Whenever i do attic wiring i remove the insulation and staple it to the ceiling joist.
Running wires through attic with no access.
And if you have big baseboards you could create the wall damage behind the baseboard run the wire along the bottom of the wall and then when you place the baseboards back they would cover the drywall damage.
Raul no this is not a standard practice and is most likely the result of improper installation of electrical attic wiring.
Where are the best locations to cut the sheetrock to allow for access.
If this meets code then i will be running attic wiring in this manner from now on.
With a flashlight examine the attic and locate the path that you will use to run the wire between the two locations.
Climb through the attic access using a ladder if necessary and look into the attic space.
I think some folks are thinking you mean knob and tube wiring since you said exposed.
Running wires without attic or basement.
Yes this should be corrected and it would be good to have the wiring and all the circuit connections inspected as well.
Without attic access i am lost.
If the attic is your only access space for running cable you may find it necessary to cut another small hole in the wall surface high on the wall in order to gain access for drilling through the wall s top plate.
Cut out your circle of drywall which will leave you with access to either side of the joist stud.
You should drill through the middle of the stud not notch it.
I have done this same project with attic access.
This hole can be patched once the wiring work is completed.
The attic wiring should be protected and secured to ceiling joists or other wood structural supports.
If there is no access to an unfinished space to run the wires in such as with a first floor ceiling or perpendicularly across a stud wall i use a 4 or 5 inch hole saw centered on each joist stud.
Watch the entire process step by step.
But we need to know the type of wire and the type of access to the attic scuttle hole stairs to provide a complete answer.
I was also under the impression that if wiring is in an attic space that it may need to be derated because it can get very hot up there.
