Kensington windows reviews

Update:  The friendly folks at Kensington HPP have reached out to us with some new info about their company and it’s relationship to another company formerly known as Kensington Windows.  This post is an update to an earlier post I wrote about Kensington.  Everything you’ll read in this post is accurate as far as I know based on my conversations with the folks at Kensington HPP.

So, with that said, if a google search for Kensington Windows lead you to this page you’ll fall into one of two camps.

If you have Kensington Windows in your house and you’re looking for warranty or service information:

You’ll want to pay close attention to when the windows were manufactured.  There was another company, legally unrelated to the current company, that went out of business in 2008.  They don’t exist anymore and if you have warranty issue you’re likely out of luck.

If your windows were manufactured after that you’re likely in luck and you can contact Kensington HPP or the contractor that installed them for service issues.

If you’re shopping for new windows and a contractor recommended windows from Kensington HPP then you’re in better shape.  Here’s the scoop on that company.  

After the old Kensington Windows company went out of business in 2008 and the assets of that company and another window manufacturer called Republic Windows in Chicago were purchased by Serious Materials out of California in 2009.  They were trying to get into the window business on the cheap during the financial crisis.

I remember reading an article about their maneuvers with the financing and the unions back then thinking they sounded like a smart group of people.  Unfortunately that plan didn’t work out so well and Serious left the window business in 2013.

A group of the former executives from the old Kensington Windows got together and reopened a new company called Kensington HPP that now offers windows in most of the eastern half of the country.  If you’re wondering Kensington HPP stands for High Performance Products.

They took over operations from Serious in 2013 so they’re been around in their current form for 4 years or so as of this writing.  That certainly doesn’t make them the lowest tenured company around, but we all started out somewhere.  My company is about to turn 10 years old and when we had only been in business for 4 years we still offered great service.

The models offered by Kensington HPP are:

  • Quantum 2
  • Huntington
  • Williamsport
  • Kingston
  • Euro Tilt and Turn

At this point I don’t have enough info about their products to offer great reviews, but if they send the info I’ll be happy to publish more content.

They are also the only vinyl window manufacturer in the country that uses heat mirror technology.  This is a 3 pane sealed unit with the center pane being a plastic material instead of glass.  I’ve heard of some rather high prices for Heat Mirror products.  To decide if it’s right for you be sure to get past the sales jargon and compare the efficiency ratings vs the cost.  You should be able to tell rather easily if the increase in efficiency is worth the increase in cost.

If I hear about any new info from the folks at Kensington HPP I’ll be happy to post it and if you have any experience with their company or their products feel free to post a comment for everyone to see.

    Here’s an interesting video I found. It seems that Serious had setup the whole IGU sealing system within that building…. being that they were architectural grade windows I’m pretty sure the glass spacers needed to be customized …. you can’t replace the whole window in an architectural landmark unless you replace it with architectural grade window …. So retrofitting the glass was the economical way of going about it… also NYC has very strict rules about landmarks/ historical buildings. They did the retrofit to make the whole building more energy efficient as per the NYSERDA initiatives of making all commercial buildings have less of a carbon footprint…. that was just a little bit of info that I know being in nyc and having seen different ways of insulating glass units/ packs…. and Kensington HPP now uses that same system in their vinyl windows…

    We replaced 14 windows in 2016 with Kensington double pane vinyl windows, at half the cost of the nearest competitor. It is now four years later and no complaints, even though we live in the cold winters of Minnesota. The house is nice and warm with no cold air leaks from these great windows. Great product!
