Just finished Attic, Insulation, Ventilation, and Interior course. Sharing picture of the vents from an exhaust ventilation system.
That’s a great inspection image. And a good catch. Here’s an article about bath fan exhaust that you may want to use for writing narratives related to this condition: http://www.nachi.org/bathroom-exhaust.htm
Hi guys, just sharing this picture of an attic space from an old house I inspected. Absolutely no insulation in these old houses. The roof was in the process of being replaced at the time which is why you can see light coming through.
Hello, I am submitting an image demonstrating moisture issues as required for course completion.
this is an image in a bathroom where obvious moisture damage is taking place. The damage in the sheetrock is most likely due to a leak in the drain or supply lines. However, it also could be due to condesation as there is no outside ventilation other than the window. The homeowner should be informed of the damage and possibe mold issues.
Here is a photo to satisfy the requirement in course “Attic, Insulation, Ventilation and Interior”. This is a photo of the attic in a Florida home built in 1963 with solid wood sheathing. It is Truss roof framing and toe-nailed roof to wall connections. There is no insulation in this part of the attic which can cause higher energy usage. It was recommended that owner have proper insulation installed.
Not the best representation image for the course, however I am overseas and my options are limited. Overview shot of the interior of a living room. Picture does not show very well the water stains at the top of fireplace drywall.
Per the online course requirements I submit the following:
The inspection of the attic area revealed bathroom vents terminating into the attic space. I wrote this up as follows…
The exhaust fans do not vent to the exterior at the upstairs bathrooms. Vent pipes that terminate in attic space can sometimes cause moisture that can lead to mold or cause condensation. A qualified person should repair as needed.
This photo shows a powered vent in an attic installed poorly. The fan is try to exhaust air horizontally through a gable vent, but it was mounted approximately 10 inches from opening with no shrouding at all.
Location: Area behind commode in 1st floor bathroom.
Open interior wall area without means of closure. This open area may facilitate the movement of air and thus water vapor within the framework to other areas of the structure as well as the possible entry of insects.
No damp areas were observed at time of inspection.
post from Attic and Interior
Here is a picture of a noticeable air leak at the front door. The weather strip is cut short of the head rail on the door frame allowing an air gap. Suggestion: Replace weather stripping on door of adequate size and length.
Here is an example of water intrusion into my home from the shower pan. Apparently the pan has failed therefore water has created dry rot and mold in portions of the walls along the bottom plate. Landlord has not agreed to a corrective measure as it would entail likely removal of all drywall on effected walls and replacement of studs.
Picture share requirement:
The bathroom fan appears to have been installed non-professionally. There are 2 voids on both sides of the fan unit which could contribute to air leakage. I recommend repair or replacement by a qualified contractor.
Who knew there was so much to know about insulation? Not me.
Homeowner replaced the traditional wooden railing with a nice metal one. Not your typical railing but still had to measure each gap to pass the Sphere test.
As required for the class here is my picture. It is of an unfinished basement looking up at the floor joist. It is properly insulated since there is only living space above none below. Also note the r rating on the products Kraft backing.
Hey Everyone,
So I was in the bathroom at my moms house and I looked up to see this a/c vent. I figured that there wasn’t much ventilation back there. It’s an interior bathroom with no window. It has an exhaust fan which after further investigation I found that it exhausts directly into the attic. It doesn’t even have flex attached to it. With more ventilation, perhaps a vent/can light protected by a GFCI and terminating above the roof, the moisture would not build up and the vent would not have rusted. What do you think?
