Many homeowners with above ground pools wonder if they need to take their pool down for the winter or if they can leave it up. There are pros and cons to both options that need careful consideration. In colder climates, leaving an above ground pool out during winter can lead to damage from freezing temperatures, heavy snow loads, and high winds. However, taking down a pool is a big job that many want to avoid if possible. This article examines the key factors to weigh when deciding whether to leave an above ground pool standing through winter.
Quick Answers
Here are quick answers to common questions on whether above ground pools can be left out in winter:
- It depends on the climate. In milder climates, above ground pools may be fine left up. In colder climates with freezing temps, pools should be taken down.
- Leaving a pool up risks damage from freezing water expanding, wind, and heavy snow loads on the pool walls.
- Taking down a pool requires disconnecting plumbing and electric, dismantling walls, and storing the components.
- An above ground pool left standing needs to be prepped – cleaned, water lowered, filters removed, skimmer winterized.
- The costs of any repairs or replacement from winter damage can outweigh taking it down.
- If carefully winterized, some brands such as Doughboy pools may be fine left up year round.
The Case for Leaving a Pool Up
Many pool owners want to leave their above ground pool up through the winter if they can. Dismantling an above ground pool is an enormous job. Here are some of the arguments for leaving it up:
- Avoids dismantling work – Taking down an above ground pool requires emptying the water, removing all connections and pipes, taking apart the top ledges and uprights, disassembling the liner, and carefully stacking and storing all the parts. This is days of difficult and labor intensive work.
- Prevents liner damage – The vinyl pool liner is one of the most expensive parts of the pool. Take down risks rips, tears or creases forming in the liner that may require replacement.
- Saves set-up time – Putting an above ground pool back up in spring already takes several days. Leaving it up avoids repeating this.
- Maintains level surface – Dismantling the pool means the ground and base may shift over winter. Leaving it up maintains a flat, level base.
- Retains landscaping – The area around an above ground pool often has decking, fencing, landscaping and patios added. Leaving the pool up avoids disruptions to the surrounding area.
Many homeowners decide the considerable time and hassle of taking down their above ground pool makes it worth trying to overwinter it standing if possible.
The Case Against Leaving a Pool Up
On the other hand, there are good reasons many pool experts recommend taking down an above ground pool for winter. Here are the main risks to be aware of:
- Freezing damage – Any water left in the pool or plumbing can freeze and expand, causing cracks, splits, and ruptures. This can damage the pool frame, walls, liner and equipment.
- Pool collapse – The weight and pressure from heavy ice, snow, or rainwater on the pool walls over months can lead to complete collapse. The walls are not meant to withstand these forces when empty for long periods.
- Blowing over – Strong winds are common in winter. The uprights anchoring the pool walls can be compromised or shear off, causing the empty pool to blow over.
- Debris damage – An empty pool can collect blowing leaves, dirt and other debris over winter. This material contaminates the pool in spring.
- Pest infestation – Rodents and insects can infest the empty pool walls and liner, causing damage and requiring treatments.
- Liner degradation – Pool liners left exposed and unprotected from sun, pollution and weather will degrade substantially faster.
These kinds of damage often cost as much to repair as simply replacing the entire pool. Pool experts recommend cautious homeowners avoid these risks by taking down their above ground pools for winter.
Preparing a Pool For Winter
If you decide to try and leave your above ground pool up through the winter, there are steps to take to prepare it:
- Clean the pool walls and floor thoroughly and treat with algaecide.
- Remove any water from pool plumbing lines.
- Insert plugs in skimmer and return ports to prevent nesting animals.
- Ensure water is 1-2″ below skimmer opening to prevent ice expansion damage.
- Test water balance and shock treat before closing to prevent algae growth.
- Cover pool with properly sized winter cover tightly secured to keep out elements.
- Clear any overhanging tree branches.
- Check anchoring straps are secure and adjust as needed.
- Lubricate threads on tension rods and clamping components.
- For soft sided pools, remove top ledges and store indoors leaving walls in place.
Proper winterizing can help minimize risks but does not guarantee the pool will make it through extreme winter weather unscathed.
Winter Considerations By Region
Your location’s winter climate is a major factor in determining if you should leave a pool standing. Here are considerations for different regions:
Cold and Snowy Climates
In regions like the Northeast and Midwest with regular heavy snow and sub-freezing temps, leaving above ground pools up year round is not recommended. Pools in these climates should be fully disassembled for winter storage to avoid almost guaranteed damage from the elements.
Mild and Moderate Climates
In warmer regions like the South and Southwest with milder winter weather, above ground pools stand a good chance of surviving the winter undamaged if properly winterized. Just be prepared to take action if an unusual cold snap occurs by temporarily covering the pool.
Coastal Areas
In coastal regions, the major winter threat comes from strong ocean winds rather than cold and snow. Take extra care securing all anchoring systems if leaving a pool up. Consider partial take-down options like removing side walls but leaving the bottom tracks in place.
Northern Locations
Some northern areas with warmer winter microclimates, like the Pacific Northwest, may allow leaving a pool up with vigilant winterizing precautions. Ensure the winter cover can handle any potential heavy wet snow loads.
Check local averages for temperature lows, typical snowfall, and maximum wind speeds when deciding if leaving the pool up is worth the gamble.
Winterizing An Above Ground Pool
If you do decide to leave your pool up, here are key tips for proper winterizing:
Clean The Pool
Thoroughly vacuum and brush the entire pool. Pay extra attention to water line and floor. Use pool cleaner to remove oils and biofilms. Check and adjust water balance. Shock treat the water. Add a winterizing algaecide.
