When it comes to pool safety and maintenance, mesh pool covers are often praised for their affordability and ease of use. They are commonly used around in-ground and above-ground pools to prevent debris from entering the water and reduce evaporation. However, like all pool safety products, mesh pool covers have their drawbacks. This article explores the various cons of mesh pool covers, helping you make an informed decision about whether they’re the right choice for your pool and family.
Understanding Mesh Pool Covers
Before diving into the disadvantages, it’s helpful to understand what mesh pool covers are and how they work. Mesh pool covers are typically made from woven polyethylene material with small holes that allow water and air to pass through. They are designed to lie flat over the pool surface and are anchored using grommets and tension springs or a track system around the pool perimeter.
They are popular due to their durability, affordability, and ease of installation, but it’s important to carefully evaluate their downsides, especially when it comes to safety, maintenance, and effectiveness in different climates.
Top Cons of Mesh Pool Covers
Mesh pool covers offer several benefits, but they are not a perfect solution for every pool owner. Here are the main disadvantages to consider:
1. Limited Safety for Toddlers and Small Children
One of the most significant drawbacks of mesh pool covers is their inadequate safety for young children. While mesh covers may keep out large debris, the holes in the fabric are often large enough for a child’s limbs or even a small head to pass through, presenting a serious drowning risk.
Although some mesh covers are advertised as “safety covers,” it’s important to note that not all of them meet the safety standards required for complete childproofing. The American Society for Testing and Materials (ASTM) F1346-91 sets guidelines for safety pool covers, including load-bearing capacity. However, standard mesh covers often do not comply with these rigorous safety standards, unlike solid vinyl pool covers.
Takeaway: If you have toddlers or young children, a mesh cover may not be enough to prevent accidents.
2. Difficulty in Preventing Algae Growth
Because mesh covers allow sunlight and rainwater to pass through, they are not effective at preventing algae growth. Algae thrive in warm, moist environments with access to sunlight—precisely the conditions that exist under a mesh pool cover during the off-season.
In fact, rain and debris that make it through the mesh can mix with pool chemicals, dilute them, and create an environment conducive to algae blooms. As a result, pool owners often find themselves spending more time and money on chemical treatments and cleaning when mesh covers are used.
Key Considerations
- Sunlight penetration: Mesh covers don’t block sunlight, which encourages algae growth.
- Debris accumulation: Leaves and dirt can still collect on the pool bottom under the cover.
- Water clarity: More frequent cleaning and chemical balancing may be needed.
Takeaway: If reducing algae maintenance is a priority, mesh pool covers may not be the best option.
3. Inability to Retain Heat and Water in Cold Climates
In colder regions where pool use drops dramatically in winter, maintaining water temperature and preventing heat loss becomes important—if only to reduce strain on the pool heater when reopening. Mesh pool covers, however, are ineffective at insulating the water.
Because they allow water to flow in and out, they fail to:
- Trap heat from the sun.
- Minimize evaporation, which can lead to further heat loss.
This makes mesh covers less energy-efficient compared to solid covers, which are better at retaining heat and conserving water by limiting surface exposure.
Comparative Data: Water Loss and Insulation
| Mesh Pool Cover | Solid Pool Cover | |
|---|---|---|
| Insulation Efficiency | Poor | Excellent |
| Evaporation Control | Low | High |
| Heat Retention | Poor | Good |
Takeaway: In cooler areas, mesh covers offer little help in preserving pool temperature or reducing water loss.
Maintenance and Longevity Concerns
Beyond safety and performance issues, mesh pool covers can be difficult to maintain and may not last as long as other cover materials.
4. Frequent Need for Cleaning and Drying
Since mesh pool covers do not fully seal the pool, debris can still pass through or collect on the surface. This means you must routinely clear leaves, dirt, and pine needles from the top of the cover, especially during fall and spring when wind carries such materials.
Moreover, moisture can become trapped beneath the mesh, creating a breeding ground for mold, mildew, and algae on the cover itself. This requires seasonal cleaning and drying, which can be time-consuming and physically taxing.
Takeaway: Mesh covers need continued maintenance, contrary to the myth that they’re low-effort.
5. Susceptibility to Wear and Tear
While mesh covers are often made from UV-resistant polyethylene material, prolonged exposure to the elements—especially sun and wind—can still degrade them over time. Grommets may rust or loosen, and the webbing can stretch or tear, compromising the integrity of the entire cover.
