What are the different types of winter cover, and what are the pros and cons of each?
[open]
The main types of winter cover are the tarp type, fine woven material measured by their scrim or weave count. The higher the skim or weave count, the closer weave the material has. They come in solid or mesh varieties.
For inground pools, or pools with a full deck, you may want to opt for a safety cover, which also come in either solid or mesh varieties.
Safety covers are secured by anchors and springs, lying flat over an inground pool. It’s pulled taut and may be either solid or mesh. While it does keep debris out of your pool, the main reason people buy this type of cover is to prevent people or animals from falling into the pool when it’s closed. These types of covers are only for inground pools and require installation into the deck to keep the cover safe and secure.
A solid cover is laid out over either an above ground or an inground pool, and secured with water bags (on inground pools) or a cable and winch (on above ground pools). These keep debris out of the water while the pool is closed. Water will also collect on top of the cover, causing it to sag, and you will have to pump the water off the top of the cover with a winter cover pump.
Mesh covers allow rainwater and snow melt to drain into the pool while keeping larger debris out. The debris will dry on its own, making it much easier and faster to remove. However, you will need to deal with rebalancing your pool water come springtime. This type of cover will need to be supported in heavy snow load areas.
How do I choose the right size pool cover for my pool?
[open]
To choose the correct size pool cover, measure the maximum length and width of your pool, from the inside edge to the inside edge, including any steps or protrusions. Select a cover that matches your pool’s dimensions, as manufacturers will incorporate the necessary overlap for a proper fit.
For rectangular and oval pools, measure the length and width. For round pools, measure the diameter.
How long do winter covers generally last?
[open]
Standard winter covers generally last up 3 - 5 years, while more durable winter covers can last upto 15 years. Their lifespan depends on factors such as the severity of winter, proper maintenance, and the quality of the cover.
Can I reuse the same cover year after year?
[open]
Yes, you can reuse a winter cover, but its lifespan depends on how well you maintain it. A good cover can last for several years with proper care, including cleaning and drying it thoroughly before storage. You should inspect it for damage, such as tears, before each use, and be prepared to replace it if it becomes worn out.
How should I store my winter cover when not in use?
[open]
Clean your winter cover with a multipurpose cleaner, even if it looks clean. Let it dry completely to prevent mold and mildew from growing. Then, fold it neatly and store it in a safe, dry place over the swimming season.
Does the color of the cover matter?
[open]
Darker colors absorb more heat, which can reduce the chance of your pool freezing in the winter; however, they also lose their color more quickly than lighter colors.
What kind of maintenance does the cover require?
[open]
Winter cover maintenance includes regularly clearing off debris, water, and snow accumulation, checking and adjusting straps for proper tension, and periodically inspecting your cover for damage.
Use a leaf blower, leaf net, or a soft-bristle pool brush to clear your cover of any debris. Also, ensure that you remove any debris from under the cover and your deck.
If a large puddle of water accumulates, you should drain it by using a cover pump. If you live in an area with a lot of heavy snowfall, you may want or need to remove it carefully to ensure you don’t damage your cover any further.
What features should I look for in a winter cover?
[open]
When you’re choosing a winter cover, look for durability and weather resistance, a secure and proper fit, and the right material and type for your needs. For example, if you want complete blockage, choose a solid cover; or select a mesh cover for drainage.
If you choose a solid cover, you’ll want to look at the scrim count. This refers to the tightness of the material's weave, and the higher the scrim count, the better the quality and the heavier-duty the cover. If you live in an area with mild winters, then you’ll likely get away with a lower scrim, but if your area is prone to heavy winters, then you’ll need a higher scrim count.
What would happen if I didn't use a cover to close my pool and left it open?
[open]
It is highly recommended that you cover your pool during the winter. A winter cover blocks much of the debris from entering your pool, and slows down the speed at which any chemicals you add deplete.
Is a mesh or a solid winter cover better?
[open]
This can depend on many different factors. A mesh cover is ideal for areas that receive heavy snow and rain, as it allows water to drain through easily. However, it also allows sunlight and small debris, such as dirt, to enter, requiring more care when it’s time to reopen the pool.
A solid cover usually means less work in the spring (as it blocks sunlight and small debris), but it requires more maintenance and monitoring during the winter. Since it’s solid, it won’t drain automatically, so you’ll need to periodically pump water off the cover.
What if I can't find the exact size of my pool, or have unique curves to work around?
[open]
When in doubt, always size up! Since your winter cover is already designed to have additional overlap, if you have extra material, you will simply need to wrap or tie it back more. Sizing up ensures that any unique curves and shapes are adequately covered.
Do I need anything else to install my winter cover?
[open]
The process for installing your winter cover varies depending on whether you have an above ground or an inground pool; therefore, what you need also varies.
For above ground pools, you use a cable and a winch to secure the cover. If you live in a windy area, then consider getting cover clips, wall bags, or a cover seal to ensure your cover is even more secure. You’ll also want to get an air pillow to secure below your cover, which helps absorb energy as the freezing water expands.
For an inground pool, you need enough water bags or Buffalo Blizzard® Blizzard Blocks to go around the perimeter of your pool. Once they have been filled ¾ with water, they will anchor your winter cover in place.
Why are most covers black on the underside?
[open]
The black underside of winter pool covers helps block sunlight and inhibit algae growth over the winter, making for an easier spring opening.
Can you patch a rip or a tear in the cover?
[open]
Always inspect your winter pool cover before putting it on for the season. It’s best to inspect it for holes or damage in the spring. If the tear isn’t too big, you will be able to patch it up; however, it may just be a temporary solution to get you through the season.
