Mounting house numbers or house markers onto stucco can be a challenge. Some stucco surfaces can be very uneven, wavy, or brittle.

Most individual house numbers or house number plaques come with matching screws only. We recommend purchasing standard plastic anchor inserts matched to the screw size.

The house number screws will then screw securely into the plastic anchors.
Before drilling anything, measure twice and use a level (we cannot stress this enough). Use a masonry drill bit for drilling your holes (make sure the drill bit is properly sized to the anchors). Use a smaller sized drill bit first and then widen with a drill bit sized appropriate for the plastic anchors.

You can squirt some silicone adhesive or exterior grade silicone caulk into the holes to hold the anchors in more securely if you like before pounding into the hole(s).

Now...here is the challenge....
The stucco or stone surface is uneven.
So what you can do is use some very small washers (around the screws and behind the numbers or plaque) to raise the numbers or plaque off from the stucco surface. You can play around with this using more washers on some screws than others in order to get an even look. Try and use brass washers if possible. Or you can order 1/4" spacers from us (please inquire).



The result will be sort of a "floating" look as if it were mounted with stand offs.
But this is a far better look than a haphazard uneven appearance.

Floating house numbers have screw in pins on the back and you can control how far off of the surface the number will be. As an example, click on this link.

We also offer Craftsman style house number backer boards for mounting individual house numbers.

We also offer address wall plaques which are easier to install than individual house numbers because with a plaque, there are typically only 2 screw holes.
