I wanted to give a shout out to Sebastian Regent the owner of Dorr for giving me the customer service you would expect. After having an issue with a broken crank on a window Sebastian immediately got back to me with a solution. I felt like my issue was very important to him and he wanted it fixed ASAP and me satisfied. Thats the kind of window dealer I want to deal with. I would highly recommend Sebastian and his company. Thanks Dorr for walking the talk.....
