A pool is a treasured, long-term commitment. 

As you dream of your backyard pool and you shop around, either online or by visiting a pool dealer, you’ll likely have a lot of questions.

Fiberglass pools are made to last. Just think, your kids and grandkids could enjoy the same pool! Additionally, fiberglass is an algae-resistant material.

Depending on pool size, the cost can range from $10,000 to $15,000, and you’ll be able to fill the pool and jump in almost immediately. A less expensive option is epoxy paints.

Do you repair, replace, renovate or remove? These are questions you may have to consider as you weigh the benefits of resurfacing an older pool.
