It typically takes around 30 to 60 minutes for a window pro to replace one window in standard siding types, but a window in stucco will likely take a bit longer because of the density of materials. Custom architectural windows usually require a longer replacement process because of the additional fitting and securing required.

Repaired stucco requires regular inspections, cleaning to prevent mold or mildew build-up, and timely minor repairs to address hairline cracks. Applying protective sealants can also enhance longevity and maintain its appearance.

Failing to repair damaged stucco can lead to significant problems. Cracks can grow and deepen, allowing water and moisture to get behind the stucco. This moisture intrusion can cause water damage, structural issues, and mold or mildew growth. Delaying repairs will likely cost more in the long run as the damage worsens, so it's best to repair your stucco as soon as you notice any signs of damage, such as cracks, holes, or discoloration.

A standard drill will work just fine if you’re drilling small holes, and only a few of them. But anything with a diameter larger than 3/8 inch is best done with a hammer drill, since it is stronger, faster, and also makes your drill bits last longer. While you don’t absolutely need a hammer drill for stucco, it is a worthy investment if you think you might drill more holes down the road.
