I had a question and wanted to know if this would be a problem with cold air entering my home. I did a renovation last year and the electrician cut the drywall to add wiring for undermount lighting in the kitchen. The only thing he didn't do was tape the vapor barrier back together where he cut (exterior wall). I tested that area with a thermal gun and it gave a reading of about 3-4 degrees colder than the other walls. Do you see this as being a problem? Thank you.
The vapour barrier should have been sealed as it is there for a specific purpose. You can probably live with the temperature difference, but moisture may become an issue over time. I would suggest having the repair done to ease your concerns.
Hi Mark, Thanks for your reply. I will continue to look into this matter further. If it comes down to it I will have to take apart my kitchen to seal it back up.
