Fountains questions, answered by experts

While there’s always a possibility that pests will appear in and around a natural swimming pool—much like regular swimming pools—they largely deter pests due to their natural filtration system, which keeps things clean and the water constantly moving.

In short, yes, a pond can add to your home’s value. However, whether it adds value will depend on the condition and aesthetic of your pond. Having this feature already built into a yard’s home can be appealing to homebuyers who value its aesthetic and would prefer not to build it themselves. But if it is not kept in good condition, it could turn buyers away.

Lifespans vary by material and manufacturer, but pond liners last anywhere from 10 to 75 years. For example, polyvinyl chloride (PVC) pond liners have a life expectancy of up to 20 years. Other types of pond liners, including those made of high-density polyethylene (HDPE) and ethylene propylene diene monomer (EPDM), can last 40 to 50 years.

Installing an outdoor water fountain costs $2,700 on average, not including the cost of the unit. Prices range from $150 to $10,650, depending on your location, the type of fountain, size, and accessibility to the site. Self-contained fountains and water features recirculate the water within the unit. Depending on size and features like multi-tiered cascading bowls, they typically cost from $50 to $5,000. More elaborate fountains with waterfalls and ponds can cost from $450 to $10,000 or more.

Fountain maintenance is an important part of having a clean foundation in the first place. To keep your fountain water clean, you can use a water additive designed specifically to limit scale, algae, and other buildup in fountains. Or opt to use white vinegar as a pantry-ready water additive.
