"Josh is very responsive and helpful. He helped us solve a problem and have advice for the future but also did not try to up sell us and let us know what was not needed. He replaced our pool pump and gave us options and pros & cons for each. We had a leak a week later and he came right out and fixed it (a pipe just needed to be tightened). I feel comfortable going to him with future concerns."

"Chris and his crew (Dillon, Chase and Austin) did an amazing job of transforming our back yard from blah to wow. Chris was very creative in designing everything from the raised berms, dry creek bed to the siloam steps from our patio to the yard. We would hire Chris again and would quickly recommend him to any of our neighbors looking to doing some landscaping in their yards."

Pool Construction and Installation FAQs, answered by experts

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.

Land surveys are worth it in several scenarios including selling your home, building an addition, constructing a fence, or making major changes to your landscape. A professional land survey can help you avoid legal issues with your neighbors and confirm the value of your property. In many cases, you may be required to order a land survey to receive a construction permit or mortgage loan.

Construction typically takes 3-6 months, including site preparation and assembly.

Property lines, building locations, and potential encroachments are mapped.
