Ideally, you choose a surveyor who is professional in their approaches. They should be businesslike and should promptly return calls, answer emails, and must also explain to their customers how surveys are conducted. Remember to ask the professional or a written contract. The written agreement should stipulate the services that will be rendered and all payment terms. The typical practice is for the professional to get part of the total fee when they sign the contract and sending the bill balance once the work is done satisfactorily. A surveyor must mark property corners using permanent markers that will stay indelible through the years. The primary purpose of employing professional land surveyors is determining the outline or extent of the property. The right permanent markers to use nowadays include magnetic nails, railroad spikes, plastic stakes, iron pipes, and iron rods.
