Overlap, beaded and unibead liners are not interchangeable. Each attaches to the pool differently, fits a different wall type and carries a different price. The useful question is not which one is best, but which one your pool was built to take.
Look at where the liner meets the top of the wall. An overlap liner wraps over the wall and is trimmed or hidden by coping. A beaded liner has a thick edge that snaps into a receiver track. A unibead liner hangs on the wall. If you are not sure, take a photo of the top edge before you ask for quotes, because the answer changes the price and the installation method.
Overlap is the least expensive route, at $150 to $600 for material, and it lasts about 5 to 9 years. It is common on above-ground pools. Overlap is also the most forgiving during installation, because the installer can stretch and adjust the liner before trimming the excess, which helps on a pool whose walls are not perfectly straight.
Beaded liners cost $500 to $1,000 for material and last 10 to 15 years. They are required for most inground pools, because the bead holds the liner in a track at the top of the wall instead of relying on stretch and trim. A beaded liner is not a drop-in choice for a pool built for an overlap liner, and an overlap liner is not a drop-in choice for a beaded pool.
Unibead liners, also called J-hook, run $200 to $900 for material. They are built to hang on the wall or fit into a bead receiver, which makes them a common option when the original hardware is hard to source or when a homeowner wants flexibility on the next change.
Because they work with more than one attachment style, ask the installer to confirm your specific wall and track before you order, rather than assuming the name means it will fit anything.
If your pool has a track but the old liner was an overlap, or a previous owner changed the wall profile, the installer needs to measure the actual receiver before ordering. Getting that wrong means the liner arrives and does not fit, and a rush replacement order adds $200 to $500 on top of the original job.
| Type | Material Cost | Typical Life | Best Fit |
|---|---|---|---|
| Overlap | $150 - $600 | 5 - 9 years | Above-ground pools |
| Beaded | $500 - $1,000 | 10 - 15 years | Most inground pools |
| Unibead / J-hook | $200 - $900 | Varies by product | Pools needing flexible attachment |
Changing liner type is not only a purchase decision. Moving from an overlap liner to a beaded one usually means adding a bead receiver track, which is extra work on top of the liner itself.
Material is only part of the bill. Labour runs $250 to $800 above ground and $1,000 to $2,500 inground, while skimmer and return repairs add $100 to $400 and old liner disposal adds $75 to $200. If the existing track turns out to be damaged, that becomes another line item, so ask how it will be priced before work begins.
When a liner has pulled loose from its track, the cause is not always the liner. Wake County soil is clay-heavy and drains slowly, and expansive clay movement works on pool walls, floors and coping, so a track that has let go can be a sign of movement behind the wall. Ask the installer to look at the wall condition before ordering a replacement, because a new liner will fit the same way if the wall is out of true.
There is no universal best. Overlap is the cheapest and suits above-ground pools, beaded is required for most inground pools and lasts 10 to 15 years, and unibead or J-hook offers flexible attachment. The right choice is the one your pool was built to take.
Look at the top of the wall. An overlap liner wraps over the wall and is trimmed or covered by coping. A beaded liner has a thick edge snapped into a receiver track. Take a photo of that edge before requesting quotes.
Often, yes, but not for free. Moving to beaded usually means adding a bead receiver track, which is extra work on top of the liner. Ask the installer what hardware must be added and how it will be priced.
Material alone runs $150 to $600 for overlap, $500 to $1,000 for beaded, and $200 to $900 for unibead or J-hook. Installation is separate, at $250 to $800 above ground and $1,000 to $2,500 inground.
Overlap liners typically last 5 to 9 years. Beaded liners typically last 10 to 15 years. Unibead and J-hook liners vary by product, so ask the supplier for the expected life of the specific liner you are quoted.
A vinyl liner is the waterproof skin of the pool, and Raleigh pools replace one every 5 to 15 years.
Almost every inground pool without a concrete or fibreglass finish is a vinyl-liner pool, and the liner is a consumable.
An inground liner is fabricated to your pool, not pulled off a shelf, so measurement quality decides the result.
Above-ground liners are the cheapest job in this niche and the one homeowners most often try themselves.
Not every liner problem needs a new liner, but the ones that cannot be repaired are usually the ones that get patched too long.
A new liner over a failing shell is money spent twice.
