Q: Who do I call before I dig in my yard?

• <div><p>If you&rsquo;re planning to dig on your property, you&rsquo;ll need to check for underground utility lines. Call the national call-before-you-dig 811 number. Once connected to an operator, you can schedule a site visit to mark underground lines. This way, you won&rsquo;t accidentally dig into pipes and can cause major (read: costly) issues. </p></div>

Q: Is it worth it getting a land survey?

• <div><p>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.</p></div>

Q: How much does it cost to prepare land for a mobile home?

• <div><p>Costs vary, but you can expect to spend between $1,000 and $4,000 to prepare land for a mobile home or before you <a href="https://www.angi.com/articles/how-much-does-it-cost-build-house.htm">build a house</a>. You&rsquo;ll need to clear enough land for the foundation, which may require leveling or grading, as well as removing trees, stumps, and plants. Don&rsquo;t forget to plan for permits and fees and the installation of a gas line, water line, and sewer main.</p></div>

Q: How do well drillers know where to drill?

• <div><p>Professional well contractors may use electromagnetic mapping to look for places with a high likelihood of water. Water access can vary significantly, even on the same property, so it can be difficult to know where to drill if you don&rsquo;t have specialized tools to look for water.</p></div>

Q: How long is a land survey good for?

• <div><p>Land surveys don&rsquo;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&rsquo;t make any changes to your property, many states only guarantee the accuracy of a land survey for five to ten years.</p></div>

At the estimate, Tony arrived on time, surveyed the property, made good recommendations for the number and location of cameras and gave us an estimate. We already had an excellent recommendation for his services and had one other estimate, which was twice the cost, so we went with Tony. Tony...
