Estimate: On time & not a waste of time. Accurate estimate and willing to match legitimate competition. Agreement: Clear communication of product, timeframe, warranty, and work to be done. Work: As scheduled, clean, neat, attention to detail, and overall quality work. Deniz is a professional and master at his craft. He takes pride in his work and will make sure the job is done as best as possible. As a potential customer and eventually a customer, I felt like I was a priority at all times. He has a great relationship with his crew and they are hard working which is great to see. I highly recommend working with Deniz as he is one of the rare "old school" honest and reliable businessmen I've dealt with as a homeowner.
