Clear polycarbonate window well covers are a practical choice for keeping leaves, rain, and other debris out while allowing light into a basement. The best option depends mainly on your well’s measurements and whether you need one cover or a two-pack. The 39-by-16-inch cover suits a smaller opening, the 41-by-18-inch two-pack works for buyers covering two wells, and the 59-by-38-inch cover is the largest listed choice. Measure the well before choosing: these products are covers, not complete window well assemblies.
| Product | Best suited for | Listed size |
|---|---|---|
| Clear heavy-duty polycarbonate cover | A smaller well | 39 x 16 inches |
| Two clear polycarbonate covers | Two matching wells | 41 x 18 inches each |
| Clear polycarbonate cover | A larger well | 59 x 38 inches |
| Heavy-duty clear polycarbonate cover | A well close to 40 x 18 inches | 40 x 18 inches |
| Reversible bubble-style cover | A lightweight plastic option | 42 x 15 inches |
39 x 16-Inch Clear Polycarbonate Cover
This clear, heavy-duty polycarbonate cover is listed at 39 by 16 inches. Its product name specifies UV resistance and tear-resistant, waterproof, and windproof qualities. It is best for a buyer whose well measurements are close to this smaller listed size and who wants a clear cover. It was selected as a compact option among the listed products. The listing says “only cover,” so buyers should not expect a complete well or separate installation hardware based on the supplied product details.
Two-Pack, 41 x 18-Inch Covers
This two-pack includes clear polycarbonate covers measuring 41 by 18 inches each. The listing describes them as all-weather covers intended to help keep debris out, with UV-resistant, tear-resistant, waterproof, and windproof qualities. It is best for a homeowner with two wells that take the same size cover. The pair format is the reason it stands out for multi-well coverage. Check both openings before ordering: the set’s value depends on both wells matching the stated dimensions, and the listing identifies these as covers only.
59 x 38-Inch Clear Cover
At 59 by 38 inches, this is the largest listed cover in this selection. Its clear polycarbonate construction makes it a candidate for buyers who want a transparent cover for a substantially larger opening. It is best for a well whose measured dimensions align with the listed size; it was selected to provide a larger-format alternative to the compact options. The supplied product information does not list additional weather-resistance specifications, so buyers should verify the listing details and fit rather than assume features not stated here.
40 x 18-Inch Heavy-Duty Cover
This clear polycarbonate cover measures 40 by 18 inches. Its product name specifies heavy-duty construction along with UV resistance and tear-resistant, waterproof, and windproof qualities. It is best for buyers whose well is closer to 40 inches long than the 39- or 41-inch alternatives. The near-matching dimensions make it a useful comparison for wells around this size. The listing says “only cover,” so check what is included and confirm that the cover can be secured as needed for the installation.
42 x 15-Inch Reversible Bubble Cover
This 42-by-15-inch reversible bubble-style cover is a lightweight plastic option. The listing says its clear finish lets light in while blocking debris and rain, and that it is designed to be easy to install. It is best for buyers who prioritize a lightweight cover and want the listed insulation benefit for a basement window. The listing also specifies a weight capacity of zero pounds, so it should not be treated as a load-bearing cover. Confirm the product’s dimensions against the well before selecting it.
Buying Guide: How To Choose A Window Well Cover
How should you measure a window well?
Measure the opening where the cover will sit, including its length and width, and compare those numbers with the product’s listed dimensions. Do not choose solely by the window size: the cover is intended for the well opening. Account for the shape and lip of the well, and verify the manufacturer’s fit guidance when available. Even a small size mismatch can make it harder to position or secure a cover.
Should you choose polycarbonate or plastic?
The listed polycarbonate covers emphasize clear construction, and several specify UV resistance and weather-related properties. The bubble-style plastic cover is described as lightweight, reversible, easy to install, and helpful for insulation. Compare the actual product claims rather than assuming all clear materials have the same strength, installation method, or weather performance.
Do you need one cover or a two-pack?
Choose a two-pack if you have two wells that both fit the listed 41-by-18-inch dimensions. For a single well or openings with different measurements, compare individual sizes instead. A multi-pack is not a substitute for checking each well separately.
What should buyers check before installation?
Confirm what comes in the package, how the cover is intended to be attached, and whether the listing identifies it as cover-only. Keep access to the basement window in mind, especially if it is used for emergency egress. Do not assume a cover is designed to support a person; the bubble-style option specifically lists a zero-pound weight capacity.
Frequently Asked Questions
Do clear window well covers still let in light?
Clear covers are designed to allow light through. The bubble-style listing specifically says its clear finish allows light into the basement.
Will a cover keep rain and debris out?
Several listed products describe protection from debris and rain or state waterproof properties. Check the individual listing because claims vary by product.
How do I know which size to buy?
Measure the well opening and compare both dimensions with the cover size. Select a product only when the measurements and fit requirements align.
Are these covers load-bearing?
Do not assume they are. The bubble-style cover lists a zero-pound weight capacity, and the supplied details do not establish that the other options support a person or other load.
