This was only one of many signs of moisture penetration in this crawlspace, which was very inadequately ventilated. On top of ventilation issues, the back grade was slopping towards the house, and as you can see, there are signs of efflorescence, actively wet foundation blocks, and past management attempts of sealing in the corners.
Example of water intrusion from a damaged shower pan or poor caulking.
Here is a photo showing a previous leak at a toilet flange. New flange has been installed and area is now dry.
This is the condition of nearly 90% of all attics I inspect that use baseboard heat in the Pacific NW ( Washington state). All attics had lower and upper vents. My first thought is the low vents are blocked, however that isn’t always the case. Any thoughts as to why this happens with such a high degree with baseboard heat and not other sources of heat?
Thanks Allen
Picture of previous water damage on wood floor. Darkened wood is a sign of current or previous water/moisture damage.
Hello everyone,
Here is my photo required for the course.
This photo shows a rest room exhaust fan (spot ventilation). There is a single switch on the wall to turn on the light and exhaust fan. When switch was activated the light came on but the fan did not start. Recommend further investigation by a licenced electrician.
Also noticed the ceiling has staining representative of potential mold. Recommend further investigation by a Professional Mold Technician.
My next step is to go back and review the course material to prepare for the final exam.
I thought this would be interesting for some.
This photo shows a tree growing up through the roof of a shed roof attached to the main house. This area was enclosed as a patio. The tree had a rubber membrane around the trunk that stopped some of the water that flowed down the roof and down the trunk…but…did not stop all of it. The water that did enter the room came down the trunk and watered the tree. As you can see…the rest of the house was falling apart and had been red tagged.
The house burned to the ground later under suspicious circumstances.

Starting the Moisture course now.

This picture shows how water was entering a bedroom window. A window A/C unit was setting in a window ledge and rain would blow under the outer storm window. The window ledge drained down and against the main window ledge and into the wall.
This is a picture of mold that need to be taken care of.
The bathroom has really bad ventilation and the exhaust fan is not adequate for
the room its in. I also think that it dumps in the rafters and not out the roof.
here is a photo showing Moisture intrusion of an exterior basement foundation wall,
Interestingly to note the exterior part of the wall where this leak occurred was only about 1ft below ground level at the back of the home below a stamped concrete patio!
Starting “How to Inspect for Moisture Intrusion” course now…
Excessive moisture, moisture line, and efflorescence in the crawlspace. Moisture meter showed 32% at the substructure.
This picture shows the poor craftsmanship of the contractor that put it in.
This tub is starting to pull away from the wall and that could cause water to leak
behind the wall as well as under the tub. This will cause wood decay and mold to start
growing.
My residence had a brick and vinyl façade. This is a photograph of a weep vent on the front of my house near the garage. The weep vent is free of any debris and appears to be in good working condition
This is a picture of ceiling repair directly below a HVAC supply duct. This may have been caused by inadequate insulation or a compromise of the duct sealing. My concern here is that the repair, which looks DIY, may not have addressed the underlying problem. Further, this is very close to a long span ceiling joist so possible wood damage would be another concern.
This is cracking paint on a bathroom ceiling. Although code allows for a window to be considered venting you can see that the moisture collecting on the ceiling has caused the paint to begin peeling in large sections. This is about 12" across. What you see in the middle is exposed plasterboard which now is absorbing moisture and drying into the attic space.
With this job I performed 4 years ago.
I built the kitchen renovation for the customer.
The issue I have is the previous window contractor and siding installer NEVER told the customer there was a moisture and rot problem in the wall.
I had to replace the sill plate and supporting stud from the inside.
I used construction glue on the exterior sheathing and wrapped the sill from the inside under the new window.
Luckily the sheathing was still in good shape.
I also spray the wood to get rid of the mold and dry out overnight prior to re-insulating and boarding.
