The questions below are the ones that decide whether a liner job goes well. Where a published figure exists it is quoted; where the answer depends on your pool, the answer is what to ask and what to check.
Frequently asked questions
How much does pool liner replacement cost in Charlotte?
Published 2026 figures: $2,100 to $3,000 for a standard 16 x 32 inground pool, $3,000 to $5,500 for a 20 x 40, and $6,500 to $9,000 and up for large or custom pools with steps and ledges. Above-ground pools run $700 to $2,500 for the full job. Add refill water ($60 to $350 on city supply) and any repairs found after drain-down.
How often does a vinyl liner need replacing?
Vinyl liners are generally replaced every 5 to 15 years. Overlap liners typically last 5 to 9 years, beaded liners 10 to 15. Sun exposure, chemistry and the quality of the original fit all move that range.
Do I need a permit for a liner replacement in Charlotte?
A liner-for-liner swap normally needs no permit in North Carolina. Replacing wall panels, changing the shell, adding or altering an underwater light, or doing equipotential bonding work requires a Mecklenburg County permit and inspection.
How long will my pool be out of service?
Ordering takes 2 to 5 days for measurement and 5 to 15 days for fabrication or shipping. The on-site work is usually a few days: drain-down and removal, repairs, installation, then refill and balancing.
Can I keep the water and just replace the liner?
No. The liner is fitted to the shell and trimmed around the fittings, so the pool must be drained and refilled.
Who supplies the refill water?
It depends where you are. Charlotte Water serves Charlotte, Gastonia and Matthews; Town of Huntersville Utilities serves Huntersville and Cornelius; Concord has its own water resources department; Mooresville runs its own water system. City supply costs $60 to $350, trucked water $400 to $900.
What is the difference between 20, 27 and 30 mil liners?
Mil is a thousandth of an inch. Moving up a step adds $200 to $700. Many builders prefer 20 mil for stretch and fit, and a well-installed 20-mil liner outlasts a badly installed 30-mil one.
Overlap, beaded or unibead?
Overlap liners ($150 to $600 material, 5 to 9 years) drape over the wall and suit most above-ground pools. Beaded liners ($500 to $1,000, 10 to 15 years) snap into a track and are required for most inground pools. Unibead or J-hook liners ($200 to $900) can work either way.
What does the liner warranty actually cover?
Manufacturer warranties are pro-rated limited warranties, for example 20 years on a 20-mil premium liner or 25 years on an AquaMax-class liner. They do not transfer to a new owner and exclude labour, water, chemicals, fading and chemistry damage. Installation is covered separately by the installer's workmanship warranty, typically 1 to 3 years.
Is a liner warranty affected by a DIY install?
It can be. Some liner warranties require professional installation, so check the terms before starting. Above-ground DIY saves $250 to $800 in labour, but wrinkles or a poor waterline seal shorten the liner's life.
What repairs might come up once the pool is drained?
Rusted or pitted wall panels, a soft vermiculite floor, failed bead receivers, and worn skimmer, return and light gaskets. Published bands: wall and spot repairs $150 to $600, floor patching $150 to $3,000, gaskets $100 to $400, floor rebuild $1,200 to $3,000.
Why do Charlotte pools need more wall and floor repair?
Mecklenburg County soil is clay-heavy, drains slowly and moves with moisture, and Mooresville and the rest of the Piedmont share that profile. Water held against the shell corrodes steel panels, groundwater can float a liner, and movement opens voids in the floor base.
When is the best time to replace a liner?
Late autumn through winter for spring installation is the cheapest window, saving $500 to $700 on a typical $3,500 job. Peak season is spring and early summer, with longer waits. Vinyl is also easier to work with in warm weather, so schedule the install day accordingly.
Should I replace the liner before selling the house?
A torn or leaking liner is a defect a buyer's inspection will flag, and a pool that will not hold water is a liability rather than an amenity. The liner is not mainly an appraisal line; it is damage control.
Can the liner colour be changed?
Yes, at replacement. Check your homeowners association's approved colours first, because re-ordering a fabricated liner in a different colour wastes the original order.
Does a new liner stop the pool from leaking?
Only if the leak was in the liner. Gaskets, the skimmer throat, the light niche and plumbing all leak independently, and a failed gasket is a $100 to $400 fix. Diagnose before assuming replacement.
