Learn how to replace a basement window in concrete with this DIY friendly video. Specifically, I will show you how to remove a basement window and install a new vinyl window.
To replace a Basement Window, you will need to follow these basic steps:
1. Purchase Replacement Window(s)
The first step in replacing basement windows is to order your replacement window(s). To do this, measure the rough opening of you concrete foundation window penetration and compare those dimensions to available replacement window dimensions. There are many different sizes and styles of windows, so spend sufficient time ensuring that the replacement window you purchase will fit within your existing window penetration.
2. Remove the Existing Window
The second step in replacing a basement window is to remove the existing window. Start by removing any screws or nails that are holding the window in place. Then, remove the glass panels (if possible). Next, use a reciprocating saw to cut the top of the window frame and then try to loosen the frame from the concrete it is embedded within. If the window is stuck, use a pry bar to carefully loosen it from the home's foundation.
3. Position The New Window in Place
Position the replacement window into the opening and center it as best as possible. Use shims to hold the window in place.
4. Level the Window and Install Shims
To ensure the replacement window is level, use a carpenter's level to check for any unevenness. Use shims to make any necessary adjustments to the window's level, placing them in the gap between the window and the rough opening.
5. Apply Spray Foam around the Perimeter of the Window
Once the window is in place, secured with shims, and level, apply spray foam insulation around the perimeter of the window. The spray foam will help seal any gaps and improve the energy efficiency of your home. Be sure to follow the instructions on the spray foam can and wear gloves and protective eyewear during this step.
6. Cut off Excess Spray Foam and Caulk Around Window
After the spray foam has dried, use a utility knife to cut off any excess foam that is sticking out. Then, apply caulk around the exterior of the window to seal any remaining gaps. This will help prevent air and water from entering your basement. If you have a damaged any of the concrete around your window, you can repair it with rapid setting concrete and trowel at this stage of the project.
In conclusion, replacing a basement window is a manageable DIY project that can improve the energy efficiency and overall look of your home. Be sure to take the necessary safety precautions, measure the size of the opening accurately, and use the right tools and materials for the job. With these steps, you can replace a basement window with ease and enjoy the benefits of a more comfortable and efficient home.

As a general contractor who has done this dozens of times you did it exactly the way that I would. The only tip that I could give you is after you apply that caulk spray a ammonia-free window cleaner on it as well as your finger and you can smooth it out and it won't stick to anything that you sprayed. You can also use a popsicle stick that is sprayed. Otherwise you did a fantastic job. I would make it a more obvious point to the diy to use the window and door spray foam because it doesn't have the PSI expansion of regular expanding foam. Which is exactly what you want on a door window 👍👍
I used this video to replace five basement windows just like these shown in the video. The most difficult part was removing the old frames, and I did have to buy an oscillating blade for this. Thanks, helpful video.
I think you just saved me $800 on a contractor. I'm going to replace my window, by my damn self.
Just make sure you don’t do it the way it was done in this video and you’ll be fine.
Caulk smoothing is a trigger for some folks😂 Every time I try and smooth it out, be it with a tool or finger i just make a bigger mess.
As long as the bead is covering what it needs to cover i leave it be.
I’ve enjoyed following your build and just started my own basement office build.
Good stuff, keep it coming.
You so humble. Thanks for sharing your wisdom
Attention DIYers!! When he is applying caulk along the bottom edge of the window, you’ll notice that he avoids filling in the two holes at the bottom edge. These holes allow water to drain out and should be unobstructed.
Good point
This is an excellent point. And if your window doesn't have those drains, you're going to need to try another method to cover the bottom (like aluminum) so you can leave it open. Never prevent water from having a way out.
Not to ask a dumb question- but the little rectangular shaped ones on the left and right? I want to make sure I'm following
@@oliviagonzalez7126 yes. The little rectangular holes at the bottom let water escape. You don’t want to cover those.
@@anthonyrandazzo8836 awesome! Thank you!
This is exactly what i was looking for, my house was built in the early 30's and has steel framed basement windows
Thanks for this information! I am getting ready to do a basement window! :)
Great video man! Building the courage to do my garage windows. How much smaller were your window than your opening?
