Beware! Don't get ripped off with this company. If only there was a no stars option. Our sales rep was terrible to get in touch with when we had questions after signing the contract. At the initial consultation, 2 sales reps arrived and we were pressured to sign a contract. $3000 deposit lost, no windows and a hard lesson learned. Do not let anyone pressure you into anything!
