I'll leave others to comment specifically if they have experienced any of those contractors, however generally speaking, I'd suggest searching for a company that has a sufficient number of reviews (dozens), and that they are predominantly positive as opposed to "mixed".... You mention that you have had "quite a few estimates", have you had others with more positive feedback, but that were perhaps higher in price? ... Unless California has cost of living lower than the rest of the country (I believe the case to be the opposite), these prices seem very low which probably coincides with the less than stellar review quality. For a good, reputable company and window you will likely see numbers closer to $20k +/-, especially if many of them are tempered glass.

Hi Stef,

Just to throw another option out there, have you considered Origin? We are well reviewed and offer a range of aluminum doors and windows.

Feel free to take a look or send us a message if you have any queries. :)

The only thing i know about califiornia is the fact that they have alot of problems thanks to that childish clown of a governor.

the 8K is very low. that's about $360 per window, including install. those have to be some really cheap windows and really cheap labor. they're all vinyl retrofit, yes? 200-300 per window, is a cheap window. I have one. looks ok but never quite seals properly.

any of your windows require flashing of any kind? I'd be concerned the cheap bid is going to bypass that step.

why don't you call out a really good, high end window company, and just see what their bid is and what type of install they do. If they come in at 25K, then you know these other guys are doing some really cheap work.

Looks like the “origin“ of that post is pure spam. At least offer some advice if you are going to shamelessly pitch your product, sheesh.

Ami is also known as alside stef g, lots of talk and feeback on them.
