Pool Liner Faq in Raleigh, NC

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.

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.

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 City of Raleigh permit and inspection.

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.

No. The liner is fitted to the shell and trimmed around the fittings, so the pool must be drained and refilled.

It depends where you are. Raleigh Water serves Raleigh, Wake Forest and Garner; Town of Cary Utilities serves Cary and Morrisville; Apex has its own water resources department; Durham runs its own water system. City supply costs $60 to $350, trucked water $400 to $900.

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 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.

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.

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.

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.

Wake County soil is clay-heavy, drains slowly and moves with moisture, and Durham 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.

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.

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.

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.

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.

Installations are checked against a 50-item QA protocol across six phases: pre-job planning and material verification (8 items), site and substrate preparation (9), measurements and custom CAD fitting (7), placement, seams and vacuum set (9), hardware, gaskets and water refill (8), and post-fill chemistry and maintenance (9). Every phase carries a 100% pass target, and each phase has a named sign-off role — lead tech, site inspector, CAD specialist, lead tech, plumbing tech and service manager.

The published field standards: ambient air at least 60 F (16 C) for thin vinyl, with a 55 F minimum; zero active rust on steel wall panels; 10.5 oz geotextile felt underlayment (plus or minus 0.5 oz); no more than 1% variance on CAD-measured perimeter and hopper specs; hot-air weld seams a minimum 3/4 inch wide and continuous, with no THF or solvents; 100% seam probe testing with zero pinholes or cold welds; stainless flange bolts no more than 3 inches on center (3.5 inches maximum); and vacuum positioning that pulls the vinyl taut with zero wall air gaps.

The six critical-risk items in the protocol are unreinforced vinyl unfolding in cold temperatures, unisolated concrete expansion joints, over-stretching vinyl beyond 20%, false hot-air welds or seam pinholes, cutting vinyl before flange compression, and dry chlorine shock dumped onto the pool floor.
