Think about the homes you have listed, sold or lived in. Visualize the entrance. How wide are the steps? Are they so narrow that only one person can walk up? Is there a railing? How sturdy is it? Are the rails just vinyl or are they metal reinforced? Can you move large pieces of furniture up those steps? Is it wide enough? Is the landing or porch solid (compacted dirt, rebar, block, and moisture barrier) or does it just have a sheet of metal and dirt and then filled with concrete? If brick is used, are the steps edged in a hard angle or are they edged in bullnosed brick. The costs of the special building materials may be only a little more than average but the costs of the professional who has the experience to do the installation correctly drives up the costs of the house.
