The two appointments that matter are the opening and the closing, and of those the closing is the one that can cost you real money if it goes wrong. Everything else — the weekly visits, the chemistry, the vacuuming — is a question of how you want to spend your summer. This page covers what each costs and the timing that matters in this climate.

Closing: the narrow window
Close too early and you seal warm water under a cover for weeks, which is how a pool comes up green in May. Close too late and you risk a hard freeze reaching water still sitting in the plumbing, skimmer or heater — and a cracked heater or a split return line is the failure that turns a $600 closing into a $4,000 spring. The working window in this area is roughly mid-to-late September through mid-October, once the water is consistently below about 15°C but before a sustained freeze. Good crews are routed by August, so book early. If you close it yourself, the parts that matter are blowing the lines properly and plugging them, and getting the water level right relative to the skimmer.
Opening, and what a green pool costs
An opening runs $400 to $700 and is worth booking earlier than feels necessary — a pool opened in early May and balanced is far less work than the same pool opened in June after the water has warmed under the cover. If it does come up green, a green-to-clean recovery is $400 to $1,200 depending on how far gone it is, and most of that is chemicals and repeat visits rather than labour. On a well, ask what the opening includes if the pool needs a significant top-up; a slow-recovering well changes the job and sometimes needs a water delivery.
Weekly service, and doing it yourself
A weekly visit runs $90 to $180 and a full-season package $1,800 to $3,800. What you are buying is chemistry that stays in range without you thinking about it, which matters more on a heated pool and one under trees. Doing it yourself is entirely reasonable — the equipment is not complicated — but the two things that catch people are testing frequently enough in hot weather, and running the pump long enough. Most problems people call about are one of those two rather than anything mechanical.
Common questions
How much does it cost to open and close a pool in the Ottawa area?
In 2026, a standard inground pool opening runs $400 to $700 and a closing $400 to $750. A full-season weekly maintenance package is $1,800 to $3,800, or $90 to $180 per individual visit.
When should I close my pool in Manotick?
Roughly mid-to-late September through mid-October — once the water is consistently below about 15°C but before any sustained freeze. Closing too early traps warm water under the cover and produces a green pool in spring; closing too late risks water freezing in the plumbing or heater, which is a far more expensive problem.
My pool is green — what does it cost to fix?
A green-to-clean recovery typically runs $400 to $1,200, driven mostly by chemicals and repeat visits rather than labour. It is usually the consequence of a late opening or a pool closed too early the previous autumn.
Can I fill or top up my pool from a well?
Topping up is usually fine; a full fill often is not, since it takes tens of thousands of litres and will run a modest well hard. Many properties here use a water delivery for the initial fill and after a major drain. Ask your service company what the opening includes if a substantial top-up is needed.
What does pool leak detection cost?
Typically $300 to $700. Worth doing if you are topping up noticeably more than evaporation would explain — on a heated pool an undetected leak is expensive twice over, in water and in heat.
