I would recommend running away from anyone suggesting MI in any way shape or form. There are many other replacement window manufacturers that will be better, list you area on here and one of the replacement window guru's will give you some advice.

Thanks for the response. I am in South Jersey - outside of Philadelphia.

When i sold them Superseal was always a decent product that i found had knowledgeable sales people and good customer service. I would see if you can find a lumberyard or installer who uses this brand or vinyl replacements. Also they are in NJ

What about Alliance? I can get that locally. We will actually be installing the windows ourselves - with help from family (carpenter).

MI makes a good Professional series window that is pretty good for California. MI makes different windows for different parts of the country. Milgard and Simonton are good national brands.

Thank you for the info. There are no Milgard dealers with 100 miles of my location - I will look into Simonton. How is the MI profession series different from the Designer series?

Don't buy MI WINDOWS you will regret it! We just spent $30k and got their 'sculpted sdl', What they advertised and what we got was completely different. Deceptive Advertising! The grid they did have on the windows was applied at the job site as they 'forgot' to add them on the order. They were applied by a random contracted company with a razor knife and to say they looked shoddy is an understatement. What's even worse is they are completely ghosting us. Customer service DOES NOT EXIST.
