Serious Windows Reviews
I bought serious windows aprox 15 years ago and the panes are fogging. Would you gave a company contact for replacement? Thank you.

[Site Editor's Answer]
Peg, Serious is no long in business and honestly has been gone for so long that I'm not sure what to recommend. You could try Alpen HPP and see if there is any relief there. I would probably say you should find someone in the area to help you either replace the glass if possible...if this is not feasible, you may have to replace the windows. I can send you my list of recommended window brands and if nothing else you could have a few companies come out and give you some advice in terms of repair and/or replacement options and prices.

Serious Windows Complaints
I have a Serious window that has lost its seal (vapor has appeared between panes). It was manufactured in 2012. I’d like to replace or repair it. What are my options? Thank you,
Scott - Homeowner - from 2023
[Site Editor's Answer]
Scott, I honestly have no idea what your options are on this matter. Serious Windows no longer exists so I don’t really see what you can do here. You might want to use our service to find a window repair person in your area to fix the glass issues…this might be your best bet.

Serious Windows Problems
Hi Tim, we have Serious windows, which were purchased in 2010-2011. Some of the windows are in need of repair. Do you have any knowledge of how we can get repairs?

Karen, Serious Windows isn't going to be much help since they are no longer in business. I think my advise to you would be to go on yelp and look for a quality window repair person. Call them up and see if they will give you a free bid to come out and take a look at your windows. This would be where I would start out at least.

Hi Tim. My husband found the company that bought Serious. They are called Kensington HPP. Customer service number 725-845-5300. They helped us get parts we need ... just so you can help others

Wow, that's great to hear. I did know that Kensington HPP bought them, but typically a company will blow consumers off if it involves past asset purchases that they are no longer legally required to service...good to know Kensington stepped up...I will give them props on the site. Thanks for the info!

Serious Windows Warranty Claims
TIM, IS THE SERIOUS WARRANTEE STILL GOOD FROM 2010? I HAVE A WINDOW THAT IS CLOUDY. THANKS
Aremley - Homeowner - from 2017
[Site Editor's Answer]
Aremley, Serious Windows went out of business in 2012 and sold their assets to Alpen. So no, your warranty is no longer valid. Here is what I would do -- contact Alpen and explain the situation, they may be willing to help you out. If they are, definitely let me know and I'll post it on the website so that other individuals who purchased Serious windows will know that Alpen is willing to work with past Serious consumers going forward!

Serious Windows Reviews
I started out looking mainly at Gorell and Okna, but then I happened into a Serious dealer who suggested the Serious 300. The salesman says they're better than Gorell and Okna, and the price is higher. Most of what I've seen online says Okna and Gorell are great, and there isn't a ton of into about Serious, but I worked with this same company on our roof and they did a good job so I'm inclined to trust them. Any opinions?

Okna is the best of those by far. ( Okna Windows Reviews ) The company is stable and will be around a long time if you do have any problems, but they make a quality product. If you compare different stats, like u-values, ai, dp, etc, you'll see the difference. Serious has had some financial troubles, and I'm not sure they'll be around in a few years to honor the warranties. Gorell looked iffy for a while, too, but was recently bought by Softlite and that should fix those concerns.

Serious vs Inline Fiberglass Windows
I'm looking at Inline fiberglass windows, but they look a lot like Serious. What's the difference? I live in Ontario, Canada, and we have long cold winters. We're replacing south facing windows, with no trees blocking the sunlight. I really want the most energy efficient window I can find, we have to heat the home a large part of the year.

A lot of people are confused about Inline and Serious windows. The Serious windows are made from Inlines, they basically put on suspended film and call it a new window. Inline is just as good, has more styles to choose from, and cost less. Get a true triple pane if you're looking for energy savings and skip the gimmicks.

Serious vs Thermotech & Inline
I think Serious makes a good window, and I also like Thermotech and Inline. Serious makes a really good product with suspended film glass, the lighter weight makes the moving parts last a lot longer and you get more light coming through. Serious has been used in a lot of famous buildings, including the Empire State Building, plus they come with a lifetime guarantee. Thermotech is also great, they are more expensive but they have really great service, and I recommend them especially if you don't know anything about what you want or need. Inline is my third choice but still good.

Someone asked if the Serious or Infinity is better. I guess it depends on what you're looking for in a window. Serious makes a great energy efficient window, but the price is very high. The Marvin Infinity looks really good, but doesn't perform at the same level. The Serious 1125 comes in a casement, picture, or awning style, and it's one of the best windows out there as far as energy efficiency, but you might have to sell the house to pay for new windows!
The company's 725 line has single and double hungs if that's what you need. But if you can't afford them, Marvin is a good choice. Another thing to remember is that your weather has a lot to do with what's the best choice. The right window for Miami is probably not the same as the best window in Minnesota.

Serious Windows Quantum Reviews
Have you seen the Serious Quantum? It's amazing, well built, really good numbers. The only thing I don't like about it is the Heat Mirror, but that's on a ton of windows and a lot of people like it. I myself prefer a soft low-e coating, but Heat Mirror works.

Redesigns On Kensington Windows
Serious Materials bought some of the assets that used to make up Kensington Windows. They took a lot of the designs and facilities and renamed them as Serious lines. They updated some of the designs a little, but they still have pocket sills on some of them. I know a pocket cuts down on air infiltration but it grabs all the moisture and dirt. They do have Heat Mirror, which I like. The Kensingtons had some issues with fit and locking due to poor design, and I don't know if Serious has fixed all those issues.

Serious Windows Reviews
Right now I live in Fairbanks Alaska, but I'm building in North Carolina. I've designed an EcoPanel SIP home and I decided on Serious Windows to finish it up. I looked at a lot of different brands and spent more than 2 years researching them before making a decision. I wanted something energy efficient and green for an environmentally sound home. I'm going with their 925 line, 50 windows in the house and 15 for the garage. They are the most expensive option I considered, but I think they're worth it.
The Marvins were closest in price, but I decided to go ahead with the best. The fiberglass offers the most energy efficiency, and my home is designed to take advantage of geothermal heat so heat transfer is a big deal. I'd rather go all out on the windows and doors than waste my money on decorative extras.
However, I did have some trouble finding a dealer, but I ended up calling headquarters to get a name. I'm going through Joe Martin in Chattanooga, he's very knowledgeable on energy efficiency and was a great help in my design process.
