Imperium Window Series

Imperium offers three vinyl window series, which include the Galaxy, Imperial, and the GS Window Series (premium series). The company also offers doors in the following options: French Swing, GS Door Series, and the Imperial Door series.

Imperium Windows Warranty

The company states that it offers a limited lifetime warranty on all of their products. Beyond this, I couldn't find any additional information. I dislike when companies skimp on warranty information as I typically assume the worst - a pro-rated schedule, no transfers, no accidental glass breakage, they don't cover the labor cost to install windows, etc. However, I can't say one way or the other because the warranty terms are not listed.

Best Los Angeles Replacement Windows

I have a home that was built in the 195s. I love your website and all of its great information. We plan to replace all 17 windows, plus a patio slider. I have a quote for the Milgard Trinsic V300 that came in at $19k. Imperium gave us a quote for $16.7K, and Window World gave us a quote for their 6000 series at $14k. We are located in the greater L.A. area and would love to get some feedback.

[Site Editor's Answer]

Danny, I just don't know enough to comment on the Imperium cost quote. The Milgard Trinsic V300 is good, but I don't think it's worth $5K more than the Window World 6000 (although I would have to know what the actual window is that they are selling). So, for now, my pick would be the WW6000, although I am going to send you my list of windows in case you want to grab an extra bid or two!
