Where not to drill in a wall? - Fix It Cape Town

Drilling into walls may seem like a simple task, but without proper knowledge and precautions, it can lead to disastrous outcomes. Whether you are hanging a picture frame, installing a shelf, or mounting a TV, it is essential to be aware of what lies behind the walls to avoid damaging electrical wiring, pipes, or structural elements. In this article, we will take you through a step-by-step guide on how to safely drill into walls, along with some frequently asked questions and useful tips to ensure a successful outcome.

Step 1: Locate Studs and Electrical Wiring

Before grabbing your power drill, it is crucial to identify the location of studs within the wall. Studs provide the necessary support for heavy objects, such as shelves or cabinets. Using a stud finder, slowly run the device across the wall until it detects a stud. Mark the spot with a pencil or masking tape.

Next, you should check for any electrical wiring in the area where you plan to drill. An electrical stud finder can help you locate live wires behind the walls. Running into hidden electrical wiring while drilling can pose a serious safety hazard. If you are unsure, it is best to consult a professional electrician.

Step 2: Choose the Right Drill Bit and Drill

Selecting the appropriate drill bit and drill is crucial to ensure a smooth drilling process. The type of wall material you’re working with will determine the choice of drill bit. For common wall materials such as drywall or plaster, a general-purpose drill bit should suffice. However, for tougher materials like concrete or brick, a masonry drill bit is required.

When choosing a drill, consider the size and weight of the tool. A cordless drill with adjustable speed settings is recommended for versatility and maneuverability. Make sure the drill is securely tightened before use and that you have a fully charged battery or a nearby power source.

Step 3: Use Proper Safety Gear

Safety should always be a priority. Before you start drilling, make sure to wear protective eyewear to shield your eyes from any flying debris. Additionally, using ear protection is advisable, especially if you anticipate a loud drilling noise. Lastly, keep a dust mask on hand to protect yourself from inhaling any dust or airborne particles generated during the drilling process.

Step 4: Mark the Spot

Using a pencil or masking tape, mark the exact point where you want to drill. Double-check the location to ensure it aligns with your desired outcome, such as hanging a frame at eye level or positioning a shelf evenly.

Step 5: Start Drilling

Before drilling into the wall, it is wise to start with a small pilot hole. This allows you to check for any unexpected obstacles and verify that you are on track. Gently squeeze the trigger, applying a steady, even pressure to the drill. Avoid forcing the drill or angling it, as it may lead to a crooked or uneven hole.

Step 6: Secure the Screw

Once the pilot hole is complete, you can proceed to drill the actual hole required for your project. Insert the appropriate screw or wall anchor into the hole, ensuring it fits securely. Use a screwdriver or suitable tool to fasten the screw, making sure not to overtighten and risk damaging the wall material.


Q: What should I do if I accidentally hit a pipe or electrical wire while drilling?
A: If you accidentally hit a pipe or electrical wire while drilling, immediately stop drilling, turn off the power supply, and contact a professional plumber or electrician for assistance. Do not attempt to Repair or replace the damaged element yourself.

Q: How can I avoid damaging the wall surface while drilling?
A: To prevent damage to the wall surface, choose the appropriate drill bit size for the screw or anchor you are using. Start with a pilot hole and apply gentle pressure throughout the drilling process. If necessary, use a piece of masking tape over the drill area to provide extra protection from scratches.

Q: Can I drill into any part of the wall without worrying about hitting anything?
A: No, it is crucial to exercise caution and follow the steps outlined in this guide. Walls may contain essential elements such as electrical wiring, plumbing, or structural supports, which can cause serious damage if accidentally penetrated. Always use a stud finder and be aware of potential obstacles before drilling.


Drilling into walls doesn’t have to be a daunting task, as long as you take the necessary precautions and follow the correct procedures. By locating studs, identifying electrical wiring, using the right drill bit and drill, wearing safety gear, and marking your drilling spot, you can ensure a successful and safe drilling experience. Remember to exercise caution, double-check for potential obstacles, and seek professional help if you encounter any unexpected issues. With these guidelines in mind, you can confidently tackle your next DIY project, knowing that your walls and surroundings are protected.