Remove Water
Lower water level to 1-2 inches below skimmer opening. Open drain plugs to remove any water from plumbing lines. Use a wet/dry shop vac to vacuum water from jets and pumps. Leave drain plugs out over winter.
Check Components
Inspect pool components for damage. Look for corrosion and cracks from normal summer use. Replace anything compromised to withstand winter stresses. Ensure skimmer lid, return covers and any gaskets are in good shape.
Pool Walls
Check anchoring straps are tight and properly driving anchoring rods into the ground. Remove and store top rails and ledges indoors if pool has soft sides. Lubricate any o-rings and gaskets. Verify verticals are all straight and plumb.
Liner
Clear liner of any debris. Vacuum thoroughly. Scrub any problem areas. Check seams and repair any small tears. Manage any lifted corners. Treat with winterizing chemicals. Center a float so rainwater drains.
Winter Cover
Cover the entire pool with a properly fitted heavy-duty winter cover. Solid covers without mesh handles heavier snow loads. Use cover pumps to prevent any water buildup. Securely anchor cover to pool frame every 2-3 feet.
Equipment
Detach all hoses and pipes from pumps and filters. Move ladders, rails, chlorinators and cleaners indoors. Drain and store hoses and pumps. Lubricate o-rings and gaskets. Plug skimmer, return and inlet openings.
Surrounding Area
Clear overhanging tree branches. Ensure adequate drainage slope around pool. Secure any loose decking or fencing materials. Store any patio furniture, toys or decor items.
Regular Checks
Periodically check on the secured pool during fall and winter. Ensure water is not accumulating. Re-anchor and tighten any attachments. Remove snow buildup. Look for any rodent or pest infestation.
Types of Winter Pool Covers
Choosing the right winter cover is key to protecting your above ground pool during cold weather shutdown. Look for:
Solid Covers
Made from polyethylene, canvas or mesh reinforced vinyl, solid covers shed rain and snow, retain heat, and prevent light exposure. Handle heavy snow loads well. More expensive but offer the best protection.
Mesh Covers
Less expensive option but drain away melting snow so avoid large accumulations. Mesh allows light and air exposure so anchor well. Need constant monitoring and clearing after storms.
Water Tube Covers
Floating covers using water-filled tubes keep snow out while allowing rainwater to drain. Require active management to maintain tubes. Can scrape against pool walls in wind.
Automatic Covers
Motorized covers operate on tracks to fully cover and uncover the pool. More costly but very convenient and secure protection. Needs power source to operate in winter.
While tarps and plastic sheeting may seem appealing budget options, the lack of strength can lead to tearing and billowing from winds or pooled melting snow.
Preparing An Above Ground Pool for Opening
After surviving the winter, prepare your above ground pool to reopen for the season. Steps include:
Drain, Clean and Scrub
Drain any standing water from winter rains. Remove the cover. Clean out any debris that collected over winter. Scrub walls. Vacuum liner thoroughly. Check for any rodent or insect damage.
Remove Plugs and Reattach
Replace drain plugs. Reattach all hoses and pipes to pumps and filters. Check o-rings and gaskets before reconnecting. Have a professional check electric connections.
Check Pool Frame and Walls
Inspect the entire pool structure closely for any damage or shifting over winter. Look for cracks, leaks, damage around skimmer. Tighten any loose bolts or connections. Straighten vertical uprights.
Set Up Deck Equipment
Move ladders, rails, chlorinators and other accessories back into place around pool. Clear away any debris around pool. Reinstall anchor hardware for any safety covers.
Refill Pool and Balance
Refill the pool slowly over 24 hours. Avoid putting any strain on the liner. Add starting dose of shock. Balance chemicals and get filtration running again. Brush walls and vacuum as filling.
Watch For Leaks
Carefully check newly refilled pool for any small leaks at seams and connections. Catch and repair any leaks immediately before they grow worse.
With proper preparation for opening, your above ground pool should be sparkling clean and ready for summer enjoyment again.
Costs of Repairing Winter Damage
If your above ground pool does suffer winter damage, repairs can become expensive. Typical costs include:
| Repair | Cost |
|---|---|
| Liner replacement | $400 – $800 |
| New pool wall panels | $100 – $300 per panel |
| New upright supports | $50 – $150 each |
| Skimmer repair | $100 – $250 |
| Plumbing repairs | $200 – $500 |
| Pump/filter replacement | $300 – $1000 |
| Underground pipe repairs | $500 – $2000 |
| Complete pool replacement | $2000 – $5000 |
These costs often make dismantling and seasonal storage the most cost effective option, especially in cold climates.
Factors When Choosing An Above Ground Pool
When shopping for an above ground pool, consider how easily it can be winterized if not leaving it up year round. Key factors include:
- Pool Material – Vinyl, steel, resin and other materials vary in durability and ease of seasonal installation.
- Wall Shape – Straight or sloped walls impact how snow and debris shed off the cover.
- Wall Height – Taller walls may require complete dismantling when vacant.
- Wall Thickness – Thinner gauge materials are more prone to collapse or bending.
- Vertical Supports – Look for stronger metal uprights versus cheaper plastic versions.
- Top Ledges – Choose durable, weather-resistant connecting edges.
Consult with pool pros on brands and models built with disassembly and seasonal storage in mind.
Conclusion
While leaving an above ground pool standing year-round avoids a lot of work, in many climates the risks of winter damage outweigh the benefits. With proper preparation, some pools in warmer regions may survive winter intact. Ensure the structure is reinforced and winterized for the conditions. Be ready to take action during unusual weather. Compare the costs of dismantling versus potential repairs. With careful assessment of these considerations, pool owners can make the best decision for their situation on leaving their above ground pool up through winter.
