I installed Brock Windows and doors in 2017. I had several issues with the install at time of purchase (which I already wrote a review for) but the most recent was our sliding door. Since we still have warranty I called Brock to fix the lock on the sliding door. This is the second time we have had issues with the lock. The reception took my info to pass on to the repair dept but I never received a call back. I ended up looking up how to fix it on Youtube (whick worked!). Customer service at Brock is horrible I urge you to STAY AWAY!
