a means of supporting the joists above from downward forces. A practice that was quite common in rural TN years ago, has never been an acceptable way to construct floor framing.
This home was constructed in 2009, and built in a rural TN county that did not enforce building codes. The support girder beam was teetering off the support pier or block below. The entire home was full of poor quality construction practices, and should have never been allowed for occupancy.
This image actually has two issues. The first being that the pipe itself runs upwards, which will not allow for proper slope and drainage. The second issue is the shower connection at the very left of the image. The pipe was actually disconnected and allowing water to leak into the crawlspace below.
This image show where an aged cast iron connection had rotted through and the two sections of pipe were not connected.
Polybutylene Pipe was found in the home during the inspection, and can be confirmed by the markings on the pipe itself. No longer manufactured, several makers of this grey pipe were subject to class action lawsuits paying out millions in damages due to a high failure of pipe connections and deterioration.
Can you find the problem in this photo? At first glance there is no obvious issues. Installing a thermostat above a dimmer can create all sorts of headaches when trying to regulate the homes interior temperature. When dimmers are left on they produce a substantial amount of heat. This heat radiated into the above thermostat, causing a false reading of the actual indoor ambient air temperature.
