We have lived in every time zone in the country and renovated many homes along the way. All prior renovations pale in comparison to the home in Greenwich, CT that DAS Custom Builders renovated for us. I have never seen such quality, efficiency and timeliness. Every project was done on time, on budget and to the highest standards. The entire experience was like magic.

We were very pleased with the job D.A.S. did on our gut renovation. They did a great job from the planning stages through the renovation to assisting us in getting ready to move in. Both Doug and Chris were able to make changes in the field and on the spot that improved the functionality and flow of our modern farmhouse renovation. The subs they used were very efficient and always on schedule. We would be very confident in using them again.
