    Frequently Asked Questions

    Please reach us at hello@360poolcare.ca if you cannot find an answer to your question.

    Liners are custom-made, taking about 2–3 weeks to manufacture.


    Once delivered, installation is completed in one day, and the pool begins filling the same day.


    Yes — every project includes a free onsite measurement so the liner is made to the exact size of your pool.


    We install 30 mil vinyl (also referred to as 35 gauge) for long-lasting durability.


    Yes — all skimmer and return gaskets are replaced.


    Main drains have two gaskets:

    • One under the liner (stays in place)
    • One on top of the liner, under the faceplate (this one is replaced)

    The liner is vacuum-set, and once water rises, the main drain is cut in, the top gasket replaced, and the faceplate installed and sealed watertight.


    Minor floor repairs and patching are completed before installation to ensure a smooth finish.


    No — water is not included.

    Homeowners can fill the pool themselves or arrange water delivery.


    Yes — every installation includes a 1-year workmanship warranty handled directly by 360 Pool Care.


    The liner itself also carries a manufacturer warranty.


    No — all installations are completed by 360 Pool Care, never subcontractors.
