Liberty fiberglass pool warranty explained

Both phrases appear, and it is worth knowing which one counts. Liberty's home page describes a limited lifetime warranty, and a note on its warranty page says Latham offers a lifetime warranty on its fiberglass pools. The same warranty page, and the written warranty itself, give the actual terms: the shell is warranted to be structurally sound for 25 years, and the finish is guaranteed against osmotic blistering for 20 years, with restrictions.

The written document is titled Limited Lifetime Warranty, and the coverage inside it is 25 years for the structure and 20 years for the surface. We quote the written terms, because that is what a claim is judged against. Liberty's warranty page also points out that its warranty has changed over the years and that your coverage is the warranty you were given with your pool, not the most recent version. So the document delivered with your pool is the one that governs.

Everything below is from the 2025 version, published on Liberty's site. It is a plain-English summary, not legal advice.

The warrantor is the manufacturer. The document names Liberty Pool as a branded product line of Latham Pool Products, Inc. It covers the original purchaser at retail and residential use only. It states that using the property as a hotel or a temporary or short-term residence counts as commercial use and voids the warranty, which matters if you plan to rent the house out by the night. Pools sold as blemished or as-is are not covered.

Because the 2025 document extends only to the original purchaser, do not assume it will pass to the next owner if you sell. If transfer matters to you, ask about it before you buy and read the version you receive.

• Structure, 25 years. Leaking due to structural failure caused by faulty workmanship or materials in making the shell. Structural failure means water loss from a fracture, void, crack or similar separation that came from a manufacturing defect. The document states plainly that it warrants the pool to hold water.
• Surface, 20 years. Osmotic blistering of the gelcoat finish due to defects in materials or workmanship. Osmotic blisters are small bubbles that form when water works into the laminate behind the gelcoat.
• Tile, 3 years. Tile affixed by Latham, from the date Latham ships the pool, against damage to the tile line from original transport and against faulty tile application.

If a covered structural failure happens, Latham chooses whether to refund the price it received for the shell, repair it or replace it. The same choice applies to covered blistering.

Coverage depends on several conditions being met at all times. The ones that matter most day to day:

• The pool stays full of water. The document says so twice, in capital letters, and failing to keep the water above the skimmer outlet voids the warranty entirely.
• The pool is installed by an authorized dealer, or by a licensed contractor or owner who follows state and local codes, the ANSI/APSP-5 standard for residential inground pools, the owner's manual and Latham's installation procedures.
• The water chemistry is kept to the owner's manual. The warranty lists general targets of 1 to 3 ppm chlorine, pH 7.2 to 7.6, total alkalinity 80 to 120, calcium hardness 250 to 350 and cyanuric acid 40 to 60. It says the water should be tested weekly by your pool professional and that you should keep the printouts, because Latham can ask for them in a claim.
• The pool is used and maintained as the owner's manual describes, and Latham gets access to inspect it.

The exclusions list is long. The ones owners run into most often are these:

• Fading, staining, discoloration or other changes in the gelcoat's look or texture, other than osmotic blisters.
• Damage from draining the pool improperly, or from the groundwater table rising above the pool's water level.
• Damage from runoff, or from failing to drain rainwater away from the pool and deck.
• Settling soil, shifting earth, flooding and other acts of nature.
• Decks, concrete, waterfalls, spas and other attached structures, plus fittings, skimmers, piping, lights and wiring.
• The beam, meaning the top edge of the shell under the coping. Latham expects it to be covered by a cantilever deck, pavers or other coping, and crazing, chips or color variation there are not grounds for a claim.
• Costs of removing the pool or installing a replacement, lost water and chemicals, and loss of use.

The document also says Latham does not warrant the installation, which is done by independent dealers, and that a claim found to be caused by improper installation or maintenance can be rejected.

Because our ground is often wet. The USDA describes Mahoning silt loam, one of the most widespread soils on this region's till plains, as holding a perched water table 6 to 12 inches below the surface from October through June in most years. The Liberty warranty is voided by allowing groundwater to build up under or around the pool, and it excludes damage from the water table rising above the pool water or from runoff not drained away.

In practice, that makes three things part of protecting the warranty here. The pool needs a way to relieve groundwater, such as a sump line at the deep end. The finished grade and the deck have to carry rain away from the pool, not toward it. And the pool stays full, winter included. A fiberglass pool here is closed for the season with water in it, lines blown out and equipment winterized. Draining it in wet ground is exactly the situation the warranty excludes, and never worth the risk.

Act quickly. The warranty requires written notice within 10 days of discovering a condition you believe is covered, and within 5 days for damage from transporting the pool. Notice goes by email to FGPwarranty@lathampool.com and must include:

• your name, address, phone number and email
• the pool's serial number, which is on the second step
• the installation date and the name of the dealer who installed it
• a detailed description and photos of the problem

Missing the notice or leaving out that information can waive Latham's obligation. Write the serial number down now, on the form at the end of the warranty, while the pool is new. Liberty's website also has an online claim form and a page to register your pool.

If a repair is approved, the document puts draining and bracing the pool, and removing groundwater from around it, on the owner, and it notes that repaired areas may show slight color or shade differences. Disputes go to individual arbitration through the American Arbitration Association, held in Bridgeport, West Virginia, rather than to court.

A few minutes of paperwork in the first month makes any future claim far easier:

• Keep the warranty document that came with your pool, not a printout of whatever version is online later.
• Fill in the owner form at the back with the serial number from the second step and the installation date.
• Register the pool through Liberty's website, and register the Pentair equipment with Pentair.
• Take dated photos of the finished pool, especially the steps, benches and waterline, so you have a record of how the gelcoat looked on day one.
• Start a folder for water test printouts from your pool professional. The warranty says Latham can ask for them.
• File your builder contract, permits and final inspection in the same place.

None of that costs anything, and it answers most of the questions a warranty department will ask.

Not the Liberty warranty. The shell warranty covers the shell. The installation is covered by whatever your builder puts in your contract, and the Ohio Attorney General advises that a home improvement contract include a clear statement of any contractor guarantee or warranty. Ask every builder you talk to what workmanship coverage they offer, in writing.

The equipment carries its own manufacturer's warranty. Pentair, whose pump, filter and lights come in our packages, ties the length of its coverage to product type, where it was bought and proof of professional installation, and it asks owners to register their products to activate coverage. Register everything in the first weeks, and keep the invoices with the pool warranty.
