WeatherLok windows are made by Atrium windows (owned by Cornerstone Building Brands), although when I visited their website on September 10, 2026, the site was down. In general, Atrium Windows manufactures a lower end to mid range vinyl window. The Weatherlok window line is a cheap vinyl windows that is sold to consumers looking for an affordable window option.

| Window Series | Total Quote Installed | Editor's Takeaway |

| Superior Pro WeatherLok 3201 | $11,200 | Editor Would Eliminate This Option |

"Project deets: 11 windows, several tall and oversized. Looking to maximize energy efficiency and sound control. We've narrowed it down to the following double hung / double pane windows and we live in outside of Atlanta, Georgia fyi (maybe this doesn't matter)."

Editor's Advice:
The Weatherlok windows are junk as far as Im concerned, so toss that one. The Berkshire Elite is a decent window, but Id prefer the Soft-Lite Bainbridge over that one. Then we come to the Okna 800 for $700 more. This is the winner in this race. The 800 series is a great window and absolutely worth the difference in price.

Weather Lok vs Window World 4000 And 6000
| Window Series | Total Quote Installed | Editor's Takeaway |
|---|---|---|
| Weather Lok Windows | $5,350 | Lower Quote — Premium 3900 Or 3500 Preferred |
| Window World 4000 Series | $6,050 | Higher Quote — 6000 Upgrade Recommended |
| Window World 6000 Series Upgrade | $6,365 | $315 Upgrade Over 4000 Series |
"Hi Dane, I have received two quotes so far and waiting on a couple more contractors to come by. So far is seems like the contractors are using the Weather Lok windows or Alside windows. I am in northern Illinois. 9 windows being replaced, all currently single hung and from the original construction about 25 years ago. Standard windows, nothing fancy or odd shaped sizes.
The quotes received so far are $5350.00 for the Weather Lok and $6050.00 for the Window World 4000 series. The 4000 can be upgraded to the 6000 series for an additional $315.00 total.
The Weather Lok are closer to what I budgeted for windows, but the warranty Window World gives is impressive.
I have reached out to a soft lite dealer, but they have not responded to my request yet. I can reach out to an Alside dealer who offers the full Alside line if you think they would be a better choice.
If I cannot find one of your mid grade vinyl window choice dealers to give me a quote, which of the Weather Lok or Window World windows do you think would be the best option?"
Tom - Homeowner - from 2019
Editor's Advice:
Tom, almost $600 per window for a single hung window from Weather Lok, which I believe sells a relabeled Atrium product, seems like a lot. But then again the Window World 4000 is even more expensive. If you go with the WW option, definitely upgrade to the 6000 series.
If you are going to go with the Weather Lok window, I'd stick to their premium 3900 or 3500 series myself.
I'd get the bid on the Alside Mezzo, a decent mid grade window. The Soft-Lite Pro or Classic is a very solid vinyl window and the clear winner of all of the options you have so far.

WeatherLok vs Simonton vs ClearView vs Alside Preservation
| Window Series | Total Quote Installed | Contractor Takeaway |
|---|---|---|
| ClearView Windows | $5,500 | Not Enough Familiarity To Recommend |
| WeatherLok Windows | $6,400 | Okay Window — Below Simonton |
| Simonton Windows | $7,200 | Preferred Option Of The Four |
| Alside Preservation | $8,500 | Not Preferred |
"I've received quotes for WeatherLok, Simonton, Alside Preservation and ClearView windows from two different companies for 14 double hung windows. They do their own installation and have a long list of references for me to check so I feel like the install quality is covered. I can't figure out the differences between these brands. The ClearView is $5500, the Weatherlok is $6400, the Simonton is $7200 and the Preservation is $8500."
Bradley - Homeowner - 2012
Editor's Advice:
I don't think there's much to love with the Preservation and the Weatherlok is an okay window, not the same quality as the Simonton (although I need to know the actual models to compare apples to apple.) I know nothing about the ClearView so I won't comment on it. Simonton is a decent vinyl manufacturer and probably your best best out of those four. I might get more quotes if I were you.

"Does anyone have any info on Weatherlok windows?"
John - Homeowner - 2011
Editor's Advice:
John, Weatherlok is actually made by Atrium but rebadged and sold as Weatherlok window. Atrium does this for a numerous of different window lines. One of their main manufacturing plants is in North Carolina. They may also have one in the Dallas area, but I'm not sure. As to the quality of the window, I couldn't say. Atrium windows reviews are just so-so.
