Who does a perc test?

• <div><p>Soil testers and licensed excavators are often the <a href="https://www.angi.com/articles/who-does-perc-tests.htm">professionals you hire if you need a perc test</a>. 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. </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>

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: What should I do before hiring an excavation company?

• <div><p>Prior to excavation, you should prepare the dig site and call 311 before you sign anything.</p><p>To get your site ready for excavation, you should move anything in the area that isn&rsquo;t affixed to the land. You can save money on the excavation by removing hardscaping, including walkways, decks, concrete patios, and paver patios.</p><p>Before you carry out any digging, you should call 311 to confirm that there are no utility lines running through your excavation site. Skipping this step could lead to severe injury and property damage if your excavator hits a water, sewage, or gas line.</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>

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...

The survey was done weeks behind schedule. I had to keep calling to see when they do the survey. I never saw the stakes in the ground.

"I hired Standard Land Surveying Co. to determine our property line because my new neighbors were installing a fence between our houses and I wanted to be sure they were installing it on their property. I contacted them and spoke to Carlos who explained what they will do to determine our property line and after they were finished they explained the findings and showed me the markers that shows my property line. I was very happy with Standard Land Surveying Co. and I am glad I chose them for this project."
