The best thing about Brocks is the Windows they use which are actually made by North Star - a different company.
The first time I worked with Brocks, I wasn't quite happy with their installers. The reason I brought them for the second time was I like the quality of North Star windows and hoping to get a more qualified installer this time but unfortunately it didn't happen.
In fact, the second installer replaced 4 windows and caused noticeable damage on the wall paint around 3 windows.
I called Brock and asked for compensation. They requested pictures of the damaged areas which I took and emailed them. Few days later, the installer called me and offered a $100 credit as compensation but I told him this should be reflected on the Brock invoice and I'm not dealing with him directly. The week after, someone from brock called me and the issue was escalated to John who was said to be the owner of Brocks. John only called me to ask how soon they'd receive the payment. I asked him if he had few minutes to listen to my feedback. He said yes and I started explaining why I'm unhappy with Brock's service. Apparently, he didn't have the patience to listen to his customer. We only talked about less than a minute. Suddenly, he put me on hold and transferred me to their accounting which right away asked: "so how are you paying the outstanding amount?"
This is neither respectful nor professional and particularly I didn't expect it from a person at this level.
