Behind the Walls: Why Pre-Drywall Checks Are Crucial for Your New Home

Hi everyone, Eric Christie here from Boxer Inspections! Today, I want to take you behind the scenes of a recent inspection to show you exactly what we look out for before the walls of a new house are closed up. I was recently out on a job site over in the Independence Heights area, walking through a newly constructed two-story home. This particular visit was for a pre-drywall inspection, which some people in the home building industry also commonly refer to as a framing inspection. This stage of the building process is absolutely crucial because it is our last chance to seethe "bones" of the house. Before the drywall goes up and hides everything from view, a thorough home inspection is necessary to catch potential hidden dangers.
As a dedicated home inspector, my job involves going room to room and carefully checking the structural and installed systems of the house. One important item I want to share with you guys today—and something I specifically look for during every single framing walk-through—has to do with the proper protection of the electrical wiring.
Let me paint a picture of what I saw at this two-story Independence Heights property. In the back of one of the rooms, you could clearly see some ROMEX wiring running straight through the wooden wall studs. Now, running wire through studs is a standard way to wire a house, but there are requirements in the building standards about how this wiring must be protected from damage. When I got closer to inspect a specific section and focus my camera on it, I noticed a potential safety issue.
I focused my attention on one particular wire and realized it was sitting a little bit less than an inch away from the outside edge of the wooden stud. Why does this measurement matter so much? Well, building standards require wire protection if the wiring sits too close to the surface. The exact distance we are checking for is anything less than 1¼ inches from the edge of the stud. If a wire is closer than that 1¼ inch mark, builders are required to install a special protected metal plate on the stud.
At this house, because the wire was a little less than an inch from the edge, they definitely needed to install one of those protected plates. But why is this specific requirement so important for you, the future homeowner? Think about what happens when you finally move into your brand-new home.You are going to want to decorate! You will likely be putting a screw or a nail into the walls to hang up your favorite family photos, large mirrors, or heavy artwork. If that electrical wire isn't protected, and it is sitting too close to the surface of the stud, your nail or screw could easily pierce right through the wire.
That simple metal plate acts as a crucial barrier. It is there specifically to protect the wire so that when homeowners are hammering in a nail or driving in a screw, they are not going to pierce the electrical wiring hidden behind the drywall.
When I am walking through a property, going from room to room, looking for these vulnerable wires is a huge part of what I do. After a while, you really start to get an eye for it. You can glance at a wall and almost immediately see which wires are sitting too close to the edge and are not going to meet the safety requirement. When I spot these issues, my process is simple but thorough: I take my measurements, I take a picture for the documentation, and I officially note it as a deficiency in the report.
Catching these missing protected plates early is exactly why checking the home at the framing stage is so incredibly important. Once the drywall goes up, you can no longer see exactly where those wires are hiding. If you are building a new house, you definitely want to make sure your construction home is inspected at the pre-drywall phase.

3 Tips for Homeowners Wanting to Hang Objects on Walls
Based on the hidden hazards we look for behind the walls, here are three tips to keep in mind before you start decorating.
Remember what hides behind the drywall: Always keep in mind that essential utilities, like ROMEX electrical wiring, run directly through the wooden studs inside your walls.
Watch your nail and screw depth: Because safety standards only mandate protective plates for wires sitting less than 1 1/4 inches from the edge of the stud, be cautious if you are driving screws or nails deeper than that into your walls.
Listen to the wall's resistance: Builders install metal protected plates over studs specifically to shield shallow electrical wires from getting pierced by a screw or nail. If you are hammering or drilling into a stud and suddenly hit a hard metal barrier, stop immediately—that plate is doing its job to protect a wire!
