Whether you are part of a commercial real estate firm, residential real estate agent or a for sale by owner, Landmark Sign Company is here to help. We produce all types of real estate signs, including yard signs, riders, site signs and banners. Traditionally real estate site signs have been made of MDO, which is a type of plywood, however these type of signs tend to trap moisture and begin to warp and bow. Our signs are produced from either Alumalite or DiBond. These products are a strong, aluminum composite panel with a high density, corrugated polyallomer (CPA) core. Unlike wooden signs Alumalite and DiBond will not swell, corrode, rot, or delaminate even under prolonged water exposure.
