Smaller pools cost less, are easier to maintain, require smaller less expensive pool covers, smaller less expensive decks, are cheaper to heat, take up less of your yard, and installation cost is less.

Value Proposition

Here is the great thing about the Liberty Pool Line… It does not cost as much as the big “Brand Names,” but you get all the technology, and the exact same color azure finishes as other Latham pools. They are all made in the same factory!

Liberty Composite Pools are built by the same manufacturer as Viking Pools and Trilogy Pools. All three of these brands are manufactured in the same Latham Pool factory. Great pools, different names!

Additional Costs

Regular Seasonal Maintenance

To not void your warranty, a lot of pool companies require you to hire them for yearly opening, and closing services. Then they charge you twice the going rate or more. We do not require you to hire us for warranty purposes, but if you do want our seasonal services, we charge only $225~ for an opening or closing.

Winter Elephant Cover | Safety Cover

You will need a winter pool cover too. We do not charge retail for winter safety covers when you buy a pool from us. We charge just 10% over cost. Cover installation is an extra $150~ to $450.~

Pool Patio Fees

If you do a 3/4 promenade Patio and finish one straight side with grass or landscaping, you are usually left with 700 square feet. 10’x30′ side patio with two four end patio sections. This configuration gives you plenty of area for lounging and the ability to walk to either end of the pool.

  • Broom Finish Concrete $9.00 –  9×700=$6300.00
  • Exposed Aggregate Poured Concrete $12.00  – 12×700=$8400.00