Unlike solid vinyl covers, which are reinforced for strength, mesh covers are inherently more fragile, particularly around the anchor points.
Common Signs of Degradation
- Fraying or tearing at the edges and grommets
- Fading due to long-term UV exposure
- Accumulation of dirt and grime that’s hard to remove
Takeaway: Mesh pool covers may need to be replaced more frequently than other types of covers.
Limitations in Pool Closure and Winterization
Proper winterization is critical for extending the life of your pool and equipment. Here’s where mesh pool covers fall short.
6. Incomplete Protection During Pool Closure
When closing a pool for winter, a cover needs to provide a comprehensive barrier against contaminants, freezing water, and chemical imbalance. Mesh pool covers can allow leaves, seeds, dust, and even small animals to enter the pool, which can make opening the pool in spring much more labor-intensive.
Additionally, because water can pass through, freezing conditions may cause the cover to bulge or tear if not properly tensioned and secured. In areas where freezing is common, this can result in more work and higher risk for damage.
Winter Cover Comparison
| Feature | Mesh Cover | Solid Cover |
|---|---|---|
| Debris Exclusion | Poor | Excellent |
| Chemical Protection | Low | Moderate |
| Winter Durability | Fair | Good |
Takeaway: Mesh covers offer less effective protection during long-term pool closure.
Environmental and Practical Considerations
Mesh pool covers aren’t as eco-friendly or user-friendly as they might appear at first glance.
7. Ineffectiveness in Reducing Chemical Usage
Because mesh covers don’t fully prevent evaporation or chemical degradation, pool owners often find that they’re still spending a considerable amount on chemicals to maintain clarity and balance.
Chlorine and other pool treatments break down faster when exposed to sunlight and rain, which mesh material allows through. This limits the cover’s ability to decrease the environmental and financial cost of traditional pool maintenance.
Takeaway: If reducing chemical use is a goal, a mesh pool cover may not make a significant difference.
8. Limited Impact on Water Conservation
Water conservation is a growing concern, especially in arid climates like California, Arizona, and parts of Texas. Mesh pool covers allow water to evaporate at a relatively high rate because they offer limited barrier protection.
In contrast, solid safety covers can reduce evaporation by up to 95%, according to studies from the U.S. Department of Energy. This not only conserves water but also lowers utility and refill costs.
Takeaway: If water conservation is a priority, mesh pool covers are less effective.
9. Not Fully Automated
While automatic pool cover systems are becoming more popular for their ease of use and efficiency, most mesh pool covers are not compatible with such systems. They are usually removed manually and stored when the pool is in use, adding to the physical effort involved in daily or weekly pool access.
This is a major disadvantage for those with mobility concerns or those looking for convenience.
Takeaway: For those seeking automation, mesh covers are not an ideal option.
Cost vs. Value: Are Mesh Pool Covers Worth It?
Despite their drawbacks, mesh pool covers are often cheaper and more breathable than heavy-duty solid covers. But does this affordability justify the trade-offs?
10. Lower Upfront Cost May Lead to Higher Long-Term Expenses
Yes, mesh pool covers usually come at a lower initial price point, but this can be misleading. Over time, the need for frequent repairs, cleaning, additional chemicals, and earlier-than-expected replacement can make them more expensive compared to investing in a durable solid safety cover upfront.
Moreover, the lack of safety for children may prompt additional investments in fencing or alarms, adding to total costs.
Cost Analysis Over Five Years
| Expense Type | Mesh Pool Cover (Estimated) | Solid Vinyl Pool Cover (Estimated) |
|---|---|---|
| Initial Cost | $150–$400 | $400–$1000 |
| Repairs & Replacements | $200–$300 | $0–$100 |
| Chemicals & Cleaning | $100–$150/year | $50–$100/year |
Takeaway: While mesh covers are cheaper initially, their long-term inefficiencies can increase overall costs.
Conclusion: Choosing the Right Cover for Your Needs
Mesh pool covers offer benefits such as cost-effectiveness, ease of installation, and lightweight design, but they come with trade-offs. Key cons include limited safety for children, ineffectiveness at preventing algae, higher maintenance needs, and inadequate insulation and water conservation properties.
Before making a decision, consider the primary purpose of your pool cover. Are you focused on safety, saving on maintenance costs, or protecting the pool during winter? Your answer will determine whether the advantages of a mesh pool cover outweigh its disadvantages and whether you should invest in a solid safety cover, automatic system, or alternative material.
