Quick answer
If you plan to use your hot tub through winter, it should enter cold weather already heating and circulating normally, with clean water, dependable filtration, the correct water level, a well-fitting insulated cover and no unresolved leaks or equipment warnings. Winter is much easier when you solve small problems before a cold snap turns them into urgent ones.
For hot tub owners in London, Stratford and surrounding Southwestern Ontario communities, the biggest change is not that you need an entirely different maintenance routine. It is that heat, flow, water level and cover condition become more time-sensitive when temperatures fall below freezing.
Choose the right winter path
Many modern hot tubs are built for year-round use, and a cold-weather soak is one of the reasons people buy them. Custom LeisureScapes carries Bullfrog, MAAX and OWOW hot tubs, but the exact cold-weather operating and winterizing instructions depend on the specific model. Always use the owner’s manual for your spa rather than assuming every brand is prepared the same way.
Go into winter with dependable heat and circulation, clean filters, stable water level, balanced water and a cover that seals properly. Build a habit of checking the spa after power interruptions, heavy snow and unusually cold weather.
Use a complete model-appropriate winterization process. Custom LeisureScapes offers professional hot tub winterizing and closing service that includes system draining, plumbing blow-out and mechanical winterization.
Interactive winter check
Choose your winter plan, then answer seven quick questions based on what you can safely observe today. The result is a maintenance guide, not a remote diagnosis.
Your winter plan
We’ll prioritize heat, circulation, water care and cover condition in your result.
Before sustained freezing weather
You do not need to rebuild your maintenance routine for winter. You do need to make sure the basics are working before cold weather reduces your margin for error.
Use current test results and the instructions for your sanitizer and water-care products. Persistent cloudiness, foam, scale or chemistry that keeps drifting is easier to correct before deep winter. If you are unsure which system or products you have, bring a product photo or water sample to Custom LeisureScapes for guidance rather than adding another chemical at random.
If your water is due for replacement, choose a mild-weather window and allow enough time for purging, draining, cleaning, refilling, priming and balancing. Custom LeisureScapes’ drain-and-refill guide specifically cautions against draining during freezing conditions unless the spa is being professionally winterized.
A dirty or damaged filter can restrict flow. Start winter with filters that are clean and in good condition, then learn what normal circulation looks and sounds like on your spa so you can recognize a change quickly.
Keep water at the level specified by the spa manufacturer. If the level is dropping faster than expected, look for dampness, drips or other signs of a leak. Repeatedly topping up a leak can hide a problem that becomes more serious when temperatures fall.
Check the fit, hinge, straps, handles, outer material and whether the cover has become unusually heavy. A properly fitting insulated cover helps retain heat, reduce evaporation and keep precipitation out. Custom LeisureScapes offers custom-fit replacement hot tub covers when the existing cover is no longer doing its job.
Keep a safe path to the spa and do not bury service-access panels under snow. You should still be able to check the display, water level, cover and visible equipment area after storms and power interruptions.
Keep enough sanitizer, balancing products, filter care and testing supplies to maintain the spa between store visits. Do not add extra product simply because it is winter. Follow current test results, the product label and your spa manufacturer’s instructions.
Heat retention starts at the top
The cover is one of the main barriers between warm spa water and cold outdoor air. A cover that fits correctly should sit evenly on the shell, close fully and remain manageable enough that you will actually open the spa for regular checks.
Custom LeisureScapes’ replacement-cover program is built around custom sizing. Their cover options include high-density foam cores, marine-grade vinyl, tapered drainage and locking straps. If your current cover is heavy, waterlogged, cracked or no longer sealing properly, replacing it can improve day-to-day winter usability and reduce avoidable heat loss.
Water care without guessing
Cloudy water, persistent foam, scaling and unstable chemistry are not automatically “winter problems.” They are signs that the water, filtration, bather load or treatment routine needs attention. The difference in winter is that draining, refilling and troubleshooting become less convenient once outdoor temperatures are well below freezing.
Test first
Use a current water test before making unfamiliar chemistry corrections. Appearance alone cannot tell you what the water needs.
Keep products compatible
Do not mix chemicals, combine leftovers or switch systems casually. Use the products approved for your existing water-care program.
Use local help when needed
Custom LeisureScapes has showrooms in London and Stratford and an online shop for spa chemicals, parts and everyday water-care products.

When cold weather changes the urgency
Not every spa issue requires an emergency call, but a heating or circulation problem deserves faster attention when the temperature outside is below freezing. Once warm water is no longer moving normally through the system, protecting plumbing and equipment becomes part of the problem—not just getting the spa comfortable again.
The set point has not changed, but the actual water temperature continues to drop or the heater is not recovering as expected.
You notice poor movement, a flow-related warning, unusual pump behaviour or a system that no longer circulates the way it normally does.
Persistent water loss, dampness around the cabinet or a visible leak should be investigated before low water interferes with operation.
If a breaker or protection device keeps tripping, do not repeatedly reset a fault you do not understand. Follow the spa’s safety instructions and request qualified service.
Small winter habits that matter
After heavy snow
Clear a safe route to the spa and remove excess accumulation from the cover using a method that will not cut, scrape or damage the cover material.
After a power outage
Confirm that the spa actually resumed normal operation. Check the display, water temperature and circulation rather than assuming it restarted correctly.
Before leaving town
Confirm water level, chemistry, cover security and normal operation. If you will be away for an extended period, arrange for someone to inspect the spa.
During extreme cold
Pay attention to new noises, warnings, falling temperature, weak flow or unexplained water loss. Cold weather is the time to investigate changes early.
Not using the spa this winter?
When a hot tub will be shut down for the season, the goal is not just to empty the shell. Water can remain in jets, plumbing lines, pumps, heaters and other low points. If that water freezes, expansion can damage components that are difficult and expensive to repair.
Custom LeisureScapes offers a dedicated hot tub winterizing and closing service for the London and Stratford area. Their service includes system draining, plumbing blow-out and mechanical winterization using specialized equipment. That is a very different process from simply letting the spa drain through its normal outlet.
Hot tub winter FAQ
Many hot tubs are designed for year-round use. The important winter basics are dependable heating and circulation, the correct water level, clean filtration, a properly fitting insulated cover and regular checks for leaks, error messages or changing equipment behaviour. Follow the winter operating guidance for your exact hot tub model.
If the water is due for replacement, doing the drain and refill during milder fall weather can be easier than waiting for freezing conditions. Custom LeisureScapes’ drain-and-refill guide advises against draining a hot tub during freezing weather unless it is being professionally winterized.
Use the operating range recommended by your hot tub manufacturer and appropriate for the people using the spa. Do not exceed 40°C / 104°F. Large temperature changes should not be used as a substitute for a properly insulated, correctly maintained spa.
A cover can become heavier as the foam takes on moisture over time. If the cover is waterlogged, sagging, cracked, difficult to lift or no longer sealing properly, have the fit and condition assessed. Custom LeisureScapes offers custom-fit replacement covers for hot tubs.
Treat a loss of heat or circulation as time-sensitive in freezing conditions. Safely note any error code or display message and contact a qualified service provider. Avoid repeatedly resetting a breaker or opening electrical and mechanical equipment you are not trained to service.
Not safely without completing the winterization procedure for the exact spa. Water can remain trapped in plumbing and equipment after the shell appears empty. Follow the manufacturer’s instructions or use professional hot tub winterizing service.
Custom LeisureScapes’ hot tub service department operates year-round. The company provides hot tub diagnostics and repair, professional winterizing/closing, hot tub opening, replacement covers and water-care products from its London and Stratford operations.
