Phoenix, AZ homes often feature beautiful stucco exteriors that protect against the intense desert sun and add timeless charm. But when you need to mount a heavy item—like a security camera, shade sail, or even holiday décor—you need to find the wall studs underneath without damaging the stucco.
Finding studs behind stucco isn’t as simple as it is with drywall. It takes the right tools and careful technique. Here’s how homeowners in Phoenix can safely and accurately locate studs behind stucco.
Key Takeaways
Studs are usually located 16 to 24 inches apart behind stucco
Use specialized deep-sensing stud finders or magnetic stud finders
Drilling small test holes can help verify stud locations
Protect your stucco by using proper anchoring methods
Why It’s Challenging with Stucco
Unlike drywall, stucco is thick, textured, and layered over plywood or lath, making it harder for standard electronic stud finders to detect changes in density. In Phoenix, many homes also have foam insulation layers, adding another obstacle.
Using the right tools and techniques ensures you avoid unnecessary damage and keep your exterior walls strong.
Best Tools for Finding Studs Behind Stucco
For Phoenix homeowners, the following tools work best:
Deep Sensing Stud Finder: Look for models like the Franklin Sensors ProSensor series that can detect through thick surfaces
Magnetic Stud Finder: Finds the nails or screws in the underlying lath or sheathing attached to studs
Drill with Masonry Bit: For careful test drilling if needed
Measuring Tape and Chalk: For mapping once you find one stud
Bonus Tip: Always test your stud finder indoors first to understand how it signals a stud.
Step-by-Step: How to Find Wall Studs Behind Stucco
Start from Windows or Doors
Studs are usually installed along the sides of doors and windows. Start scanning near these areas.
Use a Deep-Sensing Stud Finder
Move slowly across the wall surface, marking when your stud finder indicates a solid area.
Switch to a Magnetic Stud Finder if Needed
Slowly move it across the surface. You’ll feel it “grab” onto nails or screws under the stucco when you’re near a stud.
Drill a Small Pilot Hole
Once you’ve marked a likely stud location, drill a tiny hole with a masonry bit. If you hit solid wood after about an inch, you’ve found the stud.
Confirm Stud Spacing
Measure 16 or 24 inches from your first mark to find the next stud, confirming you’re following the framing structure.
Tips for Phoenix Homeowners
Perform the work early in the morning when the stucco surface is cooler and less brittle
Seal any unnecessary holes immediately with stucco patch material
For heavy installations, use specialty stucco anchors designed to spread the load across a larger area
