MI vs Simonton Windows

Dear Dane, we are in the process of replacing windows and have gotten a quote from an installer for MI Energy Core windows. However, after doing some research online, it appears that MI windows are a lower quality window and have gotten some bad reviews (as well as a class action lawsuit).

We are looking for a good quality mid-range window. We basically need 8 23"W x 59"H double-hung windows and 10 23"W x 59"H single hung windows. Looking at your website, Simonton appears to be a good brand. However the series names that are listed on the website do not match up with the collection names on the Simonton website. I'm assuming they just came out with new names? Can you recommend which Simonton collections are the better quality ones and which to stay away from? Is there another brand that you recommend over Simonton?

We live in the mountains outside of Albuquerque, NM. Our house is pretty shaded, but we do get quite a bit of sun, as well as 19" on average of rain and 59" of snow (not sure if any of this matters). Also, do you recommend vinyl over aluminum (or fiberglass)? Thank you very much for your time,

[Site Editor's Response]

Melissa, I would have to agree to the MI is not typically on many contractors top 10 list. The Energy Core is not bad though, although I haven't seen numbers on it. In terms of good mid range vinyl windows on the west, I would say look at Milgard, Amerimax and Anlin. Milgard will be available for sure, Amerimax possibly and I don't know whether Anlin has reps in your area.

I would say stick with vinyl, although fiberglass is certainly an option. Aluminum is really only something you should consider if you are in very hot climates, which Albuqueque is not based on the fact that you get that much snow. Fiberglass options should include Marvin Infinity, Inline, and Milgard Ultra.

Simonton is a good brand, probably not as good as the ones I mentioned, although it all depends on which model you select. I like their 9800 Impressions, and their Reflections 5300 and 5500 series.

MI Cutting Edge 1650 Windows

I had whole house window replacement (25 units) in September, 2008 with subject model. They had a ten year "warranty." To date, three have failed seals. The installation contractor is no longer in business and unreachable. Can anyone suggest a reputable contractor to replace the windows? I would prefer the same model for conformity's sake. Otherwise, suggest a higher grade brand with a like or similar appearance to the subject model. Thanks.

MI has a new Energy Core line that looks like it might be good. My biggest problem is it has a pocket sill, which I really don't like unless you have an impact window or some other good reason. Their other lines are nothing special. You can find plenty of others for around the same price with a much better track record as far as satisfaction, efficiency, and performance.

MI vs Viwinco

Viwinco makes a lower end window. They're on par with Silverline or MI. If you need a cheap window, they aren't the worst you can do, but if you're going to live in the home for a while, try for something a little better. Oknas or Sunrise, Himark, Softlite, all of them are so much better in terms of performance and looks. Of course, sometimes that just is out of budget, and you have to do what you have to do. Really, you want a window with a u-factor of .28 or lower, a DP rating of at least 50, and air leakage under 0.07.

MI vs Milgard

I'm getting two windows replaced and every quote I get seems to confuse me more. I can't afford to do all of the windows at once so I am only doing the two worst "leakers". I have quotes for 3 Milgards or an Amerimax with 2 MIs. But when I went to look at the Milgards again to try and decide, I saw the Andersen Series 100 and loved them. One installer said they are really good for the weather here in Arizona.

I'm in LA, not exactly the same weather but not too far off. The Milgards and Amerimax are all good choices. The Andersens, I'm not so sure about. They have a new Silverline that might be worth it and might not.

MI Energy Core Windows

I like the new Energy Core better than their old lines, but they still can't compete with most other brands. Builders go with low quality windows because they're cheap, and when you buy thousands of windows the money adds up. You want a real window for your house, not cheap junk that's only made to look good long enough to sell. Go with Sunrise, Gorells, Okna, SoftLite, they're all great.

Builder Grade Windows

MI windows are made for builders. They're cheap, designed to look good just long enough to sell the house. They aren't a window that anyone wants to live with. You'll be stuck dealing with flimsy materials and poorly made frames. You'll be replacing them in 5 years.

MI Window Warranty

My house has MI windows that are about 15 years old. I've heard they have a lot of problems, but I've been impressed with mine. Their warranty was better than a lot that I looked at and when I did have a minor problem they stood by it with no arguing. They replaced 15 year old glass at no cost to us, and not everyone would do that.

Xacts vs Ply Gem

Allied Building Products has a private label window called "Cutting Edge" and I'm trying to figure out who manufactures it. Any ideas?

Jay - Homeowner from 2010

[Contractor Response]

They're made by MI. They are also sometimes called Xacts. They are a cheap, builder grade window designed to be the lowest cost possible. If you have your heart set on Allied, look at the Ply Gem Premium or Great Lakes 5000. Before you buy anything take the time to check out Okna, Sunrise, Polaris, and SoftLite. With any of those, you'll be getting a window that's worth your money and won't fall apart in five years.

Good Customer Experience

We looked at three options when we got our windows. Pella from Lowes, Simonton or CertainTeed from Home Depot, all with a local installer. We liked the Simontons, but finally decided on MI Xacts, which are made by the same guys who make CertainTeeds. They are identical to the Bryn Mawr IIIs. The installation was great, plus the installer had worked with the windows before. He didn't cut corners and the whole thing was done neatly and carefully. He did the trimming and priming and some really nice caulking and touch up work. The windows all work really well and look great. Plus it only cost us $3600 for 9 windows.
