Unfortunately once a pool is in, the costs do not end. If you want to avoid algae, get a filter. You will also want ladders, long handled skimmers and perhaps a heating unit for the chillier days. And this heater plus the filter are often housed in a permanent structure for protection and aesthetics. There are solar heating devices that can cut these heating costs as well, and your contractor should be able to give you some viable choices. As the solar units are costly, the heating savings may not be seen for a few seasons.
Add diving boards, slides and even hand rails to the must-have list. Count on a pool cover to keep debris and varmints out and to keep in some of the heat generated by your heating unit.
Inground pools also cry out for surrounding landscaping for privacy and wind screening and any pool fixed addition, such as lighting, is going to be cheaper in the long run to put in congruently with the pool itself. As you plan your pool venture try and site the pool in a sunny section of your yard to keep heating costs down, and utilize the house for screening and privacy purposes. Also keep in mind that trees in your yard may constantly shed into the pool, plus root systems can be destroyed during the excavation.
Many states and municipalities require fencing around the pool so wandering neighborhood children cannot accidentally fall in and drown. These fencing ordinances can be quite specific including height and material directives. Look at any and all your local building codes before you finalize your pool plans. They may significantly impact your financial budget and construction time frame.
