Concrete Pools

Concrete pool with slide


  • Can be built in any shape or size, with any combination of features
  • Many options for the interior finish


  • Due to the cement-based finish, concrete pools will require the most money and effort to keep clean
  • Concrete pools will get rough and stained over time
  • Concrete pools will require the interior plaster (marcite) to be replaced, and possibly new waterline tile
  • Concrete pools are only as good as the crews that build them
  • If (or when) there is a problem with the concrete shell, repairs are very expensive

Vinyl Liner Pools



  • Due to their vinyl interior finish, this type of pools require less money and effort to keep clean than cement finish pools
  • Replacing the liner is a relatively simple process, essentially giving you a new pool


  • When the liner fails, the pool no longer holds water
  • Extra care must be taken to protect the pool liner
  • The vinyl liner will need to be replaced every 8-10 years

Fiberglass Pools

  • Quick installation 
  • Backed and warrantied by national manufacturers
  • No expected renovations needed
  • Same waterline tile and decking options as concrete pools


  • Must choose from the sizes, shapes, and colors available

Why Fiberglass?

  At Paragon Pools, we believe that inground fiberglass swimming pools are the best type of pool for most residential backyards here in North Florida.

The interior gelcoat finish of the fiberglass pool is non-porous, and does not react with the water.  The algae, bacteria, and other contaminants do not stick to the surface of the pool.  This results in significantly less money having to be spent on chemicals to keep the water clear.  This also keeps dirt and debris from adhering to the surface of the pool.  Which means less time and effort being spent to keep the pool clean!

The sides of the fiberglass pool are very smooth.  No more snagged bathing suits or skinned elbows from rubbing up against the sides of the pool!  The steps and floor of the pool have a texture that is built in from the factory.  This texture keeps you from slipping as you get into and out of the pool.  Don't worry, the texture is not rough!  Sore or skinned feet are not an issue with the gelcoat finish.

Fiberglass pool shells are stronger than concrete pool shells.  In fact, many swimming pool experts claim fiberglass pool shells are 10-15 times stronger than concrete pool shells!

The interior finish of today’s fiberglass pools will never break down.  It will never wear, or have areas that break down. 

Fiberglass pools will never require a renovation due to the pool shell or the pool interior finish breaking down, wearing out, or otherwise falling apart!

Fiberglass pools are built and backed by national manufacturers.  The pools are built in climate-controlled manufacturing facilities by trained technicians.  This provides quality control every step of the way.  It also allows the manufacturer to provide a true lifetime warranty to back your pool.

Because your pool is delivered to your jobsite complete, we are able to install fiberglass pools much faster than any other type of inground swimming pool!  Depending on the complexity of the project, we can typically complete the construction process in 4 weeks or less.  Often as little as 2-3 weeks from the time we break ground until you can swim in your completed pool!  How quickly do you want to swim?

Are All Pool Contractors Equal?

Installing an inground swimming pool is a major construction process.  And each and every jobsite has its unique challanges to overcome.  It is your contractors responsibility to be sure that the process goes smoothly.  After all, this is why you hire a contractor in the first place!

What kind of access does your jobsite have to get materials and equipment into and out of your jobsite?  Will fencing, landscaping, or driveways be damaged during the process?  Is there anything buried in the ground?  Pipes, wires, septic or drainage systems often leave no evidence on the surface when they are buried.  

Will fill dirt be need to be brought in to bring your project up to grade?  Will any excavated soil need to be hauled off?  What about the existing soil conditions?  Will the excavated soil be suitable to use in filling and grading around your new pool?  Will ground water be present when the pool hole is dug?  Your contractor should have the expertise to handle all of these ground conditions.  Will there be an extra charge for any of these conditions?  In order to avoid misunderstandings after the job has started, it is imperative that these items are addressed prior to the beginning of construction!

Will your contractor use in-house employees or subcontract out the construction?  Your contractor is directly responsible for in-house employees.  They have passed the application process, and have their personal information on file in the office.  Your contractor is responsible for their actions and schedule while the employees are in your backyard.  Contractors have very little control over subcontractors.  Subcontactors are responsible for their own schedules; for the employees they choose to bring into your yard; and for the quality of work they leave behind.  Most subcontract experiences are positive!  Most subcontractors are highly skilled in their area of expertise, and are brought in to perform a specific phase of the job.  The most important thing is knowing who will take responsibility for anything that happens in your backyard!

Will my pool "pop" out of the ground?

Will my pool pop out of the ground?

Is a fiberglass pool more likely to pop out of the ground than a concrete pool?

The simple answer to these questions is: If you do not drain your pool, then your pool will not pop out of the ground!

In North Florida, it is not uncommon to have a high water table.  What we mean by that, is if you dig a hole in your yard, it is not uncommon to have water accumulate in that hole.  When we dig the hole in your backyard for your new pool, it is not uncommon for us to have to control the ground water during construction.  This ground water must be controlled until the pool is filled with water.  Once the new pool is filled with water, the weight of the water will hold the pool down, and prevent the pool from ever popping up out of the ground.

If the pool is ever drained, the pool becomes a boat.  And, the pool-boat will float.  It does not matter what the pool shell is made out of.  A fiberglass boat will float.  So will a concrete boat.  And, so will a great, big, metal ocean liner.  It is a simple law of hydraulics.

The pool in this picture was a concrete pool that became a concrete pool-boat.
