Soil testers and licensed excavators are often the professionals you hire if you need a perc test. In some cases, structural engineers will also be able to conduct the test for you. In many municipalities, you’ll need your professional on-site to dig and fill the holes with water, as well as a representative from your local building department or health department. That representative is the individual who will determine whether your test passes or fails.

Professionals prevent misalignment, ensure sturdy construction, and save time by handling complex instructions.

A few different types of land surveys can help determine certain features and boundaries of your property. These include:

• Boundary surveys describe the actual borders of a property. These are generally required when trying to get construction permits issued. 

• Location surveys provide much of the same information as a boundary survey but also include in-depth information about any improvements made to your property. 

• Mortgage location surveys are usually required by lenders and title companies before financing or offering an insurance policy. 

• Site-planning surveys are done before applying for building permits and can be issued before any major home improvements. 

• Topographic surveys provide a formal map of land elevations. It can also describe the location and size of natural features and any land improvements.

If you or your mortgage lender think your land survey needs to be more accurate, double-check the survey report and get at least a second opinion from the original surveyor and an inspector, if possible. Although it’s unlikely, even reputable surveying companies can make mistakes. An inaccurate survey can cause problems down the road in the case of any property line disputes, so it’s best to resolve any inaccuracies as quickly as possible.
