Tile-Ceramic-Contractors & Dealers Our house numbers are terra cotta or white clay tiles formed and glazed by hand. These decorative house numbers are done in bas-relief (low-relief) to enhance their visibility and lasting beauty. Our tile house numbers and signs are fired to a temperature that will assure the natural beauty of their colors and durability over time. They are engineer-tested for freeze-thaw resilience to endure cold climates. The rich, unique colors and textures of our tile house numbers create a small work of art for your home. Designs derive from architectural styles and ornamentation. We also use imagery from nature as decorative motifs.
