Today's Chicago Tribune ran an article on concrete driveways. With Spring approaching (or already present in most parts of the U.S.), many homeowners will be looking for contractors to do various jobs around their homes like driveways, grilling patios and walkways. A littleÂ research and smart marketing can helpÂ concrete contractorsÂ grab some extra dollars on these types of projects. Got a homeowner who wants an estimate on replacing a concrete driveway? Give them a three-tier estimate -- the plain concrete,Â colored concrete with a stamped border, and a fullyÂ stamped drive and stainedÂ concrete. You'll be givingÂ homeowners optionsÂ they might not know about or know they wanted. A homeowner might not be able to afford a fully stamped and stainedÂ driveway, but a stampedÂ pattern at the end of the driveway or a stamped border around the edge willÂ give themÂ some decorative flairÂ and you some extra dollars.
