Please beware of this operation! I have been to BDC many times over the years. I do not know when Sinan began handling their work, but I trusted that it was a reputable place and that he was a reputable dealer.
I had BDC/DEVCO install a very large window, several smaller ones, and a sliding glass door in our home. We had installed windows just like these in other areas of our home before without incident, so did not anticipate any problems. It seemed like a simple, straightforward project.
While we were on vacation, the windows went in. When we returned, to our disbelief, they had completely jerri-rigged some strange way of installing the windows and they were horrible! I called Sinan. He came over and gave us some far-fetched reason as to why these windows had to be installed in this manner--differently from all of the others, and why the resolution to the problem would entail removing all of our mouldings, the window sill, and a number of other things that made no sense.
Our painter came in, took one look at the windows and couldn't believe it. He offered to reinstall the window. I called Sinan. He said to tell the guy that if he thought he could do it to go ahead. The painter removed the windows and the rigging that Sinan had installed and put the window in. No big deal, no need to do all the things that Sinan was telling us we had to do, and the window looks great.
I deducted the amount the painter charged me for the reinstallation from the final amount paid to Sinan. Sinan agreed to the amount. We paid him the full amount less the amount of the reinstallation even though we still have the other smaller windows that he installed that have been put in in the same shoddy way.
Today we just received a letter from Sinan threatening us with a Contractor's Lien if we do not give him the balance of the money. My first read of this experience was that the contractor was sadly incompetent. Now I realize that he is also unscrupulous. Beware!!!!!
