The most common survey, a title survey land surveying companies perform is a map locating all buildings, fences and other structures on the property as well as improvements on adjacent properties. This type of land survey is particularly important in real estate purchases so you can identify any issues that could adversely affect your boundary lines. At Gluckler & Den Bleyker, land surveying is what we do; it is not an add on service. In New Jersey, a title survey, by law, includes the setting of property corner markers.
