"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

Consultation with the local government helps identify necessary permits, avoid project delays or legal issues, and protect project integrity.

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.

This is fairly rare, but sometimes the local government or a group like a historical society will label a tree as a landmark, or historical item. These designations almost always come with a small, on-site plaque for identification, but you should also be able to look up protected trees in your area on a city website or similar list. If the tree in question is a landmark, call your local government and ask how to proceed before making any plans.

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 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.
