Alside Excalibur Windows Reviews

Alside windows reviews and ratings

The Alside Excalibur window was the most popular window produced by Alside for many years.  Millions of these windows have been installed all across the country.  The Alside Excalibur window is slated to be discontinued in 2014 and replaced by the newer Alside Mezzo window.

The Alside Excalibur window has been a popular option because it meets the needs of most homeowners at an affordable price.  This window came with standard features that we’re available options on competing models.


Standard features on Alside Excalibur windows:

  • Double strength glass
  • Heavy duty screen frame
  • Steel reinforced sashes
  • DP50 rated for strength
  • Sloped sill

Despite the list of standard features, the Excalibur window was often criticized online.  This had a lot to do with the fact that it was sold by Window World under the Comfort Word 4000 brand at very low prices.  This made the competition offering similar products at higher prices uncomfortable.

Not all criticism of the Alside Excalibur was unfounded.  The design was a little past its prime and several elements were due for an upgrade.  In addition the manufacturing tolerances weren’t as tight as they could have been which led to inconsistent quality.

What about the Alside Excalibur warranty?

The warranty from Alside was always pretty solid and that was certainly the case with the Excalibur windows.   The warranty covers the glass seal, the windows and the hardware for as long as the original purchaser lives in the home and it is transferable when the house is sold.

  1. This review is awfully vague. What specifically about the window was not up to snuff? What specific improvements does the Mezzo have over its predecessor?

    1. The Excalibur had higher air infiltrations ratings, higher u-factors, lower max sizes and bit of an older design. It wasn’t a bad product, but the competition had passed it by. If they were going to continue to compete they needed to improve the product.

  2. Hi window dog! I have a question for you and hope you can answer it! I have 2 vinyl replacement windows in my house and have had several contractors look at them ( broken pane) to see what brand the are so I can get it repaired. One of the contractors thought they were a alside Excalibur ? The only info I can find on the window is a s/n 128-161164 – PO: 1864. Also there’s a gold AAMA label that says Series: 0201/A201 Double Hung P.L. # 004-011

    1. The one contractor was correct. Model 0201 is an Alside Excalibur. That model has been discontinued, but replacement parts are likely still available. Good luck with your project!

          2. Looks like your keyboard might not be working right either…. Your best bet is to call the company that you bought the windows from. They should be able to help out.

  3. Hi! I have a window broken and the net cut. They are with life time warranty, but I can find way to make contact and ask for repairing! Does anybody know how to do it?

    1. Call the dealer who installed them. They should be able to help out. You can also file an Alside warranty claim online now. Let know if you can’t get the installer and I can send you the link.

  4. I had Alside Excalibur windows installed in my home about 10 years ago and I want to add an additional window. What Alside window model would matche the frames I have. The Excaliber Model# is 0201 – Double Hung with the Climate Tech Elite glass package

    1. The Alside Excalibur window was discontinued a while back, but you can get a very similar product with the Alside Fusion window. The Alside Mezzo will be a little bit nicer, but not the same dimensions.

  5. Are the Alside Excalibur Windows and the Alside Fusion Windows interchangable? I have about 5 double hung windows that have either the top window or the bottom that have lost the internal gas. I am hoping to not have to replace the entire window. Thank you.

    1. Hi William, you probably have a warranty on your Excalibur windows so the best way to get new sashes for them is just to order them up from Alside.
