How much does it cost to drain, clean, and reset a floating liner in an Ottawa inground pool?

Draining and resetting a floating liner in an Ottawa inground pool typically costs $800 to $1,500 when performed by a professional pool service company. This price includes draining the pool, cleaning the liner and pool shell, identifying and addressing the cause of the floating, and refilling with proper water chemistry adjustment.

However, draining a vinyl-lined pool in Ottawa requires extreme caution due to our climate conditions. Completely draining a vinyl liner pool can cause the liner to shrink permanently, especially during cooler months when vinyl becomes less flexible. More critically, Ottawa's high water table in many areas means that groundwater pressure can actually push the entire pool shell up out of the ground when the weight of the water is removed - a catastrophic failure that can cost $15,000 to $30,000 to repair. This hydrostatic pressure problem is particularly common in areas like Barrhaven, Orleans, and parts of Kanata where the water table sits relatively high.

The safer approach is partial draining to just below the floating section, which reduces the risk while still allowing access to reset the liner. Professional pool technicians will assess the specific cause of the floating - whether it's groundwater pressure pushing up from below, improper initial installation, or damage to the liner's attachment system. They'll also check for tears or weak spots that might have contributed to the problem.

Critical timing consideration: Never attempt this work during Ottawa's freeze-thaw season (November through April). The combination of cold temperatures making vinyl brittle and potential groundwater issues makes this strictly a warm-weather repair. Most pool professionals won't perform full liner resets between October and May for safety reasons.

If you're dealing with a floating liner, it's worth having an experienced pool contractor assess whether a full drain is actually necessary, as many floating issues can be resolved with partial draining and proper re-stretching techniques.
