They have a nice selection of Milgard windows and sliding doors, which are vinyl or fiberglass. I feel that although these windows are vinyl, their appearance is quite good in comparison with other window companies. I really enjoyed the information shared by the vendor and appreciate the openness and honesty about the actual time involved with ordering the windows and actual replacement, which could take 3 months from their Simi Valley company.

Rarely write reviews but it was impossible to get a quote. I called them requesting a quote on Feb 22nd. They told me to email them. I did. No confirmation. Followed up 2 days later. No response. Called them again, said they received and are working on it. Called 4 days later. Asked me to send floorplan. I did. No response. Each time I call, they said they got it but they never once called me or responded to my email.

A prospective customer comes in with a $30,000 order and they don't even bother? What the hell is wrong with them. Obviously I'm not going to bother with this company and you shouldn't either.

Got there to see if I can get a small mirror for a cabinet Owner call the tech so he can tell me the price. So he did and I agree to the price the owner start doing the order and increase the price by 5 more dollars. So I left and I don't think I will return to that place.
