How to Insert Screws Without Damaging Stucco

At Golden Trowel, we understand your challenges when adding fixtures or modifying your stucco walls. Stucco, a popular exterior finish in Calgary, requires careful handling to maintain its beauty and integrity. Whether you’re:

  • Hanging decorations
  • Installing lights
  • or attaching other items to your home’s exterior

It’s crucial to do it right. 

Here’s our expert guide on how to insert screws into stucco in Calgary without causing any damage.

1. Choose the Right Tools and Materials

Before you start, selecting the right screws and anchors is vital. Use screws that are specifically designed for your stucco in Calgary. These typically have wider threads that securely grip the building material without causing cracks. You will also need a masonry drill bit for pre-drilling holes. This type of bit is made to bore into hard, brittle surfaces without cracking them.

2. Pre-Drill the Hole

Mark the spot where you want to insert the screw. Using a power drill with your masonry bit, carefully drill a hole slightly deeper than the length of the screw. This step is crucial as it prevents the stucco from crumbling or cracking when you insert the screw. Ensure the hole is the correct size for the anchor — not too loose or tight.

3. Insert the Anchor

A suitable anchor is recommended for added support and to distribute the weight more evenly across the stucco, especially for heavier items. Tap the anchor gently into the pre-drilled hole with a hammer. Be careful not to apply too much force, which could damage the stucco. The anchor should fit snugly within the hole without any gaps.

4. Screw in Carefully

Once your anchor is set, it’s time to insert the screw. Align your screw within the anchor and slowly tighten it using a screwdriver or a drill on a low torque setting. Avoid overtightening, which can cause the anchor to expand excessively and damage the stucco.

5. Seal the Deal

After the screw is in place, consider applying a small bead of silicone caulk around the edge of the hole. This step seals the hole, preventing water from entering and potentially damaging the stucco in Calgary’s variable weather. This sealing helps maintain the durability and aesthetic of your stucco exterior.
