Land Surveying questions, answered by experts

Land surveys don’t technically expire. They do serve as a point of reference and a snapshot of your property, though, so as soon as you make changes to your property (and even if your neighbor makes certain changes to theirs), your existing land survey becomes inaccurate, and a new one must be done. Even if you don’t make any changes to your property, many states only guarantee the accuracy of a land survey for five to ten years.

When considering the price of drilling a well, factor in how much you’ll save in water costs per year. The average family of four uses 100 gallons of water per person per day in the U.S. With a private water well, you can save hundreds each year.

Wells are also environmentally friendly. You don’t need to worry about drinking water treated with chemicals. Talk to at least three well pump contractors in your area. They’ll be able to tell you more about your options, give you different quotes, and discuss the biggest concerns.

Surveys completed by licensed surveyors can be recorded with a local surveying records office, and in most cases, they will be. Filing survey reports categorize them as legal documents, and they can be used whenever legal documentation of your property’s boundaries is needed. While you’re not required to file survey documents, it’s a good idea to do so. 

Land surveying can help give clear guidance on your property boundaries for numerous situations. And in some cases, having your land surveyed is a requirement. Some common reasons to have your land surveyed include:

  • Planning for construction projects, like building a fence

  • Locating utilities, such as plumbing fixtures

  • Settling property line disputes 

  • Creating subdivisions 

  • Meeting mortgage requirements

  • Selling your property

To hire a land surveyor, you need to start by searching online for reputable professionals in your area. Here are a few steps to take when making a shortlist:

  • Browse land surveyor service website

  • Check credentials

  • Read customer reviews

  • Find their contact information

  • Call or email to inquire about more information

  • Ask how far they travel, if you’re some distance away

  • Find out how they charge for their services

  • Ask about schedule and turnaround times

  • Repeat these steps for one to two other services and compare pricing