For many pool owners, especially those in cold climates, child-friendly homes, or environmentally conscious households, the drawbacks of mesh covers outweigh the benefits. However, for those with a tight budget, clear water access needs, and regular maintenance availability, mesh covers can still serve a useful purpose.
Ultimately, the best pool cover is one that meets your unique needs, safety concerns, and environmental values. Take time to evaluate your priorities—and consider consulting a professional if you’re unsure. Your decision will contribute to a safer, cleaner, and more efficient swimming environment.
Are mesh pool covers safe for children and pets?
Mesh pool covers are generally considered safer than solid covers because they allow water and debris to pass through, reducing the risk of standing water accumulation. However, they are not completely childproof or pet-proof. Small children or pets can still potentially slip through the gaps in the mesh, especially if the cover is not properly secured or stretched tightly over the pool.
While some mesh covers are designed to bear weight and meet safety standards, they should never be relied on as the sole safety measure for pools. Additional precautions like fences, alarms, and supervision are necessary to ensure the safety of children and pets around the pool area.
Do mesh pool covers provide adequate winter protection?
Mesh pool covers are commonly used for winter pool closure because they allow rain and melted snow to drain through the fabric. This helps prevent water from pooling on top of the cover, reducing strain on the material and the support system. However, they are less effective than solid covers at keeping small debris like leaves, dirt, and fine particles from entering the pool.
For pool owners in regions with heavy winters, mesh covers might not offer the level of protection needed to keep the pool clean and minimize chemical usage. Solid covers, though requiring manual water removal, often provide a better barrier against debris and sunlight, which can promote algae growth even in colder months.
Can mesh pool covers prevent animals from getting into the pool?
Mesh pool covers can sometimes deter small animals from entering the pool, but they are not completely effective. Animals such as birds, rodents, or even small mammals may still land on or fall into the cover and become trapped between the mesh and the water surface. The gaps can pose entanglement risks, particularly for wildlife like frogs or birds trying to escape.
For better animal deterrence, consider installing a solid safety cover along with additional measures such as fencing or motion-activated sprinklers around the pool area. These precautions can help keep wildlife away and reduce the risk of drowning or injury.
Are mesh pool covers easy to install and remove?
In terms of installation, mesh pool covers are relatively straightforward to set up, especially if they are custom-fitted for the pool’s shape and dimensions. Most systems use a track along the pool’s edge and support straps or a reel system for opening and closing the cover. However, the process can be physically demanding and requires proper securing to ensure safety and durability.
Removal and reinstallation for seasonal use can also be time-consuming. Because mesh covers aren’t completely waterproof, some pool owners may remove them during summer, only to face reinstallation challenges when winter arrives. Lack of practice or improper storage can further complicate the process, making it essential to follow manufacturer guidelines carefully.
Do mesh pool covers help with heat retention?
Mesh pool covers do not significantly aid in retaining heat because they allow air and water to pass through. Unlike solid thermal covers or solar blankets, which trap heat from the sun and reduce evaporation, mesh covers have minimal impact on maintaining or raising pool water temperature. This makes them less effective for extending swim seasons or reducing heating costs.
For pool owners who rely on heating systems or solar gain, using a solid insulated cover is the better option. Mesh covers are better suited for safety and winter protection rather than temperature control, so those seeking energy efficiency should look for alternative cover types.
How durable are mesh pool covers over time?
Mesh pool covers are typically made from strong, UV-resistant polyethylene or polypropylene materials that offer decent durability. However, prolonged exposure to the elements, especially direct sunlight, can break down the fibers over time, causing the cover to fray or weaken. The straps and support systems can also wear out, especially if not properly maintained.
With proper care and maintenance, a mesh pool cover may last anywhere from five to ten years. It’s important to regularly inspect the cover and hardware for signs of wear, tighten as needed, and ensure the water drains properly. Despite their durability, mesh covers may not withstand extreme weather conditions as well as solid covers can.
Do mesh pool covers require maintenance and cleaning?
Yes, mesh pool covers require regular maintenance to ensure they remain effective over time. Debris can collect on the top surface and around the edges of the cover, which can lead to staining or premature wear. Periodic cleaning with mild detergent and water helps remove dirt, algae buildup, and other contaminants that may degrade the material.
Additionally, it’s important to inspect safety covers annually for signs of stretching, tearing, or damage to the fastening components. If not stored properly during off-seasons, mesh covers can develop mold or mildew, especially if kept damp. Proper drying and storage are essential to prolonging the life of the cover and ensuring it functions safely when reused.
