"One oven doesn't work at all ( my choice, see above), the "working" oven was never calibrated properly so using it is hit or miss. It's time to call American Home Shield to see about replacing the entire unit. I'm waiting to finish other home projects before calling them. I don't know if I'll request Greenway again."

Install Above Ground Pools FAQs, answered by experts

It is generally not recommended to place a pool directly on grass. Doing so will kill the grass underneath, and the surrounding lawn may also be damaged by heavy foot traffic and splashes of chemically-treated water. For best results, create a clean, level surface by removing the grass and debris. You can then install a sturdier base using materials like sand, a concrete pad, or solid foam.

Endless pool may refer to one of two things. For some, it’s a term used interchangeably with infinity pool. Because infinity pools don’t have a visible edge, they look endless. For others, it’s a brand of jetted lap pool. Endless pools are engineered to fit in small spaces, but provide the benefits of a full-sized pool (think: aquatic exercise or hydrotherapy). You can even use them indoors, and they’re relatively budget-friendly because of their small size.

An in-ground concrete pool will carry the highest price tag of all available types of pools, with architectural or freeform concrete pools found at the top end of the price range. Although the upfront costs for a concrete pool are high, these pools tend to be more durable than pools made from other materials and will last the longest. 

Yes, salt water pools are more expensive than chlorine-based pools because they require a more complex system than traditional, chlorinated pools. This added complexity means more skilled labor and a higher investment upfront. Also, if you need to repair a salt water pool, finding a contractor with the needed experience is generally more time-consuming.

The total time to install an inground pool typically ranges from 8 weeks to 4 months. This timeline can be influenced by several factors, including permitting, site preparation, and the construction process itself.

Key phases and their typical durations include:

  • Permits: Obtaining necessary permits can take anywhere from two to six weeks.

  • Excavation and Site Preparation: This phase takes about a week but can be extended by problematic soil, unexpected ground conditions, or the need to move underground utility lines.

  • Construction: The actual build, including plumbing and electrical work, often takes one to two months. The pool material is a major factor here; a concrete pool needs about 30 days to cure, while installing a fiberglass or vinyl liner is much faster.

External factors can also cause significant delays:

  • Contractor Availability: Spring and summer are busy seasons, and high demand can lead to long waitlists, potentially adding months to your start date. It is often recommended to start planning and getting estimates up to a year in advance.

  • Other Delays: Weather, material shortages, complex designs, and other unforeseen challenges can extend the project timeline.
