If there is one part of a house to wire while it is still open, it is the outside walls. Interior walls can sometimes be reached later with patience. Exterior walls are a different story.
Why exterior walls are so difficult
Exterior walls are built to keep weather out and hold the house up, and that makes them crowded inside.
Insulation fills the cavities, making it hard to feed a wire through after the fact.
Bracing and structural framing add blocking that a wire can't easily pass.
Two-story construction means a wire may need to travel from an attic or equipment room down past a floor system to reach the right spot on the first floor.
Once the drywall and exterior finishes are on, getting a wire to the right place can mean cutting into walls, patching, and repainting, or settling for a spot that isn't quite right.
What usually goes on exterior walls
Many of the features families care about most are on the outside of the house:
Security cameras covering entries, driveways, and the backyard.
Outdoor speakers for the patio, pool, and outdoor kitchen.
Patio TVs for game days and evenings outside.
In the Houston climate, outdoor living is a big part of how many families use their homes for much of the year. A covered patio with good sound and a well-placed TV becomes another living room. Cameras around the perimeter provide everyday peace of mind.
Pre-wire now, decide later
The simple solution is to pre-wire during construction. That means running the wire to every spot where a camera, speaker, or TV might go, even if some of those spots won't be used right away. Wire run during framing is inexpensive and invisible. Wire added later is neither.
It also gives families flexibility. Maybe the outdoor TV waits until the patio furniture is chosen. Maybe a camera is added after the landscaping fills in. With the wire already in the wall, each of those decisions is easy.
Walk the exterior before it closes up
Before insulation goes in, it is worth walking the outside of the house with your integrator and thinking through how each area will be used. That walk takes an afternoon and saves years of compromises.
