How To Cover Basement Windows From Outside

Okay, let's talk basement windows. You know, those little portholes to…well, usually dirt, spiders, and the occasional confused toad? We’ve all been there. You're trying to watch a movie, and suddenly, BAM! A beam of sunlight slices through like a laser, ruining the suspense. Or worse, you feel like you're starring in your own personal wildlife documentary, narrated by the buzzing of flies attracted to that little patch of illuminated grime. Covering those windows from the outside can be a game-changer.
Why the outside, you ask? Good question! Think of it like this: trying to block sunlight from the inside is like trying to stop a flood with a mop. It's better than nothing, sure, but you're mostly just delaying the inevitable. Blocking the light before it even reaches the glass is where the real power lies. Plus, let’s be honest, access to the outside of the window is much easier than trying to crawl through the dark, dusty depths of your basement. So, let’s dive in, shall we?
Why Bother Covering Them At All?
Besides the obvious (sunlight ruining your precious Netflix time), there are a bunch of legit reasons to cover those basement windows. Think of it as a tiny upgrade that punches way above its weight class.
Must Read
Security Boost
Let's face it, those little windows aren’t exactly Fort Knox. They're basically an invitation for opportunistic critters…or less welcome guests. Covering them up makes your home a little less appealing to anyone looking for an easy entry point. It's like putting a "Beware of Dog" sign out, even if your "dog" is a chihuahua named Princess Fluffybutt. It’s a deterrent, and deterrents work.
Energy Efficiency – Seriously!
That little window is a sneaky energy thief. In the summer, it lets in heat, turning your basement into a sauna. In the winter, it leaks heat, making your furnace work overtime. Covering it up is like putting a tiny sweater on your house. It might not look fashionable, but it helps! You could potentially save a few bucks on your energy bill. Think of it as found money – money you can use to buy more snacks for those basement movie nights!
Privacy, Sweet Privacy
Unless you enjoy being watched by the neighborhood squirrels, covering your basement windows is a must. Nobody wants to feel like they're living in a fishbowl. Especially if you're, say, practicing your interpretive dance moves in your underwear. (Not that I've ever done that…ahem.)
Okay, I'm Convinced. What Are My Options?
Alright, let's get down to brass tacks. There are several ways to tackle this project, ranging from the super-simple to the slightly-more-involved. Choose the option that best suits your budget, your DIY skills, and your tolerance for dirt.

The Quick and Dirty (But Surprisingly Effective) Method: Plywood
Yes, you read that right. Plywood. It's not pretty, but it gets the job done. Think of it as the duct tape of basement window coverings. This is a great option if you need a quick, temporary fix, or if you’re on a super tight budget.
How to do it:
- Measure your window(s). Accurately! Nobody wants a plywood square that looks like it was cut by a toddler with dull scissors.
- Head to your local hardware store and buy a sheet of plywood. They'll usually cut it to size for you, which is a huge win.
- Attach the plywood to the outside of the window. You can use screws, construction adhesive, or even just wedge it in place if the window well is snug enough. Just make sure it's secure! You don't want it flying off in the next storm.
Pros: Cheap, easy, and blocks out everything. Good for short-term solutions when you want to blackout your basement completely.
Cons: Not exactly aesthetically pleasing. Your neighbors might start to wonder if you're running a clandestine plywood storage facility in your basement. Might be temporary, not really weather proof.

The Slightly More Refined Approach: Window Well Covers
These are pre-made covers that sit over your window well, providing protection from the elements, critters, and prying eyes. They come in various shapes, sizes, and materials, from clear plastic to metal grates. It's like giving your basement windows a tiny little helmet.
How to do it:
- Measure your window well. Again, accuracy is key.
- Shop around for a cover that fits your well. You can find them at most home improvement stores.
- Install the cover according to the manufacturer's instructions. This usually involves attaching it to the window well with screws or clips.
Pros: Provides good protection from the elements, keeps out debris, and can improve security. Some models are even designed to let in light while still blocking UV rays. These are a more long term solution than using just a piece of plywood.
Cons: Can be a bit pricey, depending on the material and style. Some covers can be difficult to install, especially if your window well is oddly shaped. Also, make sure you purchase a high-quality one that will not turn yellow over time.
The "I'm Serious About This" Option: Egress Window Wells with Built-In Covers
If you're feeling ambitious and want to significantly upgrade your basement windows, consider installing egress window wells with built-in covers. These are larger window wells that are designed to provide an emergency exit from your basement. They usually come with a ladder or steps and a secure cover. Think of it as adding a miniature escape hatch to your home.

How to do it:
- This is not a DIY project for the faint of heart. It involves digging, concrete work, and possibly dealing with building codes. Hire a professional!
Pros: Significantly improves safety, provides more natural light and ventilation, and can add value to your home. Makes your home safer and more valuable at the same time.
Cons: Expensive, requires professional installation, and can be a disruptive project.
The Natural Look: Bushes and Shrubs
Okay, this isn’t exactly a “covering,” but strategically planting bushes or shrubs in front of your basement windows can provide shade, privacy, and even a little bit of security. Plus, it makes your house look prettier. It's like giving your basement windows a little green mustache.

How to do it:
- Choose plants that are appropriate for your climate and soil conditions.
- Plant them far enough away from the window well to allow for air circulation and to prevent root damage.
- Keep them trimmed and maintained. You don't want them to grow so tall that they block all the light.
Pros: Aesthetically pleasing, provides natural shade and privacy, and can attract birds and butterflies. It’s a more natural approach.
Cons: Requires regular maintenance, may not provide complete coverage, and can attract unwanted pests. Think about the roots growing and potentially damaging your foundation. Also, this method won't work well in the winter.
A Few Extra Tips and Tricks
- Consider the material: If you live in an area with harsh weather, choose a durable material that can withstand the elements. Wood can warp, plastic can crack, and metal can rust.
- Think about ventilation: If you're covering your windows tightly, make sure you have adequate ventilation in your basement to prevent mold and mildew growth.
- Don't forget about aesthetics: While functionality is important, you also want your window coverings to look decent. Choose a style and color that complements your home's exterior.
- Check your local building codes: Some areas have regulations regarding basement window coverings, especially if they affect egress.
- Critter Proofing: Ensure that whatever solution you are using is installed tightly to the frame of the basement window to prevent critters from sneaking in.
Final Thoughts
Covering your basement windows from the outside is a small project that can make a big difference in your comfort, security, and energy efficiency. Whether you choose the simple plywood solution or invest in egress window wells with fancy covers, the key is to find a solution that works for you and your home. So, get out there, measure those windows, and start covering! And remember, even Princess Fluffybutt can be a surprisingly effective guard dog…in spirit, at least.
Now, if you'll excuse me, I hear my Netflix calling. Time to enjoy a movie, without the distracting glare of the sun or the unsettling presence of a spider staring back at me.