Looks good enough for me...I have the exact same old basement windows you have. The home I am working on was built in 1920 with sawmill oak where the 2" X 4"s are exactly 2 inches by 4 inches.
Here's a tip I've learned while using spray foam, apply painters tape to all the surfaces surrounding the area you down want the foam to make contact, this will make clean up much more efficient.
That’s a good tip! Thanks for watching!
nice work
Thanks!
Isn't this how Kramer installs the Air Conditioner? Just kidding, but I am really surprised you used no brace at all, I would really be worried someone simply pushing the window in or out or over time foam insulation cracking or drying and causing bigger gaps. Is there any chance of this holding any reasonable force (security or someone with big hands trying to pull the window open, and taking the whole window with him)? Thanks so much for the easy way to install window, though! :)
Very good 😊👍👍👍🇹🇭
Thanks!
So Andrew is the disclaimer because you are showing us how to change windows wrong? Jk... the video gave me a lot of good tips!!! TY
I looked for RedHeads to physically mount the window in the opening with hardware. A bunch of choices. Use a concrete bit, drill 2 holes on each side, (after level/plumb with shims), right thru the window frame, inside the side tracks, thru the shims, and into the concrete. Be mindful of the head you choose so that it can be flushed or counter-sunk, depending on the window design and not interfere with the window opening or closing. Worked marvelous. Then I continued with the spray foam and everything else. Turned out great and I know it will be harder to kick-in as opposed to just the foam. Thanks for the video!
Great points. Thanks for that man! I I'm installing my first basement window in my house and it has an old wooden frame and I didn't know if I should rebuild the frame or just remove and then install in concrete but I didn't like the idea of only foam holding window in 😅
That turned out great! Once you frame the inside with jams, header, and sill, the window should be pretty stable and not fall out for sure. You did the concrete and caulking outside for a good snug fit, plus the expanding foam. The only thing I would have done outside would be to smooth out the caulk. Otherwise, well done and thanks for the tips!
Appreciate it, John! And I agree - I don’t think that’s going anywhere. And I here you on the caulk but that type is almost impossible to smooth out. It’s not like silicone, that’s for sure . Thanks for watching!
A+
Looks like the same American Craftsman windows that were installed in my basement. But I cannot figure out how to remove the movable part so i can get material through the opening. Do you know if the movable part can be removed?
Doyou mean the sash itself? There is an operator that opens the window and should disconnect where it attaches to the frame. Same thing for the hinges. Have a second hand incase the sash just drops.
Where did you find replacement windows?
A++
Thanks Patrick!! 👍💪🏻
What is holding the window in place? Foam??
Seem like u can kick that window in
This was my question
Pretty sure he just showed that he went over the foam with concrete.
He did good. If someone wants to get in, they're going to get in no matter how or what you use to install the window, if the opening is big enough. If that's a big concern try installing glass block windows instead.
So no screws holding the window in? That to me is a horrible idea just relying on spray foam and caulk to hold the window in place! Thats very sketchy! I do windows all the time and i never once didnt not screw the window to the concrete or above wood plate.
You didn’t use screws to fasten the window to the concrete.
I was wondering about that
He said the spray foam and caulk will hold it in place. Which it will for the most part. Until 10 years later when it falls out.
What about a situation with a similar-sized window that needs to be switched for a window with a cat door? I cannot find a basement window with a pet door anywhere, and I'm struggling to find any information about how to let a pet outdoors from only that window. Hmm ............
Most people make "catio's" and leave the window open. It's a fenced in outdoor area for your cat
Wait, where's the step where you anchor/fasten the window to the house? Can't just be wedges/shims and foam/caulking holding that in place. If it is then it's not proper...
He explained in the video why he didn’t. You did watch the video right??
If you're not going to use concrete screws to hold the window in place I would at least use construction adhesive. Spray foam will not hold well for years to come. Also I wound mount the window flush to the sill plate. There's no reason to shim it from the top.
Hmmmm I think I’d pass on that way of installation.
Nah you’re tripping man stay away from the caulk gun too
Seriously? Dude... Come on. Smooth your calk out with a fingertip at the minimum. It will look and work so much better.
This guy literally did everything wrong. Do not follow any steps he did
Don't just criticize, how would you do it?
