"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."

"Excellent! Kirk, the General Manager was also the sales person. He was helpful, honest, forthright, personable, prompt, dependable, and reachable. His crew were professional and hard working. Their craftsmanship was excellent. They got my house and garage roof done in one day! As well as installed the gutter guards. They were near the cheapest bid but were not the cheapest but, I hired him/them because he had all the positive qualities listed above. I would recommend them, as well as hire them again!"

Install Above Ground Pools FAQs, answered by experts

Yes, you can put too much shock in a pool, and it is crucial to follow the directions on the product you are using. Adding excess shock can upset the chemical balance, make the water cloudy, have adverse effects on swimmers, damage pool equipment or surfaces, and even encourage certain types of algae to grow. If you have over-shocked your pool, perform a water test and adjust the chemicals as necessary. The pool's chemical balance will eventually return to normal as the excess chlorine dissipates over time.

It’s okay to leave a pool pump on 24-7. In fact, running it continuously has big upsides, including consistently distributing chemicals, keeping a steady pool temperature, preventing algae growth, and keeping pool water clean. However, there is a tradeoff—operating a pool pump around the clock increases energy costs and can take a toll on the pump’s longevity. If you want to run your pool pump all the time, invest in energy-saving equipment like a variable-speed pump.

While you shouldn’t notice water that has an appropriate amount of chlorine in it (less than 4 parts per million), you could feel sick from drinking overly chlorinated water. Chlorine exposure can cause nausea, vomiting, coughing, and dizziness. Chronic chlorine exposure (meaning multiple or repeated instances) can make you feel like you have the flu, according to the CDC.

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.

The most expensive part of building a pool is typically the excavation and labor, which can account for 25% to 50% of the total project cost. This is particularly true for inground pools that require significant excavation, potentially including the rental of large equipment, and extensive construction labor. In contrast, above-ground pools are generally less expensive as they typically do not require excavation and can be installed much more quickly. Concrete in-ground pools are among the most labor-intensive options.
