A beautifully crafted address stone is a lasting investment in curb appeal. Whether you’ve chosen a stone address block, stone house numbers, or a freestanding natural stone address marker, proper care ensures it continues to look pristine for years. Here’s your go-to guide for routine maintenance, seasonal checks, and simple repairs to keep your custom stone address plaques and stone mailbox numbers in top condition.
Frequency: Every 6–12 months
Tools & Materials: Soft-bristle brush, mild soap (pH-neutral), water, garden hose
Remove loose debris. Gently brush away leaves, dust, and cobwebs from the stone surface.
Mix cleaning solution. In a bucket, combine warm water with a few drops of mild, pH-neutral soap.
Scrub gently. Use the soft-bristle brush to clean the engraved numbers and edges of the address stones. Avoid wire brushes or harsh chemicals that can damage sealants or paint.
Rinse thoroughly. Spray with a garden hose on a low-pressure setting until all soap residue is gone.
Air dry. Let the stone air dry completely before any sealant application.
Frequency: Annually, preferably in spring
What to Look For:
Hairline cracks or chips along edges
Faded or peeling paint in engraved numbers
Loose mortar joints for built-in stone address blocks
Action Steps:
Small chips: Fill with a color-matched masonry patch.
Cracks: For cracks under 1/16″ wide, apply a clear masonry crack filler.
Paint touch-up: Refill engraving with high-contrast, monument-grade paint.
Frequency: Every 2–3 years (or as needed in harsh climates)
Products: Breathable masonry sealer, exterior-grade paint for engraving
Choose a compatible sealer. Pick a breathable, water-repellent sealer labeled safe for limestone or concrete. We recommend Prosoco Siloxane WB Concentrate.
Apply sealant. With a clean brush, coat horizontal surfaces and edges—avoid clogging engraved numbers.
Let cure. Follow manufacturer’s instructions (usually 24–48 hours).
Refresh paint. Once sealed, refill your stone house numbers or stone mailbox numbers with black monument paint for maximum visibility.
Frequency: Pre-winter inspection
Tips:
Ensure sealant is intact to repel water.
Clear snow promptly—use plastic shovels to avoid scratching the stone.
Avoid rock salt directly on or around the stone; opt for sand or kitty litter for traction.
For built-in address stones set in brick or stone walls:
Check mortar joints. Look for crumbling or gaps around the edges.
Repoint as necessary. Remove loose mortar and apply fresh mortar to maintain structural integrity and prevent water infiltration.
Harsh chemicals: Bleach, acid cleaners, and pressure washers can erode sealants and paint.
Abrasive tools: Metal scrapers or wire brushes will scratch the stone face.
Neglect: Skipping routine checks allows minor issues to become major repairs.
A little maintenance goes a long way. By following these simple steps—regular cleaning, annual inspections, timely resealing, and mindful winter care—you’ll preserve the beauty and functionality of your address stones for decades. Remember, properly maintained stone address plaques not only look fantastic but also enhance your home’s value and curb appeal.
