“Easily the best experience we’ve ever had with contractors of any type, across both residential and commercial experiences. Keystone was incredibly professional, they kept us updated on progress with permits and approvals without us having to check in, they were proactive, and once they got started building, they incredibly finished on schedule.”

Swimming Pool Contractor FAQ's

An average size for a home swimming pool is 16x35 or 560-600 square feet. Depth varies from pool to pool and depends primarily on the owner's preference. 

Yes, a swimming pool can easily be incorporated into a deck or patio. If you'd like help with envisioning this or brainstorming, our design team is happy to help! 

Swimming pools can last quite a long time if you take care of them. In fact, both fiberglass and concrete pools have a lifetime warranty on the pool shell, and most have a 15-20 year warranty on the finish. 

The time it takes to install a pool can vary depending the complexity of the project. However, most fiberglass pools take 3-4 weeks to install while concrete pools take 2-3 months to install. 

There are a number of materials available for constructing a swimming pool, but fiberglass and concrete are usually considered the two best options. 

Anyone that ones a swimming pool and has young children should be careful to protect their children. You also need to know that there is a risk assumed with having a swimming pool. 

However, there are several things you can do to make a swimming pool more safe for children: 

1. Put a fence around your swimming pool

2. Add a safety cover if possible

3. Alarms that sound when a person or animal enters the pool.

4. Self-locking gates

5. Gradual slope from the shallow to deep end of the pool. 

Pools are fun no matter what shape they are in. And sometimes, people prefer specific shapes for certain reasons. 

However, rectangular pools are usually considered the most versatile and are the easiest to add pool accessories like water nets.
