BUYER BEWARE.
Ordered 16 windows for my property. Some of the windows were crooked. No I'm not talking about the window opening, I'm talking about the window shashes. They were 1/8 of an inch longer on one side than the other. YES THE SHASES WERE NOT SQUARE. See photos attached. They refused to talk to me even though I paid for the windows. When the installer called, the owner tried to convince him to discredit me. When he told them we already measured the windows, the owner told the installer to never let the customer measure the windows.
Wow.

I use to buy my windows here, but today I decided to but somewhere else, they being rude to you when you call them ,if you need to know a price they ask you to stop by the office instead of just give u a price by phone, their prices are a little higher than other places, and the quality is not the best,

If you can't find the size of your window in a retail store this is the place . All windows are custom order to your specifications

Didn't have the best experience just getting an estimate. Seemed like there was some kind of language barrier in addition to disinterest in my business. Two stars for replying and answering my questions - quote was simply much, much too high for the work compared to other contractors (did not actually visit in person though).

Horrible phone service I called to ask about getting someone to come and give me a window installation estimate and the lady just ignored me question and said " installation ?...." I repeated the question and she said " You need installation?" So I just said yes after 3 tries and she just told me to call some other person that does contracts. I'm just amazed this is a business.

There is a woman there i want to say she's polish and seems to be the manager who is really rude. Went in there to get some broken windows repaired and I forgot my wallet, she would not let me leave them there while I went to get money I had to haul my broken windows out again. You must pay all upfront even though their paper work says 50% deposit. I decided to take my business somewhere else and avoid my frustration with rude people (polished manager to be exact)
