What are window well covers?
Window well covers are solid or grated covers that go over the top of window wells. They come in many different materials, like steel, aluminum, plastic, or fiberglass. Covers can be permanent or removable. They can also open in different ways – some removable covers are on hinges, some slide to the side, while permanent covers need to be screwed in place.
Types of window well covers
There are a few main types of window well covers:
- Steel or aluminum covers – These metal covers are sturdy and long-lasting. They have a more industrial look.
- Plastic or fiberglass covers – Plastic covers can be transparent to allow in light. Fiberglass covers also let in daylight. Both these materials are inexpensive.
- Grate covers – Metal grate covers have an open design to allow more light in. They can be used with a clear plastic panel to provide even more light.
- Hinged covers – Hinged covers flip open for easy window access. They can be made from metal, plastic, or fiberglass.
- Sliding covers – These covers slide horizontally to open and close. They are usually made of plastic or fiberglass.
Benefits of window well covers
Using a cover over your window well has some potential advantages:
Improved safety
Window well covers prevent people, especially children, from falling into the well area. Uncovered wells create a falling hazard that could lead to serious injury. Covers act as a barrier.
Keeps out debris
Debris like leaves, dirt, mulch, and twigs can accumulate in open window wells. Covers prevent debris buildup, keeping your window well neat and tidy.
Protects from weather
Covers shield your window well from rain, snow, and other precipitation. This helps prevent water damage to your foundation or basement.
Discourages pests
Insects, spiders, snakes, rodents, and other pests can enter and nest in open window wells. Covers block access to these unwanted critters.
Adds insulation
Window well covers provide an extra layer of insulation over your basement windows. This can make your basement more energy efficient by preventing heat loss.
Improves security
Covers prevent intruders from entering your home through window wells. The cover acts as a barrier to deter break-ins.
Aesthetic appeal
For some homeowners, exposed window wells look untidy or unattractive. Covers provide a more streamlined, sleek appearance.
Potential disadvantages of window well covers
Although window well covers have benefits, there are also some potential drawbacks:
Reduced light
Solid covers, especially opaque metal ones, can greatly reduce the amount of natural sunlight entering your basement windows. This may limit what the basement space can be used for.
Moisture buildup
Covered window wells may allow condensation to build up inside the well. This can lead to mold, mildew, and moisture damage over time.
Difficult emergency escape
In case of fire or emergency, window well covers can make egress from basement windows much harder. Removing covers quickly would be difficult.
Higher cost
Covers aren’t hugely expensive, but they are an added cost. For homeowners on a tight budget, choosing uncovered wells may be more economical.
Potential trapped debris smell
A small amount of trapped debris that gets wet between the cover and window well could create unpleasant odors.
Key considerations for window well covers
If you’re deciding whether or not to add window well covers, keep these considerations in mind:
Code requirements
Some building codes require protective covers for any window wells deeper than a certain level, usually over 30 inches deep. Be sure to check your local requirements.
Material
The material you choose affects cost, durability, appearance, light transmission, and other factors. Compare options like metal, plastic, fiberglass, and grates.
Removable vs. permanent
Removable covers allow access to windows for cleaning and emergency escape. Permanent covers offer better protection and insulation but don’t allow window access.
Well size and shape
Measure your window well dimensions to ensure proper fitting covers. Covers come in standard and custom sizes.
Locks
Some covers can be locked for added security. This prevents unwanted removal of the covers.
Vents
Vented covers allow airflow to prevent moisture buildup. Solid covers should have proper drainage installed.
Child safety
For homes with kids, choose covers with safe, rounded corners and ensure they are securely installed to prevent access by children.
Cost of window well covers
Window well cover costs typically range from about $100 on the low end to $500 on the high end. The table below shows typical price ranges for different types of covers.
| Cover Material | Typical Cost |
|---|---|
| Plastic | $100 – $250 |
| Steel | $150 – $400 |
| Aluminum | $200 – $500 |
| Fiberglass | $150 – $350 |
Besides the cost of the covers themselves, there may be additional costs for hardware, locks, hinges, and professional installation if you don’t install the covers yourself.
Installation tips
Proper installation is key to getting the most from your window well covers. Here are some tips for installing covers:
- Carefully measure the dimensions of your window well opening before ordering covers.
- Check that covers are fitted tightly without gaps, but not so tight that they warp the window well frame.
- Anchor permanent covers securely using corrosion-resistant screws.
- Make sure hinged covers open fully without being obstructed.
- Seal any drain holes that may be needed to avoid moisture buildup behind covers.
- Caulk around edges of covers to seal out water.
- Consider using plastic film or plexiglass behind grate covers to prevent dust and debris entry but allow light.
- Make sure covers are sturdy enough that people cannot push them aside and gain entry.
- Test that window functions aren’t blocked by covers and emergency egress remains viable.
Conclusion
Window well covers offer notable benefits like safety, weather protection, insulation, and pest prevention. But they also have some drawbacks to weigh, such as reduced light and ventilation and potential moisture issues. Safety considerations are especially important if you have small children. Overall, covers are recommended for window wells over 30 inches deep, but shallower wells may benefit from open ventilation.
If you do install covers, plastic or fiberglass are cost-effective options, while steel and aluminum provide greatest durability. Be sure to carefully measure, secure the covers properly, and test for light and egress functionality. Window well covers require an initial investment but can enhance your home’s comfort and security for years to come.
