Pool Liner Replacement & Renovation — St. Catharines, ON
A worn liner doesn't have to mean a worn-out pool.
Rivermark Pools inspects, measures and replaces vinyl pool liners for homeowners across St. Catharines and the Niagara region. Every project starts with a written estimate, not a guess — and finishes with a walkthrough of the first-fill chemistry so the water is ready to swim in.
What we do
Three stages cover most liner projects: the inspection and estimate visit, the standard replacement, and — where a pool also needs coping or step-edge work — the premium renovation package.
Liner Inspection & Estimate Visit
A measured inspection of the existing liner's seams, wrinkles and fade, followed by a written estimate comparing a standard and a textured liner option for the pool's shape.
$140 CAD
Standard Vinyl Liner Replacement
Removal of the worn liner, wall and floor preparation, and fitting of a new vinyl liner sized to the pool, finished with a refill and a walkthrough of the first-fill chemistry steps.
$700 CAD
Premium Textured Liner Renovation Package
A full renovation pairing a heavier textured liner with coping and step-edge touch-ups, scheduled as one combined project to refresh the pool's overall appearance.
$1,340 CAD
A local liner crew, not a call centre
Rivermark Pools is a small, St. Catharines-based team that focuses specifically on vinyl liner work — inspection, replacement and the renovation details that go with it, such as coping touch-ups and step-edge repair. We measure every pool ourselves before quoting, because liner fit is the single biggest factor in how long a replacement lasts.
We're operated by Niagara Pool Liners LTD., a registered Ontario business, and we work mostly by referral across the Niagara region.
Learn more about us →Who this fits
Homeowners with a fading liner
Visible wrinkles, chalky fade or a seam starting to lift are the usual signs it's time for an inspection visit.
Pools due for their first replacement
Most vinyl liners run 10–15 years before they need replacing; we'll tell you honestly where yours stands.
Owners planning a wider refresh
If coping and step edges look tired alongside the liner, the renovation package bundles the work into one visit.
Anyone unsure what they need
The inspection visit alone gives you a written comparison of options, with the decision to go further left entirely to you.
How the work goes
First contact
You call, email or send the contact form; we ask a few questions about the pool and liner age.
Inspection & estimate
We measure the pool on site and leave you with a written estimate comparing liner options.
Scheduled installation
Once you approve the estimate, we book a date and prepare the walls and floor before fitting the new liner.
Refill & follow-up
We refill the pool, walk you through first-fill chemistry, and check back once it's settled in.

Common questions
How long does a standard liner replacement take?
Most standard replacements are completed within a single scheduled visit, from draining through refill, though the pool needs a few days afterward to reach swimming temperature.
Do I need the inspection visit before booking a replacement?
We recommend it. The inspection gives you a written comparison of a standard and a textured liner for your pool's exact shape, so the replacement estimate is based on real measurements, not a guess.
What's included in the renovation package?
The premium package pairs a heavier textured liner with coping and step-edge touch-ups, scheduled as one combined project rather than separate visits.
