Yes, adding a pool to your property will almost always increase your homeowners insurance premiums. This is because pools are considered hazardous, which increases your home's liability risk. The replacement cost of the pool itself is also factored into your home's rebuilding cost when determining coverage limits. The amount of the increase can vary from as little as $50 to several hundred dollars more per year, depending on your insurance company, location, current coverage, and installed safety features. It is best to contact your insurance agent before installing a pool to get an estimate, understand their specific guidelines, and factor the ongoing cost into your budget.

Both above ground and inground pools can have pool liners. Inground pools made of gunite don’t need pool liners, and you’ve probably walked along an unlined pool and felt the ripples and ridges on the floors and walls. But adding a liner over gunite or other pool types helps protect the wall panels from algae growth.

The best temperature to paint a pool deck is between 50 and 90 degrees Fahrenheit, because many paints and sealers require temperatures warm enough for the chemical reaction to take place for proper curing. The paint should not be allowed to freeze, and temperatures above 90 degrees can cause the paint to dry too quickly, also preventing the chemical reaction from following through to completion.

It's not a good idea to drain an aboveground pool into your yard since the pool water's chemicals can harm your plants and the surrounding ecosystem. Instead, it's best to drain the pool into an appropriate sewer so it can be processed at a water treatment plant. You might also be able to drain it into your storm drain, depending on your region. Check with your city to learn about any relevant regulations.
