A clearly displayed house number increases the chance that the pizza delivery driver makes it to you door with a warm pizza, friends and family find your home easily, and packages and post make it in a timely fashion. Mounting options depend on your home's construction and siding. For wood posts and siding as well as stucco and brick, mount the numbers directly on the post or home. If you have vinyl siding and don't want to install the numbers on wood or masonry accents, use vinyl siding hooks for plaques or construction adhesive for single numbers.
Screw and Bolt Mounted Numbers
Hold the template for the first number against the installation location. Place a spirit level directly underneath and adjust the template until it's angled as desired. Tape it in place. Repeat this with each subsequent number.
Outfit a drill with a bit intended for your siding, sized to work with the bolts or screws supplied with the house numbers. For stucco, brick or stone siding, use a masonry bit. A basic twist bit works well for wood siding, columns and doors.
Drill through the screw hole marks on the template, going through the paper and into the surface underneath. Some housing numbers recommend starting with a smaller bit, drilling all of the pilot holes, and then drilling again with a slightly larger bit. Typically, this is only necessary for flush-mounted numbers. For the best results, always follow the directions that came with your kit.
Attach the bolts to the backs of the numbers if applicable. If desired, add spacers to the base of each bolt after attaching them to the numbers to create a floating effect.
Apply a dab of silicone caulk to the end of each bolt on the first number and into the pilot holes in the home or post. Push the number into place. Wipe away any excess caulk, and tape it up with painter's tape. Repeat this with each subsequent number.
Remove the tape once the caulk is dry, about 12 hours.
Mounting Numbers to Vinyl Siding
Push the clip end of a low-profile stainless steel vinyl siding hook with a screw between two slats of siding at a slight upward angle. Move the hook downward until it clicks, locking it in place. Repeat this process with each additional hook. Some hooks may install in a slightly different manner; always follow manufacturer directions.
Hold the plaque to the siding and adjust the hooks so that the screw holes line up with the holes on the plaque. Screw the plaque in place, going through the face of the plaque and into the screw holes on the hooks. Twist a nut onto the end of each screw or bolt.
Attach single numbers to siding with construction adhesive. Draw a level or angled line at the installation point with a level and chalk pen. Hold the numbers against the line, and mark off the right and left side of the bottom edge of each number to create a guideline.
Apply the adhesive to the back of the first number and press it against the siding, lining it up with the guidelines. Temporarily secure it in place with painter's tape. Wipe away any excess adhesive. Repeat this process with each number. Remove the painter's tape once the adhesive is dry.
